The upper surface of insulator is equipped with the second groove, and the spring base is fixed in second groove；Spring is equipped in the spring base
Mounting hole, the touch spring are installed in the spring mounting hole, and spring installation is fixed in the lower end of the touch spring
The bottom in hole；The lower end activity of the pull rod, which is limited in the spring mounting hole and fixes with the upper end of the touch spring, to be connected
It connects.
The lower end of the pull rod is equipped with fixed positioning step and passes through screw thread as a further improvement of the utility model,
The locking nut of connection, the upper end of the touch spring are locked between the positioning step and locking nut.
The upper port of the spring mounting hole is equipped with internal screw thread as a further improvement of the utility model, with the lock
External screw thread on tight nut is cooperatively connected.
The polygonal head is hexagon-head as a further improvement of the utility model,.
First groove, the second groove and spring mounting hole coaxial line are set as a further improvement of the utility model,
It sets.
The spring base, insulator and bolt are integrally formed by molding as a further improvement of the utility model,.
The beneficial effects of the utility model are: the Integral-type insulator, insulator is designed as one end with spring base, one
End is the structure of bolt, and touch spring is located among interior insulator spring base, solid using the cooperation of locking nut and insulator
Touch spring and pull rod are determined, have met insulator characteristic small in size, the axial positioning of pull rod and bolt is to utilize pull rod
With spring, working in coordination for spring and spring base meets the concentricity of pull rod and bolt, and reduce the quantity and zero of part
The processing technology of part complexity.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model section structural schematic diagram.
In conjunction with attached drawing, make the following instructions:
1 --- insulator；11 --- the second groove；

Specific embodiment
Below in conjunction with attached drawing, elaborate to a preferred embodiment of the utility model.But the guarantor of the utility model
Shield range is not limited to following embodiments, i.e., in every case with simple made by present utility model application the scope of the patents and description
Equivalent changes and modifications all still belong within the utility model patent covering scope.
It refering to fig. 1-2, is a kind of Integral-type insulator described in the utility model, including insulator 1, bolt 2, spring base
3, touch spring 4 and pull rod 5, the lower end of the bolt are with externally threaded screw rod 21, and upper end is polygonal head 22, the bolt
Polygonal head on be machined with the first groove 23, the lower end of the insulator is placed in first groove；The insulator
Upper surface is equipped with the second groove 11, and the spring base is fixed in second groove；Spring mounting hole is equipped in the spring base
31, the touch spring 4 is installed in the spring mounting hole, and the spring mounting hole is fixed in the lower end of the touch spring 4
Bottom；The lower end activity of the pull rod, which is limited in the spring mounting hole and fixes with the upper end of the touch spring, to be connected
It connects.
Wherein, the locking nut 52 that the lower end of the pull rod is equipped with fixed positioning step 51 and is connected through a screw thread, institute
The upper end for stating touch spring is locked between the positioning step and locking nut.The upper port of the spring mounting hole is equipped with interior
External screw thread on screw thread, with the locking nut is cooperatively connected.The polygonal head 22 is hexagon-head.First groove,
Second groove and spring mounting hole are coaxially set.The spring base, insulator and bolt are integrally formed by molding.
The Integral-type insulator placed spring base using the first recess space of bolt, lead between spring base and bolt
Spring base is connected mutually by the insulating materials i.e. insulator for crossing molding with bolt, can save volume and electrical
Insulation performance, in insulator manufacturing process, as long as using mold using the outer diameter of the external screw thread of bolt and pull rod as positioning,
It is able to satisfy the concentricity of two parts, and other processing dimensions do not influence the concentricity of part.
Touch spring is placed among the spring base of interior insulator, the inner hole of spring base to the outer diameter of touch spring into
Gone the positioning of concentricity, the inner hole with positioning step and touch spring is positioned on pull rod, recycle locking nut and
The screw thread of spring base oral area is worked in coordination, and touch spring is fixed on interior insulator while securing connecting rod, this structure will
Original multiple component bodies are combined into single component body, since the concentricity of insulator ensures, pull rod, touch spring, bullet
Spring abutment is worked in coordination, so that the component is not necessarily to any positioning fixture in assembling process, need to only be assembled all spare and accessory parts
It is just able to satisfy the requirement of the concentricity of component entirety together.
In addition, being outer-hexagonal structure on the outside of the Integral-type insulator, reduces and needed in the connection procedure of galvanic circle
The locking of nut, it is only necessary to bolt be screwed in the screw thread for needing to cooperate on connector, directly insulation and connector can be carried out
It is fixedly connected.
It can be seen that the Integral-type insulator, is designed as one end with spring base for insulator, one end is the knot of bolt
Structure, touch spring are located among interior insulator spring base, secure touch spring using the cooperation of locking nut and insulator
And pull rod, meet insulator characteristic small in size, the axial positioning of pull rod and bolt be using pull rod and spring, spring with
Spring base is worked in coordination, and the concentricity of pull rod and bolt is met, and reduces the processing of the quantity and part complexity of part
Technique.
