[0062] The present invention will be further described in detail below with reference to the accompanying drawings.

[0063] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present invention.

[0064] like Figures 1-23 As shown, the present invention aims to provide a bidirectional switchable USB Type-C side-mount electrical connector, that is, a bidirectional switchable side-mount electrical connector. The overall design scheme is as follows: the first technical solution provides a bidirectional switchable side-mount electrical connector, and the first technical solution provides a method for producing the bidirectional switchable side-mount electrical connector.

[0065] The first technical solution provides a bidirectional switchable side-mount electrical connector, whose main structure is composed of a housing 1, a first insulating support 2, a second insulating support 3, and a conductor group 4. The housing 1, the first insulating support 2, and the second insulating support 3 are sequentially wrapped around the conductor group 4 from the outside to the inside. Furthermore, the housing 1, the first insulating support 2, the second insulating support 3, and the conductor group 4 are all symmetrical structures that are mutually symmetrical along the central plane of the connector, thereby achieving the purpose of bidirectional switching between the front and back sides. There is no need to distinguish the direction when plugging, installing, or manufacturing the surface mount, making operation convenient. Moreover, the symmetrical components simplify the manufacturing process by half, thereby improving production efficiency and reducing production costs.

[0066] A patch notch 11 is provided on one outer side of the housing 1. The portion of the first insulating support 2 corresponding to the patch notch 11 is directly exposed and has a smooth surface. The pick-and-place machine can directly adsorb and grip the connector through the patch notch 11 to install it onto the equipment in a patch-fixed connection manner, which is stable and reliable. There is no need to equip additional patch-mounting auxiliary parts, which further simplifies the production process, saves raw material input, and reduces production costs.

[0067] Furthermore, the extension direction of the input end of conductor group 4 is perpendicular to the extension direction of the output end of conductor group, so that the insertion and removal direction of the input end of the side-mount electrical connector is perpendicular to the insertion and removal direction of the output end; thereby, it can adapt to the connection orientation requirements between charging devices with perpendicular conduction directions.

[0068] Multiple pairs of housing pins 12 are symmetrically arranged at one end of the outer casing 1. During use, the outer casing 1 can be connected to the matching equipment through the multiple pairs of housing pins 12 to ensure that the connection is stable, reliable and will not loosen.

[0069] The corresponding end faces of the first insulating support 2 and the second insulating support 3 are aligned with the root of the housing pin 12, and the corresponding end of the conductor group 4 extends out of the corresponding end faces of the first insulating support 2 and the second insulating support 3, forming a male pin group.

[0070] A female connector cavity is provided at the other end of the outer casing. The corresponding end faces of the first insulating support 2 and the second insulating support 3 are recessed into the bottom of the female connector cavity, and the corresponding ends of the conductor group 4 extend into the female connector cavity to form a female connector pin group.

[0071] An electrical connector consisting of male and female pin groups can be used to transfer power and drive signals.

[0072] Example 1:

[0073] Embodiment 1 provides a bidirectional switchable side-mount electrical connector according to the first technical solution of the present invention.

[0074] The specific structure of Example 1 is as follows:

[0075] The main structure consists of an outer shell 1, a first insulating support 2, a second insulating support 3, and a conductor group 4. The outer shell 1, the first insulating support 2, and the second insulating support 3 are arranged in a sequence from the outside to the inside, covering the conductor group 4. Furthermore, the outer shell 1, the first insulating support 2, the second insulating support 3, and the conductor group 4 are all symmetrical structures that are mutually symmetrical along the central plane of the connector, thereby achieving the purpose of bidirectional switching between the front and back sides. There is no need to distinguish the direction when plugging, installing, connecting, or manufacturing surface mount devices, making operation convenient. Moreover, the symmetrical components simplify the manufacturing process by half, thereby improving production efficiency and reducing production costs.

[0076] A pick-and-place notch 11 is provided on one outer side of the housing 1. The pick-and-place machine can directly pick up the connector through the pick-and-place notch 11 and install it onto the equipment in a fixed pick-and-place manner. This is stable and reliable, and there is no need to equip it with additional pick-and-place auxiliary parts. This further simplifies the production process, saves raw material input, and reduces production costs.

[0077] Furthermore, the extension direction of the input end of conductor group 4 is perpendicular to the extension direction of the output end of conductor group, so that the insertion and removal direction of the input end of the side-mount electrical connector is perpendicular to the insertion and removal direction of the output end; thereby, it can adapt to the connection orientation requirements between charging devices with perpendicular conduction directions.

