Description

Technical Field

[0001] This utility model belongs to the field of connector technology, and in particular relates to a small waterproof connector for automotive mirrors. Background Technology

[0002] Inside the connector, a female terminal is usually installed inside the housing. The front of the housing has a socket corresponding to the female terminal. To prevent the female terminal from coming out of the socket, it needs to be blocked.

[0003] In existing technology, blocking the female terminal can be achieved by covering it with a front cover. However, if the connection between the front cover and the housing is not secure enough, or if the design is unreasonable, the front cover may loosen or shift during long-term use or when subjected to external forces. This can cause the female terminal to lose its effective blocking constraint, increasing the possibility of the female terminal coming off, and adversely affecting the normal use of the connector as well as the stability and reliability of the electrical connection.

[0029] Inside the connector's connection assembly, a female terminal is typically installed. A socket is provided at the front of the housing corresponding to the female terminal; to prevent the female terminal from dislodging from this socket, it must be blocked.

[0030] In existing technologies, blocking the female terminal is usually achieved by a front cover covering the female terminal. However, if the connection between the front cover and the housing is not secure enough, or if the design is unreasonable, the front cover may loosen or shift during long-term use or when subjected to external forces. This can cause the female terminal to lose its effective blocking constraint, increasing the possibility of the female terminal coming off, and adversely affecting the normal use of the connector as well as the stability and reliability of the electrical connection.

[0031] In view of this, the present invention provides a small waterproof connector for automotive mirrors, which aims to reduce the risk of the female terminal easily coming loose, so as to improve the stability and reliability of the electrical connection during use.

[0032] Please see Figure 2 and Figure 3 The connector includes a first connecting assembly 100, which includes a first housing 1 and a female terminal 2. The first housing 1 includes a housing body 11 and an abutment portion 12 disposed on the inner wall of the housing body 11. The housing body 11 extends in a front-rear direction. The front of the first housing 1 can be understood as the side for the male housing of the second connecting assembly 200 to be inserted, i.e., the side where the first socket 111 is located. The rear of the first housing 1 is the opposite side to the front. The inner wall of the housing body 11 forms a mounting cavity, and the female terminal 2 is installed in the mounting cavity. The female terminal 2 is installed in the mounting cavity in the following manner: the female terminal 2 enters the mounting cavity from the rear end of the housing body 11, causing the abutment portion 12 in the mounting cavity to deform. When the female terminal 2 is fully inserted into the mounting cavity, the abutment portion 12 returns to its original shape and abuts against the rear side of the female terminal 2, thereby effectively preventing the female terminal 2 from moving backward.

[0033] Furthermore, the first connecting assembly 100 also includes a front cover 3, which includes a cover body 31 and a locking portion 32 located on the rear side of the cover body 31. The cover body 31 abuts against the shell body 11, and the locking portion 32 extends into the mounting cavity and abuts against the abutment portion 12 to prevent deformation of the abutment portion 12, further enhancing the limiting effect on the female terminal 2. Specifically, when the female terminal 2 is installed in place, the abutment portion 12 abuts against the rear side of the female terminal 2, and at this time, the locking portion 32 abuts against the front side of the abutment portion 12, forming a double protection: on the one hand, the abutment portion 12 directly restricts the rearward movement of the female terminal 2, and on the other hand, the locking portion 32, by restricting the deformation of the abutment portion 12, prevents the abutment portion 12 from losing its elasticity due to external force or long-term use, thereby ensuring that the abutment portion 12 can always apply an effective blocking force to the female terminal 2, preventing the female terminal 2 from falling out of the mounting cavity.

[0034] Furthermore, the front end of the shell body 11 is formed with a first socket 111 and a stop wall 112 surrounding the first socket 111. The stop wall 112 extends along the vertical plane. After the female terminal 2 is installed in place, the stop wall 112 abuts against the front end face of the female terminal 2, thereby preventing the female terminal 2 from moving forward. The vertical plane is perpendicular to the front-back direction, that is, the front-back direction is perpendicular to the vertical plane. The front-back direction is represented by the dashed line a in the figure.

