The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.

Figure 1 shows an exploded view of an insulated spacer 100 in an embodiment of the present invention. Referring to fig. 1, an insulated spacer 100 includes a spacer body 130 and at least one pair of wire clamp contacts 110, 120; a pair of wire clamping connectors 110,120 are respectively mounted at both ends of the spacer body 130. Fig. 2 shows a schematic diagram of a wire clip connector 200 according to an embodiment of the present invention. Referring to fig. 2, each wire clamp connector 200 includes: a card connector body 210 and an elastic part 220; the card connector body 210 is provided with an inlet notch 2101 and the elastic part 220 forms a wire guide 230 with the card connector body 210.

The insulating spacer in the prior art generally needs to be installed while a line is erected, for example, a lifting device lifts an installer to the same height as a power transmission line for installation; or the installer climbs the pole for installation. But to the topography that lifting equipment can not in time provide or be unsuitable lifting equipment operation, installer can't install current insulating conductor spacer basically, even if install through the mode of climbing the pole, the quantity that can install is also limited. And the aging of the electric pole in partial areas is not suitable for pole climbing operation.

In the installation process of the insulating spacer in the above embodiment, an installer can operate the card connector body 210 to make the wires enter the wire guide 230 through the wire inlet notch 2101 provided in the card connector body 210.

In some embodiments, referring to fig. 2, the resilient portion 220 includes a first resilient portion 2201 and a second resilient portion 2202 in close proximity to each other. In some embodiments, the first elastic portion 2201 and the second elastic portion 2202 that are adjacent to each other may be understood as the first elastic portion 2201 and the second elastic portion 2202 being elastically abutted. In other embodiments, the first elastic portion 2201 and the second elastic portion 2202 approaching each other may be understood as the first elastic portion 2201 and the second elastic portion 2202 approaching each other, and a gap is formed between the first elastic portion 2201 and the second elastic portion 2202. It should be appreciated that, due to the need to restrain the wire within the wire guide 230, the gap between the first resilient portion 2201 and the second resilient portion 2202 is smaller than the outer diameter of the wire to avoid the wire from sliding out of the wire guide 230. During the installation of the insulating spacer, the wires enter the wire clamping head 200 and then press and separate the first elastic part 2201 and the second elastic part 2202, which are close to each other, to enter the wire hole 230. After the wire enters the wire guide 230, the first elastic portion 2201 and the second elastic portion 2202 are restored to a state of being close to each other again to restrain the wire in the wire guide 230.

In some embodiments, referring to fig. 1, the spacer body 130 includes an insulating rod 1301 and a plurality of insulators 1302, the plurality of insulators 1302 being disposed on the insulating rod 1301.

Figure 3 shows a schematic view of the mounting of an insulated spacer 300 according to an embodiment of the utility model. In some embodiments, as shown in fig. 3, the insulating spacer 300 is used to laterally isolate the wires (e.g., wires 330 and 340 shown in fig. 3), so that the length of the spacer body 350 matches the lateral spacing of adjacent wires. The length of the spacer body 350 may be, for example, 45 cm to 55 cm.

In some embodiments, the inlet slot may be understood as an opening of the card connector body. For example, the joint body is U type structure, and the inlet wire notch can be U type structure breach.

In some embodiments, the resilient portion may be understood as an elastically deformable part. For example, the elastic portion may include a spring. In some embodiments, the resilient portion may also comprise a component made of a rubber material. In other embodiments, the resilient portion comprises a spring clip. In some embodiments, the spring clip includes a first resilient tab and a second resilient tab, the outer sides of the first and second resilient tabs abutting each other.

