Detailed Description

Embodiments of the present invention are described in detail below, with reference to the accompanying drawings, which are exemplary, and contacts 100 of an electrical connector according to an embodiment of the first aspect of the present invention are described below with reference to fig. 1-14.

As shown in fig. 1 and 3, a contact 100 for an electrical connector according to an embodiment of the first aspect of the present invention includes a body 1.

Specifically, a plugging channel 11 is formed on the main body 1, one end of the plugging channel 11 is a socket 111, a plurality of groups of elastic components 2 are arranged in the plugging channel 11, and the plurality of groups of elastic components 2 are arranged along the length direction (for example, the front-back direction of fig. 1) of the main body 1. For example, in the example of fig. 1, a plugging passage 11 penetrating in the longitudinal direction of the main body 1 is formed in the main body 1, the above-mentioned one end of the plugging passage 11 is the front end of the plugging passage 11, and the plurality of sets of elastic members 2 are arranged in a direction away from the socket 111. When the contact 100 is used in an electrical connector, the electrical terminals 200 of the electrical connector may be inserted into the insertion channels 11 from the insertion openings 111 to contact the sets of spring assemblies 2, and the electrical connection of the electrical connector may be achieved by the contact of the electrical terminals 200 with the spring assemblies 2. In addition, by providing a plurality of groups of elastic members 2, when one or more groups of elastic members 2 are connected and fail due to slight deformation of the elastic members 2 caused by slight unreformed force, the electrical terminal 200 can be electrically connected through other elastic members 2 which are not deformed (for example, the elastic members 2 near the front ends of the contacts 100 fail due to slight deformation of the front portions of the contacts 100 caused by external force), and other elastic members 2 far from the front ends of the contacts 100 can still be in contact with the electrical terminals 200 to form electrical connection), thereby improving the reliability of the use of the contacts 100 and further improving the reliability of the use of the electrical connector. Moreover, the electrical connector is enabled to accommodate more complex use environments. In addition, the plurality of groups of elastic components 2 are arranged along the direction away from the socket 111, that is, the plurality of groups of elastic components 2 are arranged along the assembly direction of the electrical terminal 200 and the contact 100, so that the electrical terminal 200 can be smoothly inserted into the plugging channel 11, and the plugging and unplugging of the electrical terminal 200 are facilitated.

Referring to fig. 5 and 7, each set of elastic members 2 includes at least one elastic piece 21, one end of the elastic piece 21 is connected to the plugging channel 11, and the other end of the elastic piece 21 extends obliquely toward the direction of the central axis of the plugging channel 11 (i.e., the front-rear direction). For example, when the above-mentioned one end of the elastic piece 21 is connected to the bottom wall of the plugging channel 11, the above-mentioned other end of the elastic piece 21 extends obliquely from bottom to top and back (as shown in fig. 7), and of course, the above-mentioned other end of the elastic piece 21 may also be arranged to extend obliquely from bottom to top and back (not shown); when the one end of the elastic piece 21 is connected to the right side wall of the plugging channel 11, the other end of the elastic piece 21 extends obliquely from right to left to back (not shown), or the other end of the elastic piece 21 extends obliquely from right to left to front (not shown). When the electrical terminal 200 is inserted into the insertion passage 11, the electrical terminal 200 is in contact with the other end of the elastic piece 21. So set up, on the one hand, the shell fragment 21 can form dodging to electric terminal 200, is favorable to electric terminal 200 to insert in the grafting passageway 11 when guaranteeing electric terminal 200 and shell fragment 21 contact, and electric terminal 200 also can be pulled out smoothly in the grafting passageway 11 simultaneously to be favorable to the assembly and the dismantlement of contact 100 and electric terminal 200. On the other hand, the spring piece 21 has a simple structure, which is beneficial to the production and processing of the contact 100.

