Detailed Description

Embodiments of the present invention will be described in detail with reference to fig. 1 to 7.

Traction motor wire presss from both sides, including punch holder 1, lower plate 2 and bolt 3 with 1 concatenation of punch holder, a plurality of cable side by side of the concatenation formation of punch holder 1 and lower plate holds a section of thick bamboo 4 and supplies the connecting hole 5 that the bolt runs through, every cable holds a section of thick bamboo 4 and can hold a cable, bolt 3 passes connecting hole 5 and splices punch holder 1 and lower plate 2 and fasten on the motor, its characterized in that the concatenation face of punch holder 1 and lower plate 2 on all have boss 6 and can with boss 6 matched with recess 7, the boss 6 of punch holder 1 can contact the cooperation with boss 6 or recess 7 of lower plate 2.

The traction motor wire clamp comprises an upper clamping plate 1 and a lower clamping plate 2 which are spliced to form a side-by-side cable accommodating cylinder 4 and a connecting hole 5, a bolt 3 penetrates through the connecting hole to splice the upper clamping plate 1 and the lower clamping plate 2 and integrally fasten the upper clamping plate and the lower clamping plate on a motor, splicing of the upper clamping plate 1 and the lower clamping plate 2 and fixation of the cable clamp and the motor are simultaneously completed, and splicing and installation processes of the cable clamp are simplified. The splicing surfaces of the upper clamping plate 1 and the lower clamping plate 2 are provided with a boss 6 and a groove 7, the upper clamping plate 1 and the lower clamping plate 2 have two splicing modes, the first mode is that the boss 6 of the upper clamping plate 1 is in contact fit with the groove 7 of the lower clamping plate 2 as shown in figure 6, the boss 6 extends into the groove 7, and the cable accommodating barrel 4 can accommodate cables with one diameter specification; secondly, as shown in fig. 7, the boss of the upper clamping plate is in contact fit with the boss of the lower clamping plate, the cable accommodating cylinder can accommodate cables with another diameter specification, the diameter of the cable accommodating cylinder 4 formed by the second splicing mode is larger than that of the cable accommodating cylinder 4 formed by the first splicing modes, the splicing mode of the wire clamp is more flexible, the wire clamp can be used for accommodating and positioning cables with two specifications between two diameters, and the wire clamp can accommodate more types of applicable cables.

The axial direction of the connecting hole 5 is perpendicular to the axial direction of the cable accommodating cylinder 4, the connecting hole 5 is formed by splicing a step hole 11 formed in the upper clamping plate 1 and a round hole 21 formed in the lower clamping plate 2, the axial section of the step hole 11 is T-shaped, when the screw is locked conveniently, the head of the connecting hole abuts against the step surface of the step hole 11 and sinks in the step hole 11, the fastening reliability of the wire clamp and the motor is guaranteed, and the connecting hole is attractive and does not occupy space.

Wherein the connecting hole 5 is opened between the adjacent cable accommodating cylinders 4. Bolt 3 fastening is between adjacent cable holds a section of thick bamboo 4 promptly, guarantee that every cable that forms holds a section of thick bamboo 4's shape effective positioning, in-process non-deformable holding the tight cable, and when boss 6 of punch holder 1 and the boss 6 cooperation contact of lower plate 2, bolt 3 is through the position and the motor locking of two boss 6 cooperation contacts, locking power is used in two bosses 6, can guarantee that the quilt hard contact in boss 3 position presss from both sides tightly, thereby make punch holder 1 and lower plate 2 by effective concatenation.

Wherein, boss 6 and recess 7 set up respectively between adjacent cable holding cylinder 4, only set up a boss 6 or recess 7 between adjacent cable holding cylinder 4, and boss 6 and recess 7 all distribute and the quantity is the same on punch holder 1 and lower plate 2 in turn. The upper clamping plate 1 and the lower clamping plate 2 can be conveniently spliced in two ways, the first way is that a boss on the upper clamping plate 1 is in contact fit with a groove on the lower clamping plate 2, and a groove on the upper clamping plate 1 is in contact fit with a boss on the lower clamping plate 2, as shown in fig. 6; the second is that the boss on the upper clamping plate 1 is contacted and matched with the boss on the lower clamping plate 2, and the groove on the upper clamping plate 1 is opposite to but not contacted with the groove on the lower clamping plate 2, as shown in fig. 7.
