Description

Technical Field

[0001] This invention relates to a connector assembly and an electrical connector, and more particularly to a connector assembly and an electrical connector capable of reversible insertion. Background Technology

[0002] A conventional connector assembly, such as Chinese Patent CN202021764494.8, includes a wire-end connector and a board-end connector. The wire-end connector has a wire-end housing, a PCB board, and a spring. The spring is fixed in a mounting slot of a first insert plate of the wire-end housing and has a locking hook. The board-end connector has a board-end housing and a socket located within the board-end housing. The board-end housing has a locking hole. When the wire-end connector and the board-end connector are mated, the locking hook of the spring engages with the locking hole of the board-end housing.

[0003] The inventors of this application discovered that because the locking hook of the aforementioned spring is exposed on the outside of the first insert plate, the locking hole needs to span the thickness of the first insert plate and be located on the outside of the first insert plate to lock with the locking hook. This results in the above solution requiring the plate end housing to expand outward relative to the socket so that a mating groove is formed between the plate end housing and the socket to accommodate the first insert plate. However, expanding the plate end housing increases the molding material of the plate end housing. Furthermore, while the aforementioned wire connector and plate end connector can achieve forward insertion, the locking hook and locking hole cannot cooperate during reverse insertion, preventing reverse insertion. To achieve both forward and reverse insertion, both sides of the plate end housing of the plate end connector need to be expanded outward to form mating grooves, further increasing the molding material of the plate end housing.

[0004] Therefore, it is necessary to design a connector assembly and an electrical connector to overcome the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a connector assembly and an electrical connector, which exposes the first locking part of the locking member inside the extension, and the first locking part and the second locking part lock each other between the extension and the mating part, eliminating the need for the second locking part of the second connector to extend outward to the outside of the extension, reducing the molding material of the housing of the second connector, and enabling the first connector and the second connector to be plugged in in opposite directions.

[0006] To achieve the above objectives, the present invention adopts the following first technical solution: a connector assembly, comprising a first connector and a second connector mating with each other along a first direction, the first connector comprising a first insulating body, a locking member, and a transmission member fixed to the first insulating body, one end of the transmission member extending along the first direction to form a mating portion, the transmission member comprising a plurality of first terminals, the first insulating body having a first receiving space and an extension extending along the first direction, the extension having an outer side and an inner side disposed opposite each other along a second direction, the first receiving space being located between the mating portion and the inner side of the extension along the second direction, the locking member being fixed to the extension and having at least one first locking portion, the first locking portion being exposed on the inner side of the extension and spaced from the mating portion through the first receiving space, the first direction and the second direction being perpendicular; the first connector further comprising a connection area for connecting an electronic component, the connection area and the extension being located on both sides of the mating portion along the second direction; the second connector comprising a The system comprises a second insulating body, a metal shell, and a plurality of second terminals fixed to the second insulating body.

The inner surface of the first wall is adjacent to the first side, and the inner surface of the second wall is adjacent to the second side. Both the first wall and the second wall are provided with at least one second locking portion. When the first connector and the second connector are docked, the first terminal and the second terminal are connected. The first wall and the second wall are located on both sides of the docking portion along the second direction, and the first wall or the second wall is received in the first receiving space. The outer surface of the first wall or the outer surface of the second wall faces the inner side of the extension portion. The first locking portion locks with the second locking portion of the first wall or the second locking portion of the second wall. When viewed along the second direction, the projection of the connection area overlaps with the projection of the first wall and the projection of the second wall.

[0007] Furthermore, the extension has a first extension segment and a second extension segment disposed adjacent to the first extension segment. The inner side of the first extension segment is away from the mating portion along the second direction relative to the inner side of the second extension segment. The first locking portion is exposed on the inner side of the first extension segment. When the first connector and the second connector are mated, the inner side of the second extension segment restricts the movement of the first wall or the second wall in the second direction. The first locking portion is located between the inner side of the first extension segment and the first wall or the second wall in the second direction.

[0008] Furthermore, the outer side of the first extension is located away from the mating portion along the second direction relative to the outer side of the second extension, and the locking member includes at least one fixing portion, which is fixed to the first extension.

[0009] Furthermore, the first terminal has a contact portion exposed in the mating portion, a conductive portion located in the connection area and electrically connected to the electronic component, and a connecting portion connecting the contact portion and the conductive portion. The connecting portion extends along the second direction. The contact portion extends from a first end of the connecting portion along the first direction and contacts the second terminal. The conductive portion bends from a second end of the connecting portion toward the contact portion and extends along the second direction. The first insulating body has a receiving portion located in the connection area and for receiving the conductive portion. The receiving portion and the extension portion are located on both sides of the mating portion along the second direction. The first connector also has a second receiving space located between the receiving portion and the mating portion along the second direction. The second receiving space is used to receive at least a portion of the second connector. When viewed along the second direction, the projection of the receiving portion overlaps with the projection of the first locking portion.

[0010] Furthermore, the extension is provided with at least one through hole, which exposes the first locking portion along the second direction. The first locking portion is an opening. After the first connector and the second connector are docked, the second locking portion of the first wall or the second locking portion of the second wall enters the first locking portion.

[0011] Furthermore, the first locking part is an opening, the second locking part is a hook, and there is an elastic deformation space between the inner side of the first locking part and the extension part for the first locking part to move. After the first connector and the second connector are docked, the second locking part is locked in the first locking part, and the second locking part enters the first locking part in the direction of the elastic deformation space.

