Description

Follow-on bonder terminal pin

The utility model relates to a kind of terminal pin of connector, refers in particular to column pin that a kind of pin is one of the forming and follow-on bonder terminal pin of sheet pin.

The connector that general computer uses as shown in Figure 4, be equiped with a plurality of L type terminal b in the rear end of connector a, there is a column pin b1 below of this L type terminal b, and the perforation contact c1 that this column pin b1 can pass circuit board C is connected on the circuit in the mode of soldering.

But this mode with soldering is welded on mode on the circuit board c with the terminal b of connector a, makes that whole volume is bigger, can't reach the purpose of reduced volume.

The mode that a kind of surface adhering (SMD) arranged in addition is connected the pin of sheet on the contact of circuit board.As shown in Figure 5, be equiped with a plurality of Z-shaped terminal d in the rear end of connector a, the below of this Z-shaped terminal d is a sheet contact d1, and it can lean against on the surface contacts C2 of circuit board C, thereby this Z-shaped terminal C can be connected in the mode of surface adhering on the circuit board d.

Though be connected on the circuit board c sheet pin d1 of Z-shaped terminal d comparatively quick and convenient in the mode of surface adhering, but in the mode of surface adhering connector a is gone up Z-shaped terminal d adhesion in a row and be fixed on circuit board c when going up, if wherein the sheet pin d1 of certain part or several Z-shaped terminal d adhesion is fixing bad, will cause the situation of loose contact, and this connector a is contained in after circuit board c goes up in the mode of surface adhering, the reparation of can't adhering again again, be merely able to scrap, so manufacturing cost is higher.

The utility model is at above-mentioned defective, designs column pin that a kind of pin is one of the forming and follow-on bonder terminal pin of sheet pin.

Main purpose of the present utility model provides a kind of follow-on bonder terminal pin, can select the mode of soldering or surface adhering (SMD) that pin is connected on the circuit board during use.

For achieving the above object, the utility model adopts following technical proposals: its structure is: be provided with a plurality of sockets on a connector, in each this socket, be fitted with a terminal, the pin of this terminal rear end is connected on the circuit board, the pin of described terminal is integrally formed column pin and sheet pin, and this sheet pin is positioned at the side of this column pin; The perforation contact that this column pin can pass circuit board is fastened on the circuit board in the mode of soldering, and this sheet pin can lean against that the mode with surface adhering is connected on the circuit board on the surface contacts of circuit board.

After adopting technique scheme, because the pin of terminal has column pin and sheet pin, the column pin can directly pass the perforation contact of circuit board, the sheet pin can directly be pressed against on the surface contacts of circuit board, therefore can be earlier the sheet pin be connected on the surface contacts of circuit board in the mode of surface adhering, if the part terminal is arranged or when wherein some terminal causes loose contact because of surface adhering is bad, the column pin that can directly use pin instead is connected pin on the perforation contact of circuit board in the mode of soldering.Vice versa.So just can repair the terminal of loose contact, thereby improve the quality of product, reduce fraction defective.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the stereogram of follow-on bonder terminal pin of the present utility model;

Fig. 2 is the three-dimensional exploded view of follow-on bonder terminal pin of the present utility model;

Fig. 3 is the assembling view of follow-on bonder terminal pin of the present utility model;

The three-dimensional exploded view of the terminal pin of the connector that Fig. 4 is known;

Fig. 5 is the three-dimensional exploded view of the terminal pin of the known connector of another kind.

At first, see also Fig. 1 and Fig. 2, follow-on bonder terminal pin of the present utility model is to be provided with a plurality of sockets 11 on a connector 1, is fitted with a terminal 2 in this socket 11, and the pin 21 of the rear end of this terminal 2 is connected on the circuit board 3; This pin 21 is integrally formed column pin 21a and sheet pin 21b, and this sheet pin 21b is positioned at the side of column pin 21a; The perforation contact 31 that the column pin 21a of this pin 21 can pass circuit board 3 is fastened on the circuit board 3 in the mode of soldering, the sheet pin 21b of this pin 21 can lean against that the mode with surface adhering (SMD) is connected on the circuit board 3, as shown in Figure 3 on the surface contacts 32 of circuit board 3.

According to above-mentioned structure, because the pin 21 of this terminal 2 has column pin 21a and sheet pin 21b, this column pin 21a can directly pass the perforation contact 31 of circuit board 3, this sheet pin 21b can directly be pressed against on the surface contacts 32 of circuit board 3, therefore can be earlier sheet pin 21b be connected on the surface contacts 32 of circuit board 3 in the mode of surface adhering, if part terminal 2 is arranged or when wherein some terminal 2 causes loose contact because of surface adhering is bad, the column pin 21a that can directly use pin 21 instead is connected pin 21 on the perforation contact 31 of circuit board 3 in the mode of soldering, this perforation contact 31 and the same contact of surface contacts 32 sides, therefore can repair the terminal 2 of loose contact, thereby improve the quality of product, reduce fraction defective.

Otherwise, mode with welding is welded on the column pin 21a in the pin 21 on the perforation contact 31 of circuit board 3 earlier, when causing the situation of loose contact if some terminal 2 generation welding wherein are bad, can be again the sheet pin 21b in the pin 21 be connected on the surface contacts 32 of circuit board 3, reaches above-mentioned purpose equally in the mode of surface adhering.

The above only is a best specific embodiment of the present utility model, actual being not limited thereto, and all have identical or the variation person of the principle of equal effects, is all the protection range of this patent.
