Description

Technical Field

[0001] This utility model relates to the field of USB connectors, specifically a USB Type-C male connector plug. Background Technology

[0002] like Figure 1 As shown, the USB Type-C interface definition specified by the USB Association defines the USB Type-C male connector as follows:

[0003] The USB Type-C male connector includes two sets of terminals, Group A and Group B, arranged vertically. Group A has terminals A1-A12 arranged side-by-side, and Group B has terminals B1-B12 arranged side-by-side, with terminals A1-A12 and B12-B1 symmetrically distributed. Terminals {A1, B12} and {A12, B1} are symmetrically distributed and defined as the electrical connection for power supply GND; terminals {A4, B9} and {A9, B4} are symmetrically distributed and defined as the electrical connection for power supply VBUS.

[0004] In the existing technology, the two sets of terminals, A and B, are set independently. To avoid accidental contact between the pins of the two sets of terminals and causing a short circuit, the two sets of terminals need to be inserted into the core module for fixation. On the other hand, the electrical connection between the two sets of terminals, A and B, needs to be achieved through a separately configured circuit board.

[0005] Obviously, the aforementioned existing technology requires the use of circuit boards to achieve electrical connections between terminals, which makes the production process of USB Type-C male plugs complicated and the product cost high. Utility Model Content

[0006] The present invention aims to overcome the shortcomings of the prior art and provide a USB Type-C male connector that does not require the installation of a circuit board, thereby effectively simplifying the processing steps and reducing product costs.

[0007] To achieve the above objectives, the present invention adopts the following technical solution.

[0008] A USB Type-C male connector includes a metal housing that extends from front to back, a rubber core inside the metal housing, and a terminal assembly inserted into the rubber core;

[0009] The core includes an upper module and a lower module that interlock.

[0010] The terminal assembly includes a first upper terminal, a second upper terminal, a third upper terminal, a fourth upper terminal, a fifth upper terminal, a sixth upper terminal, and a seventh upper terminal that are plugged into the upper module, and a first lower terminal, a second lower terminal, a third lower terminal, and a fourth lower terminal that are plugged into the lower module. The second lower terminal and the third lower terminal are single-pin dual-pin structures that are integrated at the rear. The first upper terminal, the second upper terminal, the third upper terminal, the fourth upper terminal, the fifth upper terminal, the sixth upper terminal, the seventh upper terminal, the first lower terminal, the second lower terminal, the third lower terminal, and the fourth lower terminal correspond to the A12, A9, A7, A6, A5, A4, A1, B1, B4, B9, and B12 pins in the Type-C interface definition specified by the USB Association, respectively.

[0011] The bottom surface of the upper module has a first window that exposes a portion of the first upper terminal, a second window that exposes a portion of the seventh upper terminal, a third window that exposes a portion of the second upper terminal, and a fourth window that exposes a portion of the sixth upper terminal;

[0012] The top surface of the lower module has a fifth window that exposes a portion of the first lower terminal, a sixth window that exposes a portion of the fourth lower terminal, a seventh window that exposes a portion of the second lower terminal, and an eighth window that exposes a portion of the third lower terminal.

[0013] One of the first upper terminal and the first lower terminal forms a first conductive pin that passes through the first window and the fifth window. The first conductive pin is connected between the first upper terminal and the first lower terminal to form a conductive path.

[0014] One of the seventh upper terminal and the fourth lower terminal forms a second conductive pin that passes through the second window and the sixth window. The second conductive pin is connected between the seventh upper terminal and the fourth lower terminal to form a conductive path.

[0015] One of the second upper terminal and the second lower terminal forms a third conductive pin that passes through the third window and the seventh window. The third conductive pin is connected between the second upper terminal and the second lower terminal to form a conductive path.

[0016] One of the sixth upper terminal and the third lower terminal forms a fourth conductive pin that passes through the fourth window and the eighth window. The fourth conductive pin is connected between the sixth upper terminal and the third lower terminal to form a conductive path.

[0017] Compared with the prior art, the present invention has the following advantages: the terminals in the core are connected by a conductive pin structure, which can realize the electrical connection of the terminals that conform to the USB Association's Type-C interface definition without the need to install a circuit board. This reduces the need for circuit board installation, effectively simplifies the assembly process, and significantly reduces product costs.

[0018] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

Detailed Implementation

[0034] like Figures 2 to 11 As shown, in one embodiment, a USB Type-C male connector of the present invention includes a metal shell 1 that extends through the front and back, a rubber core 2 provided in the metal shell 1, and a terminal assembly 3 inserted into the rubber core 2.

