In addition, the wire clamp of this embodiment is also required to be in conductive communication with the overhead wire, and therefore, a clamping mechanism 200 fixedly connected to the overhead wire a is further provided at the rear end of the conductive main shaft 100. The clamping mechanism 200 includes a base 210 and an upper cover 220, and a clamping opening 230 is formed in front of the upper cover 220 and the base 210. Generally, the clamping mechanism 200 and the conductive spindle 100 are tightly fitted together, so as to ensure reliable electrical conduction therebetween. When the cable is used, the upper cover 220 and the base 210 are loosened, so that the clamping port 230 is in an open state, then the overhead cable needing to be conductive is peeled, the exposed wire core is placed into the clamping port 230, and then the upper cover 220 is screwed, so that the wire core is tightly clamped on the clamping port 230. Thus, power is transferred through the conductive main shaft 100 to the clamping mechanism 200 and then to the overhead cable. Therefore, it can be understood that the clamping mechanism 200 is mainly made of a conductive material, or at least the contact portion of the clamping mechanism 200 with the conductive spindle 200 and the wire core is ensured to be the conductive material, and the conductive material of the contact portion is communicated.

Next, the specific structure of the clamping mechanism 200 in the present embodiment will be discussed in detail.

The base 210 is a metal casting. Referring to fig. 1 to 3, the base 210 includes a base portion 211 and a first clamping portion 212, and the base portion 211 and the first clamping portion 212 are integrally formed. The base part 211 comprises a circular base, an annular surrounding wall is arranged above the base, the surrounding wall is not a complete circle, the first wire clamping part 212 is arranged beside the surrounding wall, and the first wire clamping part 212 comprises an arc-shaped bearing opening 231 with an upward opening.

Referring to fig. 1, 2 and 4, the upper cover 220 is also a metal casting.

Meanwhile, since the mounting portion 221 is sleeved on the base portion 211, the upper cover 220 can be connected with the base 210 in a vertically sliding manner, and when the upper cover 220 and the base 210 slide away from each other, the inner diameter of the clamping opening 230 is increased; in contrast, when the upper cover 220 and the base 210 slide relatively close to each other, the inner diameter of the clamping opening 230 becomes smaller. When the cable core clamping device is used, the inner diameter of the clamping opening 230 needs to be smaller than the outer diameter of the cable core, so that the stroke of the upper cover 220 and the radiuses of the bearing opening 231 and the pressing opening 232 need to be designed according to the outer diameter of the cable core to be clamped.

The following discusses how the conductive spindle 100 is fixedly coupled to the clamping mechanism 200.

The conductive spindle 100 may be a solid metal bar, a connector 110 is disposed at a lower end of the conductive spindle 100, and a mounting post 120 connected to the clamping mechanism 200 is disposed at an upper end of the conductive spindle 100. A positioning step 130 is provided between the connection head 110 and the mounting post 120. In this embodiment, the outer diameter of the mounting post 120 is smaller than the outer diameter of the connecting head 110. When installed, the mounting posts 120 all penetrate the base 210 and the top cover 220. The shape of the mounting post 120 may be circular or polygonal (e.g., hexagonal, etc.), and in this embodiment, the mounting post 120 is circular.

Be equipped with first mounting hole on base 210's the basic part 211, the lower extreme of first mounting hole can set up the chamfer to make the cooperation of erection column 120 and base 210 inseparabler, and be equipped with the second mounting hole on the installation department 221 of upper cover 220, the second mounting hole is foretell through-hole 223 promptly. A threaded section 140 may be provided at a portion of the mounting post 120 penetrating through the upper cap 220, a compression nut 300 is in threaded connection with the threaded section 140, and a lower end surface of the compression nut 300 abuts against an upper surface of the upper cap 220.

After the installation, because the base 210 and the upper cover 220 are sleeved on the installation column 120, the upper cover 220 can be connected to the base 210 in a sliding manner up and down along the installation column 120. When the compression nut 300 is screwed down, the upper cover 220 is pressed and relatively moved downward, thereby clamping the wire core in the clamping opening 230.

In order to ensure reliable electrical connection between the conductive spindle 100 and the clamping mechanism 200, the mounting post 120 and the two mounting holes are preferably in interference fit, but if the mounting post 120 and the mounting hole are in interference fit, the upper cover 220 is worn when sliding up and down, and the resistance to sliding up and down is large, which makes the operation laborious.

Therefore, as a further preferred embodiment, an installation groove 224 is added to the through hole 223, the installation groove 224 is a circular groove with a ring shape, the installation groove 224 may be located in the middle of the through hole 223, and the inner diameter of the installation groove 224 is larger than the inner diameter of the through hole 223. A watch band finger 400 is nested in the mounting groove 224. The strap fingers 400 may be a conductive product manufactured by Stadobil, and the strap fingers 400 (MULTILAM flex ML-CUX) are two-component twisted blade fingers, are of a "stretchable" design, and are compact and flexible. The multi-layer flat plate type multi-layer flat plate capacitor has the same characteristics as all multi-layer flat plate capacitor products, high performance and low loss, adopts precise and ingenious structural design, and has excellent and constant current carrying capacity, extremely small contact resistance, reliability and durability.

