[0007] Optionally, each elastic arm has a protrusion on one inner side; during the process of inserting the conductive element into the receiving channel, a portion of the conductive element can push against the protrusion to cause the elastic arm to elastically deform outward.

[0008] Optionally, at least a portion of the limiting groove of each conductive element is located in the receiving channel, and the engaging portion located in the limiting groove is correspondingly located in the receiving channel.

[0025] Please refer to the following: Figures 1 to 5 , Figure 1 and Figure 2 These are schematic diagrams from different perspectives of the first embodiment of the connector of this utility model. Figure 3 This is an exploded view of the first embodiment of the connector of this utility model.

[0026] The connector 100 of this utility model includes: an insulating body 10, three conductive elements 11, and an insulating limiting element 12. The number of conductive elements 11 included in the connector 100 can be varied according to actual needs and is not limited to what is shown in the figure.

[0027] The insulating body 10 has three receiving channels 101 inside, each channel 101 penetrating the insulating body 10. The insulating body 10 may also have four wall structures 102 inside, which, together with other structures of the insulating body 10, form the three receiving channels 101. A wall structure 102 separates two adjacent receiving channels 101. Through the design of the wall structures 102, most sections of the three receiving channels 101 are not interconnected. It should be noted that the number of receiving channels 101 inside the insulating body 10 can vary according to actual requirements and is not limited to three. In different embodiments, the insulating body 10 may also contain two or more receiving channels 101 inside.

[0028] Each receiving channel 101 forms a plug interface 101A and a connection port 101B at both ends of the insulating body 10. The plug interface 101A is used to provide the insertion of the conductive post of the mating connector, and the connection port 101B is used to provide the exit of the wire connected to the conductive element 11.

[0029] The insulating body 10 also has a side opening 103, through which each receiving channel 101 communicates with the external environment. In this embodiment, each wall structure 102 also has a groove 1021, and each groove 1021 communicates with the side opening 103.

[0030] Each conductive element 11 is disposed in each receiving channel 101. Each conductive element 11 has a limiting groove 111, which protrudes from the side opening 103. After the conductive element 11 is disposed in the receiving channel 101, the limiting groove 111 of the conductive element 11 will be correspondingly disposed with the groove 1021 of the wall structure 102. That is to say, the shape and size of the groove 1021 of the wall structure 102 are substantially the same as the shape and size of the limiting groove 111.

[0031] like Figure 5 As shown, in practical applications, the insulating body 10 can form a stop structure 104 in the section of each receiving channel 101 adjacent to the plug interface 101A. The stop structure 104 is used to abut a portion of the conductive member 11 to limit the range of movement of the conductive member 11 toward the plug interface 101A. Through the design of the stop structure 104, when the assembly personnel install the conductive member 11 into the receiving channel 101, if the conductive member 11 is blocked by the stop structure 104 and cannot easily move toward the plug interface 101A, the assembly personnel can know that the conductive member 11 has been installed in the correct position.

[0032] In other words, the design of the stop structure 104 ensures that the conductive element 11 is correctly installed in the default position, and that the limiting groove 111 of the conductive element 11 can be correctly connected with the side opening 103. This ensures that the engaging part 122 of the insulating limiting element 12 can smoothly pass through the side opening 103 and be placed in the limiting groove 111.

[0033] Each conductive element 11 has a limiting structure 113 located in the side opening 103, and the limiting structure 113 is located below a stop portion 1051 of the insulating body 10. More specifically, when the conductive element 11 is installed in the receiving channel 101, a part of the limiting structure 113 of the conductive element 11 is located directly below the stop portion 1051 of the insulating body 10. With this design, when the conductive element 11 is subjected to external force and wants to move towards the connection port 101B, the limiting structure 113 of the conductive element 11 will abut against the stop portion 1051, so that the conductive element 11 cannot easily leave the receiving channel 101.

