DETAILED DESCRIPTION OF THE INVENTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 5 , a four-hole wire groove wiring adapter device of the present utility model includes an upper pressing plate 1 and a lower pressing plate 2. The upper pressing plate 1 and the lower pressing plate 2 are arranged parallel to each other in the vertical direction. A plurality of copper sheets 12 are provided between the upper pressing plate 1 and the lower pressing plate 2. Four channels 5 are provided between the upper pressing plate 1 and the lower pressing plate 2. Taking two adjacent channels 5 as a group among the four channels 5, the two groups are based on the vertical center line of the upper pressing plate 1 or the lower pressing plate 2 on the upper pressing plate 1 and are symmetrically arranged about the upper pressing plate 1 or the lower pressing plate 2. A cross screw 8 can be detachably connected in each of the channels 5. When in use, a four-hole wire groove wiring adapter device is used to replace the traditional single-hole wire groove wiring adapter device. There is no need to punch and connect each copper sheet 12 one by one. Only need to stack the copper sheets 12 in sequence between the upper pressing plate 1 and the lower pressing plate 2, and clamp each copper sheet 12 by the upper pressing plate 1 and the lower pressing plate 2 through uniformly applying force to thread each cross screw 8, so that each copper sheet 12 can maintain electrical conductivity stability when connecting electrical components, avoid poor contact, and can be used for a long time.

[0022] Furthermore, a upper groove rail 4 is provided at the center of the top of the upper pressing plate 1. Through the upper groove rail 4, the four-hole wire groove wiring adapter device can be installed in the track structure of the engineering workshop, which is convenient for the installation of the upper pressing plate 1 on one side and has assembly versatility. Upper positioning grooves 3 are provided on both the left and right sides of the top of the upper pressing plate 1. The upper ends of the channels 5 are opened inside the upper positioning grooves 3, which is convenient for positioning the opening positions of the channels 5, facilitating the replacement of parts, and can save resources.

[0023] A lower groove rail 7 is provided at the center of the bottom of the lower pressing plate 2. Through the lower groove rail 7, the four-hole wire groove wiring adapter device can be installed in the track structure of the engineering workshop, which is convenient for the installation of the lower pressing plate 2 on the other side and has assembly versatility. Lower positioning grooves 6 are provided on both the left and right sides of the bottom of the lower pressing plate 2. The lower ends of the channels 5 are opened inside the lower positioning grooves 6, which is convenient for positioning the opening positions of the channels 5, facilitating the replacement of parts, and can save resources.

[0024] A first gasket 10 is provided between the cross screw 8 and the upper extrusion plate 1. When the contact area between the cross screw 8 and the upper extrusion plate 1 is small, the acting force will also be correspondingly small, resulting in easy loosening. To ensure a more secure connection between the cross screw 8 and the upper extrusion plate 1, the contact area between the two is increased through the first gasket 10. This not only improves the connection stability but also reduces the pressure on the contact surface, thereby reducing the damage to the cross screw 8 and extending the service life of the cross screw 8. A fastening nut 9 is also connected to the lower end of the cross screw 8 that sequentially passes through the upper extrusion plate 1 and the lower extrusion plate 2. A second gasket 11 is provided between the fastening nut 9 and the lower extrusion plate 2. The first gasket 10 and the second gasket 11 can be spring washers, bolt bevel washers, or bolt square washers. The first gasket 10 and the second gasket 11 play a role in preventing loosening. When the mechanical equipment related to wiring operates, due to various vibrations or oscillations, the joints between the cross screw 8, the upper extrusion plate 1, and the lower extrusion plate 2 are prone to loosening. They can effectively prevent the loosening of these joints under dynamic conditions. They maintain the stability and safety of the connecting parts by increasing friction or providing additional support, especially in high-load and vibrating environments.

[0025] The four-hole type wire groove wiring adapter device provided in this case uses four groups of screws to position the stacking positions of several copper sheets, so as to press each copper sheet tightly, making the force on the four-corner connection wires uniform, the operation stable, and avoiding the situation of poor contact between the copper sheet and the connecting wire. In addition, each copper sheet does not need to be punched, saving manpower and material resources and effectively improving the operation efficiency.

The special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art.

Coupled with the circuit connection adopting the conventional connection method in the prior art, details are not described here. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0027] In addition, it should be understood that although this specification is described according to the embodiments, not each embodiment only contains an independent technical solution. The narrative way of this specification is only for clarity. Those skilled in the art should regard the specification as a whole.
