Abstract

The invention relates to the technical field of cable intermediate head connecting devices, and particularly discloses a cable intermediate head connecting device. The device is used for connecting end cells of two cables and comprises an outer connecting pipe, an inner connecting pipe a, an inner connecting pipe b and a plurality of bolts. Firstly, end battery cells of two cables are inserted into the inner connecting pipe a and the inner connecting pipe b respectively, then the inner connecting pipe a and the inner connecting pipe b are inserted into the outer connecting pipe from the two ends of the outer connecting pipe respectively, and finally the inner connecting pipe a and the inner connecting pipe b abut against the inner connecting pipe a and the inner connecting pipe b through bolts respectively, so that the inner connecting pipe a and the inner connecting pipe b can be fixed into the outer connecting pipe respectively. When the device abuts against the inner connecting pipe a and the inner connecting pipe b in the outer connecting pipe through a plurality of bolts, no burrs occur, and the service life of the cable intermediate head is not affected.

Example Embodiment

[0041] Example 2

[0042] The present embodiment is substantially the same as that of the Example, and the only difference is that the outer wall concave along the axial wall of the inner connection tube A2 is concave, with a plurality of limit recess a, with a plurality of outer walls of the inner connection tube B3 The limit recess B is provided with a plurality of limit pins along the axial inner wall of the outer connecting tube 1.

[0043] When the inner connecting tube A2 and the inner connecting tube B3 are each inserted from the outer end of the outer end of the connecting pipe 1, the plurality of limit recess A and the concave in the interconnection are concave at both ends of the inner connection tube A2, respectively. The plurality of limit grooves B on B3 are inserted with a limiting pin that is protruded on the outer connecting tube 1, respectively. In the present embodiment, the plurality of limit recess b on the plurality of limit recess a and the inner connection tube B3 on the inner connection tube A2 correspond to the plurality of limit pins on the outer linear tube 1 and mutually Plug, this setting prevents the inner connection tube A2 and the inner connecting tube B3 to rotate the axis of the outer connecting tube 1 in the outer connecting tube 1, respectively.
