Abstract
The utility model discloses a fixing fastener structure for with electric connector and the mutual fixed connection of PCB board, it includes the buckle physically, buckle body top is equipped with the buckle step, the chucking groove has been offered to the top orientation in the bottom of the buckle body, makes buckle body bottom forms elasticity bayonet catch portion, two outside limits of elasticity bayonet catch portion bottom are equipped with the arch respectively, be equipped with engagement groove between arch and the buckle step. The compressible deformation of elasticity bayonet catch portion under the extrusion of external force, pass the PCB board and electric connector goes up the mounting hole that corresponds each other with elasticity bayonet catch portion, cancels the back in external force, and elasticity bayonet catch portion reconversion makes the engagement groove block on PCB board and electric connector in the mutual mounting hole that corresponds, its simple structure, convenient to use has improved fixed mounting work efficiency.
Description
Technical field
This utility model relates to fixed installation field, particularly to the fixing buckle structure of one.
Background technology
At present, when electric connector is arranged on pcb board, great majority are both to be interfixed by bolt, screw, or by rivet, electric connector is fixed on pcb board, adopting above-mentioned fixed form to fix, there is following shortcoming: fastener-parts is many, cost is high; For needs secondary installing, its operation is loaded down with trivial details, fastens inefficiency; Locking direction is reversely, not easily operates.
Utility model content
This utility model provides one fixing buckle structure, it is therefore intended that provide a kind of fastening buckle structure being easily installed dismounting.
This utility model provides one fixing buckle structure, for electric connector and pcb board are mutually permanently connected, it includes buckling body, described buckling body top is provided with buckle step, the bottom of described buckling body offers clamping slot to top-direction, making formation elastic card buckle portion bottom described buckling body, described elastic card buckle portion bottom two outer side edges is respectively equipped with projection, is provided with and engages groove between described projection with buckle step.
Further, described buckling body is platy structure, is made up of rustless steel, phosphor-copper or pyrite.
This utility model has the beneficial effect that: adopt this novel fixing buckle structure, by being provided with clamping slot bottom buckling body, make formation elastic card buckle portion bottom buckling body, elastic card buckle portion bottom two outer side edges is equipped with projection, buckling body top is provided with buckle step, projection engages groove with being provided with between buckle step, the compressible deformation of elastic card buckle portion under the extruding of external force, by elastic card buckle portion traverse pcb board and installing hole mutually corresponding on electric connector, after external force is cancelled, elastic card buckle portion restores to the original state, make engaging groove be fastened on pcb board with in installing hole mutually corresponding on electric connector. its simple in construction, easy to use, improve fixed installation work efficiency.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of fixing buckle structure of this utility model;
In figure, 1-buckling body, 2-clamping slot, 3-elastic card buckle portion, 31-is protruding, and 32-engages groove, 4 buckle steps.
Detailed description of the invention
Below in conjunction with Figure of description, this utility model embodiment is described in further detail.
As shown in Figure 1, this utility model provides one fixing buckle structure, for electric connector and pcb board are mutually permanently connected, it includes buckling body 1, in the present embodiment, there is choosing, buckling body 1 is the rustless steel of plate body, phosphor-copper or pyrite punch forming, buckling body top is provided with buckle step 4, the bottom of buckling body 1 offers clamping slot 2 to top-direction, elastic card buckle portion 3 is formed on the bottom making buckling body 1, and bottom two outer side edges of elastic card buckle portion 3 is respectively equipped with protruding 31, is provided with and engages groove 32 between protruding 31 and buckle step 4.
When fixed installation uses, first elastic card buckle portion 3 is applied external force, the two edges compression of elastic card buckle portion 3 is drawn close, make the distance between two projections 31 less than pcb board and the installing hole internal diameter on electric connector, elastic card buckle portion 3 bottom is after installing hole, cancel externally applied forces, protruding 31 under the elastic force of elastic card buckle portion 3, restore to the original state, when original state, the distance between two protruding 31 outer surfaces is more than pcb board and the installing hole internal diameter on electric connector, distance between two buckle step 4 outer ledges is more than pcb board and the installing hole internal diameter on electric connector, distance between two engaging groove 32 outer surfaces is not more than pcb board and the installing hole internal diameter on electric connector, the width of engaging groove 32 is equal to the degree of depth of the installing hole on pcb board and electric connector, when dismounting, to applying bottom external force elasticity of compression clamping part 3 bottom elastic card buckle portion 3, make the distance between two projections 31 less than pcb board and the installing hole internal diameter on electric connector, in installing hole, take out buckling body 1.
Obviously, this utility model can be carried out various change and modification without deviating from spirit and scope of the present utility model by those skilled in the art. So, if these amendments of the present utility model and modification belong within the scope of this utility model claim and equivalent technologies thereof, then this utility model is also intended to comprise these change and modification.
Claims (2)
