Description

Technical Field

[0001] The utility model relates to a hybrid connector, in particular to a hybrid connector with a terminal locking member.

Background Art

[0002] There is a prior hybrid connector applied to an automobile, such as the hybrid connector in Chinese Patent CN202123416956.4. It includes a housing and a first terminal and a second terminal fixed in the housing. The size of the second terminal is larger than that of the first terminal. A locking member is fixed in the housing and has a pre-locking position and a final-locking position. A plurality of avoidance grooves and a plurality of blocking surfaces are alternately distributed in the left-right direction on the cantilever portion of the locking member, and a plurality of the blocking surfaces are in the same plane in the front-back direction. When the locking member is in the pre-locking position, the avoidance grooves are aligned and communicated with the terminal grooves in the housing, so that the first terminal and the second terminal can pass through the avoidance grooves and extend into the terminal grooves. When the locking member moves to the final-locking position, a plurality of the blocking surfaces respectively move to the rear of the first locking surface of the first terminal and the second locking surface of the second terminal to block the first terminal and the second terminal from withdrawing backward from the housing.

[0003] However, since it is necessary to ensure that the first terminal and the second terminal are inserted into the housing from the rear to the front, a plurality of the avoidance grooves are provided on the cantilever portion for the first terminal and the second terminal to pass through. Since the cantilever portion is slender in the left-right direction, setting a plurality of the avoidance grooves on the cantilever portion further weakens the thickness of the cantilever portion, which will make the strength of the cantilever portion become weak. As a result, the locking member is likely to break during demolding after injection molding or during the process of being installed in the housing, and then the first terminal and the second terminal cannot be stably positioned in the housing. Moreover, since a plurality of the blocking surfaces are located in the same plane in the front-rear direction, when a plurality of the blocking surfaces stop behind the first locking surface and the second locking surface, it is necessary to ensure that the first locking surface of the main body portion of the first terminal and the second locking surface of the main body portion of the second terminal are flush with each other in the front-rear direction. In this way, it is necessary to extend the size of the main body portion of the first terminal to ensure that the first locking surface and the second locking surface are flush, which will additionally increase the length of the first terminal and increase the cost. In addition, the locking member needs to pass through two positions, namely pre-locking and final locking, to fix the first terminal and the second terminal, so that the installation process of the locking member becomes complicated. Moreover, if there is a slight deviation in the position of the avoidance groove and the terminal groove when the locking member is in the pre-locked state, the first terminal and the second terminal cannot be smoothly inserted into the housing, making the assembly of the first terminal and the second terminal difficult.

[0004] Therefore, it is necessary to design a hybrid connector to solve the above technical problems.

[0034] As Figures 1 to 11 shown, the hybrid connector 1000 of the present utility model is defined with a front-back direction, and the front-back direction is the docking direction of the hybrid connector 1000 with a pair of docking connectors (not shown, the same below), and a left-right direction and an up-down direction perpendicular to the front-back direction. For the convenience of understanding the drawings, the forward direction in the front-back direction is the positive direction of the X-axis, the rightward direction in the left-right direction is the positive direction of the Y-axis, and the upward direction in the up-down direction is the positive direction of the Z-axis.

[0035] As Figures 1 to 11As shown in the figure, the hybrid connector 1000 of the present utility model includes an insulating body 1, a plurality of first terminals 2 and a plurality of second terminals 3 fixed to the insulating body 1, and a terminal locking member 4 inserted into the insulating body 1 from one side in the left-right direction to position the plurality of first terminals 2 and the plurality of second terminals 3.

A plurality of connecting portions 13 are arranged at intervals in the up-down direction and connect the front portion 11 and the rear portion 12 into one body. The plurality of connecting portions 13 can not only be used to guide the plurality of second terminals 3 to be inserted into the front portion 11 from the rear to the front, but also be used to block the plurality of second terminals 3 from shifting toward the side away from the first terminals 2. In other words, the connecting portions 13 can block the second terminals 3 from shifting outward. The front surface of the front portion 11 is a docking interface 111 for docking with the docking connector. The docking interface 111 in the area where the first terminals 2 are located and the docking interface 111 in the area where the second terminals 3 are located are in the same plane in the front-rear direction.

