Technical Field

[0001] This application relates to the technical field of electronic connectors, and more particularly to a connector. Background Technology

[0002] In various electronic systems, electrical connectors are essential basic components for making a complete system, enabling electrical connections and signal transmission between devices, components, and systems.

[0003] Currently, Chinese patent CN219268000U discloses a D-sub connector structure, including an insulating body with terminal groups, a metal shell fixed to the front end of the insulating body, harpoon plate locks located on both sides of the rear of the insulating body, and two fixing nuts located on both sides of the connector and extending forward and backward; the metal shell and / or harpoon plate locks have 4-6 lateral positioning holes for the fixing nuts to pass through; the fixing nuts have a sleeve section with internal threads located at the front end of the metal shell, a positioning section whose cross-section is adapted to the positioning hole, and a riveting end for riveting and fixing to the rear surface of the harpoon plate lock.

[0004] Because the connection of the harpoon plate lock relies on the riveting end of the fixing nut, and the riveting of the fixing nut requires special riveting equipment, when riveting the fixing nut, the operator needs to first let the fixing nut pass through the connector and the harpoon plate lock before using special equipment to rivet it, which makes the product assembly more complicated. Utility Model Content

[0005] To facilitate product assembly, this application provides a connector.

[0006] The connector provided in this application adopts the following technical solution: A connector includes a body, a harpoon, and a metal housing, and further includes a connecting assembly disposed on the metal housing and connected to the body, wherein a portion of the harpoon is located on the side of the body close to the metal housing and is defined on the body by the metal housing.

[0007] By adopting the above technical solution, the harpoon is first made to contact the main body, and then the metal shell is connected to the main body through the connecting component. When the metal shell is installed on the main body, the harpoon will be limited to the main body by the metal shell, thus reducing the riveting operation with riveting equipment; therefore, the connector provided in this application facilitates the assembly of the product.

[0008] Optionally, the harpoon includes a first connecting block, a second connecting block, a third connecting block, and a claw. The first connecting block is located on the side of the main body close to the metal shell, and the metal shell abuts against the first connecting block. The second connecting block is disposed on the first connecting block, and the claw is disposed on the second connecting block. The main body has a first through hole, the third connecting block is disposed on the first connecting block and located in the first through hole, the third connecting block has a first threaded hole, and the metal shell has a second through hole communicating with the first threaded hole.

[0009] By adopting the above technical solution, when the first connecting block is connected to the main body through the metal shell, the first threaded hole on the third connecting block can realize the reliable connection between the connector and the external plug-in through screw locking.

[0010] Optionally, the main body has a limiting groove communicating with the first through hole, the first connecting block is located in the limiting groove, and the metal shell abuts against the main body and the first connecting block.

[0011] By adopting the above technical solution, when the first connecting block is located in the limiting groove, the side wall of the first connecting block away from the claw is in the same plane as the side wall of the plastic body with the limiting groove; the limiting groove not only positions the harpoon, but also allows the metal shell to abut against the main body during subsequent metal shell installation.

[0012] Optionally, the main body is provided with a fixing groove, the second connecting block is provided with a third through hole, the connecting component includes a latch, and multiple latches are provided. One end of the latch is connected to the metal shell, a portion of the latches are directly pressed against the side wall of the fixing groove at the end away from the metal shell, and the remaining latches are pressed against the side wall of the fixing groove at the end away from the metal shell through the third through hole.

[0013] By adopting the above technical solution, when the end of the latch away from the metal shell is located in the fixing groove and abuts against the side wall of the fixing groove, the metal shell will abut against the first connecting block located on the main body; a portion of the latches away from the metal shell will pass through the third through hole on the second connecting block before being located in the fixing groove, which can limit the harpoon with the latches, and realize the metal shell, harpoon and main body are firmly connected together to reduce the phenomenon of separation.

[0014] Optionally, the main body has a receiving hole and a tunnel groove communicating with the receiving hole, a portion of the second connecting block is located in the tunnel groove, and the remaining second connecting block is located in the receiving hole.

[0015] By adopting the above technical solution, a portion of the second connecting block is located in the tunnel groove, which can position the second connecting block and realize the rapid installation of the harpoon; it can also limit the second connecting block and reduce the phenomenon of the second connecting block shaking during subsequent use of the harpoon; therefore, the tunnel not only facilitates the installation of the harpoon, but also improves the stability of the harpoon on the main body.

[0016] Optionally, the metal housing has a fourth through hole, the main body has a second threaded hole, and the connecting assembly includes a connecting bolt, which passes through the fourth through hole and is threadedly connected to the second threaded hole.

[0017] By adopting the above technical solution, the connecting bolt passes through the fourth through hole on the metal shell and is threadedly connected to the second threaded hole on the main body, thereby connecting the metal shell to the main body.

[0018] Optionally, the main body is provided with a stabilizing mechanism, which includes a stabilizing block and an adjusting component. The stabilizing block is slidably disposed on the main body through the adjusting component, and the stabilizing block abuts against the first connecting block located in the limiting groove.

[0019] By adopting the above technical solution, when the first connecting block is located in the limiting groove, the adjusting component drives the stabilizing block to move, so that the stabilizing block presses against the first connecting block located in the limiting groove. In this way, when the metal shell is installed on the main body later, the phenomenon of the first connecting block moving out of the limiting groove is reduced, thereby improving the stability of the first connecting block in the limiting groove and facilitating the installation of the metal shell.

[0020] Optionally, the main body includes a plastic body, a signal terminal, and a rear cover. The signal terminal is disposed on the plastic body, and the rear cover is disposed on the plastic body. The rear cover has a fifth through hole for the signal terminal to pass through. The metal housing is disposed on the plastic body through the connecting assembly, and the harpoon abuts against the plastic body.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. The connector provided in this application facilitates product assembly; 2. The tunnel not only facilitates the installation of the harpoon, but also improves the stability of the harpoon on the main body. Attached Figure Description
