Description

Technical Field

[0001] The invention relates to the field of electrical connectors, and in particular to a hermaphroditic electrical connector. Background Art

[0002] In order to keep the electrical connector low and thin the device, a horizontal connector was developed. A horizontal connector is an electronic component whose pins or contact parts (metal terminals) are mounted parallel to the surface of the circuit board. This installation method not only saves space, but also allows the connector to maintain a low height while providing a stable electrical connection. It has been widely used in automotive electronics and medical electronics, providing efficient and reliable electrical connections for these devices.

[0003] Existing horizontally attached connectors are usually modularized when used, that is, a number of horizontally attached connectors are connected to the circuit board side by side in a certain order. In order to facilitate the connection between the complementary terminals of adjacent horizontally attached connectors, the male terminal and the female terminal on the same horizontally attached connector are usually arranged on the same side for connecting with the complementary terminal. However, this method has great limitations, and the male terminal and the female terminal between adjacent horizontally attached connectors are not tightly matched, resulting in unstable matching between the horizontally attached connectors.

[0006] Furthermore, the portion of the first terminal exposed outside the first insertion cavity through the first opening forms a first mating end, and the first mating end has elastic force outward and inward through the first opening, which is used to elastically resist against the second terminal of an adjacent male and female electrical connector.

[0007] Furthermore, the first mating end is configured as an arc structure that bends outward through the first opening; in a natural state, the top of the arc structure is exposed outside the first opening; when elastically abutting against the second terminal of an adjacent hermaphroditic electrical connector, the top of the arc structure elastically abuts against the second terminal exposed outside the second opening or the top of the arc structure extends into the second opening of the adjacent hermaphroditic electrical connector and elastically abuts against the second terminal; in a state of abutment under force, the top of the arc structure elastically deforms toward the first opening.

[0008] Furthermore, the portion of the second terminal exposed outside the second insertion cavity through the second opening forms a second mating end, and the second mating end is used to elastically abut against the first mating end of the first terminal of an adjacent hermaphroditic electrical connector.

[0009] Furthermore, an inclined extrusion section is formed at the end of the second mating end, and the inclined extrusion section is inclined inwardly relative to the second opening when the second terminal is inserted into the second insertion cavity; a limiting inclined surface matched with the second insertion cavity is formed at a position corresponding to the inclined extrusion section, and the limiting inclined surface is used to block the end of the second terminal from exiting the second insertion cavity when the inclined extrusion section is inserted into the second insertion cavity; when the second mating end is abutted by the first mating end of the first terminal of the adjacent male and female homologous electrical connector, the inclined extrusion section is subjected to force and presses against the bottom wall of the second insertion cavity along the limiting inclined surface.

[0010] Furthermore, a stop portion is extended on both sides of the second mating end along its width direction, and a limiting groove is formed between the stop portion and the second mating end for facing the opening on one side of the second opening, and the limiting groove is used for the curved structure of the adjacent male and female electrical connector to extend into and be limited therein.

[0011] Furthermore, a bottom wall is formed on one side of the first insertion cavity close to the second insertion cavity, the first insertion cavity is penetrated in a direction away from the second insertion cavity to form the first opening, the first insertion cavity penetrates two opposite side surfaces of the plastic body along the insertion direction of the first terminal to respectively form a first through-opening and a second through-opening, and the first through-opening is connected to the first opening; the first terminal also has a first insertion section inserted into the first insertion cavity and a first welding end extending out of the first insertion cavity through the first through-opening; the first insertion section includes a first straight section tightly attached to the bottom wall of the first insertion cavity and a curved arc section connected between the first straight section and the first mating end, the curved arc section is away from the first welding end, and the curved arc section is exposed outside the first insertion cavity through the second through-opening, and the second through-opening has a closing portion for limiting the curved arc section from passing out of the second through-opening.

DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] The hermaphroditic electrical connector of the present invention is a part of a modular connector and is a horizontally attached connector. A plurality of identical hermaphroditic electrical connectors are sequentially connected and matched along an assembly direction to form a modular connector.