[0037] As Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 9 As shown in the figure, the insulating body 1 is provided with a plurality of first receiving grooves 14 and a plurality of second receiving grooves 15 penetrating in the front-rear direction. In other words, the plurality of first receiving grooves 14 and the plurality of second receiving grooves 15 penetrate the front portion 11 and the rear portion 12 in the front-rear direction, that is, each first receiving groove 14 and each second receiving groove 15 extend forward from the rear side of the rear portion 12 and penetrate the front portion 11 forward. The plurality of first receiving grooves 14 are arranged in at least two rows in the left-right direction. In this embodiment, the plurality of first receiving grooves 14 are arranged in four rows in the left-right direction (of course, in other embodiments, the first receiving grooves 14 can be arranged in two rows, three rows, five rows or multiple rows, etc.). The plurality of second receiving grooves 15 are arranged in a row in the up-down direction and are located on one side of the plurality of first receiving grooves 14 in the left-right direction. Specifically, the second receiving grooves 15 arranged in a row in the up-down direction are located on the left side of the multiple rows of first receiving grooves 14.

The limiting groove 17 communicates with a row of the second receiving grooves 15 in the up-down direction, and the limiting groove 17 communicates with four rows of the first receiving grooves 14 in the left-right direction. In this embodiment, the limiting groove 17 communicates with all of the first receiving grooves 14 in the two rows of the first receiving grooves 14 located on the upper and lower outer sides among the four rows of the first receiving grooves 14, while the limiting groove 17 communicates with most of the receiving grooves in the two rows of the first receiving grooves 14 located on the inner side among the four rows of the first receiving grooves 14 (of course, in other embodiments, it may also be that the limiting groove 17 communicates with all of the first receiving grooves 14 in the four rows of the first receiving grooves 14). A waterproof ring 8 is further installed on the insulating body 1. The waterproof ring 8 is located behind the limiting groove 17 and is installed on the outer side of the rear part 12.

[0039] As Figure 1 , Figure 4 and Figure 9 shown, a plurality of the first terminals 2 are arranged in four rows in the left-right direction (of course, in other embodiments, a plurality of the first terminals 2 may also be arranged in two rows, three rows or multiple rows, etc. in the left-right direction). The plurality of the first terminals 2 are respectively received in the plurality of the first receiving grooves 14. Among the four rows of the first terminals 2, the two adjacent rows of the first terminals 2 located on the upper side form a terminal group Q, and the two adjacent rows of the first terminals 2 located on the lower side also form a terminal group Q. Along the up-down direction, the two rows of the first terminals 2 in each terminal group Q are arranged in a staggered manner in the up-down direction, and when viewed in the left-right direction, the projections of the two rows of the first terminals 2 in the same terminal group Q are symmetrically arranged in the up-down direction. The distance between two adjacent rows of the first terminals 2 in the same terminal group Q along the up-down direction is less than the distance between two adjacent rows of the first terminals 2 in different terminal groups Q.

Each first terminal 2 has a first main body portion 21, a first intermediate portion 22 located behind the first main body portion 21, and a first wire pressing portion 23 located behind the first main body portion 21 and the first intermediate portion 22. The first terminal 22 also has a first contact portion 24. The first contact portion 24 is located inside the first main body portion 21, and the first main body portion 21 and the first contact portion 24 are integrally formed (of course, in other embodiments, the first main body portion 21 and the first contact portion 24 can also be integrally formed). Specifically, the first contact portion 24 is integrally formed with the first intermediate portion 22 and the first wire pressing portion 23, and the front and rear ends of the first intermediate portion 22 are respectively connected to the first contact portion 24 and the first wire pressing portion 23. The first main body portion 21 is separately formed, and the first main body portion 21 is fixed and covers the outside of the first contact portion 24. The first main body portion 21 includes a plug-in box 211 and a locking box 212 integrally connected to the plug-in box 211 and stacked on the plug-in box 211 in the up and down direction. The rear end of the locking box 212 forms the first locking surface 2121. The terminal locking member 4 abuts against the rear of the first locking surface 2121 to limit the backward displacement of the first terminal 2. The front end of the first wire pressing portion 23 is connected to the rear end of the first intermediate portion 22. The first wire pressing portion 23 has a first opening 231. A cable 7 extends into the first wire pressing portion 23 from the first opening 231, and the first wire pressing portion 23 is used for crimping the cable 7. The first openings 231 of two adjacent rows of the first terminals 2 in the same terminal group Q are arranged to face away from each other in the up and down direction.