[0034] In practical applications, the insulating body 10 may include multiple elastic arms 105, with the free ends of the multiple elastic arms 105 located at the side opening 103. The free end of each elastic arm 105 serves as abutment 1051. Each elastic arm 105 may have a protrusion 1052 on its inner side. During the process of inserting the conductive member 11 into the receiving channel 101, the limiting structure 113 of the conductive member 11 can push against the protrusion 1052, causing the elastic arm 105 to elastically deform outward.

[0035] More specifically, during the insertion of the conductive element 11 into the receiving channel 101, the limiting structure 113 of the conductive element 11 pushes against the protrusion 1052, causing the elastic arm 105 to elastically deform away from the receiving channel 101. When the limiting structure 113 passes through the protrusion 1052 and enters the side opening 103, the protrusion 1052 is no longer pushed against by the limiting structure 113, and the elastic arm 105, under the action of elastic restoring force, will return to the state where it was not pushed against by the limiting structure 113. When the elastic arm 105 returns to the state where it was not pushed against by the limiting structure 113, the free end (abutment portion 1051) of the elastic arm 105 will be located directly above the limiting structure 113. That is to say, a part of the limiting structure 113 is located within the orthogonal projection range of the elastic arm 105 toward the limiting structure 113. With this design, when the conductive component 11 is subjected to external force and attempts to leave the receiving channel 101 through the connection port 101B, the limiting structure 113 will be blocked by the free end of the elastic arm 105 and will not be able to easily leave the receiving channel 101. At the same time, the engaging part 122 of the insulating limiting component 12 will also restrict the conductive component 11 from leaving the receiving channel 101.

[0036] like Figure 3As shown, each side of the insulating body 10, near the side opening 103, may have a first engaging structure 106. The insulating limiting member 12 includes a body 121, a single engaging portion 122, and two second engaging structures 123. The body 121 may generally have a C-shaped structure, with the engaging portion 122 located in the middle section of the C-shaped structure, and the two second engaging structures 123 corresponding to the inner sides of the two arms of the C-shaped structure. The two second engaging structures 123 are used to engage with the two first engaging structures 106, thereby fixing the insulating limiting member 12 to the insulating body 10. The dimensions, positions, and engaging methods of the first engaging structures 106 and the second engaging structures 123 are not limited to those shown in the figure and can be varied according to actual needs.

[0037] After the insulating limiting member 12 is fixed to the insulating body 10, the insulating limiting member 12 will correspond to the shielding side opening 103, and the engaging part 122 will be located in the limiting groove 111 of each conductive member 11 and the groove 1021 of each wall structure 102. The engaging part 122 can be used to limit the range of movement of each conductive member 11 relative to the insulating body 10.

[0038] It is worth mentioning that at least a portion of the limiting groove 111 of each conductive element 11 is located in the receiving channel 101, and the engaging portion 122 located in the limiting groove 111 is correspondingly located in the receiving channel 101. That is to say, a portion of the engaging portion 122 is correspondingly located in the receiving channel 101. This design makes it more difficult for the conductive element 11 to leave the insulating body 10.

[0039] As described above, by engaging the locking portion 122 of the insulating limiting member 12 with the limiting grooves 111 of each conductive member 11, it can be ensured that the conductive member 11 is not easily separated from the insulating body 10 by slight external forces. Moreover, by engaging the locking portion 122 in the grooves 1021 of each wall structure 102, the insulating body 10, the conductive member 11, and the locking portion 122 are mutually engaged, which further prevents the conductive member 11 from easily separating from the insulating body 10 by external forces.

[0040] like Figure 3 As shown, in practical applications, the insulating body 10 can also have a support platform structure 107, which is used to support the insulating limiting member 12. That is, after the insulating limiting member 12 is fixed to the two first engaging structures 106 of the insulating body 10 through the two second engaging structures 123, the insulating limiting member 12 is also supported by the support platform structure 107, which increases the contact area between the insulating limiting member 12 and the insulating body 10. In this way, the probability of the insulating limiting member 12 detaching from the insulating body 10 can be further reduced.

