Description

Technical Field

[0001] The utility model relates to the technical field of mobile phone testing, in particular to a mobile phone electrical testing fixture. Background Art

[0002] Mobile phone batteries are energy storage tools that provide power for mobile phones. They are composed of three parts: battery cells, protection circuits, and shells. Mobile phone batteries generally use lithium batteries and nickel-metal hydride batteries. A fixture is a large category of tools for carpentry, ironwork, fitter, machinery, electronic control, and some other handicrafts. It is mainly used as a tool to assist in controlling position or movement. When testing mobile phone batteries, you need to use a fixture to fix the battery, and use a test probe to insert it into the port connection of the battery for testing. When conventional fixtures are used to clamp and fix mobile phone batteries, the fixture clamping mechanism needs to be adjusted according to the shape of the battery.

[0003] However, the existing clamping mechanism has a limited adjustment range when adjusting, so when clamping batteries of different sizes during testing, the clamping is limited and the batteries are not easy to take out after clamping, which affects the unloading of the batteries after testing and causes the batteries to be stuck on the fixture, making it inconvenient to take out. Utility Model Content

[0004] The purpose of the utility model is to provide a mobile phone electrical testing fixture to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0010] According to a further technical solution, protective pads are provided on the side walls of the extension plate and the clamping plate.

[0011] Beneficial effects of the utility model:

[0012] When the utility model is used to fix and limit the position of the battery, after the battery is horizontally placed in the placement groove, the rotating disk is rotated to drive the limit screw to rotate on the fixture plate, thereby driving the position of the clamping plate to move. By moving the position of the clamping plate in the sliding groove, the battery will be pressed against the placement groove without position deviation and movement, which will affect the accuracy of subsequent tests.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] Please refer to Figure 1-5 As shown; the utility model provides a technical solution: a mobile phone electrical testing fixture, including a fixture plate 1, the fixture plate 1 is provided with two symmetrically arranged placement slots 11, one side end of each placement slot 11 is provided with a battery clamping structure 2, the battery clamping structure 2 is slidably matched with the bottom of the placement slot 11, the battery clamping structure 2 is threadedly connected to the fixture plate 1, and the bottom of each placement slot 11 is provided with an upward ejection structure 3, the upward ejection structure 3 can drive the battery in the placement slot 11 to be ejected upward. With two placement slots 11, two batteries can be tested simultaneously during testing, which improves work efficiency.

[0023] During use, the mobile phone battery is placed in the placement groove 11 in the fixture plate 1, and then the position of the placed battery is clamped and fixed by the battery clamping structure 2 to prevent the battery position from moving during use, causing inaccurate testing. During the clamping process, the battery clamping position and distance can be adjusted in real time according to the different battery sizes, so as to clamp batteries of different sizes, thereby improving the applicability of battery clamping. After the battery test is completed, the horizontally placed battery can be lifted upward by the upward ejection structure 3, so that the tester can take and unload the battery.

[0024] In this embodiment, refer to Figure 3 and Figure 4As shown, the battery clamping structure 2 includes a limiting screw 21, and the limiting screw 21 is horizontally threadedly connected to the jig plate 1. A rotating disk 22 is provided at one end of the limiting screw 21, and a clamping plate 23 is provided at the other end of the limiting screw 21. The limiting screw 21 is rotatably connected to the clamping plate 23, and the clamping plate 23 is slidably matched with the placement groove 11; two extension plates 24 are provided on the clamping plate 23, and a plurality of connecting grooves 25 are provided on the clamping plate 23. A plurality of plug-in blocks 26 are provided on one side of the extension plate 24, and a plurality of plug-in grooves 27 are provided on the other side of the extension plate 24. The extension plate 24 is plugged into the plurality of connecting grooves 25 through the plurality of plug-in blocks 26, and the plug-in blocks 26 on adjacent extension plates 24 are plugged into the plug-in grooves 27. The clamping plate 23 is arranged in a frame shape, and the battery can be framed and limited.

[0025] When the position of the battery is fixed and limited, after the battery is horizontally placed in the placement groove 11, the rotating disk 22 is rotated to drive the limiting screw 21 to rotate on the fixture plate 1, thereby driving the position of the clamping plate 23 to move. By moving the position of the clamping plate 23 in the sliding groove, the battery will be pressed against the placement groove 11 without position deviation and movement, which will affect the accuracy of subsequent tests;

[0026] During use, the rotation range of the limit screw 21 is limited. When a small-sized battery needs to be tested and fixed, the extension plate 24 can be plugged into the connecting groove 25 on the clamping plate 23 through the plug-in block 26 to achieve the limit fixation between the clamping plate 23 and the extension plate 24, and the clamping plate 23 can be lengthened to better limit and fix the battery. Different numbers of extension plates 24 can be added according to the different sizes of the batteries, so that the extension plates 24 are located next to the tested battery, and the battery is limited in the placement groove 11 without position displacement and movement. The number of extension plates 24 can be better adjusted according to the needs of the battery size, and it can be suitable for testing batteries of different sizes during use.

[0027] In this embodiment, refer to Figure 5As shown, the upward ejection structure 3 includes an ejection inclined block 31 and an ejection rod 32, the ejection inclined block 31 is slidably connected in the jig plate 1, and a sliding rod 33 is provided on the ejection inclined block 31. The end of the sliding rod 33 extending outside the jig plate 1 is provided with a button 34, and the sliding rod 33 is provided with a reset spring 35 connected to the jig plate 1. During the use of the reset spring 35, when the ejection rod 32 is pushed upward to release the button 34, the ejection inclined block 31 will be returned to the initial state by the reset force of the reset spring 35, so as to eject the battery next time, the sliding rod 33 is slidably matched with the jig plate 1, and the ejection rod 32 is horizontally slidably connected in the placement groove 11, and the bottom of the ejection rod 32 is slidably matched with the inclined surface of the ejection inclined block 31, and the bottom of the ejection rod 32 is circular.

[0028] When lifting and unloading the battery, pressing the button 34 causes the slide bar 33 to move horizontally in the jig plate 1, thereby driving the position of the ejection bevel block 31 to move. After the inclined surface of the ejection bevel block 31 contacts the bottom of the ejection rod 32, it squeezes the ejection rod 32 to move upward. The upward movement of the ejection rod 32 causes the horizontally placed battery to move upward, making it convenient for subsequent testers to take the battery out of the placement slot 11 and unload the material, without causing the battery to be stuck in the placement slot 11 and difficult to remove.

[0029] In this embodiment, protective pads are provided on the side walls of the extension plate 24 and the clamping plate 23; the protective pads are wrapped around the extension plate 24 and the clamping plate 23, and when the battery is clamped and fixed, the outer wall of the battery can be protected without causing damage to the battery.
