[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figs. 1 to 3This utility model provides a technical solution: a stable USB connector, including a housing 1 and a connector 2. The connector 2 is detachably disposed in the housing 1. After the housing 1 and the connector 2 are assembled, they can form a connector to connect to a device with a USB interface. The connector 2 has a fixing groove 12 and a limiting groove 14. The housing 1 has a pressure groove 7. A pressure plate 8 is bent in the pressure groove 7 with the bending direction of the pressure plate 8 downward. A limiting plate 10 is bent in the housing 1 with the bending direction of the limiting plate 10 upward. After the housing 1 and the connector 2 are assembled, the pressure plate 8 and the limiting plate 10 can be inserted into the fixing groove 12 and the limiting groove 14 respectively after bending, so as to achieve a stable connection between the housing 1 and the connector 2. The connection points are at the top and the bottom, with two points.
[0017] The housing 1 has a connecting hole 6 for inserting the connector 2. The connector 2 has a guide groove 11 that can cooperate with the pressure plate 8. After the pressure plate 8 is bent, it will fall into the connecting hole 6. As the connector 2 is inserted into the housing 1, the pressure plate 8 will slide in the guide groove 11 until the housing 1 and the connector 2 are fixed. The guide groove 11 has the function of positioning and guiding the pressure plate 8, so that the connector 2 can be accurately inserted into the connecting hole 6.
[0018] The connecting body 2 includes a connecting seat 3, a connecting piece 4 is fixedly connected to the connecting seat 3, a pin 5 is provided in the connecting piece 4, a positioning block 13 is fixedly connected to the connecting piece 4, and a positioning groove 9 that cooperates with the positioning block 13 is provided on the housing 1. After the connecting seat 3 is inserted into the connecting hole 6, the positioning block 13 will be inserted into the positioning groove 9 and will be flush with the positioning groove 9 after being inserted into the positioning groove 9.
[0019] Among them, the guide groove 11, the fixing groove 12 and the positioning block 13 are all provided on the connecting seat 3. The connecting seat 3 can be inserted into the connecting hole 6. After the connecting seat 3 is inserted into the connecting hole 6, it will be accurately positioned in the connecting hole 6 through the cooperation of the positioning block 13 and the positioning groove 9.
[0020] Before the connector 2 is inserted into the housing 1, the pressure plate 8 is bent and positioned by the cooperation of the pressure plate 8 and the guide groove 11. After the connector 2 is inserted into the housing 1, the limiting plate 10 is bent so that the limiting plate 10 is inserted into the limiting groove 14.
[0021] Specifically, before installation between the housing 1 and the connector 2, the pressure plate 8 can be bent first. After the connector 3 is inserted into the connector hole 6, the connector 4 will be installed in the housing 1. Then, the pressure plate 8 will be positioned by the guide groove 11. As the connector 3 extends into the housing, the pressure plate 8 touches the inclined surface in the guide groove 11 and will be lifted by the inclined surface in the guide groove 11. The connector 3 will continue to extend into the connector hole 6. Then, the pressure plate 8 will spring back and fall into the fixing groove 12, abutting against the inner wall of the fixing groove 12. At the same time, the positioning block 13 will be inserted into the positioning groove 9, and the limiting plate 10 will be aligned with the position of the limiting groove 14. At this time, the limiting plate 10 can be bent upward so that the limiting plate 10 is inserted into the limiting groove 14, thus realizing the connection between the connector 2 and the housing 1.