[0035] The core 2 includes an upper mold 21 and a lower mold 22 that are interlocked.

[0036] Terminal assembly 3 includes a first upper terminal 301, a second upper terminal 302, a third upper terminal 303, a fourth upper terminal 304, a fifth upper terminal 305, a sixth upper terminal 306, and a seventh upper terminal 307 inserted into the upper module 21, and a first lower terminal 308, a second lower terminal 309, a third lower terminal 310, and a fourth lower terminal 311 inserted into the lower module 22. The second lower terminal 309 and the third lower terminal 310 are a single-pin dual-needle structure that is integrated at the rear. The first upper terminal 301, the second upper terminal 302, the third upper terminal 303, the fourth upper terminal 304, the fifth upper terminal 305, the sixth upper terminal 306, the seventh upper terminal 307, the first lower terminal 308, the second lower terminal 309, the third lower terminal 310, and the fourth lower terminal 311 correspond to the A12, A9, A7, A6, A5, A4, A1, B1, B4, B9, and B12 pins in the Type-C interface definition specified by the USB Association, respectively.

[0037] The bottom surface of the upper module 21 is provided with a first window 211 that exposes a portion of the first upper terminal 301, a second window 212 that exposes a portion of the seventh upper terminal 307, a third window 213 that exposes a portion of the second upper terminal 302, and a fourth window 214 that exposes a portion of the sixth upper terminal 306;

[0038] The top surface of the lower module 22 is provided with a fifth window 221 that exposes a portion of the first lower terminal 308, a sixth window 222 that exposes a portion of the fourth lower terminal 311, a seventh window 223 that exposes a portion of the second lower terminal 309, and an eighth window 224 that exposes a portion of the third lower terminal 310.

[0039] One of the first upper terminal 301 and the first lower terminal 308 forms a first conductive pin 91 that passes through the first window 211 and the fifth window 221. The first conductive pin 91 is connected between the first upper terminal 301 and the first lower terminal 308 to form a conductive path.

[0040] One of the seventh upper terminal 307 and the fourth lower terminal 311 forms a second conductive pin 92 that passes through the second window 212 and the sixth window 222. The second conductive pin 92 is connected between the seventh upper terminal 307 and the fourth lower terminal 311 to form a conductive path.

[0041] One of the second upper terminal 302 and the second lower terminal 309 forms a third conductive pin 93 that passes through the third window 213 and the seventh window 223. The third conductive pin 93 is connected between the second upper terminal 302 and the second lower terminal 309 to form a conductive path.

[0042] One of the sixth upper terminal 306 and the third lower terminal 310 forms a fourth conductive pin 94 that passes through the fourth window 214 and the eighth window 224. The fourth conductive pin 94 is connected between the sixth upper terminal 306 and the third lower terminal 310 to form a conductive path.

[0043] like Figure 10 As shown, in the above embodiment, the first upper terminal 301, the second upper terminal 302, the third upper terminal 303, the fourth upper terminal 304, the fifth upper terminal 305, the sixth upper terminal 306, the seventh upper terminal 307, the first lower terminal 308, the second lower terminal 309, the third lower terminal 310, and the fourth lower terminal 311 correspond to the A12, A9, A7, A6, A5, A4, A1, B1, B4, B9, and B12 pins in the Type-C interface definition specified by the USB Association, respectively. Therefore, the USB Type-C male plug provided by this utility model conforms to the architecture of the Type-C interface definition specified by the USB Association and can also support reversible insertion.

[0044] like Figure 11As shown, in an exemplary embodiment, a first conductive pin 91 is selectively formed with a first lower terminal 308, a second conductive pin 92 is formed with a fourth lower terminal 311, a third conductive pin 93 is formed with a second lower terminal 309, and a fourth conductive pin 94 is formed with a third lower terminal 310.

[0045] Combination Figure 9 , Figure 10 and Figure 11 As shown, in the above embodiment, the second lower terminal 309 and the third lower terminal 310 are a single-pin dual-pin structure that is integrated at the rear end. Moreover, the B5, B6, B7, and B8 pins corresponding to the Type-C interface definition specified by the USB Association are removed between the second lower terminal 309 and the third lower terminal. Therefore, the second lower terminal 309 and the third lower terminal 310 can be widened at the junction, which provides better support for high current.

