[0016] In one embodiment, the first insertion slot includes a first sub-insertion slot and a second sub-insertion slot, the first sub-insertion slot and the second sub-insertion slot are arranged at a distance from each other along a second direction;

[0017] The second insertion slot includes a third sub-insertion slot and a fourth sub-insertion slot, which are arranged at intervals relative to each other along the second direction;

[0018] The third sub-insertion slot is located between the first sub-insertion slot and the second sub-insertion slot, and the second sub-insertion slot is located between the third sub-insertion slot and the fourth sub-insertion slot.

[0019] In one embodiment, the first sub-insertion slot, the second sub-insertion slot, and the third sub-insertion slot are arranged at equal intervals along the second direction, and the second sub-insertion slot, the third sub-insertion slot, and the fourth sub-insertion slot are arranged at equal intervals along the second direction.

[0020] And / or, the first housing has a slot, and the second housing includes a plug-in portion and a mounting portion, the plug-in portion being used for plugging into the slot, and the mounting portion being used for mounting the auxiliary mounting component.

[0021] In one embodiment, the auxiliary mounting component includes a base and two connecting portions, the two connecting portions being respectively disposed on both sides of the base along a second direction, the mounting portions engaging with each connecting portion on both sides along a first direction, and the mounting portions engaging with each connecting portion on both sides along the second direction.

[0022] And / or, the auxiliary mounting component is provided with a support groove, the support groove is provided in multiple ways and is respectively located on both sides of the insertion part along the second direction, the mounting part is provided with a plurality of support members, the plurality of support members are inserted into the plurality of support grooves one by one to pre-tighten the puncture part located in the insertion part;

[0023] The free end of the support member is arranged in an inward arc shape.

[0024] In one embodiment, the mounting part is provided with a plurality of first fasteners on both sides along the second direction, and each connecting part is provided with a plurality of first fastener slots, wherein the plurality of first fasteners engage with the plurality of first fastener slots one by one.

[0025] And / or, the mounting part is provided with second snap-fit ​​grooves on both sides along the first direction, and the connecting part is provided with second snap-fit ​​members on both sides along the first direction, the second snap-fit ​​members engaging with the second snap-fit ​​grooves.

[0030] The technical solution of this invention involves arranging multiple male terminals spaced apart along a first direction, and each female terminal having a piercing portion and a contact portion. The multiple contact portions are connected to the multiple male terminals one by one, resulting in the multiple female terminals being spaced apart along the first direction at the contact portions. With the piercing portion width greater than the contact portion, adjacent piercing portions are stacked and spaced apart, allowing the piercing portions of adjacent female terminals to be closer together. This reduces the distance between any two adjacent female terminals, thereby reducing the width of the multiple female terminals arranged on the second housing, thus reducing the size of the plug assembly. The width of the socket assembly is reduced because the width of the multiple female terminals arranged on the second housing is reduced, and the spacing between the multiple male terminals that mate with the multiple female terminals is also reduced. This reduces the width of the socket assembly, allowing for a smaller size through a closer arrangement between adjacent female terminals. Furthermore, by having at least two piercing sub-parts spaced along the second direction for each piercing portion, each female terminal can be pierced and connected to the wire through at least two piercing sub-parts, making the connection between the female terminal and the wire more stable. In the automotive connector field, this is beneficial for the assembly and use of piercing connectors in confined spaces. Attached Figure Description

[0050] In modern automotive manufacturing, the rapid and precise installation of connectors plays a crucial role in improving vehicle assembly efficiency and ensuring circuit reliability. To achieve this, many automotive connectors integrate sophisticated guiding and positioning features to ensure accurate mating during assembly. However, despite significant advancements in ease of installation, there is still room for further optimization in miniaturization design.

[0051] This invention proposes a piercing connector with a flat overall structure, which is used for wiring connections in automotive headlight power supplies. By reducing the size of the piercing connector, the space occupied by the connector for wiring is reduced.

[0052] Please see Figures 1 to 11In one embodiment of the present invention, the piercing connector 100 includes a socket assembly 10, a plug assembly 20, and an auxiliary mounting member 30. The socket assembly 10 includes a first housing 11 and a plurality of male terminals 12 disposed within the first housing 11, the plurality of male terminals 12 being spaced apart along a first direction. The plug assembly 20 includes a second housing 21 and a plurality of female terminals 22 disposed within the second housing 21. The second housing 21 is inserted into the first housing 11. Each female terminal 22 includes a piercing portion 221 and a contact portion 222. The contact part 222 is mated with one of the plurality of male terminals 12. The piercing parts 221 of adjacent female terminals 22 are stacked and spaced apart. Each piercing part 221 includes at least two piercing sub-parts 221a. The at least two piercing parts 221 are spaced apart along a second direction. Each piercing part 221 is used to connect a wire through the at least two piercing sub-parts 221a. The first direction and the second direction are intersected. The auxiliary mounting member 30 is provided on the second housing 21 and is used to fix the plurality of female terminals 22 to the second housing 21.