[0030] Please refer to Figures 1 to 9The hermaphroditic electrical connector of the present invention comprises a plastic body 1, a first insertion cavity 2 opened on the plastic body 1, a second insertion cavity 3 opened on the plastic body 1, a first terminal 4 inserted in the first insertion cavity 2, and a second terminal 5 inserted in the second insertion cavity 3. The plastic body 1 is used to protect the first terminal 4 and the second terminal 5. The first terminal 4 and the second terminal 5 are used to realize the transmission of electrical signals to realize the electrical connection between the connector and the complementary connector and the same hermaphroditic electrical connector.

[0031] Please refer to Figures 1 to 5 , Figures 8 to 9 The plastic body 1 is made of plastic injection molding. The plastic body 1 is similar to a rectangular parallelepiped structure and has length, width, and height (or thickness). The plastic body 1 has two end faces distributed along its length direction, a first side face 11 and a second side face 12 that are oppositely distributed along its width direction, and a third side face 13 and a fourth side face 14 that are distributed along its height direction. The fourth side face 14 is used for connecting and mating with a complementary connector. For this purpose, the fourth side face 14 is a flat surface that facilitates contact and mating with the complementary connector. The third side surface 13 is used for installation and use with a circuit board. In order to avoid affecting the use between adjacent male and female electrical connectors, each circuit board is preferably arranged parallel to the first side surface 11 and the second side surface 12. For this reason, the ends of the first terminal 4 and the second terminal 5 used for welding with the circuit board are preferably distributed one high and one low relative to the plastic body 1 in the height direction of the plastic body 1 to be welded to the circuit board. For this reason, in order to facilitate the placement of the first terminal 4 and the second terminal 5, the third side surface 13 is divided into a first side surface 131 and a second side surface 132. The first side surface 131 is arranged close to the first side surface 11 and higher than the second side surface 132, and the second side surface 132 is arranged close to the second side surface 12 and lower than the first side surface 131. In order to support the part where the first terminal 4 and the second terminal 5 are welded to the circuit board, a middle portion 113 is protruded along the height direction of the plastic body 1 at the part of the third side surface 13 located between the first side surface 131 and the second side surface 132. The first side surface 11 and the second side surface 12 are respectively used for contacting and cooperating with the same and adjacent hermaphroditic electrical connectors. To this end, the first side surface 11 and the second side surface 12 are both flat surfaces so as to abut against the plastic body 1 of the adjacent hermaphroditic electrical connector to ensure the stability of the modular connector.

[0032] In the content defined in this embodiment, the side of the middle part 113 facing the second side surface 12 along the width direction of the plastic body 1 is defined as a contact surface 15, and the contact surface 15 is used for the circuit board to contact and cooperate with it to ensure the stability of the circuit board and the plastic body 1 after the first terminal 4 and the second terminal 5 are welded. On both end surfaces of the plastic body 1, a convex portion 16 is formed by extending in the opposite direction along the length direction of the plastic body 1, and the convex portion 16 is respectively adjacent to the first side surface 11, the third side surface 13 and the fourth side surface 14 and is flush with each other, and the side of the convex portion 16 corresponding to the contact surface 15 is flush with the contact surface 15 and is defined as a part of the contact surface 15. T-shaped mounting holes 161 are opened through the two convex portions 16 along the width direction of the plastic body 1, and the side close to and penetrating the contact surface 15 is a narrow section, and the side close to and penetrating the first side surface 11 is a wide section. A metal-supported pull tab 162 is inserted into the mounting hole 161. The pull tab 162 is adapted to the mounting hole 161 and is T-shaped. On the portion of the pull tab 162 corresponding to the narrow section and on both sides along the width direction of the pull tab 162, a serrated protrusion is provided. The protrusion is adapted to the inner wall of the narrow section of the mounting hole 161, so that when the pull tab 162 is inserted into the narrow section, the protrusion is pressed against the inner wall of the mounting hole 161. When the wide end of the pull tab 162 is inserted into the wide section, the other end of the pull tab 162 passes out of the contact surface 15 to facilitate welding on the circuit board and play the role of pulling the circuit board, so that the connection between the circuit board and the male and female electrical connector is more secure. In order to prevent mistakes, a positioning column 163 is provided on the contact surface 15 where the protruding portion 16 is located. The positioning column 163 corresponds to the positioning hole structure on the circuit board, so as to facilitate quick positioning and prevent direction errors, and play a certain role in preventing mistakes. In this embodiment, the pull tab 162 and the positioning column 163 are defined as auxiliary connecting members to improve the connection stability between the plastic body 1 and the circuit board. In this embodiment, the protruding portion 16, the mounting hole 161, the pull tab 162 and the positioning column 163 are collectively defined as auxiliary connecting members.

