The following description of the embodiments of the utility model with reference to the drawings is intended to illustrate the general inventive concept and should not be taken as limiting the utility model.

Furthermore, in the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the disclosure. It may be evident, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are shown in schematic form in order to simplify the drawing.

According to one general technical concept of the present invention, there is provided a connection assembly for connecting high voltage cables, the connection assembly including: the thread fixing piece is used for fixedly connecting the high-voltage cable to the matching connecting part and comprises an insulating piece; and a conductive plug provided in connection with the insulator so that the threaded fastener can be tightened or loosened by rotating the conductive plug.

According to another general technical concept of the present invention, there is provided a connector, including: a conductive housing having a mounting hole; an inner insulator mounted into the conductive shell; a terminal provided to the inner insulator; a counter-threaded connector provided to the inner insulator; and the connecting assembly enters the conductive shell through the mounting hole and is mutually connected with the matching threaded connecting piece, and is used for electrically connecting the terminal to a high-voltage cable.

Fig. 1 shows a perspective view of a connector according to an exemplary embodiment of the present invention. Fig. 2 shows a cross-sectional view of the connector shown in fig. 1. Fig. 3 shows a perspective view of a connector according to an exemplary embodiment of the present invention with conductive shell 100 removed. Fig. 7 shows an exploded view of a connector according to an exemplary embodiment of the present invention.

As shown in fig. 1-3 and 7, in the illustrated embodiment, the connector essentially comprises: a conductive shell 100, an inner insulator 200, a terminal 20, a threaded connector 30, a mating threaded connector 40, a conductive plug 60, a resilient sealing sleeve 70 and an insulator 50. The conductive housing 100 has a mounting hole 101. The inner insulator 200 is installed into the conductive shell 100. The terminal 20 is provided to an inner insulator 200, and the inner insulator 200 serves to hold the terminal 20 and to electrically isolate the terminal 20 from the conductive shell 100.

FIG. 8 shows an assembled view of the connection assembly in the connector shown in FIG. 1; FIG. 9 shows a cross-sectional view of the connection assembly shown in FIG. 8; fig. 10 shows an exploded view of the connection assembly shown in fig. 8.

As shown in fig. 1-3 and 7-10, in the illustrated embodiment, the threaded connector 30, the conductive plug 60, and the insulator 50 form a connecting assembly. The connecting assembly enters the conductive housing 100 through the mounting hole 101 of the conductive housing 100. The threaded connector 30 of the connection assembly is threadedly connected with the mating threaded connector 40 for electrically connecting the terminal 20 to the cable terminal 10. In the illustrated embodiment, one end 11 of the cable terminal 10 is crimped onto a conductor of the high voltage cable 1, and the other end 12 is connected to one end 22 of a terminal 20 of a connector. In this way, the terminal 20 of the connector is connected to the high voltage cable 1. Although not shown, the connector further includes a shield connector mounted in the conductive housing 100 for electrically connecting the shield layer of the high voltage cable 1 to the conductive housing 100. For example, the shielding connector may be a conductive ring sleeved on the shielding layer of the high voltage cable 1, and the conductive ring has a conductive elastic piece, which is in point contact with the inner wall surface of the conductive housing 100. If waterproof is desired, the connector also includes a sealing ring disposed between the conductive shell 100 and the high voltage cable to seal the mating interface therebetween.

As shown in fig. 1-3 and 7-10, in the illustrated embodiment, the conductive plugs 60 are disposed in the mounting holes 101 for plugging the mounting holes 101 to perform an electromagnetic shielding function. The elastic sealing boot 70 is fitted over the conductive plug 60 and seals a gap between the conductive plug 60 and the conductive housing 100 to achieve a waterproof function. Note that the elastomeric sealing boot 70 may be omitted if the installation environment does not require waterproofing. The insulator 50 is engaged between and electrically isolates the conductive plug 60 and the threaded connector 30 so that the threaded

connectors

30, 40 can be tightened or loosened by rotating the conductive plug 60. In the illustrated embodiment, the threaded connector 30 is electrically conductive, and the insulator 50 prevents an operator from contacting the electrically conductive threaded connector 30.

As shown in fig. 1 to 3 and 7, in the illustrated embodiment, in order to enable the electromagnetic shielding function, the gap between the conductive plug 60 and the conductive housing 100 is sized to prevent electromagnetic waves from leaking to the outside of the conductive housing 100 through the gap. The size of the gap between the conductive plug 60 and the conductive shell 100 includes two dimensions, one being the width of the gap and the other being the length of the gap. The sizes of the two dimensions can be set reasonably according to the wavelength of the electromagnetic wave.

As shown in fig. 1-3 and 7, in the illustrated embodiment, the elastomeric sealing boot 70 may be made of a generally elastomeric material, such as rubber. Such an elastic sealing sleeve 70 usually has only a waterproof function and no conductive function. However, the present invention is not limited thereto, and for example, in one exemplary embodiment of the present invention, the elastic sealing boot 70 may be an elastic conductive seal made of an elastic conductive material, so that the conductive plug 60 can be electrically connected to the conductive housing 100 via the elastic sealing boot 70. Thus, the electromagnetic shielding effect of the connector can be further improved.

