Abstract

The utility model discloses a wrapped connection wire clamp with electrical leads free of mechanical connection. The wire clamp comprises a wire clamp body and a fastener assembly. The wire clamp body is a long groove body with a U-shaped cross section. The fastener assembly is arranged transversely through the opening of the U shape of the wire clamp body. The cross section of the lower portion of the U-shaped wire clamp body is in an epsilon shape. The epsilon-shaped internal wall of the wire clamp is formed by intersected two 180-270 DEG semicircle wall bodies in the lower portion of the wire clamp body, and the highest point of the protruded body in the intersected position in middle of the two semicircle wall bodies of the internal wall of the wire clamp body is located above the upper portion of the connection line of two centers of the two semicircles. The wire clamp is an electrical lead connection clamp with convenient use and safe and reliable connection.

Description

What a kind of electrical lead did not stress and connects wraps up in and connects formula wire clamp

Technical field

The utility model relates to a kind of electrical lead jockey, it is a kind of wire clamp being formed by groove type wire clamp body and fastener combination, it is applicable to the connection that do not stress of electrical lead, the strain insulator that is specially adapted to transmission line, distribution line, low-voltage circuit is crossed and is drawn that wire jumper connects and " T " connects, and electric substation, factory's electricity distribution power wire connect.

Background technology

Now, the connection that do not stress of the electrical lead of electric line and electric substation, factory's distribution, what generally use is parallel groove clamp and "T"-shaped wire clamp, these wire clamp contact resistances are large, galvanic corrosion wound is fast, burn, broken string accident occur again and again, being the weak link of electrical network, is also the major hidden danger of electrical network.Connect formula wire clamp although have one to wrap up at present, in the middle part of " ω " shape due to this wire clamp intracoelomic cavity, raised body is lower connects poor reliability to wrapping up in of wire.

Summary of the invention

The purpose of this utility model is to overcome prior art deficiency, provide a kind of to wrapping up in of wire connect reliably, good connecting effect, wire connect the easy electrical lead of operation the wrapping up in of connecting that do not stress and connect formula wire clamp.

The purpose of this utility model can realize by following technical scheme:

What a kind of electrical lead did not stress and connects wraps up in and connects formula wire clamp, formed by wire clamp body and fastener combination, wire clamp body is the microscler cell body that cross section is " U " font, the fastener combination that is laterally coated with suitable for reading of " U " font of online clamp, the cross section of " U " font wire clamp body of wire clamp body bottom is " ω " font, " ω " font of wire clamp body inwall is that the semicircular arc wall body of two 180-270 degree of wire clamp body lower inner wall intersects formation, the peak of the raised body of the intersection, two semicircular arc wall body middle parts of its wire clamp body inwall is on the top of the line in the center of circle of two semi arches, raised body described herein refers to the raised body at " ω " font middle part of wire clamp body bottom, the height of this raised body is generally greater than the radius of the circular arc of two semicircular arc wall bodies herein, sometimes also can be equal to or less than as required the radius of circular arc.

The purpose of this utility model can also realize by following technical scheme:

The pad of fastener combination described in the utility model between nut and wire clamp body is rectangle pad, the bolt of fastener combination is T-slot bolt, T-slot bolt is for be provided with the T-shaped body that the rectangular plate body vertical with screw rod forms in the bottom of screw rod, and 1/2nd centers of the bolt mounting hole that installs fastener combination that are all greater than wire clamp body with 1/2nd of the length L of rectangle pad of plate body length L are to " ω " font wire clamp body of wire clamp external body and the distance H of the vertical wire clamp body intersection at the place suitable for reading of " U " font of wire clamp body.

All there is chamfering at four angles of rectangle pad described in the utility model and plate body, and rectangle pad and plate body after chamfering are all eight angle type.

The advantage that the utility model compared with prior art has is: be difficult for producing galvanic corrosion, wrap up in to connect and be connected firmly, contact resistance is less than, connect safe and reliable, cost is low, installing/dismounting operation is convenient, particularly raised body increase wrap up in connect in succession more firm, adopt T-slot bolt under the prerequisite that does not need set bolt, can screw easily nut.

Embodiment

Shown in Fig. 1-2: what a kind of electrical lead did not stress and connects wraps up in and connect formula wire clamp, formed by wire clamp body 1 and fastener combination 2, wire clamp body 1 is the microscler cell body of " U " font for cross section, the fastener combination 2 that is laterally coated with suitable for reading of " U " font of online clamp 1, the cross section of " U " font wire clamp body of wire clamp body 1 bottom is " ω " font, and " ω " font of wire clamp body inwall is that the semicircular arc wall body of two 180-270 degree of wire clamp body 1 lower inner wall intersects formation.The peak of the raised body of the intersection, two semicircular arc wall body middle parts of wire clamp body 1 inwall is on the top of the line in the center of circle of two semi arches.The pad of described fastener combination 2 between nut 3 and wire clamp body 1 is rectangle pad, the bolt of fastener combination 2 is T-slot bolt, the T-shaped body that T-slot bolt is vertical with screw rod is rectangular plate body, and 1/2nd centers of the bolt mounting hole that installs fastener combination 2 that are all greater than wire clamp body 1 with 1/2nd of the length L of rectangle pad of plate body length L are to " ω " font wire clamp body of wire clamp body 1 outside and the distance H of the suitable for reading vertical wire clamp body intersection of " U " font of wire clamp body 1.All there is chamfering at four angles of described rectangle pad and plate body, and rectangle pad and plate body after chamfering are all eight angle type.
