[0050] In the field of modern automobile manufacturing, the fast and accurate installation of connectors plays a vital role in improving the efficiency of vehicle assembly and ensuring the reliability of circuits. To achieve this goal, many automotive connectors integrate sophisticated guidance and positioning features to ensure accurate docking during assembly. However, although the connectors in the prior art have made significant progress in installation convenience, there is still room for further optimization in miniaturization design.

[0051] The present invention provides a piercing connector which has an overall flat structure and is applied to the wiring connection of a car headlight power supply. By reducing the volume of the piercing connector, the space occupied by the piercing connector for wiring is reduced.

[0052] See also 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, wherein the socket assembly 10 includes a first housing 11 and a plurality of male terminals 12 disposed in the first housing 11, wherein the plurality of male terminals 12 are arranged at intervals along a first direction; the plug assembly 20 includes a second housing 21 and a plurality of female terminals 22 disposed in the second housing 21, wherein the second housing 21 is plugged with the first housing 11, and each of the female terminals 22 includes a piercing portion 221 and a power connection portion 222, wherein the plurality of female terminals 22 are arranged at intervals along a first direction; The power connection portion 222 is mated with the multiple male terminals 12 one by one, and the piercing portions 221 of adjacent female terminals 22 are stacked and spaced apart, each of the piercing portions 221 includes at least two piercing sub-portions 221a, and the at least two piercing portions 221 are spaced apart along the second direction, and each of the piercing portions 221 is used to connect the wire through the at least two piercing sub-portions 221a, wherein the first direction and the second direction are cross-arranged; the auxiliary mounting member 30 is provided on the second shell 21, and is used to fix the multiple female terminals 22 to the second shell 21.

[0053] In the present invention, the first direction may be the width direction of the piercing connector 100, and the second direction may be the thickness direction of the piercing connector 100. The piercing connector 100 may also include a circuit board 200, the first housing 11 may be fixed to the circuit board 200, and the plurality of male terminals 12 provided on the first housing 11 may be connected to the power connection end of the circuit board 200, the plurality of male terminals 12 and the plurality of female terminals 22 may be matched one by one, and a clamping portion may be provided at one end of the power connection portion 222 of the female terminal 22 close to the male terminal 12, and when the second housing 21 is plugged and installed in the first housing 11, the clamping portion of each female terminal 22 clamps the corresponding male terminal 12, so that the plug assembly 20 and the socket assembly 10 are electrically connected. Among them, the plurality of male terminals 12 may be arranged at intervals along the width direction of the socket assembly 10, so that the socket assembly 10 is flat, and the plurality of female terminals 22 may be arranged at intervals along the width direction of the plug assembly 20, so that the plug assembly 20 is flat, so that the piercing connector 100 is generally flat.

[0054] like Figure 2 , Figure 8 As shown, when the first housing 11 is installed on the circuit board 200, a plurality of positioning posts 114 may be provided at the bottom of the first housing 11, and positioning holes plugged with the positioning posts 114 may be provided on the circuit board 200, so that the first housing 11 can be accurately positioned at the installation position specified by 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 installed on the first housing 11, an insertion groove 1111 may be provided at one end of the first housing 11 away from the second housing 21, and the male terminal 12 is inserted from the insertion groove 1111 into the slot 111 of the first housing 11.

[0055] Among them, the plurality of male terminals 12 are arranged at intervals along the width direction of the piercing connector 100, which means that there is a gap between adjacent male terminals 12 to prevent electrical connection between adjacent male terminals 12. Since the electrical connection portion 222 of the female terminal 22 is connected to the male terminal 12, the electrical connection portions 222 of the plurality of female terminals 22 can also be arranged at intervals along the width direction of the piercing connector 100. In this way, while ensuring that there is a gap between two adjacent male terminals 12 and that they will not short-circuit, the distance between two adjacent male terminals 12 can be reduced to reduce the overall width of the plurality of male terminals 12 after installation, thereby achieving the purpose of reducing the width dimension of the socket assembly 10.