[0053] In this invention, the first direction can be the width direction of the piercing connector 100, and the second direction can be the thickness direction of the piercing connector 100. The piercing connector 100 may further include a circuit board 200. A first housing 11 can be fixed to the circuit board 200, and multiple male terminals 12 disposed on the first housing 11 can be connected to the power receiving terminals of the circuit board 200. The multiple male terminals 12 and multiple female terminals 22 are mated together. A clamping portion can be provided at the end of the power receiving portion 222 of the female terminal 22 near the male terminal 12. When the second housing 21 is inserted into the first housing 11, the clamping portion of each female terminal 22 clamps the corresponding male terminal 12, enabling the plug assembly 20 and the socket assembly 10 to achieve a power connection. The multiple male terminals 12 can be spaced apart along the width direction of the socket assembly 10, making the socket assembly 10 flat. The multiple female terminals 22 can be spaced apart along the width direction of the plug assembly 20, making the plug assembly 20 flat as well, resulting in an overall flat structure for the piercing connector 100.

[0054] like Figure 2 , Figure 8 As shown, when the first housing 11 is mounted to the circuit board 200, a plurality of positioning posts 114 can be provided at the bottom of the first housing 11, and positioning holes that engage with the positioning posts 114 are provided on the circuit board 200, so that the first housing 11 can be accurately positioned at the designated mounting position on the circuit board 200, thereby facilitating the connection between the male terminal 12 and the circuit board 200. In addition, when the male terminal 12 is mounted on the first housing 11, a insertion groove 1111 can be provided at the end of the first housing 11 away from the second housing 21, and the male terminal 12 is inserted into the slot 111 of the first housing 11 through the insertion groove 1111.

[0055] The multiple male terminals 12 are spaced apart along the width direction of the piercing connector 100, meaning there are gaps between adjacent male terminals 12 to prevent electrical continuity between them. Since the contact portion 222 of the female terminal 22 is connected to the male terminal 12, the contact portions 222 of the multiple female terminals 22 can also be spaced apart along the width direction of the piercing connector 100. Thus, while ensuring that the gap between two adjacent male terminals 12 prevents short circuits, the overall width of the socket assembly 10 can be reduced by decreasing the distance between adjacent male terminals 12, thereby reducing the overall width of the multiple male terminals 12 after installation.

[0056] When the distance between two adjacent male terminals 12 is reduced, the distance between the contact portions 222 of two adjacent female terminals 22 will also decrease. Since the piercing portion 221 of the female terminal 22 is used to pierce the insulation layer of the wire and to make electrical connection to the internal metal layer of the wire, the width of the piercing portion 221 of the female terminal 22 must be greater than the width of its contact portion 222. When the distance between the contact portions 222 of two adjacent female terminals 22 is reduced, in order to prevent the piercing portions 221 of the adjacent female terminals 22 from interfering with each other, the piercing portions 221 of the two adjacent female terminals 22 can be arranged in a stacked manner with intervals. For example, the piercing portions 221 of the two adjacent female terminals 22 can overlap to a certain extent in the thickness direction and the width direction of the piercing connector 100. As long as there is a gap between them, it can be ensured that the adjacent female terminals 22 will not be short-circuited. This reduces the overall size of the multiple female terminals 22 after they are installed and arranged in the second housing 21, thereby reducing the width of the plug assembly 20. The overall size of the piercing connector 100 can be reduced without decreasing the total number of electrical terminals. When the female terminal 22 pierces the insulation layer of the wire through the piercing part 221 to make an electrical connection with the wire, to improve the stability of the connection between the piercing part 221 and the wire, the piercing part 221 can have at least two piercing sub-parts 221a, and these at least two piercing sub-parts 221a can be spaced apart along the thickness direction of the piercing connector 100. By having a single piercing part 221 have multiple piercing sub-parts 221a, a single female terminal 22 can pierce multiple positions of the wire through the multiple piercing sub-parts 221a, allowing the single female terminal 22 to be connected and fixed to the wire at multiple positions, thus ensuring the stability of the connection between the female terminal 22 and the wire.