[0078] Multiple pairs of housing pins 12 are symmetrically arranged at one end of the outer casing 1. During use, the outer casing 1 can be connected to the matching equipment through the multiple pairs of housing pins 12 to ensure that the connection is stable, reliable and will not loosen.

[0079] The corresponding end faces of the first insulating support 2 and the second insulating support 3 are aligned with the root of the housing pin 12, and the corresponding end of the conductor group 4 extends out of the corresponding end faces of the first insulating support 2 and the second insulating support 3, forming a male pin group.

[0080] A Type C plug cavity 13 is provided at the other end of the outer casing 1. The corresponding end faces of the first insulating support 2 and the second insulating support 3 are recessed into the bottom of the Type C plug cavity 13, and the corresponding end of the conductor group 4 extends into the Type C plug cavity 13 to form a Type C pin group.

[0081] This USB Type-C side-mount electrical connector, consisting of male and Type-C pin groups, is a bidirectional switchable connector that can be used to connect power and drive signals.

[0082] The outer shell 1 adopts a symmetrical U-shaped groove structure. Elastic claws 14 are provided on the outer shell 1, and limiting grooves 21 are provided on the outer side of the first insulating support 2. The outer shell 1 is fitted onto the outside of the first insulating support 2 by the cooperation of the elastic claws 14 and the limiting grooves 21. During the assembly process, it is only necessary to insert the cast insulating component into the outer shell through the opening of the U-shaped groove structure and lock it in place by the elastic claws to complete the assembly work. No other auxiliary connection structures and connecting tools are required, which makes the operation convenient and the process simple.

[0083] An avoidance groove 22 is provided on the top surface of the first insulating support 2, and an outwardly protruding limiting plate 23 is provided adjacent to the avoidance groove 22. A U-shaped avoidance groove is also provided on the wall of the outer shell 1 at the corresponding position of the limiting plate, which further facilitates patch installation and improves the stability of the clamping connection with the supporting equipment.

[0084] A locking tab 15 is also provided on the wall of the outer casing corresponding to the Type C insertion cavity 13, which can be locked and limited with the matching connecting device.

[0085] Furthermore, the second insulating support 3 is composed of a first insulating partition 31 and a second insulating partition 32 that are symmetrical to each other; the conductor group 4 is clamped and fixed inside the first insulating support 2 by the first insulating partition 31 and the second insulating partition 32 cooperating with each other.

[0086] The conductor group 4 is composed of a first terminal group 41 and a second terminal group 42 that are symmetrical to each other. The first terminal group 41 is fixedly limited inside the first insulating partition 31, and the second terminal group 42 is fixedly limited inside the second insulating partition 32.

[0087] Specifically, the conductor group includes seven pairs of terminals arranged at intervals, and the seven pairs of terminals consist of fourteen terminals to form a 14P electrical connector; the first terminal group is provided with seven positive terminals, and the second terminal group is provided with seven negative terminals, and both the seven positive terminals and the seven negative terminals are L-shaped terminal blocks;

[0088] The seven terminal pairs include two power terminal pairs, two ground terminal pairs, and three signal control terminal pairs; the male pins of the four terminal pairs located on both sides of the seven terminal pairs are in contact with each other, while the Type C pins are separated from each other by staggered bending.

[0089] Of the seven terminal pairs, the male pins, body, and Type C pins of the three middle terminal pairs are all separated from each other, and the male pins are also increased in spacing by staggered bending, thereby ensuring electrical insulation distance, electrical clearance, and creepage ionization.

[0090] Of the seven terminal pairs, the outermost pair is provided with a limiting boss 4111 and a positioning hole 4112. During production, a limiting pin structure can be formed within the limiting boss 4111 and the positioning hole 4112 through casting. Furthermore, the width of each terminal body is greater than the width of the Type C pin and the male pin, and the widths of the Type C pin and the male pin are equal, ensuring stable and reliable electrical performance. Figures 15-22 As shown.

[0091] Furthermore, a first Type C insulating spacer 33 and a second Type C insulating spacer 34 are provided between all Type C pins of the first terminal group 41 and all Type C pins of the second terminal group 42. The first Type C insulating spacer is fixedly connected to the first insulating partition, and the second Type C insulating spacer is fixedly connected to the second insulating partition. The first and second Type C insulating spacers ensure electrical insulation performance, electrical clearance, creepage distance, and stable and reliable mechanical strength. Figures 13-14 As shown.

The auxiliary support 5 is provided with a limiting slot 51 and a limiting round hole 52. A limiting pin structure can also be formed in the limiting slot 51 and the limiting round hole 52 by casting.