[0035] Since the stop wall 112 is formed from the front end of the shell body 11, the stop wall 112 is integrally formed into the shell body 11. The shell body 11 can be a metal shell or a plastic shell.

[0036] Compared with the traditional front cover 3 structure, the stop wall 112 makes more direct physical contact with the female terminal 2. Its blocking effect does not depend on the assembly stability of the front cover 3. Even when used for a long time or subjected to slight external impact, the double limiting structure of the stop wall 112 and the abutment part 12 can still maintain effective constraint on the female terminal 2, thereby significantly reducing the risk of the female terminal 2 coming off due to unidirectional limiting failure.

[0037] The connector provided by this utility model includes a first connecting assembly 100, which includes a first housing 1, a female terminal 2, and a front cover 3. The first housing 1 includes a housing body 11 and an abutment portion 12 disposed on the inner wall of the housing body 11. The housing body 11 extends along the front-rear direction, and the inner wall of the housing body 11 forms a mounting cavity. The female terminal 2 is installed in the mounting cavity. The abutment portion 12 abuts against the female terminal 2 to prevent the female terminal 2 from moving backward. The front cover 3 includes a cover body 31 and a locking portion 32 disposed on the rear side of the cover body 31. The cover body 31 abuts against the housing body 11, and the locking portion 32 extends into the mounting cavity to abut against the abutment portion 12. The front end of the housing body 11 forms a first insertion port 111 and a stop wall 112 surrounding the first insertion port 111. The first insertion port 111 is for the insertion of a male terminal. The stop wall 112 extends along a vertical plane and abuts against the female terminal 2 to prevent the female terminal 2 from moving forward. This embodiment of the invention forms a double-limiting structure for the female terminal 2 in the front and rear directions by providing a stop wall 112 integrally formed with the shell body 11 at the front end of the first housing 1, combined with the abutment portion 12 on the inner wall of the shell body 11. The stop wall 112 directly abuts against the front end face of the female terminal 2 to prevent it from moving forward, and the abutment portion 12 abuts against the rear side of the female terminal 2 to restrict its rearward movement. This design can constrain the female terminal 2 without relying on the assembly stability of the front cover 3, effectively avoiding the risk of the female terminal 2 falling off due to the loosening or displacement of the front cover 3. This improves the stability and reliability of the electrical connection of the first connection component 100 of the connector during use and extends the service life of the first connection component 100 of the connector.

[0038] In some embodiments, please refer to Figure 2 In order for the stop wall 112 to stably block the forward movement of the female terminal 2, the stop wall 112 blocks the end face of the front end of the female terminal 2 in the front-back direction.

[0039] In the front-rear direction, the projected area of ​​the stop wall 112 completely covers the front end face of the female terminal 2, ensuring that the stop wall 112 can provide uniform and sufficient support when the female terminal 2 is subjected to forward thrust, avoiding deformation of the front end face of the female terminal 2 or damage to the stop wall 112 due to excessive local force. This design makes the contact between the stop wall 112 and the female terminal 2 more compact and stable, further enhancing the blocking effect on the forward movement of the female terminal 2, thereby reducing the possibility of the female terminal 2 coming off due to uneven force during use.

[0040] In some embodiments, please refer to Figure 2 , Figure 3 and Figure 4 To achieve locking of the abutment portion 12, the front cover 3 and the shell body 11 were optimized. Specifically, a second insertion port 113 is formed at the front end of the shell body 11, and the second insertion port 113 is arranged in the front-rear direction; the cover body 31 abuts against the edge of the second insertion port 113 to block the second insertion port 113; the locking portion 32 passes through the second insertion port 113 and abuts against the abutment portion 12 to prevent deformation of the abutment portion 12.