[0057] The technical solution of the present invention arranges multiple male terminals 12 at intervals along a first direction, and each female terminal 22 has a piercing portion 221 and a contact portion 222. The multiple contact portions 222 are connected to the multiple male terminals 12 one by one, so that the multiple female terminals 22 are arranged at intervals along the first direction at the positions of the contact portions 222. When the width of the piercing portion 221 is greater than that of the contact portion 222, the adjacent piercing portions 221 are arranged in a stacked and spaced manner, allowing the piercing portions 221 of adjacent female terminals 22 to be closer together. This reduces the distance between any two adjacent female terminals 22, thereby reducing the width of the arrangement of the multiple female terminals 22 on the second housing 21, thus reducing [the burden on the system]. The width of the plug assembly 20 is reduced because the width of the multiple female terminals 22 arranged on the second housing 21 is reduced, and the spacing between the multiple male terminals 12 that mate with the multiple female terminals 22 is also reduced. This reduces the width of the socket assembly 10, allowing for a smaller size of the piercing connector 100 through a closer arrangement between adjacent female terminals 22. Furthermore, by having each piercing portion 221 have at least two piercing sub-portions 221a spaced apart along the second direction, each female terminal 22 can be pierced and connected to the wire through at least two piercing sub-portions 221a, making the connection between the female terminal 22 and the wire more stable. In the field of automotive connectors, this is beneficial for the assembly and use of the piercing connector 100 in confined spaces.

[0058] See Figure 10 , Figure 11 As shown, in one embodiment, the plurality of female terminals 22 include a plurality of first female terminals 22a and a plurality of second female terminals 22b, wherein each first female terminal 22a and each second female terminal 22b are disposed adjacent to each other;

[0059] The piercing portion 221 of the first female terminal 22a is bent and connected to the electrical contact portion 222, and the piercing portion 221 of the first female terminal 22a is located on one side of the electrical contact portion 222 along the second direction.

[0060] In this invention, when multiple female terminals 22 are divided into first female terminals 22a and second female terminals 22b, and the piercing portion 221 of the first female terminal 22a is bent and connected to the contact portion 222, and the piercing portion 221 of the first female terminal 22a is located on one side of the contact portion 222 along the second direction, the piercing portion 221 of the first female terminal 22a and the piercing portion 221 of the second female terminal 22b can be arranged to avoid each other in the thickness direction of the piercing connector 100. When the thickness of the piercing portion 221 of the piercing connector 100 is less than its width, it is only necessary to bend the piercing portion 221 of the first female terminal 22a slightly in the thickness direction of the piercing connector 100 relative to the contact portion 222, so that the piercing portions 221 of the two adjacent female terminals 22 can avoid each other, thereby achieving the purpose of reducing the overall size of the piercing connector 100. Since the multiple female terminals 22 are arranged along the width direction of the piercing connector 100, multiple reductions in size can be made in the width direction of the piercing connector 100, while only one increase in size is needed in the thickness direction, thereby achieving a significant reduction in the size of the plug assembly 20. For example, when there are 10 female terminals 22, the 10 female terminals 22 are arranged sequentially along the width direction of the piercing connector 100. After the size between two adjacent female terminals 22 is reduced, nine reductions in size can be made in the width direction, while in the thickness direction, the avoidance between two adjacent female terminals 22 only results in one increase in size.

[0061] Optionally, the piercing portion 221 includes two piercing sub-portions 221a;

[0062] Each of the piercing sub-parts 221a is provided with a piercing groove 2211, which extends along the length direction of the piercing part 221. The piercing grooves 2211 of two piercing sub-parts 221a are arranged opposite to each other in a second direction. The piercing grooves 2211 are used for wire insertion. The piercing grooves 2211 of the plurality of female terminals 22 are spaced apart in a first direction.

[0063] The piercing groove 2211 has an insertion port for inserting a wire into the piercing groove 2211 on the side away from the power receiving part 222. The inner wall of the piercing groove 2211 is provided with a piercing blade, which is used to pierce the insulation layer of the wire.

[0064] In this invention, when each female terminal 22 is provided with two piercing sub-parts 221a, any one of the piercing sub-parts 221a of one of the two adjacent female terminals 22 can be stacked with the two piercing sub-parts 221a of the other female terminal 22, so that the arrangement of the multiple piercing sub-parts 221a between the two adjacent female terminals 22 is arranged in a toothed and staggered manner, which can ensure that the distance between the two adjacent electrical connection parts 222 can be reduced. The piercing groove 2211 has an insertion port on the side away from the power receiving part 222. The inner wall of the piercing groove 2211 can be sharpened to form a piercing blade. When the wire is inserted into the piercing groove 2211 through the insertion port, the piercing blade cuts through the outer sheath of the wire, exposing the internal conductive metal layer. When the wire is inserted into the piercing groove 2211, the exposed conductive metal layer inside the wire contacts the piercing part 221, thereby achieving an electrical connection between the wire and the female terminal 22. Furthermore, since the insertion port of the piercing groove 2211 is located on the side of the piercing groove 2211 away from the power receiving part 222, the wire can be simultaneously inserted into the piercing grooves 2211 of the two piercing sub-parts 221a from the insertion port of each piercing groove 2211, achieving a connection with the two piercing sub-parts 221a. Thus, by setting two piercing sub-parts 221a to improve the stability of the connection between the female terminal 22 and the wire, the piercing connection efficiency between the female terminal 22 and the wire can be improved.

