Abstract
The utility model provides an external conical insulation cap with bosses and connecting screws, and mainly solves the problems of occurrence of a gap, complicated structure and high cost caused by loose connection between an existing external conical insulation cap and an external conical sleeve tube. The external conical insulation cap with the bosses and the connecting screws comprises a shielding sleeve which is fixedly arranged in an insulation layer, wherein the inwall of the insulation layer is provided with bosses, and screws and lugs are symmetrically arranged on the outer side of the insulation layer. The external conical insulation cap with the bosses and the connecting screws greatly increases the connection strength by adopting the clamping connection manner, and does not come off from the external conical sleeve tube during the harsh using process; the external conical insulation cap with the bosses and the connecting screws has high reliability and simple structure; meanwhile, in order to further improve the connecting strength, the connecting screws are additionally arranged on the basis of the bosses by the external conical insulation cap.
Description
Technical field
The utility model relates to a kind of outer cone insulator cap.
Background technology
Existing outer cone insulator cap generally directly is socketed on the outer cone sleeve pipe, because external conical sleeve tube-surface fineness is higher, and there is certain taper, be in place shed external force after, the outer cone insulator cap may outwards slide from the outer cone sleeve pipe, thereby cause contacting not tight between the two, the slit occurs, affect the insulation coordination between the two.
In order to solve this technical problem, those skilled in the art adopt the housing in the outer cone insulator cap are processed as screw thread form, be threaded connection assurance bonding strength between the two, existing housing is two kinds of versions, the machine-shaping of a kind of employing metal, and the bonding strength between metallic shield cover and the rubber insulation sleeve is lower, so when mounted, radial effect power cause easily housing and the outer cone insulator cap between tear, thereby can't install; Another kind of adopt conductive rubber, although conductive rubber has solved the problem of easily tearing between the housing and outer cone insulator cap in the installation process, this version is also difficulty comparatively of complexity and the processing of shape of threads housing comparatively; Simultaneously, the mode that is threaded may be become flexible owing to the reasons such as vibrations cause connecting, thereby has caused the generation of security incident.
Summary of the invention
The utility model provides a kind of outer cone insulator cap with boss and connecting screw rod, has mainly solved to be connected between existing outer cone insulator cap with boss and connecting screw rod and the outer cone sleeve pipe closely not to be prone to the slit, complex structure, the problem that cost is high.
Technical solution of the present utility model is:
This outer cone insulator cap with boss and connecting screw rod comprises the housing that is fixedly installed in the insulating barrier, integral piece is processed in insulating barrier and housing sulfuration, be provided with the outer cone sleeve pipe suitablely on the described insulating barrier inwall, be used for the parallel boss of at least two groups of clamping Anti-extrusion; Described and chase after the nearest boss of insulator cap openend outward and chase after distance position a 10 ~ 20mm between the insulator cap openend outward, boss top rounding; The described insulating barrier outside is symmetrically arranged with at least two ear seats that are used for screw rod connecting band screwed hole, screw rod one end is connected with the ear seat in the insulating barrier outside, the screw rod other end is connected with the ear seat that is arranged on the outer cone outside of sleeve, should be parallel to the insulating barrier central shaft with the line of centres of the suitable outer cone sleeve pipe ear seat of insulating barrier ear seat;
Above-mentioned boss is three groups, and equal difference distributes between each group, the distance between per two groups of boss be housing high 1/5 ~ 1/4.
Above-mentioned insulating barrier arranged outside has screen.
The utility model advantage is:
This owing to adopted the connected mode of clamping, has greatly improved bonding strength, with the outer cone insulator cap of boss and connecting screw rod in abominable use procedure, as can from the outer cone sleeve pipe, not deviating from the vibration environment yet, reliability is high, and simple in structure, processing cost is low.Simultaneously, in order further to improve bonding strength, this outer cone insulator cap with boss and connecting screw rod has also increased connecting screw rod on the basis of boss.
Description of drawings
Fig. 1: structural representation of the present utility model.
Wherein: the 1-boss; The 2-insulating barrier; 3-ear seat; The 4-screw rod; The 5-housing;
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail, as shown in Figure 1:
This outer cone insulator cap with boss and connecting screw rod comprises the housing 5 that is fixedly installed in the insulating barrier 2, insulating barrier 2 is processed into integral piece with housing 5 sulfurations, be provided with the outer cone sleeve pipe suitablely on insulating barrier 2 inwalls, be used for the parallel boss 1 of at least two groups of clamping Anti-extrusion; And chase after the nearest boss of insulator cap openend 1 outward and chase after distance position a 10 ~ 20mm between the insulator cap openend outward, boss 1 top rounding.
In order further to improve bonding strength, the utility model has increased connecting screw rod 4, insulating barrier 2 outsides are symmetrically arranged with at least two ear seats that are used for screw rod 4 connecting band screwed holes, screw rod 4 one ends are connected with the ear seat in insulating barrier 2 outsides, screw rod 4 other ends are connected with the ear seat 3 that is arranged on the outer cone outside of sleeve, should be parallel to insulating barrier 2 central shafts with the line of centres of the suitable outer cone sleeve pipe ear seat 3 of insulating barrier 2 ear seats 3;
During use, need outside with this, to chase after the suitable outer cone sleeve position corresponding position of insulator cap and set up groove, in the installation process, only need the outer cone sleeve pipe is directly pushed outer chasing after in the insulator cap, and boss 1 is snapped in the groove get final product, after the installation, again screw rod 4 is connected on the ear seat 3, and regulate by screw thread, further improve bonding strength, prevent from coming off.
