CN204271291U - The penetrating cable clamp of a kind of contact - Google Patents

Abstract

The utility model discloses the penetrating cable clamp of a kind of contact, comprises upper clamp, lower clamp, it is characterized in that: described upper clamp and lower clamp are bolted; Described upper clamp, lower clamp corresponding section arrange groove; Described upper clamp arranges hold-down bolt, and described hold-down bolt is threaded with upper clamp; Described hold-down bolt lower end abuts with puncture seat; Described conehead quantity is 3, is respectively the limit conehead on both sides and the positive conehead in centre position; The height of described limit conehead is higher than positive conehead; Described limit conehead is obliquely installed with puncture seat.Principle of the present utility model and advantage are: due to the aspect ratio positive cone head height of limit conehead, so, first the limit conehead of both sides punctures insulating barrier, along with screwing of hold-down bolt, because limit conehead is obliquely installed, therefore it must tilt to both sides, like this, the contact of limit conehead and electric wire just becomes face and contacts, after hold-down bolt screws further, positive conehead and electric wire point cantact, two limit coneheads then expand contact area further.

Description

The penetrating cable clamp of a kind of contact

Technical field

The utility model relates to field of electrical equipment, is a kind of gold utensil specifically, is more specifically a kind of penetrating cable clamp.

Background technology

Penetrating cable clamp is widely used in power equipment, and existing penetrating cable clamp is all generally adopt the pressure of bolt, conehead is punctured after insulating barrier with line contacts; After conehead thrusts, the contact of conehead and electric wire is generally point cantact, and its drawback is because contact area is too small, adds the oxidation etc. of metal, easily comes in contact bad consequence at contact point, brings the damage of power equipment.Chinese Patent Application No. 201220026879.3 discloses a kind of spacing-type penetrating cable clamp, " it comprises the wire clamp part by the fastening upper wire clamp of clamping screw and the holder that rolls off the production line; the screw of upper wire clamp coordinates with puncture bolt, and the puncture conehead around puncture bolt is provided with annular stop platform." this patent solves the control problem that conehead thrusts the degree of depth, but do not solve " point cantact " problem.

Utility model content

For solving the problems of the technologies described above, the purpose of this utility model is to provide the penetrating cable clamp of a kind of contact, and concrete technical scheme is as follows:

Contact a penetrating cable clamp, comprise upper clamp, lower clamp, described upper clamp and lower clamp are bolted; Described upper clamp, lower clamp corresponding section arrange groove; Described upper clamp arranges hold-down bolt, and described hold-down bolt is threaded with upper clamp; Described hold-down bolt lower end abuts with puncture seat; Described puncture seat arranges multiple conehead.

Described conehead quantity is 3, is respectively the limit conehead on both sides and the positive conehead in centre position; The height of described limit conehead is higher than positive conehead; Described limit conehead is obliquely installed with puncture seat.

Principle of the present utility model and advantage are: due to the aspect ratio positive cone head height of limit conehead, so, first the limit conehead of both sides punctures insulating barrier, along with screwing of hold-down bolt, because limit conehead is obliquely installed, therefore it must tilt to both sides, like this, the contact of limit conehead and electric wire just becomes face and contacts, after hold-down bolt screws further, positive conehead and electric wire point cantact, two limit coneheads then expand contact area further.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is puncture seat and conehead structural representation.

Embodiment

Illustrate the utility model below in conjunction with accompanying drawing, as shown in Figure 1 and Figure 2, the utility model comprises upper clamp 1, lower clamp 2, and described upper clamp 1 is connected by bolt 3 with lower clamp 2; Described upper clamp 1, lower clamp 2 corresponding section arrange groove 6; Described upper clamp 1 arranges hold-down bolt 4, and described hold-down bolt 4 is threaded with upper clamp 1; Described hold-down bolt 4 lower end abuts with puncture seat 5; Described puncture seat 5 arranges multiple conehead.

The conehead quantity of the present embodiment is 3, is respectively the limit conehead 52 on both sides and the positive conehead 51 in centre position; The height h2 of described limit conehead 52 is higher than the height h1 of positive conehead; Described limit conehead 52 is obliquely installed with puncture seat 5, and namely in Fig. 2, the tap web line of conehead is less than 90 degree with the angle a of puncture seat.

Conehead material can adopt the good metal of ductility, to prevent conehead fracture of root, also conehead root shape can be arranged to arc transition, concentrates to prevent stress.

Conehead quantity can change according to designing requirement.