[0065] In addition, the piercing grooves 2211 of the multiple female terminals 22 can be spaced apart along the width direction of the piercing connector 100. Even when adjacent piercing portions 221 are stacked, the adjacent piercing grooves 2211 will not overlap in the first direction (width direction of the piercing connector 100) due to the interval between them. When a wire is inserted into the piercing portion 221 along the second direction (thickness direction of the piercing connector 100), there will be no interference between adjacent wires, which would cause a short circuit between adjacent female terminals 22. In this way, the safety of the piercing connector 100 is ensured while minimizing the size of the piercing connector 100.

[0066] See Figure 3 , Figure 4 , Figure 10 As shown, in one embodiment, the auxiliary mounting member 30 is provided with a plurality of insertion portions 33 arranged along a first direction, the insertion portions 33 being used to insert and mount the piercing portion 221;

[0067] The plurality of insertion portions 33 include a plurality of first insertion slots 331 and a plurality of second insertion slots 332, wherein the first insertion slots 331 are used to insert the piercing portion 221 of the first female terminal 22a, and the second insertion slots 332 are used to insert the piercing portion 221 of the second female terminal 22b;

[0068] The first insertion slot 331 and the second insertion slot 332 extend along the insertion direction of the plug assembly 20. The arrangement of the multiple first insertion slots 331 and the multiple second insertion slots 332 can be set according to the arrangement of the first female terminal 22a piercing part 221 and the second female terminal 22b piercing part 221. In this way, each female terminal 22 can be fixed by the insertion slots preset on the auxiliary mounting member 30.

[0069] Multiple insertion slots 21a spaced apart along the first direction can be provided on the second housing 21. When the female terminal 22 is actually assembled, before the auxiliary mounting part 30 is assembled to the second housing 21, the power receiving part 222 of the female terminal 22 can be inserted into the insertion slot 21a. When the auxiliary mounting part 30 is installed to the second housing 21, the piercing part 221 of the female terminal 22 is inserted into its corresponding insertion slot from the end of the insertion part 33 near the socket assembly 10 along with the installation of the auxiliary mounting part 30. In this way, when the auxiliary mounting part 30 is installed to the second housing 21, the female terminal 22 is installed on the second housing 21.

[0070] When the female terminal 22 is inserted into the insertion slot, in order to prevent the female terminal 22 from exiting the insertion slot and causing the connection between the female terminal 22 and the second housing 21 to be unstable, the female terminal 22 may optionally include an anti-retraction tooth 223 provided on the piercing part 221. The anti-retraction tooth 223 is used to prevent the piercing part 221 from exiting the insertion part 33. The anti-retraction teeth 223 can be provided on each of the piercing sub-parts 221a of the female terminal 22, or on one of the piercing sub-parts 221a of the female terminal 22. Since the female terminal 22 is provided with anti-retraction teeth 223 at the piercing sub-parts 221, when the piercing sub-parts 221 are inserted into the insertion groove, the anti-retraction teeth 223 act on the inner wall of the insertion groove, so that the piercing sub-parts 221 cannot continue to move away from or towards the plug assembly 20 after insertion. This can prevent the contact part 222 of the female terminal 22 from loosening when it is connected to the male terminal 12, thereby making the female terminal 22 more securely installed on the second housing 21.

[0071] See Figure 2 , Figure 6 As shown, in one embodiment, the first insertion slot 331 includes a first sub-insertion slot 331a and a second sub-insertion slot 331b, and the first sub-insertion slot 331a and the second sub-insertion slot 331b are arranged at a relative interval along a second direction.

[0072] The second insertion slot 332 includes a third sub-insertion slot 332a and a fourth sub-insertion slot 332b, which are arranged at intervals relative to each other along the second direction.