[0012] Furthermore, in the second connector, the metal shell has at least one first hook arm and at least one second hook arm extending along the second direction. The first hook arm extends beyond the outer surface of the first wall body along the second direction, and the second hook arm extends beyond the outer surface of the second wall body along the second direction. The first insulating body also has a joint located at the connection area, defining a third direction perpendicular to the first and second directions. When viewed along the third direction, the projection of the joint and the projection of the extension are located on both sides of the projection of the mating portion along the second direction. When the first connector and the second connector are mated, the first locking portion locks with the second locking portion of the first wall body, and the second hook arm engages with the joint. The projection of the first hook arm upward along the third direction is completely within the projection of the extension. Alternatively, the first locking portion locks with the second locking portion of the second wall body, and the first hook arm engages with the joint. The projection of the second hook arm upward along the third direction is completely within the projection of the extension.

[0013] Furthermore, the first insulating body is provided with a support portion, the support portion and the inner side of the extension portion are spaced apart from each other, the locking member is also provided with at least one fulcrum and a force-applying portion located outside the extension portion, the fulcrum abuts against the support portion, and viewed along a third direction perpendicular to the first direction and the second direction, the fulcrum is located between the force-applying portion and the first locking portion along the first direction.

[0014] Furthermore, the locking member has a flat plate portion and at least one protrusion protruding from the flat plate portion toward the first receiving space. The fulcrum protrudes from the flat plate portion toward the support portion. The first locking portion is disposed on the protrusion. The support portion has a first surface and a second surface. The first surface is used to abut against the fulcrum. When the first connector and the second connector are mated, the first locking portion locks with the second locking portion of the first wall or the second wall. The second surface faces the first wall or the second wall and restricts the movement of the first wall or the second wall along the first direction. The first surface is close to the extension portion along the second direction relative to the outer surface of the first wall or the second wall.

Compared with the prior art, the connector assembly provided by the present invention has the following beneficial effects: By overlapping the projections of the connection area with the first wall and the second wall, the connection area of ​​the present application will be relatively close to the second connector along the first direction, allowing the connection position of the electronic component to be relatively lowered, which is beneficial to reducing the size of the first connector in the first direction; moreover, since the first locking part is exposed inside the extension and locks with the second locking part entering the first receiving space, that is, the first locking part and the second locking part are locked between the inside of the extension and the mating part, the second locking part... Since the extension portion does not need to extend beyond its thickness to the outside of the extension portion to lock with the first locking portion, the first or second wall of the metal shell of the second connector in this application does not need to be expanded outward relative to the first and second sides to form a receiving space for accommodating the extension portion. The inner surfaces of the first and second walls of this application respectively overlap the first and second sides, reducing the amount of molding material added to the metal shell due to the outward expansion, and enabling the first locking portion to lock with the second locking portion of the first wall, or the first locking portion to lock with the second locking portion of the second wall, thus achieving reversible insertion. Therefore, this application can achieve reversible insertion of the two connectors without affecting the position of the connection area and while reducing the size of the first connector along the first direction.

[0016] To achieve the above objectives, the present invention adopts the following second technical solution: an electrical connector for mating with a docking connector along a first direction, the docking connector having a receiving cavity and mating locking portions located on opposite sides of the receiving cavity, the electrical connector comprising: a transmission member, one end of which extends along the first direction to form a docking portion for receiving in the receiving cavity; an insulating body for fixing the transmission member, the insulating body having a first receiving space and an extension extending along the first direction, the extension having an outer side and an inner side disposed opposite to each other along a second direction, the first receiving space being located between the inner side of the docking portion and the extension along the second direction, the first receiving space being for receiving at least a portion of the docking connector, the second direction being perpendicular to the first direction; a locking member fixed to the extension, the locking member having at least one locking portion exposed on the inner side of the extension, the first receiving space being for receiving the mating locking portion on either side of the docking connector, the locking portion being for locking with the mating locking portion on either side.

[0017] Furthermore, the extension has a first extension segment and a second extension segment disposed adjacent to the first extension segment. The inner side of the first extension segment is away from the mating portion along the second direction relative to the inner side of the second extension segment. The locking portion is exposed on the inner side of the first extension segment and is spaced apart from the inner side of the first extension segment along the second direction.

[0018] Furthermore, the outer side of the first extension is located away from the mating portion along the second direction relative to the outer side of the second extension, and the locking member includes at least one fixing portion, which is fixed to the first extension.

[0019] Furthermore, the extension is provided with at least one through hole, the through hole exposing the latching part along the second direction, the latching part being an opening, the latching part allowing the mating latching part to enter and engage for locking.

[0020] Furthermore, the locking portion is an opening, and there is an elastic deformation space between the inner sides of the locking portion and the extension portion for the locking portion to move, and the locking portion allows the mating locking portion to enter in the direction of the elastic deformation space.

[0021] Furthermore, the electrical connector also includes a connection area for connecting an electronic component, the connection area and the extension being located on opposite sides of the mating portion along the second direction, a second receiving space being provided between the connection area and the mating portion, the second receiving space being used to accommodate at least a portion of the mating connector, and the projection of the connection area and the projection of the locking portion overlapping along the second direction.

