Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and particularly to a shrapnel contact waterproof connector. Background Art

[0002] In the technical field of connectors, shrapnel contact terminals are widely used in various electronic devices due to their unique elastic contact characteristics. Its working principle is to utilize the elastic deformation of the shrapnel to achieve a reliable electrical connection with the docking component after assembly. This connection method can adapt to a certain degree of vibration and displacement, ensuring the stability of signal transmission. The current shrapnel waterproof connector adopts an integrated shrapnel terminal, which is bent at 90 degrees. One end is the pin end, and the other end is the shrapnel end for conducting connection with the panel. When assembling the shrapnel terminal, its pin end is vertically inserted into the plastic housing from the tail of the plastic housing. Although this vertical insertion method can ensure the effective connection between the shrapnel terminal and the plastic housing and the external panel, it leaves a gap hidden danger at the tail of the plastic housing that is difficult to fill, making it difficult to apply conventional sealing means at the tail of the plastic housing. Traditional sealing materials such as sealing rubber rings and waterproof tapes cannot achieve tight fitting and effective sealing under the interference of the complex structure at the tail of the plastic housing and the shrapnel terminal. Moreover, when performing secondary waterproof treatment on the tail of the plastic housing after inserting the shrapnel terminal, existing waterproof processes such as potting and coating cannot form a sealed space, easily resulting in waterproof blind spots and posing potential safety hazards for future use. In addition, the existing waterproof process has very high requirements for the accuracy of the plastic housing structure. Once there is a deviation, it will not only affect the electrical connection stability of the shrapnel terminal, but also further exacerbate the gap problem at the tail of the plastic housing, making the waterproof treatment even more difficult. Therefore, solving the waterproof problem of shrapnel contact terminals is of great significance for improving the performance and reliability of electronic devices in complex environments.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] Please refer to Figure 1 , currently, the elastic sheet type waterproof connector adopts an integral elastic sheet terminal 101, which is bent at 90 degrees. One end is the pin end 1011, and the other end is the elastic sheet end 1012, which is used for conducting connection with the panel 300. When assembling the elastic sheet terminal 101, its pin end 1011 is vertically inserted into the tail of the plastic housing 102 from the tail of the plastic housing 102. Although this vertical insertion method can ensure the effective connection between the elastic sheet terminal 101, the plastic housing 102, and the external panel 300, it leaves a hidden danger of a gap that is difficult to fill at the tail of the plastic housing 102, making it difficult to seal the tail of the plastic housing 102 by conventional sealing means.

[0022] Based on this, please refer to Figure 2-6 , an embodiment of the present application provides an elastic sheet contact type waterproof connector, including: a male seat 20 and a female seat 10 that are inserted into each other; one end of the male seat 20 is inserted into the female seat 10, and the other end is conductively connected to the external panel 300.

[0023] Please refer to Figure 3 , Figure 5 and Figure 6 , specifically, the male seat 20 includes a male seat housing 23 and a terminal group fixedly arranged inside the male seat housing 23; the male seat housing 23 is provided with a first chamber 231 and a second chamber 232 that are vertically connected; the first chamber 231 is hermetically inserted into the female seat 10, and one end of the second chamber 232 away from the first chamber 231 is hermetically connected to the panel 300.

[0024] Furthermore, the terminal group includes a first terminal 21 and a second terminal 22. The first terminal 21 is fixedly arranged in the first chamber 231, and one end of it is separated between the first chamber 231 and the second chamber 232; one end of the second terminal 22 is inserted into the second chamber 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.

[0025] It can be understood that in this setting method, one end of the first chamber 231 is provided with a first plug port 2311, the other end is connected to the second chamber 232, the end of the second chamber 232 away from the first chamber 231 is provided with a second plug port 2321, the first plug port 2311 is hermetically plugged into the female seat 10, and the second plug port 2321 is hermetically abutted against the panel 300, realizing the completely sealed connection of the male seat housing 23. In this way, the first terminal 21 and the male seat housing 23 are integrally injection-molded, and then the second terminal 22 is inserted into the second chamber 232 through the second plug port 2321 and conductively connected to the first terminal 21. The overall assembly process is simple, the design of the waterproof structure of the overall connector can be simplified, and complex waterproof post-treatment processes are not required, improving the stability of the product.

