Description

Technical Field

[0001] This utility model relates to an electrical connector, specifically an 8-pin raised Type-C connector. Background Technology

[0002] Electrical connectors are widely used in various electronic products. With the rapid development of the electronics industry, there are higher requirements for electrical connectors. The existing electrical connectors have a fixed distance between the insertion port and the terminal plane of the circuit board, which cannot meet the needs of ports of different heights.

[0003] To address this issue, the industry has made improvements to connectors. For example, after increasing the terminal height, a heightening component is usually fitted onto the connector shielding shell to support and stabilize the entire connector. This heightening component has sufficiently tall support feet to support and stabilize the heightened connector, thus accommodating ports of greater height. However, adding the heightening component requires the production of an additional component, increasing assembly requirements, complicating the production process, and significantly increasing production costs, which is detrimental to improving market competitiveness.

[0004] Therefore, technical personnel in the industry continued to improve it, such as Figure 1 As shown, the housing has a first welding foot 1' and a second welding foot 2' flush with it. The two welding feet together support the entire connector. The second welding foot 2' is formed by folding outward from the bottom and is arranged tangentially to the side wall. Thus, the length of the second welding foot 2' is limited by the width of the bottom of the housing. The first welding foot 1' is bent from the top of the housing to the bottom. In order to ensure that it is flush with the second welding foot 2', the bending position of the first welding foot 1' is also on the tangential plane of the side wall. Since the two welding feet need to support the entire connector together, the length of the first welding foot 1' is limited by the influence of the second welding foot 2'.

[0005] like Figure 2 As shown, another type of raised connector in the industry also has solder feet 3' that are bent from the top of the housing to the bottom. The solder feet 3' on both sides of the housing are first bent diagonally downwards and then bent vertically, so that the vertical part of the solder feet 3' is located outside the outer side of the housing. The inclined part of the solder feet 3' reduces the maximum length that the solder feet 3' can reach as a whole. This setting of the solder feet 3' limits the length of the solder feet.

[0006] The length of both types of soldering leads is limited, which cannot meet the needs of connector products that require higher mounting height. The only solution is to use the traditional method of adding a housing, which is obviously not in line with current requirements.

[0007] To address the aforementioned problems, this utility model presents an innovative design for the connector. Utility Model Content

[0008] The purpose of this utility model is to provide an 8PIN raised Type-C connector, which has solder feet symmetrically arranged on both sides of the connector housing. It is formed by borrowing material from the housing and extending it downwards, and the bending position of the solder feet is located on the lower end face of the housing. At the same time, the solder feet on the housing and the fixing posts on the raised base jointly support and stabilize the entire connector, so as to solve the problem that the solder feet cannot meet the height requirements of higher raised connectors.

[0009] To achieve the above objectives, this utility model provides the following technical solution: an 8-pin raised Type-C connector, comprising a housing, an insulating body, and a terminal group. The insulating body includes a raised base and a tongue plate. The terminal group includes two ground terminals, two power terminals, two detection terminals, and two signal terminals. A pair of vertically downward extending solder feet are symmetrically arranged on both sides of the housing. The solder feet are formed by bending material from the upper end face of both sides of the housing along the outer side face to the lower end face, so that the two sides of the housing form symmetrical hollow parts. The bottom of the raised base is provided with a fixing post for fixing on the circuit board. The fixing post and the solder feet are positioned together. The solder feet have a bending position, which is located on the inner side of the outer side face and on the bottom side of the lower end face.

[0010] Preferably, the welding foot is provided with a reinforcing rib, which extends from the lower end face and passes through a bend to the vertical part of the welding foot.

[0011] Preferably, the width of the individual welding foot is smaller than the width of the cutout portion.

[0012] Preferably, the upper inner wall surface of the housing is provided with a first limiting protrusion, and the upper edge of the front end of the raised base is provided with a first limiting groove. The first limiting protrusion is located in the first limiting groove and is fixed in cooperation with the first limiting groove. The upper edge of the rear end of the housing is provided with two limiting parts, and the upper surface of the rear end of the raised base is recessed with two third limiting grooves. The two limiting parts are located in the two third limiting grooves and are fixed in cooperation with the third limiting grooves.

[0013] Preferably, the lower inner wall surface of the housing is provided with a second limiting protrusion, and the lower edge of the front end of the raised base is provided with a second limiting groove. The second limiting protrusion is located in the second limiting groove and is fixed in cooperation with the second limiting groove.

[0014] Preferably, the housing covers the upper part of the raised base and has snap-fit ​​portions extending downward on both sides. The raised base has stepped portions on both sides of the top, and the two snap-fit ​​portions are tightly snapped and fixed in the stepped portions.

[0015] Preferably, the distance between the two welding feet is less than the distance between the two snap-fit ​​parts.

[0016] Preferably, the terminal group includes an upper terminal group and a lower terminal group. The terminals of the upper terminal group are arranged in the following order: a ground terminal, a power terminal, and a detection terminal. The terminals of the lower terminal group are arranged in the following order: a ground terminal, a power terminal, a first signal terminal, a second signal terminal, and a detection terminal.

