Description

Technical Field

[0001] The utility model relates to an electrical connector and a connector assembly, belonging to the technical field of connectors. Background Art

[0002] The connector assembly in the related art usually includes a plug connector and a socket connector that cooperate with each other. The socket connector includes a socket insulating body, a plurality of socket conductive terminals fixed in the socket insulating body, and a metal housing covering the periphery of the socket insulating body. The metal housing is provided with a first locking hole and a second locking hole.

[0003] The plug connector usually includes a plug insulating body, a tongue plate, a locking spring piece, and a pulling belt. A plurality of conductive sheets are provided on the tongue plate, and the conductive sheets are in contact with the socket conductive terminals. The locking spring piece usually includes a first locking protrusion, a second locking protrusion, and a connecting rod. The first locking protrusion and the second locking protrusion are used to cooperate with the first locking hole and the second locking hole. The connecting rod is connected to the pulling belt to apply an external force. The external force can drive the first locking protrusion and the second locking protrusion to move, so as to achieve unlocking.

[0004] However, the connecting rod in the related art is similar to a cross beam and is connected between the first locking protrusion and the second locking protrusion. When an external force acts on the connecting rod through the pulling belt, since the length of the connecting rod is usually long, it is prone to elastic deformation itself. Those skilled in the art can understand that whether unlocking can be successful depends on whether the first locking protrusion and the second locking protrusion can be driven by the connecting rod to disengage from the first locking hole and the second locking hole. With the development trend of miniaturization of connectors, the space left on the plug connector for the locking spring piece to deform to achieve unlocking has become smaller and smaller, and the elastic deformation of the connecting rod itself will offset a part of the unlocking space, so it is easy to cause unlocking failure.

[0005] Therefore, it is necessary to improve the connector assembly in the related art. Summary of the Utility Model

[0088] Please refer to Figures 20 to 22 As shown, in another embodiment of the present utility model, the connecting wall 33 and the reinforcing wall 35 are two parts, and the reinforcing wall 35 is in contact with and fixed to the connecting wall 33. In another embodiment of the present utility model, the connecting wall 33 is U-shaped, and the reinforcing wall 35 is also U-shaped. The shape and size of the reinforcing wall 35 are adapted to the shape and size of the connecting wall 33, and the outer side surface of the reinforcing wall 35 is closely attached to the inner side surface of the connecting wall 33. In the illustrated embodiment of the present utility model, the force on the latch spring piece 3 is applied by pulling the pull strap 30 with an external force. Of course, in other embodiments, the external force can also be directly applied to the latch spring piece 3, which will not be elaborated in the present utility model.

[0089] When the electrical connector 100 is docked with the docking connector 200, the first locking protrusion 3121 and the second locking protrusion 3221 of the electrical connector 100 are respectively locked in the first locking hole 911 and the second locking hole 912 of the docking connector 200 to prevent the electrical connector 100 and the docking connector 200 from loosening or detaching due to improper external force.

[0090] When unlocking is required, an external force acts on the drawstring 30 (for example, pulling the drawstring 30 backward). The utility model increases the structural strength of the connecting wall 33 by providing the reinforcing wall 35, so that when the drawstring 30 is pulled by an external force, the connecting wall 33 fastened with the drawstring 30 has good rigidity and is not easy to elastically deform. At this time, the external force is more likely to drive the first locking piece 312 and the second locking piece 322 to elastically deform through the connecting wall 33, so that the first locking protrusion 3121 and the second locking protrusion 3221 are separated from the first locking hole 911 and the second locking hole 912 of the docking connector 200, thereby achieving unlocking.

[0091] Since the connecting wall 33 is connected between the first locking portion 31 and the second locking portion 32, the connecting wall 33 is a type of a lever arm cantilever beam, which is easy to produce elastic deformation when subjected to force, so that the external force cannot be well transmitted to the first locking piece 312 and the second locking piece 322, thereby affecting the deformation of the first locking protrusion 3121 and the second locking protrusion 3221. In the embodiment of the utility model shown in the figure, by providing the reinforcing wall 35, the structural strength of the connecting wall 33 is increased, the risk of elastic deformation of the connecting wall 33 is reduced, and the reliability of the connecting wall 33 driving the first locking portion 31 and the second locking portion 32 to produce elastic deformation is improved, thereby improving the reliability of unlocking.

[0092] The above implementation modes are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. The understanding of the present invention should be based on the technical personnel in the relevant technical field. Although the present invention has been described in detail in this specification with reference to the above implementation modes, ordinary technical personnel in the field should understand that the technical personnel in the relevant technical field can still modify or make equivalent substitutions to the present invention, and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
