Description
Technical field
The utility model relates to electric cable fittings, more specifically to a kind of high cable termination of electric property.
Background technique
Cable termination application places, general headspace is unrestricted, i.e., the external connection of connecting terminal is relative to cable
The height of terminal bottom is unrestricted.
However, the headspace in certain application places cable terminations is subject to certain restrictions, i.e. the wiring of cable termination
The external connection of terminal will receive certain limitation relative to the height of cable termination bottom.Come from the structure of existing cable termination
It sees, the crimping portion of connecting terminal and cable conductor is positioned at the top of terminal body, to increase the whole of cable termination
Body height.So designing by the structure of current cable termination, the height of terminal body can be largely effected on, so as to cause cable termination
External creepage distance can not meet the requirement of electric property.
In addition, not moving after usually cable termination installs, the pressure (such as extraneous wind-force) of receiving is smaller.
However, cable termination needs to bear certain application places (for example cable termination is fixed on a highly mobile object)
A kind of huge external pressure (such as windage), it is necessary to " hard " terminal.Thermal shrinkage type cable termination substrate is plastics, enough " hard ",
But plastics are not soft enough, so, inevitably there is gap at the interface between cable insulation, and climbing electrical breakdown along interface is thermal shrinkage type cable
Terminal accident main cause.
It is therefore desirable to which a kind of (ensure the gapless between cable, and can guarantee cable termination not reducing electric property
External creepage distance) while, the cable termination of energy " rigidity " self-supporting enough.
