Description

Technical Field

[0001] This application relates to a liquid accumulation detection connector. Background Technology

[0002] In recent years, with the continuous development of technology, the number and types of electronic devices that accompany our lives have increased dramatically, such as: tablet computers, laptops, desktop computers, smartphones, smartwatches, portable media players, surveillance equipment, audio equipment, drones, smart game consoles, storage devices, in-vehicle entertainment systems, and so on.

[0003] These electronic devices share data and power via cables, which typically require connectors at both ends to insert into mating connectors on the electronic device to transmit signals (including electrical signals). However, in the complexities of everyday use, liquids can sometimes inadvertently enter the connector sockets, such as from user sweat or splashes. Liquids entering the connector sockets can corrode the conductive terminals, especially liquids that seep into the connector through internal manufacturing gaps. Because these liquids have penetrated the interior, they are difficult to wipe or shake off, easily damaging the connector (e.g., causing corrosion or short circuits). Therefore, in real-world applications, there is a desire for methods to detect liquids inside connector sockets, allowing for effective and targeted measures to eliminate them and prevent connector damage.

[0044] Please see Figures 1 to 7 As shown, this application discloses a liquid accumulation detection connector, including a terminal assembly 100 and a metal housing 200 surrounding the terminal assembly 100. The terminal assembly 100 includes an insulating base 1 and several upper terminal pieces 2, several lower terminal pieces 3, and four detection terminals 4 fixed within the insulating base 1. The insulating base 1 has a base section 11 (… Figure 7In the middle, along the front-back direction, the portion behind the dividing line C) and a tongue segment 12 formed by extending forward from the base segment 11. The tongue segment 12 forms a tongue root segment 121 that connects to the front end of the base segment 11 along the front-back direction. Figure 7 The portion between dividing lines B and C along the front-back direction and the tip of the tongue 122 connected to the front end of the root segment 121 along the front-back direction. Figure 7 In the middle, along the front-back direction, the portion in front of the dividing line B). Along the up-down direction, the thickness of the tongue tip segment 122 is less than the rear end of the tongue root segment 121.

[0045] Each of the plurality of upper terminal components 2 includes an upper terminal fixing section (unnumbered) embedded and fixed within the base section 11 and the tongue section 121, an upper terminal contact section (unnumbered) extending forward from the upper terminal fixing section to form an upper terminal contact section, and an upper terminal mating section (unnumbered) extending rearward from the upper terminal fixing section beyond the base section 11 for electrical contact with the mating circuit board 300. The plurality of upper terminal contact sections are arranged in a row along the left-right direction on the upper surface of the tongue section 122, with a portion of the contact section protruding beyond the upper surface of the tongue section 122 for contact with the mating connector.

[0046] Furthermore, each of the plurality of lower terminal components 3 includes a lower terminal fixing section (unnumbered) embedded and fixed within the base section 11 and the tongue section 121, a lower terminal contact section (unnumbered) extending forward from the lower terminal fixing section to form a lower terminal contact section, and a lower terminal mating section (unnumbered) extending rearward from the lower terminal fixing section beyond the base section 11 for electrical contact with the mating circuit board 300. The plurality of lower terminal contact sections are arranged in a row along the left-right direction on the lower surface of the tongue section 122, with a portion exposed outside the lower surface of the tongue section 122 for contact with the mating connector. The plurality of lower terminal mating sections and the plurality of upper terminal mating sections are arranged in a row along the left-right direction at the rear end position of the base section 11.

[0047] The metal housing 200 includes an inner metal housing 201 and an outer metal housing 202 surrounding the inner metal housing 201. In a preferred embodiment, the inner metal housing 201 is formed from a metal plate or metal tube through a drawing and stretching process, resulting in a seamless structure. Specifically, the inner metal housing 201 comprises a cylindrical outer peripheral wall 2011 open at both ends, an annular rear end connecting wall 2012 extending axially from the rear end edge of the outer peripheral wall 2011, and a cylindrical inner peripheral wall 2013 extending forward from the inner peripheral edge of the rear end connecting wall 2012. Preferably, the cylindrical inner peripheral wall 2013 is coaxial with the cylindrical outer peripheral wall 2011.

[0048] Please refer to Figure 7 and combined Figure 3 and Figure 4As shown, the cylindrical inner peripheral wall 2013 is fixed around the outer periphery of the tongue root segment 121 and does not extend forward beyond the front edge of the tongue root segment 121. The outer peripheral surface of the tongue end segment 122, the outer peripheral surface of the cylindrical inner peripheral wall 2013, the front surface of the annular rear end connecting wall 2012, and the inner peripheral surface of the cylindrical outer peripheral wall 2011 together define an annular insertion space 1001 for inserting the mating connector. The insertion space 1001 forms an insertion port at its front end that communicates with the outside.

[0049] Please refer to the reference. Figures 3 to 5 and Figure 7 As shown in the preferred embodiment of this application, the insulating base 1 includes a first insulating element 101 and a second insulating element 102. Specifically, after a plurality of upper terminal components 2, a plurality of lower terminal components 3, and four detection terminals 4 are positioned and fixed by a mold, the first insulating element 101 is formed by a first injection molding. At this time, a through hole 103 is formed at the tongue section 12 of the first insulating element 101. The through hole 103 is mainly formed after the positioning mold used to position the plurality of upper terminal components 2, the plurality of lower terminal components 3, and the four detection terminals 4 during the first injection molding is pulled out. After the first insulating element 101 is formed by the first injection molding, a second injection molding is performed to form the second insulating element 102. The second insulating element 102 is mainly used to fill structures such as the through hole 103, so that the outer surface of the finally formed insulating base 1 is flat.