According to the contact 100 for the electric connector, the contact 100 is simple in structure and convenient to produce and process. By providing a plurality of sets of elastic members 2 arranged in a direction away from the socket 111 in the mating passage 11, the reliability of use of the contact 100 is improved. When the contact 100 is used in an electrical connector, connection reliability of the electrical connector is improved, and the electrical connector can be adapted to a more complex use environment, thereby improving the use performance of the electrical connector. In addition, the electrical terminal 200 is easily inserted into the insertion passage 11, and the electrical terminal 200 is easily inserted and removed, thereby facilitating the assembly and disassembly of the contact 100 and the electrical terminal 200.

According to some embodiments of the present invention, in connection with fig. 7, each set of elastic members 2 comprises a plurality of elastic pieces 21, the plurality of elastic pieces 21 comprising a first elastic piece 22 and a second elastic piece 23, in the description of the present invention, "plurality" means two or more. The first elastic piece 22 and the second elastic piece 23 are respectively located on two side walls (for example, an upper side wall and a lower side wall of the plugging channel 11, where the side walls are inner wall surfaces of the plugging channel 11) of the plugging channel 11 opposite to each other, and the first elastic piece 22 and the second elastic piece 23 are close to each other in a direction toward and away from the socket 111. For example, in the example of fig. 7, each set of elastic components 2 includes two elastic pieces 21, and the first elastic piece 22 and the second elastic piece 23 are respectively located on two opposite upper and lower sidewalls of the plugging channel 11, where the structure of the first elastic piece 22 and the structure of the second elastic piece 23 are substantially the same. As shown in fig. 7, when the electrical terminal 200 is inserted into the plugging channel 11, opposite side surfaces of the electrical terminal 200 are respectively contacted with the first elastic piece 22 and the second elastic piece 23, so as to realize connection between the electrical terminal 200 and the elastic component 2. Thus, the electrical terminal 200 has a plurality of contact points with each group of elastic components 2, and the electrical terminal 200 can be simultaneously contacted with a plurality of groups of elastic components 2, so that the number of contact points of the electrical terminal 200 and the contact 100 is increased, and the connection reliability of the contact 100 is further improved. In addition, through the combined action of the opposite elastic sheets 21, the connection firmness of the electric terminal 200 and each group of elastic assemblies 2 is enhanced, and the normal use of the contact 100 is facilitated. It should be noted that the number of the elastic pieces 21 may be specifically set according to the use situation, so as to better satisfy the practical application.

According to some embodiments of the present invention, referring to fig. 9, the distances between the ends of the first elastic piece 22 and the second elastic piece 23, which are close to each other, in the plurality of sets of elastic assemblies 2 are equal. For example, in the example of fig. 9, the elastic components 2 are provided with three groups, each group of elastic components 2 includes a first elastic piece 22 and a second elastic piece 23, and distances between ends of the first elastic piece 22 and the second elastic piece 23 of the three groups, which are close to the central axis of the plugging channel 11, are h ₁、h₂ and h ₃, respectively, where h ₁、h₂ and h ₃ satisfy: h ₁＝h₂＝h₃. When the electric terminal 200 is inserted into the plugging channel 11, the acting force of each group of elastic components 2 on the electric terminal 200 is approximately the same, and the reaction force born by each elastic piece 21 in the plugging process of the electric terminal 200 is also approximately the same, so that the long-term stable use of a plurality of elastic pieces 21 is facilitated. In addition, the arrangement of each group of elastic assemblies 2 is approximately the same, which is beneficial to mass production and processing of the contacts 100 and can improve the production efficiency of the contacts 100. It should be noted that, the distance between the ends of the first elastic piece 22 and the second elastic piece 23 that are close to each other may be specifically set according to the use situation, so as to better satisfy the practical application.

