Abstract
The utility model discloses a solve the problem that prior art existed, find a fastener with electrified lead wire that inserts of limit function, effectively reduce the gap with the wire contact face. Including clamp, screw rod, lead wire closing device, the clamp is used for being cusp male and female face structure with wire contact's position, the screw rod is used for being cusp male and female face structure with wire contact's position. Through implementing the utility model discloses can gain following useful technological effect: reduce with the gap of wire contact face, can effectively avoid local burble and the emergence that reduces defect and trouble, improve the sustainability of confession power consumption.
Description
Technical field
The utility model relates to power domain, is specifically related to the wire clamp of the charged access lead-in wire of a kind of limited location function.
Background technology
The charged wire clamp disconnecting lead-in wire application of 10kV distribution line, use a kind of charged assembly and disassembling type wire clamp of YZ type, when accessing lead-in wire, after being fixed on the side of wire clamp afterbody by needing the lead-in wire of access, its wire clamp (band fixes the lead-in wire of one end) act is suspended on wire with insulating bar by live line working personnel to the position of live wire, hang (card) lead screw to wire clamp afterbody with insulating bar again, rotate insulating bar and tightened, namely go between charged access.
This kind of wire clamp one is wire clamp and wire is point cantact, and its reliable (closely) degree, has gap, its contact does not reach predetermined degree, and its current capacity is subject to certain restrictions, when especially having big current to pass through, the defect that easy generation is overheated, of a specified duration causes fault.Two be the screw rod of this wire clamp after tightening, with parallel wire in vertical state, circuit is in long-term operation, the swing of its screw rod by wind, there will be loosening defect, and current-carrying not only can be caused limited, more easily cause the overheated of loosening property, the of a specified duration fault that there will be broken string.
Utility model content
The purpose of this utility model is to solve the problem existing for prior art, finds a kind of wire clamp with the charged access lead-in wire of limit function, effectively reduces the gap with conductor contact surface.
In order to realize described object, a kind of wire clamp with the charged access lead-in wire of limit function, comprise clamp, screw rod, device for pressing wire lead, it is dentation male and female face structure that described clamp is used for the position of conductive contact, and it is dentation male and female face structure that described screw rod is used for the position of conductive contact.
Preferably, described device for pressing wire lead is used for the position of wire contacts is dentation male and female face structure.
Preferably, described screw rod is provided with for spacing groove, and described clamp is provided with for the spring catch with groove fit.
Preferably, described device for pressing wire lead comprises arc pressuring plate and fixed screw, and described arc pressuring plate is connected with clamp by fixed screw, and the position that described arc pressuring plate is corresponding with pressing plate is provided with arc-shaped recess portion.
Preferably, described device for pressing wire lead comprises arc pressuring plate and fixed screw, and described arc pressuring plate is connected with clamp by fixed screw.
Following Advantageous Effects can be obtained by implementing the utility model: reduce the gap with conductor contact surface, local effectively can be avoided to produce eddy current and reduce the generation of defect pipelines, improving the sustainability for electricity consumption.Spring catch automatic spring, to screw limiting, prevents screw rod from loosening because external force is reversing.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is the partial enlarged drawing at A place in Fig. 2.
Embodiment
For the ease of the understanding of those skilled in the art, below in conjunction with specific embodiment, the utility model is further described:
As depicted in figs. 1 and 2, a kind of wire clamp with the charged access lead-in wire of limit function, comprise clamp 1, screw rod 2, device for pressing wire lead 3, clamp 1 is for the dentation male and female face structure of position 11 (contact-making surface) in fragmentary slightly point with conductive contact, screw rod 2 is for the dentation male and female face structure of position 21 (contact-making surface) in fragmentary slightly point with conductive contact, device for pressing wire lead 3 is for the dentation male and female face structure of position 31 (contact-making surface) in fragmentary slightly point with wire contacts, screw rod 2 is provided with for spacing groove 21, clamp 1 is provided with the spring catch 12 for coordinating with groove 21, the ejection length of spring catch 12 is 1/2nd of screw rod 2 diameter, device for pressing wire lead 3 comprises arc pressuring plate 32 and fixed screw 33, arc pressuring plate 32 is connected with clamp 1 by fixed screw 33, the position that clamp 1 is corresponding with arc pressuring plate 32 is provided with arc-shaped recess portion 13, arc pressuring plate 32 is that device for pressing wire lead 3 is for the position 31 (contact-making surface) with wire contacts towards the face in arc-shaped recess portion 13 and arc-shaped recess portion 13 towards the face of arc pressuring plate 32, described screw rod 2 lower end is provided with the supporting rotating shaft of action bars 22.
The present invention manufactures the dentation male and female face (height of its each tooth is 2mm) in fragmentary slightly point leading, on wire contacts face, make its contact is led (drawing) line carry out fastening after, forming surface contacts, eliminate or reduce the gap between the per share and stock of wire, ensureing that its contact-making surface is large and reliable.On the screw rod 2 of online folder secure wires, by gauge wire outside dimension, a groove 21 is designed according to different conductor diameter dimension (i.e. fastening rear position) at its facade, separately manufacture a spring catch 12 in screw side (wire clamp bottom) by groove 21 shape and size, namely after groove 21 is completely corresponding with spring catch 12, spring catch 12 automatic spring is spacing to screw rod 2, prevents its screw rod 2 from loosening because external force is reversing.Spring catch 12 comprises spring and pin, and the length that pin ejects is 1/2nd of screw rod 2 diameter, and namely have when needing to remove its lead-in wire, when rotating its screw rod 2, pin is return voluntarily, does not affect the use repeatly of its wire clamp.
Following Advantageous Effects can be obtained: this wire clamp mates according to the standard model leading (drawing) line by implementing the utility model, at the wire clamp that its contact and fastening reliability use than before, reduce the gap with conductor contact surface, local effectively can be avoided to produce eddy current and reduce the generation of defect pipelines, improving the sustainability for electricity consumption.
The foregoing is only specific embodiment of the utility model, but technical characteristic of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and the change done or modification are all encompassed among the scope of the claims of the present utility model.