[0056] When the distance between two adjacent male terminals 12 is reduced, the distance between the power connection parts 222 of two adjacent female terminals 22 will be reduced. Since the piercing part 221 of the female terminal 22 is used to pierce the insulation layer of the wire and to connect the internal metal layer of the wire for electrical connection, the width of the piercing part 221 of the female terminal 22 should be greater than the width of the power connection part 222. When the distance between the power connection parts 222 of two adjacent female terminals 22 is reduced, in order to prevent the piercing parts 221 of the adjacent female terminals 22 from interfering with each other, the piercing parts 221 of the two adjacent female terminals 22 can be arranged at intervals in a stacked manner. For example, the piercing parts 221 of the two adjacent female terminals 22 are overlapped 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 the two, it can be ensured that the adjacent female terminals 22 will not be short-circuited. In this way, the overall size of the multiple female terminals 22 after being installed and arranged in the second housing 21 can be reduced, thereby reducing the width of the plug assembly 20. Without reducing the overall number of electrical terminals of the piercing connector 100, the overall size of the piercing connector 100 can be reduced. When the female terminal 22 pierces the bonding layer of the wire through the piercing portion 221 to make an electrical connection with the wire, in order to improve the stability of the connection between the piercing portion 221 and the wire, the piercing portion 221 can have at least two piercing sub-portions 221a, and the at least two piercing sub-portions 221a are arranged at intervals along the thickness direction of the piercing connector 100. By making a single piercing portion 221 have multiple piercing sub-portions 221a, a single female terminal 22 can pierce multiple positions of the wire through the multiple piercing sub-portions 221a, so that the single female terminal 22 is connected and fixed to the wire at multiple positions, thereby ensuring the stability of the connection between the female terminal 22 and the wire.

[0057] The technical solution of the present invention is to arrange multiple male terminals 12 at intervals along the first direction, to make each female terminal 22 have a piercing portion 221 and a power connection portion 222, and to make multiple power connection portions 222 match multiple male terminals 12 one by one, so that multiple female terminals 22 are arranged at intervals along the first direction at the positions of the power connection portions 222. When the piercing portion 221 is wider than the power connection portion 222, adjacent piercing portions 221 are arranged at intervals in a stacked manner, so that the piercing portions 221 of two adjacent female terminals 22 can be closer, thereby making the two adjacent female terminals 22 closer. When the distance between each two adjacent female terminals 22 is reduced, the arrangement width of the multiple female terminals 22 on the second housing 21 can be reduced, thereby reducing The width dimension of the plug assembly 20 is reduced because the arrangement width of the multiple female terminals 22 on the second shell 21 is reduced, and the spacing between the multiple male terminals 12 that are connected to the multiple female terminals 22 one by one is also reduced, thereby reducing the width dimension of the socket assembly 10. Therefore, the piercing connector 100 can be smaller in size by arranging adjacent female terminals 22 more closely. In addition, by making a single piercing portion 221 have at least two piercing sub-portions 221a spaced along the second direction, a single female terminal 22 can be pierced and connected to the wire through at least two piercing sub-portions 221a, thereby making the connection between the female terminal 22 and the wire more stable. In the field of automotive connectors, it is beneficial to assemble and use the piercing connector 100 in a narrow space.

[0058] See also Fig.10 , Fig.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, and each of the first female terminals 22a is disposed adjacent to the second female terminal 22b;

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

[0060] In the present invention, when a plurality of female terminals 22 are divided into a first female terminal 22a and a second female terminal 22b, and the piercing portion 221 of the first female terminal 22a is bent and connected to the power connection portion 222, and the piercing portion 221 of the first female terminal 22a is located on one side of the power connection 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 smaller than its width, the piercing portion 221 of the first female terminal 22a only needs to be bent slightly toward the thickness direction of the piercing connector 100 relative to the power connection portion 222, so that the piercing portions 221 of 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, the size can be reduced multiple times in the width direction of the piercing connector 100, and the size only needs to be increased once in the thickness direction, thereby achieving the purpose of significantly reducing the size of the plug assembly 20. For example, when there are 10 female terminals 22, the 10 female terminals 22 are arranged in sequence along the width direction of the piercing connector 100. After the size between two adjacent female terminals 22 is reduced, the size can be reduced 9 times in the width direction, and in the thickness direction, the avoidance of two adjacent female terminals 22 will only result in one increase in size.

