Description

Technical Field

[0001] This application relates to the field of electronic technology, specifically to a connector and an electronic device. Background Technology

[0002] In daily life, many products have connectors. A connector is a device that bridges two conductors in a circuit, allowing current or signals to flow from one conductor to the other. For example, a charger has a male connector, and a data cable has a female connector. When the charger and data cable connectors are mated, charging or data transmission functions can be achieved.

[0003] In related technologies, female connectors on data cables typically have grounding, power, and signal terminals. They are generally manufactured using a single injection molding process, where each terminal is mounted onto a molded plastic sheet. A metal shell is then used to encase the plastic sheet containing the terminals. However, due to the limitations of the injection mold, after the single injection molding process, ejector pin holes and ejector holes are left in the plastic sheet, causing parts of the terminals to protrude from these holes. External liquids can easily flow into these holes through the gaps between the metal shell and the plastic, potentially causing a short circuit between the metal shell and the terminals, resulting in a large current. This can lead to abnormally high connector temperatures and even burn-out. Utility Model Content

[0004] In view of this, this application provides a connector, data cable, and electronic device that can prevent connector burn-out and improve the safety of connector use.

[0005] On one hand, embodiments of this application provide a connector, which includes a housing, a base, and a terminal assembly;

[0006] The housing has a cavity, and the cavity has an insertion interface in the insertion / removal direction;

[0007] The seat is located within the insertion cavity and extends along the insertion / removal direction;

[0008] The terminal assembly is mounted on the base body. The terminal assembly includes a plurality of first terminals arranged side by side. Each first terminal includes a plug-in surface and a fixing surface facing away from each other. The fixing surface is covered by the base body, and the portion of the plug-in surface near the plug-in interface is exposed from the base body.

[0009] Optionally, the cavity includes opposing first and second cavity walls;

[0010] The seat includes a first surface and a second surface facing away from each other, the first surface abutting against the first cavity wall, and the second surface facing the second cavity wall;

[0012] Optionally, the base includes a first support member and a second support member;

[0013] The first support member and the first terminal are injection molded as one piece. A portion of the fixing surface is exposed from the first support member. The first support member has a plurality of first through holes. The axial direction of the first through holes is perpendicular to the second cavity wall. The first through holes penetrate the first support member.

[0014] The second support member is injection molded integrally with the first support member. The second support member blocks one end of the first through hole facing the first cavity wall and covers the portion of the fixing surface exposed on the first support member.

[0015] Optionally, the first support member includes a plurality of first slots arranged side by side, the openings of the first slots facing the second cavity wall, and the first slots corresponding one to one with the first terminals;

[0016] The first terminal is inserted into the corresponding first slot.

[0017] Optionally, the cavity further includes opposing third and fourth cavity walls, wherein the first cavity wall, the third cavity wall, the second cavity wall, and the fourth cavity wall are connected in sequence;

[0018] The seat includes a first side and a second side facing away from each other. The first surface, the first side, the second surface and the second side are connected in sequence. The first side and the second side abut against the third cavity wall and the fourth cavity wall, respectively.

[0019] Optionally, a portion of the second side is recessed away from the fourth cavity wall and forms a liquid storage tank with the fourth cavity wall and the first cavity wall.

[0020] Optionally, in the insertion / removal direction, the two ends of the liquid reservoir are located on the outer side of the end of the insertion surface that is close to the insertion interface and exposed from the seat body.

[0021] Optionally, the plurality of first terminals are respectively a power terminal, a first signal terminal, a second signal terminal and a ground terminal, the first signal terminal and the second signal terminal are located between the power terminal and the ground terminal, and the liquid storage tank is adjacent to the power terminal.

[0022] On the other hand, this application embodiment also provides a data line, which includes the connector described in any one of the above embodiments of this application.

[0023] On the other hand, this application also provides an electronic device, which includes the data cable described in the above-described embodiments of this application.

[0024] The connector provided in this application embodiment includes a housing, a base, and multiple terminal assemblies. The housing has a cavity with an insertion interface in the insertion / removal direction. The connector on the mating side can be inserted into the cavity in the insertion / removal direction to mate with the connector. The base is located within the cavity and extends in the insertion / removal direction. The terminal assembly is mounted on the base and includes multiple first terminals arranged side by side. Each first terminal includes a mating surface and a fixing surface facing away from each other. A portion of the mating surface protrudes from the base, allowing communication with the corresponding terminal of the mating connector. Because the fixing surface is covered by the base, liquid flowing between the base and the cavity is blocked by the base and cannot contact the fixing surface of the first terminal. Therefore, a short circuit caused by liquid communication between the housing and the fixing surface of the first terminal will not occur, and the connector temperature will not rise abnormally or even burn out due to a short circuit. In other words, the technical solution of this application embodiment can avoid connector burnout and improve the safety of connector use. Attached Figure Description

Detailed Implementation

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by those skilled in the art.

