Description
Technical field
The utility model relates to the anti-dust water-proof device of electric equipment cable outlet mouth, refers to particularly the replaceable cable locking head of a kind of split-type.
Background technology
In the plant equipment field, the dustproof and waterproof of electric equipment cable outlet mouth must rely on the cable locking head to realize, when the normal cable locking head is installed, need cable before the access electric equipment, from the cable locking head, to pass, again the cable locking head is fixed on the cable outlet hole, then wiring school line, this that is to say, for the electric equipment after finishing at cable connection, if the requirement for dustproof and waterproof, need to consider to install or change locking head additional at cable outlet mouth place, that just must remove original cable, rewiring school line behind the installing cables locking head; If this cable power cable just can carry out after also must having a power failure, otherwise causes the accident easily; If this cable multicore cable also must each core of mark, otherwise the easy wrong of wiring when recovering; If the online equipment that this equipment is important, if do not take special measure, that just can carry out in the time of also must waiting until stop production to overhaul, and therefore needs are a kind of can be in the situation that need not remove the inlet wire cable, the cable locking head of installing.
Summary of the invention
The purpose of this utility model is exactly to overcome the defective that existing cable locking head device exists, provide a kind of can do not remove install in the cable situation with change the replaceable cable locking head of split-type.
For achieving the above object, the replaceable cable locking head of split-type that the utility model is designed, comprise the chuck screw and with the chuck nut of its threaded engagement, described chuck screw upper end with hook, lower end with the fastening clip for cable head, be provided with the cavity that current supply cable passes in the described chuck screw, its special character is: described chuck screw is to cut two symmetrical valve structures open, also for cutting two symmetrical valve structures open, two lobes of described chuck nut are fixed as one by connecting bolt described chuck nut.
Further, the cutting plane of described chuck screw two lobe the first half and split are 3 ~ 5 ° of angles, and the cutting plane of described chuck screw two lobe the latter halfs overlaps with split.Like this, can be convenient to during installation make the hook of chuck screw upper end to enter the cable box entrance hole.
Further, be respectively equipped be used to the groove that is located by connecting and raised line on the cutting plane of described chuck screw two lobes, also be respectively equipped be used to the groove that is located by connecting and raised line on the cutting plane of described chuck nut two lobes.Like this, can so that the centering of chuck nut and chuck screw two lobes is fixed, be conducive to tightening smoothly of chuck nut and chuck screw.
Further, the tapered structure of fastening clip for cable head of described chuck screw lower end, the latter half of the inner chamber of described chuck nut two lobes is the cone-shaped cavity structure that matches with the fastening clip for cable head.Like this, when chuck nut and chuck screw are progressively tightened, can make the clamping with the subjacent cable fixed chuck of opening of chuck screw top hook.
Further, be provided with the annular groove that holds adhesive waterproof tape in the cavity of described chuck screw.Like this, adhesive waterproof tape firmly can be clamped on the cable, guarantee the water proof and dust proof effect.
The utility model has the advantage of: the cable that the replaceable cable locking head of designed split-type can be applicable to outdoor cable dish bin or equipment cable outlet is fixed and is sealed, more conventional locking head, this structure can be dismantled and change at any time, can after finishing, install again cable connection, can in the situation that does not need to take out stitches and have a power failure, increase or change locking head, equipment in service is not produced any impact, maintenance and installation are very simple, and the dustproof and waterproof sealing is all right, and it is particularly efficient and convenient in engineering project the cable outlet mouth to be increased the cable locking head especially.This locking head strong adaptability can be produced in batches, and is with low cost.
Description of drawings
Fig. 1 is the stereo decomposing structural representation of the replaceable cable locking head of a kind of split-type.
Fig. 2 is the mounting means schematic diagram of the replaceable cable locking head of split-type shown in Figure 1.
Each parts label is as follows among the figure: chuck screw 1, chuck nut 2, hook 3, fastening clip for cable head 4, connecting bolt 5, annular groove 6, adhesive waterproof tape 7.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
The replaceable cable locking head of split-type shown in the figure, comprise chuck screw 1 and with the chuck nut 2 of its threaded engagement, chuck screw 1 upper end with hook 3, lower end with fastening clip for cable head 4, be provided with the cavity that current supply cable passes in the chuck screw 1, chuck screw 1 is for cutting two symmetrical valve structures open, also for cutting two symmetrical valve structures open, two lobes of chuck nut 2 are fixed as one by connecting bolt 5 chuck nut 2.The cutting plane of 1 liang of lobe the first half of chuck screw and split are 3.5 ° of angles, and the cutting plane of 1 liang of lobe the latter half of chuck screw overlaps with split.The fastening clip for cable head 4 tapered structures of chuck screw 1 lower end, the latter half of the inner chamber of 2 liang of lobes of chuck nut is the cone-shaped cavity structure that matches with fastening clip for cable head 4.Be respectively equipped be used to the groove that is located by connecting and raised line on the cutting plane of 1 liang of lobe of chuck screw, also be respectively equipped be used to the groove that is located by connecting and raised line on the cutting plane of 2 liang of lobes of chuck nut.Also be provided with the annular groove 6 that holds adhesive waterproof tape 7 in the cavity of chuck screw 1.
