Embodiment
In order to there be understanding clearly to technical characteristic of the present utility model, object and effect, now contrast accompanying drawing and embodiment of the present utility model is described.
As shown in Figure 1, Figure 2, Figure 3 shows, the mechanical connector 100 that the utility model provides, comprise open mouth tongs 1, open mouth tongs 1 are articulated with in a clamping frame structure 3 by connecting axle 2, a wire linkage unit 4 is provided with outside the clamping part 11 of open mouth tongs 1, in the present embodiment, wire linkage unit 4 is a connecting screw rod, and interim lead wire 9 is tightened by connecting screw rod and is resisted against outside clamping part 11.Inside the tong arm portion 12 of open mouth tongs, free end is resisted against one end of a screw rod 5, screw rod 5 is threaded connection in clamping frame structure 3, the other end of screw rod 5 is provided with a junction 51, in the present embodiment, connecting portion 51 is a clamping pin structure, insulating bar (prior art, not shown) can be releasably connected on screw rod 5 by this clamping pin structure, screw rod rotation process during to complete high-altitude air line working.For ensureing good conductivity, the clamping part 11 of open mouth tongs 1 in mechanical connector 100, is had at least to adopt fine aluminum alloy (or other electric conductivities good metal material) material processing and fabricating.Use mechanical connector 100 carry out interim lead wire 9 set up time, the clamping part 11 of open mouth tongs 1 is clamped in by the end connecing wire 8, one end of interim lead wire 9 is connected to outside clamping part 11 by wire linkage unit 4, is connect wire 8, interim lead wire 9 realizes electrical connection by mechanical connector 100.
Further, as shown in Figure 1 and Figure 2, clamping frame structure 3 comprises on the first clamping frame 31, first clamping frame 31 can be connected with the second clamping frame 32 rotationally, and open mouth tongs 1 are articulated with on the first clamping frame 31, and screw rod 5 is threaded connection in the second clamping frame 32.In the present embodiment, first clamping frame 31 and the second clamping frame 32 are U-shaped structure, first clamping frame 31 is relative with the second clamping frame 32 opening forms spatial accommodation, the tong arm portion 12 of open mouth tongs and the top of screw rod 5 is accommodated in this spatial accommodation, as shown in Figure 2, screw rod 5 can be followed the second clamping frame 32 and be rotated relative to the first clamping frame 31, and and in different angles between tong arm portion 12 axis of open mouth tongs.First clamping frame 31 connects by being connected pivot pin 33 with the side of the second clamping frame 32, and the first clamping frame 31 is connected by tighten the screws 34 with the opposite side of the second clamping frame 32, connects pivot pin 33 and coaxially arranges with tighten the screws 34; When unclamping tighten the screws 34, can mutually rotate between first clamping frame 31 and the second clamping frame 32, when angle adjustment is to fit value between the first clamping frame 31 and the second clamping frame 32, rotate tighten the screws 34 to tightening state, relatively fixing between the first clamping frame 31 and the second clamping frame 32.
As shown in Figure 1, Figure 3, in the present embodiment, the clamping part 11 of open mouth tongs 1 comprises the wire linkage unit 4 described in arranged outside of symmetrically arranged first clamping limb 111 and the second clamping limb 112, first clamping limb 111.First clamping limb 111 and the second clamping limb 112 are articulated with in clamping frame structure 3 respectively by connecting axle described in one 2 near the one end in described tong arm portion 12.More firm in order to clamp, general first clamping limb 111 and the second clamping limb 112 are all formed with semi-circular clamp mouth 114, two semi-circular clamp mouth 114 openings and are oppositely arranged, be formed with circular clamp space, and connect the cross-sections match of wire 8.Be connected with a spring 113 between first clamping limb 111 and the second clamping limb 112, spring 113 is positioned at the side of semi-circular clamp mouth 114 near connecting axle 2.In order to improve the skid resistance of clamping part 11, inside semi-circular clamp mouth 114, be provided with zigzag structure 1141.When the clamping part 11 opening range demand of open mouth tongs 1 is smaller (mechanical connector now also can be described as little jaw mechanical connector), as shown in Figure 3, the distance between the grasping part formed between the first clamping limb 111 and the second clamping limb 112 and connecting axle 2 is less; When open mouth tongs 1 clamping part 11 opening range demand is larger (mechanical connector now also can be described as mouth of tongs mechanical connector), as shown in Figure 1, the distance between the grasping part formed between the first clamping limb 111 and the second clamping limb 112 and connecting axle 2 is larger.
Further, as shown in Figure 1, Figure 3, the tong arm portion 12 of open mouth tongs 1 comprises symmetrically arranged first tong arm 121 and the second tong arm 122, first tong arm 121 and the first clamping limb 111 are formed in one component, second tong arm 122 and the second clamping limb 112 are formed in one component, first tong arm 121 is provided with hemisphere jut portion 123 with the free end of the second relative side of tong arm 122, one end of hemisphere jut portion 123 and screw rod 5 against.One end that inside screw rod 5 and tong arm portion 12, two hemisphere jut portions 123 of free end lean is the vertex of a cone structure 52 diametrically go up convergent, and this vertex of a cone structure 52 effectively can control the folding of tong arm portion 12 free end, and then the folding controlling clamping part 11 clamps; Pivot center between first clamping frame 31 and the second clamping frame 32 is that spatial vertical is crossing with the axis of screw rod 5, vertex of a cone structure 52 overlaps with the pivot center between the first clamping frame 31 and the second clamping frame 32 against the line between point with two hemisphere jut portions 123, meet the second clamping frame 32 when the first clamping frame 31 rotates, still have good contact with tong arm portion 12 free end.
As shown in Figure 4, when the mechanical connector 100 using the utility model to provide carries out live wire connection, generally can use in pairs.First according to on-the-spot two by the angle connect between angle adjustment first clamping frame 31 of wire 8 and the second clamping frame 32, with the clamp port meeting the clamping part 11 of open mouth tongs 1 with to be connect wire 8 just in time relative, convenient operation.Then the two ends of interim lead wire 9 are fixed on two mechanical connectors 100 respectively by wire linkage unit 4, two mechanical connectors 100 respectively by screw rod 5 end connecting portion 51 connect an insulating bar.Being clamped in by mechanical connector 100 by insulating bar is connect on wire 8, is unloaded by insulating bar after clamping from screw rod 5, two by connect wire 8 by two mechanical connectors 100 and between interim lead wire 9 realize electrical connection.Generally for the rigidity increasing interim lead wire 9, usually a sheathed hollow insulated tube 71 on interim lead wire 9, come off to prevent interim lead wire 9, connect an insulation auxiliary catch 72 respectively at the two ends of hollow insulated tube 71, operating personnel uses insulating bar to be hung on adjacent wires or other structural members by insulation auxiliary catch 72.
From the above mentioned, the mechanical connector that the utility model provides, realizes by the electrical connection connect between wire, interim lead wire by the open mouth tongs that the opening with conducting function is adjustable; By can the vertex of a cone respective outer side edges of clamping frame structure and screw rod in relative rotation, the wire realized in polarizers of big angle scope connects, applied widely; One end of screw rod firmly can be connected with insulating bar, is realized the clamping of high-altitude stringing by insulating bar, and simple to operate, fail safe is high.
The foregoing is only the schematic embodiment of the utility model, and be not used to limit scope of the present utility model.Any those skilled in the art, equivalent variations done under the prerequisite not departing from design of the present utility model and principle and amendment, all should belong to the scope of the utility model protection.