[0022] Furthermore, the connection area is used to connect cables, and the electrical connector also includes a mating portion located in the connection area, the mating portion being used to engage with the hook arm of the mating connector.

[0023] Furthermore, the distance between the joint portion and the mating portion along the second direction is defined as the first distance, and the distance between the outer side of the extension portion and the mating portion along the second direction is defined as the second distance, wherein the first distance is not greater than the second distance.

[0024] Furthermore, the insulating body is provided with a support portion, which is spaced apart from the inner side of the extension portion. The locking member is also provided with at least one fulcrum and a force-applying portion located outside the extension portion. The fulcrum abuts against the support portion. When viewed along a third direction perpendicular to the first direction and the second direction, the fulcrum is located between the force-applying portion and the locking portion along the first direction.

[0025] Furthermore, the locking member has a flat plate portion and at least one protrusion protruding from the flat plate portion toward the first receiving space. The fulcrum protrudes from the flat plate portion toward the support portion. The locking portion is disposed on the protrusion. The protrusion dimension of the fulcrum along the second direction is smaller than the protrusion dimension of the protrusion along the second direction. The support portion has a first surface and a second surface.

[0027] Compared with the prior art, the electrical connector provided by the present invention has the following beneficial effects: Since the locking part is exposed on the inner side of the extension and locks with the mating locking part on either side, that is, the locking part and the mating locking part are locked between the inner side of the extension and the mating part, the mating locking part does not need to cross the thickness of the extension to the outer side of the extension to lock with the locking part. Therefore, this application does not require the mating connector to extend the mating locking part to the outer side of the extension, which can reduce the molding material increase of the mating connector due to the extension, and can realize the locking part locking with the mating locking part on either side, realizing the positive and negative insertion of the electrical connector and the mating connector.

[0029] Explanation of reference numerals in the accompanying drawings for the specific implementation methods: Detailed Implementation To facilitate a better understanding of the purpose, structure, features, and effects of this invention, the invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0030] To facilitate a better understanding of the technical solution of the present invention, the Z-axis in the three-dimensional coordinate axes in the accompanying drawings is defined as the first direction, the Y-axis as the second direction, and the X-axis as the third direction. The X-axis, Y-axis, and Z-axis are mutually perpendicular to each other.

[0031] Please see Figures 1 to 4 This invention provides a connector assembly comprising a first connector 100 and a second connector 200 mating together along a first direction Z. The first connector 100 and the second connector 200 are also respectively connected to a first electronic component 300 and a second electronic component. In this embodiment, the first electronic component 300 is a cable, and the second electronic component (not shown, the same below) is a circuit board. Of course, in other embodiments, the first electronic component 300 and the second electronic component can be other components, for example, the first electronic component 300 is a circuit board and the second electronic component is a cable, or the first electronic component 300 is a cable and the second electronic component is a cable; this is not limited here. It should be noted that, as can be understood, when the first connector 100 is called an electrical connector, the second connector 200 is the mating connector of the first connector 100 (electrical connector). The first connector 100 has a connection area Q for connecting the first electronic component 300. After the first connector 100 and the second connector 200 are mated, they achieve mutual locking and signal transmission, and can be unlocked and separated through an unlocking operation.

[0032] Please see Figure 1 and Figure 3The first connector 100 includes a first insulating body 1, a locking member 3, a pull strap 5, and a transmission member 2 and an inner mold 4 fixed to the first insulating body 1. The pull strap 5 is sleeved on the locking member 3. The transmission member 2 and the locking member 3 are both fixed to the first insulating body 1. The transmission member 2 has a plurality of first terminals 22. The transmission member 2 includes a mating portion 21 extending from the first insulating body 1 along a first direction Z. In this embodiment, at least a portion of the transmission member 2 is housed within the first insulating body 1. The plurality of first terminals 22 are arranged in two rows and are respectively exposed on the two surfaces of the mating portion 21. The first terminals 22 are used to connect the first electronic component 300 and the second connector 200. The inner mold 4 is housed within the first insulating body 1 and used to fix the connection position between the first terminals 22 and the first electronic component 300 to increase the connection stability between the first terminals 22 and the first electronic component 300. In this embodiment, the first insulating body 1 includes a separate first body 15 and a second body 16. The transmission component 2 is assembled and fixed to the first body 15, and the second body 16 is used to cover and fix the transmission component 2 to the first body 15 after assembly. In other embodiments, the first insulating body 1 can be a one-piece structure. In use, the user can directly pull the pull strap 5 to deform the locking member 3, or the user can directly press the force application part 34 of the locking member to deform the locking member 3, so as to unlock the first connector 100 and the second connector 200 from each other.