[0033] In this embodiment, the first insertion cavity 2 and the second insertion cavity 3 are respectively opened on the plastic body 1 along the width direction of the plastic body 1. In order to facilitate the installation of the first terminal 4 and the second terminal 5, the first insertion cavity 2 and the second insertion cavity 3 are both opened and formed from the third side surface 13 along the height direction of the plastic body 1. Among them, the first insertion cavity 2 is opened and formed from the first side surface 131, and the second insertion cavity 3 is opened and formed from the second side surface 132. In order to facilitate the first terminal 4 and the second terminal 5 to respectively match with the adjacent hermaphroditic electrical connector, the first insertion cavity 2 and the second insertion cavity 3 penetrate the first side surface 11 and the second side surface 12 of the plastic body 1 in the directions away from each other along the width direction of the plastic body 1, so that the first insertion cavity 2 forms a first opening 21 on the first side surface 11, and the first opening 21 is far away from the second insertion cavity 3, so that the second insertion cavity 3 forms a second opening 31 on the second side surface 12, and the second opening 31 is far away from the first insertion cavity 2. To facilitate the installation of the first terminal 4 and the second terminal 5, the first insertion cavity 2 penetrates the first side surface 131 along the height direction of the plastic body 1 to form a first through-opening 22, and the first insertion cavity 2 penetrates the fourth side surface 14 along the height direction of the plastic body 1 to form a second through-opening 23. The first through-opening 22 is provided on two opposite sides of the plastic body 1, and the first through-opening 22 is communicated with the first opening 21, so that the first terminal 4 can be inserted into the first insertion cavity 2 from the first through-opening 22 along the height direction of the plastic body 1. The second insertion cavity 3 penetrates the second side surface 132 along the height direction of the plastic body 1 to form a third through-opening 32, and the first through-opening 22 is communicated with the second opening 31, so that the second terminal 5 can be inserted into the second insertion cavity 3 from the third through-opening 32 along the height direction of the plastic body 1. In this embodiment, the moving direction of inserting the first terminal 4 and the second terminal 5 into the plastic body 1 along the height direction of the plastic body 1 is defined as the insertion direction of the first terminal 4 and the second terminal 5. The first terminal 4 is exposed outside the first insertion cavity 2 through the first opening 21, so that the first terminal 4 is exposed relative to the outer cavity of the first insertion cavity 2 through the first opening 21, so that the second terminal 5 of the adjacent hermaphroditic electrical connector can be abutted against the first terminal 4 through the first opening 21; the second terminal 5 is exposed outside the second insertion cavity 3 through the second opening 31, so that the second terminal 5 is exposed relative to the outer cavity of the second insertion cavity 3 through the second opening 31, so that the first terminal 4 of another adjacent hermaphroditic electrical connector can be abutted against the second terminal 5 through the second opening 31.

[0034] Please refer to Figures 1 to 9, the first terminal 4 and the second terminal 5 are both made of conductive metal such as copper to facilitate the transmission of electrical signals. The first terminal 4 includes a first mating end 41 corresponding to the first opening 21, a first insertion section 42 for being inserted into the first insertion cavity 2, and a first welding end 43 extending out of the first insertion cavity 2 through the first through opening 22 during installation. During assembly, the first insertion section 42 is inserted into the first insertion cavity 2, the first mating end 41 is located at the first opening 21 and is exposed outside the first insertion cavity 2 by facing the first opening 21 in the width direction of the plastic body 1. Due to the elastic characteristics of the material of the first terminal 4 itself, the first mating end 41 has an elastic force through the first opening 21 to the outside or inside of the first insertion cavity 2, so as to be elastically supported by the second terminal 5 of the male and female electrical connector adjacent to the first side surface 11, so as to facilitate the conduction of electrical signals, and the first welding end 43 extends toward the contact surface 15 side for adaptation, so as to be used for welding with the circuit board.

