Description
Technical field
The present invention relates to electrical connector, and in particular to wire clamp.
Background technology
The wire clamp of wire rod, such as wire clamp of the electronic product for clamping wire termination, typically use shell fragment wire gripper, institute
Shell fragment is stated after being repeatedly used for a long, elastic force is tired, and wire rod is easy to fall off.
The content of the invention
Technical problem solved by the invention：How stability that wire clamp fix wire rod is improved.
In order to solve the above technical problems, the present invention provides following technical scheme：A kind of wire clamp, by Trap shell splinter and support base
Composition；The support base is provided with support shaft, and the lower section of support shaft is insert port；The Trap shell splinter is in back-shaped, is centered around described
In support shaft, for depressing being plugged in the wire rod to insert into the mouth.
By above-mentioned technical proposal, back-shaped Trap shell splinter, its bent portion is centered around in the support shaft, with the support
Axle is fulcrum, and the Trap shell splinter duplicates in lever.The top of Trap shell splinter is pressed, Trap shell splinter rotates around support shaft, folder
The bottom of line shell fragment pushes wire rod, and wire rod is clamped between the bottom of Trap shell splinter and support base.
The support base is provided with bottom plate, and the insert port is located at the left side of bottom plate, mating holes is opened up on the bottom plate；Clamp
The both ends of shell fragment are respectively line ball end and pressing end, and the line ball end is positioned in the mating holes.In wire clamp not
During wire gripper, in the raw, its line ball end has certain tension force to the Trap shell splinter, and is pressed on matching somebody with somebody for bottom plate
Close in hole, the cooperation for making Trap shell splinter be stablized with support base, form an overall structure, entitled wire clamp.
The right side of the bottom plate is provided with riser, and riser is provided with the first engaging support mechanism, and the pressing end is provided with can be with
The second engaging support mechanism that first engaging support mechanism coordinates.Press the pressing end of Trap shell splinter, the line ball end of Trap shell splinter
Wire rod is pushed, at the same time, first engaging support mechanism coordinates with second engaging support mechanism, makes at Trap shell splinter pressure holding wire rod
In hold mode.
The preferably following two designs of structure of above-mentioned first engaging support mechanism and the second engaging support mechanism：
The first of first engaging support mechanism and the second engaging support mechanism design are as described below.First engaging support mechanism is downward
First bending piece of bending, the first bending piece are located at the inner side of riser, and second engaging support mechanism is the second folding of upward bending
Bending.Because the first bending piece and the second bending piece form through Bending Processing, therefore, both of which is flexible, in Trap shell splinter
Press-side subordinate pressure in the case of, micro elastic deformation can occur and snap together.Wherein, the riser is provided with
First moves back line driving lever, and first moves back line driving lever and the first bending piece Integral design, presses down on described first and moves back line driving lever, institute
The first bending piece is stated to upwarp, around support shaft rotate the pressing end away from the first bending piece and with the first bending piece
Depart from, line is moved back with complete wire rod.
Second of design of the first engaging support mechanism and the second engaging support mechanism is as described below.First engaging support mechanism is to open up
Square orifice on the riser, second engaging support mechanism is by the buckle in the dogleg section and the dogleg section of pressing end
Composition, the buckle are located at the inner side of the dogleg section, press down on the pressing end, and the buckle is fastened on the side
In shape mouth.In the case of the press-side subordinate pressure of Trap shell splinter, the inner side of the dogleg section and the contact outside of riser, folding
Elastic deformation occurs for bight portion, and buckle is descending along the lateral wall of riser, until being fastened in the square orifice, to lock clamp bullet
Piece.Wherein, line driving lever is moved back in the end of the dogleg section provided with second, second move back line driving lever by the dogleg section bending and
Into.Described second is stirred laterally and moves back line driving lever, and the buckle departs from square orifice, and line is moved back with complete wire rod.
The present invention utilizes lever principle, Trap shell splinter is produced one very big push to the wire rod for inserting the insert port
Power, prevent it from releasing.When moving back line, stir move back line driving lever (above-mentioned first moves back line driving lever or second move back line driving lever) make Trap shell splinter and
Engaging support mechanism on support base releases, simple to operate and facilitate.Wherein, Trap shell splinter uses back-shaped structure design, is not easy tired.