[0041] As Figure 1 , Figure 4 , Figure 5 and Figure 9 shown, the second terminal 3 is a power terminal, and the number of the second terminals 3 is three. The three second terminals 3 are arranged in a row in the up and down direction (of course, in other embodiments, the number of the second terminals 3 can also be two, four or more, etc. Multiple second terminals 3 can also be arranged in two rows, three rows or multiple rows in the up and down direction). Multiple second terminals 3 are respectively received in multiple second terminal slots. Among them, the two second terminals 3 located on the upper and lower sides respectively overlap at least partially with two rows of the first terminals 2 in two terminal groups Q in the left and right directions. The second terminal 3 located in the middle is located between the two terminal groups Q in the up and down direction, and the second terminal 3 located in the middle is misaligned with multiple first terminals 2 when viewed in the left and right direction.

[0042] As Figure 1 , Figure 4 , Figure 5 andFigure 9 As shown, each of the second terminals 3 has a second main body portion 31, a second intermediate portion 32 located behind the second main body portion 31, and a second wire pressing portion 33 located behind the second intermediate portion 32. Each of the second terminals 3 further has a second contact portion 34, the second contact portion 34 is integrally formed separately from the second main body portion 31 (of course, in other embodiments, the second contact portion 34 may also be integrally formed with the second main body portion 31), and the second contact portion 34 is located inside the second main body portion 31. Specifically, the second contact portion 34 is integrally formed with the second intermediate portion 32 and the second wire pressing portion 33, and the front and rear ends of the second intermediate portion 32 are respectively connected to the second contact portion 34 and the second wire pressing portion 33. The second main body portion 31 is formed separately, and the second main body portion 31 is fixed and covers the outside of the second contact portion 34.

[0043] As Figure 1 , Figure 4 , Figure 5 and Figure 9As shown, the height of the second main body portion 31 in the up-down direction is less than the width of the second main body portion 31 in the left-right direction. The rear surface of the first main body portion 21 is located in front of the rear surface of the second main body portion 31. Looking in the left-right direction, the second main body portion 31 of one of the second terminals 3 overlaps with the first main body portions 21 of two rows of the first terminals 2, and the two outer side surfaces of the two first main body portions 21 that are away from each other respectively extend beyond the upper and lower surfaces of the corresponding second main body portion 31 in the up-down direction. Specifically, looking in the left-right direction, the second main body portions 31 of the two second terminals 3 on the upper and lower sides respectively overlap with the first main body portions 21 of two rows of the first terminals 2 in the two terminal groups Q, and the two outer side surfaces of the adjacent two rows of the first main body portions 21 in the same terminal group Q that are away from each other respectively extend beyond the upper and lower surfaces of the corresponding second main body portion 31 in the up-down direction. The height of each second main body portion 31 in the up-down direction is greater than the height of each first main body portion 21 in the up-down direction. The overall length of the second main body portion 31 in the front-rear direction is longer than the overall length of the first main body portion 21, and in the front-rear direction, a part of the second main body portion 31 is located in the limiting groove 17, and another part is located in the second receiving groove 15 at the front part, and the first main body portion is located in the first receiving groove 14 at the front part; thus, there is a sufficient safe insertion and extraction distance when the docking terminal (not shown, the same below) of the docking connector is inserted into the inside of the second main body portion 31 to dock with the second contact portion 34. The second main body portion 31 includes a connection box 311 and two clamping arms 312 integrally extending forward from the upper and lower surfaces of the connection box 311. A second locking surface 3111 is formed at the rear end of the connection box 311. The second contact portion 34 is located between the two clamping arms 312 and is formed separately from the two clamping arms 312 (of course, in other embodiments, the second contact portion 34 and the clamping arms 312 may also be integrally formed). The connection box 311 of the second main body portion 31 respectively has a positioning elastic piece 3112 in the up-down direction, and the positioning elastic piece 3112 is used to position the second main body portion 31 at the front part 11. The second wire pressing portion 33 has a second opening 331, and the wire 7 extends into the second wire pressing portion 33 from the second opening 331, and the second wire pressing portion 33 is used to press the wire 7. The second opening 331 is opened in the left-right direction, and the opening direction of the second opening 331 is perpendicular to the opening direction of the first opening 231.