According to other embodiments of the present invention, the distances between the ends of the first and second elastic pieces 22, 23 of the plurality of sets of elastic members 2 that are close to each other decrease in order in a direction toward the socket 111 (not shown). For example, when the elastic assembly 2 is in three groups, h ₁、h₂ and h ₃ satisfy: h ₁＞h₂＞h₃. By the arrangement, the contact between the electric terminals 200 and the elastic assemblies 2 is facilitated, and meanwhile, the plugging hand feeling is different when the electric terminals 200 are plugged. Moreover, the electrical terminal 200 is not easily detached from the insertion passage 11, which is advantageous for the long-term stable use of the contact 100.

According to other embodiments of the present invention, the distances between the ends of the first and second elastic pieces 22, 23 of the plurality of sets of elastic members 2 that are close to each other increase in order in a direction away from the socket 111 (not shown). For example, when the elastic assembly 2 is in three groups, h ₁、h₂ and h ₃ satisfy: h ₁＜h₂＜h₃. Thus, the contact between the electric terminals 200 and the elastic components 2 is facilitated, and the plugging hand feeling is different when the electric terminals 200 are plugged. In addition, the removal of the electrical terminal 200 from the contact 100 is facilitated even more, thereby facilitating the replacement of the contact 100 or the electrical terminal 200.

According to some embodiments of the present invention, the first elastic piece 22 and the second elastic piece 23 of each set of elastic members 2 are opposite to each other in the arrangement direction of the two side walls of the plugging channel 11 opposite to each other. For example, in the examples of fig. 7, 9, 12 and 13, the first elastic piece 22 and the second elastic piece 23 are respectively connected to the bottom wall and the top wall of the plugging channel 11, and the first elastic piece 22 and the second elastic piece 23 are opposite to each other in the up-down direction. The arrangement of the first elastic sheet 22 and the second elastic sheet 23 of the plurality of groups of elastic assemblies 2 is tidy, which is beneficial to the production and processing of the contact 100.

According to other embodiments of the present invention, the first elastic piece 22 and the second elastic piece 23 of each set of elastic members 2 are staggered in the arrangement direction of the two side walls of the plugging channel 11 opposite to each other. For example, in the example of fig. 10, the first elastic piece 22 and the second elastic piece 23 are respectively connected to the bottom wall and the top wall of the plugging channel 11, and the first elastic piece 22 and the second elastic piece 23 are staggered in the up-down direction. Therefore, when the electric terminal 200 is inserted into the plugging channel 11, the plurality of contact sites on the electric terminal 200 are arranged at intervals along the front-rear direction, so that the plugging force can be reduced, the electric terminal 200 can be smoothly inserted into the plugging channel 11, the assembly of the electric terminal 200 and the contact 100 is facilitated, and the plugging hand feeling of the electric terminal 200 can be improved.

Further, referring to fig. 5 and 8, the first elastic piece 22 includes two elastic piece portions 221, one ends of the two elastic piece portions 221 are connected to the plugging channel 11, and the above-mentioned ends of the two elastic piece portions 221 are spaced apart from each other, extend obliquely in a direction away from the socket 111, and the other ends of the two elastic piece portions 221 are connected to each other toward a central axis of the plugging channel 11. For example, in the examples of fig. 5 and 8, the first elastic piece 22 is connected to the bottom wall of the plugging channel 11, the one ends of the two elastic piece portions 221 are spaced apart in the left-right direction, the other ends of the two elastic piece portions 221 extend toward the central axis of the plugging channel 11 and are connected, and the two elastic piece portions 221 together constitute the first elastic piece 22 having a substantially triangular shape (or a fish scale shape). By the arrangement, while the first elastic piece 22 is ensured to be in contact with the electric terminal 200, the stress of the electric terminal 200 to the first elastic piece 22 can be released to the one ends of the two elastic piece parts 221 respectively, so that the permanent deformation yield caused by irreversible plastic deformation due to the stress is reduced, the reliability of the first elastic piece 22 in long-term use is improved, the damage of the first elastic piece 22 is reduced, and the service life of the contact 100 is prolonged. Moreover, when the contact 100 is used in an electrical connector, the electrical connector may be used in a more complex, higher performance demanding use environment (e.g., when the use environment of the electrical connector is a vibration-rich environment). In addition, the structure of the spring plate part 221 is simple, so that the material of the spring plate part 221 can be saved, and the use cost of the spring plate part 221 is reduced. The structure of the second spring 23 is substantially the same as that of the first spring 22, and will not be described in detail here.

