Abstract
The utility model discloses a current overload safety device, and belongs to a current safety device, in order to provide a current safety device with high touch reliability. The current overload safety device comprises a shell, a safety core positioned in the shell and wiring terminals which are respectively connected with two ends of the safety core electrically; the wiring terminals are provided with hole-type joints, and are connected with the safety core (4) through a bolt (3). The current overload safety device provided by the utility model has the advantages of simple structure, good touch reliability, high operation current and the like, and is a current safety device suitable for engineering machinery.
Description
Technical field
The utility model relates to a kind of safeties, relates in particular to a kind of electric current safeties.
Background technology
At present, the current overload of engineering machinery insurance device usually by shell, be arranged in the insurance core of this shell, the binding post that is electrically connected with these insurance core two ends respectively constitutes; Because the current overload of traditional structure insurance device is through spring binding post to be compressed with the insurance core to contact, therefore under the judder effect, be easy to generate and become flexible and cause loose contact, influence the engineering machinery normal operation.
Summary of the invention
In order to overcome the defective that exists in the prior art, the utility model aims to provide the high current overload insurance device of a kind of contact reliability.
To achieve these goals, the utility model adopts following technical scheme: the binding post that it comprises shell, is arranged in the insurance core of this shell, is electrically connected with these insurance core two ends respectively; Binding post is an eyelet terminal, and this binding post is connected with the insurance core through bolt.
One end of shell has through screw thread end cap fixed thereon.
Compare with prior art; The utility model is owing to adopted technique scheme; Even if therefore engineering machinery produces judder, binding post also can remain good the contact with the insurance core, has advantages such as simple in structure, that contact reliability good, operating current is big.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of conventional current overload safety device.
Among the figure: end cap 1 shell 2 bolts 3 insurance cores 4 binding posts 5 leads 6 springs 7
Embodiment
Below in conjunction with accompanying drawing and concrete embodiment the utility model is described further:
As shown in Figure 1: insurance core 4 is arranged in 2, two binding posts 5 of shell are separately fixed at this insurance core 4 separately through bolt 3 two ends, and binding post 5 is connected with lead 6 respectively; In order to guarantee that binding post 5 reliably is connected with lead 6, binding post 5 adopts eyelet terminal.Deviate from for fear of binding post 5, have through screw thread end cap 1 fixed thereon at an end of shell 2.
Comparison diagram 2 can be found out: the current overload insurance device of traditional structure is under the effect of judder, and spring 7 is difficult to guarantee that binding post 5 holds out against all the time on insurance core 4, and contact reliability is relatively poor.
Claims (2)
1. a current overload insures device, the binding post that comprises shell, is arranged in the insurance core of this shell, is electrically connected with these insurance core two ends respectively; It is characterized in that: binding post (5) is an eyelet terminal, and this binding post is connected with insurance core (4) through bolt (3).
2. current overload insurance device according to claim 1, it is characterized in that: an end of shell (2) has through screw thread end cap fixed thereon (1).