In some embodiments, the first and second elastic portions 2201, 2202 as shown in fig. 2 may be first and second elastic panels, respectively. The outer side surfaces of the tail ends of the first elastic sheet and the second elastic sheet are of cambered surface structures. The wire holes are formed in the two cambered surface structures and the inner side of the clamping head body, so that the peripheral sides of the wires can be limited between the two cambered surface structures and the inner side of the clamping head body. In some embodiments, a first end of the card connector body opposite to the wire inlet notch is an arc-shaped structure, and the arc-shaped structures of the outer side surfaces of the tail ends of the first elastic sheet and the second elastic sheet and the arc-shaped structure of the first end of the card connector body can have substantially the same curvature. In other embodiments, the arc structures of the outer side surfaces of the tail ends of the first elastic sheet and the second elastic sheet and the arc structure of the first end of the clamping head body can have different curvatures.

In some embodiments, the first elastic sheet or the second elastic sheet may be an elastic sheet having an arc-shaped main body. The arc-shaped structure main bodies of the first elastic sheet and the second elastic sheet are close to each other. In some embodiments, a wire guide region (e.g., triangular region 2102 shown in fig. 2) is formed between the first and second resilient sheets. For example, the arc tops of the arc-shaped structural main bodies of the first elastic piece and the second elastic piece are close to each other, and the ends, close to the wire inlet notch, of the arc-shaped structural main bodies of the first elastic piece and the second elastic piece are gradually far away from the wire guide area. In the process of installing the insulating spacer, the wire enters the wire guide area after passing through the wire inlet notch, and the wire is limited in the wire guide area and moves towards the mutual approaching part of the first elastic sheet and the second elastic sheet so as to extrude and separate the first elastic sheet and the second elastic sheet which approach each other so as to enter the wire hole.

In some embodiments, the elastic parts which are close to each other and the inner side of the clamping head body have deformation spaces. In some embodiments, the deformation space may be a compression space when the elastic portion is compressed, or a space for a part of the structure to move when the elastic portion is compressed. For example, the deformation space may be a space between the arc-shaped structural bodies of the first elastic sheet and the second elastic sheet and the clamping head body. When the insulating spacer is installed, the wire extrudes and separates the first elastic sheet and the second elastic sheet which are close to each other, and the first elastic sheet or the second elastic sheet moves in the deformation space. It should be understood that the first elastic piece and the second elastic piece can move simultaneously, or only one of the first elastic piece and the second elastic piece can move, as long as the lead can enter the lead hole.

In some embodiments, referring to fig. 1, the insulated spacer 100 further includes adapters 140,150 for connecting the wire trap contacts 110,120 to the spacer body 130. In some embodiments, the adapter may include, but is not limited to, a right angle adapter. In some embodiments, the first end of the adapter is sleeved on one end of the spacer body, and the second end of the adapter is sleeved on the extending end on one side of the inlet slot. For example, the adapter is the right angle adapter of tubular structure, and the one end setting of conductor spacer body is in the tubular structure on the first right angle limit of right angle adapter, and the extension end of inlet wire notch one side sets up in the tubular structure on the second right angle limit of right angle adapter.

In some embodiments, the insulating spacer further includes mounting bar attachment portions (e.g., mounting bar attachment portions 160,170 shown in FIG. 1, or mounting bar attachment portion 240 shown in FIG. 2) disposed on the outside of the card connector body. When the insulating spacer is installed, an installer is connected with the connecting part of the installation rod through the installation rod on the ground to operate the insulating spacer. The mounting lever connection portion may have a polygonal structure such as a triangular structure or a square structure provided outside the card connector body, or may have a ring structure (e.g., the mounting lever connection portion 240 shown in fig. 2). In some embodiments, one or more mounting bar connections may be provided on the outside of each card connector body. In some embodiments, mounting bar connections may be provided in multiple directions outside each of the bayonet body. In some embodiments, the mounting post coupling portion is rotatably coupled to the bayonet body such that the mounting post coupling portion can be rotatably adjusted to an orientation suitable for coupling with a mounting post (e.g., the mounting post coupling portions 160,170 shown in FIG. 1 have different orientations, and the mounting post coupling portion 160 and the mounting post coupling portion 170 being perpendicular to each other can be adapted to couple with mounting posts in different orientations).

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the utility model has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