[0073] The first sub-insertion slot 331a can be used to insert and install one of the piercing sub-parts 221a of the first female terminal 22a, the second sub-insertion slot 331b can be used to insert and install the other piercing sub-part 221a of the first female terminal 22a, the third sub-insertion slot 332a can be used to insert and install one of the piercing sub-parts 221a of the second female terminal 22b, and the fourth sub-insertion slot 332b can be used to insert and install the other piercing sub-part 221a of the second female terminal 22b. This allows the multiple piercing sub-parts 221a of each piercing part 221 to be limited and fixed by the auxiliary mounting member 30, thereby improving the fixing effect of the auxiliary mounting member 30 on the female terminal 22.

[0074] Furthermore, since the piercing portions 221 of adjacent female terminals 22 are stacked and spaced apart, and any piercing sub-part 221a of each adjacent piercing portion 221 is stacked and spaced apart from any piercing sub-part 221a of the adjacent piercing portion 221, in order to enable multiple sub-insertion slots to be inserted and engaged with their corresponding piercing sub-parts 221a respectively, adjacent sub-insertion slots can also be staggered. See [reference needed] Figure 6 As shown, optionally, the third sub-insertion slot 332a is located between the first sub-insertion slot 331a and the second sub-insertion slot 331b, and the second sub-insertion slot 331b is located between the third sub-insertion slot 332a and the fourth sub-insertion slot 332b.

[0075] Furthermore, the first sub-insertion slot 331a, the second sub-insertion slot 331b, and the third sub-insertion slot 332a are arranged at equal intervals along the second direction, and the second sub-insertion slot 331b, the third sub-insertion slot 332a, and the fourth sub-insertion slot 332b are arranged at equal intervals along the second direction.

[0076] In this way, the multiple sub-insertion slots opened on the auxiliary mounting member 30 can be evenly distributed. When multiple piercing sub-parts 221a are inserted into the corresponding sub-insertion slots, the auxiliary mounting member 30 applies a pre-tightening force along the thickness direction to the piercing sub-parts 221a through the inner wall of the sub-insertion slots. The pre-tightening force received by each piercing sub-part 221a is approximately equal. There will be no situation where some piercing sub-parts 221a receive too much pre-tightening force and some piercing sub-parts 221a receive too little pre-tightening force, resulting in the auxiliary mounting member 30 not being firmly fixed to the female terminal 22. Thus, through the above arrangement, the installation of the female terminal 22 on the second housing 21 can be made more secure. Similarly, the stress of the female terminal 22 acting on the second housing 21 can be made more uniform overall.

[0077] See Figure 4 , Figure 8As shown, in one embodiment, the first housing 11 has a slot 111, and the second housing 21 includes a plug-in portion 211 and a mounting portion 212. The plug-in portion 211 is used to plug into and install in the slot 111, and the mounting portion 212 is used to install the auxiliary mounting member 30.

[0078] Thus, by dividing the second housing 21 into a plug-in portion 211 and a mounting portion 212, the plug-in portion 211 and the mounting portion 212 can be respectively provided with different functions. A guide structure that cooperates with the plug-in portion 211 and the slot 111 can be provided so that after the plug-in portion 211 is guided into the slot 111 by the guide structure, the power receiving portion 222 of the female terminal 22 can be accurately connected with the male terminal 12. A corresponding mounting structure can be provided in the mounting portion 212 so that the auxiliary mounting component 30 can be more firmly fixed on the second housing 21, thereby making the female terminal 22 more firmly installed on the second housing 21.

[0079] See Figure 4 , Figure 6 , Figure 7 As shown, in one embodiment, the auxiliary mounting member 30 has a support groove 35, and there are multiple support grooves 35 located on both sides of the insertion part 33 along the second direction. The mounting part 212 has multiple support members 2121, and the multiple support members 2121 are inserted into the multiple support grooves 35 one by one to pre-tighten the piercing part 221 located in the insertion part 33.

[0080] This configuration ensures that the insertion part 33 has support grooves 35 on both sides of the piercing connector 100 in the thickness direction. Since each insertion part 33 includes two sub-insertion grooves spaced apart along the second direction, when the piercing part 221 (two piercing sub-parts 221a) of the female terminal 22 is inserted into the insertion part 33 (two sub-insertion grooves) and installed onto the second housing 21 along with the auxiliary mounting member 30, the support member 2121 on the second housing 21 can be inserted into the support groove 35, and the support member 2121 can press against the inner wall of the support groove 35. Because the insertion part 33 has support grooves 35 on both sides of the piercing connector 100 in the thickness direction... Support grooves 35 are provided on both sides of the connector. Therefore, the support grooves 35 on both sides will press the insertion part 33 towards the middle, so that the insertion part 33 can pre-tighten the piercing part 221 inserted therein along the second direction (the thickness direction of the piercing connector 100). This allows the female terminal 22 to achieve a tight connection with the auxiliary mounting part 30 in two directions through the cooperation of the anti-retraction tooth 223 with the insertion part 33 and the cooperation of the support member 2121 with the support groove 35. With the auxiliary mounting part 30 stably fixed to the second housing 21, the female terminal 22 can be installed more securely on the second housing 21.