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

[0062] Each of the piercing sub-portions 221a is provided with a piercing groove 2211, and the piercing groove 2211 is extended along the length direction of the piercing portion 221, and the piercing grooves 2211 of the two piercing sub-portions 221a are arranged opposite to each other along the second direction, and the piercing grooves 2211 are used for wire insertion, and the piercing grooves 2211 of the plurality of female terminals 22 are arranged at intervals along the first direction;

[0063] An insertion port for inserting a wire into the piercing groove 2211 is provided on one side of the piercing groove 2211 away from the power connection portion 222 , and a piercing blade is provided on the inner side wall of the piercing groove 2211 , and the piercing blade is used to pierce the insulation layer of the wire.

[0064] In the present invention, when each female terminal 22 is provided with two piercing sub-portions 221a, any one piercing sub-portion 221a of one of the two adjacent female terminals 22 can be stacked with the two piercing sub-portions 221a of the other female terminal 22, respectively, so that the multiple piercing sub-portions 221a of the two adjacent female terminals 22 are arranged in a tooth-shaped and staggered arrangement, thereby ensuring that the distance between the two adjacent power connection portions 222 can be reduced. Among them, an insertion port is provided on the side of the puncture groove 2211 away from the power connection part 222, and the inner side wall of the puncture groove 2211 can be set in a sharp shape to form a puncture blade. When the wire is inserted into the puncture groove 2211 from the insertion port of the puncture groove 2211, the puncture blade scratches the outer skin of the wire to expose its internal metal conductive layer. When the wire is inserted into the puncture groove 2211, the exposed metal conductive layer in the wire contacts the puncture part 221, so that the wire and the female terminal 22 are electrically connected. In addition, since the insertion port of the puncture groove 2211 is located on the side of the puncture groove 2211 away from the power connection part 222, the wire can be inserted into the puncture groove 2211 of the two puncture sub-parts 221a from the insertion port of each puncture groove 2211 at the same time to achieve connection with the two puncture sub-parts 221a. In this way, while providing two puncture sub-parts 221a to improve the connection stability between the female terminal 22 and the wire, the puncture connection efficiency between the female terminal 22 and the wire can be improved.

[0065] In addition, the piercing grooves 2211 of the plurality of female terminals 22 can be arranged at intervals along the width direction of the piercing connector 100. Even when adjacent piercing portions 221 are arranged in a stacked manner, due to the presence of intervals between adjacent piercing grooves 2211, adjacent piercing grooves 2211 will not be stacked in the first direction (the width direction of the piercing connector 100). When a wire is inserted into the piercing portion 221 along the second direction (the thickness direction of the piercing connector 100), interference between adjacent wires will not occur, which would cause a short circuit between adjacent female terminals 22. In this way, the safety of electrical connection of the piercing connector 100 can be ensured while minimizing the volume of the piercing connector 100.

[0066] See also Figure 3 , Figure 4 , Fig.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, and the insertion portions 33 are used for inserting and mounting 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] Among them, the first insertion groove 331 and the second insertion groove 332 are extended along the insertion direction of the plug assembly 20, and the arrangement of multiple first insertion grooves 331 and multiple second insertion grooves 332 can be arranged according to the arrangement of the piercing portion 221 of the first female terminal 22a and the piercing portion 221 of the second female terminal 22b. In this way, each female terminal 22 can be fixed by the insertion groove preset on the auxiliary mounting part 30.

