Abstract
The utility model relate to a novel parallel groove clamp, comprising a punch holder (1) and a die holder (3), which are connected by a fastener. The parallel groove clamp is characterized in that clamp channels between the punch holder (1) and the die holder (3) are equipped with metal covering pipes (2), so that the punch holder (1) and the die holder (3) clamp the leads through the metal covering pipes (2). Through trials, the parallel groove clamp provided by the utility model thoroughly solves the problem of heating of a connection part of a distribution line drainage wire and a main line, and ensures safe and stable operation of the distribution line.
Description
Technical field
The utility model relates to a kind of novel parallel groove clamp.
Background technology
The safe handling of parallel groove clamp is directly connected to the reliability of city power distribution circuit, at present distribution line drainage thread and most of parallel groove clamp that adopts of being connected of main line.Find have scaling loss, disconnected burst fault to occur more through operation in a few years, in summer during large load operation, because the parallel groove clamp heating disconnects wire clamp and terminal scaling loss, cause line tripping and have a power failure, reduction circuit operational reliability.
Be example with JB-3 type parallel groove clamp, the improper use of parallel groove clamp causes the contact heating easily, and supply line's reliability is reduced, and is in particular in three aspects:
(1) JB-3 type parallel groove clamp is applicable to from 120-150mm from design concept
2All leads in the scope of cross section, the scope of application is extensive, brought a lot of convenience for aspects such as engineering construction, material selection and buying, but in actual moving process, workmen's parallel groove clamp commonly used is connected gold utensil as backbone with drainage thread, and remedies the bigger deficiency of line footpath difference with aluminium armor tape.The rated current of backbone of flowing through but will be far longer than the rated current of drainage thread, when backbone during at large load operation, connecting the JB-3 type parallel groove clamp of terminal and the contact area of lead does not but change, only maintain and satisfy the level that low current passes through, and the electric current that increases suddenly is during through this type of parallel groove clamp, because excessively the corresponding increasing of resistance causes heating, causes line fault to take place frequently.
(2) in the wire clamp heating, the conducting line segment that is connected is scaling loss, distortion at high temperature, has increased the slit between wire clamp and lead again, increases excessive resistance, causes wire clamp and lead to generate heat again, and vicious circle finally burns out broken string and causes the accident.
(3) contact area of wire clamp and lead is little, lead all can not be included in the wire clamp, when construction or maintenance, if crimping is firmly excessive, causes the lead damage easily, the side damage wires that deflection does not stress.
The utility model content
The purpose of this utility model provides a kind of novel parallel groove clamp, can guarantee safety, the stable operation of distribution line with contact temperature control in the set point of temperature scope.
A kind of novel parallel groove clamp, comprise train wheel bridge and lower plate, connect with securing member between this train wheel bridge and the lower plate, its special feature is: wherein in the passageway between train wheel bridge and lower plate metal sleeve is installed all, thereby makes train wheel bridge and lower plate by this metal sleeve clamping lead.
Wherein on metal sleeve, have an elongated slot vertically, and the equal in length of the length of this elongated slot and metal sleeve.
Wherein on metal sleeve, have a short groove vertically, and the length of this weak point groove is 0.8-0.99 times of metal sleeve length.
Wherein metal sleeve adopts aluminium or copper material.
Wherein the thickness of metal sleeve is 1-6mm.
Through probationary certificate, adopt parallel groove clamp of the present utility model after, thoroughly solved the heating problem of distribution line drainage thread and main line connecting portion, guaranteed the safe and stable operation of distribution line.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is the structural representation of metal sleeve 2 in the utility model.
Embodiment
As shown in Figure 1, the utility model is a kind of novel parallel groove clamp, comprise train wheel bridge 1 and lower plate 3, connect with securing member between this train wheel bridge 1 and the lower plate 3, wherein in the passageway between train wheel bridge 1 and lower plate 3 metal sleeve 2 is installed, thereby makes train wheel bridge 1 and lower plate 3 by these metal sleeve 2 clamping leads (cable core).
As shown in Figure 1, 2, on metal sleeve 2, have an elongated slot 5 vertically, and the equal in length of the length of this elongated slot 5 and metal sleeve 2, being about to metal sleeve 2 runs through fully, have a short groove 4 in addition vertically on metal sleeve 2, and the length of this weak point groove 4 is 0.8-0.99 times of metal sleeve 2 length, namely metal sleeve 2 is not run through fully and is still had the junction existence, and metal sleeve 2 thickness are 1-6mm, specifically can adopt aluminium or copper material.
Using method of the present utility model is:
During use metal sleeve 2 is enclosed within on the lead, use train wheel bridge 1 and lower plate 3 clamping metal sleeve 2 and leads then, thereby tight a bolt again can make fully to contact between train wheel bridge 1, metal sleeve 2, lead and the lower plate 3 and reduce resistance, when tightening can rupture in the metal tube junction at usually short groove 4 places, whole metal tube is disconnected becomes two semicanals, can further increase contact area like this.
Claims (5)
1. novel parallel groove clamp, comprise train wheel bridge (1) and lower plate (3), connect with securing member between this train wheel bridge (1) and the lower plate (3), it is characterized in that: wherein in the passageway between train wheel bridge (1) and lower plate (3) metal sleeve (2) is installed all, thereby makes train wheel bridge (1) and lower plate (3) by this metal sleeve (2) clamping lead.