According to some embodiments of the present application, referring to fig. 5, 6 and 8, the connection hole 112 is formed on the sidewall of the plugging channel 11, and the one ends of the two elastic sheet parts 221 are connected to the sidewall of the connection hole 112 at a distance from each other. For example, in the examples of fig. 5 and 8, the first elastic piece 22 and the second elastic piece 23 are respectively provided on two side walls of the plugging channel 11 in the up-down direction, that is, the bottom wall and the top wall of the plugging channel 11, and the bottom wall and the top wall of the plugging channel 11 are each formed with a connection hole 112 penetrating in the up-down direction. When the electrical terminal 200 is inserted into the insertion passage 11, the ends of the two spring piece portions 221 of the first spring piece 22 and the second spring piece 23 connected to each other move in a direction away from the central axis of the insertion passage 11 under the force of the electrical terminal 200, so that the electrical terminal 200 is fixed in the insertion passage 11. When the electric terminal 200 is pulled out from the plugging channel 11, the first elastic piece 22 and the second elastic piece 23 recover to deform. Thus, by providing the connection hole 112, the two spring piece portions 221 are favorably deformed in the up-down direction, thereby facilitating insertion and extraction of the electrical terminal 200. For example, the width of the first elastic sheet 22 is a, the length of the first elastic sheet 22 is b, and in the embodiment of the application, a=0.5 mm, b=1.65 mm, but not limited thereto. Alternatively, the length b and the width a may be adjusted according to the use requirement, so that more groups of elastic members 2 may be provided on the premise of the same size of the contact 100. For example, the size of the connection hole 112 may be reduced by appropriately reducing the length b of the first elastic piece 22 and the width a of the first elastic piece 22, thereby reducing the adjacency; the spacing of the two sets of elastic members 2 in the front-rear direction can be achieved, so that more sets of elastic members 2 can be realized.

According to some embodiments of the present invention, in connection with fig. 12, the other end of the spring plate 21 is provided with a bending portion 211, and the bending portion 211 extends obliquely in a direction away from the socket 111 and in a direction away from the central axis of the plugging channel 11. For example, in the example of fig. 12, the ends of the first elastic piece 22 and the second elastic piece 23 of the plurality of sets of elastic members 2, which are close to each other, are each provided with a bent portion 211. Thereby, the structural strength of the spring piece 21 is enhanced, which is beneficial to the long-term stable use of the spring piece 21. Moreover, the contact performance of the electrical terminal 200 and the spring piece 21 can be improved. Alternatively, the side of the bent portion 211 facing the central axis of the mating passage 11 is formed as an arc surface. Thereby, the friction between the electrical terminal 200 and the spring piece 21 is reduced, which is advantageous for the long-term use of the contact 100 and the electrical terminal 200. In addition, the electrical terminal 200 has a good plugging feel.

According to some embodiments of the present invention, referring to fig. 10 and 13, the other end of the spring plate 21 is provided with a protrusion 212, and the protrusion 212 protrudes toward the central axis of the plugging channel 11. For example, in the example of fig. 10 and 13, the end of the spring piece 21 near the center axis of the plugging channel 11 is provided with a protruding portion 212. Thus, the contact between the protruding portion 212 and the electrical terminal 200 is substantially point contact, the contact performance is improved, and the electrical connection between the spring piece 21 and the electrical terminal 200 is facilitated. The protruding portion 212 may be formed by protruding the elastic piece portion 221 toward the central axis direction of the plugging channel 11, or the protruding portion 212 may be formed by protruding the connection portion of the elastic piece portion 221 and the bending portion 211 toward the central axis direction of the plugging channel 11. But is not limited thereto. By this arrangement, the structure of the boss 212 is simple, thereby simplifying the structure of the contact 100 and further improving the production efficiency of the contact 100.