[0033] Please see Figure 2 and Figure 3The second connector 200 includes a second insulating body 7, a metal shell 8, and a plurality of second terminals 9 fixed to the second insulating body 7. The second insulating body 7 has a receiving cavity 6, and the plurality of second terminals 9 are arranged in two rows on both sides of the receiving cavity 6. The second insulating body 7 has a first side 71 and a second side 72 disposed opposite to each other along the second direction Y. The metal shell 8 has a first wall 81 and a second wall 82 disposed opposite to each other along the second direction Y. The inner surface of the first wall 81 is adjacent to the first side 71, and the inner surface of the second wall 82 is adjacent to the second side 72. Both the first wall 81 and the second wall 82 are provided with two second locking parts 83 (or mating locking parts). It can be understood that the second locking parts 83 are respectively located on opposite sides of the receiving cavity 6 of the second connector 200. It should be noted that there is no receiving space between the inner surface of the first wall 81 and the first side surface 71 for accommodating the related structure of the first connector 100 along the first direction Z, and there is no receiving space between the inner surface of the second wall 82 and the second side surface 72 for accommodating the related structure of the first connector 100 along the first direction Z. However, the inner surface of the first wall 81 and the first side surface 71 may be completely fitted together, or there may be a certain gap due to assembly or other needs; similarly, the inner surface of the second wall 82 and the second side surface 72 may be completely fitted together, or there may be a certain gap due to assembly or other needs. Furthermore, the metal shell 8 also has two first hook arms 84 and two second hook arms 85 extending along the second direction Y, the first hook arms 84 extending beyond the outer surface of the first wall 81 along the second direction Y, and the second hook arms 85 extending beyond the outer surface of the second wall 82 along the second direction Y. It should be noted that the second locking portion 83 of the second connector 200 is provided on the first wall 81 and the second wall 82 of the metal shell 8. In other embodiments, the second connector 200 may not have a metal shell 8 and may be replaced by an insulating shell, with the second locking portion 83 located on both sides of the insulating shell; or the second locking portion 83 may be formed directly from both sides of the second insulating body 7. In this embodiment, the second connector 200 also has two guide grooves 86 located on both sides of the receiving cavity 6 along the third direction X, and the two guide grooves 86 are used to receive the two guide posts 19 of the first connector 100.

[0034] Please see Figures 3 to 6 , Figure 11The first insulating body 1 has a first receiving space G1 and an extension 11 extending along the first direction Z. The extension 11 has an outer side 115 and an inner side 114 disposed opposite each other along the second direction Y. The first receiving space G1 is located between the docking portion 21 and the inner side 114 of the extension 11 along the second direction Y. The connecting area Q and the extension 11 are respectively located on both sides of the docking portion 21 along the second direction Y. The extension 11 has a first extension segment 111 and a second extension segment 112 disposed adjacent to the first extension segment 111. In this embodiment, the extension 11 has two second extension segments 112 located on the first extension segment 111 along the third direction X. In other embodiments, the number of the first extension segment 111 and the second extension segment 112 of the extension 11 can be set according to actual needs. The first insulating body 1 also has two guide posts 19 extending along the first direction Z, and the two guide posts 19 are respectively located on both sides of the docking portion 21 along the third direction X.

[0035] Please see Figure 1 , Figure 3 and Figure 11 The locking member 3 is fixed to the extension 11. The locking member 3 has two first locking parts 321 (or locking parts). The first locking parts 321 are exposed on the inner side 114 of the extension 11 and are spaced apart from the docking part 21 through the first receiving space G1.

[0036] Please see Figures 3 to 7When the first connector 100 and the second connector 200 are successfully mated, the first terminal 22 and the second terminal 9 are aligned, and the first wall 81 and the second wall 82 are located on either side of the mating portion 21 along the second direction Y. Alternatively, if the first connector 100 and the second connector 200 are connected in the forward orientation, after mating, the first wall 81 is received in the first receiving space G1, with its outer surface facing the inner side 114 of the extension portion 11, and the first locking portion 321 is locked to the second locking portion 83 of the first wall 81. If the first connector 100 and the second connector 200 are connected in the reverse orientation, after mating, the second wall 82 is received in the first receiving space G1, with its outer surface facing the inner side 114 of the extension portion 11, and the first locking portion 321 is locked to the second locking portion 83 of the second wall 82. That is, the first accommodating space G1 is used to accommodate the second locking part 83 on either side of the second connector 200, and the first locking part 321 is used to lock with the second locking part 83 on either side. Therefore, in the technical solution of this application, since the first locking part 321 is exposed on the inner side 114 of the extension 11 and locks with the second locking part 83 entering the first accommodating space G1, that is, the first locking part 321 and the second locking part 83 are locked between the inner side 114 of the extension 11 and the mating part 21, so that the second locking part 83 does not need to cross the thickness of the extension 11 to the outer side 115 of the extension 11 to lock with the first locking part 321, the inner surface of the first wall 81 and the second wall of this application... The inner surface of body 82 can respectively cover the first side 71 and the second side 72, without the first wall 81 or the second wall 82 being expanded outward relative to the first side 71 and the second side 72 to form a receiving space for accommodating the extension 11, thereby reducing the amount of molding material added to the metal shell 8 due to the outward expansion. Moreover, this application can achieve the locking of the first locking part 321 with the second locking part 83 of the first wall 81, or the locking of the first locking part 321 with the second locking part 83 of the second wall 82, and can also achieve the reversible insertion of the two connectors.

