Description

Technical Field

[0001] The utility model relates to a plastic high-voltage connector, in particular to a novel double-locking plastic high-voltage connector. Background Art

[0002] Most traditional high-voltage plastic connectors use a single-stage unlocking mechanism. Unlocking due to accidental contact or other external environmental factors can significantly reduce the safety of high-voltage connectors by failing to provide a double-safety mechanism. Existing dual-unlocking connectors on the market are complex and costly. Utility Model Content

[0003] In response to the problems existing in the prior art, the utility model provides a new type of double-locking plastic high-voltage connector. The double-locking design of this structure is simple in structure, single in parts, low in cost, and effectively solves the problems of complex and high-cost double-lock structures on the market, and also solves the insecurity problem of single-stage unlocking.

[0004] The technical solution of the utility model is: a novel double-locking plastic high-voltage connector, comprising a connector plug and a connector socket, wherein the connector plug comprises a plug housing, and the connector socket comprises a socket housing;

[0005] A socket protrusion and a socket buckle groove are provided on one side of the outer surface of the socket shell, one in front of the other in the axial direction, wherein the socket protrusion is located at an end of the outer surface of the socket shell close to one end of the plug shell, and the socket buckle groove is located behind the socket protrusion, and the radial height of the socket protrusion is lower than the radial height of the socket buckle groove;

[0006] A first plug buckle plate and a second plug buckle plate are provided on one side of the outer surface of the plug housing in a radial direction, one above the other. The first plug buckle plate is located above the second plug buckle plate. The buckle of the first plug buckle plate can buckle the socket buckle groove when the connector plug and the connector socket are plugged in. The buckle of the second plug buckle plate can buckle the socket protrusion when the connector plug and the connector socket are plugged in.

[0007] The pressing portion of the first plug buckle plate is located directly above the buckle of the second plug buckle plate, and the pressing portion of the second plug buckle plate is exposed to the rear side of the pressing portion of the first plug buckle plate, so that the pressing portion of the first plug buckle plate and the pressing portion of the second plug buckle plate can be pressed at the same time.

[0008] Furthermore, the outer surface of the first plug plate is provided with anti-slip protrusions.

[0009] The beneficial effects of the utility model are:

[0010] 1. Double locking solves the insecurity of single-level locking and will not be unlocked due to failure of one part.

[0011] 2. The double locking principle of this structure is simple, and the production and assembly are simpler.

[0012] 3. Press two positions at the same time to unlock, which increases the difficulty of unlocking but improves product safety.

[0013] 4. Double gussets are made of one part, reducing product costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] like Figure 1-4 As shown, a novel double-locking plastic high-voltage connector includes a connector plug and a connector socket, wherein the connector plug includes a plug housing 2 and the connector socket includes a socket housing 1 .

[0021] A socket protrusion 4 and a socket buckle groove 3 are provided on one side of the outer surface of the socket shell 1, one in front and one behind in the axial direction. The socket protrusion 4 is located at the end of the outer surface of the socket shell 1 close to one end of the plug shell 2, and the socket buckle groove 3 is located on the rear side of the socket protrusion 4. The radial height of the socket protrusion 4 is lower than the radial height of the socket buckle groove 3.

[0022] A first plug plate 5 and a second plug plate 6 are radially disposed one above the other on one side of the outer surface of the plug housing 2. The outer surface of the first plug plate 5 is provided with anti-slip protrusions. The first plug plate 5 is located above the second plug plate 6. The latch of the first plug plate 5 can engage the socket latch groove 3 when the connector plug and the connector socket are plugged together. The latch of the second plug plate 6 can engage the socket protrusion 4 when the connector plug and the connector socket are plugged together.

[0023] The pressing portion of the first plug buckle plate 5 is located directly above the buckle of the second plug buckle plate 6, and the pressing portion of the second plug buckle plate 6 is exposed to the rear side of the pressing portion of the first plug buckle plate 5, so that the pressing portion of the first plug buckle plate 5 and the pressing portion of the second plug buckle plate 6 can be pressed at the same time.

[0024] Lock: As Figure 1 and Figure 1 As shown: the plug and socket are aligned according to the anti-foolproof key position and then plugged together. At this time, the first plug buckle plate 5 on the plug shell 2 is buckled into the socket buckle groove 3 of the socket shell 1, and the second plug buckle plate 6 of the plug shell 2 is buckled into the socket protrusion 4 of the socket shell 1, thereby achieving double locking.

[0025] Unlock: As Figure 2 As shown: First, you need to press the first plug buckle plate 5 and the second plug buckle plate 6 of the plug shell 2 at the same time. At this time, the first plug buckle plate 5 and the socket buckle groove 3 of the socket shell 1 are separated, and the second plug buckle plate 6 and the socket protrusion 4 are separated, thereby achieving double separation.

[0026] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
