The upper surface of edge body is equipped with the second groove, and the spring base is fixed in second groove；Spring is equipped in the spring base to pacify
Hole is filled, the touch spring is installed in the spring mounting hole, and the spring mounting hole is fixed in the lower end of the touch spring
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.
As a further improvement of the present invention, the lower end of the pull rod is equipped with fixed positioning step and is connected through a screw thread
Locking nut, the upper end of the touch spring is locked between the positioning step and locking nut.
As a further improvement of the present invention, the upper port of the spring mounting hole is equipped with internal screw thread, with the locking screw
External screw thread on mother is cooperatively connected.
As a further improvement of the present invention, the polygonal head is hexagon-head.
As a further improvement of the present invention, first groove, the second groove and spring mounting hole are coaxially set.
As a further improvement of the present invention, the spring base, insulator and bolt are integrally formed by molding.
The beneficial effects of the present invention are: the Integral-type insulator, is designed as one end with spring base for insulator, one end is
The structure of bolt, touch spring are located among interior insulator spring base, are secured using the cooperation of locking nut and insulator
Touch spring and pull rod, meet insulator characteristic small in size, and the axial positioning of pull rod and bolt is to utilize pull rod and bullet
Spring, spring and spring base are worked in coordination, and the concentricity of pull rod and bolt is met, and reduce part quantity and part it is multiple
Miscellaneous processing technology.
Detailed description of the invention

Specific embodiment
Below in conjunction with attached drawing, elaborate to a preferred embodiment of the invention.But protection scope of the present invention is not
Be limited to following embodiments, i.e., in every case with simple equivalence changes made by scope of the present invention patent and description with repair
Decorations, all still belong within the invention patent covering scope.
It refering to fig. 1-2, is a kind of Integral-type insulator of the present invention, including insulator 1, bolt 2, spring base 3, touching
Head 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 it is more
The first groove 23 is machined on angle head, the lower end of the insulator is placed in first groove；The upper end of the insulator
Face is equipped with the second groove 11, and the spring base is fixed in second groove；Spring mounting hole 31, institute are equipped in the spring base
It states touch spring 4 to be installed in the spring mounting hole, and the bottom of the spring mounting hole is fixed in the lower end of the touch spring 4
Portion；The lower end activity of the pull rod is limited in the spring mounting hole and is fixedly connected with the upper end of the touch spring.
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.
