Specific embodiment
It is described further below with reference to technical effect of the attached drawing to design of the invention, specific structure and generation, with
It is fully understood from the purpose of the present invention, feature and effect.
(for convenience of discussing, the die sinking such as shell part is omitted in figure) as shown in Figure 1, a kind of secondary loop of mutual inductor is anti-to be opened
Road type system, including 4, male plug needle and female plug needle portion, 4, male plug needle sliding including the first fixing piece 1, insulated spring part 2, conduction
Block 3 and at least a pair of male plug needle 4, in pairs, one of those is used to line of starting to exchange fire to male plug needle 4 with a pair of of male plug needle 4, another
Zero curve and ground line are connect, 4 quantity of male plug needle can be accordingly arranged according to practical application.Male plug needle 4 can be divided into three parts,
Jack end for being connect with current transformer, intermediate needle styletable and the contact pin end for being connect with female plug needle 9, male plug needle
4 are fixed on the first fixing piece 1, are connected with conductive slider 3, therefore conductive slider by insulated spring part 2 on the first fixing piece 1
3 can move back and forth under elastic force and external force.
Conductive slider 3 at spring part reset state (the non-deformed state of reset state not necessarily spring part) with male plug needle
4 are kept in contact connection, therefore keep connection between all male plug needles 4 and be formed into a loop, which forms short-circuit condition, at this time absolutely
The location of edge spring part 2 and conductive slider 3 are set as the reset state of the two.Conductive slider 3 is equipped with through-hole, male plug needle 4
Conductive slider 3 is passed through by through-hole, then male plug needle 4 is fixed on the first fixing piece 1, is connected as conductive slider 3 and male plug needle 4
A kind of embodiment connect, as shown in Figure 1, being connected with conductive ring plate 5 on needle column, it is conductive that conductive ring plate 5 is applied not only to limitation
Sliding block 3 is mobile to 4 contact pin extreme direction of male plug needle, and is set as just tight with the conduction ring plate 5 when 3 reset state of conductive slider
Contiguity touching, to realize the connection of conductive slider 3 Yu male plug needle 4.Meanwhile the other parts of male plug needle 4 do not connect with conductive slider 3
Touching or connection, for this purpose, can be cased with insulation sleeve 6 on 4 needle column of male plug needle, the insulation sleeve 6 is for completely cutting off male plug needle 4 nonisulated
When 2 reset state of spring part with the contact of conductive slider 3.Alternatively embodiment, 4 needle column of male plug needle from jack end to
Contact pin end diameter is gradually increased, and through-hole aperture is greater than at maximum gauge, conductive slider 3 under external force can be between needle column
It slidably reciprocates, when conductive slider 3 is in reset state in being stuck in needle column diameter equal at aperture, conductive slider 3 and male plug needle 4
It directly connects, the increase with hour hands column diameter can play the limit effect for preventing conductive slider 3 mobile to contact pin end.By
In the elastic telescopic of spring part, conductive slider 3 can slidably reciprocate under external force and contact or far from male plug needle 4, thus
Realizing can be connected or disconnected from male plug needle 4.
Female plug needle portion includes the second fixing piece 7, insulation thimble 8 and the female plug needle 9 that matches with male plug needle portion, wherein female plug
Number amount and type of needle 9 etc. are matched with male plug needle 4, and female plug needle 9 and corresponding male plug needle 4 connect one by one；Female plug needle 9 is fixed on
On second fixing piece 7, the second fixing piece 7 is equipped with insulation thimble 8, and insulation thimble 8 is used to connect when male plug needle 4 with female plug needle 9
When push conductive slider 3 far from male plug needle 4 to disconnect the connection (as shown in Figure 3) between conductive slider 3 and male plug needle 4, similarly,
Insulation thimble 8 does not contact and (does not apply added force in conductive slider 3) and is conductive sliding when male plug needle 4 and the disconnection of female plug needle 9 contact
Block 3 connect to which conductive slider 3 returns to reset state with male plug needle 4, it is preferable that in order to guarantee 4 He of male plug needle in use process
Female plug needle 9, which contacts, well avoids male plug needle 4 and the not connected carelessness just used completely of female plug needle 9, i.e. male plug needle 4 and female plug needle 9
The thimble 8 that insulate after being fully connected just opens conductive slider 3 completely, it is therefore desirable to the length of control insulation thimble 8, on being able to achieve
Stating effect is advisable (as shown in Figure 2).Male plug needle 4 and female plug needle 9 are preferably the contact pin of compression joint type, and 9 jack end of female plug needle is coil spring
Formula jack, i.e. 4 contact pin of male plug needle realize connection by the jack of insertion female plug needle 9.Compared to other types of contact pin, the type
Contact pin structure is simpler, connects more convenient.
Using Fig. 1, Fig. 2, Fig. 3 as embodiment, which is exemplified below:
(1) (as shown in Figure 3) when normal use: male plug needle 4 is kept in contact with female plug needle 9, and the thimble 8 that insulate is conductive slider
3 push open, and female plug needle 9 is mutually disconnected and being shorted, and male plug needle 4 is formed into a loop；
(2) when partially unpluging (as shown in Figure 2): conductive slider 3 completely attach to male plug needle 4 formed socket internal short-circuit it
Before, male plug needle 4 is closely kept in contact with female plug needle 9, and conductive slider 3 completely attaches to male plug needle 4 and formed after socket internal short-circuit, public
Contact pin 4 separates again with female plug needle 9；
(3) after unpluging completely (as shown in Figure 1), conductive slider 3 is promoted to male plug needle 4 under the effect of insulated spring part 2, is connect
It touches and compresses, male plug needle dead short, and complete to be grounded.