[0037] Please see Figure 5 , Figure 6 and Figure 10When the first connector 100 and the second connector 200 are docked, when viewed along the second direction Y, the projection of the connection area Q overlaps with the projections of the first wall 81 and the second wall 82. Therefore, relative to the projections of the connection area Q being offset from those of the first wall 81 and the second wall 82, the connection area Q of this application can be relatively close to the second connector 200 along the first direction Z, allowing the connection position of the first electronic component 300 to be relatively lowered, which is beneficial for reducing the size of the first connector 100 in the first direction Z. Furthermore, it is understood that if the metal shell 8 of the second connector 200 expands outward to lock with the first locking portion 321 exposed on the outer side 115 of the extension 11, during reverse insertion, the lowered connection area Q of the expanded first wall 81 or second wall 82 will block the reverse insertion, preventing it from being achieved. To achieve both forward and reverse insertion, the technical solution of expanding outward to form a receiving space to receive the extension 11 cannot include the lowered connection area Q. In this application, the first locking part 321 is exposed on the inner side 114 of the extension 11 to lock the second locking part 83. The first wall 81 and the second body 16 of the metal shell 8 do not need to expand outwards to form a receiving space. Regardless of whether the insertion is forward or reverse, the first wall 81 and the second wall 82 will not collide with the sunken connection area Q. Therefore, this application can achieve both forward and reverse insertion between the first connector 100 and the second connector 200 without affecting the setting of the connection area Q, thus meeting the requirement to reduce the size of the first connector 100 along the first direction Z. Those skilled in the art can set the sunken connection area Q according to actual needs. That is, in other embodiments, if there is no need to reduce the size of the first connector 100 along the first direction Z, the projection of the connection area Q of the first connector 100 along the second direction Y may not overlap with the projections of the first wall 81 and the second wall 82.

[0038] Furthermore, such as Figure 5 , Figure 6 and Figure 10As shown, the connecting area Q and the extension 11 are located on opposite sides of the mating portion 21 along the second direction Y. A second accommodating space G2 is provided between the connecting area Q and the mating portion 21. The second accommodating space G2 is used to accommodate at least a portion of the second connector 200. Along the second direction Y, the projection of the connecting area Q overlaps with the projection of the first locking portion 321. Thus, the second accommodating space G2 between the connecting area Q and the mating portion 21 allows the connecting area Q to restrict the movement of the second connector 200 after mating, increasing the connection stability between the first connector 100 and the second connector 200. When the connecting area Q sinks down to overlap with the projection of the first locking portion 321, compared to when it does not sink down to the first locking portion 321, this application has more area to restrict the movement of the second connector 200 and effectively reduces the size of the first connector 100 in the first direction Z.

[0039] Please see Figure 11In this embodiment, the inner side 114 of the first extension segment 111 is away from the docking portion 21 along the second direction Y relative to the inner side 114 of the second extension segment 112. The first locking portion 321 is exposed on the inner side 114 of the first extension segment 111. After the first connector 100 and the second connector 200 are docked, the inner side 114 of the second extension segment 112 restricts the movement of the first wall 81 or the second wall 82 along the second direction Y. The first locking portion 321 is located between the inner side 114 of the first extension segment 111 and the first wall 81 or the second wall 82 along the second direction Y. Understandably, when the first locking part 321 and the second locking part 83 of the first wall 81 are locked together, the first locking part 321 is located between the inner side 114 of the first extension 111 and the first wall 81 along the second direction Y; when the first locking part 321 and the second locking part 83 of the second wall 82 are locked together, the first locking part 321 is located between the inner side 114 of the first extension 111 and the second wall 82 along the second direction Y. Thus, the inner side 114 of the first extension 111 is relatively far from the docking part 21, freeing up space for the first locking part 321 to prevent the locking member 3 from obstructing the second connector 200 from entering the first receiving space G1 and facilitating the arrangement of the first locking part 321 on the inner side 114 of the first extension 111; by having the inner side 114 of the second extension 11 close to the docking part 21, the movement of the second connector 200 can be restricted to maintain a stable docking between the first connector 100 and the second connector 200. In this embodiment, the locking part is spaced apart from the inner side 114 of the first extension 111 along the second direction Y. There is an elastic deformation space G3 between the locking part and the inner side 114 of the extension 11 for the first locking part 321 to move. Thus, the inner side 114 of the first extension 111 is away from the docking part 21, making room for the elastic deformation space G3 and the first locking part 321, and preventing the locking part 3 from interfering with the insertion of the second connector 200.

[0040] Furthermore, such as Figure 1 and Figure 3 , Figure 13 and Figure 14As shown, the outer side 115 of the first extension segment 111 is farther away from the docking portion 21 along the second direction Y relative to the outer side 115 of the second extension segment 112. The locking member 3 includes two fixing portions 36, which are fixed to the first extension segment 111. Thus, the first extension segment 111 has a certain thickness for the fixing portions 36 to fix it. Meanwhile, the outer side 115 of the second extension segment 112 is closer to the docking portion 21 relative to the outer side 115 of the first extension segment 111, rather than being flush with the outer sides 115 of the first and second extension segments 112. This reduces the thickness of the second extension segment 112 and avoids deformation due to uneven heat dissipation during molding caused by a larger thickness of the second extension segment 112.

[0041] Please see Figure 13 and Figure 14 The locking member 3 also includes a flat plate portion 31, two protrusions 32, a force-applying portion 34, a bent portion 35 connecting the force-applying portion 34 and the flat plate portion 31, and two fulcrums 33. In this embodiment, the two first locking portions 321 are respectively located at the two protrusions 32, and the force-applying portion 34 is located outside the extension portion 11. The locking member 3 also includes two limiting portions 37 and two elastic abutment arms 38, the elastic abutment arms 38 extending toward the inner side 114 of the extension portion 11 and abutting against the inner side 114 of the extension portion 11. Figure 8 As shown, the two limiting portions 37 are received in the limiting groove 116 of the extension portion 11, and the limiting groove 116 has a first groove surface and a second groove surface arranged opposite to each other along the second direction Y. The two fixing portions 36 of the locking member 3 are respectively located on both sides of the force-applying portion 34.