[0069] A plurality of insertion grooves 21a spaced apart along the first direction may be provided on the second shell 21. When the female terminal 22 is actually assembled, before the auxiliary mounting member 30 is assembled to the second shell 21, the power connection portion 222 of the female terminal 22 may be inserted into the insertion groove 21a. When the auxiliary mounting member 30 is installed to the second shell 21, the piercing portion 221 of the female terminal 22 is inserted into the corresponding insertion groove from the end of the insertion portion 33 close to the socket assembly 10 along with the installation of the auxiliary mounting member 30. In this way, when the auxiliary mounting member 30 is installed to the second shell 21, the female terminal 22 is installed on the second shell 21.

[0070] When the female terminal 22 is inserted and installed in the insertion slot, in order to prevent the female terminal 22 from withdrawing from the insertion slot, resulting in an unstable connection between the female terminal 22 and the second shell 21, optionally, the female terminal 22 also includes an anti-backout tooth 223 provided on the piercing portion 221, and the anti-backout tooth 223 is used to prevent the piercing portion 221 from withdrawing from the insertion portion 33. Among them, the anti-retraction tooth 223 can be set on each piercing sub-portion 221a of the female terminal 22, and can also be set on one of the piercing sub-portions 221a of the female terminal 22. Since the female terminal 22 is provided with the anti-retraction tooth 223 at the piercing portion 221, when the piercing portion 221 is inserted into the insertion slot, the anti-retraction tooth 223 acts on the inner wall of the insertion slot, so that the piercing portion 221 cannot continue to move away from or close to the plug assembly 20 after insertion. In this way, the power connection portion 222 of the female terminal 22 can be prevented from loosening when docking with the male terminal 12, thereby making the female terminal 22 more firmly installed on the second shell 21.

[0071] See also 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 relatively spaced apart along the second direction;

[0072] The second insertion groove 332 includes a third sub-insertion groove 332a and a fourth sub-insertion groove 332b, and the third sub-insertion groove 332a and the fourth sub-insertion groove 332b are arranged relatively spaced apart along the second direction.

[0073] Among them, the first sub-insertion groove 331a can be used to insert and install one of the piercing sub-portions 221a of the first female terminal 22a, the second sub-insertion groove 331b can be used to insert and install another piercing sub-portion 221a of the first female terminal 22a, the third sub-insertion groove 332a can be used to insert and install one of the piercing sub-portions 221a of the second female terminal 22b, and the fourth sub-insertion groove 332b can be used to insert and install another piercing sub-portion 221a of the second female terminal 22b, so that the multiple piercing sub-portions 221a of each piercing portion 221 can be limited and fixed by the auxiliary mounting member 30, so that the auxiliary mounting member 30 has a better fixing effect on the female terminal 22.

[0074] In addition, since the piercing portions 221 of adjacent female terminals 22 are arranged in a stacked and spaced arrangement, and any piercing sub-portion 221a of each adjacent piercing portion 221 is stacked and spaced with any piercing sub-portion 221a of the adjacent piercing portion 221, in order to enable the plurality of sub-insertion slots to be respectively plugged with the corresponding piercing sub-portions 221a, the adjacent sub-insertion slots can also be arranged in a staggered manner, see 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] In addition, further, 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 grooves opened on the auxiliary mounting part 30 can be evenly spaced and distributed. When the multiple piercing sub-portions 221a are inserted and installed in the corresponding sub-insertion grooves, the auxiliary mounting part 30 applies the pre-tightening force to the piercing sub-portion 221a along the thickness direction through the inner wall of the sub-insertion groove. The pre-tightening force applied to each piercing sub-portion 221a is substantially equal, and there will be no situation where the pre-tightening force applied to some piercing sub-portions 221a is too large and the pre-tightening force applied to some piercing sub-portions 221a is too small, resulting in the auxiliary mounting part 30 not firmly fixing the female terminal 22. Therefore, the above-mentioned arrangement can make the installation of the female terminal 22 on the second shell 21 more secure. Similarly, the stress applied by the female terminal 22 on the second shell 21 can be made more uniform as a whole.