[0046] Combination Figure 10 and Figure 11 As shown, in the above embodiment, the first upper terminal 301 and the first lower terminal 308 are connected and conductive through the first conductive pin 91; the seventh upper terminal 307 and the fourth lower terminal 311 are connected and conductive through the second conductive pin 92; the second upper terminal 302 and the second lower terminal 309 are connected and conductive through the third conductive pin 93; and the sixth upper terminal 306 and the third lower terminal 310 are connected and conductive through the fourth conductive pin 94. Corresponding to the Type-C interface definition specified by the USB Association, the circuit connections of pins A12 and B1, pins A9, A4, B4, and B9, and pins A1 and B12 have been achieved. Obviously, the above embodiment can achieve the electrical connection of the terminals in the Type-C interface definition specified by the USB Association without installing a circuit board, and the cable can be directly connected to the rear end of each terminal.

[0047] Therefore, compared with the prior art, the present invention reduces the embedding and installation of circuit boards, effectively simplifies the assembly process, and significantly reduces product costs.

[0048] In the above embodiments, the first conductive pin 91 can be elastically fitted between the first upper terminal 301 and the first lower terminal 308, or it can be rigidly fitted between the first upper terminal 301 and the first lower terminal 308. Similarly, the second conductive pin 92, the third conductive pin 93, and the fourth conductive pin 94 can also be elastically fitted or rigidly fitted to the terminals they are fitted with.

[0049] In another preferred embodiment, combined with Figure 4 , Figure 10 and Figure 11As shown, the first upper terminal 301 and the seventh upper terminal 307 are both formed with a first grounding contact 81 extending through the upper module 21, and the first lower terminal 308 and the fourth lower terminal 311 are both formed with a second grounding contact 82 extending through the lower module 22. The first grounding contact 81 and the second grounding contact 82 respectively contact the inner wall of the metal shell 1. Through the aforementioned arrangement, the first upper terminal 301, the seventh upper terminal 307, the first lower terminal 308, and the fourth lower terminal 311 are all in contact with the metal shell 1. This not only enables the metal shell 1 of the USB Type-C male plug to be grounded, thus shielding against external interference, but also allows the first upper terminal 301, the seventh upper terminal 307, the first lower terminal 308, and the fourth lower terminal 311 to form a parallel closed-loop circuit, providing better support for high current.

[0050] Furthermore, to facilitate cable connection, such as Figure 4 As shown, the rear ends of the upper module 21 and the lower module 22 extend out of the metal housing 1 to form cable connection portions 23. The rear ends of one of the second upper terminal 302, the sixth upper terminal 306, the second lower terminal 309, and the third lower terminal 310 form a first pad 231 exposing the cable connection portion 23; the rear end of the third upper terminal 303 forms a second pad 232 exposing the cable connection portion 23; the rear end of the fourth upper terminal 304 forms a third pad 233 exposing the cable connection portion 23; the rear end of the fifth upper terminal 305 forms a fourth pad 234 exposing the cable connection portion 23; and the rear ends of one of the first upper terminal 301, the first lower terminal 308, the seventh upper terminal 307, and the fourth lower terminal 311 form a fifth pad 235 exposing the cable connection portion 23. The cable cores are soldered to the first pad 231, the second pad 232, the third pad 233, the fourth pad 234, and the fifth pad 235 respectively, facilitating connection.

[0051] In the above implementation, pins B2, B3, B5, B6, B7, B8, B10, B11, A11, A10, A5, A3, and A2 corresponding to the Type-C interface definition specified by the USB Association have been removed. Therefore, the first pad 231, the second pad 232, the third pad 233, the fourth pad 234, and the fifth pad 235 all have room for widening design, which provides better support for high current.

[0052] Furthermore, such as Figure 4As shown, the first pad 231, the second pad 232, the third pad 233, the fourth pad 234, and the fifth pad 235 are located on the same side of the cable connector 23. Therefore, when the cable core wires are soldered to the first pad 231, the second pad 232, the third pad 233, the fourth pad 234, and the fifth pad 235 respectively, the soldering operation can be performed on the same side of the cable connector 23. Especially when using automated equipment for soldering, this reduces the complexity of the equipment structure and, to some extent, speeds up the soldering process, thus helping to improve assembly efficiency.

[0053] like Figure 7 and Figure 11 As shown, in an exemplary embodiment, the rear end of the second upper terminal 302 forms a first pad 231 exposing the cable connection portion 23, the rear end of the third upper terminal 303 forms a second pad 232 exposing the cable connection portion 23, the rear end of the fourth upper terminal 304 forms a third pad 233 exposing the cable connection portion 23, the rear end of the fifth upper terminal 305 forms a fourth pad 234 exposing the cable connection portion 23, and the rear end of the seventh upper terminal 307 forms a fifth pad 235 exposing the cable connection portion 23.

