Description

Technical Field

[0001] The utility model relates to the technical field of micro switches, in particular to a potting housing structure of a micro switch. Background Art

[0002] In the manufacturing and application of electronic devices, the micro switch with a wire harness, as a key component, is widely used in various control systems. Its performance stability and waterproof performance are directly related to the safety and reliability of the entire system. To improve the waterproof performance of the terminal part, the industry often uses methods such as potting or low-voltage overmolding for encapsulation. Specifically, a potting sleeve is installed on the side where the terminal and the wire harness are connected, and potting glue is injected into this sleeve to enhance the sealing of the terminal and prevent moisture intrusion. However, in traditional designs, in order to fix the potting sleeve and enhance its sealing performance, it is often necessary to add snap structures on both sides of the sleeve. These additional snap designs not only increase the overall volume of the switch, but also limit its application in space-constrained scenarios. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a potting housing structure of a micro switch to solve the problem that adding snap structures on both sides of the traditional potting sleeve increases the overall volume of the micro switch.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A potting housing structure of a micro switch includes: a micro switch body, a base, and a wire harness. The micro switch body is fixed on one side of the base, and the wire harness is located on the other side of the base. The micro switch body includes a conductive terminal, and one end of the conductive terminal penetrates through the base along the thickness direction of the base and is connected to the wire harness. A housing is installed on the other side of the base, and a cavity is formed inside the housing. One end of the conductive terminal and at least part of the wire harness are located inside the cavity. A boss is formed on the other side of the base, and a groove is formed on the boss. A first insertion block is formed on the inner side wall of the housing, and the first insertion block is adapted to the groove. The first insertion block can be inserted into the groove so that the housing is installed on the other side of the base.

[0006] According to the above technical means, the utility model simplifies the structure by inserting the first insertion block on the inner side wall of the housing into the groove on the base, significantly reducing the number and volume of external structural parts, and making the overall size of the micro switch more compact.

[0007] In this utility model, the conductive terminals and at least part of the wire harness are placed in the cavity inside the housing. The cavity is used for filling with potting glue, thereby forming an effective waterproof barrier to prevent impurities such as moisture and dust in the external environment from invading, and ensuring the working stability and reliability of the micro switch.

[0008] Further, a first sliding groove is formed on one side of the boss adjacent to the groove, and the first sliding groove is distributed along a first direction; a second insert block is formed on an inner side wall of the housing adjacent to the first insert block, and the second insert block is adapted to the first sliding groove, and the second insert block can move along the first direction in the first sliding groove.

[0009] According to the above technical means, the cooperation of the first sliding groove and the second insert block not only provides an additional positioning reference, but also limits the degree of freedom of movement of the housing on the base, enhances the stability of the overall structure, and helps to prevent the housing from loosening or falling off due to vibration or external impact.

[0010] The housing is firmly installed on the base through the cooperation of the groove and the first insert block, and the first sliding groove and the second insert block, providing better protection for the internal conductive terminals and wire harness, and reducing the risk of damage caused by external impact or vibration.

[0011] Further, a second sliding groove is formed on the other side of the boss adjacent to the groove, and the second sliding groove is distributed along the first direction; a third insert block is formed on the other inner side wall of the housing adjacent to the first insert block, and the third insert block is adapted to the second sliding groove, and the third insert block can move along the first direction in the second sliding groove.

[0012] According to the above technical means, the cooperation of the two sliding grooves and the two insert blocks in this utility model provides a dual positioning mechanism, ensuring the accurate installation and stable connection of the housing on the base, significantly improving the stability of the overall structure, and reducing the risk of loosening or falling off caused by vibration or external impact.

[0013] Further, the first sliding groove and the second sliding groove are symmetrically distributed relative to the groove, and the second insert block and the third insert block are symmetrically distributed relative to the first insert block.

