Abstract
Description
Technical Field
[0001] This utility model relates to the field of disc brake switch technology, specifically to a wire clamping structure for a motorcycle disc brake switch. Background Technology
[0002] In motorcycle braking systems, the disc brake switch, as a critical signal triggering component, directly affects the overall vehicle's driving safety and handling reliability due to its operational stability. Disc brake switches typically transmit signals to the vehicle's electrical system via outgoing wires, and the wire clamping structure design between the outgoing wires and the switch housing is a core element determining the stability of the outgoing wire connection, its resistance to external interference, and its service life.
[0003] Currently, the wiring structures of common motorcycle disc brake switches on the market generally have design limitations when dealing with the arrangement and fixing of multiple wires. Most structures do not have a dedicated separating and positioning mechanism for multiple wires, which makes it easy for the wires to become tangled and misaligned in the wiring cavity. This not only increases the difficulty of the assembly process, but may also cause signal transmission failures due to poor wire contact, affecting the normal triggering function of the disc brake switch.
[0004] Meanwhile, in terms of tensile strength, traditional cable clamping structures are insufficient in securing the cable exiting the motorcycle. During motorcycle operation, the cable exiting the motorcycle is easily subjected to external forces such as bumps, vibrations, or accidental pulling. If the cable clamping structure cannot provide reliable securing force, the connection between the wire and the stationary contact plate can easily become loose or even detach, leading to disc brake switch failure and posing a significant safety hazard.
[0005] Furthermore, the sealing and protection performance is also a weak point of traditional wire-pressing structures. If the connection between the cable outlet and the housing is not sealed tightly, external dust, moisture, oil, and other impurities can easily enter the wiring cavity through the gaps, causing corrosion or short-circuit damage to internal components such as the stationary contact plate and wires. This significantly reduces the environmental adaptability and service life of the disc brake switch, making it difficult to meet the long-term use requirements of motorcycles under complex operating conditions. Utility Model Content
[0006] To address the shortcomings in the prior art, this utility model provides a wire clamping structure for a motorcycle disc brake switch.
[0007] The technical solution adopted by this utility model is: a wire pressing structure for a motorcycle disc brake switch, including a housing, a stationary contact piece and a wire outlet. The housing includes a middle shell and a lower cover covering the middle shell. A wiring cavity is formed between the middle shell and the lower cover. The wire outlet includes a rubber sleeve and multiple wires inside the rubber sleeve. The stationary contact piece has a wiring terminal that extends into the wiring cavity and connects with the wires. The wiring cavity is provided with a positioning groove for separating and positioning each wire. One end of the wiring cavity extends into a wire outlet hole, which is adapted to the size of the rubber sleeve. A clamping mechanism for pressing the wire outlet is provided in the wire outlet hole.
[0008] Furthermore, the end face where the middle shell and the lower cover are closed has a lower end face and a side end face. The lower two sides of the side end face are provided with insertion ports, and the upper side is provided with a buckle. The lower end face extends to the end away from the side end face with a plug-in portion. The lower cover has protrusions on both sides of one end for insertion into the socket, and an elastic hook on the top of the lower cover for fastening with the buckle. The other end of the lower cover has a sleeve with the aforementioned cable outlet hole inside, and the inner wall of the bottom of the sleeve has a fitting groove into which the aforementioned insertion part is embedded.
[0009] Furthermore, the plug-in portion has an arc-shaped surface with the same diameter as the wire outlet hole.
[0010] Furthermore, the positioning groove is disposed on the lower end face.
[0011] Furthermore, the lower cover is provided with an injection hole for pouring sealant into the wiring cavity.
[0012] Furthermore, the pressing mechanism is a pressure cap, and a pressure cap hole is provided on the outer wall of the wire outlet sleeve hole. The pressure cap has a part that extends into the wire outlet sleeve hole to press the wire.
[0013] Furthermore, the middle part of the pressure cap is provided with an annular groove that fits into the wall of the pressure cap hole, and the top of the pressure cap is provided with an inlet slope.
[0014] Furthermore, the clamping mechanism is provided with extrusion ribs on the inner wall of the cable outlet hole, and the extrusion ribs are located inside the sleeve of the lower cover or on the insertion part of the middle shell.
[0015] The beneficial effects of this utility model are: 1. Achieve orderly fixation of multiple wires: This patent allows for independent separation and positioning of each wire by setting a special positioning groove in the wiring cavity, which facilitates the welding of wires to the stationary contact piece and effectively avoids the problems of wires tangling and misalignment in traditional structures.
[0016] 2. Enhanced tensile strength and improved structural connection reliability: The cable outlet hole at one end of the wiring cavity is size-matched to the cable outlet rubber sleeve, and the clamping mechanism within the hole provides a secure clamping effect for the cable. This effectively prevents the connection between the wire and the stationary contact plate from loosening or falling off, fundamentally eliminating disc brake switch malfunctions caused by cable fixing failure, further ensuring driving safety and extending the switch's service life.
[0017] 3. Optimized Sealing Protection: The matching design of the cable outlet hole and the rubber sleeve, combined with the tight clamping mechanism, forms a reliable sealing structure at the connection between the cable outlet and the housing, effectively preventing external dust, moisture, oil, and other impurities from entering the wiring cavity. This prevents corrosion or short-circuit damage to internal components such as the stationary contact plate and wires due to impurities, significantly improving the disc brake switch's resistance to harsh environments. This allows it to reliably adapt to the complex operating conditions of motorcycles in rainy weather, muddy roads, etc., further extending the switch's lifespan and reducing subsequent maintenance costs.
