Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to a spring-type contact waterproof connector. Background Art

[0002] In the field of connector technology, spring-type terminals are widely used in various electronic devices due to their unique elastic contact properties. They operate by leveraging the elastic deformation of the spring to achieve a reliable electrical connection with the mating component after assembly. This connection can accommodate a certain degree of vibration and displacement, ensuring stable signal transmission.

[0003] Current spring-type waterproof connectors utilize an integrated spring terminal bent 90 degrees, with a pin end on one end and a spring end for connecting to the panel. During assembly, the pin end is inserted vertically into the housing from the rear end. While this vertical insertion ensures effective connection between the spring terminal, the housing, and the external panel, it creates a difficult-to-fill gap at the rear end, making conventional sealing methods difficult. Traditional sealing materials, such as rubber rings and waterproof tape, cannot achieve a tight fit and effective seal due to the complex structure of the rear end and the interference of the spring terminal. Furthermore, after the spring terminal is inserted, when the rear end of the housing is subjected to secondary waterproofing, existing waterproofing processes, such as potting and coating, fail to create a sealed space, resulting in blind spots and potential safety hazards during future use. Furthermore, existing waterproofing processes require extremely high precision in the housing structure. Any deviation not only compromises the electrical connection stability of the spring terminal but also further exacerbates the gap problem at the rear end, making waterproofing even more challenging. Therefore, solving the waterproof problem of spring contact terminals is of great significance for improving the performance and reliability of electronic equipment in complex environments.

Furthermore, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0043] It should also be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections or electrical connections; they may refer to direct connections or connections through an intermediate medium; and they may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0044] See also Figure 1 Current spring-type waterproof connectors utilize an integrated spring terminal 101, bent 90 degrees, with a pin end 1011 at one end and a spring end 1012 at the other for connecting to the panel 300. During assembly, the pin end 1011 is vertically inserted into the housing 102 from the rear end. While this vertical insertion ensures effective connection between the spring terminal 101, the housing 102, and the external panel 300, it creates a difficult-to-fill gap at the rear end of the housing 102, making it difficult to seal using conventional sealing methods.

[0045] Based on this, see Figure 2-6 The embodiment of the present application provides a spring contact waterproof connector, including: a male socket 20 and a female socket 10 that are plugged into each other; one end of the male socket 20 is plugged into the female socket 10, and the other end is connected to the external panel 300.

[0046] See also Figure 3 、 Figure 5 and Figure 6 Specifically, the male socket 20 includes a male socket shell 23 and a terminal group fixed inside the male socket shell 23; the male socket shell 23 is provided with a first cavity 231 and a second cavity 232 vertically connected; the first cavity 231 is sealed and plugged into the female socket 10, and the end of the second cavity 232 away from the first cavity 231 is sealed and connected to the panel 300.

[0047] Furthermore, the terminal group includes a first terminal 21 and a second terminal 22, the first terminal 21 is fixed in the first cavity 231, and one end of the first terminal 21 is separated between the first cavity 231 and the second cavity 232; one end of the second terminal 22 is inserted into the second cavity 232 and is conductively connected to the first terminal 21; the other end of the second terminal 22 is elastically conductively connected to the panel 300.

[0048] It will be appreciated that, in this arrangement, a first plug port 2311 is provided at one end of the first chamber 231, and the other end is connected to the second chamber 232. A second plug port 2321 is provided at the end of the second chamber 232 remote from the first chamber 231. The first plug port 2311 is sealedly plugged into the female connector 10, and the second plug port 2321 is sealedly abutted against the panel 300, achieving a completely sealed connection with the male connector housing 23. In this manner, the first terminal 21 and the male connector housing 23 are integrally injection molded, and the second terminal 22 is then inserted into the second chamber 232 via the second plug port 2321 and connected to the first terminal 21. This simplifies the overall assembly process, simplifies the design of the overall connector waterproof structure, eliminates the need for complex waterproofing post-processing, and improves product stability.

[0049] The spring contact waterproof connector provided in the embodiment of the present application is configured with a split terminal group and an integrated sealed male socket shell 23, and the first terminal 21 is fixed in the first chamber 231 and formed integrally with the male socket shell 23. The male socket 20 can be assembled by simply inserting the second terminal 22 into the male socket shell 23 and fixing it with the first terminal 21. The structure is simple and the waterproof performance of the connector can be easily achieved.

