Description

Technical Field

[0001] This utility model relates to a relay, and more particularly to a relay connection structure. Background Technology

[0002] A relay is an electrical control device that causes a predetermined step change in the controlled variable in the electrical output circuit when the change in the input quantity (excitation quantity) reaches a specified requirement. It has an interactive relationship between the control system (also known as the input circuit) and the controlled system (also known as the output circuit). It is commonly used in automated control circuits, essentially acting as an "automatic switch" that uses a small current to control a large current. Therefore, it plays a role in automatic adjustment, safety protection, and circuit switching. For some irregularly shaped contact connection structures, an overly convoluted structure affects service life and stability. It should also be noted that this type of relay is used in environments with special connection positions, different from conventional front and rear connections. Utility Model Content

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a relay connection structure, including a housing, a long contact piece, a short contact piece, a coil assembly, an armature, an elastic element, and a slider.

The housing is provided with a slide rail for the slider to move. The coil assembly drives the armature and the slider to move through electromagnetic action. The slider abuts against the end of the elastic element and moves in linkage. The long contact piece also has a connecting part and a fixing part outside the housing. The connecting part includes several strands of twisted wire. The long contact piece and the short contact piece are connected by contact current.

Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0012] like Figure 1 As shown, a relay connection structure includes a housing 1, a long contact piece 2, a short contact piece 3, a coil assembly 4, an armature, an elastic element 5, and a slider 6. The long contact piece 2 has a stationary contact end 7, and the short contact piece 3 has a moving contact end 8. One end of the elastic element 5 is fixedly abutted against the stationary contact end 7, and the other end of the elastic element 5 is fixedly connected to the moving contact end 8. The moving contact end 8 abuts against the stationary contact end 7 through the elastic element 5. The slider 6 is fixedly connected to the armature. The housing 1 has a slide rail for the slider 6 to move. The coil assembly 4 drives the armature and the slider 6 to move through electromagnetic action. The slider 6 abuts against the end of the elastic element 5 in a linked manner. The long contact piece 2 also has a connecting part 9 and a fixing part 10 outside the housing 1. The connecting part 9 includes several strands of twisted wire harness 11. The long contact piece 2 and the short contact piece 3 are electrically connected through contact. The armature drives the slider 6 to move, further driving the contact and disengagement between the long contact piece 2 and the short contact piece 3. Since the coil assembly 4, armature, and slider 6 inevitably occupy a large portion of the space, a long contact piece 2 is also present. In this embodiment, the elastic element 5 is a non-conductive component with a certain degree of elasticity, allowing for sufficient elastic deformation during traction. Most importantly, the relatively long length of the long contact piece 2 is used to design the flexible connection part 9, i.e., the connection part 9. The wire harnesses 11 are twisted together along the helical direction. In this embodiment, the wire harnesses 11 are first twisted together individually, and then multiple strands of the wire harnesses 11 are twisted together again to form a single large strand. It should be noted that this structure ensures the stability of the electrical connection and the freedom of connection of the long contact piece 2. In addition, the various wire harnesses 11 in the connection part 9 have a length margin or a certain degree of looseness, adapting to various installation angles and lengths without affecting the stability of the electrical connection. The fixing part 10 is provided with fixing holes for threaded connection and fixing, facilitating installation and assembly.

[0013] The slider 6 is equipped with a linkage 12, which hooks and abuts against the end of the elastic element 5. The elastic element 5 is deformed by the hook, a simple and reliable design. The linkage 12 and the slider 6 are fixedly connected in various reliable forms, which will not be elaborated or limited here. The housing 1 has a fixing groove 13 for the stationary contact 7 and the end of the elastic element 5 to be inserted into it. The elastic element 5 is a sheet-like structure, and the stationary contact 7 and one end of the elastic element 5 are fixed together in the fixing groove 13. Since the direction of the elastic or hooking action is perpendicular to the insertion direction, the elastic element 5 will not easily come out or affect the contact electrical connection. The housing 1 has several mounting grooves 14 for accommodating components. Appropriately sized grooves are designed for each component, which is beneficial for stable installation and optimized spatial layout. The housing 1 has cavities 15 on opposite sides of the fixing groove 13, which can slightly reduce the width of the fixing groove 13. The elastic contraction force of the fixing groove 13 relative to the groove wall is used to clamp the elastic element 5 and the stationary contact 7.
