Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically a novel connector cover. Background Technology

[0002] Connectors are widely used in various electronic devices to connect two independent circuits and transmit information or current. The connector cover, as an important component of the connector, serves to protect the internal terminal components and improve connection stability. However, existing connector covers often use simple two-point snap-fit ​​or threaded fastening methods, which result in unstable fixation, especially in connectors with multiple rows of terminals.

[0003] These types of connectors are prone to problems such as broken contacts and detachment during use, leading to poor circuit connections and affecting the normal operation of equipment. These problems mainly stem from the limitations of existing connectors and connector cover fixing structures. They struggle to effectively overcome the difficulties in fixing multiple rows of terminals with large contact areas and complex structures, resulting in insufficient connector reliability.

[0004] Therefore, it is necessary to provide a new type of connector cover that can effectively improve the fixing stability of the connector, enhance the connection reliability, and improve the practicality and safety of the connector. Utility Model Content

[0005] This utility model proposes a novel connector cover to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

The upper part of the plastic housing is a snap-fit ​​part, and several locking positions are provided on both sides of the snap-fit ​​part. Positioning blocks are provided at both ends of the snap-fit ​​part. A snap-fit ​​groove is provided at the bottom of the plastic cover. The snap-fit ​​part is inserted into the snap-fit ​​groove, and several locking points are provided on both sides of the snap-fit ​​groove. The locking points are engaged with the locking positions. Positioning grooves are provided at both ends of the plastic cover, and the positioning blocks are slidably inserted into the positioning grooves.

[0008] Preferably, the top surface of the plastic cover is provided with a through groove, the lower part of the plastic shell is a connecting part, the top surface of the fastening part is provided with a plurality of terminal receiving cavities, the bottom surface of the connecting part is provided with a plurality of insertion holes, and the insertion holes are connected to the terminal receiving cavities one by one. The top surface inside the fastening groove is provided with a plurality of terminal insertion positions, and the terminal insertion positions are connected to the terminal receiving cavities.

[0009] Preferably, the positioning block has chamfered edges at both the top and bottom of its outward-facing side. The positioning block is used to improve the accuracy of the mating of the plastic shell and the plastic cover, thereby improving processing efficiency and assembly precision.

[0010] Preferably, the plastic cap has pressing handles at both ends, the lower end of the pressing handles is connected to the plastic cap, and the positioning groove is formed by a V-shaped structure between the pressing handles and the plastic cap. The end of the pressing handle connected to the plastic cap extends downward to form a buckle. The buckle is used to connect with an external male connector.

[0011] Preferably, the locking slot is a square through hole, and the locking slot has two rows arranged vertically. The locking point is a trapezoidal protrusion with an inclined surface on its side, and the locking point has two rows that correspond one-to-one with the locking slot. The inclined surface, combined with the elastic properties of the plastic, facilitates the locking point to engage with the locking slot.

[0012] Preferably, both the sockets and the terminal receiving cavities are provided in two rows. Different numbers of sockets and terminal receiving cavities in the plastic housing can be selected for use according to different circuit requirements.

[0013] Preferably, each of the terminal receiving cavities is provided with a metal terminal, the two ends of which are a spring clip and a welding pin, wherein the welding pin is located in the terminal insertion position and the spring clip is located in the insertion hole.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention achieves a multi-point locking method by setting multiple corresponding locking positions and points on both sides of the plastic shell and both sides of the plastic cover, thereby improving the stability of the plastic shell and plastic cover, effectively protecting the metal terminals, and effectively solving the problem of unstable fixing of existing connector covers, especially in connectors with multiple rows of terminals. When connected with the external male connector in conjunction with the snap-fit, a three-layer protective fixing structure of plastic cover-plastic shell-male connector is formed, further improving the safety of the metal terminals, enhancing connection stability, and ensuring a more secure connection between the male connector, plastic cover, and plastic shell, preventing problems such as detachment or broken contact, thus improving the practicality and safety of the connector.