[0050] See also Figure 3 、 Figure 5 and Figure 6 Furthermore, in some embodiments, the first terminal 21 includes a pin portion 211 and a fixed portion 212. The pin portion 211 is plugged into the female connector 10, and the edge of the fixed portion 212 is embedded in the inner wall of the first cavity 231 and is located between the first cavity 231 and the second cavity 232. This arrangement facilitates the mold design of the male connector housing 23 and facilitates demolding during injection molding of the male connector housing 23.

[0051] In this embodiment, the two first terminals 21 are symmetrically arranged at intervals, and a partition 2312 is provided at one end of the first chamber 231 close to the second chamber 232 to separate the two fixing portions 212 to prevent electrical faults such as short circuits; at the same time, it can also increase the holding force of the fixing portions 212 to avoid deformation or damage of the fixing portions 212 due to the plugging and unplugging force from the pin portion 211 and the second terminal 22, thereby affecting the electrical connection stability of the male socket 20.

[0052] Furthermore, in some embodiments, the two fixing portions 212 extend outward relative to the pin portion 211 to increase the contact space between the first terminal 21 and the second terminal 22, thereby facilitating the connection between the second terminal 22 and the first terminal 21. The end of the pin portion 211 closest to the fixing portion 212 is embedded within the spacer 2312, thereby increasing the stability of the pin portion 211 through the injection-molded spacer 2312.

[0053] See also Figure 7-13 Furthermore, in some embodiments, a first spring piece 221 is provided at one end of the second terminal 22 for elastically connecting with the first terminal 21, and a second spring piece 222 is provided at the other end for elastically connecting with the panel. Specifically, the first spring piece 221 includes a first abutting portion 2211 and / or a first plug-in portion 2212, which elastically abuts with the first terminal 21.

[0054] See also Figure 9-13 Furthermore, in some embodiments, the first spring piece 221 is provided with a first plug-in portion 2212. As a match, the first terminal 21 is provided with a plug-in hole 2121, which is provided in the fixing portion 212. The first plug-in portion 2212 is inserted into the plug-in hole 2121 and elastically abuts against the edge of the plug-in hole 2121.

[0055] See also Figure 9 and Figure 10 In some embodiments, the first plug-in portion 2212 has a strip-like structure, comprising a plurality of plug-in segments 2213 extending along the length of the second terminal 22 and curved in a wavy shape. The plug-in segments 2213 at the ends elastically abut against the plug-in hole 2121. In this embodiment, the first plug-in portion 2212 includes two plug-in segments 2213, one end of which is connected at a certain angle. The connected ends of the two plug-in segments 2213 are inserted into the plug-in hole 2121. As they are inserted, the other ends of the two plug-in segments 2213 are gradually elastically squeezed by the plug-in hole 2121 and moved closer together, thereby elastically connecting with the plug-in hole 2121. In this configuration, the plug-in hole 2121 is preferably a square hole, which facilitates stable contact between the plug-in hole 2121 and the strip-shaped first plug-in portion 2212.

[0056] See also Figure 11 and Figure 12 In some other embodiments, the first plug-in portion 2212 is a circular structure, which includes a plurality of plug-in segments 2213 extending along the width direction of the second terminal 22 and bent into an arc shape, and the plurality of plug-in segments 2213 are elastically abutted against the plug-in hole 2121.

[0057] As a specific embodiment, the first inserting part 2212 comprises two arc-shaped inserting segments 2213, one end of the two arc-shaped inserting segments 2213 is connected, and the axial direction of the arc-shaped inserting segments 2213 is parallel to the inserting direction. The free ends of the two inserting segments 2213 are spaced apart by a certain distance to leave a space for elastic deformation. When the first inserting part 2212 is pressed, the free ends of the two inserting segments 2213 move towards each other, and the radius of the inserting segments 2213 gradually decreases, thereby stably and elastically connecting with the inserting hole 2121. In this arrangement, the inserting hole 2121 is preferably a circular hole, which facilitates stable contact with the first inserting part 2212 in a circular structure. Further, in this arrangement, the inserting end of the inserting segment 2213 is also provided with a guide-in part bent by a certain angle towards the axial center, which facilitates smooth insertion of the inserting segment 2213 into the inserting hole 2121, which will not be described in detail here.

[0058] Please refer to Figure 12 and Figure 13 As another specific embodiment, the first inserting part 2212 comprises a plurality of arc-shaped inserting segments 2213 protruding from the middle, and the axial direction of the arc-shaped inserting segments 2213 is perpendicular to the inserting direction. The plurality of arc-shaped inserting segments 2213 are spaced apart to form a circular structure and elastically abut against the inserting hole 2121.

