Abstract
The utility model provides an external conical insulation cap with bosses, 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 comprises a shielding sleeve which is fixedly arranged in an insulation layer, wherein the inwall of the insulation layer is provided with at least two groups of parallel bosses which are matched with the external conical sleeve tube for clamping and loose preventing; and the distance between the boss, which is closest to an opening end of the external conical insulation cap, and the opening end of the external conical insulation cap with the bosses ranges from 10mm to 20mm, and the top parts of the bosses are chamfered. The external conical insulation cap with the bosses greatly increases the connection strength by adopting the clamping connection manner, does not come off from the external conical sleeve tube during harsh using process such as in a vibration environment; and has low manufacturing cost.
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 causes tearing between housing and the outer cone insulator cap easily, thereby can't install; Another kind of adopt conductive rubber, although conductive rubber has solved in the installation process housing and chased after the problem of easily tearing between the insulator cap outward, 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, has mainly solved to be connected between existing outer cone insulator cap with boss 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 comprises the housing that is fixedly installed in the insulating barrier, and insulating barrier is processed into integral piece with the housing sulfuration, be provided with the outer cone sleeve pipe on the described insulating barrier inwall suitable, for the parallel boss of at least two groups of clamping Anti-extrusion; Described and with the nearest boss of the outer cone insulator cap openend of boss and with the distance position 10 ~ 20mm between the outer cone insulator cap openend of boss, boss top rounding.
Above-mentioned boss is three groups, and equal difference distributes between each group, the distance between per two groups of boss 1 be housing high 1/5 ~ 1/4.
Width 5 ~ the 10mm of above-mentioned boss highly is 3 ~ 5mm.
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 in abominable use procedure, as also can not deviating from from the outer cone sleeve pipe in the vibration environment, reliability is high, and simple in structure, processing cost is low.
Description of drawings
Fig. 1: structural representation of the present utility model.
The accompanying drawing detail is as follows: the 1-boss; The 2-insulating barrier; The 3-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 comprises the housing 3 that is fixedly installed in the insulating barrier 2, insulating barrier 2 is processed into integral piece with housing 3 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 with the nearest boss 1 of the outer cone insulator cap openend of boss and with the distance position 10 ~ 20mm between the outer cone insulator cap openend of boss, boss top rounding.
Above-mentioned insulating barrier 2 arranged outside have screen.
During use, need setting up boss 1 with this with the suitable outer cone sleeve position corresponding position of the outer cone insulator cap of boss, in the installation process, only the outer cone sleeve pipe directly need be pushed in the outer cone insulator cap with boss, and boss 1 is snapped in get final product in the groove, boss 1 should adopt electro-insulating rubber or other that flexible insulation material is arranged, and has so both guaranteed the bonding strength after the installation, be not prone to the slit, so that when the needs such as maintenance or replacing take out the outer cone sleeve pipe, be convenient to extract yet.