[0026] The elastic contact waterproof connector provided by the embodiment of the present application, by setting a split terminal group and an integral sealed male seat housing 23, fixes the first terminal 21 in the first chamber 231 and is integrally formed with the male seat housing 23. Only by inserting the second terminal 22 into the male seat housing 23 and fixedly conducting it with the first terminal 21, the assembly of the male seat 20 can be completed. The structure is simple and the waterproof performance of the connector can be easily realized.

[0027] Please refer to Figure 3 、 Figure 5 and Figure 6 Further, in some embodiments, the first terminal 21 includes a pin portion 211 and a fixing portion 212. The pin portion 211 is plugged into the female seat 10, and the edge of the fixing portion 212 is embedded in the inner wall of the first chamber 231 and separated between the first chamber 231 and the second chamber 232. In this setting method, it is beneficial to the mold design of the male seat housing 23 and facilitates the demolding when the male seat housing 23 is injection-molded.

[0028] In this embodiment, the two first terminals 21 are symmetrically arranged at intervals. A separator 2312 is provided at one end of the first chamber 231 close to the second chamber 232 to separate the two fixing portions 212 and prevent electrical defects such as short circuits; at the same time, it can also increase the holding force on the fixing portion 212 to avoid deformation or damage of the fixing portion 212 caused by the insertion and extraction forces from the pin portion 211 and the second terminal 22, thereby affecting the electrical connection stability of the male seat 20.

[0029] Further, 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, facilitating the conductive connection between the second terminal 22 and the first terminal 21. One end of the pin portion 211 close to the fixing portion 212 is embedded inside the separator 2312 to increase the stability of the pin portion 211 through the injection-molded separator 2312.

[0030] Please refer to Figure 7-13, Further, in some embodiments, one end of the second terminal 22 is provided with a first elastic piece 221 for elastic conduction connection with the first terminal 21, and the other end is provided with a second elastic piece 222 for elastic conduction connection with the panel. Specifically, the first elastic piece 221 includes a first abutting portion 2211 and / or a first insertion portion 2212, and elastically abuts against the first terminal 21.

[0031] Please refer to Figure 9-13 , Further, in some embodiments, the first elastic piece 221 is provided with a first insertion portion 2212. Correspondingly, the first terminal 21 is provided with an insertion hole position 2121, and the insertion hole position 2121 is arranged on the fixing portion 212. The first insertion portion 2212 is inserted into the insertion hole position 2121 and elastically abuts against the edge of the insertion hole position 2121.

[0032] Please refer to Figure 9 and Figure 10 , In some embodiments, the first insertion portion 2212 has a strip-like structure, which includes a plurality of insertion segments 2213 that extend along the length direction of the second terminal 22 and are bent into a wavy shape. The insertion segments 2213 at the end are elastically abutted against the insertion hole position 2121. In this embodiment, the first insertion portion 2212 includes two insertion segments 2213. One ends of the two insertion segments 2213 are connected at a certain angle. The connected ends of the two insertion segments 2213 are inserted into the insertion hole position 2121. As they are inserted, the other ends of the two insertion segments 2213 are gradually elastically squeezed by the insertion hole position 2121 and approach each other, and are elastically conductively connected to the insertion hole position 2121. In this setting method, the insertion hole position 2121 is preferably a square hole, which is convenient for the insertion hole position 2121 to stably contact with the strip-like first insertion portion 2212.

[0033] Please refer to Figure 11 and Figure 12 , In some other embodiments, the first insertion portion 2212 has a round-enclosing structure, which includes a plurality of insertion segments 2213 that extend along the width direction of the second terminal 22 and are bent into an arc shape. The plurality of insertion segments 2213 are all elastically abutted against the insertion hole position 2121.

