Abstract
Description
Technical Field
[0001] The utility model relates to a shielding jig, in particular to a terminal electroplating shielding jig. Background Art
[0002] The terminals used in electrical connectors are mainly used for signal and power transmission. When the socket electrical connector and the plug electrical connector are inserted and positioned with each other, the terminals of each other will touch each other to conduct signal and power transmission. The touched part of the terminal is the effective area, and the area that does not touch and thus does not cause friction is called the ineffective area.
[0003] Generally, in order to improve the surface hardness and good conduction effect of the terminals, precious metals are electroplated on the surface of the terminals. These precious metals are costly. The current electroplating method is to soak all the terminals on the strip into the electroplating solution at one time, so that the whole terminal is soaked. Therefore, both the effective area and the ineffective area of the terminal are soaked in the electroplating solution. Usually, the effective area of the terminal is relatively smaller than the ineffective area. Therefore, when the number of terminals is more, the relative electroplating cost increases and the operation time also increases, thus increasing the overall cost of the connector. Summary of the Utility Model
[0004] A terminal electroplating shielding jig provided by the utility model aims to solve the above technical problems.
[0005] An embodiment of the utility model provides a terminal electroplating shielding jig, which mainly includes a base defining an accommodating operation space; a fixture disposed in the accommodating operation space, the fixture being composed of a first fixing member and a second fixing member, wherein a clamping space for clamping a terminal strip is defined between the first fixing member and the second fixing member, and a plurality of terminals connected to the terminal strip are disposed in a direction away from the fixture; and a plurality of adjusting members respectively disposed on the first fixing member and the second fixing member, and each adjusting member pivotally connects a height adjusting piece for synchronously moving the first fixing member and the second fixing member away from the first fixing member and the second fixing member.
[0006] Preferably, the height adjusting piece defines an adjusting space, and a plurality of adjusting nuts respectively screwed to the adjusting members are disposed in the adjusting space.
[0007] Preferably, each adjusting member defines a thread section for the adjusting nut to move up and down to drive the height adjusting piece and change the height of each terminal.
[0008] Preferably, the base is provided with a height marking piece for accurately adjusting the height of the fixture.
[0009] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:
[0010] 1. Balance the film thickness difference caused by the natural phenomenon of the high and low potential differences in electroplating, and play a role in saving the consumption of precious metals.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0016] Please refer to Figure 1 and Figure 2 as shown, which are a three-dimensional structural schematic diagram of the terminal electroplating shielding fixture of the present utility model and a schematic diagram of the use state of the height adjustment. The present utility model is a terminal electroplating shielding fixture. The fixture 1 mainly includes a base 10, a clamp 11, a plurality of adjusting pieces 12 and a height adjusting piece 13. The accommodating working space 100 of the base 10 is provided for the clamp 11. The clamp 11 is composed of a first fixing piece 110 and a second fixing piece 112. A clamping space 114 for clamping the terminal strip 2 is defined between the first fixing piece 110 and the second fixing piece 112. A plurality of terminals 20 connected to the terminal strip 2 are arranged in a direction away from the clamp 11. Each adjusting piece 12 is respectively arranged on the first fixing piece 110 and the second fixing piece 112. The height adjusting piece 13 pivotally connected to the first fixing piece 110 and the second fixing piece 112 at a position away from them can synchronously move the first fixing piece 110 and the second fixing piece 112.
[0017] The height adjusting piece 13 described above defines an adjusting space 130. A plurality of adjusting nuts 3 are arranged in the adjusting space 130 for respectively screwing onto each adjusting piece 12. Each adjusting piece 12 defines a thread section 120. The thread section 120 allows the adjusting nut 3 to move up and down to drive the height adjusting piece 13 and change the height of each terminal 20.
[0018] The aforementioned base 10 is provided with a height marking member 102, and different height scales are provided on the height marking member 102. Through the scales, the height of the fixture can be accurately adjusted according to terminals of different sizes. The adjustment method is to rotate each adjustment nut 3 provided in the adjustment space 130 of the height adjustment piece 13. The adjustment nut 3 moves up and down through the thread section 120 on the adjustment piece 12 to drive the height adjustment piece 13 and change the height of each terminal 20. Through the above method, the terminals can be fixed at the height to be electroplated. From Figure 2 it can be seen that during electroplating, the entire base 10 is located above the electroplating solution 4 (electroplating liquid surface), while the effective area 200 of the terminal 20 is located in the electroplating solution 4, and the ineffective area 202 is located above the electroplating solution 4 (electroplating liquid surface). As can be seen from the above, the fixture 1 in this case can effectively solve the problem of film thickness difference caused by the natural phenomenon of balancing the high and low potential differences during electroplating in the effective area of the terminal 20 (that is, the terminal contact area), playing a role in saving the consumption of precious metals. At the same time, by adjusting the height of the fixture, a shielding effect is achieved on terminals of different sizes, reducing the consumption of precious metals in the ineffective area and achieving the purpose of cost savings.
