Description

Technical Field

[0001] This utility model relates to the field of EOL testing equipment, and in particular to a switch module EOL testing fixture. Background Technology

[0002] Before automotive potentiometer switch modules roll off the production line, they undergo end-of-life (EOL) testing. Prior to EOL testing, a safe and reliable electrical connection must be established for the switch module under test. Current technology typically uses manual operation to load test probes onto the switch modules. Each switch module requires individual loading and unloading operations. Due to the repetitive and tedious process, and the influence of operator skill, the test probes and switch contacts cannot achieve instantaneous synchronous contact, leading to abnormal contact and interfering with the test results. This results in low efficiency on the final inspection line, unreliable test results, and an inability to meet production requirements. Utility Model Content

[0022] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] like Figure 1-5 As shown, the embodiments of this utility model include:

[0024] A switch module EOL testing fixture includes a connector template 1, a flip cover 2, side plates 3, a handle 4, and a support 5. The connector template 1 is provided with a flip cover 2. Side plates 3 are vertically arranged on both sides of the flip cover 2. A handle 4 is provided at the front of the side plates 3. A first roller 301 and a second roller 302 are arranged at the same height at the rear of the side plates 3. The support 5 is provided with a first interface 501 and a second interface 502 at the same height. The first roller 301 fits into the first interface 501, and the second roller 302 fits into the second interface 502. The first interface 501 is vertically provided with a shaft position control groove 501a, and the second interface 502 is vertically provided with a driven lifting groove 502a. A flipping guide groove 502b is provided extending from the top of the driven lifting groove 502a with the top end of the shaft position control groove 501a as the center.

[0025] The handle 4 is connected to the side plate 3 at its end shaft. The handle 4 is connected to a linkage control arm 6 next to the shaft. The linkage control arm 6 has a deflection line hole 601. The first roller shaft 301 is fitted into the deflection line hole 601.

[0026] Furthermore, the linkage control arm 6 is provided with a lifting and lowering guide pulley 602 parallel to the first roller shaft 301, and the support 5 is provided with a lifting and lowering guide groove 603. The lifting and lowering guide groove 603 is linearly constructed with a ramp 603a. The vertical component of the ramp 603a travels in accordance with the travel of the shaft position control groove 501a. The handle 4 causes the lifting cover 2 to rise and fall vertically along the shaft position control groove 501a with the first roller shaft 301 under the control of the lifting and lowering guide pulley 602.

[0027] Furthermore, the linkage control arm 6 is provided with a lifting guide pulley 604 parallel to the first roller shaft 301, and the support 5 is provided with a lifting guide groove 605. The lifting guide groove 605 is constructed with an arc-shaped slide 606. The arc-shaped slide 606 is centered on the top end of the shaft position control groove 501a. The handle 4, through the linkage control arm 6, causes the cover 2 to rotate and flip along the flipping guide groove 502b with the second roller shaft 302 under the control of the lifting guide pulley 604, with the top end of the shaft position control groove 501a as the center.

[0028] Furthermore, a limiting block 303 is provided on the side plate 3, and a clamping space is formed between the limiting block 303 and the side plate 3. The linkage control arm 6 is partially pressed into the clamping space by the limiting block 303 and close to the side plate 3.

[0029] Furthermore, the lifting guide groove 603 extends at the upper end of the ramp 603a and is provided with a clearance channel 603b that matches the lifting guide pulley 602.

[0030] Furthermore, the lifting guide groove 605 extends at the lower end of the arc-shaped slide 606 and is provided with a clearance channel 603b that matches the lifting guide pulley 604.

[0031] Furthermore, the outline of the linkage control arm 6 is provided with a guide notch 607, and the guide notch 607 has the same shape, size and distribution as the deflection line hole 601.

[0032] like Figure 1 As shown, the connector template 1 integrates an EOL test terminal. Before performing an EOL operation on the switch module, the switch module to be tested should be placed on the connector template 1, and then the flip cover 2 should be used to press the switch module to be tested in place. The bottom surface of the flip cover 2 is provided with a urethane pressure block, which acts on the switch module to be tested.

[0033] like Figure 6As shown, pressing down the handle 4 can move the lifting and lowering guide pulley 602 and the lifting guide pulley 604 clockwise. When the lifting and lowering guide pulley 602 touches the top of the avoidance channel 603b, the lifting guide pulley 604 can just reach the avoidance channel 603b, at which point the lifting cover 2 can reach the desired position. Figure 7 The horizontal position shown.

[0034] like Figure 7 As shown, at this time, the cover 2 and the connector template 1 are parallel to each other. Continuing to press down the handle 4 will cause the lifting pulley 604 to disengage from the avoidance channel 603b, and simultaneously cause the lowering pulley 602 to slide to the right along the ramp 603a. During the sliding process, the first roller 301 falls along the shaft position control groove 501a, and simultaneously, the second roller 302 falls synchronously along the driven lowering groove 502a. This process allows the cover 2 to press down on the test switch module in a horizontal state, ensuring that the test switch module and the EOL test terminal make synchronous and full contact.

[0035] like Figure 1 As shown in Figure 8, after being pressed down to the position, the handle retracts into the clamping guide groove 9. The clamping guide groove 9 is arc-shaped, with the axis of the handle 4 as the center. The entire clamping guide groove 9 is located on the support 5, which can realize the pulling and locking effect of the linkage control arm 6. That is, it can keep the lifting and lowering pulley 602 at the lowest end of the lifting and lowering guide groove 603, and suppress its retraction action under the elastic force of the urethane pressure block.

[0036] Figure 1 As shown, an electrical connector is also provided on the opposite side of the handle 4, that is, at the rear of the support 5. The electrical connector is electrically connected to the EOL test terminal. In the figure, the bottom of the connector template 1 is supported on two parallel linear rails, which can realize quick plugging and unplugging of the EOL test terminal and the electrical connector.

[0037] In summary, this utility model provides a switch module EOL testing fixture. Through the linkage between the support groove structure and the rollers and wheels, the linkage control arm can accurately control the lifting and lowering of the cover vertically and the flipping and lifting action, thereby realizing the synchronous batch electrical connection operation of the connector template to the switch module under test, improving the efficiency and reliability of EOL testing.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
