Therefore, when the motor 222 drives the eccentric disc 252 to rotate, the protrusions 2522 of the eccentric disc 252 sequentially abut against the two opposite first sides 2511 each time the eccentric disc 252 rotates, so that the movable frame 251 slides reciprocally along with the rotation of the eccentric disc 252, the sliding direction is consistent with the axial direction of the connecting shaft 258, and the plug 3 is plugged and unplugged. It will be appreciated that the eccentric disc 252 may be shaped other than a fan, as well as an eccentric, a cam, or any other shape that enables this.
The spring piece compressing mechanism 5 includes a lever member 51 and a link member 52, the lever member 51 being located below the movement clamping mechanism 21, and the length direction being along the movement direction of the movement clamping mechanism 21. The lower end of the moving clamping mechanism 21 is provided with a hinge shaft 213, both ends of the hinge shaft 213 penetrate the lever member 51 in the horizontal direction, and both ends of the hinge shaft 213 are rotatably connected with the moving clamping mechanism 21, and the hinge shaft 213 is disposed near the first end of the lever member 51. The first end of the lever member 51 is bent in an S-shape to form a clamping opening 511 for receiving the free end of the locking spring 31.
The shape of the linkage member 52 is approximately an incomplete ring, and the axis of the linkage member 52 is the same as the axis of the connecting hole 253, and the upper end of the linkage member 52 is fixedly connected to the lower surface of the eccentric disc 252, so that the movement track formed by the rotation of the linkage member 52 along with the eccentric disc 252 is a ring. The link 52 includes an abutment 521 for abutting against the second end of the lever member 51, the abutment 521 being a lower surface disposed horizontally. The second end of the lever member 51 is also located below the eccentric disc 252, and when the second end of the lever member 51 is not in contact with the abutment 521, the abutment 521 is higher than the second end of the lever member 51, and the locking spring 31 is in an uncompressed state at this time. The protrusion 2522 includes a circular arc edge far from the base 2521 and straight edges connected to both ends of the circular arc edge, wherein the distance from any position on the circular arc edge to the connecting hole 253 is identical, the intersection of the circular arc edge and the straight edges is an abutting position 2523, and the abutting position 2523 is both an insertion position and a withdrawal position. The first side 2511 of the movable frame 251 close to the movable clamping mechanism 21 is set as an insertion end, and the first side 2511 far from the movable clamping mechanism 21 is set as a withdrawal end.
When the abutment position 2523 abuts against the insertion end, the whole process of inserting the plug 3 into the socket 41 is shown, in which the abutment 521 rotates along with the eccentric disc 252 and gradually approaches the second end of the lever member 51, but the abutment 521 and the second end are not in direct contact, in which the lever member 51 does not exert a force for urging the locking spring 31 to compress during the process of inserting the plug 3, and the locking spring 31 is pressed against the inner wall of the socket 41 (see fig. 1) under the pushing of the moving clamping mechanism 21 to be compressively deformed. In consideration of the fact that when the plug is plugged manually, an operator does not normally press the locking spring piece 31 when plugging, the locking spring piece 31 is automatically compressed in abutting connection with the socket 41 (see fig. 1), after the plug 3 is plugged to the bottom, the locking spring piece 31 rebounds and abuts against the inner wall of the socket 41 (see fig. 1) to generate a crisp sound, and the operator can judge whether the plug 3 is plugged in place according to the sound. The structure is arranged in a process of simulating artificial plug, so that the plug life test of the RJ45 module is completed. As the eccentric disc 252 continues to rotate, when the abutment position 2523 abuts against the extraction end, the whole process of extracting the plug 3 from the socket 41 is represented, in which the abutment portion 521 abuts against and presses down the second end of the lever member 51, and the first end of the lever member 51 abuts against and compresses the locking spring piece 31 due to the hinged arrangement of the lever member 51.
