Abstract

The application relates to a connector, which comprises a circumferential positioning piece, a first shell and a second shell. The circumferential positioning piece at least comprises a positioning rod. The first shell is provided with two opposite ends, and the two ends of the first shell are communicated. The second housing has opposite ends, one of which is threadedly engaged with one end of the first housing. One of the second shell and the first shell is provided with a first surface and is provided with a concave position which is sunken relative to the first surface. The other of the second shell and the first shell is provided with a second surface and is movably connected with a positioning rod. Under the condition that the locating rod is axially inserted into the concave position, the circumferential relative angle between the first shell and the second shell is locked, so that the first shell and the second shell are prevented from rotating along the loose direction, the first shell and the second shell are respectively kept at the positions clung to the sealing piece, and external liquid is prevented from flowing into the connector through gaps of the first shell and the second shell.

Description

Connector with a plurality of connectors Technical Field The present application relates to the field of connection devices, and in particular, to a connector. Background A connector is a device for achieving electrical interfacing between different devices. The connector can improve the electrical butt joint operation efficiency between different devices, and is widely applied to the fields of automobiles, communication, consumer electronics, data processing, industrial machinery and the like. The connector generally includes a housing, an insulator, and conductive terminals. The insulating part and the conductive terminals are respectively arranged in the shell. To facilitate the assembly of the insulator and the conductive terminal, the housing is generally divided into two parts. The two parts of the housing are connected by screw threads. When the two parts of the shell are screwed in place, the sealing piece is abutted against the gap between the two parts, so that liquid is prevented from entering the connector from the gap between the two parts, and short-circuit contact between the conductive terminals inside due to the liquid is avoided. Then, during the use of the connector, the two parts of the housing may rotate in a releasing direction, so that the two sides of the sealing member cannot be respectively clung to the two parts of the housing, and there is a risk that liquid flows into the connector through the gap. Disclosure of utility model Accordingly, the present utility model provides a connector that solves or at least alleviates the above-mentioned technical problems. The present utility model provides a connector comprising: the circumferential positioning piece at least comprises a positioning rod; A first shell having two opposite ends, which are communicated with each other, and The device comprises a first shell, a second shell, a positioning rod, a first shell, a second shell and a positioning rod, wherein the first shell is provided with two opposite ends, one end of the second shell is in threaded fit with one end of the first shell, one of the second shell and the first shell is provided with a first surface and a concave position which is sunken relative to the first surface, the other one of the second shell and the first shell is provided with a second surface and is movably connected with the positioning rod, the positioning rod is provided with a contraction position and a free position relative to the other one of the second shell and the first shell under the action of elastic force, the positioning rod is protruded relative to the second surface in the free position, the first surface and the second surface are oppositely arranged along the axial direction, and when the second shell and the first shell reach a preset threaded fit depth, the concave position corresponds to the positioning rod along the circumferential direction, and the positioning rod in the free position is inserted into the concave position along the axial direction. When the second shell and the first shell reach a preset screw thread matching depth, the positioning rod reaches a position corresponding to the concave position in the circumferential direction, and the concave position provides an extending space for the positioning rod, so that the positioning rod is switched to a free position and is inserted into the concave position. Under the condition that the locating rod is axially inserted into the concave position, the circumferential relative angle between the first shell and the second shell is locked, so that the first shell and the second shell are prevented from rotating along the loose direction, the first shell and the second shell are respectively kept at the positions clung to the sealing piece, and external liquid is prevented from flowing into the connector through gaps of the first shell and the second shell. In one embodiment, the second housing and the first housing have a first boss portion protruding in a radial direction on an outer peripheral side thereof, and when the second housing and the first housing reach a predetermined screw fitting depth, one side of the first boss portion is opposite to the second surface in an axial direction, and the first surface and the recess are provided on one side of the first boss portion. In one embodiment, at least one edge region of one side of the first boss portion in the circumferential direction forms a curved surface or an inclined surface.