[0041] During the installation of the female terminal 2, the abutment portion 12 undergoes elastic deformation to allow the female terminal 2 to enter the mounting cavity. After the female terminal 2 is installed in place, the abutment portion 12 needs to maintain abutting force on the female terminal 2 to prevent it from moving backward. If the abutment portion 12 deforms unexpectedly due to long-term stress or external vibration, it may cause the constraint on the female terminal 2 to fail. The locking portion 32 of the front cover 3 abuts against the abutment portion 12, which can limit the deformation space of the abutment portion 12 and ensure that the abutment portion 12 always maintains stable contact with the female terminal 2, thereby further improving the firmness of the installation of the female terminal 2. The setting of the second socket 113 creates conditions for the locking portion 32 to enter the mounting cavity of the housing body 11, and the cover body 31 abuts against the edge of the second socket 113 to close the second socket 113, preventing external dust, impurities, etc. from entering the mounting cavity through the second socket 113, thereby affecting the normal operation or electrical connection performance of the female terminal 2.

[0042] In some embodiments, please refer to Figure 2 , Figure 3 and Figure 4 To improve the compactness and aesthetics of the structure, the assembly relationship between the front ends of the cover body 31 and the shell body 11 was optimized. Specifically, the edge of the second socket 113 is recessed towards the rear of the first shell 1 so that the front end face of the cover body 31 is flush with the front end face of the shell body 11.

[0043] The edge of the second socket 113 forms a stepped recessed area. When the cover body 31 abuts against this edge, the front end face of the cover body 31 is flush with the front end face of the shell body 11. This flush design not only makes the overall appearance of the first connecting component 100 of the connector flatter and simpler, improving the aesthetics of the product, but also reduces the protruding structure on the front end face of the first connecting component 100, lowering the risk of the cover body 31 becoming loose due to collision or snagging during use. At the same time, the flat front end face also facilitates the first connecting component 100 to fit snugly with other components during installation or use, enhancing the compactness of the structure and space utilization.

[0044] In some embodiments, please refer to Figure 3 and Figure 5 In order to reduce injection molding deformation, a number of stress relief holes 311 are provided on the edge and / or inner area of ​​the cover body 31, and the stress relief holes 311 are spaced apart.

[0045] The stress relief holes 311 are designed to disperse the internal stress generated during the injection molding process of the cover body 31 by cooling and shrinking the material. This prevents the cover body 31 from warping, cracking, or other deformation problems caused by stress concentration, thus ensuring the fitting accuracy between the cover body 31 and the edge of the second socket 113, guaranteeing its sealing effect on the second socket 113 and its flushness with the front end face of the shell body 11. The spaced stress relief holes 311 also enable lightweight design without significantly reducing the structural strength of the cover body 31. Furthermore, they provide a buffer space for external forces that the cover body 31 may experience during assembly or use, further improving the overall structural stability and service life of the front cover 3.

[0046] Of course, since the stress relief hole 311 is filled by the mold during injection molding, the hole position of the first stress relief hole 311 can also be understood as a molding space reserved during mold design. Furthermore, the front end face of the shell body 11 also has a mold reserved position at the location of the stress relief hole 311, so the mold layout position of the shell body 11 is consistent with the mold layout position of the cover body 31. This consistency allows some of the molds for injection molding the first shell 1 and the front cover 3 to be shared, thereby effectively reducing mold development costs and management complexity, while ensuring the positional accuracy of the first shell 1 and the front cover 3 during assembly, reducing assembly deviations caused by mold differences, and improving product production efficiency and pass rate.

[0047] In some embodiments, please refer to Figure 3 and Figure 5In order to securely position the front cover 3 on the front end face of the shell body 11, a surrounding frame 33 is added to the front cover 3. Specifically, the surrounding frame 33 surrounds the outer periphery of the front end face of the shell body 11; the cover body 31 is located within the inner area of ​​the surrounding frame 33.

