Description

Technical Field

[0001] The invention belongs to the field of power-on testing of pin-type power-on products, and in particular relates to a power-on device for testing pin-type power-on modules. Background Art

[0002] Pin-type powered products are powered by directly welding the leads to the pins during installation and use by the user. However, during the power-on test in the production process, no damage to the appearance can be caused and there can be no traces of welding on the pins. Therefore, welding the leads to the pins for powering is not allowed. Moreover, for mass-produced pin-type powered products, it is not realistic to weld the leads one by one for power-on testing.

[0003] Currently, when power-on tests are performed on pin-type powered products, alligator clips are usually used to hold the pins for power-on testing. However, this method is inconvenient to operate and takes up a large amount of space when used in large-volume product testing. It is also prone to power-on staggered operation, resulting in device damage or unclear data correspondence. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a power-on device for testing a pin-type power-on module, including a pressure block, a power-on spring, a base, a rotating shaft, and a double torsion spring. The pressure block is connected to the base through a rotating shaft, a double torsion spring is provided at the rear end of the base, the power-on spring is placed at the front end of the base, the pressure block is covered on the double torsion spring, and the front end of the pressure block is pressed on the power-on spring.

[0005] Furthermore, a raised rib is provided at the front end of the base with a notch in the middle of the rib, a raised block is provided at the rear end of the base, the upper surface of the block is inclined, and a raised baffle is provided at the left and right ends of the base near the rear end of the base, and a first shaft hole is provided on the baffle.

[0006] Furthermore, notches are provided at the front and rear ends of the pressing block, and a second shaft hole is provided between the two notches to connect the left and right ends of the pressing block. The second shaft hole matches the first shaft hole on the base baffle, and the rotating shaft passes through the first shaft hole and the second shaft hole to connect the pressing block and the base, and a first through hole and a second through hole are provided at the bottom of the pressing block near the front end.

[0007] Furthermore, the middle of the powered spring is bent, the front end of the powered spring is higher than the rear end, the front end of the powered spring is placed on the raised strips on both sides of the front end notch of the base, and the two sides of the front end notch of the pressing block press the front end of the powered spring.

[0008] Furthermore, the double torsion spring is fixed on the upper surface of the object block protruding from the rear end of the base, the torsion bar of the double torsion spring is parallel to the base, and the bottom of the pressure block connected in the middle is parallel to the torsion bar.

[0009] Furthermore, a first countersunk hole and a second countersunk hole are provided at the bottom of the base. The first countersunk hole is close to the middle gap of the raised ribs at the front end of the base. Threaded holes and wire holes are provided at the same positions on the left and right sides of the second countersunk hole. The threaded holes are close to the front end of the base.

[0010] Furthermore, a high temperature wire is welded to the rear end of the power-on spring. During power-on testing, the high temperature wire passes through a wire hole at the bottom of the base and is connected to a power source.

[0011] Furthermore, when performing a power-on test, downward force is applied to the rear end of the pressure block, and the pressure block rotates downward around the rotating axis. The rear end of the pressure block compresses the double torsion spring to loosen the power-on spring at the front end of the pressure block. The power-on spring is lifted up with the help of its own elasticity, and the lead pin of the lead pin type product is extended under the power-on spring to achieve the connection between the lead pin and the power-on spring.

[0023] Specifically, a screw hole is provided at the rear end of the powered spring clip near the middle bending portion, and a high-temperature wire is welded at the rear end of the powered spring clip. This embodiment uses two powered spring clips.

[0024] Preferably, if Figure 1 As shown, a first countersunk hole and a second countersunk hole are arranged vertically front to back in the middle portion of the bottom of the base, the first countersunk hole is close to the middle notch of the raised rib at the front end of the base, and threaded holes and wire holes are provided at the same position on the left and right sides of the second countersunk hole, and the threaded holes are close to the front end of the base.

[0025] Specifically, the base is fixed to the base plate through the first countersunk hole and the second countersunk hole, and the screws pass through the screw holes of the power-on spring clip and the threaded holes on the base to fix the power-on spring clip on the base.

[0026] Specifically, the double torsion spring is fixed on the inclined surface of the object block protruding from the rear end of the base, the torsion bar of the double torsion spring is parallel to the base, and the bottom of the pressing block is parallel to the torsion bar.

[0027] In one embodiment, when performing a power-on test, Figure 2As shown, downward pressure is applied to the rear end of the pressing block, and the pressing block rotates downward around the rotating axis. The rear end of the pressing block compresses the double torsion spring arranged at the rear end of the base to loosen the powered spring at the front end of the pressing block.
