Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electrical connector having a structure capable of resisting a tensile force acting in a direction of separation when the electrical connectors are connected to each other.

Conventional electric wire connections are made by connecting male and female connectors connected to each of the wires together with a housing in which the connectors are installed, and the separation direction acting on the connected portions In order to resist the tensile force, there is mainly the holding force of a locking device called a lock that locks the couplers together, or the holding force of a connector separation preventer called a lance that locks the connector in the housing. It was common for the connector to separate if either of these holding forces were exceeded.

However, since the above-mentioned lance is simply formed by a claw piece cut and raised inside the connector or housing, the strength at that part is weak, and it can be easily broken by applying a slightly large tensile force to that part. However, the above-mentioned locked state had the disadvantage of collapsing.

In view of the above-mentioned drawbacks, the present application attempts to solve the above-mentioned drawbacks by directly latching the connectors to each other so that the above-mentioned tensile force is resisted by the latching force without being resisted by the holding force of a lance. It is something to do.

An example of the implementation of the present invention will be described below based on the drawings. Reference numeral 1 denotes an electrical connector main body provided with a wire connection portion 2, a male tab fitting contact portion 3, and a male tab 4, and the wire connection portion 2 is approximately U-shaped insulation barrel 5 and wire barrel 6
The male tab fitting contact part 3 is connected to the wire connection part 2 and has a slit 8 along the top end of the approximately U-shaped curved part 7, and a mating electrical connector is connected to the slit 8. The male tab 4 of the main body 1 is fitted into the main body 1.

The male tab 4 is connected to the male tab insertion contact portion 3, and has a substantially U-shaped curved portion 9, and extends parallel side walls 10 and 10' from the top end of the curved portion 9. The end portion is cut and raised by approximately 180°, and the tip portion is slightly narrowed from all sides to form a tapered portion 11 in this portion.

The male tab fitting contact part 3 slightly bends both side edges of the slit 8 outward to form a guide piece 12.12' in this part, and the distance between the base parts 13.13' of the guide pieces 12.12' is A is made to be approximately the same as the short width B in the cross-sectional shape of the male tab 4, and the interval between the side walls 14 and 14' standing side by side from the curved portion 7 is gradually narrowed toward the tip.

15 is a lance cut outward from the side wall 10', 16
．． 16' and 17.17' are the side walls 20, 20', 21. of the intermediate part 18 between the wire connection part 2 and the male tab fitting contact part 3, and the intermediate part 19 of the male tab fitting contact part 3 and the male tab 4, respectively. 2
1' It is a leg extending laterally from the tip.

As described above, the male tab fitting contact portion 3 has a side wall 14.1 in order to fit the male tab 4 of the mating electrical connector main body 1'.
4' is located inward from each of the adjacent side walls 20.20' and 21.21'.

The electrical connector main body 1 having the above-described structure is used by being housed in a housing 22 shown as an example in FIG. A slit 24 communicating with the terminal accommodating portion 23 is formed in the lower wall, and a protrusion 26 is provided in each of the side walls 25.
Engagement arms 27 that engage with the projections 26 are formed to hang downward from the front portion of the lower wall.

The electrical connector main body 1 has the male tab 4 protruding from the slit 24 with respect to the housing 22, and the lance 15 is engaged with a retaining part (not shown) provided in the terminal accommodating part 23,
The legs 20.20' and 21.21' are assembled by pressing against the inner wall of the terminal accommodating portion 23, and the opposing housings 22.22' engage the engaging arm 27 and the protrusion 26. When the electrical connector bodies 1 and 1' are mutually hugged and connected, the male tabs 4 fit into the male tab fitting contact portions 3 of the opposing electrical connector bodies 1 and 1', thereby establishing an electrical connection.

In short, the present invention includes an electrical connector main body 1, an electric wire connection part 2 having a substantially U-shaped cross section, and a male tab fitting contact part which is connected to the wire connection part 2 and has a slit 8 at the top end of a curved part 9. 3 and a male tab 4 that hangs down from the side wall 10 that is connected to the male tab fitting contact portion 3, so that the housing 22 as described above is formed.
When the male tabs 4 protrude perpendicularly to the direction of extension of the electric wires and are connected to each other, the male tabs 4 are opened in the direction perpendicular to the direction of extension of the electric wires in the opposing electrical connector body 1'. Because it is inserted into the male tab fitting contact part 3, the locking force of the lance is applied to the tensile force, unlike the conventional mechanism that connects the male and female terminals together in the direction of extension of the wire. Even without resisting, the electrical connector bodies 1, 1' can resist the tensile force by the mutual locking force, and as long as the tensile force is not greater than the crimping force of the wire connection part 2, the electrical connector bodies 1, 1' electrical connection is intact.

Further, as shown in FIG. 4A 90, the male tab 4 is inserted into the slit 8 while being guided and regulated by the guide pieces 12 and 12' of the male tab fitting contact portion 3, and is inserted into the slit 8 when connecting a conventional connector. This has great practical effects, such as being able to prevent straining and allowing the male tab 4 to be inserted into the male tab fitting contact portion 3 with a low insertion force.