[0048] The frame 33 provides a surrounding restraint on the cover body 31 from the outer periphery of the front end face of the shell body 11, effectively preventing the cover body 31 from shifting or shaking in the horizontal direction. When the cover body 31 is installed at the front end of the shell body 11, the inner wall of the frame 33 fits snugly against the outer wall of the cover body 31, further enhancing the tightness of the connection between the front cover 31 and the shell body 11. Simultaneously, the frame 33 also protects the edges of the cover body 31, reducing the direct impact of external collisions on the edges of the cover body 31, thereby reducing the possibility of the cover body 31 becoming loose due to edge damage.

[0049] In some embodiments, please refer to Figure 5 and Figure 6 In order to fix the front cover 3 to the shell body 11, a first snap-fit ​​structure 34 is added to the locking part 32, and correspondingly, a second snap-fit ​​structure 114 is added to the inner wall of the shell body 11. Furthermore, the first snap-fit ​​structure 34 snaps into the second snap-fit ​​structure 114 to prevent the locking part 32 from moving in the front-back direction.

[0050] The first locking structure 34 and the second locking structure 114 cooperate to form a mechanical lock in the front-to-back direction, further restricting the locking part 32 from disengaging from the second insertion port 113. The first locking structure 34 and the second locking structure 114 can be formed in several ways: First, the first locking structure 34 is a protrusion on the outer peripheral surface of the locking part 32, and the second locking structure 114 is a groove on the inner wall of the shell body 11, with the protrusion and groove fitting and engaging; Second, the first locking structure 34 is a slot on the locking part 32, and the second locking structure 114 is a buckle on the inner wall of the shell body 11, with the buckle engaging with the slot; Third, both the first locking structure 34 and the second locking structure 114 are mutually cooperating barbed structures, achieving engagement through the hooking action of the barbs. Regardless of the snap-fit ​​method used, its core function is to enhance the connection strength between the locking part 32 and the housing body 11, ensuring that the locking part 32 can continuously and stably abut against the abutment part 12, thereby indirectly ensuring the constraint effect of the abutment part 12 on the female terminal 2. This snap-fit ​​structure design makes the installation and removal of the front cover 3 convenient, and at the same time provides reliable connection stability after assembly, preventing the front cover 3 from moving in the front-to-back direction due to vibration or external force during use, thus ensuring the overall structural stability of the connector.

[0051] In some embodiments, please refer to Figure 5 and Figure 6The first snap-fit ​​structure 34 adopts an elastic snap-fit ​​protrusion 341, and the second snap-fit ​​structure 114 adopts a snap-fit ​​platform 1141. Furthermore, the elastic snap-fit ​​protrusion 341 is designed to protrude outward from the mounting cavity, and the snap-fit ​​platform 1141 is designed to protrude inward from the mounting cavity, with the snap-fit ​​protrusion snapping into the rear side of the snap-fit ​​platform 1141.

[0052] The elastic protrusion 341 has a certain elastic deformation capability. During the process of the locking part 32 passing through the second insertion port 113 into the mounting cavity, the elastic protrusion 341 contacts and deforms against the inner wall of the housing body 11 or the front end face of the locking platform 1141, thus smoothly passing through the position of the locking platform 1141. Once the locking part 32 is fully inserted, the elastic protrusion 341 is no longer compressed, returns to its original shape, and engages with the rear side of the locking platform 1141. At this time, the locking platform 1141 forms a forward obstruction against the elastic protrusion 341, effectively preventing the locking part 32 from moving backward. This design utilizes the elastic characteristics of the elastic protrusion 341 to achieve convenient engagement, while the rear abutment surface of the locking platform 1141 provides a stable limiting effect, ensuring a secure and reliable connection between the locking part 32 and the housing body 11. In addition, the engagement structure between the elastic protrusion 341 and the mounting plate 1141 is simple and easy to manufacture, which can reduce the difficulty and cost of production process. At the same time, when it is necessary to remove the front cover 3, a certain external force can be applied to deform the elastic protrusion 341, thereby releasing the engagement relationship with the mounting plate 1141, which facilitates the maintenance or replacement of the internal structure of the first connection component 100 of the connector.

