Description

Technical Field

[0001] The utility model relates to a knife switch, in particular to a knife switch which is convenient for wiring. Background Art

[0002] A knife switch, installed within an electrical control cabinet, is a basic electrical device primarily used for manually connecting and disconnecting circuits. Its simple and reliable structure enables circuit control, load switching, and safety protection. This switch quickly cuts power in the event of a system overload or short circuit, preventing further damage. Some models also feature status indicators, allowing operators to monitor circuit conditions.

[0003] Chinese patent document CN220585115U discloses a double-throw knife switch that does not require removal of the cover, including an insulating base, the insulating base is bolted to a protective shell at both ends, and the protective shell is provided in two groups, the front ends of the insulating base are respectively provided with wire feed slots, and the wire feed slots are distributed in an equidistant array, the upper end of the middle part of the insulating base is connected to a knife seat, and the upper end shaft of the knife seat is connected to a blade.

[0004] The above solution is installed in the electrical control cabinet by connecting the wires from one side of the knife switch and then exiting from the other side. However, the above solution has the following disadvantages: since the knife switch is usually installed on the top of the electrical control cabinet, the installation method of the knife switch in the prior art for the incoming and outgoing wires will cause great inconvenience when installed on the top side of the electrical control cabinet, resulting in installation difficulties and even installation misalignment. Utility Model Content

[0005] Aiming at the deficiencies of the prior art, the utility model provides a knife switch which is convenient for wiring.

[0006] To achieve the above-mentioned objectives, the technical solution of the present invention is as follows: a knife switch that is easy to connect, comprising a base and a protective cover, a knife switch being pivotally connected to the base, the base comprising an upper base and a lower base, the lower base and the upper base each being provided with a plurality of groups of inlet and outlet grooves, the inlet and outlet grooves being arranged on the same side; a connecting groove is further provided on the other side of the corresponding outlet groove on the upper base, the knife switch being pivotally connected to the upper base and forming an electrical connection between the connecting groove and the outlet groove.

[0007] The beneficial effects of this utility model are that its inlet and outlet troughs are arranged on the same side of the lower and upper bases, greatly simplifying the wiring work within the electrical control cabinet. This layout allows wiring personnel to conveniently perform wire entry and exit operations from the same side, improving wiring efficiency and saving space. It also reduces cable crossing, reduces the risk of short circuits, and enhances safety. During maintenance, this design also makes inspection and replacement operations more straightforward, reducing maintenance time and labor intensity. Furthermore, the neat cable layout enhances the aesthetics of the control cabinet interior, making the entire electrical system more neat and orderly.

[0008] Furthermore, the wire inlet is formed with a wire inlet at one end of the lower base, and a wire passing area is formed between the other side thereof and the lower base, and anti-slip baffles are formed at both ends of the wire passing area.

[0009] The wire routing area provides a clear path, allowing wires to transition from one side of the cable entry trough to the other in an orderly manner. This design helps maintain a clean interior of the electrical control cabinet and facilitates maintenance and repair of the wires. The provision of anti-slip baffles prevents wires from accidentally falling into other areas when passing through the wire routing area, improving installation convenience. At the same time, each wire routing area enclosed by the anti-slip baffles effectively prevents wires from falling into other wire routing areas, making identification more difficult, thereby improving wiring accuracy.

[0010] Furthermore, the wire inlet trough includes a wire inlet segment, a wire outlet segment and a guide segment connected therebetween. The guide segment is located in the middle of the wire inlet trough and causes the wire inlet segment and the wire outlet segment to be staggered.

[0011] The inclined guide section effectively prevents wires from bending or even rotating within the cable entry trough. This design allows the wires to smoothly follow the inclined guide section after exiting the trough until they enter the wire-passing area, preventing unnecessary bending or twisting within the trough. This layout not only facilitates wire installation and improves efficiency, but also helps protect the wires from damage and extend their service life. Furthermore, the inclined guide section reduces the risk of electrical failures caused by rotating or tangling wires.

