Specific embodiment

Referring to Fig. 1, equipment locking device comprising: terminal plate 100 and wire clamp component 200；Wherein, the terminal plate 100 for connecting power switch, and the wire clamp component 200 is used for connecting wire.

Wherein, the wire clamp component 200 includes wire clamp seat 210 and crimping bolt 220.

The wire clamp seat 210 is equipped with clamp hole 211 and bolt hole 212, and the clamp hole 211 and bolt hole 212 are mutual It is vertical and interconnected.

As shown in Figure 3 and Figure 4, the crimping bolt 220 includes sequentially connected first rotating part 221, connection thin slice 222 With threaded joints 223, the threaded joints 223 are connected in the bolt hole 212, and when the first rotating part 221 and spiral shell When line interconnecting piece 223 relatively rotates, connection thin slice 222 is twisted off.

In the present embodiment, the first rotating part is hexagon bolt head, threaded joints be with the matched screw rod of bolt hole, Connection thin slice is the circle circular ring shape thin slice being connected on hexagon bolt head；In actual production, the first rotating part, connection are thin Piece and threaded joints are integrated chemical conversion type.

When wiring, the rotation of the first rotating part is driven by spanner or other tools, so that threaded joints be driven to screw in In clamp hole；When threaded joints are due to frictional force inhibition by conducting wire, velocity of rotation can be than the first rotating part Velocity of rotation it is slower and slower, at this time connect thin slice both ends be not rotate synchronously, then connect thin slice by a torsion, but the torsion When power reaches certain numerical value, connection thin slice is twisted off；This means that the conducting wire portion of being threadably coupled compresses, operator is not necessarily to Hold-down bolt is further screwed, so that conducting wire be avoided to cause excessive damage.

As shown in Figure 3, it is preferable that be additionally provided with the second rotating part between the connection thin slice 222 and threaded joints 223 224。

Second rotating part is hexagon bolt head identical with the first rotating part；After clamping conducting wire, connection thin slice is turned round It is disconnected, separate the first rotating part with threaded joints, in order to facilitate the operation of the connection of personnel's release conducting wire and clip part, by The second rotating part is set between connection thin slice and threaded joints, then operator can use spanner or other tools are clamped Second connecting portion makes threaded joints screw out bolt hole outward.

As shown in Figure 1, Figure 2 and shown in Fig. 5, it is preferable that be arranged with protection cushion rubber 225 on the peripheral part of the connection thin slice 222.

Since connection thin slice has the characteristic that can be twisted off, so its intensity is compared to the first rotating part, the second rotation The intensity of portion and threaded joints wants weak；In order to avoid connection thin slice is destroyed in a non-operative state, it is therefore necessary to even One protection cushion rubber of setting on the peripheral part of thin slice is connect, which plays buffering in the state of connecting thin slice and being impacted Effect.

Specifically, the outer diameter of the protection cushion rubber 225 is greater than the outer diameter of first rotating part 221.