[0038] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0039] Combination Figure 1 and Figure 2 As shown, this application embodiment provides a connector, which includes a housing 100, a base 200, and a terminal assembly 300. It should be noted that the housing 100 and the terminal assembly 300 are made of metal. The base 200 is made of plastic.

[0040] The housing 100 has a cavity 110, which has a mating interface 111 in the insertion / removal direction. The base 200 is located within the cavity 110 and extends in the insertion / removal direction. It should be understood that the mating-side connector can be inserted into the cavity 110 from the mating interface 111 in the insertion / removal direction to mate with the connector.

[0041] Terminal assembly 300 is mounted on base 200. Terminal assembly 300 includes a plurality of first terminals 310 arranged side by side. Each first terminal 310 includes a mating surface 311 and a fixing surface 312 facing away from each other. The fixing surface 312 is covered by base 200. The portion of the mating surface 311 near the mating interface 111 protrudes from base 200. It should be understood that the portion of the mating surface 311 near the mating interface 111 protruding from base 200 is for contacting the corresponding terminal in the mating connector to achieve electrical connection. It should be noted that the portion of the mating surface 311 away from the mating interface 111 can also protrude from base 200 for soldering to a circuit board.

[0042] It should be noted that, since the fixing surface 312 of the first terminal 310 is covered by the base 200, the liquid flowing between the base 200 and the cavity 110 is blocked by the base 200 and cannot contact the fixing surface 312 of the first terminal 310. Therefore, there will be no short circuit caused by liquid communication between the housing 100 and the fixing surface 312 of the first terminal 310, and there will be no abnormal temperature rise or even burnout of the connector due to short circuit. In other words, the connector provided in this embodiment can avoid burnout and improve the safety of connector use.

[0043] The following is in conjunction with the appendix Figures 1 to 5 The details and functions of the connectors provided in the embodiments of this application will be described in more specific and detailed manner.

[0044] Combination Figure 2 and Figure 3 As shown in some embodiments, the cavity 110 includes opposing first cavity walls 112 and second cavity walls 113. The seat 200 includes opposing first surfaces 210 and second surfaces 220, with the first surface 210 abutting against the first cavity wall 112 and the second surface 220 facing the second cavity wall 113. The portion of the insertion surface 311 near the insertion interface 111 protrudes from the second surface 220, and the fixing surface 312 is located between the first surface 210 and the second surface 220. It should be noted that the seat 200 is made of plastic and has insulating properties. The seat 200 and the first terminal 310 are integrally formed by injection molding. The fixing surface 312 being located between the first surface 210 and the second surface 220 means that the seat 200 can cover the fixing surface 312 of the first terminal 310 during the injection molding process, so that the fixing surface 312 of the first terminal 310 and the first cavity wall 112 are separated by the plastic seat 200. With this configuration, liquid flowing in from the gap between the first cavity wall 112 and the first surface 210 will not come into contact with the fixed surface 312, thereby preventing a short circuit between the first cavity wall 112 and the fixed surface 312 and ensuring the safety of the connector.

[0045] like Figure 4As shown, in some embodiments, the base 200 includes a first support member 230 and a second support member 240. The first support member 230 is injection molded integrally with the first terminal 310, and a portion of the fixing surface 312 protrudes from the first support member 230. It should be noted that the first support member 230 provides initial support and positioning for the first terminal 310. The first support member 230 has multiple first through holes 231, the axial direction of which is perpendicular to the second cavity wall 113, and the first through holes 231 penetrate the first support member 230. It should be noted that the first through holes 231 may be, for example, ejector pin holes and / or material removal holes left after injection molding.

[0046] The second support member 240 is injection molded integrally with the first support member 230. The second support member 240 blocks the end of the first through hole 231 facing the first cavity wall 112 and covers the portion of the fixing surface 312 exposed by the first support member 230. Thus, after the second support member 240 and the first support member 230 are combined, the fixing surface 312 is isolated from the first cavity wall 112 of the housing 100. This prevents liquid between the first cavity wall 112 and the first surface 210 from contacting the fixing surface 312, ensuring that the fixing surface 312 and the first cavity wall 112 will not come into contact and short-circuit, improving the safety of the connector. It should be noted that the upper surface of the second support member 240 may have protrusions 241 corresponding to the first through holes 231. The protrusions 241 are inserted into the corresponding first through holes 231 to block the end of the first through hole 231 facing the first cavity wall 112. Alternatively, a portion of the upper surface of the second support member 240 may abut against one end of the first through hole 231 facing the first cavity wall 112, thereby blocking one end of the first through hole 231 facing the first cavity wall 112.

