Abstract

A clamp splice type porcelain wire clamp is characterized in that the porcelain wire clamp body comprises an upper clamp splice type porcelain block and a lower clamp splice type porcelain block in mutual press fit, wherein at least two wire crimping grooves are uniformly distributed on the upper surface of the lower porcelain block for fastening leads, a bolted connection hole is opened at the center of the upper surface of the lower porcelain block or between the two wire crimping grooves, a gasket groove is opened above the connection hole, an upper connection hole is opened on the upper porcelain block corresponding to and matched with the bolted connection hole on the lower porcelain block, and the upper porcelain block is fixedly connected with the lower porcelain block via a bolt and a nut connecting piece matched with the bolt. Compared with the prior art, the porcelain wire clamp provided in the utility model has the advantages of rapid wiring and installation, convenient maintenance, low labor consumption due to no need of banding and fixing wires, and convenience for both wire installation and wire repair; and is suitable for erecting and installing insulated house-service wires of 0.4KV and television and telephone wires.

Description

The fixture block formula porcelain cleat that stringing is used

(1), technical field

The utility model relates to a kind of equipment of the usefulness that installs electric wiring, particularly a kind of stringing fixture block formula porcelain cleat.

(2), technical background

For the wiring of commercial power family or electric consumption on lighting family stringing is one of the lineman of power supply station routine work; at present the linesman mainly contains porcelain vase (also claiming the butterfly bottle) at used stringing equipment on the electric pole or on the wall of user's building; stringing equipment such as cross-arm that the fixed installation porcelain vase is used or wall nail; the wall nail can directly be thrown in the wall; cross-arm can be fixing more firm with expansion bolt; the electrician is when stringing; if this moment, electric wire to be set up was terminal electric wire (referring to what electric wire was directly registered one's residence for user use); the electrician just with electric wire on the wire casing of porcelain vase around the volume one the circle or one the circle more than; also to use iron wire or aluminum steel that electric wire colligation on porcelain vase is firm in addition; if lead to be set up is nonterminal electric wire (referring to could to insert electricity consumer after electric wire needs to lay through a stringing at least again uses); (also can only enclose around volume one) used the metal wire colligation firm again after then the electrician just need only walk around electric wire the porcelain vase wire casing; above-mentioned stringing operation exists the stringing installation rate slow; electrician's complex operation; very hot if; dismounting electric wire inconvenience, and easily lose shortcoming such as lead.

(3), summary of the invention

The purpose of this utility model is the fixture block formula porcelain cleat used of a kind of stringing of design, and it is all very convenient to have an installing/dismounting electric wire, need not to fix with wiring, saves labor the advantage that stringing distribution service speed is fast.

For achieving the above object, the utility model has adopted following technical scheme; This fixture block formula porcelain cleat comprises the porcelain cleat body, the fixed-use bolt connector, it is characterized in that: described porcelain cleat body is by on the fixture block formula that can be laminated, lower glazed tile is formed, the upper surface of lower glazed tile (or line ball use) pressuring line groove of being evenly equipped with that at least two secure wires use wherein, offer bolt connecting hole between surface central authorities or two pressuring line grooves thereon, above connecting hole, offer spacer groove, described upper glazed tile central authorities also offer corresponding with the bolt connecting hole of lower glazed tile supporting on connecting hole, upper glazed tile can be fixedlyed connected with lower glazed tile by bolt and the screw connector that matches with it.

Technique scheme of the present utility model can also further be specially:

One, the spacer groove of being offered above the central connecting hole of described lower glazed tile can be designed to the shape of square or hex-shaped recess, also can be designed to rise the rectangular channel form structure of cross section of insulating effect.

Two, described bolt connection piece is to make the stud that the middle part has the pad piece, and the thickness of described pad piece should be less than the height of spacer groove, so that firm the clamping.Described pad piece can be to be designed to hexagon or square planform, so that nut screws firmly.

Three, described spacer groove also can be opened in the bottom of upper glazed tile central authorities connecting hole.

Four, in the bottom of described upper glazed tile and the bottom of lower glazed tile and the surface of pressuring line groove all be designed to rough surface (when firing, making the matsurface of diamond-shaped knurling shape), to increase the frictional force between each contact-making surface when mounted.

When using the utility model fixture block formula porcelain cleat to install electric wiring; can utilize the cross-arm or the wall nail of original fixedly porcelain vase to install; its operating process is as follows: the electrician is fixedly installed in cross-arm (the generally fixture made from angle bar) on the electric pole or is fixed on the building walls earlier and (can directly squeeze in the wall when using the wall nail; can be connected and fixed with setscrew when using cross-arm); utilizing bolt and nut that lower glazed tile is pre-fixed at cross-arm or wall nails on; the lead that needs are set up accurately places the pressuring line groove of lower glazed tile; with in the upper glazed tile pressing, screwed upper cap nut just again.Compared with the prior art, the utility model stringing installation rate is fast, easy to maintenance, because of need not the colligation securing electric lines, so very save labor, no matter be that installation or dismounting maintenance circuit are all very convenient, be applicable to the house lead in of insulated conductor and the setting up of service wire of 0.4KV, also be applicable to the installation of setting up of leads such as TV, phone.
