Description

Technical Field

[0001] This utility model relates to electrical transmission devices, and in particular to wiring harness sockets used in automobiles. Background Technology

[0002] Various wiring harness connectors are installed on the sheet metal surfaces of car bodies or doors. For example, the panel-mount connector disclosed in Chinese patent document CN116918195A has a cavity in the terminal housing for inserting terminals. The inner wall of the terminal cavity is provided with a flexural, spear-shaped part that locks the terminal. The locking function of the spear-shaped part relies on its own flexural deformation. If the flexural deformation fails or slips, the locking of the terminal will fail, the electrical connection of the terminal will be broken, and the electrical connection of the connector will be affected. Furthermore, since the spear-shaped part is integrally formed with the terminal cavity, if one of the spear-shaped parts fails, the entire connector will be scrapped. Summary of the Invention

[0003] In order to overcome the defect of the prior art that the terminal cavity fails due to flexural deformation and thus causes the terminal to break, this utility model proposes a panel-mounted wire harness socket with a special locking component for lateral locking of the terminal to improve the stability of locking the terminal.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a panel-mounted wire harness socket, comprising a housing and a terminal cavity provided in the housing for inserting terminals, wherein the housing has a through groove communicating with the terminal cavity, the through groove being perpendicular to and intersecting the terminal cavity; a locking member for locking the terminals is inserted into the through groove.

[0005] Furthermore, a cylinder for assembling a locking component is provided around the terminal cavity; the locking component has a crossbar and a crossbar for locking the terminal, the crossbar is provided with a hook and the hook is engaged with the inner side of the cylinder.

[0006] Furthermore, a cylinder for assembling a locking component is provided around the terminal cavity, and a bracket is provided on the inner side of the cylinder; the locking component has a crossbar and a crossbar for locking the terminal, and the crossbar is provided with a hook that is snapped into the bracket.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: Since a locking member is inserted into the transverse through groove of the housing, and the through groove connects to the terminal cavity, the locking member is horizontally snapped into the positioning position of the terminal in the terminal cavity, thereby locking the terminal. Compared with the prior art, an independent part is used to replace the spear-shaped part of the prior art. The force of the locking member positioning the terminal is a rigid force, and the socket will not lose the terminal locking function due to the failure of the flexural deformation of the spear-shaped part. This eliminates the phenomenon of terminal loosening, improves the stability of the locking terminal, and thus improves the electrical transmission stability of the socket terminal.

[0014] To better understand the purpose, features, and advantages of this utility model, the following description, in conjunction with the accompanying drawings and embodiments, will further illustrate this utility model.

[0015] Panel-mount wire harness connectors consist of a socket and a plug, such as... Figure 1 As shown, the panel-mounted wire harness socket 100 is mounted to the sheet metal surface C by bolts, and the wire harness is led out from the terminals in the socket.

[0016] like Figure 2 and Figure 3As shown, the panel-mounted wiring harness socket 100 consists of a housing 1 and a pair of locking members 2. The housing 1 is integrally formed from a base 1.1, a cylinder 1.2, a square cover 1.3, a flange 1.4, and a terminal portion 1.5. The base is circular and passes through the sheet metal surface C and is fitted with the mounting hole on the sheet metal surface. The terminal portion 1.5 is located in the middle of the front part of the base 1.1. The terminal portion 1.5 has multiple terminal cavities 1.6 and through grooves 1.9. The terminal cavities are longitudinal (axial) and the terminal cavities 1.6 pass through the terminal portion 1.5 and the base 1.1. The through grooves 1.9 are transverse and perpendicular to the direction of the terminal cavities 1.6. The sidewalls of the through grooves 1.9 intersect with the sidewalls of the terminal cavities 1.6 and the through grooves 1.9 connect the terminal cavities 1.6. The through grooves are used to insert the crossbar 2.2 of the locking member 2. A cylindrical section 1.2 extends around the front of the base 1.1, surrounding the terminal section 1.5. A locking element 2 is mounted on the cylindrical section 1.2. A through hole 1.8 is formed on the side of the cylindrical section 1.2. A pair of supports 1.7 are provided on the inner side of the cylindrical section 1.2, supporting the locking element. The through hole 1.8 passes through the cylindrical section 1.2 and the supports 1.7, allowing the crossbar 2.2 and cross post 2.3 of the locking element 2 to pass through. A flange 1.4 is provided at the opening of the cylindrical section 1.2, through which a panel-mounted wire harness socket is mounted on the sheet metal surface. A square cover 1.3 extends around the rear of the base 1.1, through which the panel-mounted wire harness socket connects to the plug.

[0017] Two locking elements 2 are fitted onto the cylindrical section 1.2 of the housing 1. The locking elements 2 are arranged symmetrically at 180 degrees around the circumference of the cylindrical section 1.2. Figure 4 and Figure 5 As shown, the lock 2 is integrally formed from a handle 2.1, a crossbar 2.2, and a cross post 2.3. The arc-shaped handle 2.1 connects the crossbar 2.2 and the cross post 2.3. The crossbar 2.2 and the cross post 2.3 are spaced apart and parallel to each other. A protruding strip 2.4 is provided on the side of the crossbar 2.2. The crossbar 2.2 and its protruding strip 2.4 pass through the through hole 1.8 and are inserted into the through groove 1.9. The protruding strip serves a guiding function and increases the strength of the crossbar. A window 2.5 is machined in the middle of the cross post 2.3, and a hook 2.6 extends from the window. The hook 2.6 will bend and deform when blocked by the through hole 1.8 of the bracket 1.7 or when subjected to external pressure.

[0018] like Figure 6 As shown, terminal A is inserted into terminal cavity 1.6 of housing 1, and wire harness B is led out from terminal A. Locking member 2 passes sequentially through cylinder 1.2, bracket 1.7 and terminal part 1.5 of housing 1, with the insertion direction of locking member 2 perpendicular to the insertion direction of terminal A. The crossbar 2.2 of locking member 2 is inserted into through groove 1.9, and the side of crossbar 2.2 is locked at the positioning position of terminal A, thereby restricting the terminal from dislodging and preventing the terminal from detaching from the terminal cavity due to the pulling force of the wire harness or the insertion force of the plug and its terminals, thus realizing the function of locking the terminal.

[0019] After the horizontal post 2.3 of the locking piece 2 passes through the through hole 1.8 of the bracket 1.7, the hook 2.6 latches onto the bracket 1.7, preventing the locking piece 2 from dislodging and thus achieving the function of locking the locking piece. When it is necessary to pull out the terminal, the locking piece 2 must be unlocked first, that is, the hook 2.6 must be pressed down first, causing the hook 2.6 to bend and deform to avoid the through hole 1.7 of the bracket 1.7, and then the locking piece is unlocked. Then, the locking piece is completely pulled out, and the terminal is unlocked.
