Technical field
The present invention relates to a kind of mode of connection that the secondary profession of electric system is routinely tested, more particularly to one kind is for electricity
Cable is the buckle-type connection plug and application method of ring type terminal block.
Background technology
Test wire connection plug, which is mainly used for the secondary profession of electric system, routinely to be tested, and is commonly used in the prior art
Connection plug has crocodile clip-type connection plug, needle-like connection plug, fork type connection plug.Crocodile clip-type connection plug utilizes crocodile
The grip force of fish folder is fixed on connecting terminal screw, but since cap nut is smaller, contact area is small, and it is de- that when wiring is easy touching
It falls, fastness is poor；Needle-like connection plug and fork type connection plug are mainly fixed by screw pressure, and fastness is strong, but
It since screw also needs piezoelectricity cable, is not easy to mount and dismount, should not more be used if connecting terminal has two piece-root grafting lines.
Due to needing multiple personnel to coordinate when experiment, it is long that when experiment, replaces setting up time, results in multiple personnel and waits for, shadow
Ring working efficiency.If during secondly testing, wiring is insecure, and connection plug is caused to fall off so that experiment is forced to stop, and also needs
It redoes.The connection plug of the prior art is unfavorable for the efficiency raising of secondary professional testing crew wiring and the jail of wiring
The assurance of solidity causes greatly to perplex to experiment work.
Invention content
The purpose of the present invention is overcoming the deficiencies of the prior art and provide a kind of buckle-type connection plug and application method, this
Inventive structure is simple, have it is easy to use, fastness is strong, and easily assembling function can improve testing crew wiring efficiency and reality
Test the fastness and stability of wiring.
To achieve the above object, the present invention is realized using following technical scheme：
A kind of buckle-type connection plug, including connection plug, buckle-type screw, the connection plug include insulation hard plastic
Set, buckle spring, metallic conduction pipe, the metallic conduction pipe is fixed on insulation hard plastic set inner wall, in metallic conduction inside pipe wall
One end be fixed with buckle spring, the buckle-type screw is screwed onto on test voltage current terminal；When wiring, the wiring is inserted
Headband has one end and the buckle-type screw grafting of buckle spring, buckle spring to fix buckle-type screw-clamped, connection plug
Other end grafting conducting wire.
The buckle-type screw includes buckle head, screw rod, and buckle head is fixed on one end of screw rod, one is provided in buckle head
All grooves.
A kind of application method of buckle-type connection plug, includes the following steps：
1) when the secondary profession of electric system is routinely tested, the terminal screw on voltage and current terminal is disassembled；
2) screw rod of buckle-type screw is screwed into the threaded hole on voltage and current terminal, this operation is disposable behaviour
Make, it is permanent to use；
3) connector lug of test lead is inserted into from connection plug without buckle spring terminal, then the other end of connection plug is inserted
It is sleeved in the buckle head of buckle-type screw, in the groove of buckle head, the opening and closing forces that buckle spring generates will block buckle Spring Card
Discount is fixedly clamped temporarily, and wiring is completed；
4) after the test, directly connection plug is pulled up from buckle-type screw, buckle-type screw stays in terminal
On to wait for next use.
Compared with prior art, the beneficial effects of the invention are as follows：
1) simple in structure, it is at low cost, it is easily installed and dismantles, structural strength is good.
2) testing crew wiring efficiency and stability are improved, effective convenient item is provided for safety in production
Part.

Fig. 2 is the A direction views of Fig. 1；
In figure：1. 2. 3. metallic conduction pipe of buckle spring of the hard plastic that insulate set, 4. buckle-type screw 4-1. buckle heads 4-2.
5. conducting wire of screw rod 4-3. grooves
Specific implementation mode
The present invention is described in detail with reference to the accompanying drawings of the specification, it should be noted that the implementation of the present invention is unlimited
In the following embodiments and the accompanying drawings.
As shown in Figs. 1-2, a kind of buckle-type connection plug, including connection plug, buckle-type screw 4, the connection plug
Including insulation hard plastic set 1, buckle spring 2, metallic conduction pipe 3, the metallic conduction pipe 3 is fixed on insulation hard plastic and covers on 1 inner wall,
It is fixed with buckle spring 2 in one end of 3 inner wall of metallic conduction pipe, the buckle-type screw 4 is screwed onto test voltage current terminal
On；When wiring, the connection plug one end and 4 grafting of buckle-type screw with buckle spring 2 buckle spring 2 by buckle-type
Screw 4 is fixedly clamped, the other end grafting conducting wire 5 of connection plug.
The buckle-type screw 4 includes buckle head 4-1, screw rod 4-2, and buckle head 4-1 is fixed on one end of screw rod 4-2, is blocked
One week groove 4-3 is provided on discount 4-1.
It is metal material with good conductivity to buckle spring 2 and buckle-type screw 4.
A kind of application method of buckle-type connection plug, includes the following steps：
1) when the secondary profession of electric system is routinely tested, the terminal screw on voltage and current terminal is disassembled；
2) the screw rod 4-2 of buckle-type screw 4 is screwed into the threaded hole on voltage and current terminal, this operation is disposable
Operation, it is permanent to use；
3) connector lug of test lead 5 is inserted into from connection plug without buckle spring terminal, then by the other end 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 sleeve, and buckle spring 2 produces
Buckle head 4-1 is fixedly clamped by raw opening and closing forces temporarily, and wiring is completed；
4) after the test, directly connection plug is pulled up from buckle-type screw 4, buckle-type screw 4 stays in end
To wait for next use on son.
A kind of buckle-type connection plug of the present invention is made of connection plug and 4 two parts of buckle-type screw, and connection plug is
The cylindrical tubular shape of inner conductive, exterior insulation, internal one end are equipped with buckle spring 2, the buckle at 4 top of buckle-type screw
Fluted 4-3 is set on head 4-1, and the mode that connection plug is similar to snap-fastener with buckle-type screw 4 is coordinated.
The other end of connection plug is routine test line jack, and test lead 5 only needs the cylindrical hole for being inserted into connection plug
In.The jack of buckle-type connection plug is good and secured with routine test line electric conductivity, the buckle spring 2 in connection plug
Coordinate elastic appropriateness with buckle-type screw 4, both can guarantee that wiring securely overcomes slight touching and the requirement of test lead gravity,
Can guarantee again can will not damage buckle-type screw 4 and terminal block with easy removal using moderate external force.Simultaneously, moreover it is possible to
Good electric conductivity between enough guarantee test conducting wires 5, connection plug, buckle-type screw 4 and terminal block, outside connection plug
The hard plastic that insulate set 1 operates convenient for worker safety, mainly prevention work personnel forget to close experiment output and when reconfiguration line
Auxiliary security protection is played the role of in the personal injury for causing error shock.
The total length appropriateness of connection plug, meets 4 length of buckle-type screw and the protrusion metallic plug length of test lead 5
The sum of, too short then test lead cannot be fully mated with connection plug, is easy to fall off；It is long then due to lever principle, card
The grip of button connection plug needs to overcome 5 gravity of test lead larger.
The present invention is suitable for mode of connection when secondary profession is routinely tested, since second trial is mainly for voltage electricity
Stream terminal carries out input analog quantity, it is only necessary to which original screw on voltage and current terminal is changed to buckle-type screw 4 can be with
Connection plug is used cooperatively, and later buckle-type screw 4 can stay in terminal block, permanent to use.