[0050] Furthermore, after the first insulating component 101 and the second insulating component 102 are injection molded to finally form the insulating seat 1, a joint seam 10 will be formed at the joint position of the first insulating component 101 and the second insulating component 102. Multiple joint seams 10 are formed on the tongue segment 12. More specifically, the joint seam 10 is provided at the joint position of the tongue root segment 121 and the tongue tip segment 122, mainly used to position the middle position of the upper terminal component 2 and the middle position of the lower terminal component 3 during the first injection molding. Furthermore, the joint seam 10 connects the upper surface and the lower surface of the tongue segment 12 in the vertical direction.

[0051] Each of the detection terminals 4 includes a fixed section 41 embedded in the base section 11, a head section 42 extending forward from the fixed section 41 and fixed to the tongue section 12, and a mating section (not shown) extending from the rear end of the base section 11 out of the insulating base 1 for electrical contact with the mating circuit board 300. In a preferred embodiment, a portion of the surface of the head section 42 of the detection terminal 4 is connected to the same joint seam 10. In a preferred embodiment, the head section 42 of the detection terminal 4 is not exposed outside the surface of the tongue section 12. All parts of each detection terminal 4, except for the mating section, are embedded inside the insulating base 1.

[0052] Please refer to Figure 2 and Figure 6 As shown, in a preferred embodiment of this application, a row of upper terminal components 2, from left to right, consists of a grounding terminal, a power terminal, a detection terminal 4, four signal terminals, another detection terminal 4, a power terminal, and a grounding terminal. The row of upper terminal components 2, from left to right, consists of a predetermined terminal (or grounding terminal), a power terminal, a detection terminal 4, four signal terminals, another detection terminal 4, a power terminal, and a grounding terminal. The two detection terminals 4 located at the top and the two detection terminals 4 located at the bottom are arranged in a one-to-one correspondence. In a preferred embodiment, the head segments 42 of the two detection terminals 4 corresponding in the vertical direction communicate with the same joint seam 10. The front portions of the head segments 42 of the two detection terminals 4 communicating with the same joint seam 10 at least partially overlap in the vertical direction.

[0053] Furthermore, in a preferred embodiment, the plurality of lower terminal mating segments, the plurality of upper terminal mating segments, and the four mating segments are arranged in a row along the left-right direction at the rear end position of the base segment 11. The front edge of the head segment 42 of the detection terminal 4 is located behind the front edge of any one of the upper terminal members 2 or the front edge of any one of the lower terminal members 3 (the detection terminal 4 is designed to be shorter).

[0054] In a preferred embodiment, the front edge of the head segment 42 of the detection terminal 4 is located at the junction of the tongue root segment 121 and the tongue tip segment 122. This is because the overall width of the tongue tip segment 122 is relatively small, and the spacing between adjacent terminals (adjacent upper terminal 2 or adjacent lower terminal 3) in the left-right direction is already very small, making it difficult to further extend the head segment 42 of the detection terminal 4. Furthermore, at the junction of the rear end of the tongue tip segment 122 and the front end of the tongue root segment 121 (basically at the midpoint of the front-back direction of the upper terminal 2 or lower terminal 3), this location is often where the through hole 103 is created after the upper terminal 2 and lower terminal 3 are positioned during the first injection molding. Liquid accumulation at this location makes it easier for liquid to penetrate inward through the joint seam 10, potentially corroding the upper terminal 2 or lower terminal 3, and even risking a short circuit between the upper terminal 2 and lower terminal 3. Therefore, in a preferred embodiment, the front edge of the head segment 42 of the detection terminal 4 is located at the junction of the tongue root segment 121 and the tongue tip segment 122, and at least a portion of the surface of the head segment 42 of the detection terminal 4 is connected to the corresponding junction 10. When there is fluid accumulation at the corresponding position of the tongue segment 12, the fluid will seep inward along the junction 10 and be detected by the detection terminal 4 connected to the junction 10.

[0055] In a preferred embodiment of this application, the through hole 103 is located between two adjacent upper terminal members 2 and between two adjacent lower terminal members 3. At least one side of an upper terminal member 2 and / or at least one side of a lower terminal member 3 communicates with the joint seam 10. Further, in one embodiment, the inner wall surface of the through hole 103 includes at least an inner wall surface portion 1031 of a first insulating member 101 extending along a vertical plane, a side surface portion 4032 of a head segment 42 extending along a vertical plane, a side surface portion 2033 of one of the upper terminal members 2 extending along a vertical plane, and a side surface portion (not shown) of one of the lower terminal members 3 extending along a vertical plane.

[0056] In this application, the insulating seat 1 is formed by two injection molding processes, and of course, it can also be formed by three injection molding processes. Of course, in the case of three injection molding processes, the joint seam 10 can be formed between any two insulators. Of course, in the preferred embodiment, the joint seam 10 is also in the form of connecting the upper surface and the lower surface of the tongue segment 12 in the vertical direction.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.

[0058] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