[0044] As Figures 1 to 10As shown, the terminal locking member 4 is inserted and fixed into the limiting groove 17 in the left-right direction at one time. Specifically, after the first terminal 2 and the second terminal 3 are inserted into the insulating body 1 from back to front, the terminal locking member 4 is inserted into the limiting groove 17 at one time, and at the same time, the first terminal 2 and the second terminal 3 are blocked and limited. The terminal locking member 4 has a base portion 41 and at least two crossbars 42 extending in the left-right direction from the base portion 41 and spaced apart in the up-down direction. In this embodiment, the number of the crossbars 42 is four (of course, in other embodiments, the number of the crossbars 42 can be two, three, etc.). The front surface of the crossbar 42 is used to block the backward displacement of the first main body portion 21.

[0045] As Figure 1 , Figure 4 , Figure 10 and Figure 11 shown, each crossbar 42 has a blocking portion 421 connecting the base portion 41 and extending in the left-right direction. A main strengthening portion 422 extends backward from the rear end of the blocking portion 421, and one side of the main strengthening portion 422 is connected to the base portion 41. In the up-down direction, the thickness of the blocking portion 421 is greater than the thickness of the main strengthening portion 422. In the front-rear direction, the width of the main strengthening portion 422 is greater than the width of the blocking portion 421. The front surface of the blocking portion 421 is used to block the first main body portion 21. In the up-down direction, the main strengthening portions 422 of the two adjacent upper crossbars 42 are farther from the second main body portion 31 of the second terminal 3 on the upper side than the blocking portion 421. Similarly, in the up-down direction, the main strengthening portions 422 of the two adjacent lower crossbars 42 are farther from the second main body portion 31 of the second terminal 3 on the lower side than the blocking portion 421. In this way, the main strengthening portion 422 provides a clearance for the positioning elastic piece 3112 of the corresponding second terminal 3.

[0046] As Figure 1 , Figure 4 , Figure 10 and Figure 11As shown, on the side of each main reinforcement part 422 away from the base part 41, a secondary reinforcement part 423 is connected. The front end of the secondary reinforcement part 423 is connected to the blocking part 421. In the up and down direction, the thickness of the secondary reinforcement part 423 is smaller than that of the main reinforcement part 422. In the up and down direction, the first pressing line part 23 and the main reinforcement part 422 are offset from each other. And in the up and down direction, the secondary reinforcement parts 423 of two adjacent crossbars 42 are farther away from the first pressing line part 23 than the main reinforcement part 422. Specifically, in the up and down direction, the secondary reinforcement parts 423 of two adjacent upper crossbars 42 are farther away from the first pressing line part 23 of the two rows of the first terminals 2 in the upper terminal group Q. Similarly, in the up and down direction, the secondary reinforcement parts 423 of two adjacent lower crossbars 42 are farther away from the first pressing line part 23 of the two rows of the first terminals 2 in the lower terminal group Q, so that the secondary reinforcement part 423 provides a space for the corresponding first pressing line part 23. In the left and right direction, the lengths of the two outermost crossbars 42 are greater than those of the inner crossbars 42. And in the up and down direction, the thicknesses of the two outermost crossbars 42 are greater than those of the inner crossbars 42. In the up and down direction, each of the two outermost crossbars 42 is provided with a groove 424 and a buckle arm 425 outside the groove 424 in the up and down direction. And in the up and down direction, the groove 424 and the corresponding buckle arm 425 are arranged opposite to each other and provide an elastic deformation space for the buckle arm 425, so that the terminal locking part 4 can be inserted into the limiting groove 17 and be buckled with the insulating body 1. Moreover, the width of the main reinforcement part 422 of the inner crossbar 42 in the front and back direction is greater than the width of the main reinforcement part 422 of the two outermost crossbars 42.