[0014] According to the above technical means, the symmetrical design of the sliding grooves and insert blocks makes the whole structure more beautiful in appearance and more balanced in mechanics, which helps to reduce the risk of structural damage caused by asymmetric stress concentration. At the same time, since the sliding grooves and insert blocks are symmetrically distributed, it is easier to achieve precise alignment during the installation process, reducing the installation difficulty and reducing the performance problems caused by improper installation.

[0015] Further, the number of the grooves is two, and the two grooves are symmetrically distributed on opposite sides of the boss; each groove extends towards the inside of the boss.

[0016] According to the above technical means, the two grooves provide two options for the installation of the first plug, enabling the housing to be installed in either direction during installation, thus improving the installation efficiency.

[0017] Furthermore, the first plug, the second plug, and the third plug are all wedge-shaped structures.

[0018] According to the above technical means, when the wedge-shaped structure is inserted into the chute or groove, due to its shape characteristics, the contact area with the chute or groove will gradually expand, thereby generating a stronger locking force, which helps to prevent the housing from loosening or falling off the base, improving the stability and reliability of the overall structure. At the same time, the plug of the wedge-shaped structure has self-guidance when inserted into the chute or groove, enabling more accurate alignment to be achieved more easily.

[0019] Furthermore, a limiting member is formed on the inner wall of the housing, and the limiting member can abut against the boss.

[0020] According to the above technical means, the limiting member, as an additional fixing point, can further limit the movement range of the housing on the base, thereby enhancing the stability and reliability of the installation. Even when other fixing methods (such as the cooperation between the plug and the chute) are subjected to certain impacts or vibrations, the limiting member can provide additional support and locking functions. At the same time, the presence of the limiting member ensures that the housing stops moving at the correct position, thus preventing the housing from being inserted too far into the base during installation and avoiding structural damage or performance problems caused by over-insertion.

[0021] Furthermore, the number of the limiting members is two, and the two limiting members are symmetrically arranged on both sides of the first plug.

[0022] According to the above technical means, the symmetrically arranged limiting members help to ensure that the housing can maintain the correct position and posture during installation.

[0023] Furthermore, a first limiting surface and a second limiting surface are formed on each limiting member, and the first limiting surface and the second limiting surface can respectively abut against the adjacent sides of the boss.

[0024] According to the above technical means, the first limiting surface and the second limiting surface are in close contact with the adjacent sides of the boss, providing an accurate positioning reference for the installation of the housing, ensuring that the housing can maintain the correct position and posture during installation, and reducing the installation error.

[0025] Furthermore, a through hole is formed on the housing, and at least part of the wire harness passes through the through hole into the cavity.

[0026] According to the above technical means, the design of the through hole allows the wire harness to penetrate directly into the cavity from the outside. This layout increases the flexibility of wiring, enabling the wire harness to be arranged more compactly and orderly in the cavity, reducing the clutter and redundancy of the cables.

[0027] Beneficial effects achieved by the present utility model:

[0028] 1. By the way that the first insertion block on the inner side wall of the housing is inserted into the groove on the base, the present utility model cancels the buckle structures added on both sides of the housing in the traditional design, simplifies the structure, significantly reduces the number and volume of external structural parts, and makes the overall size of the microswitch more compact.

[0029] 2. The present utility model places the conductive terminals and at least part of the wire harness in the cavity inside the housing, and the cavity is used for filling with potting glue, thereby forming an effective waterproof barrier to prevent impurities such as moisture and dust in the external environment from invading, and ensuring the working stability and reliability of the microswitch.

[0051] Embodiment 1

[0052] As Figure 1 and Figure 6 shown, this embodiment provides a potting housing structure for a microswitch, including: a microswitch body 1, a base 2 and a wire harness 3. The microswitch body 1 is fixed on one side of the base 2, and the wire harness 3 is located on the other side of the base 2; as Figure 1 、 Figure 3 and Figure 6 shown, the microswitch body 1 includes conductive terminals 11. One end of the conductive terminal 11 penetrates the base 2 along the thickness direction of the base 2 and is connected to the wire harness 3; as Figure 5 shown, a housing 4 is installed on the other side of the base 2. A cavity 41 is formed in the housing 4. One end of the conductive terminal 11 and at least part of the wire harness 3 are located in the cavity 41; a boss 21 is formed on the other side of the base 2, and a groove 22 is formed on the boss 21; a first insert block 42 is formed on the inner side wall of the housing 4. The first insert block 42 is adapted to the groove 22, and the first insert block 42 can be inserted into the groove 22 so that the housing 4 is installed on the other side of the base 2.

