Problems solved by technology
In the first case, there are defects such as complex structure and incompatibility of front and rear insertion; in the second case, the shortcomings of the epoxy double-way bushing are limited flow capacity, insufficient insulation strength, strict requirements on the installation process, and Different materials of separable connectors make interface performance unstable
The expansion of the above-mentioned separable connectors is realized through two or more separable connectors. The above detachable connectors occupy a large space and cannot meet the needs of expansion in a small space

Embodiment
[0029] The extension of the 10kV cable is taken as an example to explain below.
[0030] The structure of the novel connector of the present invention is as figure 1 with figure 2 As shown, it includes: a separable connector body 3 and a conductive rod 2 for realizing electrical connection; the separable connector body 3 refers to a casing well including two identical cable outlet cavities 9 and an intermediate cavity 10, The casing well is made of silicone rubber insulating material; the cable outlet cavity 9 communicates with the intermediate cavity 10 and the outside respectively; the intermediate cavity 10 is provided with a first opening 11 and a second opening 12 communicating with the outside, the first opening 11 The same shape as the second opening 12; the angle between the two cable lead-out cavities 9 is 180°; the two cable lead-out cavities 9 are provided with a stress cone structure; the cable lead-out cavity 9 is connected to the cable and the cable front end i...

The invention relates to a novel separable connector which comprises a separable connector body and a conducting rod used for realizing electric connection. The separable connector body is a cased well comprising at least two identical cable leading-out cavities and one middle cavity, and the cable leading-out cavities are respectively communicated with the middle cavity and the exterior; the middle cavity is provided with a first opening and a second opening communicated with the exterior; and both ends of the connecting rod are provided with connecting structures. The connector is assembledas follows: one end of the conducting rod is connected with a casing of a switch cabinet, cables are inserted into the cable leading-out cavities, conducting terminals at the front ends of the cablesstretch into the middle cavity, and through holes on all the conducting terminals are aligned. The separable connector body together with the cables is sheathed outside the conducting rod through a first or second opening. At the moment, the conducting terminals at the front ends of the cables are sheathed on the rod body of the conducting rod in sequence through the through holes on the conducting terminals and are tightly matched. More than two cables can be led out with one separable connector at the same time, and occupied space is greatly saved.
Description
technical field [0001] The invention relates to a power cable accessory, in particular to a novel outer cone separable connector and its usage method. Background technique [0002] The connector is suitable for the incoming and outgoing line terminals of the ring network switchgear, and is connected to the insulating seat of the switch. It is also suitable for various cable branch boxes and box-type substation devices, and can also be used for the incoming and outgoing line connection of the transformer. With the transformation and expansion of urban power grids, higher requirements are placed on separable connectors. There are two main ways to expand the existing separable connectors of various voltage levels: the first is to directly use the rear plug-in separable connector to connect to the front plug-in separable connector, so as to realize the separable The expansion of the connector; the second is to use the epoxy double-way sleeve as the intermediate connector to rea...
