Abstract
The utility model discloses a hole-free copper bar connector comprising a screw rod and a connecting rod. The connecting rod comprises two annular rings arranged up and down and a connecting arm through which the two annular rings are connected. The annular ring at the top is sleeved on the screw rod. A thread bushing is sleeved on the bottom of the screw rod. The bottom of thread bushing is equipped with a first meshing tooth plane. A second meshing tooth plane in cooperation with the first meshing tooth plane is disposed over the annular ring at the bottom. The copper bar connector eliminates a hole and has characteristics of fast connection, wide adaptability, and wide application.
Description
Technical field
The utility model relates to a kind of connector, particularly relates to a kind of copper bar connector of exempting to punch.
Background technology
Existing copper bar interconnection technique is single, mainly is to wear screw after the punching to connect, and it is as follows to have problems:
1. behind the punching overlap joint, the hole misaligns, and screw is not locked, and also causes the copper bar distortion even lock, and requires copper bar to be processed with higher precision;
2. the overlap joint area increases contact resistance owing to diminish after the punching, causes screw junction heat accumulation, and potential safety hazard is arranged;
3. at different overlap joint areas, need the different screw diameter of design and position and the number of punching, increase processed complex degree and assembly difficulty;
4. can not solve the existence dislocation of copper bar overlap joint back and tilt problem that rigging error is brought;
5. can not the flush joint butt joint.
Summary of the invention
At the deficiencies in the prior art, the purpose of this utility model is, a kind of bronze medal connector of exempting to punch is provided, to guarantee that copper bar reliably overlaps.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the copper bar connector of exempting to punch, it is characterized in that: comprise screw rod and connecting rod, described connecting rod comprises two annular rings that are arranged above and below and the linking arm that is connected two annular rings, the annular ring of wherein being located at top is enclosed within on the screw rod, the lower end of described screw rod is with thread bush, the bottom of described thread bush is provided with the first grinding tooth plane, and the top of being located at the annular ring of bottom is provided with the second grinding tooth plane of matching with the first grinding tooth plane.
The aforesaid copper bar connector of exempting to punch is characterized in that: be provided with stop nut between the described annular ring of being located at top and the thread bush.
The aforesaid copper bar connector of exempting to punch is characterized in that: be provided with the screw thread that matches with screw thread on the described screw rod in the described thread bush.
The aforesaid copper bar connector of exempting to punch is characterized in that: being shaped as of described linking arm "] " type.
The utility model beneficial effect is: adopt and exempt from perforating type spiral compressing structure, utilize the downward pressure of rotation generation of screw rod to be delivered to the first grinding tooth plane, suiting into, copper bar guarantees that copper bar does not get loose, simultaneously because the screw thread at connecting rod place makes rises on the second grinding tooth plane, also suit into copper bar surface, both have guaranteed the positive pressure of copper bar, reach the purpose of super-high-current; Being suitable for different width copper bars, is a modulus with 20 width, is combined into the adjustable structure in a plurality of installation sites.The utility model is exempted from punching, connection fast, adaptation is wide, application is wide.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
For further disclosing the technical solution of the utility model, now be described with reference to the accompanying drawings execution mode of the present utility model: as shown in Figure 1, the copper bar connector of exempting to punch, comprise screw rod 1 and connecting rod, described connecting rod comprises two annular rings 2 that are arranged above and below and the linking arm 3 that is connected two annular rings 2, being shaped as of described linking arm 3 "] " type.
The annular ring 2 of wherein being located at top is enclosed within on the screw rod 1, and the lower end of described screw rod 1 is with thread bush 4, is provided with the screw thread that matches with screw thread on the described screw rod 1 in the described thread bush 4.Be located between the annular ring 2 on top and the thread bush 4 and be provided with stop nut 5, prevent that the pressure of copper bar faying surface from discharging.
The bottom of described thread bush 4 is provided with the first grinding tooth plane 6, and the top of being located at the annular ring 2 of bottom is provided with the second grinding tooth plane 7 of matching with the first grinding tooth plane 6.
Operation principle: during use copper bar is placed between the first grinding tooth plane 6 and the second grinding tooth plane 7, utilize the downward pressure of rotation generation of screw rod 1 to be delivered to the first grinding tooth plane 6, suiting into, copper bar guarantees that copper bar does not get loose, because the screw thread at connecting rod place makes the second grinding tooth plane 7 rise, also suit into copper bar surface simultaneously, both have guaranteed the positive pressure of copper bar, reach the purpose of super-high-current, final rotation stop nut 5 prevents that the pressure of copper bar faying surface from discharging, and reaches purpose of design.
More than by description of listed embodiment, basic design of the present utility model and basic principle have been set forth.But the utility model never is limited to above-mentioned listed execution mode, and every equivalent variations, improvement and deliberately of inferior quality behavior of doing based on the technical solution of the utility model of change all should belong to protection range of the present utility model.
Claims (4)