[0047] As Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 9As shown, the base 41 is provided with a plurality of communication grooves 43 corresponding to the plurality of connection portions 13. Each connection portion 13 correspondingly enters each communication groove 43 to stop the displacement of the base 41 in the up and down direction in the up and down direction. Moreover, the inner wall surfaces of the plurality of connection portions 13 can also be used to stop the offset of the plurality of second main body portions 31 toward one side of the base 41. One side of the base 41 close to the cross bar 42 is recessed with a plurality of limiting grooves 44 from front to back. The plurality of limiting grooves 44 are spaced apart in the up and down direction. Two adjacent limiting grooves 44 are respectively located on the upper and lower sides of the communication groove 43 and communicate with the communication groove 43. Two corners on the side of the second main body portion 31 away from the first main body portion 21 in the left and right direction respectively enter two adjacent limiting grooves 44. And two wall surfaces of the two adjacent limiting grooves 44 that are relatively parallel in the up and down direction are used to limit the displacement of the second main body portion 31 in the up and down direction. Two wall surfaces on the same side of the two adjacent limiting grooves 44 in the left and right direction are substantially aligned with the inner wall surface of the connection portion 13 in the up and down direction to limit the offset of the second main body portion 31 toward one side of the base 41. One side of the base 41 close to the cross bar 42 is provided with a plurality of stop surfaces 45 in the left and right direction. The rear end surface of the limiting groove 44 is the stop surface 45. Each stop surface 45 is further back than the front surface of the cross bar 42. The plurality of stop surfaces 45 are used to stop the plurality of second main body portions 31 from moving backward.

[0048] As Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 9 and Figure 10As shown, when the terminal locking member 4 is inserted into the limit groove 17 in the left-right direction, two adjacent crossbars 42 respectively cross over the upper and lower sides of at least one second main body portion 31, and the front surfaces of the two crossbars 42 respectively stop behind two rows of the first main body portions 21. Specifically, two adjacent crossbars 42 located on the upper side respectively cross over the upper and lower side surfaces of the second main body portion 31 of the upper second terminal 3, and there are gaps between the second main body portion 31 and the two crossbars 42 located on its upper and lower sides. Moreover, the front surfaces of the blocking portions 421 of the two adjacent crossbars 42 located on the upper side respectively stop behind two rows of the first main body portions 21 of the upper terminal group Q. In this embodiment, among the two crossbars 42 located on the upper side, the longer crossbar 42 in the left-right direction stops behind all the first main body portions 21 of the first terminal 2 located in the uppermost row, and the shorter crossbar 42 stops behind most of the first main body portions 21 of the corresponding row of the first terminals 2, that is, the first main body portion 21 of the rightmost first terminal 2 in this row of the first terminals 2 is not blocked by the crossbar 42 (of course, in other embodiments, it may also be that the two crossbars 42 located on the upper side both stop behind all the first main body portions 21 of their corresponding rows of the first terminals 2, that is, the first main body portions 21 of the two rows of the first terminals 2 in the upper terminal group Q are respectively blocked by the two crossbars 42 located on the upper side); similarly, two adjacent crossbars 42 located on the lower side respectively cross over the upper and lower side surfaces of the second main body portion 31 of the lower second terminal 3, and there are gaps between the second main body portion 31 and the two crossbars 42 located on its upper and lower sides. Moreover, the front surfaces of the blocking portions 421 of the two adjacent crossbars 42 located on the lower side respectively stop behind two rows of the first main body portions 21 of the lower terminal group Q. In this embodiment, among the two crossbars 42 located on the lower side, the longer crossbar 42 in the left-right direction stops behind all the first main body portions 21 of the first terminal 2 located in the lowermost row, and the shorter crossbar 42 stops behind most of the first main body portions 21 of the corresponding row of the first terminals 2, that is, the first main body portion 21 of the rightmost first terminal 2 in this row of the first terminals 2 is not blocked by the crossbar 42 (of course, in other embodiments, it may also be that the two crossbars 42 located on the lower side both stop behind all the first main body portions 21 of their corresponding rows of the first terminals 2, that is, the first main body portions 21 of the two rows of the first terminals 2 in the lower terminal group Q are respectively blocked by the two crossbars 42 located on the lower side).In the same terminal group Q, the upper part of the rear end of the first main body 21 of the upper row of the two adjacent rows of the first terminals 2 is the first locking surface 2121. The first locking surface 2121 extends upward beyond the upper surface of the corresponding second main body 31 and is blocked by one of the crossbars 42. The lower part of the rear end of the first main body 21 of the lower row of the first terminals 2 is the first locking surface 2121. The first locking surface 2121 extends downward beyond the lower surface of the corresponding second main body 31 and is blocked by the other crossbar 42.

