Problems solved by technology
[0004] 1) One bolt is used for series locking. When the bus bar copper bar is deformed or the thickness dimension is deviated, it will easily lead to uneven clamping force, resulting in insufficient contact area between the conductive plate and the bus bar copper bar, and increased contact resistance. , prone to fever
[0005] 2) Since the busbar copper bars are located on both sides of the bolts, holes need to be opened on the conductive plate, so not only the structure is relatively loose and bulky, the copper consumption of the conductive plate is large, the cost is high, and the effective contact area of the conductive plate is also reduced
[0006] 3) The conductive plate is fixed on the surface of the insulating partition by adhesion without positioning, so if there is an external force after heating, it may be displaced, resulting in a decrease in the area of the overlap with the busbar copper bar and an increase in contact resistance
[0007] 4) There is no limit and guidance for the busbar copper bars on both sides of the connector, so not only is it difficult to install, but also the busbar copper bars are prone to shake under the action of external force, posing a safety hazard
[0008] 5) The connecting bolts are directly exposed on the surface of the splint, so it can be disassembled and stolen with a simple tool such as a common wrench, and the anti-theft security is poor

Embodiment Construction
[0032] Before further explaining the structure of the present invention, it is necessary to make a brief description of the structure of the busway matching the present invention as follows:
[0033] like Figure 10 As shown: the busway is composed of the busbar copper bar 8 located in the wireway 7, the protective cover 12 which is in an inverted "U" shape and is respectively fixed at both ends of the wireway 7 and tightens the busbar copper bar 8; There is respectively a reinforcing rib 13 curled into a C shape on both sides.
[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0035] like Figure 1-9 As shown: the present invention includes a connector located between the two sections of the wire groove 7, and the connector is composed of a clamping body located between two clamping plates 1 and pressed by the two clamping plates 1.
[0036] The clamping body is composed of four insulatin...

The invention discloses a bus duct anti-theft connector, and belongs to a power transmission and distribution device. The invention aims to provide an anti-theft electric connector with reliable copper bar connection, and the connector is composed of two clamping plates and a clamping body; and the clamping body is composed of multiple insulating partitions with conductive plates fixed on the surface and an insulating side plate. The surfaces of the insulating partition plates are arranged in parallel towards the back face of the insulating side plate. A blocking strip (9-4) is arranged in a T-shaped groove (9-2) of the insulating partition plate (9), a guide strip (9-1) and a positioning strip (9-3) are arranged on the surface of the insulating partition plate (9), a first guide groove (9-6) and a first positioning groove (9-5) are formed in the back surface, and a second guide groove (5-1) and a second positioning groove (5-2); and the clamping plate (1), the insulating side plate (5) and the insulating partition plate (9) are clamped by two bolts (10), the back surface of the clamping plate (1) is provided with a limiting groove for accommodating a nut and a bolt head, the limiting groove is covered by the groove cover (4), and the end head of the groove cover (4) is covered by the cover plate (6).
Description
technical field [0001] The invention relates to an electrical connector, in particular to a bus duct connector, belonging to power transmission and distribution devices. Background technique [0002] Due to the advantages of compact structure, convenient use, and large carrying capacity, busway is widely used in power transmission and distribution systems of large commercial plazas, real estate buildings, and hospitals. [0003] During the wiring construction process, each section of bus duct needs to be connected through electrical connectors. At present, the widely used electrical connector usually consists of an insulating side plate between two splints, a plurality of insulating partitions fixed with conductive plates, and bolts that connect and lock the splint, insulating side plates and insulating partitions. ; Such as "CN208256929U", "CN210111545U" and so on. Although these connectors are relatively simple, they generally have the following defects: [0004] 1) One...
