Description
Technical field
This utility model relates to the connection production technical field of spark gap and wire, a kind of spark gap of concrete offer and wire
Attachment means.
Background technology
Spark gap is widely used in distribution transformer, on-load switch and other distribution facilities, and circuit arrangement is played guarantor
Protect effect.Spark gap is generally connected between wire and the earth, is in parallel with protected equipment.During use, spark gap handle
The instantaneous overvoltage of transmission line is limited in the voltage range that equipment can bear, or powerful thunder-strike current is introduced the earth,
Make protected equipment without damage.After the voltage of transmission line is normal, spark gap restores to the original state rapidly, system normal power supply.
In prior art, in the wire being connected with spark gap, be substantially hard copper wire because the hard wire of same cross-sectional area with
Soft wire is compared, and has the advantage that anti-current performance is strong and cheap, so spark gap manufacturing enterprise all uses firmly mostly
Matter copper conductor is connected with spark gap.Because spark gap lower end electrode is connected with hard copper wire by stud, copper is led
The line nose of line cannot use at all, by being holed by stud, then can only be crimped in stud bolt hole by core after copper conductor peeling,
By the way of crimping, copper conductor is connected with spark gap.After copper conductor peeling, core is crushed in stud, so connects non-
The most firmly, but, in work progress, copper conductor doubling repeatedly bending is easy to the core drop making to leak outside, and causes spark gap
Good connection can not be kept with copper conductor, make spark gap can not play due effect in the case of overvoltage, thus make
Become danger, bring immeasurable loss to enterprise.
Summary of the invention
In order to solve with present on problem, this utility model provides a kind of structure design advantages of simple, can be by spark gap
Together with being securely attached to copper conductor, and the attachment means of the spark gap that is not easily broken of copper conductor core and wire.
For achieving the above object, this utility model provides following technical scheme:
A kind of spark gap and the attachment means of wire, be made up of stud and fixed cover, and described stud offers for accommodating
The axially extending bore of copper conductor core；Fixed cover one end offers the holding tank for accommodating copper conductor, the fixed cover other end and spiral shell
Male screw connects.
Described fixed cover uses metal material to make, and selects metallic copper or metallic aluminium to be prepared from this utility model.
During use, the female thread of fixed cover matches with the external screw thread of stud, is threadeded with stud by fixed cover.
The insulating barrier of copper conductor one end is removed, spills core, core is fully absorbed within the axially extending bore of stud.Now, do not go
Except the copper conductor of insulating barrier is deep in holding tank.By External Force Acting by core and and do not remove insulating barrier copper conductor compress
In fixed cover.Because core and the copper conductor not removing insulating barrier are all crimped in fixed cover, copper conductor stress in construction
Position, at insulating barrier, the most well protects hard core and is not fractureed by external force.
As preferably, the length of described holding tank accounts for the 2/5-3/5 of fixed cover total length, it is ensured that be deep into holding tank
In the length of copper conductor, it is ensured that in work progress, force part is at insulating barrier, can well protect core.
As preferably, the diameter of described holding tank is slightly larger than the diameter of copper conductor, and both are that gap closely cooperates, it is ensured that execute
During work, force part is on the insulating barrier of copper conductor.
As preferably, 1-1.2 times of a diameter of copper conductor wire core diameter of described axially extending bore.The diameter of axially extending bore is slightly
More than the diameter of copper conductor core, conveniently copper conductor core is deep in axially extending bore, improves work efficiency.
Compared with prior art, spark gap of the present utility model has useful effect highlighted below with the attachment means of wire
Really:
(1) spark gap described in the utility model and the attachment means of wire are by core and the copper conductor not removing insulating barrier
All being crimped in fixed cover, be connected firmly, in work progress, copper conductor force part is on insulating barrier rather than core, this
Sample the most well protects core and is not fractureed by external force, adds the service life of copper conductor, it is ensured that the normal work of spark gap
Make, the generation reduced risks, and save entreprise cost；
(2) described fixed cover uses copper sheathing or aluminum set, and its material source is extensive, cheap, use process to environment without
Pollute, there is good practicality.

Fig. 1 is the structural representation of stud described in the utility model；
Fig. 2 is the structural representation of aluminum described in the utility model set；
Fig. 3 is the structural representation of copper conductor described in the utility model；
Fig. 4 is the use structural representation of spark gap described in the utility model and the attachment means of copper conductor.
Wherein, 1. stud, 2. aluminum set, 3. axially extending bore, 4. copper conductor, 5. core, 6. holding tank.
Detailed description of the invention
Below in conjunction with drawings and Examples, the attachment means of a kind of spark gap of the present utility model Yu wire is made into one
Step describes in detail.
In this utility model, in the case of illustrating on the contrary, the noun of locality of use such as " upper and lower, left and right " is usual
Refer to reference to upper and lower, left and right shown in the drawings；It is inside and outside that " inside and outside " refers to relative to the profile of each parts itself.
Embodiment
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, spark gap of the present utility model and the attachment means of wire are mainly by stud 1
With aluminum set 2 composition.Stud 1 offers axially extending bore 3,1.1 times of core 5 diameter of a diameter of copper conductor 4 of axially extending bore 3,
For accommodating core 5.Aluminum overlaps 2 one end and offers the holding tank 6 for accommodating copper conductor 4, and a length of aluminum set 2 of holding tank 6 is long
The 1/2 of degree.The diameter of holding tank 6 is slightly larger than the diameter of copper conductor 4, and both are that gap closely cooperates.Aluminum overlaps 2 other ends and stud
1 is threaded.
Spark gap of the present utility model with the use process of the attachment means of wire is: with stud 1, aluminum set 2 is passed through screw thread
Fixing connection；The insulating barrier of copper conductor one end is removed, spills core 5, core 5 is fully absorbed within the axially extending bore 3 of stud 1
In；Now, during copper conductor 4 is deep into holding tank 6；By External Force Acting, core 5 and copper conductor 4 are pressed in aluminum set 2.
Core 5 and the insulating barrier of copper conductor 4 is all crimped in aluminum set 2, and in construction, copper conductor 4 force part is in insulation
Layer, the most well protects core 5 not because being fractureed by external force.
Embodiment described above, simply this utility model more preferably detailed description of the invention, those skilled in the art
The usual variations and alternatives carried out in the range of technical solutions of the utility model all should be included in protection domain of the present utility model
In.