[0059] Please refer to Figure 7 and Figure 8 Further, in some embodiments, the first elastic sheet 221 is also provided with a first abutting part 2211 which elastically abuts against the end surface of the first terminal 21 facing the second cavity 232. Specifically, the first abutting part 2211 is a spring arm bent by a certain arc. With the insertion of the second terminal 22, the first abutting part 2211 is pressed and slides relative to the fixed part 212 and is elastically compressed, thereby achieving elastic abutment with the first terminal 21. It can be understood that the first abutting part 2211 can be one or more, and can be bent in the same direction or in the opposite direction, thereby achieving elastic connection with the first terminal 21, and also serving to support the second elastic sheet 222, thereby ensuring the stability of the contact between the second elastic sheet 222 and the panel 300. In some other embodiments, the first abutting part 2211 can also be a spring arm structure with other shapes of fixed contacts, without being limited thereto.

[0060] It should be noted that the first elastic sheet 221 can be elastically connected with the first terminal 21 through the first abutting part 2211, or can be elastically connected with the first terminal 21 through the first inserting part 2212, or can be elastically connected with the first terminal 21 through both the first abutting part 2211 and the first inserting part 2212, without being limited thereto.

[0061] Please refer to Figure 6 , Figure 14 and Figure 15Furthermore, in some embodiments, the plug-in hole 2121 is provided with a flange structure 2122 bent toward the second chamber 232, which is used to guide the first plug-in portion 2212 during insertion, so as to facilitate the smooth insertion of the first plug-in portion 2212 into the plug-in hole 2121. At the same time, it can increase the contact points of the first terminal 21 and the second terminal 22 for plugging, thereby improving the stability of its electrical connection.

[0062] In a specific embodiment, the flange structure 2122 is an arc-shaped flange protruding toward the center of the insertion hole 2121, elastically abutting the insertion section 2213. With this arrangement, the flange structure 2122 is open. When the second terminal 22 is assembled, the first insertion portion 2212 first elastically abuts the arc-shaped flange. The elastic force of the arc-shaped flange squeezes the first insertion portion 2212 toward the center, causing the multiple insertion sections 2213 to elastically deform and move closer together, allowing for smooth insertion into the insertion hole 2121 and stable elastic contact with the edge of the insertion hole 2121. Simultaneously, the arc-shaped flange also elastically abuts the insertion sections 2213, increasing the number of contact points and contact area between the first terminal 21 and the second terminal 22, improving the stability of the insertion connection between the first terminal 21 and the second terminal 22, and also accommodating high-current applications.

[0063] See also Figure 6 and Figure 7 Furthermore, in some embodiments, the second spring piece 222 is provided with a second abutting portion 2221 and a plurality of elastic support portions 2222. The elastic support portion 2222 and the second abutting portion 2221 are bent at a certain angle. The elastic support portion 2222 is compressed and deformed to provide elastic force to the second abutting portion 2221 to ensure that the second abutting portion 2221 is in stable contact with the panel 300; at the same time, the floating connection between the second spring piece 222 and the panel can be guaranteed, and poor connection caused by inaccurate positioning between the second spring piece 222 and the panel can be avoided, thereby ensuring the stability of the connection between the second spring piece 222 and the panel.

[0064] Furthermore, in some embodiments, the second terminal 22 is further provided with a snap-fit ​​portion 223. The snap-fit ​​portion 223 is disposed between the first elastic piece 221 and the second elastic piece 222, and a snap-fit ​​structure 2231 is provided along one or both sides of the second terminal 22 in its width direction. In coordination, a snap-fit ​​groove 2322 is provided on the inner wall of the second cavity 232, and the snap-fit ​​structure 2231 is fixedly connected to the snap-fit ​​groove 2322. When installing the second terminal 22, the snap-fit ​​portion 223 is inserted into the snap-fit ​​groove 2322 and then inserted along the snap-fit ​​groove 2322 toward the first terminal 21. The snap-fit ​​structure 2231 interferes with and secures the inner wall of the snap-fit ​​groove 2322, thereby securing the second terminal 22 within the second cavity 232 and ensuring stable conductive connection between the second terminal 22 and the first terminal 21 and the panel 300, respectively.

[0065] Furthermore, in some embodiments, the snap-fit ​​groove 2322 extends upward along the inner wall of the second chamber 232 until it abuts against the fixing portion 212 , which can further support the fixing portion 212 and further prevent the fixing portion 212 from being deformed by force and affecting the connection between the first terminal 21 and the second terminal 22 .