Alternatively, a side surface of the boss 212 facing the central axis of the mating passage 11 is formed as an arc surface. So set up, on the one hand, be favorable to the contact of electric terminal 200 and shell fragment 21 more, the contact is better to be favorable to the normal use of contact 100 more. On the other hand, the friction force between the protruding part 212 and the electric terminal 200 is smaller, so that the electric terminal 200 can be inserted into the plugging channel 11 more smoothly, and the electric terminal 200 is more beneficial to the matching with the contact 100.

According to some embodiments of the present invention, the angle between the spring plate 21 and the corresponding side wall of the plugging channel 11 is α, where α satisfies: alpha is more than or equal to 5 degrees and less than or equal to 20 degrees. For example, in the example of fig. 12, the first spring 22 is disposed on the bottom wall of the plugging channel 11, and the angle between the first spring 22 and the bottom wall of the plugging channel 11 is α. When the included angle between the spring piece 21 and the corresponding side wall of the plugging channel 11 is smaller than 5 °, the smaller included angle can easily cause the contact force between the spring piece 21 and the electrical terminal 200 to be smaller, thereby affecting the performance of the electrical terminal 200. Thereby, by arranging the angle α between the spring plate 21 and the corresponding side wall of the plugging channel 11 is satisfied: the angle alpha is more than or equal to 5 degrees and less than or equal to 20 degrees, so that the influence of residual stress caused by processing on the elastic sheet 21 can be effectively reduced while the contact between the elastic sheet 21 and the electric terminal 200 is ensured, and the long-term use of the elastic sheet 21 is facilitated. It should be noted that, the included angle between the elastic piece 21 and the corresponding side wall of the plugging channel 11 may be set according to the size of the actual elastic piece 21 and specific use requirements, so as to better satisfy practical application. In this embodiment, the angle α between the spring plate 21 and the corresponding sidewall of the plugging channel 11 is 15 °.

Further, referring to fig. 1 and 3, at least one limiting boss 113 is provided on an inner wall surface of the plugging channel 11, and the limiting boss 113 is located between the socket 111 and the plurality of groups of elastic components 2. For example, a limiting boss 113 is provided on the bottom wall of the plugging channel 11, and the limiting boss 113 protrudes toward the central axis direction of the plugging channel 11. Therefore, the limiting boss 113 can have a limiting effect on the electric terminal 200, so that the electric terminal 200 can extend in the horizontal direction in the process of inserting the electric terminal 200 into the plugging channel 11 from the socket 111, abnormal increase of the insertion force of the electric terminal 200 caused by scratch generated between the electric terminal 200 and the side wall of the plugging channel and functional failure of the elastic sheet 21 caused by excessive bias of the first elastic sheet 22 and the second elastic sheet 23 when the electric terminal 200 is obliquely inserted are avoided, and accordingly matching of the electric terminal 200 and the contact 100 is more facilitated.

For example, in the example of fig. 1 and 3, one limiting boss 113 is provided on each of the four inner wall surfaces of the plugging channel 11, and a plurality of limiting bosses 113 are provided between the socket 111 and the plurality of sets of elastic members 2. Therefore, through the combined action of the plurality of limiting bosses 113, the limiting accuracy of the limiting bosses 113 to the electric terminal 200 is improved, stable insertion of the electric terminal 200 into the inserting channel 11 from the inserting opening 111 is ensured, the problems of scratch of the electric terminal 200 and the inner wall of the inserting channel 11 and uneven stress of different elastic sheets 21 are effectively prevented, and accordingly the assembly of the electric terminal 200 and the contact 100 is facilitated.