[0081] Optionally, the auxiliary mounting component 30 includes a base 31 and two connecting portions 32. The two connecting portions 32 are respectively disposed on both sides of the base 31 along the second direction. The mounting portion 212 is engaged with each of the connecting portions 32 on both sides along the first direction. The mounting portion 212 is engaged with each of the connecting portions 32 on both sides along the second direction.

[0082] In this invention, the first direction can be the width direction of the piercing connector 100, and the second direction can be the width direction of the piercing connector 100. This allows both sides of the mounting portion 212 in the width direction and both sides in the thickness direction to be snapped and fixed with the connecting portion 32 of the auxiliary mounting member 30, so that the auxiliary mounting member 30 forms a circumferential fixation on the mounting portion 212. This makes the connection of the auxiliary mounting member 30 on the mounting portion 212 more secure. In addition, by engaging with the connecting portion 32, the installation efficiency of the auxiliary mounting member 30 can be improved when it is installed and fixed on the mounting portion 212, making the installation easier to operate.

[0083] The connection method between the auxiliary mounting component 30 and the mounting part 212 is further described below, such as... Figure 4 , Figure 5 , Figure 6 As shown, the mounting part 212 is provided with a plurality of first fasteners 2122 on both sides along the second direction, and each connecting part 32 is provided with a plurality of first fastening slots 321, and the plurality of first fasteners 2122 engage with the plurality of first fastening slots 321 one by one.

[0084] The first fastener 2122 can be a first protrusion, which engages with the first fastener groove 321 to achieve a snap-fit ​​between the first fastener 2122 and the first fastener groove 321. Since the overall width of the mounting part 212 along the thickness direction is relatively wide, multiple first fasteners 2122 are provided. When the auxiliary mounting part 30 is installed on the mounting part 212, there are more positions for the auxiliary mounting part 30 to engage with the mounting part 212 along the thickness direction, making the auxiliary mounting part 30 more secure when installed with the mounting part 212.

[0085] Furthermore, the mounting part 212 is provided with second latching grooves 2123 on both sides along the first direction, and the connecting part 32 is provided with second latching members 322 on both sides along the first direction, and the second latching members 322 engage with the second latching grooves 2123.

[0086] The second fastener 322 can be configured as a second protrusion, which engages with the second fastening groove 2123. Specifically, when the first fastener 2122 is engaged in the first fastening groove 321, the second fastener 322 engages in the second fastening groove 2123. This ensures that when the auxiliary mounting component 30 is installed in place through the engagement of the first fastener 2122 and the first fastening groove 321, the second fastener 322 of the auxiliary mounting component 30 engages in the second fastening grooves 2123 on both sides of the mounting portion 212 along the width direction, thus fixing the auxiliary mounting component 30 on both sides along the width direction.

[0087] Since there are two connecting parts 32, when setting the second fastener 322, the second fastener 322 can be set on both sides of each connecting part 32 along the width direction, so that the auxiliary mounting part 30 has two second fasteners 322 on both sides of the width direction. In this way, two second fastening grooves 2123 can be set on each side of the width direction of the mounting part 212, so that when the auxiliary mounting part 30 is installed on the mounting part 212, it can be fixed on both sides of the width direction by the four second fasteners 322. This makes the auxiliary mounting part 30 more firmly and stably installed on the mounting part 212.

[0088] See Figure 6 As shown, in one embodiment, the auxiliary mounting member 30 has a plurality of wiring slots 34 along the second direction, and the plurality of wiring slots 34 are connected to the plurality of insertion parts 33 one by one. The wiring slots 34 are used to insert the wires.

[0089] In this invention, since the piercing part 221 is inserted into the insertion part 33, the wire can be inserted into the insertion part 33 through the connector slot 34, thereby enabling the piercing part 221 to pierce the insulation layer of the wire.

[0090] The following section describes how the piercing part 221 pierces the insulation layer of the wire and how it connects to the wire. (See also...) Figure 5 , Figure 6 As shown, in one embodiment, the mounting portion 212 is further provided with a third latching groove 2124 on both sides along the first direction. The third latching groove 2124 engages with the second latching member 322. The third latching groove 2124 is located on the side of the second latching groove 2123 away from the insertion portion 211.

[0091] The second fastener 322 has a first position that engages with the third fastening groove 2124, and a second position that engages with the second fastening groove 2123;

[0092] When the second latching member 322 is in the first position, the terminal slot 34 is used to insert a wire. When the second latching member 322 is in the first position, the piercing part 221 is used to pierce the insulation layer of the wire to electrically connect the wire.

