Description

Technical Field

[0001] The present application relates to the technical field of conductive elements, and in particular to a connector. Background Art

[0002] Connectors are used to connect two active devices to transmit current or signals.

[0003] In the related art, the connector includes a housing and a connection terminal, and a spring is arranged on the connection terminal. A mounting groove is provided on one side of the housing, and a socket for inserting the spring is provided on the inner wall of the mounting groove.

[0004] The spring clip on the terminal is inserted into the socket, making it difficult for the terminal to be pulled out of the mounting slot. However, due to the small size of the terminal and the spring clip, the stability of the terminal when connected to the housing is poor. When the staff pulls the terminal, it is easy to separate the terminal from the housing, so there is room for improvement. Utility Model Content

[0005] In order to improve the stability when the terminal is connected to the housing, the present application provides a connector.

[0006] The present application provides a connector, which adopts the following technical solution:

[0007] A connector comprises a shell, wherein an end surface of the shell is provided with a mounting groove, a wiring terminal is installed in the mounting groove, and an inner wall of the mounting groove is provided with a locking structure for locking the wiring terminal; an operating hole is provided on the inner wall of the mounting groove, an operating plate is rotatably connected in the operating hole, an operating block is provided on the side of the operating plate away from the insertion direction of the wiring terminal, a socket is provided on the wiring terminal for the operating plate and the operating block to be rotated into, and a locking piece for limiting the rotation of the operating block is provided on the shell.

[0008] By adopting the above technical solution, the wiring terminal is inserted into the installation groove, the socket is aligned with the operation hole, and then the operation block is driven to rotate so that the operation panel and the operation block are both transferred into the socket, so that the operation block is located on the moving path of the wiring terminal, so that the wiring terminal is not easily separated from the shell; when the connector is used with the matching connector, the plug-in terminal in the matching connector can be inserted into the wiring terminal, and the setting of the operation panel plays a limiting role on the plug-in terminal to prevent the plug-in terminal from being inserted too deeply.

[0009] Optionally, a cylinder is provided on one side of the operating panel along the width direction of the shell, the axis of the cylinder is perpendicular to the insertion direction of the terminal block, and the locking piece includes a card block provided on the inner wall of the operating hole along the axis of the cylinder, and the operating block is provided with a second card slot for the card block to be embedded in the end face of the cylinder.

[0010] By adopting the above technical solution, when the card block is embedded in the second card slot, the operating block is locked so that it is difficult to rotate. At this time, the operating block is on the moving path of the wiring terminal, so that the wiring terminal is not easily separated from the housing.

[0011] Optionally, a limiting groove is provided on the inner wall of the operating hole away from the opening of the installation groove, and the limiting groove penetrates the shell in a direction away from the installation groove, and a limiting block inserted into the limiting groove is provided on the operating block.

[0012] By adopting the above technical solution, when the limiting block contacts the inner wall of the limiting groove close to the installation groove, the rotating operation block continues to rotate to play a limiting role.

[0013] Optionally, the end surface of the operating plate facing the cylinder is provided with a first card slot for the card block to be embedded in.

[0014] By adopting the above technical solution, when the card block is embedded in the first card slot, the operating panel is locked so that the operating panel is not easy to rotate. At this time, the operating panel and the operating block are not in the moving path of the wiring terminal, which facilitates the installation of the wiring terminal into the shell or the separation of the wiring terminal from the shell.

[0015] Optionally, a reinforcement block is provided on one side of the operating panel facing the operating block, and one end of the reinforcement block is connected to the operating block.

[0016] By adopting the above technical solution and arranging the reinforcing block, the strength between the operating panel and the operating block is improved, and the operating panel and the operating block are not easily damaged when the operating panel rotates.

[0017] Optionally, a guide groove is provided on the inner wall of the installation groove along the cylindrical axis direction, and the guide groove penetrates the shell in the direction of the installation groove opening. A guide piece is provided on the side of the terminal block, and the guide piece is slidably arranged in the guide groove.

[0018] By adopting the above technical solution, the guide piece is slidably arranged in the guide groove, which has a guiding effect on the installation of the terminal. In addition, the guide piece is placed in the guide groove, so that the terminal is not easy to move along the width and thickness directions of the shell, which plays a limiting role.

[0019] Optionally, a spring sheet is provided on a side of the wiring terminal away from the operating hole, and an insertion hole for inserting the spring sheet is provided on an inner wall of the mounting slot away from the operating hole, and a distance between the spring sheet and the wiring terminal gradually increases in a direction approaching the mounting slot opening.

[0020] By adopting the above technical solution, when the terminal is installed in the shell, the spring sheet contacts the shell and is compressed and deformed. When the spring sheet is aligned with the socket, the spring sheet is inserted into the socket when it is reset. When the terminal is moved in a direction away from the bottom wall of the installation groove, the spring sheet contacts the inner wall of the socket away from the bottom wall of the installation groove, thereby preventing the terminal from detaching from the installation groove and further improving the stability of the connection between the terminal and the shell.

[0021] Optionally, a sliding groove is provided on the inner wall of the installation groove away from the operating hole, the sliding groove is located on the side of the socket away from the bottom wall of the installation groove, one end of the sliding groove is connected to the socket, and the end of the sliding groove away from the socket passes through the shell.

[0022] By adopting the above technical solution, the slide groove has a guiding effect on the spring piece, which facilitates the spring piece to move toward the socket; the cooperation between the slide groove and the spring piece, and the cooperation between the guide piece and the guide groove realizes a single installation method of the terminal block, which plays an anti-mistake effect.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Insert the terminal block into the installation slot, align the socket with the operating hole, and then drive the operating block to rotate so that the operating panel and the operating block are both transferred into the socket, so that the operating block is on the moving path of the terminal block, so that the terminal block is not easily separated from the housing; when the connector is used with the matching connector, the plug-in terminal in the matching connector can be inserted into the terminal block, and the setting of the operating panel plays a limiting role on the plug-in terminal to prevent the plug-in terminal from being inserted too deep;

[0025] 2. Guide blocks and guide grooves are provided to guide the installation of the terminal blocks, making it easier to align the sockets with the operating holes. BRIEF DESCRIPTION OF THE DRAWINGS
