Description

Technical Field

[0001] The invention relates to the technical field of wiping static contact pieces, in particular to a fixing structure for protecting wiping static contact pieces. Background Art

[0002] Static contacts are essential components of relays and other electrical devices. They are typically made of metal materials with good electrical conductivity and a certain degree of elasticity. They are fixed to the relay's base or bracket. When the relay coil is energized or de-energized, the corresponding moving contact moves accordingly, making or breaking contact with the static contact, thereby controlling the circuit's on / off state. The performance of the static contact directly affects the relay's reliability and stability. Its contact surface must be smooth and flat to ensure good contact with the moving contact, reduce contact resistance, and ensure accurate transmission of circuit signals.

[0003] Before electrical equipment is put into operation, the static contacts need to be carefully wiped and maintained, and this process is often completed with the help of power tools. However, as a key component of the relay, the static contacts are mostly made of thin elastic metal materials and are relatively fragile. When the power tool acts on its surface, the high-speed brush head or wiping component will generate a large external force. If the operation is improper, it will easily cause the static contacts to deform. Once deformation occurs, it will not only change the contact state between the static contact and the dynamic contact, but also destroy the original pressure balance. As a result, there will be significant errors in the pressure stability of the static contacts before and after wiping, resulting in problems such as contact resistance fluctuations and unstable signal transmission, which will seriously affect the normal working performance and service life of the relay, and may even cause electrical equipment failures, threatening the safe and stable operation of the entire system. Summary of the Invention

[0004] In order to solve the above-mentioned problems, the present invention proposes a fixing structure for protecting the wiping static contact piece, which has a good fixing effect on the static contact piece, prevents deformation during electric wiping, and ensures the stability of its working state.

[0005] In order to solve the above technical problems, the present invention proposes a technical solution: a fixing structure for protecting a wiping static contact sheet, comprising:

[0006] An arranged static contact seat is provided with harness holes extending through the upper and lower bottom surfaces, and is also fixed with a plurality of static contact pieces, the ends of which extend to one side of the arranged static contact seat;

[0007] The fixed seat is placed on the arranged static contact seat, the rear end is provided with a harness groove, and the front end is integrally formed with a positioning block and a support block. The positioning block and the support block are arranged between two adjacent static contact pieces and are distributed alternately one by one. The support block is integrally formed with a support protrusion on the side close to the static contact piece.

[0008] Furthermore, the static contact piece is embedded in the distributed static contact base, and its upper wall does not exceed the upper wall of the distributed static contact base.

[0009] Furthermore, the wire harness grooves correspond to the wire harness holes one by one, and their inner walls are flush with the inner walls of the wire harness holes.

[0010] Furthermore, reinforcing blocks are fixedly connected to the joints where the upper walls of the positioning block and the support block are connected to the fixed seat.

[0011] Furthermore, the forward extension length of the support block is greater than that of the positioning block.

[0012] Furthermore, the edges of the side walls of the support protrusions are all smooth arc surfaces.

[0013] The advantages of the present invention compared with the prior art are as follows: The fixed seat is closely attached to the distributed static contact base. Its positioning block and support block are alternately placed between the static contact pieces. The support block is longer and has support protrusions with smooth arc surfaces, which can not only provide strong support but also avoid scratching the surface of the contact piece and prevent the generation of metal debris from affecting the performance of the relay. At the same time, the wire harness grooves correspond precisely to the wire harness holes, and their inner walls are flush, ensuring smooth passage of the wire harness, avoiding damage during wiping, and reducing the risk of contact instability caused by wire harness problems. In addition, the reinforcing blocks at the joints of the positioning block and the support block enhance the overall stability of the fixed seat. During the electric wiping process, they effectively inhibit the deformation of the static contact piece, enabling it to maintain a stable working state and ensuring the reliability and stability of the relay operation.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Combined with the attached Figure 1, Appendix Figure 2 , Appendix Figure 5 , A fixing structure for protecting wiping static contact pieces, comprising: an arranged static contact seat 1, on which there are wire harness holes 2 penetrating through the upper and lower bottom surfaces, and a plurality of static contact pieces 3 are fixedly arranged. The end of the static contact piece 3 extends to one side of the arranged static contact seat 1. The static contact piece 3 is embedded in the arranged static contact seat 1, and its upper wall does not exceed the upper wall of the arranged static contact seat 1, which can ensure the stability of the static contact piece 3 and at the same time facilitate the stable placement of the fixing seat 4 on the arranged static contact seat 1.

[0022] Combined with Appendix Figure 1 , Appendix Figure 2 , The fixing seat 4 is placed on the arranged static contact seat 1, and a wire harness groove 5 is opened at the rear end. The wire harness groove 5 corresponds to the wire harness hole 2 one by one, and the inner wall of it is flush with the inner wall of the wire harness hole 2, which is convenient for the wire harness to pass through smoothly and effectively prevents the contact wire harness from being damaged during the wiping process.

[0023] Combined with Appendix Figure 1 , Appendix Figure 3 , Appendix Figure 4 , A positioning block 6 and a support block 7 are integrally formed at the front end of the fixing seat 4. Reinforcing blocks 9 are fixedly connected at the joints where the upper walls of the positioning block 6 and the support block 7 are connected to the fixing seat 4, which enhances the stability of the positioning block 6 and the support block 7 and makes the fixing seat 4 not easy to loosen and deform during use.

[0024] Combined with Appendix Figure 1 , Appendix Figure 2 , Appendix Figure 4 , The positioning block 6 and the support block 7 are arranged between two adjacent static contact pieces 3 and are distributed alternately one by one. The forward extension length of the support block 7 is greater than the forward extension length of the positioning block 6, which can better support the static contact piece 3 and at the same time provide sufficient space for wiping.

[0025] Combined with Appendix Figure 1 , Appendix Figure 2 , A support protrusion 8 is integrally formed on the side of the support block 7 close to the static contact piece 3. The side edge of the support protrusion 8 is a smooth arc surface, which can prevent scratching the surface of the static contact piece 3 and avoid affecting the performance of the relay due to the generation of metal debris caused by scratching.

[0026] Specific embodiments of the present invention: Place the arranged static contact base 1 stably. Embed the static contact piece 3 on the arranged static contact base 1, with its end extending to one side and the upper wall not exceeding the upper wall of the arranged static contact base 1. Pass the wire harness through the wire harness hole 2 that penetrates the upper and lower bottom surfaces of the arranged static contact base 1, and then place the fixing base 4 on the arranged static contact base 1, so that the wire harness groove 5 at the rear end of the fixing base 4 corresponds to the wire harness hole 2 one by one, ensuring that the inner walls of the two are flush, ensuring that the wire harness passes through smoothly and protecting the wire harness. At this time, the positioning blocks 6 and the supporting blocks 7 at the front end of the fixing base 4 will be alternately distributed between two adjacent static contact pieces 3. Among them, the supporting block 7 extends forward longer, and the smooth arc surface of the supporting protrusion 8 on the side close to the static contact piece 3 closely adheres to the contact piece, playing a supporting role. At this time, the electric wiping tool can be inserted into the side of the static contact piece 3 at the front end of the positioning block 6 to perform the electric wiping work on the static contact piece 3. During the process, the fixing structure can stably protect the static contact piece and prevent it from deforming.