[0053] As Figure 1 and Figure 4 shown, before potting, one end of the wire harness 3 is fixedly connected to the conductive terminal 11 to ensure stable transmission of electrical signals. Then, the housing 4 is aligned with the other side of the base 2 and the housing 4 is pushed so that the first insert block 42 is gradually inserted into the groove 22 to ensure that the housing 4 is completely aligned with and tightly fitted to the base 2 to complete the connection between the housing 4 and the base 2. When potting, an appropriate amount of potting adhesive is poured into the cavity 41 of the housing 4 according to actual needs to protect the connection parts of the internal conductive terminals 11 and the wire harness 3, as well as the connection part between the housing 4 and the base 2. While improving the waterproof, dustproof and shockproof performance of the entire microswitch, it ensures that the connection between the housing 4 and the base 2 is more stable.

[0054] As Figure 2As shown, in this embodiment, by means of the insertion connection between the first insertion block 42 on the inner side wall of the housing 4 and the groove 22 on the base 2, the snap structures added to both sides of the housing 4 in the traditional design are eliminated, simplifying the structure, significantly reducing the number and volume of external structural components, and making the overall size of the microswitch more compact.

[0055] In the present utility model, the conductive terminals 11 and at least part of the wire harness 3 are placed in the cavity 41 inside the housing 4. The cavity 41 is used for filling with potting glue to form an effective waterproof barrier, preventing impurities such as moisture and dust in the external environment from invading, and ensuring the working stability and reliability of the microswitch.

[0056] As Figure 6 shown, in this embodiment, the microswitch body 1 includes at least two conductive terminals 11. One end of each conductive terminal 11 passes through the boss 21 into the cavity 41, making the connection between the conductive terminal and the wire harness 3 more direct and reliable. At the same time, in this embodiment, the boss 21 is preferably a symmetric structure, and at least two conductive terminals 11 are distributed relatively along the symmetric center line, ensuring the balanced layout of them in the cavity 41, making the relative position between the conductive terminal and the wire harness 3 fixed and precise, and reducing the risk of poor contact or short circuit caused by position deviation.

[0057] As Figure 6 shown, in this embodiment, the boss 21 is designed as a symmetric structure, which not only makes the overall appearance more beautiful but also enhances the structural stability. The groove 22 is located at the symmetric center line of the boss 21, providing an accurate positioning reference for the installation of the housing 4. Through the insertion connection between the first insertion block 42 on the inner wall of the housing 4 and the groove 22, a firm connection is achieved, avoiding the risk of loosening and displacement.

[0058] As Figure 4 and Figure 6 shown, a first sliding groove 23 is formed on one side of the boss 21 adjacent to the groove 22, and the first sliding groove 23 is distributed along the first direction; a second insertion block 43 is formed on one inner side wall of the housing 4 adjacent to the first insertion block 42, and the second insertion block 43 is adapted to the first sliding groove 23, and the second insertion block 43 can move in the first sliding groove 23 along the first direction.

[0059] The cooperation between the first sliding groove 23 and the second insertion block 43 not only provides an additional positioning reference but also limits the freedom of movement of the housing 4 on the base 2, enhancing the overall structural stability and helping to prevent the housing 4 from loosening or falling off due to vibration or external impact.

[0060] The housing 4 is firmly installed on the base 2 through the cooperation of the groove 22 and the first insertion block 42, and the first sliding groove 23 and the second insertion block 43, providing better protection for the internal conductive terminals 11 and wire harness 3 and reducing the risk of damage caused by external impact or vibration.

