In some embodiments, as shown in fig. 1 to 4, a first end of the first threading hole 231 protrudes with respect to an upper surface of the threading plate 230, a second end of the first threading hole 231 protrudes with respect to a lower surface of the threading plate 230, an end diameter of the first threading hole 231 is less than or equal to a diameter of the cable, and a middle diameter of the first threading hole 231 is greater than both end diameters of the first threading hole 231.

As shown in fig. 1 to fig. 4, the first end of the first threading hole 231 is an end of the first threading hole 231 near the conductive member 210, and the second end of the first threading hole 231 is an end of the first threading hole 231 facing away from the conductive member 210.

As shown in fig. 1 to 4, the overall height of the first threading hole 231 is greater than the height of the threading plate 230, that is, both ends of the first threading hole 231 protrude outwards with respect to the upper and lower surfaces of the threading plate 230, respectively, the diameter of the first end of the first threading hole 231 is smaller than the diameter of the middle of the first threading hole 231, and the first end of the first threading hole 231 is connected with the middle of the first threading hole 231 through the tapered connection structure 232, the diameter of the second end of the first threading hole 231 is smaller than the diameter of the middle of the first threading hole 231, and the second end of the first threading hole 231 is connected with the middle of the first threading hole 231 through the tapered connection structure 232, the tapered connection structure 232 is made of the same material as the threading plate 230, and the thickness of the tapered connection structure 232 may be smaller than the thickness of the Yu Chuanxian plate 230.

As shown in fig. 1 to 4, at least one of the first and second ends of the first threading hole 231 has a diameter smaller than that of the cable, for example, both the first and second ends of the first threading hole 231 have a diameter smaller than that of the cable.

In the actual implementation process, the end of the cable sequentially passes through the second end and the first end of the first threading hole 231 and then enters the accommodating cavity of the mounting seat 220, when the cable passes through the second end of the first threading hole 231, the tapered connection structure 232 between the second end and the middle of the first threading hole 231 retracts upwards, the diameter of the second end increases, and when the cable passes through the first end of the first threading hole 231, the diameter of the first end of the first threading hole 231 increases.

Through the first end, the second end and the tapered connection structure 232 of the threading hole, space can be provided for the elastic deformation of the tapered connection structure 232 of the threading plate 230, so that the diameters of the first end and the second end of the first threading hole 231 can be increased, namely, the end part of the threading hole can penetrate through the first end and the second end of the first threading hole 231 under the condition of using smaller external force, and the installation efficiency is improved.

In some embodiments, as shown in fig. 1-4, the diameter of the first end is smaller than the diameter of the second end.

1-4, The first end diameter and the second end diameter of the first threading hole 231 are smaller than the diameter of the cable, and the first end diameter of the first threading hole 231 is smaller than the second end diameter.

In the actual implementation process, the cable end sequentially passes through the second end and the first end of the first threading hole 231, and since the diameter of the first end and the diameter of the second end of the first threading hole 231 are smaller than the diameter of the cable, the outer surface of the cable and the inner wall surface of the first end of the first threading hole 231 are kept in a bonding sealing state under the action of the resilience force of the threading plate 230, and the outer surface of the cable and the inner wall surface of the second end of the first threading hole 231 are kept in an iron and sealing state under the action of the resilience force of the threading plate 230.

Since the diameter of the first end of the first threading hole 231 is smaller than the diameter of the second end, when the cable passes through the first threading hole 231, the first end of the first threading hole 231 is elastically deformed more, and the resilience force of the first end is also larger, that is, the tightness between the cable and the first end of the first threading hole 231 is higher than the tightness between the cable and the second end of the first threading hole 231, thereby realizing double sealing of the cable by the first threading hole 231 and further improving the self protection level of the terminal 200.

In some embodiments, as shown in fig. 1-4, the distance between the first end and the upper surface of threading plate 230 is greater than the distance between the second end and the lower surface of threading plate 230.

As shown in fig. 1 to 4, since the second end of the first threading hole 231 is located below the first end of the first threading hole 231 when the installation of the electrical apparatus is completed, the distance between the first end and the upper surface of the threading plate 230 is set to be greater than the distance between the second end and the lower surface of the threading plate 230, so that the distance between the first end and the second end can be increased when the second end of the first threading hole 231 cannot be protected during the water swelling period, so that the water level can break through the first end of the first threading hole 231 into the mounting seat 220 when the water level is at a higher position, thereby further improving the protection performance of the connection terminal 200.

In some embodiments, as shown in fig. 1-4, the first threading holes 231 are a plurality of, and the plurality of first threading holes 231 are disposed at intervals.

The cable can be a single-core cable or a multi-core cable, and when the multi-core cable is electrically connected with the conductive component 210, the multi-core cable needs to be separated into separate cores and then electrically connected with the conductive component 210, so that the plurality of first threading holes 231 are applicable to the multi-core cable and the single-core cable, and the threading plates 230 with various specifications are not required to be arranged, thereby further reducing the production cost.

It should be noted that, when the conductive member 210 is used for electrical connection with the dc cable, the first threading holes 231 may be provided in two or two connection terminals 200 may be provided, and the threading plate 230 of each connection terminal 200 has one first threading hole 231.

Through the arrangement of the notch 222 and the groove 223, an installation space can be provided for the threading plate 230 on the installation seat 220, so that the whole size of the wiring terminal 200 is reduced, and the wiring terminal 200 can be suitable for a scene with a smaller space.

In some embodiments, as shown in fig. 5, threading plate 230 is an interference fit with groove 223.

Wherein, the height of the groove 223 is smaller than that of the threading plate 230, and because the threading plate 230 is made of elastic material, when the threading plate 230 is in plug-in fit with the groove 223, the threading plate 230 forms interference fit with the groove 223 in the state of elastic deformation, and the upper surface and the lower surface of the threading plate 230 are both bonded and sealed with the inner wall surface of the groove 223 under the action of the resilience force of the threading plate 230, and the interference fit between the threading plate 230 and the groove 223 can be realized by bonding or other modes.
