Abstract
The utility model provides an external cone insulating cap with a groove connecting screw rod and a pressure sensor, and mainly solves problems that connection of an existing external cone insulating cap and an external cone casing is not tight and gaps are easy to occur, work personnel can just determine connection degree through experience, reliability is poor, and structure is complex and cost is high. The external cone insulating cap with the groove connecting screw rod and the pressure sensor comprises a shielding sleeve disposed in an insulating layer. An inner wall of the insulating layer is provided with an anti-off groove. The inner wall of the insulating layer is provided with the pressure sensor. An outer wall of the insulating layer is provided with a display device. Screws and support lugs are symmetrically disposed outside the insulating layer. Since the external cone insulating cap with the groove connecting screw rod and the pressure sensor uses a connection type of clamping, connection strength is greatly improved, and meanwhile the connecting screw rod, the pressure sensor, and the display device are added, so that staff can conveniently and visually determine connection state on site.
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 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 groove connecting screw rod and pressure sensor, mainly solved to be connected between existing outer cone insulator cap with groove connecting screw rod and pressure sensor and the outer cone sleeve pipe and closely be not prone to the slit, the staff only can judge poor reliability and complex structure, the problem that cost is high to contiguity by experience.
Technical solution of the present utility model is:
This outer cone insulator cap with groove connecting screw rod and pressure sensor 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 clamping Anti-extrusion groove; Described groove is arranged on distance and chases after insulator cap openend 10 ~ 20mm place outward; Be provided with pressure sensor on the insulating barrier inwall, be provided with on the insulating barrier outer wall for the display unit that shows insulating barrier inwall pressure, pressure sensor is connected with display unit; 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;
Width 5 ~ the 10mm of above-mentioned groove, the degree of depth is 3 ~ 5mm.
Above-mentioned insulating barrier arranged outside has screen.
Above-mentioned pressure sensor is connected by wire with display unit, is provided with the wire guide that passes through for wire on the insulating barrier, and wire is by two openend insulated enclosures of insulating barrier wire guide behind the wire guide.
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 groove connecting screw rod and pressure sensor 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, this outer cone insulator cap with groove connecting screw rod and pressure sensor has increased connecting screw rod, pressure sensor and display unit, is convenient to the staff scene and intuitively connection status is judged, has further improved bonding strength.

The accompanying drawing detail is as follows:
The 1-groove; The 2-insulating barrier; 3-ear seat; The 4-screw rod; The 5-display unit; The 6-wire guide
The 7-pressure sensor; The 8-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 groove connecting screw rod and pressure sensor comprises the housing 8 that is fixedly installed in the insulating barrier 2, insulating barrier 2 is processed into integral piece with housing 8 sulfurations, be provided with the outer cone sleeve pipe suitablely on insulating barrier 2 inwalls, be used for clamping Anti-extrusion groove 1; Groove 1 is arranged on distance and chases after insulator cap openend 10 ~ 20mm place outward, the width 5 ~ 10mm of groove 1, and the degree of depth is 3 ~ 5mm.Be provided with pressure sensor 7 on insulating barrier 2 inwalls, be provided with on insulating barrier 2 outer walls for the display unit 5 that shows insulating barrier 2 inwall pressures, pressure sensor 7 is connected with display unit 5; Pressure sensor 7 and display unit 5 are connected by wire, are provided with the wire guide 6 that passes through for wire on the insulating barrier, and wire is by 6 two openend insulated enclosures of wire guide 6 rear insulating barrier 2 wire guides.
In order further to improve bonding strength, the utility model has increased connecting screw rod 4 these special devices, 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 3 in insulating barrier 2 outsides, screw rod 4 other ends are 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 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 boss, in the installation process, only need the outer cone sleeve pipe is directly pushed outer chasing after in the insulator cap, and make boss snap in groove 1 interior getting final product, again screw rod 4 is connected on the ear seat 3, and regulates by screw thread, further improve bonding strength, prevent from coming off.The numerical value that obtains by the pressure sensor 7 that demonstrates on the observation display unit 5 after the installation, staff's control value determines whether device is qualified.
Boss should adopt electro-insulating rubber or other that flexible insulation material is arranged, and the bonding strength after so both having guaranteed to install is not prone to the slit, so that be convenient to extract when the needs such as maintenance or replacing take out the outer cone sleeve pipe yet.
