Description

Technical Field

[0001] This utility model relates to the field of copper foil welding contact head technology, and in particular to a copper foil welding contact head for a voltage regulator. Background Technology

[0002] Contacts are the main conductive contact materials used in relays, contactors, load switches, medium and low voltage circuit breakers, as well as household appliances, automotive electrical appliances and other switching devices. Switching devices are widely used to separate or close voltage or current in circuits, and their reliability directly affects the reliable operation of the entire power system. Electrical contacts are one of the important components of switching devices, and contact products are the "heart" of these products. Traditional copper foil soldering contacts for voltage regulators have some drawbacks. In the process of fixing the foil soldering contacts, the conventional practice is to directly solder them to the equipment. However, due to the limitations of the installation position, some contacts cannot achieve sufficient contact with the equipment. This insufficient contact may cause a series of problems, such as unstable power supply, which will have a negative impact on the long-term use of the equipment and may even shorten the service life of the equipment. Utility Model Content

[0003] The main objective of this invention is to provide a copper foil welding contact head for a voltage regulator, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A voltage regulator copper foil welding contact head includes a mating bar. A contact auxiliary mechanism is provided at the rear end of the mating bar. The contact auxiliary mechanism includes a support auxiliary bar fixedly connected to the rear end of the mating bar. One end of the support auxiliary bar has a sliding groove. A sliding block is slidably connected to the inner side of the sliding groove. One end of the sliding block is fixedly connected to a contact body. The contact body has a mating groove inside. A main pad block is fixedly connected to the inner wall of the mating groove. A secondary pad block is fixedly connected to one end of the main pad block. A limiting rod is fixedly connected to the upper end of the contact body. A mating frame is fixedly connected to the outer side of the limiting rod. A connecting frame is fixedly connected to the lower end of the mating frame. A threaded head is threaded onto the inner side of the connecting frame.

[0005] Preferably, the supporting auxiliary strip is arc-shaped, the sliding block has a T-shaped cross-section, and the other end of the auxiliary pad block is fixedly connected to the inner wall of the docking groove.

[0006] Preferably, the volume of the secondary pad block is smaller than the volume of the main pad block, and the shape of the docking frame is L-shaped.

[0007] Preferably, the docking frame is located above the contact body, and the connecting frame is located above the support auxiliary strip.

[0008] Preferably, the threaded head extends into the interior of the support auxiliary bar, and the threaded head is threadedly connected to the support auxiliary bar. There are two sets of contact auxiliary mechanisms, and the two sets of contact auxiliary mechanisms are centrally symmetrically distributed.

[0009] Preferably, a welding strip is fixedly connected to the front end of the mating strip, and there are two sets of mating strips. The two sets of mating strips are centrally symmetrically distributed, and both sets of mating strips are connected to the welding strip.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. By locking the sliding block in the sliding groove and then pushing the contact body, the contact body drives the sliding block to slide in the sliding groove, and the position of the contact body on the support strip changes. This makes it easy to adjust the position of the contact body, so that the contact body can adapt to the installation position of different equipment, and the contact body can firmly contact the equipment, thereby ensuring the power supply stability of the equipment.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] like Figure 1-4As shown, a voltage regulator copper foil welding contact head includes a mating bar 1. A contact auxiliary mechanism 3 is provided at the rear end of the mating bar 1. The contact auxiliary mechanism 3 includes a support auxiliary bar 31 fixedly connected to the rear end of the mating bar 1. A sliding groove 32 is provided at one end of the support auxiliary bar 31. A sliding block 33 is slidably connected to the inner side of the sliding groove 32. A contact body 34 is fixedly connected to one end of the sliding block 33. A mating groove 35 is provided inside the contact body 34. A main pad block 36 is fixedly connected to the inner wall of the mating groove 35. A secondary pad block 37 is fixedly connected to one end of the main pad block 36. A limiting rod 38 is fixedly connected to the upper end of the contact body 34. A mating frame 39 is fixedly connected to the outer side of the limiting rod 38. A connecting frame 310 is fixedly connected to the lower end of the mating frame 39. A threaded head 311 is threadedly connected to the inner side of the connecting frame 310.