[0034] As a specific embodiment, the first plugging portion 2212 includes two arc-shaped plugging segments 2213. One ends of the two arc-shaped plugging segments 2213 are connected, and the axial direction of the arc-shaped plugging segments 2213 is parallel to the plugging direction. Free ends of the two plugging segments 2213 are spaced apart by a certain distance to leave an elastic deformation space. When the first plugging portion 2212 is squeezed, the free ends of the two plugging segments 2213 approach each other, and the radius of the plugging segments 2213 gradually becomes smaller, so as to stably and elastically conduct with the plugging hole position 2121. In this setting mode, the plugging hole position 2121 is preferably a circular hole, which is convenient for stable contact with the first plugging portion 2212 with a circumferential structure. Further, in this setting mode, an introducing portion bent at a certain angle toward the axis is further provided at the inserting end of the plugging segment 2213, which is convenient for the plugging segment 2213 to be smoothly inserted into the plugging hole position 2121, and details are not described herein.

[0035] Please refer to Figure 12 and Figure 13 As another specific embodiment, the first plugging portion 2212 includes a plurality of arc-shaped plugging segments 2213 protruding in the middle, and the axial direction of the arc-shaped plugging segments 2213 is perpendicular to the plugging direction. The plurality of arc-shaped plugging segments 2213 are spaced apart and surrounded to form a circumferential structure, which elastically abuts against the plugging hole position 2121.

[0036] Please refer to Figure 7 and Figure 8 Further, in some embodiments, the first elastic piece 221 is further provided with a first abutting portion 2211, and the first abutting portion 2211 elastically abuts against the end face of the first terminal 21 facing the second chamber 232. Specifically, the first abutting portion 2211 is an elastic arm bent into a certain arc. As the second terminal 22 is inserted, the first abutting portion 2211 slides relative to the fixing portion 212 under pressure and is elastically squeezed to achieve elastic abutment with the first terminal 21. It can be understood that the first abutting portion 2211 can be one or more, and can also be bent in the same direction or in the opposite direction to achieve elastic conduction with the first terminal 21, and can also play a role in supporting the second elastic piece 222 to ensure the contact stability between the second elastic piece 222 and the panel 300. In some other embodiments, the first abutting portion 2211 can also be an elastic arm structure with a fixed contact point in other shapes, and is not limited thereto.

[0037] It should be noted that the first elastic piece 221 can be elastically conducted with the first terminal 21 through the first abutting portion 2211, or can be elastically conducted with the first terminal 21 by setting the first plugging portion 2212, or can also set the first abutting portion 2211 and the first plugging portion 2212 together to elastically conduct with the first terminal 21, and is not limited thereto.

[0038] Please refer to Figure 6 、 Figure 14 and Figure 15, Further, in some embodiments, the insertion hole 2121 is provided with a flanging structure 2122 that bends toward the second chamber 232, which is used for guiding when the first insertion part 2212 is inserted, facilitating the smooth insertion of the first insertion part 2212 into the insertion hole 2121. At the same time, it can increase the contact points of the insertion between the first terminal 21 and the second terminal 22, improving the stability of their electrical connection.

[0039] As a specific implementation manner, the flanging structure 2122 is an arc-shaped flanging that protrudes toward the middle of the insertion hole 2121 and elastically abuts against the insertion section 2213. In this setting, the flanging structure 2122 is in an open shape. When assembling the second terminal 22, the first insertion part 2212 first elastically abuts against the arc-shaped flanging. The elastic force of the arc-shaped flanging squeezes the first insertion part 2212 toward the middle, causing the plurality of insertion sections 2213 to undergo elastic deformation and approach each other, so as to smoothly insert into the insertion hole 2121 and stably elastically conduct with the edge of the insertion hole 2121. At the same time, the arc-shaped flanging also elastically abuts against the insertion section 2213, increasing the contact points and contact area between the first terminal 21 and the second terminal 22, improving the stability of the insertion between the first terminal 21 and the second terminal 22, and it can be applied to high-current usage environments.

[0040] Please refer to Figure 6 and Figure 7 , Further, in some embodiments, the second elastic piece 222 is provided with a second abutting part 2221 and a plurality of elastic supporting parts 2222. The elastic supporting parts 2222 and the second abutting part 2221 are bent at a certain angle. The elastic supporting parts 2222 are compressed and deformed to provide elastic force to the second abutting part 2221 to ensure the stable contact between the second abutting part 2221 and the panel 300; at the same time, it can ensure the floating connection between the second elastic piece 222 and the panel, avoiding poor conduction caused by inaccurate positioning between the second elastic piece 222 and the panel, and ensuring the stability of the conduction between the second elastic piece 222 and the panel.