[0049] As Figure 1 and Figure 9 shown, the insulating body 1 is also provided with a plurality of third receiving grooves 16 penetrating in the front-rear direction, that is, the plurality of third receiving grooves 16 penetrate through the front part 11 and the rear part 12 in the front-rear direction. The plurality of third receiving grooves 16 are arranged at intervals in the up-down direction, and two adjacent third receiving grooves 16 are offset from each other in the up-down direction. In the left-right direction, the plurality of third receiving grooves 16 are located on the other side of the plurality of first receiving grooves 14. Specifically, the plurality of third receiving grooves 16 are located on the right side of the plurality of rows of first receiving grooves 14. The insulating body 1 is further recessed with a clamping groove 18. The clamping groove 18 is disposed opposite to the limiting groove 17 in the left-right direction, and the clamping groove 18 communicates with the plurality of third receiving grooves 16. In this embodiment, the clamping groove 18 also communicates with the rightmost one of the first receiving grooves 14 in the two inner rows of the first receiving grooves 14 respectively (of course, in other embodiments, the clamping groove 18 may also be only connected to the third receiving grooves 16 and not connected to the first receiving grooves 14).

[0050] As Figure 1 、 Figure 3 and Figure 9 shown, a plurality of third terminals 5 are respectively received in the plurality of third receiving grooves 16. The third terminals 5 are power terminals. In this embodiment, the number of the third terminals 5 is also three (of course, in other embodiments, the number of the second terminals 3 may also be two, four, etc.). The three third terminals 5 are arranged at intervals in the up-down direction, and the two third terminals 5 located on the upper and lower sides are arranged in a row in the up-down direction. The third terminal 5 located inside is offset from the third terminals 5 on the upper and lower sides. In the left-right direction, the plurality of second terminals 3 and the plurality of third terminals 5 are respectively located on the left and right sides of the plurality of first terminals 2.

[0051] As Figure 1 、 Figure 2 and Figure 3As shown, each of the third terminals 5 has a third main body portion 51, a third intermediate portion 52 located at the rear end of the third main body portion 51, and a third wire pressing portion 53 located at the rear end of the third intermediate portion 52. The height of the third main body portion 51 in the up and down direction is greater than the height of the second main body portion 31. The third wire pressing portion 53 has a third opening 531. The cable 7 extends into the third wire pressing portion 53 from the third opening 531, and the third wire pressing portion 53 is used for crimping the cable 7. The opening direction of the first opening 231 is perpendicular to the opening directions of the third opening 531 and the second opening 331.

[0052] As Figure 1 , Figure 2 and Figure 3 shown, a stopper 6 is inserted into the clamping groove 18, and the stopper 6 is used for stopping the backward displacement of the plurality of third terminals 5. The stopper 6 has a side portion 61 and two partitions 62 extending in the left and right direction from the side portion 61 toward the side of the terminal locking member 4 and spaced apart in the up and down direction. The partitions 62 separate the plurality of third terminals 5 in the up and down direction. In the up and down direction, the two partitions 62 partially overlap with the two outermost crossbars 42. In the left and right direction, the two partitions 62 are respectively disposed opposite to the two inner crossbars 42. And the free end of each partition 62 stops behind a first main body portion 21 (certainly, in other embodiments, the free terminal of each partition 62 can stop behind two, three or more first main body portions 21, or the partition 62 is disposed out of alignment with the first main body portion 21, that is, the partition 62 does not stop behind the first main body portion 21, and the first main body portions 21 are all stopped and positioned by the terminal locking member 4).