According to some embodiments of the present invention, in connection with fig. 1, at least one fool-proof structure 12 is provided on the outer circumferential surface of the main body 1. For example, in the example of fig. 1, the body 1 is provided with a fool-proof structure 12 on one side. Thus, when the contact 100 is used in a connector, functional failure due to misloading of the contact 100 with other components can be effectively prevented, thereby improving the assembly efficiency of the electrical connector. For example, the fool-proof structure 12 may be formed by a side surface of the main body 1 protruding in a direction away from the main body 1. With this arrangement, the fool-proof structure 12 is simple in structure and convenient to manufacture and process, and the use cost of the fool-proof structure 12 is low, so that the production cost of the contact 100 is reduced.

According to some embodiments of the present invention, referring to fig. 1, 3 and 5, the body 1 includes a first body plate 13, two side plates 14, a second body plate 15 and a third body plate 16, the two side plates 14 are respectively connected to both sides of the first body plate 13 in a width direction (i.e., a left-right direction), the two side plates 14 are located at a side of the first body plate 13 facing a center of the body 1, the second body plate 15 is connected to a side of one of the two side plates 14 facing away from the first body plate 13, and a side of the second body plate 15 facing the center of the body 1 is opposite to a side of the first body plate 13 facing the center of the body 1, the third body plate 16 is connected to the other of the two side plates 14, and the third body plate 16 is located at a side of the second body plate 15 facing away from the first body plate 13. For example, in the examples of fig. 1, 3 and 5, the first body plate 13, the two side plates 14, the second body plate 15 and the third body plate 16 together construct the rectangular body 1, the second body plate 15 is connected to the side plate 14 on the right side of the first body plate 13, the third body plate 16 is connected to the side plate 14 on the left side of the first body plate 13, the second body plate 15 and the third body plate 16 are stacked in the up-down direction, and the third body plate 16 is located above the second body plate 15. The first body plate 13, the two side plates 14 and the second body plate 15 together define the plugging channel 11, the side surface of the first body plate 13 facing the second body plate 15, and the side surface of the second body plate 15 facing the first body plate 13 may be two side walls of the plugging channel 11 opposite to each other as described above (for example, the side surface of the first body plate 13 facing the second body plate 15 is a lower side wall of the plugging channel 11, and the side surface of the second body plate 15 facing the first body plate 13 is an upper side wall of the plugging channel 11). So set up, the simple structure of main part 1, production and processing is convenient to the low in production cost of main part 1, excellent performance is favorable to the popularization and use of contact 100. Alternatively, the body 1 is an integrally molded piece, but is not limited thereto.

According to some embodiments of the invention, fig. 3 is combined. At least one positioning member 151 is provided at one end of the second body plate 15 adjacent to the other of the two side plates 14, at least one positioning hole 141 is formed at the junction of the other of the two side plates 14 and the third body plate 16, and the positioning member 151 is fitted in the positioning hole 141. For example, in the example of fig. 3, the positioning piece 151 is connected to the left side of the second body plate 15, and the positioning hole 141 is formed at the connection of the side plate 14 and the third body plate 16 on the left side of the first body plate 13. This strengthens the connection between the second body panel 15 and the brackets of the third body panel 16 and the side panels 14, and the connection is more secure. In addition, the supporting effect of the second body plate 15 on the third body plate 16 is enhanced, so that the excessive bias of the third body plate 16 can be placed, the structural strength of the body 1 is enhanced, and the long-term stable use of the body 1 is facilitated.

Alternatively, referring to fig. 3, the positioning member 151 and the positioning hole 141 are each plural, and the plural positioning members 151 are respectively fitted in the plural positioning holes 141. Thereby, the supporting effect of the second body plate 15 on the third body plate 16 is further enhanced by the cooperation of the plurality of positioning pieces 151 and the plurality of positioning holes 141, and the structural strength of the body 1 is further enhanced.

