Description

Technical Field

[0001] This utility model relates to the field of switch technology, specifically to a plug connection structure for a motorcycle dimmer switch. Background Technology

[0002] In a motorcycle's electrical system, the plug connection structure of the dimmer switch plays a crucial role. It is responsible for ensuring a stable electrical connection between the switch body and the external circuitry, guaranteeing the proper switching between high and low beams. However, in existing motorcycle dimmer switch plug connection structures, the connection between the stationary contact of the switch body and the conductive tabs on the plug often lacks effective waterproofing measures. When the motorcycle is driven in rainy weather or through flooded areas, moisture can easily penetrate the connection, causing oxidation and corrosion of the stationary contact and conductive tabs. This can lead to poor contact and even short circuits, severely affecting the normal operation of the motorcycle's lighting system and posing significant safety hazards. Therefore, there is an urgent need to design a motorcycle dimmer switch plug connection structure that can effectively improve waterproofing performance. Utility Model Content

[0003] To address the shortcomings in the prior art, this utility model provides a plug connection structure for a motorcycle headlight switch.

[0004] The technical solution adopted by this utility model is: a plug connection structure for a motorcycle dimmer switch, including a switch housing, a switch body and a plug. The switch body is installed inside the switch housing. A socket housing for connecting to the plug is provided on one side of the switch housing. The stationary contact piece of the switch body extends out from the socket housing. A conductive insert for connecting to the stationary contact piece is provided on the plug. An injection molding cavity is formed between the socket housing and the socket. A cover is provided on the injection molding cavity. An injection hole for injection into the injection molding cavity is provided on the cover.

[0005] The stationary contact and the conductive insert are connected to the injection molding cavity.

[0006] Furthermore, positioning pins extend from both sides of the plug, and positioning slots that engage with the positioning pins are provided on both sides of the socket housing.

[0007] An elastic plate is integrally formed on the bottom wall of the switch housing located on one side of the socket housing. The elastic plate has a limiting protrusion that protrudes toward the plug side. A limiting step that matches the limiting protrusion is provided on the bottom wall of the plug.

[0008] Furthermore, the socket housing is disposed perpendicular to the surface of the socket housing, and the plug is inserted perpendicularly into the side wall of the socket housing.

[0009] Furthermore, one end of the conductive insert is provided with a connecting groove that is adapted to connect with the stationary contact piece. After the connecting groove is inserted into the stationary contact piece, the connection is soldered.

[0010] Furthermore, the two ends of the cover are provided with elastic hanging rings, and the two sides of the socket housing are provided with fastening steps that connect with the elastic hanging rings.

[0011] Furthermore, guide step strips are provided on both sides of the elastic plate, and guide side plates inserted between the two guide step strips are provided on both sides of the limiting step.

If the specific posture changes, the directional indicators will also change accordingly.

[0026] This utility model provides a plug connection structure for a motorcycle dimmer switch.

[0027] In this embodiment, refer to Figure 1-4 The plug connection structure of the motorcycle dimmer switch includes a switch housing 1, a switch body 2, and a plug 3. The switch body 2 is installed inside the switch housing. A socket housing 4 for connecting to the plug is provided on one side of the switch housing 1. A stationary contact 5 of the switch body 1 extends out from the socket housing. A conductive insert 6 for connecting to the stationary contact 5 is provided on the plug. An injection molding cavity 7 is formed between the socket housing and the socket. A cover 8 is provided on the injection molding cavity 7. An injection hole 9 for injecting into the injection molding cavity is provided on the cover 8.

[0028] The stationary contact and the conductive insert are connected to the injection molding cavity.

[0029] In the above technical solution, an injection-molded cavity is constructed between the socket shell and the socket. The cavity is sealed with a cap with injection holes. The connection between the stationary contact and the conductive insert is placed inside the cavity. The cavity is filled by injection molding material (such as waterproof glue) through the injection holes to form a sealed environment.

