Description

Technical Field

[0001] This utility model belongs to the field of connector technology, specifically a small-pitch double-row multi-hole wire-to-board connector device. Background Technology

[0002] Connectors, also called plugs or sockets, are generally electrical connectors. They are devices that connect two active devices to transmit current or signals. The male and female terminals, when in contact, can transmit information or current; this is called a connector.

[0003] In the current connector structure, the terminal opening faces outward. When matched with the pin socket, the pin may press against the end face of the spring of the terminal opening, causing the spring to deform and making it difficult to insert. At the same time, the existing terminal and locking plate adopt a single locking structure with a riveting foot, which has poor fixing effect and is prone to terminal displacement. Utility Model Content

[0004] The purpose of this invention is to provide a small-pitch double-row multi-hole wire-to-board connector device to solve the problems mentioned in the background art.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A small-pitch double-row multi-hole wire-to-board connector device includes a male end and a board end, wherein the male end is inserted into the board end;

[0007] The male terminal includes several female terminals, which are arranged in a rectangular array and fixed by locking tabs.

[0008] Preferably, the male terminal body has several grid surfaces on its top, the lower outer side of the grid surfaces has hanging teeth, the lower outer side of the female terminal has a hanging platform, the lower inner side of the female terminal has a female terminal stop block, the female terminal stop block is engaged in the grid groove, and is fixed by the male terminal hanging platform and the hanging teeth.

[0009] Preferably, the top of the locking plate is provided with a male end locking plate anti-reverse support strip, both sides of the locking plate are provided with locking plate hooks, and both sides of the male end body are provided with second buckles, and the locking plate hooks are engaged and connected with their corresponding second buckles.

[0010] Preferably, the top of the plate end body is provided with a plurality of correspondingly arranged long pin positioning slots and short pin positioning slots. The inner sides of the long pin positioning slots and short pin positioning slots are respectively provided with long pin through slots and short pin through slots. The vertical sections of the long pins and short pins are respectively provided with long pin barbs and short pin barbs. The horizontal ends of the long pins and short pins are respectively provided with long pin positioning blocks and short pin positioning blocks. The long pin positioning blocks and short pin positioning blocks are respectively inserted into the long pin positioning slots and short pin positioning slots. The long pin through slots and short pin through slots are respectively engaged with the long pin barbs and short pin barbs and fixed by the stop block surface.

[0011] Preferably, the bottom of the plate end body is provided with a welding sheet fixing groove, and a limiting surface is provided next to the welding sheet fixing groove. The welding sheet is stuck in the welding sheet fixing groove and is fixed by the limiting surface and the welding sheet barbs.

[0012] Preferably, the male end body is provided with guide ribs inside, and the male end is inserted into the plate end, with both the long pin vertical section and the short pin vertical section being inserted into the female end terminal through the guide ribs.

[0013] Preferably, the male end body has anti-foolproof ribs on its side and anti-foolproof grooves inside the plate end body; the male end body has elastic external hooks on its side, the bottom of the elastic external hooks has bottom support rounded corners, and the plate end body has locks inside, with the elastic external hooks and locks cooperating and connected.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0015] In this utility model, the female terminal is forcefully inserted into the male body, and the hook of the male body and the female terminal are invertedly engaged to form a primary anti-detachment mechanism for the terminal. At this time, the male locking piece is inserted into the male body, and the hook of the male locking piece is engaged with the buckle of the male body to form a fixation. The anti-retraction support strip of the male locking piece and the stop block of the female terminal cooperate with each other to form a secondary anti-detachment mechanism for the terminal, and the locking piece will restrict the movement gap of the terminal.

[0016] In this invention, the elastic outer hook of the male end body and the locking buckle of the plate end body are engaged with each other. Due to the pulling and rebounding effect of the bottom support rounded corner of the elastic outer hook during the insertion process, the overall strength of the elastic outer hook is enhanced, which can effectively improve the problem of the elastic outer hook not rebounding during the use of the connector.

[0017] In this invention, the bubble point adopts an arc-shaped structure, with its arc surface tangent to the vertical section of the pin. It is inserted through a guide rib, which avoids the risk of the pin hitting the terminal flared mouth, protects the pin, facilitates insertion and removal, and the pin only needs to be stamped and formed in one go, and then directly assembled. The process is simple and effectively ensures the stability of product quality. Attached Figure Description
