Description

Technical Field

[0001] This utility model relates to the field of electrical connection technology, and in particular to a connector with a robust structure and convenient assembly. Background Technology

[0002] Connectors are widely used in electronic devices to achieve electrical connections between circuits. Existing connectors, especially those for connecting cable trays, typically consist of a body and a top cover. However, traditional methods of fixing the top cover to the body often result in complex structures, inconvenient assembly, or insufficiently secure connections. In applications with frequent vibration or insertion / removal, the top cover is prone to loosening, leading to poor terminal contact and affecting the reliability of signal transmission. Therefore, there is an urgent need for an improved connector structure to address these issues. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a connector that achieves a stable connection between the top cover and the connector body through a multi-point, multi-directional snap-fit ​​structure, while ensuring ease of assembly.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A connector includes a connector body, a top cover, terminals, and a locking mechanism. The connector body has a insertion slot for cable routing, and at least one connection slot is formed on the side wall of the insertion slot. The top cover covers the connector body, and the terminals are inserted into the connection slots.

[0006] The engaging mechanism is used to achieve a fixed connection between the upper cover and the connector body, and includes:

[0007] The connector body has locking blocks on both sides and grooves on both sides of the top cover that engage with the locking blocks.

[0008] A snap-fit ​​groove is provided on the end face of the connector body, and a fixing part is provided on the upper cover and snaps into the snap-fit ​​groove.

[0009] As a further improvement of this utility model, the engaging mechanism further includes an elastic connecting arm disposed on the upper cover and an elastic connecting groove disposed on the end face of the connector body, wherein the elastic connecting arm is connected to the elastic connecting groove.

[0010] As a further improvement of this utility model, the elastic connecting arm is integrally formed with the upper cover.

[0011] As a further improvement of this utility model, the upper cover is also provided with an integrally formed welding part for welding and fixing to an external circuit board.

[0012] As a further improvement of this utility model, the insertion slot, connection slot, locking block, locking groove and elastic connection slot on the connector body are integrally injection molded.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] This invention's connector utilizes a multi-point locking mechanism comprised of a locking block and groove, a fixing part and a locking slot, to achieve a secure lock between the top cover and the connector body in multiple lateral and end directions, effectively preventing the top cover from loosening. In the preferred embodiment, the addition of an elastic connecting arm and an elastic connecting groove further enhances the structural integrity of the other end of the connector. This structure not only provides a reliable connection and can withstand certain vibrations and impacts, but also simplifies and speeds up assembly, requiring no additional fasteners, thus improving production efficiency and reducing costs.

[0020] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0021] Implementation, for example Figures 1 to 4 As shown, the connector provided by this utility model has a flat cuboid structure as its main body, and mainly includes a connector body 1, an upper cover 2, and terminals 3.

[0022] The connector body 1 is integrally injection molded from insulating material, and has a main insertion slot (not individually labeled) for accommodating the cable strip (not shown in the figure). Multiple connecting slots (not individually labeled) are formed on the side wall of the insertion slot for connecting terminals 3. Three retaining blocks 6 are provided on each of the two side walls of the connector body 1. A retaining groove 8 is formed on the end face of the connector body 1 near the cable strip insertion port. An elastic connecting groove 10 is formed on the end face away from the cable strip insertion port.

[0023] The top cover 2 is also made of insulating material, and its shape matches that of the connector body 1. Grooves 9, corresponding to the positions and number of locking blocks 6 on the connector body 1, are formed on both side walls of the top cover 2. A downwardly protruding fixing part 7 is provided at one end of the top cover 2. An elastic connecting arm 4, integrally formed with the top cover 2, is provided at the other end of the top cover 2. Furthermore, an integrally formed soldering part 5, which can be in the form of a pin or a pad, is provided on the top of the top cover 2 for soldering and fixing the entire connector to the PCB board. During assembly, the terminals 3 are first inserted into the connecting slots of the connector body 1. Then, the top cover 2 is aligned with the connector body 1 and closed. During this process, the grooves 9 on both sides of the top cover 2 engage with the locking blocks 6 on both sides of the connector body 1, achieving lateral fixation. Simultaneously, the fixing part 7 at the front end of the top cover 2 engages with the locking groove 8 at the front end of the connector body 1, achieving end-position fixation. The elastic connecting arm 4 at the rear end of the top cover 2 will undergo elastic deformation and then engage or connect to the elastic connecting groove 10 at the rear end of the connector body 1, thereby achieving auxiliary fixation and connection at the other end. Through this multi-point engagement method combining lateral and end engagement, the top cover 2 and the connector body 1 are firmly fixed together, forming a structurally stable and highly reliable whole.
