Description

Flip integrated two-stage locking structure of energy storage connector

Technical Field

The present utility model relates to an electrical connector, and more particularly, to a latch structure of an electrical connector.

Background

The lock catch of the plug uses the pressing handle to press the spring to bear force, so that the primary lock catch is displaced and separated from the socket hook. When the socket is locked, the pressing force acting on the pressing handle is removed, the spring acts on the pressing handle, the pressing handle limits the primary lock catch, and the matching of the primary lock catch and the socket hook is locked. The product is protected by a secondary locking mechanism, and the primary locking has failure risk. For this purpose, the plug is provided with a secondary lock. The secondary locking part needs to be installed on the plug, which is not beneficial to the improvement of the production efficiency of the product, and the secondary locking part needs to be produced in addition, which is not beneficial to the reduction of the production cost of the whole product.

Disclosure of Invention

The technical problems solved by the utility model are as follows: how to reduce the amount of the product parts and reduce the production cost.

In order to solve the technical problems, the utility model provides the following technical scheme: the utility model provides an energy storage connector flip integral type secondary hasp structure, includes the secondary hasp piece of tail end and plug body coupling, and the head end of secondary hasp piece is equipped with spacing fin, and spacing fin can offset with one-level hasp handle, makes one-level hasp handle unable the pressing unblock, and the tail end and the plug body integrated into one piece of secondary hasp piece, and the tail end of secondary hasp piece is equipped with semicircle disjunctor formula structure.

After the plug is inserted into the socket, the connection point of the primary lock catch of the plug is stressed and deformed, so that the clamping hook of the primary lock catch and the clamping hook of the socket are locked. The secondary locking piece is turned anticlockwise, so that the limiting convex rib of the secondary locking piece is propped against the primary locking handle. Because the primary lock handle is limited, the primary lock handle cannot be pressed to unlock.

When unlocking, the secondary locking piece is turned clockwise, so that the limiting convex rib of the secondary locking piece is separated from the primary locking handle, and at the moment, the secondary locking piece is unlocked. After the unlocking of the second-level locking piece is completed, the first-level locking handle is pressed, so that the connecting point of the first-level locking is stressed to deform, further, the locking hook of the first-level locking is separated from the locking point of the socket, and finally, the plug is pulled out of the socket.

The utility model is an integrated secondary locking piece with the plug body, and is matched with the primary locking piece for use, thereby reducing the manufacturing and assembling cost of parts. The two lock catch structures are matched for use, so that the lock catch grade is improved, and the quality of a product is further improved.

The semicircular arc integrated structure at the tail end of the secondary locking piece is located at the joint of the secondary locking piece and the plug body, has an elastic function, is convenient for the secondary locking piece to turn over, can effectively avoid breakage of the secondary locking piece due to multiple turning over, and is also convenient for the limiting convex rib on the secondary locking piece to prop against the primary locking handle.

The plug body is provided with a groove structure, the primary lock catch handle is located in the groove structure, and the limiting convex rib can be clamped into the groove structure to prop against the primary lock catch handle. When the locking is performed, the secondary locking piece is turned anticlockwise, so that the limiting convex rib of the secondary locking piece is pressed into the groove structure to limit with the primary locking handle.

Two ends of the head end of the secondary locking piece are provided with cylindrical convex ribs, two sides of the groove structure are provided with convex walls, the convex walls are provided with U-shaped limiting grooves, the secondary locking piece can be matched between the pair of convex walls, and the cylindrical convex ribs can be matched with the U-shaped limiting grooves.

During locking, the secondary locking piece is turned anticlockwise, so that the cylindrical convex rib is pressed into the U-shaped limiting groove in an interference mode to limit and lock, and meanwhile, the limiting convex rib of the secondary locking piece abuts against the primary locking handle. When unlocking, the secondary locking piece is turned clockwise, so that the cylindrical convex ribs on two sides of the secondary locking piece are separated from the U-shaped limiting groove, and meanwhile, the limiting convex ribs of the secondary locking piece are separated from the primary locking handle.

Detailed Description

Referring to fig. 1 and 4, the flip integrated secondary locking structure of the energy storage connector comprises a secondary locking piece 20 with a tail end connected with a plug body 10, wherein a limiting convex rib 21 is arranged at the head end of the secondary locking piece and can abut against a primary locking handle 31, so that the primary locking handle cannot be pressed to be unlocked, the tail end of the secondary locking piece and the plug body are integrated into one, and a semicircular arc integrated structure 22 is arranged at the tail end of the secondary locking piece.

The plug body 10 is provided with a groove structure, the primary locking handle 31 is located in the groove structure, and the limiting convex rib 21 can be clamped into the groove structure to abut against the primary locking handle.

The both ends of second grade hasp piece 20 head end are equipped with cylinder fin 23, and groove structure both sides are equipped with the convex wall, are equipped with U type spacing groove 11 on the convex wall, and the second grade hasp piece can cooperate between a pair of convex wall, and the cylinder fin can cooperate with U type spacing groove.

Referring to fig. 3 and 4, after the plug is inserted into the socket 40, the primary latch connection point 32 of the plug is deformed by force, so that the hook 33 of the primary latch is locked with the hook of the socket. The secondary locking piece 20 is turned anticlockwise, so that the cylindrical convex rib 23 is pressed into the U-shaped limiting groove 11 in an interference manner to limit and lock. At the same time, the limit ribs 21 of the secondary latch are made to abut against the primary latch handle 31. The primary latch handle 31 is limited, so that the primary latch handle cannot be pressed to unlock.

Referring to fig. 5 to 7, when unlocking, the secondary locking member 20 is turned clockwise to separate the cylindrical ribs 23 on both sides of the secondary locking member from the U-shaped limiting groove 11, and simultaneously, the limiting ribs 21 of the secondary locking member are separated from the primary locking handle 31, and at this time, the secondary locking member is unlocked. After the secondary lock catch piece 20 is unlocked, the primary lock catch handle 31 is pressed to deform the primary lock catch connection point 32 under force, further, the primary lock catch hook 33 is separated from the socket 40 in a locking way, and finally the plug is pulled out of the socket 40.

The foregoing is merely illustrative of the preferred embodiments of the present utility model, and modifications in detail will readily occur to those skilled in the art based on the teachings herein without departing from the spirit and scope of the utility model.
