Detailed ways

The split-type conductive terminal structure of the present invention will be described in detail below in conjunction with the accompanying drawings. Those skilled in the art should understand that the embodiments described below are only illustrative illustrations of the present utility model, and are not intended to limit it in any way. Throughout the drawings, the same or similar reference numerals denote the same or similar components.

FIG. 1 schematically shows a general structure (lead frame) of a split conductive terminal, including two sets of conductive terminal structures 1 and 2 . The two sets of conductive terminal structures 1 and 2 can be used together or separately as shown in FIG. 1 . The conductive terminal structure 1, 2 may include a plurality of conductive terminals, wherein each conductive terminal is a split type conductive terminal, including a conductive terminal body (or, it may be called a lead) 10 and a conductive terminal head connected to the conductive terminal body 10 Section 20. The conductive terminal head 20 is shown as a press-fit pin in FIG. 1 , but this is only exemplary, and it may also be a press-fit hole. In addition, as shown in FIG. 1 , the insertion directions of the conductive terminal heads 20 on different conductive terminals may be the same or opposite. Moreover, it can be understood that the insertion direction between the conductive terminal heads 20 on different conductive terminals may also form other angles (not shown).

In addition, although it is shown in FIG. 1 that each conductive terminal main body 10 is only provided with a split type conductive terminal head 20 at one end, and an integral structure at the other end, this is only exemplary, and the other end It is entirely possible to provide a split-type conductive terminal head 20 similarly.

The connection structure between the conductive terminal body 10 and the conductive terminal head 20 will be described in detail below with reference to FIGS. 2 and 3 .

It can be clearly seen from FIG. 2 and FIG. 3 that the conductive terminal head 20 is a linear structure extending in the insertion direction, and the conductive terminal body 10 has a section 11 extending in the same direction as the conductive terminal head 20 . The conductive terminal head 20 is fixedly connected (eg, welded, riveted, etc.) to the section 11 of the conductive terminal body 10 near the other end 202 opposite to the plugging end 201 , so as to be connected together. In an example of the present invention, welding bumps may be provided on the surface of the conductive terminal head 20 facing the section 11 of the conductive terminal body 10 , so as to weld the two together. The conductive terminal head 20 and the conductive terminal body 10 can also be connected in other fixed ways.

In the connection structure as described above, although the solder bumps will melt after welding (especially fusion welding), there is still a certain gap between the conductive terminal head 20 and the section 11 of the conductive terminal body 10 .

FIG. 4 is a partial schematic diagram of a connector using the split-type conductive terminal as shown in FIGS. 1-3 . The connector includes a connector housing 30 and the above-mentioned split conductive terminals disposed in the connector housing 30 , and the connector housing 30 is generally formed by injection molding.

It is pointed out here by the way that according to the specific application, the conductive terminal body 10 and the conductive terminal head 20 can be welded together before being set in the connector housing 30 (called first welding), or they can be placed in the connector housing 30 Welding is done afterward (called post-welding).

During the use of the connector, the conductive terminal head 20 undergoes a plugging motion, during which the frictional force between the mating terminal and the mating terminal will act against the soldering part, and other external forces perpendicular to the plugging direction will also adversely affect both. Solder connection between. In other words, in this split structure, it is difficult to guarantee the position of the conductive terminal head 20 . Once the connection between the two is cracked and separated from each other (especially in the left and right directions), the function of the entire connector will fail.

In order to overcome this defect, according to a preferred embodiment of the present invention, an improved split-type conductive terminal structure is proposed. It is generally similar to the connection structure described above with reference to FIGS. 1-3 , and the differences are mainly described below.

As shown in Figure 5, in the improved split-type conductive terminal structure, the conductive terminal head 20 is no longer a straight structure, but bent, which includes a first part 21 extending along the insertion direction and a second A part 21 forms an angled second part 22 , and a connection area 23 for connecting the conductive terminal head 20 to the conductive terminal body 10 is disposed in the second part 22 . Wherein, the angle between the second part 22 and the first part 21 of the conductive terminal head 20 is preferably 90 degrees.

Here, the connection area 23 of the conductive terminal head 20 overlaps with the conductive terminal main body 10, and the conductive terminal head 20 may be provided with a soldering bump 24 on the surface facing the conductive terminal main body 10 in the connection area 23. The conductive terminal head 20 is connected with the conductive terminal body 10 . Welding is preferably fusion welding, and may also be pressure welding.

Incidentally, the split conductive terminal main body 10 and the conductive terminal head 20 can be formed by stamping through a mold respectively.

It can be seen from FIG. 5 , especially compared with FIG. 2 , by changing the structure of the conductive terminal head 20, the connection position between the conductive terminal head 20 and the conductive terminal body 10 is changed from the section along the plugging direction Transfer to the section perpendicular to the plugging direction, and change the left and right welding fits shown in Figure 2 to the upper and lower welding fits shown in Figure 5. The benefits of this improvement are easier to understand from the connector shown in Figure 6.

In the connector shown in FIG. 6 , the conductive terminal head 20 and the connector housing 30 are integrally molded. For example, the first portion 21 on the conductive terminal head 20 is integrally molded with the connector housing 30 . Preferably, a part of each of the first part 21 and the second part 22 is integrally molded with the connector housing 30 .

It can be clearly seen from FIG. 6 that with the improved connection structure, both the first part 21 and the second part 22 of the conductive terminal head 20 can be held more firmly by the plastic shell 30, and the welding part is supported by the first part 21. The effect of the force is very small, which can significantly improve the reliability.

In the description of the present utility model, unless otherwise specified, the directional terms "up" and "down" and "left" and "right" are all for the illustrated positions.

Although the utility model has been specifically described above in conjunction with exemplary preferred embodiments, under the teaching of the utility model, those skilled in the art can make various changes, and all these modifications do not depart from the scope defined by the claims. The scope of the utility model.