[0042] In this embodiment, when the force-applying part 34 is subjected to force, the first locking part 321 is pried and deformed along the second direction Y in a direction away from the docking part 21. The elastic abutting arm 38 is pressed against the inner side 114 of the extension part 11 and abuts against the inner side 114 of the extension part 11. The limiting part 37 moves toward the first groove surface of the limiting groove 116. The first groove surface of the limiting groove 116 limits the degree of deformation of the locking member 3. When the force applied to the force-applying part 34 decreases, the elastic abutting arm 38 provides a restoring force for reset. The first locking part 321 gradually moves and resets, and the limiting part 37 moves beyond the second groove surface of the limiting groove 116. In addition, in this embodiment, the limiting groove 116 penetrates the extension 11 in the direction of the force-applying part 34. The locking member 3 can also be gradually guided into the limiting groove 116 by the limiting part 37 to pre-fix the position between the locking member 3 and the extension 11. After further assembly, it is fixed to the extension 11 by the fixing part 36, thereby fixing the locking member 3 to the extension 11. In this embodiment, the fixing part 36 extends from the flat plate part 31 by bending, forming a U-shaped arm to fasten and fix to the extension 11.

[0043] In other embodiments, the locking member 3 may not necessarily be specially provided with the elastic support arm 38, and may also be provided with a U-shaped structure to provide restoring force; the fixing part 36 may not necessarily be a U-shaped arm, and may be other fixing structures; the limiting part 37 may also be provided or removed according to actual needs.

[0044] Please see Figure 1 , Figure 3 , Figure 7 and Figure 9The extension 11 has two through holes 113, which expose two first locking portions 321 along the second direction Y. The first locking portions 321 are open, allowing the second locking portions 83 to enter and engage for locking. After the first connector 100 and the second connector 200 are docked, the second locking portion 83 of the first wall 81 enters the first locking portion 321 to lock the first locking portion 321 with the second locking portion 83 of the first wall 81; or the second locking portion 83 of the second wall 82 enters the first locking portion 321 to lock the first locking portion 321 with the second locking portion 83 of the second wall 82. Therefore, the relative positions of the first locking part 321 and the second locking part 83 can be easily observed through the through hole 113. Moreover, the first locking part 321 is an opening, which allows for further observation of whether the second locking part 83 enters or exits the opening, making it easier to determine whether the first locking part 321 and the second locking part 83 have successfully locked or unlocked.

[0045] Please see Figure 7In this embodiment, the first locking part 321 is an opening, and the second locking part 83 is a hook. An elastic deformation space G3 is provided between the first locking part 321 and the inner side 114 of the extension 11, allowing the first locking part 321 to move. After the first connector 100 and the second connector 200 are connected, the second locking part 83 is engaged with the first locking part 321, and the second locking part 83 enters the first locking part 321 towards the elastic space. It should be noted that if the first locking part 321 is a hook and the second locking part 83 is an opening, the hook may pass through the opening and collide with the second insulating body 7, causing damage to the second insulating body 7. To avoid damage to the second insulating body 7 by the hook, a clearance groove needs to be cut into the second insulating body 7 to accommodate the hook, or a clearance gap needs to be formed between the first wall 81 and the first side 71. This would increase the structural design complexity of the second connector 200. In this application, the first locking portion 321 is an opening, and the second locking portion 83 is a hook. This allows the elastic deformation space G3, originally designed for the deformation of the locking member 3, to simultaneously accommodate the hook. This prevents the hook from colliding with the second insulating body 7 and does not affect the structural design of the second connector 200. Furthermore, in other embodiments, when the first locking portion 321 is an opening, the second locking portion 83 may not be a hook; it can be any other structure, as long as it can enter the open first locking portion 321 towards the elastic deformation space G3 and be stopped and limited by the opening. Of course, in other embodiments, the first locking portion 321 may not be an opening.

[0046] Please see Figures 5 to 7The first insulating body 1 is provided with a support portion 12, which is spaced apart from the inner side 114 of the extension portion 11. Two fulcrums 33 abut against the support portion 12. Viewed along the third direction X, the fulcrums 33 are located between the force-applying portion 34 and the first locking portion 321 along the first direction Z. Thus, when the force-applying portion 34 is subjected to force, the fulcrums 33 can abut against the support portion 12. The fulcrums 33 cause the force-applying portion 34 and the first locking portion 321 to elastically deform through the lever principle, which facilitates unlocking. Furthermore, the fulcrum 33 protrudes from the flat plate portion 31 toward the support portion 12, and the protrusion 32 protrudes toward the first receiving space G1 relative to the flat plate portion 31. The support portion 12 has a first surface 121 and a second surface 122. The first surface 121 is used to abut against the fulcrum 33. When the first connector 100 and the second connector 200 are mated, the first locking portion 321 locks itself with the second locking portion 83 of the first wall body 81 or the second wall body 82. The second surface 122 faces the first wall body 81 or the second wall body 82 and restricts the movement of the first wall body 81 or the second wall body 82 along the first direction Z. The first surface 121 is closer to the extension portion 11 along the second direction Y relative to the outer surface of the first wall body 81 or the second wall body 82. It can be understood that the closer the first surface 121 is to the extension portion 11, meaning that the protrusion dimension of the fulcrum 33 along the second direction Y is smaller than the protrusion dimension of the protrusion 32 along the second direction Y. Compared to the hypothetical solution where the locking member 3 does not have a protrusion 32 and the first locking part 321 is directly provided on the flat part 31, in this application, the first locking part 321 is provided on the protrusion 32, so that the first locking part 321 actively moves closer to the second locking part 83, without the first wall 81 or the second wall 82 needing to expand outward to approach and cooperate with the position of the first locking part 321, thus reducing the volume of the metal shell 8; at the same time, the support part 12 can protrude relative to the first wall 81 or the second wall 82 toward the fulcrum 33, increasing the material thickness of the support part 12, increasing the strength of the support part 12, and preventing the support part 12 from being broken by the fulcrum 33. In addition, in some application scenarios, the first wall 81 or the second wall may collide with the second surface 122 (for example, when the design specifically requires the first wall 81 or the second wall 82 to collide with the second surface 122, or when the first wall 81 or the second wall 82 collides with the second surface 122 due to molding tolerances). Increasing the strength of the support portion 12 can also prevent the support portion 12 from being damaged by the collision with the second connector 200.

