Description

Technical Field

[0001] The utility model relates to the field of connector structures, in particular to a locking type connector assembly. Background Art

[0002] An electronic connector is a conductor device that connects electrical circuits. This part can be used as an endpoint for connecting different components in the same circuit system, or provide power and data connections between different circuit systems and devices. It is widely used in various electrical circuits to connect or disconnect circuits. This connection may be temporary and easy to plug and unplug at any time, or it may be a permanent node between electrical equipment or cables.

[0003] For connectors that are plugged in and out at any time, snap connections are often used. The snaps are snapped into the raised parts of the socket or into the slots. When the connector assembly needs to be disassembled, the front end of the pressure plate with the snaps is pressed down, and the snaps at the rear end of the pressure plate are tilted upward, thereby unlocking the snaps and facilitating removal. However, the front end force arm of the fulcrum between the pressure plate and the connector assembly is short. When the front end of the pressure plate is pressed down with the fingers, the fingertips are subjected to a large reaction force, especially when pressed on the edge of the pressure plate, the discomfort is even stronger. Therefore, it is necessary to produce a locking connector assembly to solve the above-mentioned problems. Utility Model Content

[0019] The utility model is further described below in conjunction with the accompanying drawings:

[0020] like Figures 1 to 2As shown, a locking connector assembly includes a connector body 1 and a locking component 2, the locking component 2 includes a connecting rib 21, a pressure plate 22, a pressing rib 23 and a buckle 24, the connecting rib 21 is made of plastic material, the lower end of the connecting rib 21 is fixed to the upper end of the connector body 1, the upper end of the connecting rib 21 is fixed to the lower end surface of the pressure plate 22, the front end of the pressure plate 22 is trapezoidal in shape, and the lower bottom of the trapezoid faces the front side, the pressing rib 23 is fixed to the front side of the upper end of the pressure plate 22, the pressing rib 23 is provided with rounded corners around, and the buckle 24 is fixed to the rear side of the lower end of the pressure plate 22.

[0021] When inserting the connector body 1 into the connector socket, press the front end of the pressure plate 22 with your fingers. The connecting rib 21 is a plastic component with a certain elastic deformation. The buckle 24 at the rear end of the pressure plate 22 is tilted upward around the connecting rib 21. After the connector body 1 is inserted into place, the pressure plate 22 is reset, and the buckle 24 is buckled with the raised part on the connector socket or with the groove.

[0022] By setting the front end of the pressing plate 22 into a trapezoid, the area available for pressing at the front end of the pressing plate 22 is larger, and the fingertips are not easy to press on the edge positions on the left and right sides of the pressing plate 22. The force-bearing area during pressing is also larger, and pressing is more labor-saving. On the other hand, a pressing rib 23 with rounded corners is provided above the pressing plate 22. When pressing, the force application point is on the rib, avoiding sharp corners on the force application part, improving the experience during pressing, and reducing discomfort.

[0023] The connecting ribs 21 are provided in two groups and correspond to the left and right sides of the pressing plate 22 respectively.

[0024] Providing two sets of connecting ribs 21 can prevent the pressing plate 22 from being deflected to one side and easily broken when the pressing plate 22 is pressed. The two sets of connecting ribs 21 balance the force on the pressing plate 22 when pressed, thereby increasing its service life.

[0025] The front end of the connecting rib 21 is an arcuate surface 231, which bends backward, and the rear end of the connecting rib 21 is a vertical plane 232. The connecting rib 21 adopts this shape, which is conducive to the bending of the pressing plate 22 to the front side, reducing the pressure required to be applied when pressing the pressing plate 22, making the pressing more labor-saving.

[0026] The front end surface of the buckle 24 is an inclined plane 241, and the inclined plane 241 is inclined forward from top to bottom. The inclined plane 241 is arranged at the front end of the buckle 24 to increase the firmness of the buckle 24 and the connector socket. When in use, the buckle 24 is not easy to loosen.

[0027] The connector body 1 is provided with a mounting cavity and a partition plate 11, and multiple groups of partition plates 11 are provided, and the multiple groups of partition plates 11 divide the mounting cavity into multiple groups of terminal mounting holes 12. The connecting terminals are installed in the terminal mounting holes 12, and the partition plates 11 can prevent two adjacent groups of connecting terminals from contacting during use and causing a short circuit.

[0028] The connector body 1 has a plurality of mounting slots 13 on the upper rear end, each of which is connected to a set of mounting holes. The mounting slots 13 are used to fix the connecting terminals. After assembly, the stopper on the terminal corresponds to the mounting slots 13.

[0029] The lower side of the rear end of the connector body 1 is provided with a plurality of groups of V-shaped grooves 14, and the V-shaped grooves 14 open downward. By providing the V-shaped grooves 14, the upper and lower sides of the rear end of the connector body 1 have different shapes, and the connector socket is also provided with a convex part matching the V-shaped grooves 14, so as to prevent the connector body 1 from being inserted upside down.

[0030] The front end of the connector body 1 is provided with a limiting rib 15, which corresponds to the bottom of the pressing plate 22. The limiting rib 15 can limit the pressing distance of the front end of the pressing plate 22, so as to avoid the pressing plate 22 being broken due to excessive pressing or the pressing plate 22 being unable to return to its original position, resulting in functional failure.

[0031] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
