Description
Technical field
The utility model relates to a kind of lock-on connection, and particularly a kind of cable seal lock-on connection with insulating property, belongs to interconnection technique field.
Background technology
Usually harmonic pollution can be there is in electrical network, need bank of filters to filter out the harmonic wave in electrical network, operating voltage is all higher under normal circumstances to be wherein positioned at the mutual inductor of wave filter head end, Signal transmissions gets off by the usual employing optical fiber of head end wave filter sensing head, this segment signal optical fiber between sensing head and insulator prop up can not direct naked leakage outside, consider that the harsh environment of outdoor use adopts corrugated stainless steel tubing guard signal line under normal circumstances, adopt corrugated stainless steel tubing also can produce certain drawback, the electric current of bank of filters can be gone over by corrugated stainless steel tubing transmission, create the current path outside filter measurement coil, thus reduce the measuring accuracy of wave filter mutual inductor.Simultaneously the running environment of wave filter sensing head top measurement mechanism also requires to reach air-proof condition under condition out of doors, therefore need to carry out sealing and insulation processing at the fairlead of sensing head signal optical fibre, and the lock-on connection of common plastic material is easy to aging under long-term outdoor service condition, cannot ensure normal life cycle, therefore this just proposes durable requirement to the cable lock tight coupling being applied to wave filter sensing head side under sealing and insulation situation.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of cable seal lock-on connection with insulating property, the sealing of joint is realized by O RunddichtringO, achieve locking to cable and sealing by the rubber ring of cable lock sleeve and its inside, effectively solve the problem in background technology.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
A kind of cable seal lock-on connection with insulating property of the utility model, comprise lock-on connection and the X-over being threaded connection lock-on connection, described lock-on connection both sides all have the seal groove placing O RunddichtringO, described lock-on connection inside is provided with cable lock sleeve, and described cable lock sleeve inside is provided with rubber sleeve.
As a kind of optimal technical scheme of the present utility model, described lock-on connection is the lock-on connection of copper nickel plating material, and described lock-on connection inside is the forge piece of step type structure cooperatively interacted with the profile of cable lock sleeve.
As a kind of optimal technical scheme of the present utility model, described cable lock sleeve is the cable lock sleeve of nylon material, and one end of described cable lock sleeve is provided with deformable locking jaw.
As a kind of optimal technical scheme of the present utility model, described X-over is the X-over of epoxy material DFL202 material, and there is a reducing inclined-plane inside of described X-over, the angle of this inclined-plane and horizontal axis is greater than the locking jaw of cable lock sleeve and the angle of horizontal axis.
The beneficial effect that the utility model reaches is:
1, lock-on connection adopts the material of copper nickel plating, and X-over adopts epoxy material DFL202, material functional, meets long-term outdoor and uses requirement without the need to changing.
What 2, X-over adopted is isolation material, thus has cut off the current path of corrugated stainless steel tubing, ensure that the measuring accuracy of wave filter.
3, all have the seal groove placing O RunddichtringO in the both sides of lock-on connection, realized the sealing of lock-on connection by O RunddichtringO.
4, the rubber ring of its inside is made to shrink the locking and sealing realized cable by the extruding of X-over to cable lock sleeve.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for instructions, is used from explanation the utility model, does not form restriction of the present utility model with embodiment one of the present utility model.
In the accompanying drawings:
Fig. 1 is a kind of inner structure schematic diagram with the cable seal lock-on connection of insulating property described in the utility model embodiment;
Fig. 2 is a kind of structural representation with the cable seal lock-on connection of insulating property described in the utility model embodiment;
Number in the figure: 1, lock-on connection; 2, O RunddichtringO; 3, cable lock sleeve; 4, rubber sleeve; 5, X-over; 6, locking jaw.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
Embodiment: as shown in Figure 1, a kind of cable seal lock-on connection with insulating property of the utility model, comprise lock-on connection 1 and the X-over 5 being threaded connection lock-on connection 1, described lock-on connection 1 both sides all have the seal groove placing O RunddichtringO 2, described lock-on connection 1 inside is provided with cable lock sleeve 3, and described cable lock sleeve 3 inside is provided with rubber sleeve 4.
Side, lock-on connection 1 both sides has seal groove, realizes by O RunddichtringO 2 sealing that X-over 5 is connected with lock-on connection 1; Lock-on connection 1 is the lock-on connection 1 of copper nickel plating material, material functional, meets long-term outdoor and uses requirement without the need to changing; And the inside of lock-on connection 1 is forge piece of step type structure, realization identical with the profile of cable lock sleeve 3 cooperatively interacts.
Cable lock sleeve 3 is the cable lock sleeve 3 of nylon material, and one end of cable lock sleeve 3 is provided with deformable locking jaw 6, the internal diameter of cable lock sleeve 3 can be made to change within the specific limits by changing the power acted on cable lock sleeve 3, simultaneously also have a rubber sleeve 4 in the inside of cable lock sleeve 3, locking to cable and sealing can be realized by the contraction of cable lock sleeve 3.
X-over 5 is the X-over 5 of epoxy material DFL202 material, realizes the insulating property of whole lock-on connection under the prerequisite of proof strength; And there is a reducing inclined-plane inside of X-over 5, the angle of this inclined-plane and horizontal axis is greater than the locking jaw 6 of cable lock sleeve 3 and the angle of horizontal axis, therefore when X-over is screwed into lock-on connection 1, first the path of X-over 5 contacts with the locking jaw 6 of cable lock sleeve 3, and further rotating along with X-over 5, the locking jaw 6 pressure increase of X-over 5 pairs of cable lock sleeves 3 makes the internal diameter of cable lock sleeve 3 diminish, and is locked by rubber sleeve 4 pairs of cables of cable lock sleeve 3 inside and is sealed.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although be described in detail the utility model with reference to previous embodiment, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