[0017] Preferably, each terminal of the terminal group includes an integrally formed terminal body, a contact end, and a pin end, the pin end extending from the bottom of the raised base.

[0018] Preferably, the thickness of the terminal group is 2.0 mm.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] By symmetrically arranging a pair of vertically extending solder feet on both sides of the housing of the 8PIN raised Type-C connector, with the bending point of the solder feet located at the lower end face of the housing, the solder feet can reach their maximum length, which greatly increases the suitable height compared to the traditional type. Furthermore, during the manufacturing process, the solder feet are cut according to the height of the raised base to meet the same height requirement for raised connectors of different heights.

[0039] This application provides an 8-pin raised Type-C connector, including a housing 10, an insulating body 20, and a terminal block 30.

[0040] The shell 10 has a pair of vertically downward extending welding feet 14 symmetrically arranged on both sides. The welding feet 14 are formed by bending material from the upper end face 11 of both sides of the shell 10 along the outer side face 12 to the lower end face 13, so that the shell 10 has symmetrical hollowed-out portions 15 on both sides. Specifically, two hollowed-out portions 15 are carved out from the upper end face 11 of both sides of the shell 10 along the outer side face 12 to the lower end face 13. One end of the material produced by the hollowed-out portions 15 is still connected to the lower end face 13 of the shell 10. By bending the two sets of material at the lower end face 13 and folding them vertically downward, a pair of welding feet 14 are formed. The width of a single welding foot 14 is smaller than the width of the hollowed-out portion 15 at that location.

[0041] The soldering lead 14 has a bend 144 located inside the outer side 12 and on the bottom side of the lower end face 13. This allows the soldering lead 14 to reach its maximum length to meet the height requirements of higher-profile connectors, with a maximum height of 4.25mm. During manufacturing, the bent soldering lead 14 can be cut to fit different connector heights.

[0042] The two hollowed-out portions 15 on the upper end face 11 of the housing 10 are not connected, and the housing 10 between the two hollowed-out portions 15 on the upper end face 11 can be sucked and moved by the suction nozzle.

[0043] A reinforcing rib 141 is provided on the welding foot 14. The reinforcing rib 141 is adapted to the curvature of the bend of the welding foot 14. One end of the reinforcing rib 141 is located on the lower end face 13 of the housing 10, and the other end extends to the tail end of the welding foot 14. The reinforcing rib 141 is provided on the welding foot 14. As the welding foot 14 extends out from the lower end face 13 of the housing 10, the reinforcing rib 141 can be a convex strip protruding from both sides of the surface of the welding foot 14, or it can be located on both surfaces of the welding foot 14 with one side concave and the other side convex. In this embodiment, the reinforcing rib 141 is a groove on the outer surface of the welding foot 14 and a convex strip on the inner surface of the welding foot 14. Since only one pair of welding feet 14 provide support on the housing 10, the reinforcing ribs 141 need to be provided on the welding feet 14. By providing the reinforcing ribs 141, the structural strength of the welding feet 141 can be further improved, so that the welding feet 141 can stably support the housing 10 and are less likely to deform or break.

[0044] A first limiting protrusion 16 is provided on the upper inner wall surface of the housing 10, and a second limiting protrusion 17 is provided on the lower inner wall surface of the housing 10. Preferably, there is one first limiting protrusion 16 and two second limiting protrusions 17. A limiting part 18 is provided on the upper edge of the rear end of the housing. Preferably, there are two limiting parts 18 on the left and right sides at the upper edge of the rear end of the housing 10, and the two limiting parts 18 extend towards the middle and bend.

[0045] The housing 10 covers the upper part of the raised base 21 and has two snap-fit ​​portions 19 extending downward on both sides. Preferably, there are two snap-fit ​​portions 19 on the left and right sides.

[0046] Preferably, the distance between the two solder feet 14 is less than the distance between the two snap-fit ​​portions 19. The bend of the solder feet 14 is located on the lower end face 13 of the housing 10, and the plane containing the solder feet 14 is located within the outer side face 12 of the housing 10, thus making the distance between the two solder feet 14 less than the distance between the two snap-fit ​​portions 19. This allows the solder feet 14 to reach their maximum length, which is much greater than the length of solder feet formed by conventional methods, and can meet the height requirements of higher-profile connectors, with a maximum solder foot 14 height of 4.25mm.

[0047] The insulating body 20 includes a raised base 21 and a tongue plate 22 extending from the raised base 21. The raised base 21 and the tongue plate 22 are integrally injection molded. The raised base 21 is a heightened structure. The bottom of the raised base 21 is provided with a fixing post 215 for fixing to the circuit board. The entire connector is stably supported by the solder feet 14 on the housing 10 and the fixing post 215 on the raised base 21. Only one pair of solder feet 14 on the housing 10 provides support, so that the solder feet 14 are not subject to other height restrictions and can reach their maximum length.

