Description

Technical Field

[0001] The present invention belongs to the technical field of electrical connectors, and particularly relates to a multi-interface electrical connector structure with adjustable spacing. Background Art

[0002] In the wide application scenarios of modern electronic devices, as a key component for realizing electrical connection, the performance of electrical connectors directly affects the normal operation and user experience of the devices.

[0003] Traditional multi-interface electrical connectors usually have fixed interface spacing and angles, and the sizes of some connectors in the prior art are different. The fixed-spacing electrical interfaces often cause some plugs to be unable to be inserted smoothly, or poor contact or even damage to the interfaces due to crowded space after forced insertion. In addition, the electrical interfaces on existing electrical connectors are generally of an open design. During daily use, the electrical interfaces are extremely vulnerable to factors such as dust, water vapor, and external force collision, thus accelerating their aging and damage and reducing the reliability and stability of the connection. Therefore, a multi-interface electrical connector structure with adjustable spacing is designed to overcome the above technical defects. Summary of the Invention

[0004] (1) Technical Problems to be Solved

[0005] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a multi-interface electrical connector structure with adjustable spacing to solve the technical problems of inconvenient plugging and insufficient protection in the prior art as mentioned above.

[0006] (2) Technical Solutions

[0007] To solve the above technical problems, the present invention provides such a multi-interface electrical connector structure with adjustable spacing, which includes a housing. There are two housings and several side housings are arranged between them. Through grooves are opened on the front and rear side walls of the housing and the side housings. Electrical interfaces and protection components are installed at the through grooves. A circular tube and a horizontal tube are arranged between adjacent housings and side housings. A connecting tube fixedly connected to the circular tube is arranged inside the horizontal tube, and a multi-angle positioning component is arranged on the connecting tube.

[0008] Preferably, the protection component includes a protection plate. The protection plate is convexly arranged and a circular shaft is fixedly connected to the lower side. The circular shaft is movably connected to the housing and the side housing respectively. Two first springs are symmetrically sleeved on the circular shaft. The two ends of the first spring are fixedly connected to the side wall of the through groove and the side wall of the protection plate respectively.

[0009] Preferably, the multi-angle positioning component includes a fixed tube. A plurality of fixed tubes are evenly distributed and fixedly connected to the side wall at one end of the inner cavity of the transverse tube. A positioning rod is movably connected in each fixed tube. One end of the positioning rod in the inner cavity of the fixed tube is fixedly connected with a second spring, and the other end of the second spring is fixedly connected to the inner wall of the fixed tube. A plurality of positioning grooves are evenly distributed on the inner side wall of the transverse tube, and one end of the positioning rod away from the second spring is inserted into the positioning groove.

[0010] Furthermore, a side groove is formed on the side wall of the protective plate away from the electrical interface, and the side groove is arranged in an inverted L shape.

[0011] Furthermore, one end of the positioning rod away from the second spring is conical, and the positioning groove and the positioning rod are matched with each other.

[0012] Furthermore, the inner diameter of the circular tube is equal to the outer diameter of the transverse tube, the inner diameter of the transverse tube is larger than the outer diameter of the connecting tube, and the circular tube, the transverse tube and the connecting tube are concentrically arranged.

[0013] Furthermore, the circular tube, the transverse tube and the connecting tube are in a through-through arrangement, and an inlet opening is formed on the side wall of the left housing.

[0014] (3) Beneficial effects

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. When the electrical interface is not in use, by the elastic force of the first spring, the protective plate can be rotated into the through groove, and the through groove is blocked by the protective plate, reducing the influence or damage of external dust or impact on the electrical interface, effectively improving the protection of the electrical interface.

[0017] 2. By pulling the housing or the side shell, at this time the transverse tube moves in the circular tube, changing the distance between adjacent housings and side shells, and between adjacent two side shells, and the housing or the side shell can be rotationally adjusted. At this time, the positioning rod is pushed by the second spring, so that the positioning rod is inserted into the positioning groove on the inner wall of the transverse tube, realizing the positioning between the connecting tube and the transverse tube, that is, realizing the positioning of the housing and the side shell, so as to meet the connection needs of different connectors, with good adaptability.

The circular tube 6, the horizontal tube 7 and the connecting tube 8 are concentrically arranged. Through the concentric arrangement between the circular tube 6, the horizontal tube 7 and the connecting tube 8, the rotation adjustment function can be conveniently realized and it is convenient to use.