Because the watchband contact finger 400 is additionally arranged in the through hole 223, the inner side surface of the contact finger 400 is closely matched and connected with the mounting column 120, so that a clearance fit mode can be adopted between the through hole 223 and the mounting column 120, and the upper cover 220 can slide up and down more smoothly.

Similarly, in order to improve the conductivity between the clamping opening 230 and the core, the band contact finger 400 may be added to the clamping opening 230. For example, referring to fig. 3, two recesses are also formed in the support base 231, in which the band fingers 400 are likewise inserted.

Like this, through all set up watchband contact finger 400 between electrically conductive main shaft 100 and clamping mechanism 200, between clamping mechanism 200 and the sinle silk, can make this fastener possess better electric conductive property, the range of application of product is wider.

Of course, in this embodiment, the mounting post 120 and the upper cover 220 are fastened by the compression nut 300 as a locking unit, and in some other embodiments, other locking units commonly used in the art may be used for connection. For example by a compression spring or the like.

In addition, in order to protect the conductive main shaft 100, the conductive main shaft is more stable and reliable in use. The protective shell 500 is added outside the conductive spindle 100 in this embodiment, the protective shell 500 mainly covers the connector 110 of the conductive spindle 100, and can be protected when the connector 110 is connected with the conductive female socket. Meanwhile, the conductive female socket is also conveniently mounted through the guiding effect of the inner wall of the protective shell 500.

Referring to fig. 1 and 2, the protective casing 500 is integrally in a cartridge, and the protective casing 500 is made of an insulating material (e.g., PA). The length of the protective shell 500 is greater than that of the connecting head 110, and the upper end of the protective shell 500 is close to the positioning step 130, that is, the upper end of the protective shell 500 can abut against the lower end of the base 210, so that the product consistency of the cable clamp is better. And, at the lower end of the protective case 500, an opening for inserting the conductive female socket is provided. In addition, in order to protect the conductive main shaft 100, a waterproof plug 510 may be added at the opening, the waterproof plug 510 is in a cover shape, the waterproof plug is generally made of a waterproof soft material, and when the conductive main shaft is not used, the opening of the protective shell 500 is blocked by covering the waterproof plug 510. Also, to prevent the waterproof plug 510 from being lost when removed, the waterproof plug 510 further includes a mounting ring that is nested on the outer circumference of the protective case 500. When the waterproof plug 510 is removed, the waterproof plug 510 may be attached to the protective case 500.

Further, in order to facilitate the installation of the protective shell 500 and the conductive spindle 100, an installation structure 520 is further disposed at the upper end of the protective shell 500. The upper end of the protective shell 500 comprises an outer wall, the mounting structure 520 comprises a sleeve hole formed in the upper end face of the protective shell 500, a plurality of clamping claws 521 are arranged around the sleeve hole, the upper ends of the clamping claws 521 are fixedly connected with the protective shell 500, the lower ends of the clamping claws 521 are suspended, and clamping grooves are formed in the periphery of the conductive main shaft 100 and correspond to the clamping claws 521.

The outer side of the claw 521 is a clamping wall 522, a cavity 530 is left between the clamping wall 522 and the outer wall, and the cavity 530 is a substantially annular cavity. A wedge-shaped locking block 540 is disposed in the cavity. In this embodiment, the locking block 540 is also an annular block, and the cross-sectional view of the locking block 540 is a wedge shape with a small top and a large bottom.

When the conductive spindle 100 is installed, the locking block 540 is placed in the cavity 530, the conductive spindle 100 is inserted into the protective shell 500, when the conductive spindle 100 passes through the claw 521, an outward pressing force is generated on the claw 521, and due to the existence of the locking block 540, the claw 521 receives an inward pressing force, so that when the conductive spindle 100 is installed in place, the claw 521 is tightly attached to the clamping groove, and the protective shell 500 is tightly connected with the conductive spindle 100.

Further, in order to make the protective housing 500 and the conductive spindle 100 more tightly connected, the upper end of the locking block 540 may be slightly higher than the protective housing 500, because the base 210 will abut against the protective housing 500 when the cable clamp is assembled, and the locking block 540 is forced to move downwards by the downward pressure of the base 210, so that the connection between the clamping jaws 521 and the clamping groove is tighter, and the conductive spindle 100 is firmly limited on the protective housing 500.

While the preferred embodiments of the present invention have been described, the present invention is not limited to the above-described embodiments, and those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and such equivalent modifications or substitutions are to be included within the scope of the present invention defined by the claims.