[0035] The first mating end 41 extends from the first insertion section 42 along the height direction of the plastic body 1 from the fourth side 14 toward the third side 13, and the middle portion of the first mating end 41 is bent and convexly arranged along the width direction of the plastic body 1 toward the side away from the first insertion section 42 to form an arc structure 411. The arc structure 411 is used to bend and convexly arrange to the outside of the first insertion cavity 2 through the first opening 21 after the first terminal 4 is installed, and the arc structure 411 extends out of the first insertion cavity 2 through the first opening 21.

[0036] In this embodiment, in the natural state, the top of the arc structure 411 (i.e., the side of the arc structure 411 away from the first insertion section 42 along the width direction of the plastic body 1) is exposed outside the first opening 21; when elastically abutting against the second terminal 5 of an adjacent hermaphroditic electrical connector, the top of the arc structure 411 extends into the second opening 31 of an adjacent hermaphroditic electrical connector and elastically abuts against the second terminal 5 of the adjacent hermaphroditic electrical connector; in the abutting force state, the top of the arc structure 411 is squeezed and deformed relative to the natural state and moves inward through the first opening 21 until the abutting state is maintained until the two hermaphroditic electrical connectors are in contact, and the electrical signal is maintained through the abutment between the first terminal 4 and the second terminal 5 of the two hermaphroditic electrical connectors. In another embodiment, the first mating end 41 may also be only a straight structure or still be a curved structure 411, but the top of the curved structure 411 away from the first insertion section 42 passes through the first opening 21, and the first mating end 41 extends from the first insertion section 42 along the height direction of the plastic body 1 relatively from the fourth side 14 to the third side 13 and tilts toward the side away from the first insertion section 42. After the first insertion section 42 is inserted into the first insertion cavity 2, the first mating end 41 extends out of the first insertion cavity 2 through the first opening 21 and is used to abut against the second terminal 5 of the adjacent hermaphroditic electrical connector, or the top of the curved structure 411 elastically abuts against the second terminal 5 exposed outside the second opening 31 of the adjacent hermaphroditic connector. Under the abutting force state, the top of the curved structure 411 produces elastic deformation toward the first opening 21.