[0053] In summary, the hybrid connector 1000 of the present utility model has the following beneficial effects:

[0054] (1) A plurality of the first terminals 2 are respectively received in a plurality of the first receiving grooves 14, and a plurality of the second terminals 3 are respectively received in a plurality of the first receiving grooves 15. The terminal locking member 4 is inserted and fixed into the limiting groove 17 in the left-right direction at one time to limit the first terminal 2 and the second terminal 3. In this way, not only does the assembly process of the terminal locking member 4 become simple, without the need for pre-locking and final-locking secondary assembly, but also since the first terminal 2 and the second terminal 3 are first inserted into the insulating body 1 and the terminal locking member 4 is inserted into the insulating body 1 later, the installation of the first terminal 2 and the second terminal 3 is convenient. The terminal locking member 4 has the base portion 41 and a plurality of crossbars 42 extending from the base portion 41 in the left-right direction and spaced apart in the up-down direction. Adjacent two crossbars 42 respectively cross over the upper and lower sides of one second main body portion 31, and the front surfaces of the two crossbars 42 respectively abut against the rear of two rows of the first main body portions 21. On the side of the base portion 41 close to the crossbars 42 in the left-right direction, a plurality of stop surfaces 45 are provided. Each stop surface 45 is further back than the front surface of the crossbar 42. The plurality of stop surfaces 45 are used to stop the plurality of second main body portions 31 from moving backward. In this way, there is no need to provide avoidance grooves on the crossbars 42 for the first main body portion 21 and the second main body portion 31 to pass through, which makes the crossbars 42 have better strength, avoids the crossbars 42 from breaking, and ensures that the crossbars 42 can stably stop the first main body portion 21 for a long time. Further, since the front surface of the crossbar 42 is located in front of the stop surface 45, there is no need to increase the length of the first main body portion 21, thereby reducing the manufacturing cost.

[0055] (2) The insulating body 1 has a front portion 11 located in front of the limiting groove 17 and a rear portion 12 located behind the limiting groove 17. A plurality of the connecting portions 13 are arranged at intervals in the up and down direction and connect the front portion 11 and the rear portion 12 into one body; in this way, the insulating body 1 can be integrally injection-molded. Compared with the insulating body 1 being a split type, the number of molds used in molding is reduced, the manufacturing cost of the insulating body 1 is reduced, and compared with the need for assembly when the insulating body 1 is a split type, the integral insulating body 1 has good precision. The plurality of connecting portions 13 are used to block the offset of the plurality of second main body portions 31 toward one side of the base portion 41. The base portion 41 is provided with a plurality of communication grooves 43 corresponding to the plurality of connecting portions 13. Each connecting portion 13 correspondingly enters each communication groove 43 to block the displacement of the base portion 41 in the up and down direction; in this way, the connecting portion 13 can not only guide the second main body portion 31 to be smoothly inserted into the front portion 11 from back to front without skew, but also limit the up and down position of the terminal locking member 4, thereby ensuring that the terminal locking member 4 can stably block the backward displacement of the first main body portion 21 and the second main body portion 31.

[0056] (3) Along the left and right direction, two corners on the side of the second main body portion 31 away from the first main body portion 21 respectively enter two adjacent limiting grooves 44, and two wall surfaces of the two limiting grooves 44 that are relatively parallel in the up and down direction are used to limit the displacement of the second main body portion 31 in the up and down direction. The rear end surface of the limiting groove 44 forms a stopping surface 45 to block the backward displacement of one side of the second main body portion 31. The inner wall surfaces of the plurality of connecting portions 13 are used to block the offset of the plurality of second main body portions 31 toward one side of the base portion 41; in this way, by providing two limiting grooves 44, the up and down displacement of the second main body portion 31 can be limited, and the inner wall surfaces of the connecting portions 13 can block the second main body portion 31 in the left and right direction. This can prevent the second terminal 3 from rotating along the axis extending in the front and rear direction of the second terminal 3 in the second receiving groove 15, and the setting of the stopping surface 45 can prevent the second terminal 3 from withdrawing backward from the second receiving groove 15, so that the second main body portion 31 can be stably positioned in the insulating body 1.