[0048] The raised base 21 has a first limiting groove 211 at its upper front edge, and a first limiting protrusion 16 is located in and fixed to the first limiting groove 211. Preferably, there is one first limiting groove 211. The raised base 21 has a second limiting groove 212 at its lower front edge, and a second limiting protrusion 17 is located in and fixed to the second limiting groove 212. Preferably, there are two second limiting grooves 212. The raised base 21 has a third limiting groove 213 recessed on its upper rear surface, and a limiting part 18 is located in and fixed to the third limiting groove 213. Preferably, there are two third limiting grooves 213. The arrangement of the first limiting protrusion 16, the second limiting protrusion 17, the limiting part 18, and the first limiting groove 211, the second limiting groove 212, and the third limiting groove 213 can improve the assembly stability of the housing 10 and the insulating body 20.

[0049] The raised base 21 has stepped portions 214 on both sides of its top, and the two snap-fit ​​portions 19 are tightly snapped into the stepped portions 214. The snap-fit ​​portions 19 and the stepped portions 214 make the fit between the housing 10 and the raised base 21 tighter.

[0050] The terminal group 30 includes two ground terminals, two power terminals, two detection terminals, and two signal terminals. Specifically, the terminal group 30 includes an upper terminal group 30 and a lower terminal group 30. The terminal arrangement of the upper terminal group 30 is a ground terminal A, a power terminal A, and a detection terminal A. The terminal arrangement of the lower terminal group 30 is a ground terminal B, a power terminal B, a first signal terminal B1, a second signal terminal B2, and a detection terminal B. The terminal gaps between the ground terminal A, power terminal A, and detection terminal A are the same as the terminal gaps between the ground terminal B, power terminal B, and detection terminal B. The first signal terminal B1 and the second signal terminal B2 are located between the power terminal B and the detection terminal B of the lower terminal group 30.

[0051] Grounding terminal A, power terminal A, detection terminal A, grounding terminal B, power terminal B, first signal terminal B1, second signal terminal B2, and detection terminal B are placed in a mold, and then plastic is injected into the mold so that all terminals and the insulating body 20 are firmly combined into a whole.

[0052] Each terminal of the terminal group 30 includes an integrally formed terminal body 31, a contact end 32, and a pin end 33, with the terminal body 31 connecting the contact end 32 and the pin end 33. After each terminal of the terminal group 30 is embedded inside the insulating body 20, the contact ends 32 of the ground terminal A, power terminal A, and detection terminal A are exposed on the top surface of the tongue plate 22, while the contact ends 32 of the ground terminal B, power terminal B, first signal terminal B1, second signal terminal B2, and detection terminal B are exposed on the bottom surface of the tongue plate 22. The pin end 33 of each terminal of the terminal group 30 protrudes from the bottom of the raised base 21. The contact ends 32 of the first signal terminal B1 and the second signal terminal B2 are exposed on the bottom surface of the tongue plate 22, allowing the 8-pin raised Type-C connector to transmit data while charging.

[0053] Preferably, the thickness of the terminal group 30 is 2.0mm. The number of terminals of the 8PIN raised Type-C connector is much less than that of the 16PIN connector, and there is more space to accommodate the terminals. Therefore, this application sets the thickness of the terminal group 30 to 2.0mm, and the thicker terminals give it a stronger signal strength.

[0054] The bottom of the soldering foot 14 is provided with a soldering surface 142 and a fixing end 143. The soldering surface 142 is flush with the bottom of the pin end 33 of each terminal of the terminal group 30. The fixing end 143 is fixed to the circuit board together with the fixing post 215 of the raised base 21. This way of fixing the 8PIN raised Type-C connector to the circuit board from both the front and back allows it to be stably supported without shaking. Moreover, the housing 10 and the insulating body 20 are molded separately. The height of the raised base 21 does not limit the maximum length that the soldering foot 14 can reach. Therefore, the soldering foot 14 on the housing 10 and the fixing post 215 on the raised base 21 jointly support and stabilize the entire connector. The maximum length that the soldering foot can reach is much higher than the length of the soldering foot formed by the traditional method, which can meet the height requirements of higher raised connectors. The maximum height of its soldering foot 14 can reach 4.25mm.

[0055] In summary, the key design features of this utility model are:

[0056] By symmetrically arranging a pair of vertically extending solder feet on both sides of the housing of the 8PIN raised Type-C connector, with the bending point of the solder feet located at the lower end face of the housing, the solder feet can reach their maximum length, which greatly increases the suitable height compared to the traditional type. Furthermore, during the manufacturing process, the solder feet are cut according to the height of the raised base to meet the same height requirement for raised connectors of different heights.

[0057] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0058] Although this document frequently uses terms such as shell 10, upper end face 11, outer side face 12, lower end face 13, welding foot 14, reinforcing rib 141, welding surface 142, fixed end 143, bending position 144, hollow part 15, first limiting protrusion 16, second limiting protrusion 17, limiting part 18, snap-fit ​​part 19, insulating body 20, raised base 21, first limiting groove 211, second limiting groove 212, third limiting groove 213, step part 214, fixing post 215, tongue plate 22, terminal group 30, terminal body 31, contact end 32, and pin end 33, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