[0061] During the specific installation process, the microswitch body 1 is located on one side of the base 2, and the conductive terminal 11 passes through the boss 21 and extends to the other side of the base 2. Connect the wire harness 3 to one end of the conductive terminal 11 located on the other side of the base 2. Place the housing 4 on the other side of the base 2 so that the second insertion block 43 aligns with the first chute 23. At this time, the first insertion block 42 should also correspond to the groove 22. Push the housing 4 so that the second insertion block 43 moves along the direction of the first chute 23 until the housing is completely installed in place. During this process, the first insertion block 42 will also be inserted into the groove 22 to achieve a firm connection between the housing 4 and the base 2.

[0062] As Figure 4 and Figure 6 shown, in this embodiment, the boss 21 is integrally in a cuboid structure, the first direction is the width direction of the boss, the first chute 23 is distributed on the wide side of the boss 21, and the groove 22 is located on the long side of the boss 21.

[0063] As Figure 4 and Figure 6 shown, a second chute 24 is formed on the other side of the boss 21 adjacent to the groove 22, and the second chute 24 is distributed along the first direction; a third insertion block 44 is formed on the other inner side wall of the housing 4 adjacent to the first insertion block 42, the third insertion block 44 is adapted to the second chute 24, and the third insertion block 44 can move in the second chute 24 along the first direction.

[0064] In this embodiment, the cooperation of the two chutes and the two insertion blocks provides a dual positioning mechanism to ensure the accurate installation and firm connection of the housing 4 on the base 2, significantly improving the stability of the overall structure and reducing the risk of loosening or falling off caused by vibration or external impact.

[0065] During the specific installation process, the microswitch body 1 is located on one side of the base 2, and the conductive terminal 11 passes through the boss 21 and extends to the other side of the base 2. Connect the wire harness 3 to one end of the conductive terminal 11 located on the other side of the base 2. Place the housing 4 on the other side of the base 2 so that the second insertion block 43 aligns with the first chute 23 and at the same time the third insertion block 44 aligns with the second chute 24. At this time, the first insertion block 42 should also correspond to the groove 22. Push the housing 4 so that the second insertion block 43 and the third insertion block 44 move simultaneously along the directions of their respective corresponding chutes (i.e., the first chute 23 and the second chute 24). During the movement, the first insertion block 42 will gradually be inserted into the groove 22. Continue to push the housing until it is completely installed in place. After the installation is completed, carefully check whether the installation position of the housing is accurate and whether there is any looseness or gap between the components. After confirming that the housing is installed correctly, pour an appropriate amount of potting adhesive into the cavity 41. After waiting for the potting adhesive to cure, the potted housing structure of the entire microswitch is completed.

[0066] As Figure 4 and Figure 6As shown, the first sliding groove 23 and the second sliding groove 24 are symmetrically distributed relative to the groove 22, and the second insertion block 43 and the third insertion block 44 are symmetrically distributed relative to the first insertion block 42.

[0067] The symmetric design of the sliding grooves and insertion blocks makes the whole structure more aesthetically pleasing in appearance and more balanced mechanically, helping to reduce the risk of structural damage caused by asymmetric stress concentration. At the same time, since the sliding grooves and insertion blocks are symmetrically distributed, it is easier to achieve precise alignment during installation, reducing the installation difficulty and minimizing performance problems caused by improper installation.

[0068] As Figure 4 and Figure 6 shown, the number of grooves 22 is two, and the two grooves 22 are symmetrically distributed on the opposite sides of the boss 21; each groove 22 extends into the interior of the boss 21.

[0069] The two grooves 22 provide two options for the installation of the first insertion block 42, enabling the housing 4 to be installed in either direction during installation, thus improving the installation efficiency.

[0070] As Figure 5 shown, the first insertion block 42, the second insertion block 43, and the third insertion block 44 are all wedge-shaped structures.