[0030] After the injection-molded body (such as waterproof adhesive) is filled, it plays a sealing and protective role at the connection between the static contact piece and the conductive insert, preventing the intrusion of external substances such as moisture and dust, avoiding oxidation and corrosion of the connection parts, greatly improving the waterproof performance and electrical connection stability of the connection structure, and extending the service life of the dimmer switch.

[0031] Specifically, the plug has positioning pins 10 extending from both sides, and the socket housing has positioning slots 11 on both sides that engage with the positioning pins 10.

[0032] An elastic plate 12 is integrally formed on the bottom wall of the switch housing located on one side of the socket housing. The elastic plate 12 has a limiting protrusion 13 protruding towards the plug side. A limiting step 14 adapted to the limiting protrusion is provided on the bottom wall of the plug.

[0033] In this embodiment, the positioning pins on both sides of the plug are engaged with the positioning slots of the socket housing to achieve initial positioning of the plug and the socket housing; the elastic plate and limiting protrusion on the bottom wall of the switch housing are engaged with the limiting step on the bottom wall of the plug to restrict its movement after the plug is inserted.

[0034] The engagement of the positioning pins and the positioning slots ensures accurate installation of the plug and prevents misalignment; the engagement of the elastic plate and the limiting protrusion with the limiting step ensures a secure connection of the plug. Even if the motorcycle vibrates while driving, the plug is not easy to loosen or fall off, ensuring the reliability of the circuit connection and reducing the risk of failure caused by poor contact.

[0035] Specifically, the socket housing is arranged perpendicular to the surface of the socket housing, and the plug is inserted perpendicularly into the side wall of the socket housing.

[0036] In this embodiment, the socket housing is set perpendicular to the socket, and the plug is inserted vertically into the side wall of the socket housing, forming a vertical insertion connection method, which makes the connection structure layout compact and saves space.

[0037] Specifically, one end of the conductive insert is provided with a connecting groove 15 that is adapted to connect with the stationary contact piece. After the connecting groove is inserted into the stationary contact piece, it is soldered together.

[0038] In this embodiment, a connecting groove adapted to the stationary contact is provided at one end of the conductive insert. After the stationary contact is inserted into the connecting groove, welding is performed to achieve close contact between the two and form a stable electrical connection.

[0039] Specifically, the two ends of the cover are provided with elastic hanging rings 16, and the two sides of the socket housing are provided with fastening steps 17 that connect with the elastic hanging rings 16.

[0040] In this embodiment, the elastic hanging rings at both ends of the cover are connected to the snap-fit ​​steps on both sides of the socket housing, and the elastic deformation of the elastic hanging rings enables the cover and the socket housing to be quickly and tightly assembled.

[0041] Specifically, the elastic plate is provided with guide step strips 18 on both sides, and the limiting step is provided with guide side plates 19 inserted between the two guide step strips on both sides.

[0042] In this embodiment, the guide step strips on both sides of the elastic plate cooperate with the guide side plates on both sides of the limiting step. During the insertion of the plug, the guide side plates slide along the guide step strips to guide the plug to be inserted accurately, while also further limiting the plug.

[0043] Specifically, the plug has positioning protrusions 20 extending on both sides of the stationary contact piece, and the positioning protrusions 20 abut against the side walls on both sides of the injection molding cavity.

[0044] In this embodiment, the plug extends positioning protrusions on both sides of the stationary contact piece. The positioning protrusions abut against the side walls of the injection molding cavity. After the plug is inserted, it is positioned and limited to ensure that the plug position is fixed, thereby further improving the connection stability and accuracy.

[0045] Specifically, a sealing gasket 21 is provided on the bottom wall of the plug's socket.

[0046] In this embodiment, a sealing gasket is provided on the bottom wall of the plug's socket. When the plug is inserted into the socket housing, the sealing gasket is compressed and deformed, filling the gap between the plug and the socket housing. The sealing gasket effectively prevents external substances such as moisture and dust from entering the connection structure through the insertion gap between the plug and the socket housing, further enhancing the waterproof and dustproof performance.