[0016] In this embodiment, the support auxiliary strip 31 is arc-shaped, the cross-section of the sliding block 33 is T-shaped, the other end of the auxiliary pad block 37 is fixedly connected to the inner wall of the docking groove 35, the volume of the auxiliary pad block 37 is smaller than the volume of the main pad block 36, the docking frame 39 is L-shaped, the docking frame 39 is located above the contact body 34, the connecting frame 310 is located above the support auxiliary strip 31, the threaded head 311 extends into the interior of the support auxiliary strip 31, the threaded head 311 is threadedly connected to the support auxiliary strip 31, and there are two sets of contact auxiliary mechanisms 3, which are centrally symmetrically distributed.

[0017] Specifically, the sliding block 33 is engaged in the sliding groove 32, and the contact body 34 is pushed, causing the sliding block 33 to slide within the sliding groove 32. This changes the position of the contact body 34 on the support auxiliary bar 31, adjusting the contact body 34 to contact the equipment. Then, the threaded head 311 is screwed into the inner side of the connecting frame 310 and into the support auxiliary bar 31. The threaded head 311, through the connecting frame 310, the docking frame 39, and the limiting rod 38, limits the position of the contact body 34 on the support auxiliary bar 31, ensuring that the support auxiliary bar 31 firmly contacts the equipment. The main pad block 36 in the docking groove 35... Under the action of the auxiliary pad block 37, the main pad block 36 and the auxiliary pad block 37 support the contact body 34, which reduces the probability of deformation of the contact body 34. By locking the sliding block 33 in the sliding groove 32 and pushing the contact body 34, the contact body 34 drives the sliding block 33 to slide in the sliding groove 32, and changes the position of the contact body 34 on the support auxiliary strip 31. This makes it easier to adjust the position of the contact body 34, so that the contact body 34 can adapt to the installation position of different equipment, and can firmly contact the equipment, thereby ensuring the power supply stability of the equipment.

[0018] In this embodiment, a welding strip 2 is fixedly connected to the front end of the docking strip 1. There are two sets of docking strips 1, which are centrally symmetrically distributed and connected to the welding strip 2.

[0019] Specifically, the welding rod 2 is first welded to the designated position inside the equipment, so that the welding rod 2 can stand the butt bar 1 upright inside the equipment, which can facilitate the preliminary installation preparation work of the contact body 34.

[0020] Working principle: In use, firstly, weld the welding rod 2 to the designated position inside the equipment, so that the welding rod 2 erects the butt bar 1 inside the equipment. Then, lock the sliding block 33 into the sliding groove 32, and push the contact body 34, causing the sliding block 33 to slide within the sliding groove 32. This changes the position of the contact body 34 on the support auxiliary bar 31 and adjusts the contact body 34 to contact the equipment. Then, screw the threaded head 311 into the inside of the connecting frame 310 and into the support auxiliary bar 31. The threaded head 311, through the connecting frame 310, the butt frame 39, and the limiting rod 38, limits the position of the contact body 34 on the support auxiliary bar 31, thus firmly connecting the support auxiliary bar 31. When the contactor touches the equipment, and under the action of the main pad block 36 and the auxiliary pad block 37 in the mating groove 35, the main pad block 36 and the auxiliary pad block 37 support the contact body 34, which can reduce the probability of deformation of the contact body 34. By locking the sliding block 33 in the sliding groove 32 and pushing the contact body 34, the contact body 34 drives the sliding block 33 to slide in the sliding groove 32, and changes the position of the contact body 34 on the support auxiliary strip 31, so as to facilitate the adjustment of the position of the contact body 34. This allows the contact body 34 to adapt to the installation position of different equipment, and allows the contact body 34 to make firm contact with the equipment, thereby ensuring the power supply stability of the equipment.
