Description

Technical Field

[0001] This utility model relates to the technical field of current-carrying components, specifically to a current-carrying component. Background Technology

[0002] In the industrial era, the current requirements for current-carrying components varied across two stages, either decreasing or increasing. Higher currents placed stringent demands on the reliability of the input conductor. Traditional copper bar assemblies consisted of a copper bar and a fastening bolt at the input terminal, secured by a locking nut. This resulted in very high temperatures at the contact point between the bolt and the copper bar, causing rapid temperature rise, which could lead to the current-carrying component glowing red, overheating, and even burning out, potentially causing a fire. Other methods included machining the fastening bolt and copper bar together in a single process, which was complex and inefficient; or welding, but this could result in the copper bar and bolt burning at high temperatures, and the complex process reduced the component's lifespan.

[0026] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1

[0028] Combined with appendix Figure 1-3 A current-carrying component includes a copper strip 1, which comprises two parts connected together to form a main body. The copper strip 1 includes an inlet portion 2 and an outlet portion 3, both of which are block structures. The inlet portion 2 and the outlet portion 3 are connected to form an integral structure, thereby allowing the inlet portion 2 to install the component in the vertical direction and the outlet portion to install the component in the front-back direction.

[0029] The inlet section 2 is placed horizontally, and the outlet section 3 can be vertically and centrally connected to the side of the inlet section 2. The bottom surfaces of the inlet section 2 and the outlet section 3 are flush and used to place the copper strip 1. The inlet section 2 is provided with a through hole, and a fastening bolt 4 is provided in the through hole. The fastening bolt 4 is installed on the through hole, and the relevant components for the inlet are installed on the fastening bolt 4. The relevant components for the inlet are fixed on the fastening bolt 4 by threaded engagement.

[0030] The nut of the fastening bolt 4 is provided with a rib 5. The rib 5 is composed of multiple protrusions surrounding the bolt of the fastening bolt 4. The protrusions are intermittently distributed to prevent the fastening bolt from rotating after installation. The rib 5 is formed by the surface of the nut facing the bolt and surrounding the bolt. The outer surface of the rib 5 is inclined, sloping outward from one end facing the bolt to the other end. The fastening bolt 4 with the rib 5 is inserted into the through hole of the part by stamping. The rib 5 is inserted into the through hole at the same time. The fastening bolt is fixed in the through hole by interference fit. The inclined structure of the outer surface of the rib 5 facilitates the interference fit between the rib 5 and the through hole, so that the fastening bolt 4 is in full contact with the through hole and cannot be disconnected.

[0031] The fastening bolt 4 is in close contact with the end face of the copper strip 1, and the fastening bolt 4 and the copper strip 1 have better perpendicularity.

[0032] The fastening bolt 4 passes through the through hole into the inlet section 2. The bolt of the fastening bolt 4 is vertically upward. An inlet lug 13 is fitted onto the fastening bolt 4. The inlet lug 13 is used to connect with the inlet wire to achieve circuit connection. One end of the inlet lug 13 has a through hole for installation on the fastening bolt 4, and the other end is used to connect the inlet wire. From bottom to top, a flat washer 6, a disc washer 7, and a locking nut 8 are fitted onto the inlet lug 13 on the fastening bolt 4. The locking nut 8 is used to fasten the inlet lug 13 to the inlet section 2. The disc washer 7 can effectively increase pressure, reduce wear, and prevent loosening, thereby ensuring the stability and reliability of the inlet lug 13. The flat washer 6 can make the inlet lug 13 evenly stressed, so that the inlet lug 13 is subjected to uniform pressure towards the limit part. Under the action of the locking nut 8, the inlet lug 13 and the inlet wire of the copper strip 1 are fully in contact, thereby stably achieving circuit connection.

[0033] The copper strip 1 has a through-hole 9 on its lead-out portion 3. A fixing hole 10 is connected to the upper side of the lead-out hole 9. The lead-out hole 9 and the fixing hole 10 are correspondingly arranged. The lead-out hole 9 is used to insert the lead-out cable 11. The fixing hole 10 is provided with an internal thread. The internal thread in the fixing hole 10 is used to screw in a set screw 12. After the lead-out cable is inserted into the lead-out hole 9, the set screw 12 is screwed into the fixing hole 10. By rotating and pressing down in the fixing hole 10, the lead-out cable is fixed in the lead-out hole 9. The set screw 12 is installed on the lead-out cable through the fixing hole 10. This is not only convenient, but also has a self-locking function, which can prevent the lead-out cable 11 from accidentally coming out of the lead-out hole 9 during long-term use. The number of wire exit holes 9 in the wire exit section 3 of the copper strip 1 is not limited. The wire exit section 3 can be provided with multiple wire exit holes 9, and the diameter of each wire exit hole 9 can be varied, so as to facilitate the connection of wire exit cables 11 of different sizes or specifications. Each wire exit hole 9 is provided with a corresponding fixing hole 10. The fixing hole 10 is used to directly fix the wire exit cable 11 in the wire exit hole 9 after inserting the wire exit cable 11 into the corresponding wire exit hole 9, which is convenient and quick.

[0034] The fastening bolt 4 is installed on the inlet section 2 of the copper strip 1 by stamping through the rib 5. Compared with the traditional direct threaded fastening, this avoids the high temperature and rapid heating at the contact point between the wire lug and the copper strip 1. Compared with the method of directly machining the fastening bolt 4 and the copper strip 1 in one step, it reduces costs. Compared with the method of welding the fastening bolt 4 and the copper strip 1, it has a longer service life and more stable performance.

[0035] When using, fix the copper strip inside the electrical box, connect the outgoing cable, tighten the set screw, and at the same time, put the incoming wire lug onto the fastening bolt. Then, put in the flat washer and the wing washer in sequence, and use a socket wrench to tighten the lock nut. Apply high torque to the lock nut to firmly fix the incoming wire lug onto the end face of the copper strip.

[0036] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