[0077] See also Figure 4 , Figure 8As shown, in one embodiment, the first shell 11 is provided with a slot 111 , and the second shell 21 includes a plug-in portion 211 and a mounting portion 212 , the plug-in portion 211 is used for plugging and mounting in the slot 111 , and the mounting portion 212 is used for mounting the auxiliary mounting member 30 .

[0078] In this way, by dividing the second shell 21 into the plug-in portion 211 and the mounting portion 212, the plug-in portion 211 and the mounting portion 212 can be respectively provided with different functions, and guiding structures that cooperate with each other can be provided on the plug-in portion 211 and the slot 111, so that after the plug-in portion 211 is inserted into the slot 111 through the guidance of the guiding structure, the power connection portion 222 of the female terminal 22 can be accurately docked with the male terminal 12, and a corresponding mounting structure can be provided on the mounting portion 212, so that the auxiliary mounting part 30 can be fixed more firmly on the second shell 21, thereby making the female terminal 22 more firmly installed on the second shell 21.

[0079] See also Figure 4 , Figure 6 , Figure 7 As shown, in one embodiment, the auxiliary mounting member 30 is provided with a support groove 35, and a plurality of the support grooves 35 are provided and respectively located on both sides of the insertion portion 33 along the second direction, and the mounting portion 212 is provided with a plurality of support members 2121, and the plurality of support members 2121 are plugged into and matched with the plurality of support grooves 35 one by one to pre-tighten the puncture portion 221 located in the insertion portion 33.

[0080] In this way, the insertion portion 33 is provided with support grooves 35 on both sides of the piercing connector 100 in the thickness direction. Since each insertion portion 33 includes two sub-insertion grooves spaced apart along the second direction, when the piercing portion 221 (two piercing sub-portions 221a) of the female terminal 22 is plugged into the insertion portion 33 (two sub-insertion grooves) and installed to 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 squeeze the inner wall of the support groove 35. Since the insertion portion 33 is provided with support grooves 35 on both sides of the piercing connector 100 in the thickness direction, the female terminal 22 can be inserted into the support groove 35. Support grooves 35 are provided on both sides, so the support grooves 35 on both sides will squeeze the insertion part 33 toward 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), so that the female terminal 22 can be fastened to the auxiliary mounting part 30 in two directions through the cooperation between the anti-retraction teeth 223 and the insertion part 33, and the cooperation between the support part 2121 and the support grooves 35. When the auxiliary mounting part 30 is stably fixed to the second shell 21, the female terminal 22 can be installed more firmly on the second shell 21.

[0081] Optionally, the auxiliary mounting member 30 includes a base 31 and two connecting parts 32, and the two connecting parts 32 are respectively arranged on both sides of the base 31 along the second direction, and the two sides of the mounting part 212 along the first direction are respectively snap-fitted with each of the connecting parts 32, and the two sides of the mounting part 212 along the second direction are respectively snap-fitted with each of the connecting parts 32.

[0082] In the present 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, so that both sides of the width direction and both sides of the thickness direction of the mounting portion 212 can be snap-fitted and fixed with the connecting portion 32 of the auxiliary mounting member 30, so that the auxiliary mounting member 30 is fixed on the mounting portion 212 in a surrounding manner, thereby making the connection of the auxiliary mounting member 30 on the mounting portion 212 more secure. In addition, by snapping and cooperating with the connecting portion 32, when the auxiliary mounting member 30 is installed and fixed on the mounting portion 212, the installation efficiency of the auxiliary mounting member 30 can be improved, making the installation easier to operate.

[0083] The connection method between the auxiliary mounting member 30 and the mounting portion 212 is further described below. Figure 4 , Figure 5 , Figure 6 As shown, the mounting portion 212 is provided with a plurality of first buckle members 2122 on both sides along the second direction, each of the connecting portions 32 is provided with a plurality of first buckle grooves 321, and the plurality of first buckle members 2122 are engaged with the plurality of first buckle grooves 321 one by one.