[0047] like Figure 4 As shown, in some embodiments, the first support member 230 includes a plurality of first slots 232 arranged side by side, the openings of the first slots 232 facing the second cavity wall 113, and each first slot 232 corresponds to a first terminal 310. The first terminal 310 is engaged in the corresponding first slot 232. It should be noted that the first slots 232 can position the first terminal 310 to prevent the first terminal 310 from shifting during the injection molding process of the second support member 240.

[0048] like Figure 3As shown, in some embodiments, the insertion cavity 110 further includes opposing third cavity walls 114 and fourth cavity walls 115, with the first cavity wall 112, third cavity wall 114, second cavity wall 113, and fourth cavity wall 115 sequentially connected. The seat body 200 includes opposing first side surface 250 and second side surface 260, with the first surface 210, first side surface 250, second surface 220, and second side surface 260 sequentially connected, and the first side surface 250 and second side surface 260 abutting against the third cavity wall 114 and the fourth cavity wall 115, respectively. It should be noted that the abutting between the first side surface 250 and the third cavity wall 114, and the abutting between the second side surface 260 and the fourth cavity wall 115, can improve the sealing performance between the first side surface 250 and the third cavity wall 114, and between the second side surface 260 and the fourth cavity wall 115, thereby preventing liquid from flowing in from between the first side surface 250 and the third cavity wall 114, or from between the second side surface 260 and the fourth cavity wall 115.

[0049] like Figure 5 As shown, in some embodiments, a portion of the second side surface 260 is recessed away from the fourth cavity wall 115, forming a liquid storage tank 270 with the fourth cavity wall 115 and the first cavity wall 112. It should be noted that if liquid is present on the second surface 220, it can easily connect the first terminal 310 to the cavity wall of the housing 100, thereby causing a short circuit. Because this embodiment includes a liquid storage tank 270, when liquid flows in from between the first side surface 250 and the third cavity wall 114, or from between the second side surface 260 and the fourth cavity wall 115, or from between the first surface 210 and the first cavity wall 112, it can accumulate in the liquid storage tank 270 and not adhere to the second surface 220, thus reducing the risk of a short circuit. Simultaneously, since only a portion of the second side surface 260 is recessed, the base 200 still maintains high strength.

[0050] like Figure 5 As shown, in some embodiments, in the insertion / removal direction, the two ends of the liquid reservoir 270 are respectively located outside the ends of the insertion surface 311 that are close to the insertion interface 111 and exposed from the base 200. This arrangement not only increases the liquid storage capacity of the liquid reservoir 270, but also increases the creepage distance, reduces the risk of short circuits, and improves the safety of the connector. It should be understood that the creepage distance refers to the path length required for liquid to climb from the bottom of the liquid reservoir 270, i.e., the portion of the first cavity wall 112 forming the liquid reservoir 270, to the second surface 220.

[0051] like Figure 5As shown, in some embodiments, the plurality of first terminals 310 are respectively a power terminal, a first signal terminal, a second signal terminal, and a ground terminal. The first signal terminal and the second signal terminal are located between the power terminal and the ground terminal, and the liquid reservoir 270 is adjacent to the power terminal. It should be noted that the first signal terminal and the second signal terminal can be, for example, differential signal terminals, such as one being a D+ terminal and the other a D- terminal. The power terminal is used to realize the current-carrying function, that is, the current flowing through the power terminal is greater than the current flowing through the first signal terminal, the second signal terminal, and the ground terminal. By placing the liquid reservoir 270 next to the power terminal in this embodiment, the risk of short circuit caused by liquid connecting the housing 100 and the first terminal 310, thereby generating a large current, can be minimized. In other words, the phenomenon of connector burn-out can be avoided to the greatest extent, improving the safety of connector use.

[0052] like Figure 4 As shown, in some embodiments, the base 200 further includes a second through hole 280, and the terminal assembly 300 further includes a second terminal 320 located within the second through hole 280. The second terminal 320 is elastic and can move vertically within the second through hole 280. The second through hole 280 provides sufficient space for the second terminal 320 to ensure that the second terminal 320 can perform its corresponding functions. It should be noted that the second terminal 320 can be, for example, a CC (Configuration Channel) terminal.

[0053] On the other hand, this application embodiment also provides a data cable, which includes the connector described in any one of the above embodiments of this application. It should be noted that the connector in the data cable provided in this application embodiment has the same composition and function as any of the data cables provided in the above embodiments of this application, therefore, it will not be described again here.

It should be noted that the data cable in the electronic device provided in this application has the same composition and function as the data cable provided in the above embodiments of this application, therefore, it will not be described again here.
