By the holding of elastic block piece 3, the connection between fuse tube 7 and circuit can be effectively prevent to loosen, ensure that connecing for fuse
Entering circuit being capable of stable operation.
The working condition of fuse is checked in order to facilitate staff, and staff is allowed to find the need of fuse tube 7 in time
The case where replacing, the fuse tube 7 are also associated with status display circuit, the status display circuit include bi-colour LED 1,
Resistance and unipolar tube, as shown in Figure 2 and shown in Fig. 3, the first pin and third pin of the bi-colour LED 1 are connected to molten
One end of disconnected pipe 7, the second pin of the bi-colour LED 1 are connected to the other end of fuse tube 7 through resistance and unipolar tube.In this way
When fuse tube 7 is not burnt out, bi-colour LED 1 gives a green light, and bi-colour LED 1 sends out a warning after fuse tube 7 has been burnt out, and reminds
Staff replaces fuse tube 7 in time, does not need staff and investigates fault, more hommization everywhere.
As shown in Figure 2, all parts of status display circuit are all disposed within inside handle 5, it is right at the top of handle 5
Answer bi-colour LED that the capping 53 of one light transmission is set, such people can pass through the light feelings of 53 observation bi-colour LED 1 of capping
Condition, while can also prevent the foreign matters such as liquid or dust from entering inside status display circuit, fuse, which has been effectively ensured, to be stablized
The operation of safety.
As shown in Figure 1,41 rectangular setting of the accommodating cavity, described to open up two connections respectively in the bottom of accommodating cavity 41
The button 23 of hole and a power supply source switch extends to the hole in accommodating cavity 41, and power switch 2 is preferably provided at the bottom of shell 4
Or other sides, while the outlet terminal 21 on fuse being exposed for staff's wiring.
There is the handle 5 hand for gripping portion 51 and the mounting portion 52 for installing fuse tube 7, the hand to be taken to take portion
51 are fixed with buffering compression spring 8, and one end of the buffer spring is fixedly connected with mounting blocks 6, and the conductive pin 9 is set to buffering elastic
The other end of spring, the mounting portion be equipped with for grip fuse tube both ends to folder shrapnel 71 (in order to ensure fuse tube 7
The electric conductivity with conductive pin 9, position setting that should be at the both ends that mounting groove corresponds to installation fuse tube 7 is corresponding conductive
Then conductive sheet is electrically connected by piece by conducting wire or other conducting elements with conductive pin 9, due to realization method have it is more
Kind, details are not described herein again).The clamping of fuse tube 7 can facilitate staff to remove replacement in folder spring, buffering compression spring 8
The elasticity that connects between the allotment conductive pin 9 and lead-in wire terminal 22 for capableing of elasticity is set, while can allow power switch
Pressure on button 23 is gentler, will not damage button because of excessive, and fuse tube 7 will not be caused to access because of too small
It is unstable, the stable operation of circuit is effectively ensured.
As shown in Figures 2 and 3, the bottom of the mounting portion is equipped with pressing structure 6, and the pressing structure 6 includes pressing lever
61, spring 62 and the rebound chamber 63 set on press section bottom are contradicted, 61 one end of the pressing lever is arranged in rebound chamber 63, another
End can with the press-side of button contradict connect, the conflicts spring 62 be set to spring back chamber 63 in, and its both ends respectively with rebound
Chamber 63 and pressing lever 61 contradict connection.It contradicts spring 62 to be used for pressing lever 61 supporting out rebound chamber 63, pressing lever 61 is used for direct
The press-side of button is pressed, in this way when assembling handle and shell, press-side can be allowed to be constantly in moderately good connect
Logical state, pressing lever 61 is detached from pressing conduction state with button after pulling out handle.
In order to ensure the secured connection of handle 5 and shell 4, as shown in Figure 2 and Figure 4, the two sides of the handle 5 are equipped with bullet
Property fixture block 10 (10 end set of elastic clamping block is unidirectional tooth 101 in figure, and elastic clamping block 10 and hand take between portion 51 that there are pressings
Gap is pressed for people's hand to take out handle 5), the accommodating cavity 41 is equipped with the card slot 42 for being clamped with elastic clamping block 10.For
Facilitate people to take out handle 5, several concave convex textures are preferably set on elastic clamping block 10, increases between people's hand and handle 5
Friction, the taking-up of handle 5 is more convenient.
The hand takes corresponding two elastic clamping blocks in portion to be equipped with supplementary structure 11, as shown in figure 4, the supplementary structure 11 wraps
Include mandril 111, secondary spring 112 and determine spring base 113, it is described determine spring base 113 be fixed at hand take portion, the mandril 111
One end, which is actively located in, determines in spring base 113, and the other end is contradicted with elastic clamping block and connected, and the mandril 111 is set to hand and takes in portion
One end be fixed with flexible spring seat 114, the secondary spring 112 is arranged on mandril 111 and both ends contradict determine spring respectively
Seat 113 and flexible spring seat 114.
Mandril 111 in this way can be constantly in conflict state, by bullet due to there is the conflict of secondary spring 112 with elastic clamping block
Property fixture block be clamped in card slot 42 pushing rod 111 and contradict elastic clamping block, the connection between additional reinforcement handle and shell；It needs to take
Elastic clamping block is pressed when going out handle, mandril 111 is inwardly squeezed while being compressed secondary spring 112 by elastic clamping block, thus will
Handle takes out, and unclamps the pressure release of secondary spring 112 after elastic clamping block；When assembling handle to shell again, auxiliary
Spring 112 can quickly be discharged after compression of the elastic clamping block through mandril 111 and elastic clamping block is firmly caught in card slot
In 42, effectively play the role of auxiliary clamping.