[0093] In the above embodiment, since the third latching groove 2124 is located on the side of the second latching groove 2123 away from the insertion part 211, and the third latching groove 2124 engages with the second latching member 322, when the second latching member 322 is in the first position, the auxiliary mounting member 30 is not installed in place on the mounting part 212. At this time, the free end of the wire can be inserted into the connector slot 34. When the auxiliary mounting member 30 moves toward the second housing 21, the second latching member 322 is disengaged from the third latching groove. When 2124 moves toward the second latching groove 2123, the piercing part 221 of the female terminal 22 is inserted into the insertion part 33 and moves toward the position where the insertion part 33 communicates with the terminal slot 34, piercing the insulation layer of the wire located in the terminal slot 34 and connecting with the conductive layer of the wire. When the second latching member 322 moves to engage with the second latching groove 2123, the first latching member 2122 engages in the first latching groove 321, and the auxiliary mounting member 30 is installed in place on the second housing 21.

[0094] Thus, by setting the third latching groove 2124 to engage with the second latching member 322, the auxiliary mounting member 30 can be pre-positioned on the second housing 21, thereby facilitating the insertion of the wire into the terminal slot 34.

[0095] When installing the auxiliary mounting component 30 to the second housing 21, a guide component can also be provided to guide the movement of the auxiliary mounting component 30, such as... Figure 4 , Figure 6 As shown, optionally, the mounting portion 212 has first guide grooves 2125 on both sides along the first direction. The first guide grooves 2125 extend from the mounting portion 212 towards the insertion portion 211. The connecting portion 32 has guide strips 323 on both sides along the first direction that slide in cooperation with the first guide grooves 2125. Thus, when the auxiliary mounting component 30 is installed on the mounting portion 212, the sliding cooperation between the guide strips 323 and the first guide grooves 2125 allows the auxiliary mounting component 30 to move precisely on the mounting portion 212. This facilitates the movement of the second latching component 322 from the position engaging with the third latching groove 2124 to the position engaging with the second latching groove 2123, ensuring that the auxiliary mounting component 30 is accurately assembled on the mounting portion 212.

[0096] Alternatively, the second snap-fit ​​groove 2123 and the third snap-fit ​​groove 2124 can be disposed on the inner wall of the first guide groove 2125, and the second snap-fit ​​member 322 can be disposed on the guide strip 323, so that there is no need to set an additional position on the auxiliary mounting member 30 for arranging the second snap-fit ​​member 322, and there is no need to set an additional position on the mounting part 212 for arranging the second snap-fit ​​groove 2123 and the third snap-fit ​​groove 2124.

[0097] Furthermore, the groove wall of each of the aforementioned sub-slots 34 can be arranged in an inner arc shape, and the free end of the support member 2121 can be arranged in an inner arc shape. This allows the inner wall of the sub-slot 34 and the end of the support member 2121 to adapt to the shape of the wire. When the piercing part 221 pierces and connects the wire, the inner wall of the sub-slot 34 and the end of the support member 2121 can secure the wire by bundling it.

[0098] Alternatively, multiple terminal slots 34 can be sequentially connected to form a terminal slot, and reserved slots 341 are provided at both ends of the terminal slot along the first direction. In this way, when the piercing part 221 squeezes the wire to perform a piercing operation, the outer insulation of the wire can move toward the part connected to the adjacent terminal slot 34 and toward the reserved slot 341, preventing the wire from being squeezed, deformed, and bursting the terminal slot 34.

[0099] When the plug assembly 20 is inserted into the slot 111 of the socket assembly 10, to improve the stability of the connection between the two, such as Figure 4 , Figure 8 As shown, optionally, the second housing 21 further includes two sets of latching parts 213. The two sets of latching parts 213 are respectively disposed on both sides of the insertion part 211 along the first direction. One latching part 213 engages with the inner wall of the slot 111 on one side along the first direction, and the other latching part 213 engages with the inner wall of the slot 111 on the other side along the first direction.

[0100] With this configuration, after the second housing 21 is inserted into the slot 111, both sides of the second housing 21 along the width direction are engaged with the first housing 11, thereby making the insertion and installation of the plug assembly 20 on the socket assembly 10 more secure and preventing the plug assembly 20 from becoming loose after being installed on the socket assembly 10.