As shown in fig. 2 and 8-10, in an exemplary embodiment of the present invention, the insulator 50 may be injection molded onto the threaded

connectors

30, 40 and the conductive plug 60 simultaneously. In this way, the insulator 50 can be coupled to both the threaded connector 30 and the conductive plug 60. However, the present invention is not limited thereto, and for example, in another exemplary embodiment of the present invention, the insulating member 50 may be separately formed from the threaded connector 30 and the conductive plug 60 and fitted over the threaded connector 30 and the conductive plug 60. Alternatively, in another exemplary embodiment of the present invention, the insulator 50 may be formed on one of the threaded connector 30 and the conductive plug 60 and fitted over the other of the threaded connector 30 and the conductive plug 60.

An annular groove 61a is formed on one of the inner wall of the insulating member 50 and the outer wall of the conductive plug 60, and an annular projection adapted to engage with the annular groove 61a is formed on the other. When the insulator 50 is fitted over the conductive plug 60, the annular groove 61a engages with the annular projection to prevent the conductive plug 60 from axially separating from the insulator 50.

As shown in fig. 2 and 8-10, in the illustrated embodiment, the insulator 50 includes: a circumferential insulation portion 51 and an intermediate boss portion 52. The intermediate boss 52 is located in the circumferential insulating portion 51 and connected to the circumferential insulating portion 51. The conductive plug 60 is engaged between the circumferential insulating portion 51 and the intermediate boss 52 of the insulator 50 so that the conductive plug 60 cannot rotate relative to the insulator 50. The threaded connector 30 is engaged into the intermediate boss 52 of the insulator 50 such that the threaded connector 30 cannot rotate relative to the insulator 50.

As shown in fig. 2 and 8-10, in the illustrated embodiment, the insulator 50 is injection molded onto the threaded connector 30. The insulator 50 and the threaded connector 30 together form a threaded fastener.

As shown in fig. 2 and 8 to 10, in the illustrated embodiment, the threaded connector 30 is a bolt, the mating threaded connector 40 is a nut, and the bolt is formed with an external thread 33 to be threadedly coupled with the nut. The head 31 of the bolt is engaged into the insulator 50 and the nut is fixed to the terminal 20. The bolt passes through the cable terminal 10 and the terminal 20 of the connector and is screwed with the nut to electrically connect the cable terminal 10 and the terminal 20 of the connector together. In the illustrated embodiment, the bolt can be rotated by rotating the conductive plug 60 so that the bolt can be tightened or loosened.

It is noted, however, that the present invention is not limited to the illustrated embodiment, for example, in another exemplary embodiment of the present invention, the threaded connector 30 is a nut and the counter threaded connector 40 is a bolt. The nut is engaged into the insulator 50 and the head 31 of the bolt is fixed to the terminal 20. The bolt passes through the cable terminal 10 and the terminal 20 of the connector and is screwed with the nut to electrically connect the cable terminal 10 and the terminal 20 of the connector together.

As shown in fig. 2 and 8-10, in the illustrated embodiment, the connector further includes an insulative cap 90 that fits over the end 32 of the bolt 30 opposite the head 31 to prevent an operator from contacting the end 32 of the bolt 30. Thus, electric shock accidents can be prevented.

As shown in fig. 2 and 8-10, in the illustrated embodiment, a blind slot hole 63 is formed on the outer end of the conductive plug 60, the blind slot hole 63 being adapted to engage with an external tool (not shown) so that the conductive plug 60 can be driven in rotation by the external tool. In this way, the threaded connection 30 can be tightened or loosened.

As shown in fig. 1-3 and 8-10, in the illustrated embodiment, the conductive plug 60 includes a cylindrical body portion 61 and the elastomeric sealing boot 70 includes a cylindrical body portion 71. The cylindrical body portion 71 is fitted over the cylindrical body portion 61 and is radially compressed between the cylindrical body portion 61 of the conductive plug 60 and the inner wall of the mounting hole 101 to seal a gap therebetween.

As shown in fig. 1-3 and 8-10, in the illustrated embodiment, the conductive plug 60 further includes an annular brim portion 62 formed at an outer end of the cylindrical body portion 61, and the elastomeric seal cartridge 70 further includes a radially extending annular lip portion 72 formed at one end of the cylindrical body portion 71. The annular lip portion 72 of the elastomeric sealing boot 70 is axially compressed between the annular brim portion 62 of the conductive plug 60 and the outer surface of the conductive housing 100 to seal the gap therebetween.

As shown in fig. 1-3 and 8-10, in the illustrated embodiment, the connector further includes an elastomeric seal 80 disposed at the bottom of the conductive shell 100. The elastomeric seal 80 is compressed between the conductive shell 100 of the connector and the housing of the electrical device to seal the mating interface therebetween when the conductive shell 100 of the connector is mounted to the housing of the electrical device.