[0041] Further, in some embodiments, the second terminal 22 is further provided with a clamping part 223. The clamping part 223 is arranged between the first elastic piece 221 and the second elastic piece 222, and clamping structures 2231 are arranged on one side or both sides in its width direction. Correspondingly, a clamping groove 2322 is provided on the inner wall of the second chamber 232, and the clamping structure 2231 is fixedly connected to the clamping groove 2322. When installing the second terminal 22, the clamping part 223 is inserted into the clamping groove 2322 and inserted toward the first terminal 21 along the clamping groove 2322. The clamping structure 2231 interferes and is fixedly connected to the inner wall of the clamping groove 2322 to fix the second terminal 22 in the second chamber 232, ensuring the stable conduction between the second terminal 22 and the first terminal 21 and the panel 300 respectively.

[0042] Further, in some embodiments, the clamping groove 2322 extends upward along the inner wall of the second chamber 232 to abut against the fixing portion 212, which can further support the fixing portion 212 and further prevent the fixing portion 212 from deforming under force and affecting the electrical connection between the first terminal 21 and the second terminal 22.

[0043] Further, in some embodiments, the second terminal 22 is further provided with a connecting portion 224, which extends and connects to the clamping portion 223 and is disposed on one or both sides of the second elastic piece 222 for connecting the tape. Further, the connecting portion 224 is entirely disposed within the second chamber 232 to avoid interference with the panel, which can ensure that the first elastic piece 221 is inserted in place and maintains a stable electrical connection with the first terminal 21. At the same time, the connecting portion 224 can also limit the movement of the second elastic piece 222 to prevent the second elastic piece 222 from being overly stressed and causing elastic fatigue, thereby affecting its stable contact with the panel, which will not be elaborated here.

[0044] Please refer to Figure 2-4 , further, in some embodiments, the male housing 20 or the female housing 10 is provided with a first seal 13 to achieve a sealed insertion between the male housing 20 and the female housing 10. In this embodiment, the female housing 10 is provided with a plug 11 that is inserted into the first chamber 231 through the first insertion port 2311 and is electrically connected to the first terminal 21. The outer wall of the plug 11 is provided with a first seal groove 12, and a first seal 13 is provided in the first seal groove 12 to be in sealed abutment with the inner wall of the first chamber 231, achieving a sealed connection on one side of the first insertion port 2311. Thus, a sealed insertion between the male housing 20 and the female housing 10 is achieved.

[0045] Further, a second seal groove 2323 is provided at the end of the second chamber 232 close to the panel 300, and a second seal 2324 is provided in the second seal groove 2323. When the male housing 23 is fixed to the panel 300, the second seal 2324 is in sealed abutment with the panel 300 to achieve sealing on one side of the second insertion port 2321, which can ensure the waterproof connection between the male housing 20 and the female housing 10 and the panel 300 respectively, realizing the waterproof installation of the connector.

[0046] Further, in some embodiments, positioning portions 233 are extended from both sides of the outer wall of the second chamber 232, and the positioning portions 233 are fixedly connected to the panel 300. It can be understood that the positioning portions 233 can be fixedly connected to the panel 300 through locking members 2332 or other fixing structures. In this embodiment, positioning holes 2331 are provided in the positioning portions 233, and locking hole positions 301 are correspondingly provided on the panel 300. The locking members 2332 pass through the positioning holes 2331 and are locked to the locking hole positions 301 to realize the fixed connection between the male socket 20 and the panel 300, which can avoid the misalignment between the second terminals 22 and the panel 300 caused by environmental vibration during the use of the connector, thereby affecting the connection stability between the two.

[0047] Please refer to Figure 4 , further, in some embodiments, the female socket 10 and the male socket 20 are snap-connected through a snap structure to prevent the female socket 10 and the male socket 20 from being disengaged under force or vibration, resulting in unstable electrical connection of the connector. As an example, the female socket 10 is provided with elastic arm hooks 14, and the male socket 20 is provided with latching positions 2313. Specifically, the latching positions 2313 are provided on the outer wall of the first chamber 231.
