Description

Technical Field

[0001] This utility model relates to the technical field of connectors, and in particular to a through-wall plug-in connector. Background Technology

[0002] Connectors typically consist of a plug, a socket, and a housing. The plug is installed inside the housing and inserts into the socket. To ensure the plug and socket remain connected, a locking connector is usually installed on the inner wall of the housing, and a flexible locking plate is installed on the socket. After the plug and socket are inserted, the locking connector engages with the locking hole on the locking plate to prevent disconnection. To unlock, a screwdriver is inserted into the notch on the top of the locking plate and pushed down to separate the locking hole from the locking connector. Then, pulling either the housing or the socket will separate them. When two identical connectors are installed one above the other and close together, the lower connector cannot be unlocked with a screwdriver, limiting its installation and use. Furthermore, the plug and housing are usually fixed together with screws, resulting in slow assembly speed and impacting production efficiency. Utility Model Content

[0003] In order to overcome the existing technical defects, the purpose of this utility model is to provide a through-wall plug-in connector to solve the above-mentioned technical problems.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0005] According to one aspect of this utility model, a through-wall plug-in connector is designed, comprising: a plug, a socket, a housing, and an unlocking component. The plug is snapped into the housing, and a snap-fit ​​connector is provided in the upper part of the housing. The socket has a snap-fit ​​plate with an elastic structure on its upper part, and a snap-fit ​​position is provided on the snap-fit ​​plate. The unlocking component is placed on the housing and has an unlocking part with an elastic structure. The bottom of the unlocking part has a protrusion that inserts into a notch on the housing. When the plug is plugged into the socket, the snap-fit ​​connector engages with the snap-fit ​​position. At this time, the protrusion is located above one end of the snap-fit ​​plate. When the unlocking part is pressed down, the protrusion moves down against one end of the snap-fit ​​plate, causing the snap-fit ​​position to disengage from the snap-fit ​​connector.

[0006] Using the above technical solution, when the two connectors are installed one above the other and the distance between them is relatively short, the plug and socket of the lower connector need to be separated. This is achieved by pressing down on the unlocking part with a finger or by using a screwdriver or other components to push down on the unlocking part. The unlocking part causes the protrusion to press down on one end of the snap-fit ​​plate, disengaging the snap-fit ​​position from the snap-fit ​​connector. Then, pulling the outer shell separates the plug and socket. This solves the technical problem of the lower connector's plug and socket being unable to connect when the two connectors are installed close together, thus expanding the connector's installation and application scenarios. Furthermore, the snap-fit ​​connection between the plug and the outer shell, compared to the existing screw-based connection, increases installation speed and improves connector production efficiency.

[0007] To better address the aforementioned technical deficiencies, this utility model also offers a superior technical solution:

[0008] In some embodiments, the socket is provided with a resilient retaining plate on at least one side, the resilient retaining plate is provided with a retaining head, and the housing is provided with a retaining groove that engages with the retaining head.

[0009] In some embodiments, the elastic plate has an inclined surface. When it is necessary to remove the plug from the housing, a flathead screwdriver is used to press against the inclined surface to move one end of the elastic plate toward the inside of the plug, causing the clip to disengage from the slot. Then, pulling the plug can remove it from the housing, facilitating plug maintenance.

[0010] In some embodiments, a guide groove is provided at the bottom of the plug, and a guide block is provided inside the housing to slide in conjunction with the guide groove. The cooperation between the guide groove and the guide block can, on the one hand, achieve guided installation, and on the other hand, prevent the upper and lower parts of the plug from being installed inside the housing in an inverted state, thus achieving a foolproof installation effect.

[0011] In some embodiments, the unlocking element has an inverted U-shaped structure, the inner side profile of which matches the rear end profile of the housing and slides longitudinally with the housing.

[0012] In some embodiments, limit strips are provided on the left and right sides of the outer casing, and limit blocks located below the limit strips are provided on the inner sidewalls of the left and right ends of the unlocking member.

[0013] In some embodiments, the limiting strip is provided with a groove for the limiting block to pass through. When the unlocking part is moved upward to separate the protrusion from the notch, and the unlocking member is moved to align the limiting block with the groove, the upward-moving unlocking member can remove it, preventing others from separating the plug from the socket through the unlocking member.

[0014] In some embodiments, the plug is provided with a six-lobed beryllium copper crown spring, and the socket is provided with conductive pins to which the beryllium copper crown spring is inserted.

[0015] In some embodiments, a sealing ring is provided in the annular groove of the socket, and when the plug is inserted into the socket, the sealing ring makes sealing contact with the inner wall of the housing. Attached Figure Description
