Description

Multi-section flip cover and flip cover type connector

Technical Field

The present utility model relates to the field of electrical connectors, and more particularly, to a multi-section flip and flip-type connector.

Background

When the flip cover connector is in a completely opened state and is subjected to installation operation, the flip cover cannot be kept stable in the opened state, and can be closed or tend to be closed due to the influence of factors such as product overturning and vibration, so that great trouble is brought to product assembly; when the flip cover of the connector is completely closed but is not finally fastened by the screw, the flip cover cannot be kept stable in the closed state, and can be opened or tends to be opened due to the influence of factors such as product overturning and vibration, so that great trouble is brought to subsequent automatic assembly work. At present, the existing problem is generally ignored in the field of new energy automobile connectors, or a damper is used for delaying the automatic closing time of the flip, or a spring mechanism is added to enable the flip to be incapable of being opened automatically, but common methods in the industry cannot fundamentally solve the problems that the flip is not provided with a pre-stop position when being opened and the flip is not provided with a pre-stop position when being closed.

Detailed Description

The technical scheme of the patent is further described in detail below with reference to the specific embodiments.

In the description of the present utility model, it should be noted that the positional or positional relationship indicated by the terms such as "inner", "outer", "upper", "lower", "horizontal", etc. are based on the positional or positional relationship shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the apparatus or element in question must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

As shown in fig. 1 to 15, the present utility model provides a flip-type connector, which adopts a multi-stage flip structure. Specifically, the flip-type connector includes a hollow connector plug 10, and a connector receptacle 12 disposed within the connector plug 10. The connector plug 10 includes a housing 14, with an opening 16 for connection and a pin housing 18 provided in the housing 14.

A flip cover 20 is disposed at the opening 16, and the flip cover 20 is pivotally disposed on the pin seat 18 to close the opening 16. The flip cover 20 includes an integrally formed pivot portion 22 and a cover plate 24. The pivot portion 22 has a cylindrical structure, the second through hole is disposed along an axial direction thereof, and three limiting grooves 26 are disposed along the axial direction of the pivot portion 22. Three limit slots 26 limit the flip cover 20 to 0 °, 120 ° and 210 °.

The positioning spring plate 30 is arranged at the pin shaft seat 18 and is used for being clamped into the limiting groove 26 to prevent the flip cover 20 from rotating.

The pin holder 18 is provided with a first through hole (not shown) therethrough, the pivot portion 22 is provided with a second through hole (not shown) therethrough, and a pin 28 extends through the first and second through holes to connect the housing 14 and the flip cover 20. The pin 28 is fitted in the first and second through holes by riveting. This is a common pivot connection, although other forms of pivot connection may be used.

The positioning spring 30 is made of an elastic sheet, the positioning spring 30 has a protruding portion 32 protruding outward, the positioning spring 30 includes a first end 36 and a second end 38, and the protruding portion 32 is disposed near the first end 36 such that the protruding portion 32 abuts against the pivot portion 22. In its working principle, the positioning spring 30 is clamped between the flip cover 20 and the housing 14. When the flip 20 is turned over until the protruding part 32 is clamped into the limit groove 26, the protruding part 32 just prevents the flip 20 from continuing to turn over under the action of no external force, so that positioning is realized. If the operator continues to rotate the flip cover 20, the protruding portion 32 of the positioning spring plate 30 is stressed to be compressed and deformed inwards, so that the limit is released.

The second end 38 is folded inwardly and forms a flap 40 that is angled outwardly, and the housing 14 defines a recess 42, the flap 40 being disposed within the recess 42. The above structure is used for blocking the stop piece 40, i.e. the positioning spring piece 30, from falling outwards (i.e. upwards in the drawing) through the edge of the groove 42.

Further, a latch 44 is disposed on the flip cover 20, and a latch slot 46 for accommodating the latch 44 is disposed on the housing 14 corresponding to the latch 44. The latch 44 has a certain height, and when the latch 44 is snapped into the latch slot 46, it can prevent the latch 44 from being turned over and separated from the latch slot 46 in a natural state, thereby reducing the possibility of the flip cover 20 being opened naturally.

The clamping block 44 is provided with a locking hole 48, a threaded hole 54 is arranged in the clamping groove 46 corresponding to the locking hole 48, and the clamping block further comprises a locking screw 50 which can penetrate through the locking hole 48 and is in threaded connection with the threaded hole 54. The locking screw 50 is used to completely lock the flip cover 20 after the installation is completed.

The foregoing description is only illustrative of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structures or equivalent processes or direct or indirect application in other related technical fields are included in the scope of the present utility model.