[0037] In the content defined in this embodiment, the first insertion section 42 includes a first straight section 421 extending along the height direction of the plastic body 1 and a curved section 422 integrally connected to the first straight section 421, the curved section 422 is bent from one end of the first straight section 421 toward the fourth side surface 14 along the width direction of the plastic body 1, and the middle part of the curved section 422 is curved and convex along the height direction of the plastic body 1 toward the side away from the first straight section 421. The first mating end 41 is integrally connected to one end of the curved section 422 away from the first straight section 421, the curved section 422 provides support for the first mating end 41, and the curved section 422 provides elasticity to the first mating end 41, so that the first mating end 41 can move relative to the first opening 21 into the first insertion cavity 2 or toward the outer shape of the first insertion cavity 2 after being squeezed or released from squeezing. In order to adapt to the first insertion end 41, the first insertion cavity 2 includes a first insertion cavity section 24 and a second insertion cavity section 25 which are sequentially distributed along the width direction of the plastic body 1, wherein the first insertion cavity section 24 is located on the side close to the first side surface 11, the first opening 21 is formed in the first insertion cavity section 24, and the second insertion cavity section 25 is located on the side close to the second insertion cavity 3. In order to ensure that the first insertion section 42 can be relatively stable after being inserted into the first insertion cavity 2, a first tight fitting portion 423 in a serrated or barbed shape is protruded on both sides of the first straight section 421 along the width direction of the first straight section 421, and the width direction of the first straight section 421 corresponds to the length direction of the plastic body 1. Therefore, in order to make the first insertion cavity 2 adapt thereto, the second insertion cavity section 25 is widened relative to the first insertion cavity section 24 and adapted to the first tight fitting portion 423. In order to avoid the insertion depth of the first insertion section 42 and to avoid the cavity wall of the first insertion cavity 2 from causing unnecessary extrusion on the first insertion section 42, the first straight section 421 is extended and widened in the opposite direction along the length direction of the plastic body 1 on both sides of the width direction of the first straight section 421 at one end away from the curved section 422 to have a first widened portion 424, and the overall width of the first widened portion 424 is wider than the overall width of the first tight-fitting portion 423. Correspondingly, the second insertion cavity section 25 continues to widen toward one side of the third side surface 13 and is adapted to the first widened portion 424 to form a first widened cavity section 26, and for this purpose, the connection between the first widened cavity section 26 and the second insertion cavity section 25 is stepped. The first welding end 43 is integrally connected to the end of the first straight section 421 away from the curved section 422, that is, the first welding end 43 is connected to the first widened portion 424.During assembly, the curved section 422 is aligned with the first plug-in cavity section 24, and the first straight section 421 is inserted into the first widened cavity section 26 along the insertion direction (i.e., the height direction of the plastic body 1) until the first widened portion 424 stops in the first widened cavity section 26. At this time, the first tight-fitting portion 423 presses against the inner wall of the second plug-in cavity section 25, and the curved section 422 faces the second through-hole 23 and is exposed outside the first insertion cavity 2, so that the complementary terminal of the complementary connector can extend into the first insertion cavity 2 through the second through-hole 23 and abut against the curved section 422. Correspondingly, the second through-hole 23 has a widened section connected to the first insertion cavity 2 and a closed portion 231 narrower than the widened section. The closed portion 231 ensures that the curved section 422 is exposed outside the first insertion cavity 2, and the length of the closed portion 231 is less than the overall length of the curved section 422 in the width direction of the plastic body 1. However, since the two ends of the curved section 422 are curved toward the third side surface 13, the curved section 422 can be narrowed as a whole after being squeezed, and the closed portion 231 plays a role in limiting the curved section 422 from passing out of the second through-hole 23 to a certain extent. In this embodiment, the side of the second insertion cavity section 25 away from the first opening 21 is defined as the bottom wall. After the first straight section 421 is inserted into the first insertion cavity 2, the first straight section 421 is distributed in close contact with the bottom wall, so that the curved section 422 can provide support for the first mating end 41. The second insertion cavity section 25 is formed from the middle portion 113 through the height direction of the plastic body 1; the first insertion cavity section 24 and the second insertion cavity section 25 penetrate the third side surface 13 on one side as the first through-hole 22, and the opening side of the closing portion 231 is the second through-hole 23. In another embodiment, the entire second insertion cavity section 25 can be defined as the bottom wall of the first insertion cavity 2.

[0038] The first welding end 43 extends from the first straight section 421 along the height direction of the plastic body 1 and then bends to include a first inclined section 431 connected to the first straight section 421 and a first welding leg 432 integrally connected to the first inclined section 431 and bent from the first inclined section 431 to extend along the height direction of the plastic body 1 toward a side away from the first straight section 421. The bending portion where the first welding leg 432 is connected to the first inclined section 431 corresponds to the contact surface 15, so that when the circuit board is matched with the contact surface 15, the first welding leg 432 contacts the circuit board and is welded to the circuit board.

[0039] Please refer to Figures 1 to 9In this embodiment, the second terminal 5 includes a second mating end 51 corresponding to the second opening 31, a second insertion section 52 for being inserted into the second insertion cavity 3, and a second welding end 53 extending out of the second insertion cavity 3 through the third through hole 32 during installation. During assembly, the second insertion section 52 is inserted into the second insertion cavity 3 along the insertion direction, the second mating end 51 is located at the second opening 31 and is exposed outside the second insertion cavity 3 facing the second opening 31 in the width direction of the plastic body 1. After the first side surface 11 of the hermaphroditic electrical connector adjacent to the second side surface 12 contacts it, the first mating end 41 of the first terminal 4 of the adjacent hermaphroditic electrical connector is elastically supported against the second mating end 51 through the second opening 31, and the conduction of the electrical signal is achieved through the elastic force of the adjacent first mating end 41. The second welding end 53 extends toward the side of the contact surface 15 to adapt to be used for welding with the circuit board together with the first welding.