[0101] The structure of the latching part 213 will be further described below. (See attached document.) Figure 4As shown, optionally, the latching part 213 includes a rib 2131 and a third latching protrusion 2132. The rib 2131 is elastically connected to the insertion part 211. The rib 2131 has a third latching protrusion 2132 on the side opposite to the insertion part 211. The inner wall of the slot 111 has a latching opening 113 that engages with the third latching protrusion 2132. A deformation space is provided between the rib 2131 and the insertion part 211. The rib 2131 is used to move toward the deformation space under the action of external force so that the third latching protrusion 2132 engages and separates from the latching opening 113.

[0102] The rib 2131 extends from the insertion part 211 to the mounting part 212. The deformation space can extend from one side of the insertion part 211 to one side of the mounting part 212. The third latching protrusion 2132 can be set on a section of the rib 2131 near the insertion part 211. When the ribs 2131 of the two latching parts 213 are pressed towards the corresponding deformation spaces at the same time, the third latching protrusion 2132 of each latching part 213 can move towards the deformation space along with the rib 2131, thereby narrowing the overall width of the second housing 21. When the width of the part of the second housing 21 used for insertion into the slot 111 is smaller than the insertion space... When the inner diameter of the slot 111 is wide enough, the third latching protrusion 2132 can separate from the corresponding latch 113, thereby allowing the second housing 21 to separate from the first housing 11. Since the rib 2131 is elastically connected to the insertion part 211, when the rib 2131 is not subjected to the squeezing force towards the deformation space, the rib 2131 can return to a position away from the deformation space. When the second housing 21 is inserted into the slot 111, the third latching protrusion 2132 can move towards the latch 113 and engage with the latch 113, so that the second housing 21 is engaged in the slot 111, thereby realizing the connection and fixation of the plug assembly 20 and the socket assembly 10.

[0103] Additionally, the latching part 213 may also include a pressing part 2133. The other end of the rib 2131 is elastically connected to the mounting part 212. The pressing part 2133 is located on the side of the rib 2131 away from the mounting part 212. The pressing part 2133 is used to drive the rib 2131 toward the deformation space under the action of external force. The pressing part 2133 may be inclined. The portion of the pressing part 2133 near the third latching protrusion 2132 protrudes more from the second housing 21 than the portion of the pressing part 2133 away from the third latching protrusion 2132. This facilitates the movement of the rib 2131 toward the deformation space by pressing the protruding portion of the pressing part 2133, making it easier for the third latching protrusion 2132 to separate from the latch 113, thereby making it easier for the plug assembly 20 to separate from the socket assembly 10 under the action of external force.

[0104] Optionally, the plug-in portion 211 is provided with a guide rib 2111, the guide rib 2111 extends from one side of the plug-in portion 211 near the mounting portion 212 to the other side, and the inner wall of the slot 111 is provided with a second guide groove 1112 that slides with the guide rib 2111.

[0105] With this configuration, when the plug assembly 20 and the socket assembly 10 are plugged in and installed, the second guide groove 1112 and the guide rib 2111 can guide the second housing 21 to move precisely within the slot 111, thereby facilitating the precise connection of the female terminal 22's contact portion 222 with the male terminal 12 and achieving power connection. In actual installation of the above-mentioned guide structure, the portion of the rib 2131 with the third latching protrusion 2132 can cooperate with the side of the plug-in portion 211 to serve as a set of guide ribs 2111. Another set of guide ribs 2111 can be provided at the position of the plug-in portion 211 between two ribs 2131, allowing the plug assembly 20 to be guided at multiple points during installation.

[0106] Additionally, when mounting the socket assembly 10 onto the circuit board 200, a reinforcing member 112 may be provided to enhance the mounting stability of the socket assembly 10 on the circuit board 200. Optionally, the piercing connector 100 may further include the circuit board 200, with the first housing 11 connected to the circuit board 200.

[0107] The first housing 11 has reinforcing members 112 on both sides along the first direction, and the reinforcing members 112 are connected to the circuit board 200.

[0108] In the above embodiment, mounting grooves 115 can be provided on both sides of the first housing 11 along the first direction. A reinforcing member 112 can be fitted into the mounting groove 115. The reinforcing member 112 can be a metal reinforcing plate, and one end of the reinforcing member 112 connected to the circuit board 200 can be welded and fixed to the circuit board 200. Thus, while strengthening the overall structural strength of the first housing 11 through the reinforcing member 112, the connection between the first housing 11 and the circuit board 200 can also be made more secure, making it less likely for the socket assembly 10 to loosen when the plug assembly 20 is inserted or removed. Additionally, a solder clearance groove can be formed on the side of the first housing 11 facing the circuit board 200. When the socket assembly 10 is connected to the circuit board 200 by solder, it can prevent excessive solder from lifting the first housing 11, thus preventing a loose connection between the socket assembly 10 and the circuit board 200.

[0109] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
