Description

Technical Field

[0001] The utility model is applied to the field of product fixtures, and particularly relates to a concave-convex ZIF connector pin removal fixture. Background Art

[0002] In the production process of electronic products, ensuring their quality is of paramount importance. The quality of electronic products directly affects their sales volume. Therefore, functional testing of electronic products is essential during the production process. Based on the design requirements, a fixture is designed that combines a ZIF connector with a linear motor and uses a pin assembly for pin insertion. ZIF connectors differ from traditional B2B connectors in that they are thin and small, making it very difficult to insert pins and overcome the stress of the cable to prevent it from jumping out. Currently, the most common ZIF connector connection method is a male-female socket type, where the male socket is inserted into the female socket to form a guide sleeve. This traditional connection method is very time-consuming and can easily lead to insufficient shipments or waste of manpower and material costs for products with large shipment volumes. It also has poor repeatability and a short lifespan for the male and female sockets. Based on the above issues, if a compact, highly repeatable, and concave-convex ZIF connector pin insertion fixture can be designed that is compatible with multiple ZIF connector products, it can effectively solve these problems.

It can be seen that the lower needle plate 60 supports the upper needle plate 61 and the needle element 63, and the needle element 63 connects the upper needle plate 61 and the circuit fixing plate 4 to transmit signals. The upper needle plate 61 is provided with the contoured groove 66, and the contoured groove 66 can closely cooperate with the ZIF connector 7, so that the test signal of the motor 3 to be tested is transmitted to the magnetic connector 5 through the needle element 63 and the circuit fixing plate 4, and the magnetic connector 5 is then cooperated with the external device and transmitted to the external device. The equal height screw 64 and the first spring 65 are provided between the lower needle plate 60 and the upper needle plate 60, so that when the lower needle plate 60 and the lower needle plate 60 are limited, they can also float slightly, so that the upper needle plate 61 will not be over-pressed when cooperating with the ZIF connector 7, and the first spring 65 plays the role of over-pressure protection of the ZIF connector 7.

[0026] like Figures 1 to 4 As shown, in this embodiment, the clamp body 1 is provided with a plurality of tapered holes 13 for positioning around it, and the tapered holes 13 cooperate with the external device.

[0030] like Figure 3 and Figure 7As shown, in this embodiment, a second magnet 16 is further provided on the first groove 10, and the second magnet 16 cooperates with the first magnet 82. Thus, the first groove 10 fixes and supports the second magnet 16, and the second magnet 16 and the first magnet 82 closely cooperate with each other magnetically, so that the intermediate voltage arm block 23 is limitedly engaged with the first groove 10. Furthermore, the use of magnet engagement has the characteristic of high repeatability.

The screw elements 99 act as limiters to ensure the stability of the clamp. At the same time, the screw elements 99 are low-cost and easy to replace and install.

[0032] In this embodiment, the working principle of the utility model is as follows:

[0033] like Figures 1 to 8 As shown, before placing the product, the operator removes the guide seat 26 from the fixture body 1, pulls out the guide rod 25, pushes the left pressure arm block 22, the right guide slider 21 and the middle pressure arm block 23 away from the middle position, and the operator limits the motor 3 to be tested on the fixture body 1 through the positioning pin 15. At the same time, the operator uses plastic tweezers to place the ZIF connector 7 on the needle block module. The operator pushes the left pressure arm block 22, the right guide slider 21 and the middle pressure arm block 23 in turn to limit the motor 3 to be tested and the ZIF connector 7, places the guide rod 25 into the left pressure arm block 22, the right guide slider 21 and the middle pressure arm block 23, and installs the guide seat 26.