[0040] The second mating end 51 extends from the second insertion section 52 along the height direction of the plastic body 1 from the third side 13 to the fourth side 14, and an inclined limiting section 511 is formed at the end of the second mating end 51 away from the second insertion section 52. The inclined limiting section 511 extends from the second mating end 51 along the height direction of the plastic body 1 toward the side away from the second mating end 51 after being bent and inclined inwardly. The inner side of the second mating end 51 here refers to the side of the second mating end 51 facing the first insertion cavity 2 after being assembled in the second insertion cavity 3, so that the inclined limiting section 511 is inclined inwardly when the second mating end 51 is inserted in the second insertion cavity 3. In the content defined in this embodiment, in order to ensure the stability of the electrical signal conduction between the first terminal 4 and the second terminal 5 when the second mating end 51 elastically abuts against the first mating end 41 of the adjacent hermaphroditic electrical connector, a stopper 512 is formed on both sides of the second mating end 51 along the width direction consistent with the width direction of the third straight section 522 and extending in the reverse direction along the length direction of the plastic body 1. The thickness of the two stoppers 512 along the width direction of the plastic body 1, that is, the thickness direction of the second mating end 51, is greater than the thickness of the second mating end 51, and the two stoppers 512 protrude from the second mating end 51 in the thickness direction of the second mating end 51 toward the side away from the third straight section 522, so that an open limiting groove 513 is formed between the two stoppers 512 and the second mating end 51.

[0041] In this embodiment, after the second mating end 51 is assembled in the second insertion cavity 3, the entire second mating end 51 is located in the second insertion cavity 3 so as to be located inside the second opening 31. Due to the existence of the second opening 31, the second mating end 51 is exposed outside the plastic body 1, so that the adjacent first mating end 41 can elastically abut against it through the second opening 31. The curved structure 411 of the adjacent first mating end 41 extends into the limiting groove 513 after passing through the second opening 31, and the two stoppers 512 limit the curved structure 411. The structure 411 moves in the width direction of the second mating end 51 to ensure that the arc structure 411 does not deflect or squeeze, thereby ensuring a stable electrical connection between the arc structure 411 and the second mating end 51. When the arc structure 411 contacts and gradually squeezes the second mating end 51, the limiting groove 513 is restricted by the limiting groove 513 and slides to a certain extent along the height direction of the plastic body 1 relative to the limiting groove 513 and deforms toward the first insertion cavity 2 where it is located. For this reason, the limiting groove 513 has a certain guiding effect.

[0042] In this embodiment, the second insertion section 52 includes a second straight section 521 extending along the height direction of the plastic body 1, and a third straight section 522 integrally connected to one end of the second straight section 521 facing the fourth side surface 14 and extending along the width direction of the plastic body 1 after being bent from the second straight section 521. The third straight section 522 is assembled in the second insertion cavity 3 facing the second side surface 12 and then extends toward the side away from the first insertion cavity 2. The second mating end 51 is formed by bending from one end of the third straight section 522 away from the second straight section 521. The second welding end 53 is integrally connected to one end of the second straight section 521 away from the third straight section 522, and the second straight section 521 and the second mating end 51 are formed by extending in the opposite direction relative to the third straight section 522 along the height direction of the plastic body 1. In order to ensure the stability between the second insertion section 52 and the second insertion cavity 3, a second tight fitting portion 523 with a sawtooth loading hook is formed on both sides of the third straight section 522 in the width direction. The width direction of the third straight section 522 is the same as the width direction of the first straight section 421, so that after the third straight section 522 is inserted into the second insertion cavity 3, it is pressed against the cavity wall of the second insertion cavity 3, so that the second insertion section 52 is not easy to fall off, and the possibility of the second terminal 5 falling off during the installation of the circuit board is reduced to simplify the operation. In order to increase the tightness and stability between the second straight section 521 and the second insertion cavity 3, a second widening portion 524 is formed on both sides of the second straight section 521 in the width direction of the third straight section 522, which is convexly formed along the length direction of the plastic body 1, so as to facilitate the tight fit with the second insertion cavity 3, increase the contact surface area 15 and improve the stability. It should be noted that the inclined limit section 511 is not provided with a stopper 512. In the present embodiment, the second welding end 53 is bent from one end of the second straight section 521 away from the third straight section 522 to include a second inclined section 531 connected to the second straight section 521 and a second welding leg 532 integrally connected to the second inclined section 531 and bent from the second inclined section 531 to extend along the height direction of the plastic body 1 toward a side away from the third straight section 522. The first welding leg 432 and the second welding leg 532 both extend in the same direction and are collinear and are collectively referred to as welding legs. The first welding leg 432 and the second welding leg 532 do not interfere with each other and are located on the same welding surface. The second welding leg 532 is close to the middle portion 113 along the height direction of the plastic body 1, and the first welding leg 432 is located on the side away from the middle portion 113 and is spaced apart from the second welding leg 532.