The two ends of the abutting portion 521 along the rotation direction thereof are provided with guide surfaces 522, and the guide surfaces 522 may be curved surfaces or inclined planes. When the plug 3 has been inserted into the socket 41 (see fig. 1), the driving assembly 22 drives the eccentric disc 252 to continue rotating, and the movable frame 251 and the plug 3 are in a stationary state until the protrusion 2522 abuts against the extracted end of the movable frame 251; however, in this process, as the eccentric disc 252 rotates, the guide surface 522 of the linkage 52 gradually approaches and abuts against the second end of the lever member 51, and the second end of the lever member 51 moves along the guide surface 522 to the lower end of the abutting portion 521, that is, the locking spring 31 is in a compressed state, so as to prepare for the subsequent disengagement of the plug 3 from the socket 41.
The lower end of the motion clamping mechanism 21 is welded with a horizontal limiting piece 27, the lower end of the horizontal limiting piece 27 is provided with a limiting groove 271 upwards, the limiting groove 271 penetrates through two ends of the horizontal limiting piece 27 along the length direction of the lever piece 51, the width of the lever piece 51 is the same as that of the limiting groove 271, namely two sides of the lever piece 51 are respectively abutted to two side walls of the limiting groove 271. When the eccentric disc 252 and the linkage member 52 rotate simultaneously, the linkage member 52 is in sliding contact with the second end of the lever member 51, and there is relative friction between the two, so that the second end of the lever member 51 will receive the friction force applied by the linkage member 52 in the horizontal direction, and the limiting groove 271 is used for avoiding the second end of the lever member 51 from horizontally shifting under the action of the friction force as much as possible. It is to be understood that the horizontal stopper 27 may be provided at the lower end of the movable frame 251 in addition to the lower end of the moving clamping mechanism 21.
In conjunction with the foregoing drawings, for ease of understanding, embodiments of the present invention provide a more specific implementation scenario. Before performing the RJ45 module plugging test, a worker firstly places the electronic product 4 to be tested on the support plate 131, and rotates the rotary handle 133 to adjust the placing height of the electronic product 4, so that the RJ45 socket 41 of the electronic product 4 and the plug 3 fixed on the moving clamping mechanism 21 are positioned at the same height; the electronic product 4 is moved to adjust the clamping position on the horizontal plane, one side of the electronic product 4 provided with the RJ45 socket 41 is abutted against the flexible pad 123 of the first group of positioning brackets 121, and then the first group of positioning brackets 121 are slid and fixed, so that the other side of the electronic product 4 is abutted against the flexible pad 123 of the second group of positioning brackets 121, and the clamping action of the electronic product 4 is completed.
When the plug test is performed, the motor 222 is started, and the motor 222 drives the eccentric disc 252 and the linkage member 52 to rotate together. When the eccentric disc 252 drives the movable frame 251 to gradually approach the electronic product 4, the linkage piece 52 rotates and gradually approaches the second end of the lever piece 51, and the plug 3 on the moving clamping mechanism 21 gradually inserts into the socket 41; after the plug 3 is inserted, the motor 222 drives the eccentric disc 252 to continue to rotate, and the movable frame 251 does not slide in the process that the arc edge of the protruding part 2522 is directly abutted against the first side 2511, so that the movable frame 251 is in a static state; in this process, the second end of the lever member 51 approaches and abuts against the guide surface 522 of the linkage member 52, and slides along the guide surface 522 to the abutting portion 521, that is, the second end of the lever member 51 gradually presses down, the first end of the lever member 51 gradually presses the locking spring 31 upward, and the locking spring 31 compresses and breaks away from the inner wall of the socket 41; as the eccentric disc 252 continues to rotate, the abutting position 2523 of the eccentric disc 252 abuts against the pulling end of the movable frame 251, the eccentric disc 252 starts to drive the movable frame 251 away from the electronic product 4, and the plug 3 is smoothly pulled out of the socket 41 due to the compressed state of the locking spring piece 31; as the eccentric disc 252 continues to rotate, the arc edge of the protrusion 2522 abuts against the extraction end of the movable frame 251, which indicates that the plug 3 has been extracted and the plug 3 and the moving clamping mechanism 21 are in a stationary state, in this process, the second end of the lever member 51 slides from the abutment 521 to the guiding surface 522 on the other side, so as to disengage from the linkage member 52 and rebound to the initial state, which is the process of the RJ45 module single insertion test.