[0084] Among them, the first fastener 2122 can be a first fastening protrusion, which is inserted into the first fastening groove 321 through the first fastening protrusion to achieve the snap-fitting cooperation between the first fastener 2122 and the first fastening groove 321. Since the overall width of the mounting part 212 on both sides along the thickness direction is wider, multiple first fasteners 2122 are arranged for this purpose. When the auxiliary mounting part 30 is installed to the mounting part 212, there are more positions where the auxiliary mounting part 30 is snap-fitted and installed with the mounting part 212 on both sides along the thickness direction, so that the auxiliary mounting part 30 is more firmly installed with the mounting part 212.

[0085] Furthermore, the mounting portion 212 is provided with second snap grooves 2123 on both sides along the first direction, and the connecting portion 32 is provided with second snap members 322 on both sides along the first direction, and the second snap members 322 are snap-fitted with the second snap grooves 2123 .

[0086] The second snap member 322 can be set as a second snap projection, and the second snap member 322 is snapped and matched with the second snap groove 2123, and the second snap member 322 can be snapped into the second snap groove 2123 when the first snap member 2122 is snapped into the first snap groove 321. In this way, when the auxiliary mounting member 30 is installed in place through the cooperation between the first snap member 2122 and the first snap groove 321, the second snap member 322 of the auxiliary mounting member 30 is snapped into the second snap grooves 2123 on both sides of the mounting portion 212 along the width direction, so that both sides of the auxiliary mounting member 30 along the width direction are fixed.

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

[0088] See also Figure 6 As shown, in one embodiment, the auxiliary mounting member 30 is provided with a plurality of wiring sub-grooves 34 along the second direction, and the plurality of wiring sub-grooves 34 are connected to the plurality of insertion portions 33 one by one, and the wiring sub-grooves 34 are used to insert the wires.

[0089] In the present invention, since the piercing portion 221 is inserted into the insertion portion 33 , the wire can be inserted into the insertion portion 33 through the terminal slot 34 , so that the piercing portion 221 can pierce the insulation layer of the wire.

[0090] The following is an introduction to how the piercing portion 221 pierces the insulation layer of the wire and how it is connected to the wire. Figure 5 , Figure 6 As shown, in one embodiment, the mounting portion 212 is further provided with third snap grooves 2124 on both sides along the first direction, the third snap grooves 2124 are snap-fitted with the second snap member 322, and the third snap grooves 2124 are provided on a side of the second snap groove 2123 away from the plug-in portion 211;

[0091] The second locking member 322 has a first position for locking in the third locking groove 2124 and a second position for locking in the second locking groove 2123;

[0092] When the second latch 322 is in the first position, the wiring slot 34 is used to insert the wire. When the second latch 322 is in the first position, the piercing portion 221 is used to pierce the insulation layer of the wire to electrically connect the wire.

[0093] In the above embodiment, since the third snap groove 2124 is arranged on the side of the second snap groove 2123 away from the plug-in portion 211, and the third snap groove 2124 is snap-fitted with the second snap member 322, when the second snap member 322 is in the first position, the auxiliary mounting member 30 is not installed in place on the mounting portion 212, and the free end of the wire can be inserted into the wiring sub-slot 34 at this time, when the auxiliary mounting member 30 moves toward the second housing 21, the second snap member 322 is moved from the third snap groove When 2124 moves toward the second snap groove 2123, the piercing portion 221 of the female terminal 22 is inserted from the insertion portion 33 and moves toward the position where the insertion portion 33 is connected to the terminal slot 34, piercing the insulating layer of the wire in the terminal slot 34 and connecting with the conductive layer of the wire. When the second snap member 322 moves to snap into the second snap groove 2123, the first snap member 2122 is snapped into the first snap groove 321, and the auxiliary mounting member 30 is installed in place on the second shell 21.

