Description
Technical Field
The present disclosure relates to electrical connectors, and particularly to a method for manufacturing an electrical connector.
Background
Fig. 1 shows a conventional electrical connector 1' comprising a plurality of metal terminals 10' and an insulating body 20' for accommodating the terminals, wherein the terminals 10' are formed by punching and cutting a metal strip 100', and the metal strip 100' comprises a base portion 101' which is formed into scraps after punching and a cutting portion 102' for forming the terminals 10 '. The terminal 10' includes a protruding contact portion 11' and a connecting portion 12' connected to the contact portion, the contact portion 11' being close to the base portion 101'. The contact 11' requires an electro-plating solution to ensure better electrical contact. During the plating, since the contact portion 11' is close to the base portion 101', the base portion 101' is also plated with the gold solution. While the base 101 'is cut to form scrap when the terminal 10' is stamped and cut, this arrangement wastes a considerable amount of gold liquid. Greatly improves the production cost.
In addition, in production, the insulating body 20' is also located on the side close to the base 101' of the metal strip 100 '. A clamp (not shown) clamps the base 101', cuts the metal tape 100', and separates the terminal 10 'from the metal tape 100'. When the terminal 10' is inserted into the insulating body 20', the connecting portion 12' adjacent to the contact portion 11' is clamped by the clamp, and the insulating body 20' is positioned at one side adjacent to the base portion of the metal strip 100', that is, the clamping area of the clamp clamping the strip 100' and the area for clamping the terminal 10' are positioned at the same side as the direction of inserting the terminal 10', the clamp can interfere with the insulating body 20', and the clamping of the multi-follow terminal 10' into the insulating body cannot be realized in action. Only one can be cut and then one terminal 20' is clamped by the clamp to be inserted into the insulator body, so that the production efficiency is low.
Accordingly, there is a need to provide a new method of producing an electrical connector that solves such problems.

Detailed Description
In order to make the technical problems solved, the technical scheme adopted and the technical effects achieved by the invention more clear, the technical scheme of the invention is further described below by a specific embodiment in combination with the attached drawings.
As shown in fig. 2 to 4, the present embodiment provides a method for manufacturing an electrical connector 1, wherein the electrical connector 1 is used for plugging with a busbar (not shown).
Referring to fig. 2, in a first step, a metal tape 100 and a jig (not shown) on a production line are provided, wherein the metal tape 100 includes a base 101 and a cutting portion 102. The clamp is located on the side close to the base 101 of the metal strip 100, clamping the base 101.
As shown in fig. 3, in a second step, the cut portions 102 of the metal tape 100 are punched to form a plurality of terminals 10 connected together, each terminal 10 including a protruding contact portion 11, an opposite insertion portion 13, and a connection portion 12 connecting the opposite insertion portion 13 and the contact portion 11. The contact portion 11 of the terminal 10 is located at a side far away from the metal strip base 101 of the strip, and the opposite insertion portion 13 is close to the metal strip base 101, and the connection portions 12 of the adjacent terminals 10 are connected together. In addition, the connecting portion 12 of the terminal 10 is provided with a plurality of protruding interference portions 14. The inserting portion 13 is a portion to be inserted into the busbar (not shown).
Then, in a third step, the jig clamps the connection portions 12 of 6 terminals among the plurality of terminals.
Fourth, the metal strip 100 is punched and cut again, the terminals 10 are separated from the base 101 of the metal strip 100, and the adjacent terminals 10 are separated. After the terminal is punched and cut, the base 101 of the metal strip 100 becomes scrap.
Fifth, an insulating body 20 is provided, the insulating body 20 includes a receiving space 21 for receiving the terminals 10, the fixture simultaneously clamps the connection portions of the 6 terminals to be inserted into the receiving space 21 of the insulating body 20, and the interference portion 14 of the terminal 10 is in interference fit with the insulating body 20.
Wherein, since the contact portion 11 of the terminal 10 is located at a side far from the base portion 101 of the metal strip 100, the direction of inserting the terminal 10 into the insulating body 20 and the area where the clamp clamps the base portion 101 and the area where the clamp clamps the terminal are located at opposite sides, thus the clamp and the insulating body 20 do not interfere, and a plurality of terminals can be cut and clamped simultaneously. In the present embodiment, the number of plural pieces that can be cut and held simultaneously is 6.
Before the second step, in order to ensure good electrical contact performance of the contact portion 11 of the terminal 10, a gold liquid plating of the contact portion 11 of the terminal 10 is also provided, since the contact portion 11 of the terminal 10 is located at a side remote from the base portion 101 of the metal strip, the base portion of the metal strip 100 does not contact the gold liquid.
In the manufacturing method of the electrical connector provided by the invention, particularly in the arrangement mode of the terminals 10 on the metal strip 100 in the second step, the contact parts 11 of the terminals 10 are arranged to be positioned at one side far away from the base 101 of the metal strip 100, and during electroplating, the metal liquid cannot be electroplated to the base 101 (namely the waste area) of the metal strip 100, so that compared with the prior scheme, the metal liquid is greatly saved, and the cost is reduced; meanwhile, since the contact portion 11 of the terminal 10 is located at one side of the base portion 101 far away from the metal strip 100, the region where the base portion 101 is clamped by the clamp (not shown) and the region where the terminal is clamped are located at opposite sides from the direction in which the terminal 10 is inserted into the insulating body 20, the clamp and the insulating body 20 do not interfere, so that a plurality of terminals can be cut and clamped at the same time, and the production efficiency is improved.
The foregoing is merely exemplary of the present invention, and those skilled in the art should not be considered as limiting the invention, since modifications may be made in the specific embodiments and application scope of the invention in light of the teachings of the present invention.