[0071] When the wedge-shaped structure is inserted into the sliding groove or the groove, due to its shape characteristics, it will gradually expand the contact area with the sliding groove or the groove, thereby generating a stronger locking force, which helps to prevent the housing 4 from loosening or falling off the base 2, improving the stability and reliability of the overall structure. At the same time, the wedge-shaped insertion block has self-guidance when inserted into the sliding groove or the groove, making it easier to achieve precise alignment.

[0072] As Figure 5 shown, a limiting member 45 is also formed on the inner wall of the housing 4, and the limiting member 45 can abut against the boss 21.

[0073] The limiting member 45, as an additional fixing point, can further limit the movement range of the housing 4 on the base 2, thereby enhancing the stability and reliability of the installation. Even when other fixing methods (such as the cooperation between the insertion block and the sliding groove) are subjected to certain impacts or vibrations, the limiting member can also provide additional support and locking functions. At the same time, the presence of the limiting member 45 ensures that the housing stops moving at the correct position, thus preventing the housing 4 from being over-inserted into the base 2 during installation and avoiding structural damage or performance problems caused by over-insertion.

[0074] As Figure 5 shown, the number of limiting members 45 is two, and the two limiting members 45 are symmetrically arranged on both sides of the first insertion block 42.

[0075] The symmetrically arranged limit members 45 help to ensure that the housing can maintain the correct position and attitude during installation.

[0076] As Figure 5 shown, a first limit surface 451 and a second limit surface 452 are formed on each limit member 45, and the first limit surface 451 and the second limit surface 452 can respectively abut against adjacent sides of the boss 21.

[0077] The first limit surface 451 and the second limit surface 452 are in close contact with the adjacent sides of the boss 21, providing an accurate positioning reference for the installation of the housing 4, ensuring that the housing can maintain the correct position and attitude during installation, and reducing installation errors.

[0078] As Figure 5 shown, a through hole 46 is also formed on the housing 4, and at least part of the wire harness 3 passes through the through hole 46 into the cavity 41.

[0079] As Figures 1 - 6 shown, in this embodiment, the through hole 46 is a U-shaped hole. The design of the U-shaped hole allows the wire harness to have a certain bending space when passing through, which increases the flexibility of wiring. The wire harness can adjust its position and direction in the U-shaped hole as needed to adapt to different connection requirements or avoid interference with other components.

[0080] The through hole 46 is arranged on either side of the adjacent base 2. One end of each wire harness 3 passes through the through hole 46 and extends outside the housing 4, and is vertically distributed. The design of the through hole 46 allows the wire harness 3 to directly penetrate into the cavity 41 from the outside. This layout method increases the flexibility of wiring, enables the wire harness 3 to be arranged more compactly and orderly in the cavity, and reduces the clutter and redundancy of the cables.

[0081] Embodiment Two

[0082] A potting housing structure of a microswitch. This embodiment is similar to Embodiment One. For the same parts, refer to Embodiment One. The following only describes the improved parts.

[0083] As Figures 7 - 10 shown, in this embodiment, the through hole 46 is a U-shaped hole, and the number of through holes 46 is two. The two through holes 46 are arranged on the side away from the base 2, and each wire harness can respectively extend outside the housing 4 through each through hole 46. The arrangement of the two U-shaped holes in this embodiment allows the wire harness to be dispersed for wiring on both sides of the housing 4, which helps to reduce the concentration of cables on one side, improving the neatness and aesthetics of the overall layout. Compared with a single through hole, the two U-shaped holes can perform wiring operations simultaneously or separately, thus improving the wiring efficiency. Especially when connecting multiple external devices or sensors, this layout can significantly reduce the wiring time and cost.

[0084] The serial numbers of the embodiments of the present application above are only for description and do not represent the superiority or inferiority of the embodiments. The above are only the preferred embodiments of the present application and do not limit the patent scope of the present application accordingly. Any equivalent structural or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present application.
