Abstract

The utility model relates to a crimping-type equipment wire clamp, comprising a wiring tube and a wiring board. A tail end of the wiring tube horizontally extends to form the wiring board. The circular end surface of a head end of the wiring tube has at least two arc plates which extend in axial directions and are outwardly dispersed in radial directions. The arc plates surround to form a zone having a bell mouth. According to the crimping-type equipment wire clamp, the bell mouth is arranged at the head end of the wiring tube, and thus a requirement of accessing a lead in the normal operation is satisfied, and more importantly, when the diameter of the lead is large and a corresponding equipment wire clamp is deficient, the lead can still be directly arranged at the bell mouth. Then the arc plates can be clamped tightly to achieve effective fastening connection between the wiring tube and the lead, and thus the crimping-type equipment wire clamp is widened in applicable range. In addition, as antiskid teeth are arranged on the inner cambered surfaces of the arc plates, when the arc plates are clamped, effective parts of the antiskid teeth can be embedded in the lead or at least play a role in effectively extruding the lead, and thus the connection between the equipment wire clamp and the lead is enabled to be reliable.

Description

A kind of crimping equipment clamp

Technical field

The utility model relates to a kind of contact gold utensil, relates in particular to a kind of crimping equipment clamp.

Background technology

this device clamp is mainly used in substation busbars downlead and electric equipment (as transformer, circuit breaker, isolating switch, instrument transformer) binding post connects, and the continuing of wall bushing and bus, in prior art, crimping equipment clamp comprises all that generally wire barrel and the terminal block of by the wire barrel rear, being postponed form, because the internal diameter of wire barrel is single, therefore, need to select corresponding device clamp to meet being fastenedly connected between wire barrel and wire for the difference of wire diameter, make under special circumstances (when for example electric power rescues, lack corresponding device clamp), the applicability of this device clamp is too single, and then affect the operation process.

Summary of the invention

The purpose of this utility model is to overcome the defect of prior art, and a kind of simple in structure, reliable and stable, crimping equipment clamp that applicability is wide is provided.

For achieving the above object, the utility model adopts a kind of crimping equipment clamp, comprise a wire barrel and the terminal block of from this wire barrel end, laterally postponing, have at least two arcs that axially extend, also radially outward scatter on the annular end face of wherein said wire barrel head end, the interval that described arc surrounds into forms horn mouth.

Concrete, be provided with at least one anti-slop serrations in circumferential direction on the intrados of described arc.

By the technique scheme improvements over the prior art, due to after the head end at wire barrel arranges horn mouth, not only met the requirement of access wire in the normal operation, the more important thing is, bigger than normal and while lacking corresponding device clamp at wire diameter, also can directly wire be inserted the horn mouth position, then arc is clamped, make wire barrel and wire form effectively and be fastenedly connected, enlarged the scope of application of device clamp; In addition, owing to being provided with anti-slop serrations on the intrados of arc, therefore, when clamping arc, can make this anti-slop serrations effectively be partially submerged into wire or at least wire be formed effective squeezing action, and make this device clamp more reliable with being connected of wire.

Embodiment

As shown in Figure 1 and Figure 2, specific embodiment of the utility model is a kind of crimping equipment clamp, in Fig. 1 obviously as can be known, the crimping equipment clamp of the present embodiment comprises a wire barrel 1 and the terminal block 2 of from this wire barrel 1 end, laterally postponing, have at least two arcs 3 that axially extend, also radially outward scatter on the annular end face of wherein said wire barrel 1 head end, in the present embodiment, in conjunction with Fig. 2 obviously as can be known, the quantity of described arc 3 is preferably four, and the interval that described arc 3 surrounds into forms horn mouth 4.

Show in the present embodiment, have three anti-slop serrations 30 in circumferential direction on the intrados of described arc 3 in Fig. 1, more clear for accompanying drawing is represented, the anti-slop serrations 30 in the present embodiment is used dotted line as concise and to the point sign in Fig. 2.

Above demonstration and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and claim and the equivalent thereof appended by the claimed scope of the utility model define.

Claims

1. crimping equipment clamp, comprise a wire barrel and the terminal block of from this wire barrel end, laterally postponing, it is characterized in that: have at least two arcs that axially extend, also radially outward scatter on the annular end face of described wire barrel head end, the interval that described arc surrounds into forms horn mouth.

2. a kind of crimping equipment clamp according to claim 1, is characterized in that: be provided with at least one anti-slop serrations in circumferential direction on the intrados of described arc.
