Description
Technical field
The utility model is related to field of test instrument, especially a kind of prod of band insurance.
Background technology
In instrument test in use, detection high current article is frequently encountered, during instrument test, because flowing through
The electric current of instrument is excessive, often causes the damage of instrument, and test job is caused not carry out normally, and fuse is that people use
An important component of electric appliance is protected when reply electric current is excessive；Therefore, it is necessary to knot of the combination fuse in ground to test equipment
Structure is improved.
Utility model content
The utility model is insufficient in view of the above technology, provides one kind and adding a fuse inside prod, encounters big electricity
When stream, fuse can first break to protect instrument, the prod of the risk of lowering apparatus damage.
In order to achieve the above objectives, the utility model is achieved through the following technical solutions：
A kind of prod of band insurance, including the first shell and second housing, first shell are set in second housing
It is interior, the first hardware terminal is equipped in the cavity of first case nose, the rear end of first hardware terminal is solid equipped with spring
Reservation, the spring fixed seat is interior to be equipped with spring, and fuse, the insurance are equipped in the first cavity pocket of outer cover of the spring rear end
The rear end of silk is equipped with fuse fixed seat, is equipped with the second hardware terminal in the cavity of the second housing rear end, and the described 2nd 5
The front end of golden terminal is connected with fuse fixed seat.
Further, the front end of first shell is equipped with external screw thread, and the front inner wall of the second housing is equipped with interior spiral shell
Line.
Further, the interior sidewall surface of first shell is equipped with convex block.
Further, first hardware terminal is a center needle made of beryllium copper.
Further, second hardware terminal is a copper pipe.
The beneficial effects of the utility model are：
Add a fuse inside prod, when encountering high current, fuse can first break to protect instrument, drop
The risk of low instrument damage.
It is convenient that fuse is replaced, cheap, protects instrument and meter well.Reduce customer using cost.
The interior sidewall surface of first shell is equipped with convex block, can be defined to the position of fuse, avoids sending out because of fuse
Life shifts and can not occur the case where fuse protection instrument when encountering high current, while being played to spring after blown fuse
The effect of support and positioning.
Description of the drawings
Fig. 1 is the overall structure diagram of the utility model.
Fig. 2 is the structural schematic diagram of the first shell and its inner body.
Fig. 3 is the structural schematic diagram of second housing and its inner body.
In figure, the first shell 1, second housing 2, the first hardware terminal 3, spring fixed seat 4, spring 6, external screw thread 7, interior spiral shell
Line 8, fuse 9, fuse fixed seat 10, the second hardware terminal 11, convex block 12.
Specific implementation mode
As shown in the combinations of Fig. 1~3, a kind of prod of band insurance, including the first shell 1 and second housing 2, described first
Shell 1 is set in second housing 2, is equipped with the first hardware terminal 3 in the cavity of 1 front end of the first shell, and the described 1st
The rear end of golden terminal 3 is equipped with spring fixed seat 4, is equipped with spring 6 in the spring fixed seat 4,6 rear end of the spring first outside
Fuse 9 is equipped in 1 cavity of shell, the rear end of the fuse 9 is equipped with fuse fixed seat 10,2 rear end of the second housing
The second hardware terminal 11 is equipped in cavity, the front end of second hardware terminal 11 is connected with fuse fixed seat 10, described
The front end of first shell 1 is equipped with external screw thread 7, and the front inner wall of the second housing 2 is equipped with internal thread 8, first shell 1
Interior sidewall surface be equipped with convex block 12, first hardware terminal 3 be a center needle made of beryllium copper, second hardware end
Son 11 is a copper pipe.
By the cooperation between external screw thread 7 and internal thread 8, the posterior part of the first shell 1 is made to coordinate in second housing 2
Interior, the spring 6 in reset condition is in compressive state, and pushes the first hardware terminal 3 forward, when fuse 9 encounters big electricity
When stream fusing, spring 6 is restored to original state and mobile to the position of former fuse 9 and extend, when spring 6 extends to convex block 12
When place, spring 6 continues extension and movement by the limitation of convex block 12, but the front end of spring 6 continues to press on the first hardware terminal 3 forward,
After the fusing of fuse 9, it is in disengaged position between the first hardware terminal 3 and the second hardware terminal 11, waits reinstalling guarantor
After dangerous silk 9, reconnected between the first hardware terminal 3 and the second hardware terminal 11.
Adding a fuse 9 inside prod, when encountering high current, fuse 9 can first break to protect instrument,
The risk of lowering apparatus damage.
It is convenient that fuse 9 is replaced, cheap, protects instrument and meter well.Reduce customer using cost.
The interior sidewall surface of first shell 1 is equipped with convex block 12, can be defined to the position of fuse 9, avoids because of insurance
Silk 9 is displaced and can not occur the case where fuse protection instrument when encountering high current, while to bullet after the fusing of fuse 9
Spring 6 plays the role of support and positioning.
In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped
Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should
It considers the specification as a whole, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
The other embodiment being appreciated that.