[0012] Furthermore, a baffle is provided on the wire inlet trough, the baffle cover is provided on the wire inlet trough, and a wire passing hole is provided on the side of the baffle close to the wire outlet section, and the wire passing hole is protruded outside the lower base.

[0013] The baffle on the inlet trough plays a crucial role. Installed on the inlet trough, it effectively prevents wires from escaping. A wire hole is located on the side closest to the outlet, flush with the outlet trough. This layout allows wires to smoothly transition from the hole to the outlet trough without the need for additional bending or adjustment, significantly improving wiring efficiency. The baffle's wire hole protrudes from the lower base, further simplifying the wire guidance process and ensuring quick and accurate transfer of wires from the inlet to the outlet.

[0014] Furthermore, the protective cover includes a front cover, the wire inlet and wire outlet grooves are staggered on the same side of the knife switch, and a fixing hole is provided on the front cover corresponding to the wire outlet groove position, in which a fastener is inserted for fixing the front cover and the lower base.

[0015] The front cover of the protective cover features a window for viewing the outlet ducts and access holes for easily accessing the fasteners within the outlet and inlet ducts. The inlet and outlet ducts are staggered on the same side of the knife switch, significantly optimizing space utilization. Fixing holes on the front cover corresponding to the outlet ducts facilitate insertion of fasteners, quickly securing the front cover to the lower base and ensuring structural stability. This design not only reduces additional installation steps but also saves space. Furthermore, the staggered slots facilitate orderly arrangement of wires, preventing crossover and clutter.

[0020] The utility model embodiment is a knife switch which is convenient for wiring. Figure 1-4 As shown: it includes a protective cover 1 and a base 2, the protective cover 1 includes a front cover 11 and a knife cover 12, and the base 2 includes an upper base 21 and a lower base 22. The knife cover 12, the upper base 21, the lower base 22 and the front cover 11 are all connected to each other and fixed by fasteners.

[0021] The lower base 22 is provided with a plurality of wire feed slots 221. Each wire feed slot 221 is connected to both ends of the lower base 22 and has a wire passing area 222 formed between one side and the lower base. Anti-slip baffles 223 are provided at both ends of the wire passing area 222 to prevent the wires from falling out. A baffle 224 matching the shape of the wire feed slot 221 is also provided above the wire feed slot 221. The baffle 224 is provided with a wire passing hole 2241 protruding from the lower base on one side of the wire passing area 223. The wire feed slot 221 includes two wire feed sections 2211 and a wire outlet section 2213, which are arranged parallel to each other in cross section, and a guide section 2212 which is arranged at an angle to connect the two. The inclined guide section 2212 can effectively prevent the wires from bending in the wire feed slot 221.

[0022] A connection groove 211 is provided on the upper base 21 corresponding to the wire hole 2241. The connection groove 211 passes the wires to the connecting copper piece 212. A knife switch 3 is pivotally connected to the top of the connecting copper piece 212. The knife switch 3 is exposed outside the knife switch cover 12 via the knife cover 12. A wire outlet groove 213 is provided on the other side of the upper base 21 corresponding to the connection groove 211. The front cover 11 is clamped on the other side of the upper base 21 corresponding to the connection groove 211. A window 113 is provided on the front cover 11 corresponding to the wire outlet groove 213. The wire outlet groove 213 and the wire inlet groove 221 provided on the upper base 21 are offset from each other when viewed in cross section. A fixing hole 112 is provided on the front cover 11 corresponding to the wire outlet groove 213, into which a fastener is inserted for fixing the front cover 11 and the lower base 22. In addition, an operating hole 111 for operating the fasteners in the wire inlet groove 221 and the wire outlet groove 213 is provided above the position of the front cover 11 corresponding to the wire inlet groove 221 and the wire outlet groove 213 .