[0041] Each conductive element 11 may also have a support platform structure 112 and two limiting structures 113. The two limiting structures 113 and the support platform structure 112 together form a limiting groove 111. The support platform structure 112 is used to support the engaging portion 122. In one embodiment, each conductive element 11 may be formed by bending a conductive sheet, and the two connecting structures 114 on both sides of the conductive sheet are bent and engaged with each other to jointly form the support platform structure 112. Through the design of the support platform structure 112, the contact area between the conductive element 11 and the engaging portion 122 can be increased, thereby strengthening the connection strength between the conductive element 11 and the engaging portion 122.

[0042] Please refer to the following: Figure 6 and Figure 7 , Figure 6 This is an exploded and partial cross-sectional schematic diagram of the second embodiment of the connector of this utility model. Figure 7 This is a cross-sectional schematic diagram of the second embodiment of the connector of this utility model.

[0043] One difference between this embodiment and the previous embodiment is that the insulating limiting member 12 includes three engaging portions 122, which are spaced apart from each other. The number of engaging portions 122 included in the insulating limiting member 12 is not limited to that shown in the figure.

[0044] When the insulating limiting member 12 and the insulating body 10 engage with each other, each engaging portion 122 is engaged in the limiting groove 111 of each conductive member 11 through the side opening 103, and each engaging portion 122 is correspondingly located in each receiving channel 101. In other words, the width of each engaging portion 122 is less than the straight-line interval between two adjacent wall structures 102, and each engaging portion 122 is correspondingly located between two adjacent wall structures 102. In this embodiment, each wall structure 102 may not have a groove.

[0045] It should be noted that, in this embodiment, the number of engaging portions 122 included in the insulating limiting member 12, the number of receiving channels 101 included in the insulating body 10, and the number of conductive members 11 are the same, but this is not a limitation. In different embodiments, the number of engaging portions 122 included in the insulating limiting member 12 and the number of conductive members 11 may also be different. For example, the connector 100 includes two conductive members 11, while the insulating limiting member 12 includes three engaging portions 122.

[0046] Please see Figure 8 The diagram shows an exploded view of the connector assembly of this invention. The connector assembly Z of this invention includes the connector 100 and a mating connector 200. For a description of the connector 100, please refer to the foregoing description; it will not be repeated here.

[0047] The mating connector 200 includes an insulating body 20, three receiving channels 21, and three conductive elements 22. The insulating body 20 has three receiving channels 21, and the three conductive elements 22 are disposed in the insulating body 20. A portion of each of the three conductive elements 22 is located in one of the three receiving channels 21, and a portion of each of the three conductive elements 22 is exposed outside the insulating body 20.

[0048] The insulating body 10 of the connector 100 may also include a first foolproof structure 108, and the mating connector 200 includes a second foolproof structure 23. The first foolproof structure 108 is used to engage with the second foolproof structure 23, and the first foolproof structure 108 and the second foolproof structure 23 can jointly restrict the insertion direction of the connector 100 and the mating connector 200.

[0049] For example, the first foolproof structure 108 can be a protruding structure formed on one side of the insulating body 10, while the other side of the insulating body 10 has no protruding structure. The second foolproof structure 23 of the mating connector 200 can be a recessed structure. When the connector 100 and the mating connector 200 are correctly connected, the first foolproof structure 108 can be inserted into the recessed structure (second foolproof structure 23). Conversely, when the connector 100 and the mating connector 200 are not connected correctly, the connector 100 will be unable to be connected to the other connector due to the first foolproof structure 108, thereby achieving the foolproof effect.

[0050] When the mating connector 200 and the connector 100 are plugged into each other, the three conductive parts 22 of the mating connector 200 will enter the three receiving channels 101 through the three plug interfaces 101A of the connector 100 and connect with the three conductive parts 11 of the connector 100.

[0051] In summary, the connector and connector assembly of this utility model, through the design of the limiting groove and limiting structure of the conductive component, combined with the side opening of the insulating body and the engaging part of the insulating limiting component, can prevent the conductive component of the connector from easily detaching from the insulating body.

[0052] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Therefore, all equivalent technical changes made based on the contents of the present utility model specification and drawings are included within the protection scope of the present utility model.