[0066] Furthermore, in some embodiments, the second terminal 22 is further provided with a connecting portion 224. This connecting portion 224 extends and connects to the clamping portion 223 and is located on one or both sides of the second spring clip 222 for connecting to the strip. Furthermore, the connecting portion 224 is completely located within the second cavity 232 to prevent interference with the panel. This ensures that the first spring clip 221 is properly inserted and maintains a stable conductive connection with the first terminal 21. Furthermore, the connecting portion 224 can also limit the movement of the second spring clip 222 to prevent excessive force on the second spring clip 222, resulting in elastic fatigue and thus affecting its stable contact with the panel. This will not be described in detail here.

[0067] See also Figure 2-4 Furthermore, in some embodiments, the male connector 20 or the female connector 10 is provided with a first sealing member 13 to achieve a sealed connection between the male connector 20 and the female connector 10. In this embodiment, the female connector 10 is provided with a plug connector 11 that is inserted into the first cavity 231 via the first plug port 2311 and electrically connected to the first terminal 21. The outer wall of the plug connector 11 is provided with a first sealing groove 12. The first sealing member 13 is located within the first sealing groove 12 and seals against the inner wall of the first cavity 231, achieving a sealed connection on one side of the first plug port 2311. This achieves a sealed connection between the male connector 20 and the female connector 10.

[0068] Furthermore, a second sealing groove 2323 is provided at the end of the second chamber 232 close to the panel 300, and the second sealing groove 2323 is provided with a second sealing member 2324. When the male socket shell 23 is fixed to the panel 300, the second sealing member 2324 is sealed against the panel 300 to achieve sealing on one side of the second plug port 2321. This can ensure the waterproof connection between the male socket 20 and the female socket 10 and the panel 300 respectively, thereby realizing waterproof installation of the connector.

[0069] Further, in some embodiments, the outer wall of the second chamber 232 is provided with a positioning portion 233 extending to both sides, which is fixedly connected to the panel 300. It can be understood that the positioning portion 233 can be fixedly connected to the panel 300 by a locking member 2332 or other fixed connection structure. In the present embodiment, the positioning portion 233 is provided with a positioning hole 2331, and the panel 300 is correspondingly provided with a locking hole 301, and the locking member 2332 passes through the positioning hole 2331 and is locked and connected with the locking hole 301, so as to realize the fixed connection of the male seat 20 and the panel 300. In this way, the dislocation of the second terminal 22 and the panel 300 caused by environmental vibration during use of the connector can be avoided, thereby affecting the stable connection of the two.

[0070] Please refer to Figure 4 Further, in some embodiments, the female seat 10 and the male seat 20 are connected by a buckle structure to avoid the disconnection of the female seat 10 and the male seat 20 in a force or vibration environment, thereby causing unstable electrical connection of the connector. As an example, the female seat 10 is provided with a spring arm hook 14, and the male seat 20 is provided with a buckle position 2313. Specifically, the buckle position 2313 is arranged on the outer wall of the first chamber 231. When the plug 11 of the female seat 10 is inserted into the first chamber 231, the spring arm hook 14 located outside the first chamber 231 is buckled with the buckle position 2313, thereby realizing the buckling connection of the male seat 20 and the female seat 10.

[0071] Further, in some embodiments, the inside of the first chamber 231 and the plug 11 of the female seat 10 are provided with matched guide grooves and guide rib positions, which are used for positioning and guiding when the plug 11 of the female seat 10 is inserted into the first chamber 231, which will not be described in detail here.

[0072] Compared with the prior art, the elastic sheet contact type waterproof connector provided by the present application has the following advantages:

[0073] (1) Based on the elastic sheet contact, the rigid insertion of the male seat and the female seat and the elastic connection with the panel are realized by arranging a split type terminal group. The first terminal is integrally formed with the male seat shell. During assembly, the elastic sheet type second terminal is only inserted into the inside of the male seat shell to be connected with the first terminal, which is easy to assemble.

[0074] (2) The male seat shell is integrally arranged and only provided with a first insertion port and a second insertion port, which are respectively sealed with the female seat and the panel to realize waterproof connection. The male seat shell structure is simple and does not need complex waterproof post-processing technology.

[0075] (3) A first spring is provided at one end of the second terminal to be elastically connected to the first terminal, and a second spring is provided at the other end to be elastically connected to the panel, which can reduce the precision requirements of the male socket housing, reduce the elastic fatigue of the second terminal, and improve the electrical connection stability of the connector.

[0076] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous modifications and improvements without departing from the spirit of the present invention, and the present invention is intended to encompass such modifications and variations.