[0053] In some embodiments, please refer to Figure 3 and Figure 4 To prevent water or other liquids from seeping into the mounting cavity through the gap between the front cover 3 and the shell body 11, a first sealing element 4 is added. In order to position the first sealing element 4, an annular protrusion 115 is formed on the outer wall surface of the shell body 11. The first sealing element 4 is sleeved on the periphery of the shell body 11 and abuts between the annular protrusion 115 and the cover body 31.

[0054] The first sealing element 4 can be made of elastic and sealing materials such as rubber or silicone, and has a ring-shaped structure. An annular protrusion 115 surrounds the outer circumference of the housing body 11, protruding towards the front of the first housing 1, providing a clear installation reference for the first sealing element 4. When the first sealing element 4 is fitted around the outer periphery of the housing body 11 and abuts against the annular protrusion 115 and the cover body 31, the annular protrusion 115 provides support to the rear side of the first sealing element 4, while the rear side of the cover body 31 applies pressure to the front side of the first sealing element 4, causing the first sealing element 4 to undergo elastic deformation due to compression in the front-rear direction. This deformation fills the gap between the cover body 31 and the outer wall of the housing body 11, forming a continuous sealing barrier that effectively prevents external liquids, moisture, dust, and other impurities from entering the mounting cavity of the housing body 11 through this gap. This improved sealing performance further ensures the electrical connection reliability and service life of the female terminal 2.

[0055] Similarly, please see Figure 2 To achieve a seal at the rear end of the housing body 11, a second sealing element 5 is added. Specifically, the rear end of the housing body 11 forms a mounting port for inserting the female terminal 2. The second sealing element 5 is disposed at the mounting port to seal the gap between the mounting port and the female terminal 2. The second sealing element 5 can be made of the same or similar elastic sealing material as the first sealing element 4, and its shape is adapted to the outer periphery of the mounting port and the female terminal 2. When the female terminal 2 is inserted into the mounting port at the rear end of the housing body 11 and installed in place, the second sealing element 5 is pressed between the inner wall of the mounting port and the outer wall of the female terminal 2, filling the gap between them through its own elastic deformation, thereby preventing external liquids, moisture, or dust from entering the mounting cavity through the mounting port. This design, in conjunction with the first sealing element 4 at the front end, forms a double sealing protection for both ends of the housing body 11, further improving the overall sealing level of the connector, ensuring stable electrical connection performance in relatively humid or dusty environments, and extending the product's service life. Meanwhile, the installation of the second sealing element 5 will not affect the normal installation and disassembly of the female terminal 2. While ensuring the sealing effect, it also takes into account the practicality of the structure and the convenience of assembly.

[0056] Please see Figure 1The connector also includes a second connecting component 200 adapted to the first connecting component 100. The second connecting component 200 includes a male housing and a male terminal disposed within the male housing. The male terminal corresponds to the female terminal 2 of the miniature waterproof first connecting component 100 for automotive mirrors. When the male housing of the second connecting component 200 is inserted into the first housing 1 of the miniature waterproof first connecting component 100 for automotive mirrors, the male terminal is electrically connected to the female terminal 2 via the first insertion port 111 of the first housing 1. The first housing 1 of the miniature waterproof first connecting component 100 for automotive mirrors and the male housing of the second connecting component 200 can be detachably connected by means of snaps, threads, or magnetic attraction to ensure connection stability during use. By adopting the aforementioned miniature waterproof first connecting component 100 for automotive mirrors with a dual-limiting structure, this connector effectively reduces the risk of the female terminal 2 detaching, improves the overall reliability of the electrical connection, and further enhances the structural stability, sealing performance, and service life of the connector through the optimized front cover 3 design and sealing structure.