[0054] In another preferred embodiment, refer to Figure 6 and Figure 8 The bottom surface of the upper module 21 forms a positioning protrusion 24, and the top surface of the lower module 22 forms a positioning groove 25 that matches the positioning protrusion 24. When the upper module 21 and the lower module 22 are engaged, the positioning protrusion 24 fits into the positioning groove 25, so that the upper module 21 and the lower module 22 remain fixed in the horizontal direction, reducing the assembly difficulty.

[0055] Preferably, multiple positioning protrusions 24 and positioning grooves 25 are provided, and the positioning protrusions 24 and positioning grooves 25 correspond one-to-one.

[0056] In another preferred embodiment, refer to Figure 3 and Figure 4 The core 2 also includes a sleeve 26 fitted onto the front end of the upper module 21 and the lower module 22. The inner wall of the sleeve 26 forms an upper terminal groove 261 on its upper side for the front sections of the first upper terminal 301, second upper terminal 302, third upper terminal 303, fourth upper terminal 304, fifth upper terminal 305, sixth upper terminal 306, and seventh upper terminal 307 to be inserted. The inner wall of the sleeve 26 also forms a lower terminal groove 262 on its lower side for the front sections of the first lower terminal 308, second lower terminal 309, third lower terminal 310, and fourth lower terminal 311 to be inserted. The sleeve 26 serves as a connector for the USB Type-C male plug to mate with the female socket. It also limits the installation of the terminal assembly 3 through the upper terminal groove 261 and lower terminal groove 262, preventing misalignment and short circuits between the terminals.

[0057] In another preferred embodiment, such as Figure 2 , Figure 3 and Figure 12 As shown, it also includes a latch 7, which has a crossbeam 71 clamped and engaged between the upper module 21 and the lower module 22, and a pair of side arms 72 respectively disposed at the left and right ends of the crossbeam 71. The side arms 72 extend forward and engage with the left and right sides of the rubber sleeve 26. The left and right sides of the rubber sleeve 26 respectively form notches 260 corresponding to the side arms 72, and the inner edge of the side arms 72 enters the interior of the rubber sleeve 26 through the notches 260. The latch 7 is used to engage with a USB Type-C female socket, which is a conventional setting in this field. Therefore, the working principle of the latch 7 will not be described in detail.

[0058] Better, combination Figure 6 and Figure 8 As shown, the bottom surface of the upper module 21 forms a first positioning groove 27 that mates with the crossbeam 71, and the top surface of the lower module 22 forms a second positioning groove 28 that mates with the crossbeam 71. The first positioning groove 27 and the second positioning groove 28 cooperate with each other to form a cavity that just accommodates the crossbeam 71, so that the hook 7 is limited in the horizontal direction relative to the core 2.

[0059] Better, such as Figure 12 As shown, the two ends of the crossbeam 71 respectively form the third grounding contact 83 of the wide rubber core 2. The third grounding contact 83 respectively contacts the inner wall of the metal shell 1, the purpose of which is to realize the grounding connection of the hook 7.

[0060] Better, such as Figure 6 , Figure 8 and Figure 9 As shown, the first window 211 and the second window 212 are exactly located in the first positioning slot 27, and the fifth window 221 and the sixth window 222 are exactly located in the second positioning slot 28. In combination... Figure 13 As shown, in order to prevent the crossbeam 71 of the hook 7 from blocking the first conductive foot 91 and the second conductive foot 92, a clearance opening 70 is provided on the crossbeam 71 to allow the first conductive foot 91 and the second conductive foot 92 to pass through.

[0061] In various embodiments of this utility model, preferably, the first upper terminal 301, the second upper terminal 302, the third upper terminal 303, the fourth upper terminal 304, the fifth upper terminal 305, the sixth upper terminal 306, and the seventh upper terminal 307 are injection molded into the upper module 21 using in-mold inserts, and the first lower terminal 308, the second lower terminal 309, the third lower terminal 310, and the fourth lower terminal 311 are injection molded into the lower module 22 using in-mold inserts.

[0062] To provide a more intuitive understanding of the technical solution and effects of this utility model, the electrical definitions of each terminal of the terminal assembly 3 in this utility model will be further explained below.

[0077] Given the above configuration, the USB Type-C male connector of this utility model reduces the need for circuit board mounting, can still be blindly inserted in both directions, and can support high current.
