Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a loosening-proof connector. Background Art

[0002] A connector is also often referred to as a circuit connector or an electrical connector, which can be used to bridge two electrical components on a circuit, so that current or signals can flow from one electrical component to another. Since connectors are easy to be made into standardized components and have high electrical connection reliability, they are particularly suitable for modular components.

[0003] In the related art, a connector usually realizes electrical connection by plugging and connecting a wire-end component (connector male head) and a board-end component (connector female seat). Among them, the board-end component is provided with a slot, and conductive terminals are arranged in the slot. The wire-end component is provided with an extending end, and a contact terminal is arranged at the end of the extending end. The extending end is inserted into the slot, and the conductive terminal and the contact terminal are in contact and cooperate through locking by a buckle or a snap. Since the connection methods such as buckles and snaps have low manufacturing precision, and in order to avoid difficult installation, there is usually a certain tolerance space between the mutually cooperating buckles, which results in a certain movement space between the installed board-end component and the wire-end component. Such a structure easily causes the mutually contacting conductive terminals and contact terminals to move relative to each other or even separate from each other, resulting in poor contact. Therefore, how to ensure that the wire-end housing and the board-end housing can be accurately matched and will not move relative to each other under the condition of smooth installation has become an urgent problem to be solved. Summary of the Utility Model

[0006] In one embodiment, along the direction in which the protruding end is inserted into the mounting groove, the first friction boss is connected to the inner wall of the mounting groove through a first friction inclined surface, a first friction flat surface, and a first smooth inclined surface that are connected in sequence.

[0007] In one embodiment, in the direction in which the insertion plate is inserted into the insertion slot, the second friction boss includes a second friction inclined surface, a second friction flat surface, and a second smooth inclined surface that are connected in sequence.

[0008] In one embodiment, one end of the elastic arm includes a clamping protrusion, and the clamping protrusion is used for clamping into the positioning card hole.

[0009] In one embodiment, the anti-loosening connector further includes: an anti-fooling track, which is arranged between the board-end housing and the outer wall of the protruding end along the insertion direction of the protruding end.

[0010] In one embodiment, the wire-end housing includes a limiting baffle, and the limiting baffle corresponds to the connection position of the insertion plate and the elastic arm. The limiting baffle is used for restricting the elastic connecting piece from moving in the front-rear direction.

[0011] In one embodiment, the board-end housing is provided with a terminal mounting hole, and the board-end conductive terminal is inserted into the terminal mounting hole; a barb is arranged on the outer wall of the board-end conductive terminal, and the barb is used for restricting the board-end conductive terminal from detaching from the terminal mounting hole.

[0012] In one embodiment, the wire-end housing includes: a main body, the contact terminal is inserted into the main body in the front-rear direction; a wire harness mounting seat, which is inserted into the rear side of the main body; the wire harness mounting seat is provided with a wire harness jack corresponding to the contact terminal in a direction perpendicular to the insertion direction of the contact terminal, and the rear end of the contact terminal penetrates into the wire harness jack and is vertically inserted into the connected wire harness.

[0013] In one embodiment, a plurality of convex columns are arranged on both the upper and lower surfaces of the main body. The wire harness mounting seat includes oppositely arranged clamping plates, and the inner walls of the clamping plates are provided with fitting holes corresponding to the plurality of convex columns. When the wire harness mounting seat is inserted into the rear side of the main body, the clamping plates clamp the main body in the up-down direction, and the plurality of convex columns are in one-to-one correspondence and clamped with the fitting holes.

[0014] In one embodiment, a sliding groove is arranged on the side wall of the wire harness mounting seat in the direction of inserting the main body, and a guiding slider is arranged on the main body corresponding to the sliding groove. The wire harness mounting seat is inserted into the main body along the guiding slider.

[0015] In one embodiment, a rib is arranged on the inner wall surface of the lower end of the board-end housing along the insertion direction of the protruding end. The rib enables the protruding end to cooperate with the mounting groove to reduce shaking.

[0016] The above anti-loosening connector has at least the following beneficial effects:

[0017] By providing an installation groove on the board-end housing and providing first friction bosses and positioning card holes on the inner wall of the installation groove, and providing a first groove on the protruding end of the wire-end assembly, when the protruding end of the wire-end is inserted into the board-end housing, the first friction bosses contact the protruding end to generate frictional force to slowly insert the protruding end into the board-end housing. When the first friction bosses reach the first groove and snap into the first groove, the frictional force between the first friction bosses and the protruding end disappears, indicating that the protruding end and the board-end housing are plugged in place. Due to the existence of the first friction bosses, when there is a tendency for the protruding end and the board-end housing to be misaligned in a vibrating environment, the first friction bosses tend to disengage from the first groove. At this time, a frictional force is generated between the first friction bosses and the notch of the first groove to prevent the first friction bosses from disengaging from the first groove. Therefore, the accurate plugging and fixing of the board-end housing and the protruding end of the wire-end can be ensured. A positioning card hole is provided on the board-end housing, and a slot is provided on the protruding end of the wire-end. One end of an elastic connecting piece is snapped into the positioning card hole, and the other end is inserted into the slot to achieve secondary fixed connection. At the same time, a second friction boss is provided in the slot to limit the position fixing of the elastic connecting piece and the protruding end, and finally ensure the stable connection between the board-end assembly and the wire-end assembly.