Further, with reference to fig. 1 and 3, the contact 100 includes a crimp member 3, the crimp member 3 being connected to an end of the body 1 remote from the socket 111. For example, in the examples of fig. 1 and 3, the crimp 3 is connected to the rear end of the main body 1. When the contact 100 is used in an electrical connector, a plurality of wires may be placed on the crimp 3 to connect with the body 1, thereby facilitating connection of the contact 100 with the wires to facilitate normal use of the contact 100. In addition, the wires are not easy to intertwine, so that the normal use of the wires is facilitated.

According to some embodiments of the present invention, referring to fig. 1 and 3, the crimp 3 includes a conductor clip 31 and an insulation clip 32 connected to each other, the conductor clip 31 being connected between the body 1 and the insulation clip 32. For example, in the examples of fig. 1 and 3, the main body 1, the conductor clip 31, and the insulating clip 32 are sequentially from front to back. When the contact 100 is used in an electrical connector, the two free ends of the insulating clip 32 are brought close to each other to fix the wires, the insulating housing of the plurality of wires is in contact with the inner wall surface of the conductor clip 31, and the plurality of wires are wrapped by the insulating clip 32 while the conductors of the plurality of wires are in contact with the conductor clip 31, the two free ends of the conductor clip 31 are brought close to each other to make the outer peripheral surface of the conductor clip 31 substantially annular, and the plurality of wires are wrapped in the conductor clip 31. Thereby facilitating connection of the crimp 3 to the wire and thus facilitating use of the contact 100. In addition, the connection between the crimping member 3 and the wire is relatively tight while facilitating normal conduction of the wire, and the use safety of the contact 100 is improved by providing the insulating wire clamp 32.

Optionally, the free end of the outer circumferential surface of the conductor clip 31 has a first chamfer 311 and/or the free end of the outer circumferential surface of the insulating clip 32 has a second chamfer 321.

The above-described arrangement of the first chamfer 311 and the second chamfer 321 includes the following three cases: the free end of the outer peripheral surface of the first, conductor clip 31 alone has a first chamfer 311 (not shown). The free end of the outer peripheral surface of the second, insulating clip 32 only has a second chamfer 321 (not shown). Third, the free end of the outer peripheral surface of the conductor clip 31 has a first chamfer 311, and the free end of the outer peripheral surface of the insulating clip 32 has a second chamfer 321 (as shown in fig. 1-3). So configured, when the conductor clamp 31 is crimped to a wire, interference between the two free ends of the conductor clamp 31 can be avoided, thereby facilitating the two free ends of the conductor clamp 31 (e.g., the left and right ends of the conductor clamp 31 in fig. 1) to be brought close to each other to crimp the wire so that the wire is fixed to the conductor clamp 31. In addition, when the insulating clip 32 is crimped to the wire, interference between the two free ends of the insulating clip 32 can be effectively avoided by providing the second chamfer 321, thereby facilitating the two free ends of the insulating clip 32 (e.g., the left and right ends of the insulating clip 32 in fig. 1 and 3) to approach each other and construct an annular insulating clip 32, thereby facilitating the cooperation of the wire and the insulating clip 32.

According to some embodiments of the present invention, referring to fig. 1 to 3, at least one groove 312 is formed on an inner wall surface of the conductor clip 31, the groove 312 extending in a circumferential direction of a central axis of the mating passage 11. For example, in the example of fig. 1 and 3, the grooves 312 are plural, and the plural grooves 312 are arranged at intervals in the front-rear direction, each groove 312 extending in the circumferential direction of the conductor clip 31. Thereby, when a plurality of wires are fitted at the inner peripheral side of the conductor clamp 31 in the direction of the central axis of the insertion passage 11, the friction force between the inner wall surface of the conductor clamp 31 and the wires is increased, so that the wires are less likely to fall off from the inner peripheral side of the conductor clamp 31, and the connection stability of the wires and the conductor clamp 31 is improved. It should be noted that the depth of each groove 312 and the distance between two adjacent grooves 312 may be specifically set according to the use situation, so as to better satisfy the practical application.