[0047] Please see Figure 5 and Figure 6 The force-applying part 34 extends away from the connection area Q relative to the flat plate part 31. The first insulating body 1 has a clearance space 13, which is disposed adjacent to the support part 12 along the first direction Z. The clearance space 13 is used to accommodate the bending part 35 and the force-applying part 34 when the force-applying part 34 deforms in the direction of the connection area Q under force. Since the force-applying part 34 deforms in the direction of the connection area Q under force, and the fulcrum 33 is located on the flat plate part 31, the force-applying part 34 of this application extends away from the connection area Q, which can better pry the locking member 3 around the fulcrum 33, and facilitates the formation of the clearance space 13. It is beneficial to accommodate the bending part 35 and the force-applying part 34 through the clearance space 13, and avoids the first insulating body 1 restricting the elastic deformation of the locking part.

[0048] Please see Figure 5 and Figure 6 The first terminal 22 has a contact portion 221 exposed in the mating portion 21, a conductive portion 223 located in the connection area Q and electrically connected to the first electronic component 300, and a connecting portion 222 connecting the contact portion 221 and the conductive portion 223. The connecting portion 222 extends along the second direction Y. The contact portion 221 extends from the first end of the connecting portion 222 along the first direction Z and contacts the second terminal 9. The conductive portion 223 bends from the second end of the connecting portion 222 toward the contact portion 221. The first insulating body 1 has a receiving portion 14 located at the connection location Q and used to receive the conductive portion 223. The receiving portion 14 and the extension portion 11 are located on both sides of the mating portion 21 along the second direction Y. The second receiving space G2 is located between the receiving portion 14 and the mating portion 21 along the second direction Y. The second receiving space G2 receives at least a portion of the second connector 200. When viewed along the second direction Y, the projection of the receiving portion 14 overlaps with the projection of the first locking portion 321. Thus, the first terminal 22 can contact the second terminal 9 in the first direction Z and conduct to the first electronic component 300 in the second direction Y, making the first connector 100 a vertically oriented connector; the projection of the receiving portion 14 of this application overlaps with the projection of the first locking portion 321, that is, the space of the receiving portion 14 will sink down to at least the first locking portion 321, increasing the sinking degree of the receiving portion 14 and effectively reducing the size of the first connector 100 along the first direction Z; at the same time, the receiving portion 14 can restrict the movement of the second connector 200 along the second direction Y.

[0049] It should be noted that in this embodiment, the transmission component 2 is formed by injection molding of insulating material and first terminal 22. In other embodiments, the transmission component 2 may take other forms, which are not limited here. For example, the transmission component 2 may be formed by assembling and inserting insulating material and first terminal 22; or the transmission component 2 may be a circuit board, with the first terminal 22 etched and fixed to the substrate of the circuit board by etching a metal plating material; or the connecting part of the first terminal 22 may be a wire, connecting the contact part 221 and the conductive part 223. In this embodiment, the transmission component 2 and the first insulating body 1 are separately formed. In other embodiments, the transmission component 2 may be integrally injection molded with the first insulating body 1. Furthermore, in other embodiments, the transmission component 2 may directly provide the mating part to connect with the first insulating body 1 through integral injection molding or snap-fit, etc. The transmission component 2 does not necessarily need to include a part housed inside the first insulating body 1.

