[0027] As Figure 1 shown, the present utility model discloses a mobile phone charger plug on-off test device 100, which includes a test bracket 10, a test device 30 and a test fixture 20. The test device 30 and the test fixture 20 are both arranged on the test bracket 10. The test fixture 20 is used to place and position a plurality of mobile phone chargers. The test device 30 is electrically connected to the plurality of mobile phone chargers through the test fixture 20, and then the test device 30 detects the plurality of mobile phone chargers.
[0028] Furthermore, the test bracket 10 is a frame formed by splicing a plurality of profiles. The test fixture 20 is arranged above the test device 30. Both the test fixture 20 and the test device 30 are connected to the test bracket 10. The test fixture 20 can move relative to the test bracket 10 to adjust the corresponding position to facilitate the corresponding cooperation between the test device 30 and the test fixture 20.
[0029] As Figure 2 and Figure 3 shown, the test fixture 20 includes a fixture bracket 21 and a fixture plate 22. A first electrical connection plate 23 is arranged below the fixture bracket 21. The fixture plate 22 is fixed on the upper surface of the fixture bracket 21. A plurality of adapters 221 are evenly distributed along the extending direction of the fixture plate 22. The adapters 221 are electrically connected to the first electrical connection plate 23. A placement groove 222 is arranged at the top of the adapter 221, and a jack 224 is arranged in the placement groove 222. The charger plug is arranged in the placement groove 222 and is electrically connected to the jack 224. Specifically, when testing a mobile phone charger, a plurality of mobile phone chargers are sequentially placed in the corresponding placement grooves 222, and then the plugs of the mobile phone chargers are inserted into the jacks 224, so that the mobile phone chargers are electrically connected to the adapters 221. The adapters 221 are provided with pins, and the pins are electrically connected to the first electrical connection plate 23. When the test device 30 contacts the first electrical connection plate 23, the test device 30 can be electrically connected to the mobile phone charger.
[0030] The test fixture 20 further includes a fixture housing 223. The fixture housing 223 is fixed above the fixture board 22. The placement groove 222 is provided on the fixture housing 223. The fixture housing 223 at least wraps the bottom position of the charger plug through the placement groove 222. When the mobile phone charger is placed in the fixture housing 223, the fixture housing 223 wraps the bottom end of the charger. At this time, an external force can be applied to the mobile phone charger so that the plug of the mobile phone charger is inserted into the jack 224. At this time, the fixture housing 223 can position the mobile phone charger.
[0031] As Figure 1 and Figure 4 shown, further, a pressing assembly 25 is also provided on the test device. The pressing assembly 25 includes a pressing bracket 251, a pressing cylinder 252 and a lower pressing plate 253. The pressing bracket 251 is fixedly connected to the test bracket 10. The lower pressing plate 253 is arranged directly above the fixture board 22. The pressing cylinder 252 can drive the lower pressing plate 253 to move in the vertical direction to press the plug into the placement groove 222. In this application, the length of the lower pressing plate 253 is the same as the length of the fixture board 22. After the mobile phone charger is placed in the fixture housing 223, the pressing cylinder 252 drives the lower pressing plate 253 to move downward. At this time, the lower pressing plate 253 can apply an external force to the mobile phone charger so that the mobile phone charger moves downward, and further the plug of the mobile phone charger is inserted into the jack 224 to electrically connect the mobile phone charger to the adapter 221.
[0032] An insulating film 254 is provided on the bottom surface of the lower pressing plate 253. The lower pressing plate 253 applies a downward pressure to the mobile phone charger through the insulating film 254, which can prevent the lower pressing plate 253 from damaging the mobile phone charger.
[0033] As Figure 5As shown, a first guide rail bracket 211 and a second guide rail bracket 212 are fixed on the jig bracket 21. The first guide rail bracket 211 and the second guide rail bracket 212 are arranged oppositely. A first support platform 213 is arranged on the first guide rail bracket 211, and a second support platform 214 is arranged on the second guide rail bracket 212. The jig plate 22 is arranged between the first guide rail bracket 211 and the second guide rail bracket 212. Both sides of the jig plate 22 are supported by the first support platform 213 and the second support platform 214 respectively. Further, a first pressing block 215 is arranged on the first guide rail bracket 211, and a second pressing block 217 is arranged on the second guide rail bracket 212. The first pressing block 215 includes a first pressing block protrusion 216, and the second pressing block 217 includes a second pressing block protrusion 218. The first pressing block protrusion 216 is located above the first support platform 213, and the second pressing block protrusion 218 is located above the second support platform 214. One side of the jig plate 22 is located between the first pressing block protrusion 216 and the first support platform 213, and the other side of the jig plate 22 is located between the second pressing block protrusion 218 and the second support platform 214. Specifically, after the jig plate 22 is placed on the first guide rail bracket 211 and the second guide rail bracket 212, an external force can be applied to the jig plate 22 to drive the jig plate 22 to move so as to adjust the position of the jig plate 22.
[0034] In this application, two positioning members can be arranged on the jig bracket 21. The two positioning members are respectively located at both ends of the jig plate 22. After the jig plate 22 moves to a preset position, the jig plate 22 can be positioned by the positioning members. Specifically, the positioning members can be detachable screws, and there is no specific limitation in this application.
[0035] As Figure 6 shown, further, a lifting cylinder 31 and a probe board 32 are arranged below the test bracket 10. A plurality of probes 33 are arranged on the probe board 32. The probes 33 are connected to the test device 30. The lifting cylinder 31 can drive the probe board 32 to move in the vertical direction to drive the probes 33 to be in electrical contact with the first electrical connection board 23.
[0036] As Figure 2 and Figure 6As shown, specifically, a plurality of contact holes 232 are provided on the first electrical connection plate 23. The contact holes 232 penetrate through the first electrical connection plate 23. An electrical connection piece 231 is attached to the top surface of the first electrical connection plate 23. The electrical connection piece 231 is electrically connected to the pin in the jack 224. The top end of the probe 33 passes through the contact hole 232 and is in electrical contact with the electrical connection piece 231. An installation bracket is provided on the test bracket 10. The probe board 32 is arranged above the installation bracket 311 and is slidably connected to the installation bracket. The lifting cylinder 31 is fixed to the installation bracket and can drive the probe board 32 to slide in the vertical direction. A positioning plate 34 is arranged above the probe board 32. The positioning plate 34 is connected to the probe board 32 through an elastic member. Through holes 35 corresponding to the contact holes 232 one by one are provided on the positioning plate 34. The top end of the probe 33 can pass through the through hole 35 and extend into the contact hole 232.
[0037] Specifically, when the lifting cylinder 31 drives the probe board 32 to move upward, it can synchronously drive the positioning plate 34 to move upward. When the positioning plate 34 contacts and fits the first electrical connection plate 23, the lifting cylinder 31 drives the probe board 32 to continue moving upward, so that the probe 33 passes through the through hole 35 until it extends into the contact hole 232, making the probe 33 electrically connected to the adapter 221. At this time, the test device 30 can be connected to the mobile phone charger.
[0038] In this application, the elastic member can be a return spring.
[0039] Without departing from the broad spirit and scope of the present utility model, it can be set into various embodiments and deformations. The above embodiments are used to illustrate the utility model, but do not limit the scope of the present utility model.
