There are a large number of on-site secondary system wirings such as power system substations and power distribution rooms. When isolating useless secondary wiring during on-site work, or temporarily disabling some secondary wiring, it is usually detached with insulating tape. The secondary wiring has to be insulated. However, the use of insulating tape has the following disadvantages: 1. The insulating tape is easy to fall off or cause the metal end of the wire to be exposed, which poses a greater safety hazard; When the insulating tape is heated or wrapped for a long time, the adhesive layer is easy to separate and adhere to the metal end of the wire, thus affecting the cleanliness of the secondary wiring.

以上是本发明技术方案的整体描述，下面将结合具体实施例及附图，对本发明实施例中的技术方案进行清楚、完整地描述。The above is the overall description of the technical solutions of the present invention, and the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with specific embodiments and accompanying drawings.
如图4所示，作为第一种实施方式，所述隔离套主体1的内腔为光滑管壁，能直接套置在电线金属端，该种固定方式主要通过其内腔壁与电线包皮层的摩擦实现固定，两者结合的牢固程度并不高，往往容易导致本发明脱落，因此固定效果存在一定缺陷。As shown in Figure 4, as a first implementation, the inner cavity of the spacer main body 1 is a smooth tube wall, which can be directly placed on the metal end of the electric wire. This kind of fixing method is mainly through the inner cavity wall and the wire sheath. The friction between the two is fixed, and the firmness of the combination of the two is not high, which often easily causes the present invention to fall off, so there are certain defects in the fixing effect.
现针对第一种实施方式进行如下改进，如图5和图6所示，所述隔离套主体1开口侧的内腔中设有卡紧件。The following improvements are made to the first embodiment. As shown in FIG. 5 and FIG. 6 , a clamping member is provided in the cavity on the opening side of the spacer main body 1 .
如图5，作为第二种实施方式，所述卡紧件为设置在所述隔离套主体1内腔中的橡胶套11，该所述橡胶套11外侧壁与所述隔离套主体1内侧壁连接固定(可以采用粘结)；这样，所述橡胶套11能够在电线插入时，产生一定挤压形变，从而便于橡胶套11与电线包皮层紧密结合，使两者连接固定更加牢固。As shown in Figure 5, as a second embodiment, the clamping member is a rubber sleeve 11 arranged in the inner cavity of the spacer main body 1, and the outer side wall of the rubber sleeve 11 is connected to the inner side wall of the spacer main body 1. Connection and fixation (bonding can be used); in this way, the rubber sheath 11 can produce a certain extrusion deformation when the wire is inserted, thereby facilitating the tight combination of the rubber sheath 11 and the wire sheath, making the connection and fixing of the two more firm.
如图6所示，作为第三种实施方式，所述卡紧件为设置在所述隔离套主体1内腔中的第一凸体11′，所述第一凸起11′为光滑的环形结构；这样，在电线插入时，第一凸体11′对电线包皮层进行挤压使其产生一定形变，从而便于第一凸体11′与电线包皮层紧密结合，使两者连接固定更加牢固。As shown in Figure 6, as a third embodiment, the clamping member is a first protrusion 11' disposed in the inner cavity of the spacer main body 1, and the first protrusion 11' is a smooth ring shape. structure; in this way, when the wire is inserted, the first convex body 11' squeezes the wire sheath layer to cause a certain deformation, thereby facilitating the close combination of the first convex body 11' and the wire sheath layer, making the connection and fixing of the two more firm .
进一步地，所述第一凸起11′沿轴向可以设置成均匀分布的多个，从而起到更好的连接固定效果。Further, the first protrusions 11' can be arranged in multiples evenly distributed along the axial direction, so as to achieve a better connection and fixing effect.
如图7至图9所示，作为上述三种实施方式的进一步改进，所述定位套12外侧设有橡胶端盖121，所述橡胶端盖121中心处设有与所述隔离套主体1内腔同轴的通孔1211，所述通孔1211的孔径小于所述隔离套主体1的内腔孔径；这样，在电线插入后，所述通孔1211受挤压产生弹性形变，并与电线包皮层紧密结合，从而进一步改善固定效果；而且，此种方式在潮气较大的地方还能够具有较好的防潮效果。As shown in Figures 7 to 9, as a further improvement of the above three embodiments, a rubber end cover 121 is provided on the outside of the positioning sleeve 12, and a cavity coaxial through hole 1211, the aperture of the through hole 1211 is smaller than the inner cavity aperture of the spacer main body 1; like this, after the wire is inserted, the through hole 1211 is extruded to produce elastic deformation, and is connected with the wire sheath The layers are closely combined, thereby further improving the fixing effect; moreover, this method can also have a better moisture-proof effect in places with high humidity.
更进一步地，由于所述通孔1211的孔径小于所述隔离套主体1的内腔孔径，即所述通孔1211的孔径也小于所述电线的包皮层外径，为使电线插入比较方便，所述通孔1211外侧设有向外延伸的第一锥形口1211′。Furthermore, since the aperture of the through hole 1211 is smaller than the inner diameter of the spacer main body 1, that is, the aperture of the through hole 1211 is also smaller than the outer diameter of the sheath layer of the electric wire, in order to facilitate the insertion of the electric wire, A first tapered opening 1211 ′ extending outward is formed outside the through hole 1211 .
此外，为使本发明在夜晚具有警示作用，所述隔离套主体1外侧还可以设有在夜晚能够发光的荧光条，该荧光条可以利用粘贴的方式设置在所述隔离套主体1外侧面上，由于荧光条为现有技术，本技术领域技术人员可以很容易实现，在此不再详细描述。In addition, in order to make the present invention have a warning function at night, the outer side of the spacer main body 1 can also be provided with a fluorescent strip that can emit light at night, and the fluorescent strip can be arranged on the outer surface of the spacer main body 1 by pasting. , since the fluorescent strip is a prior art, it can be easily realized by those skilled in the art, and will not be described in detail here.
除说明书所述的技术特征外，均为本专业技术人员的已知技术。Except for the technical features described in the instructions, all are known technologies by those skilled in the art.
以上所述结合附图对本发明的优选实施方式和实施例作了详述，但是本发明并不局限于上述实施方式和实施例，对于本技术领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干改进和变型，这些改进和变型也应视为本发明的保护范围。The above described the preferred embodiments and embodiments of the present invention in detail in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments and embodiments, for those of ordinary skill in the art, without departing from the present invention Under the premise of the concept, several improvements and modifications can also be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