[0043] In this embodiment, in order to adapt to the second terminal 5, the second insertion cavity 3 includes a third insertion cavity section 33 opened from the middle part 113 along the height direction of the plastic body 1, a fourth insertion cavity section 34 opened from the second side surface 132 along the height direction of the plastic body 1, and a fifth insertion cavity section 35 opened from the second side surface 132 along the height direction of the plastic body 1. The third insertion cavity section 33 is located on the side close to the second side surface 12 along the width direction of the plastic body 1, the second insertion cavity section 25 is located on the side close to the first side surface 11, and the third insertion cavity section 33 is adapted to the second widened portion 524. Since the second inclined section 531 is bent and inclined from the second widened portion 524, in order to facilitate the second inclined section 531 not to be obstructed, the third plug cavity section 33 is provided with an avoidance cavity section 331 on the side of the middle portion 113 away from the first side surface 11 along the width direction of the plastic body 1. The avoidance cavity section 331 is connected to the third plug cavity section 33 and is narrower than the third plug cavity section 33. The avoidance cavity section 331 passes through the middle portion 113 along the height direction of the plastic body 1 toward the side away from the fourth side surface 14, so that the second terminal 5 can be inserted therein along the height direction of the plastic body 1. The side of the avoidance cavity section 331 close to the first plug cavity 2 is defined as the bottom wall of the second plug cavity 3, and the entire third plug cavity section 33 can also be the bottom wall of the second plug cavity 3. The length direction of the fourth plug cavity section 34 is distributed along the width direction of the plastic body 1, the depth of the fourth plug cavity section 34 is adapted to the third straight section 522, and the second tight fitting portion 523 is used to fit therein. The fifth plug cavity section 35 is formed from the second side surface close to the second side surface 12, and the fifth plug cavity section 35 passes through the second side surface 12 along the width direction of the plastic body 1 to form a second opening 31, and the fifth plug cavity section 35 is connected to the fourth plug cavity section 34. In order to facilitate matching with the inclined limiting section 511, a triangular cavity is recessed on the side of the fifth plug cavity section 35 away from the fourth plug cavity section 34, and a limiting inclined surface 351 matching with the inclined limiting section 511 is formed on the side of the cavity close to the second opening 31. The limiting slope 351 is used to prevent the second mating end 51 and the inclined limiting section 511 from being in contact with the limiting slope 351 when the second mating end 51 and the inclined limiting section 511 are inserted into the fifth plug-in cavity section 35. When the inclined limiting section 511 contacts the limiting slope 351, the inclined limiting slope 351 presses the inclined limiting section 511 inward along the inclined direction of the limiting slope 351, so that the second mating end 51 is pressed tightly and the second mating end 51 is restricted from exiting the second insertion cavity 3. Since the second mating end 51 is affected by the elastic characteristics of the second terminal 5 itself, the second terminal 5 has a certain elasticity and is easy to pop out of the second insertion cavity 3 through the second opening 31. The cooperation between the limiting slope 351 and the inclined limiting section 511 well avoids this possibility. When the second mating end 51 is held by the first mating end 41 of the first terminal 4 of an adjacent male and female electrical connector, the inclined section is forced to move toward the bottom wall of the second insertion cavity 3 along the limiting slope 351.

[0044] Please refer to Figure 8 and Fig. 9 One embodiment of the hermaphroditic electrical connector of the present invention works as follows: two identical hermaphroditic electrical connectors are prepared and arranged in sequence along the width direction of the plastic body 1, so that the first mating end 41 of the first terminal 4 of one of the hermaphroditic electrical connectors passes through the second opening 31 of the other hermaphroditic electrical connector to extend into the limiting groove 513 of the second terminal 5 to achieve abutment, and the mating between the two hermaphroditic electrical connectors is completed, and the first mating end 41 and the second mating end 51 extend back to back and mate back to back, so as to facilitate the mating between a plurality of hermaphroditic electrical connectors.
