Description
Technical field
The utility model relates to a kind of mode of connection of testing routinely of electric system secondary specialty, and particularly relating to a kind of is the buckle-type connection plug of ring type terminal block for cable.
Background technology
Test wire connection plug is mainly used in electric system secondary specialty and tests routinely, and the connection plug often used in prior art has crocodile clip-type connection plug, needle-like connection plug, fork type connection plug.Crocodile clip-type connection plug utilizes the grip force of crocodile clip to be fixed on connection terminal screw, but due to screw cap less, contact area is little, and easily touch during wiring and come off, fastness is poor; Needle-like connection plug and fork type connection plug are fixed mainly through screw pressure, and fastness is strong, but also need piezoelectricity cable due to screw, not easily mount and dismount, if connection terminal has two wiring, more should not adopt.
Need multiple personnel to coordinate due to during test, change setting up time during test long, just cause multiple personnel to wait for, affect work efficiency.If secondly in process of the test, wiring is insecure, causes connection plug to come off, makes test be forced to stop, also need to redo.The connection plug of prior art is unfavorable for the assurance of the efficiency raising of secondary specialty testing crew wiring and the fastness of wiring causing great puzzlement to experiment work.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, and provide a kind of buckle-type connection plug, the utility model structure is simple, have easy to use, fastness is strong, and easily assembling function, can improve fastness and the stability of testing crew wiring efficiency and experimental wiring.
For achieving the above object, the utility model realizes by the following technical solutions:
A kind of buckle-type connection plug, comprise connection plug, buckle-type screw, described connection plug comprises insulation hard plastic cover, buckle spring, metal guide fulgurite, described metal guide fulgurite is fixed on insulation hard plastic cover inwall, be fixed with buckle spring in one end of metallic conduction inside pipe wall, described buckle-type screw is screwed onto on trial voltage current terminal; During wiring, described connection plug is with one end of buckle spring and the grafting of buckle-type screw, and buckle-type screw-clamped is fixed by buckle spring, the other end grafting wire of connection plug.
Described buckle-type screw comprises buckle head, screw rod, and buckle head is fixed on one end of screw rod, buckle head is provided with one week groove.
Compared with prior art, the beneficial effects of the utility model are:
1) structure is simple, and cost is low, and be convenient to installation and removal, structural strength is good.
2) improve testing crew wiring efficiency and stability, for safety in production provides effective convenience.

Embodiment
Below in conjunction with Figure of description, the utility model is described in detail, but it should be noted that enforcement of the present utility model is not limited to following embodiment.
As shown in Figure 1-2, a kind of buckle-type connection plug, comprise connection plug, buckle-type screw 4, described connection plug comprises insulation hard plastic cover 1, buckle spring 2, metal guide fulgurite 3, described metal guide fulgurite 3 is fixed on insulation hard plastic and overlaps on 1 inwall, be fixed with buckle spring 2 in one end of metal guide fulgurite 3 inwall, described buckle-type screw 4 is screwed onto on trial voltage current terminal; During wiring, described connection plug is with one end of buckle spring 2 and buckle-type screw 4 grafting, and buckle-type screw 4 is fixedly clamped by buckle spring 2, the other end grafting wire 5 of connection plug.
One end that described buckle-type screw 4 comprises buckle head 4-1, screw rod 4-2, buckle head 4-1 are fixed on screw rod 4-2, buckle head 4-1 is provided with one week groove 4-3.
Buckle spring 2 and buckle-type screw 4 are the good metal material of electric conductivity.
A using method for buckle-type connection plug, comprises the following steps:
1), when electric system secondary specialty is tested routinely, the terminal screw on electric current and voltage terminal is disassembled;
2) the screw rod 4-2 of buckle-type screw 4 is screwed in the threaded hole on electric current and voltage terminal, is originally operating as disposable operation, permanent use;
3) connector lug of test lead 5 is inserted from connection plug without buckle spring terminal, again by the other end sleeve of connection plug on the buckle head 4-1 of buckle-type screw 4, buckle spring 2 is stuck in the groove 4-3 of buckle head 4-1, buckle head 4-1 is fixedly clamped by the opening and closing forces that buckle spring 2 produces temporarily, and wiring completes;
4) after off-test, directly pulled up from buckle-type screw 4 by connection plug, buckle-type screw 4 is stayed on terminal to treat that next time uses.
A kind of buckle-type connection plug of the utility model is made up of connection plug and buckle-type screw 4 two parts, connection plug is the cylindrical tubular shape of inner conductive, exterior insulation, inner one end is provided with buckle spring 2, the buckle head 4-1 at buckle-type screw 4 top is provided with groove 4-3, and the mode that connection plug is similar to snap-fastener with buckle-type screw 4 coordinates.
The other end of connection plug is conventional test line jack, and test lead 5 only needs to insert in the cylindrical hole of connection plug.The jack of buckle-type connection plug and conventional test line electric conductivity are good and firmly, buckle spring 2 in connection plug coordinates degree of tightness appropriateness with buckle-type screw 4, can ensure that wiring firmly overcomes the requirement of slight touching and test lead gravity, can ensure again to use moderate external force can easy removal, damage can not be caused to buckle-type screw 4 and terminal block.Simultaneously, electric conductivity that can also be good between warranty test wire 5, connection plug, buckle-type screw 4 and terminal block, the insulation hard plastic cover 1 of connection plug outside is convenient to worker safety's operation, mainly prevention work personnel forget close test export and reconfiguration line time cause the personal injury of error shock, play the effect of auxiliary security protection.
The total length appropriateness of connection plug, meet the protrusion metallic plug length sum of buckle-type screw 4 length and test lead 5, too short, test lead can not coordinate completely with connection plug, easily comes off; Long then due to lever principle, it is larger that the grip of buckle-type connection plug needs to overcome test lead 5 gravity.
The utility model is applicable to mode of connection when secondary specialty is tested routinely, because second trial carries out input analog amount mainly for electric current and voltage terminal, only need screw original on electric current and voltage terminal to be replaced by buckle-type screw 4 can with connection plug with the use of, later buckle-type screw 4 just can be stayed in terminal block, permanent use.