[0094] In this way, by providing the third snap groove 2124 and engaging with the second snap 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 the auxiliary mounting member 30 is mounted to the second housing 21, a guide member may be provided to guide the movement of the auxiliary mounting member 30. Figure 4 , Figure 6 As shown, optionally, the mounting portion 212 is provided with first guide grooves 2125 on both sides along the first direction, the first guide grooves 2125 are extended from the mounting portion 212 toward the plug-in portion 211, and the connecting portion 32 is provided with guide bars 323 slidably matched with the first guide grooves 2125 on both sides along the first direction. In this way, when the auxiliary mounting member 30 is mounted on the mounting portion 212, the auxiliary mounting member 30 can be accurately moved on the mounting portion 212 through the sliding match between the guide bars 323 and the first guide grooves 2125, so that the second snap member 322 is convenient to move from the position snapped with the third snap groove 2124 to the position snapped with the second snap groove 2123, so that the auxiliary mounting member 30 can be accurately assembled on the mounting portion 212.

[0096] In addition, the second snap groove 2123 and the third snap groove 2124 can be arranged on the inner wall of the first guide groove 2125, and the second snap component 322 can be arranged 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 component 322, and there is no need to set an additional position on the mounting part 212 for arranging the second snap groove 2123 and the third snap groove 2124.

[0097] Furthermore, the groove wall of each of the wiring sub-grooves 34 can be set in an inner arc shape, and the free end of the support member 2121 can be set in an inner arc shape, so that the inner wall of the wiring sub-groove 34 and the end of the support member 2121 can adapt to the shape of the wire. When the piercing portion 221 pierces and connects the wire, the inner wall of the wiring sub-groove 34 and the end of the support member 2121 can bundle and fix the wire.

[0098] In addition, a plurality of the wiring sub-grooves 34 may be connected in sequence to form a wiring groove, and reserved grooves 341 are provided at both ends of the wiring groove along the first direction. In this way, when the piercing portion 221 squeezes the wire to perform the piercing operation, the outer insulation of the wire may move toward the portion where the adjacent wiring sub-grooves 34 are connected, and toward the reserved grooves 341, to prevent the wire from being squeezed, deformed, and bursting the wiring sub-grooves 34.

[0099] When the plug assembly 20 is plugged into the slot 111 of the socket assembly 10, in order to improve the stability of the connection between the two, as shown in FIG. Figure 4 , Figure 8 As shown, optionally, the second shell 21 also includes two groups of snap-fit ​​portions 213, and the two groups of snap-fit ​​portions 213 are respectively arranged on both sides of the plug-in portion 211 along the first direction, one of the snap-fit ​​portions 213 is snap-fitted with the inner wall of one side of the slot 111 along the first direction, and the other snap-fit ​​portion 213 is snap-fitted with the inner wall of the other side of the slot 111 along the first direction.

[0100] With such a configuration, after the second shell 21 is inserted and installed in the slot 111, both sides of the second shell 21 along the width direction are snap-fitted with the first shell 11, thereby making the plug assembly 20 more securely inserted and installed on the socket assembly 10, and preventing the plug assembly 20 from loosening after being installed on the socket assembly 10.

[0101] The structure of the buckle portion 213 is further described below. Figure 4As shown, optionally, the buckle portion 213 includes a rib 2131 and a third latching protrusion 2132, the rib 2131 is elastically connected to the plug-in portion 211, the third latching protrusion 2132 is provided on the side of the rib 2131 facing away from the plug-in portion 211, the inner wall of the slot 111 is provided with a bayonet 113 which is snap-fitted with the third latching protrusion 2132, a deformation space is provided between the rib 2131 and the plug-in portion 211, and the rib 2131 is used to move toward the deformation space under the action of external force so that the third latching protrusion 2132 is snap-fitted and separated from the bayonet 113.