[0057] (4) The crossbar 42 has the blocking portion 421 that connects to the base portion 41 and extends in the left - right direction. The main strengthening portion 422 extends backward from the rear end of the blocking portion 421, and one side of the main strengthening portion 422 is connected to the base portion 41. In the up - down direction, the thickness of the blocking portion 421 is greater than the thickness of the main strengthening portion 422. In the front - rear direction, the width of the main strengthening portion 422 is greater than the width of the blocking portion 421. The front surface of the blocking portion 421 is used to block the first main body portion 21. The connection box 311 of the second main body portion 31 respectively has the positioning elastic pieces 3112 in the up - down direction. In the up - down direction, the main strengthening portions 422 of two adjacent crossbars 42 are farther from the second main body portion 31 than the blocking portions 421, so that the main strengthening portions 422 provide a clearance for the positioning elastic pieces 3112. Thus, the relatively thick thickness of the blocking portion 421 can not only increase the strength of the crossbar 42, thereby reducing the risk of the crossbar 42 breaking, but also ensure that the blocking portion 421 can block the rear of the first main body portion 21, thereby preventing the first main body portion 21 from moving backward. And the setting of the main strengthening portion 422 can avoid the situation that the positioning elastic piece 3112 interferes with the main strengthening portion 422 and damages the second terminal 3.

[0058] (5) The secondary strengthening portion 423 is connected to the side of the main strengthening portion 422 away from the base portion 41. The front end of the secondary strengthening portion 423 is connected to the blocking portion 421. In the up - down direction, the thickness of the secondary strengthening portion 423 is less than the thickness of the main strengthening portion 422. The first terminal 2 has the first wire - pressing portion 23 located behind the first main body portion 21. In the up - down direction, the first wire - pressing portion 23 and the main strengthening portion 422 are mutually misaligned. In the up - down direction, the secondary strengthening portions 423 of two adjacent crossbars 42 are farther from the first wire - pressing portion 23 than the main strengthening portions 422, so that the secondary strengthening portions 423 provide a clearance for the first wire - pressing portion 23, avoiding interference between the first wire - pressing portion 23 and the secondary strengthening portion 423 of the terminal locking member 4. And the thicknesses of the blocking portion 421, the main strengthening portion 422 and the secondary strengthening portion 423 are inconsistent. While ensuring to meet the installation requirements of the first terminal 2 and the second terminal 3, the terminal locking member 4 is made to have relatively strong strength as much as possible.

[0059] (6) The thicknesses of the two outermost crossbars 42 in the up-and-down direction are greater than the thickness of the crossbar 42 at the middle position. The two outermost crossbars 42 in the up-and-down direction are both provided with the grooves 424 and the buckle arms 425 outside the grooves 424 in the up-and-down direction. The grooves 424 and the corresponding buckle arms 425 are arranged opposite to each other in the up-and-down direction. In this way, the grooves 424 can provide a deformation space for the corresponding buckle arms 425 in the up-and-down direction, which is more convenient for the terminal locking member 4 to be inserted into the limiting groove 17 and be latched with the insulating body 1. Setting the crossbars 42 on the upper and lower sides to be longer and thicker can not only ensure that the crossbars 42 can block the first main body parts 21 of the two rows of the first terminals 2 on the upper and lower sides, but also ensure that the crossbars 42 on the upper and lower sides have better strength. The width of the main strengthening part 422 of the crossbar 42 located inside in the front-and-back direction is greater than the width of the main strengthening part 422 of the two outermost crossbars 42. In this way, all the crossbars 42 located inside can have sufficient strength, thereby avoiding the crossbars 42 from breaking due to being too slender and long.

[0060] The above detailed description is only for the description of the preferred embodiments of the present invention, and does not limit the patent scope of the present invention. Therefore, all equivalent technical changes made by using the content of this creative specification and the drawings are included in the patent scope of this creation.