[0050] Please see Figures 10 to 12The first insulating body 1 also has a joint portion 17 located at the connection location Q. When viewed along the third direction X, the projection of the joint portion 17 and the projection of the extension portion 11 are located on both sides of the projection of the mating portion 21 along the second direction Y. After the first connector 100 and the second connector 200 are mated, the first locking portion 321 is locked with the second locking portion 83 of the first wall 81, and the second hook arm 85 is fastened to the joint portion 17. The projection of the first hook arm 84 along the third direction X is completely within the projection of the extension portion 11. Alternatively, after the first connector 100 and the second connector 200 are mated, the first locking portion 321 is locked with the second locking portion 83 of the second wall 82, and the first hook arm 84 is fastened to the joint portion 17. The projection of the second hook arm 85 along the third direction X is completely within the projection of the extension portion 11. In this application's technical solution, since the metal shell 8 of the second connector 200 does not need to expand outward to form a receiving space to accommodate the extension 11, and the material of the metal shell 8 does not extend to cover the outer side 115 of the extension 11, the metal shell 8 cannot resist the hanging load force at the connection location Q by mutually restricting the extension 11. However, this application can increase the docking stability between the first connector 100 and the second connector 200 by cooperating with the joint 17 through the first hook arm 84 or the second hook arm 85 when the connection location Q is subjected to a hanging load force (for example, when the electronic component is a cable, the cable sinking and the hanging load will have a pulling force on the connection location Q), thus preventing the first connector 100 and the second connector 200 from separating. And since the projection of the second hook arm 85 is completely located within the projection of the extension 11 along the third direction X, the setting of the first hook arm 84 and the second hook arm 85 does not increase the size of the first and second connectors 200 along the second direction Y after docking. Understandably, the distance between the joining portion 17 and the mating portion 21 along the second direction Y is defined as the first distance D1, and the distance between the outer side 115 of the extension portion 11 and the mating portion 21 along the second direction Y is defined as the second distance D2, where the first distance D1 is not greater than the second distance D2. Therefore, after either the first hook arm 84 or the second hook arm 85 mates with the joining portion 17, the other hook arm 84 will not extend beyond the outer side 115 of the extension portion 11, reducing the size of the connector assembly along the second direction Y after mating.

[0051] Please see Figure 1 , Figure 10 and Figure 11The first insulating body 1 also has a limiting plate 18. After the first connector 100 and the second connector 200 are mated, the limiting plate 18 restricts the second wall 82 or the first wall 81 from moving along the second direction Y. In addition, when the first locking part 321 is an opening and the second locking part 83 is a hook, the inner side of the limiting plate 18 is also provided with a clearance groove 181. When the first locking part 321 is locked with the second locking part 83 of the first wall 81, the clearance groove 181 is located in the second locking part 83 of the second wall 82; when the first locking part 321 is locked with the second locking part 83 of the second wall 82, the clearance groove 181 is located in the second locking part 83 of the first wall 81.

[0052] It should be noted that in this embodiment, the metal shell 8 of the second connector 200 has a first hook arm 84 and a second hook arm 85 on both sides, which can prevent the first connector 100 and the second connector 200 from detaching due to the weight of the load during both forward and reverse insertion. However, in other embodiments, only the first hook arm 84 or only the second hook arm 85 may be provided, that is, only one side may have a hook arm that cooperates with the joint portion 17. The user can determine whether to insert forward or reverse based on whether there is a weight problem in the actual usage scenario. For example, in some usage environments, when the first electronic component 300 is a cable, if the cable will not sag to exert a large pulling force on the connection area Q under the current usage environment, it is permissible not to have the joint portion 17 and the corresponding hook arm cooperate.

[0053] It should be noted that the number of the first locking part 321, the through hole 113, the fixing part 36, the elastic supporting arm 38, the fulcrum 33, and the limiting part 37 are not limited to two in this embodiment. The number of the second locking part 83 on each side is also not limited to two in this embodiment. They can all be set to one or more according to actual needs.

[0054] In summary, the connector assembly and electrical connector of the present invention have the following beneficial effects: 1. Since the first locking part 321 is exposed on the inner side 114 of the extension 11 and locks with the second locking part 83 that enters the first accommodating space G1, it is not necessary for the first wall 81 or the second wall 82 to expand outward relative to the first side 71 and the second side 72 respectively to form an accommodating space for accommodating the extension 11, thereby reducing the amount of molding material added to the metal shell 8 due to the outward expansion. Moreover, this application can achieve the locking of the first locking part 321 with the second locking part 83 of the first wall 81, or the locking of the first locking part 321 with the second locking part 83 of the second wall 82, and can also achieve the reversible insertion of the two connectors.

[0055] 2. This application further provides a connection area Q that is close to the second connector 200 along the first direction Z. This application can realize the forward and reverse insertion between the first connector 100 and the second connector 200 without affecting the setting of the connection area Q, and can meet the requirement of reducing the size of the first connector 100 along the first direction Z.

[0056] 3. The through hole 113 of the extension 11 facilitates observation of the relative positions of the first locking part 321 and the second locking part 83. Moreover, when the first locking part 321 is open, it is possible to further observe whether the second locking part 83 enters the opening or exits the opening.

[0057] 4. The first locking part 321 is an opening and the second locking part 83 is a hook. This allows the elastic deformation space G3, which was originally designed for the deformation of the locking part 3, to simultaneously accommodate the hook. This prevents the hook from colliding with the second insulating body 7 and also avoids affecting the structural design of the second connector 200.

[0058] 5. The first hook arm 84 or the second hook arm 85 engages with the joint portion 17 to increase the stability of the connection between the first connector 100 and the second connector 200, preventing them from detaching. Since the projection of the second hook arm 85 along the third direction X is entirely within the projection of the extension portion 11, the provision of the first hook arm 84 and the second hook arm 85 does not increase the size of the first and second connectors 200 along the second direction Y after connection.

[0059] The above detailed description is only an illustration of a preferred embodiment of the present invention and is not intended to limit the patent scope of the present invention. Therefore, all equivalent technical changes made using the content of this invention's specification and illustrations are included within the patent scope of this invention.