[0102] The rib 2131 extends from the plug-in portion 211 to the mounting portion 212, and the deformation space can extend from one side of the plug-in portion 211 to one side of the mounting portion 212. The third clamping protrusion 2132 can be arranged at a section of the rib 2131 close to the plug-in portion 211. When the ribs 2131 of the two buckle portions 213 are pressed toward the corresponding deformation space at the same time, the third clamping protrusion 2132 of each buckle portion 213 can move toward the deformation space along with the rib 2131, thereby narrowing the overall width of the second shell 21. When the width of the portion of the second shell 21 used for plugging into the slot 111 is smaller than the width of the plug-in portion 111, the third clamping protrusion 2132 can be arranged at a section of the rib 2131 close to the plug-in portion 211. When the inner diameter width of the groove 111 is large, the third latching protrusion 2132 can be separated from the corresponding bayonet 113, so that the second shell 21 can be separated from the first shell 11; because the rib 2131 is elastically connected to the plug-in portion 211, when the rib 2131 is not subjected to the extrusion force toward the deformation space, the rib 2131 can be reset to a position away from the deformation space; when the second shell 21 is inserted into the slot 111, the third latching protrusion 2132 can move toward the bayonet 113 and be engaged with the bayonet 113, so that the second shell 21 is engaged in the slot 111, thereby realizing the connection and fixation between the plug assembly 20 and the socket assembly 10.

[0103] In addition, the buckle portion 213 may also include a pressing portion 2133, the other end of the rib 2131 is elastically connected to the mounting portion 212, the pressing portion 2133 is arranged on the side of the rib 2131 away from the mounting portion 212, and the pressing portion 2133 is used to drive the rib 2131 to move toward the deformation space under the action of an external force. The pressing portion 2133 may be arranged in an inclined manner, and the portion of the pressing portion 2133 close to the third clamping protrusion 2132 is more protruding from the second shell 21 than the portion of the pressing portion 2133 away from the third clamping protrusion 2132, so that the rib 2131 can be moved toward the deformation space as a whole by pressing the protruding portion of the pressing portion 2133, so that the third clamping protrusion 2132 is more easily separated from the bayonet 113, thereby making it easier for the plug assembly 20 to be separated from the socket assembly 10 under the action of an external force.

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

[0105] With such a configuration, when the plug assembly 20 is plugged and installed with the socket assembly 10, the second housing 21 can be accurately moved in the slot 111 through the guiding cooperation of the second guide groove 1112 and the guide rib 2111, so as to facilitate the precise docking of the power connection portion 222 of the female terminal 22 with the male terminal 12 to achieve power connection. When the above-mentioned guide structure is actually configured, the portion of the rib 2131 provided with the third protrusion 2132 can be matched with the side of the plug-in portion 211 to form a group of guide ribs 2111, and another group of guide ribs 2111 can be provided at the position of the plug-in portion 211 between the two ribs 2131, so that the plug assembly 20 can be guided through multiple positions when installed.

[0106] In addition, when the socket assembly 10 is installed on the circuit board 200, a reinforcing member 112 may be provided to enhance the installation firmness of the socket assembly 10 on the circuit board 200. Optionally, the piercing connector 100 further includes a circuit board 200, and the first housing 11 is connected to the circuit board 200;

[0107] Reinforcements 112 are disposed on both sides of the first housing 11 along a first direction, and the reinforcements 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 shell 11 along the first direction, and the reinforcement member 112 can be embedded and installed in the mounting grooves 115. The reinforcement member 112 can be provided as a metal reinforcement plate, and one end of the reinforcement member 112 connected to the circuit board 200 can be welded and fixed to the circuit board 200. In this way, while the overall structural strength of the first shell 11 is strengthened by the reinforcement member 112, the connection and fixation between the first shell 11 and the circuit board 200 can be made more firmly, so that when the plug assembly 20 is plugged in and out, the socket assembly 10 is not easy to loosen. In addition, a circle of solder avoidance grooves can be provided on the side of the first shell 11 facing the circuit board 200. When the socket assembly 10 is connected to the circuit board 200 by soldering, it can prevent the first shell 11 from being lifted up by excessive solder, resulting in a loose connection between the socket assembly 10 and the circuit board 200.
