Description

Technical Field

[0001] This utility model relates to the field of connector technology, and more specifically, to a socket connector. Background Technology

[0002] Some socket connectors, based on the need for short circuit and overload protection, usually have a fuse electrically connected between the terminal and the corresponding cable, so that the circuit can be quickly and effectively cut off in the event of a short circuit or overload, preventing adverse consequences such as burning and fire.

[0003] However, existing socket connectors with fuses usually require removing and installing the fuse from the end of the connector cable. Since the end of the connector is housed inside the device, removing and installing the fuse during vehicle maintenance is very difficult, time-consuming, and can easily interfere with other nearby devices. Utility Model Content

The first conductive element is detachably connected to the installation channel. One end of the first conductive element has a first mating portion and the other end has a first adapter portion. One end of the second conductive element has a first wiring portion and the other end has a second adapter portion. The fuse is connected to both the first adapter portion and the second adapter portion.

[0006] Optionally, the first conductive element is detachably connected to the mounting channel via a threaded structure.

[0007] Optionally, the first conductive element includes a mounting shell and a conductive body disposed within the mounting shell. The mounting shell and the mounting channel are detachably connected by a threaded structure, and the two ends of the conductive body in the axial direction respectively constitute the insertion portion and the first adapter portion.

[0009] Optionally, the first adapter has a plurality of radially extending first springs that elastically abut against the corresponding ends of the fuse.

[0010] Optionally, the mounting housing has a plug-in cavity at the end away from the fuse, and the plug-in portion of the conductor is housed in the plug-in cavity.

[0011] Optionally, the second adapter portion of the second conductive element is provided with a plurality of radially extending second springs, the second springs elastically abutting against the corresponding ends of the fuse.

[0012] Optionally, a sealing structure is integrally injection molded within the installation channel corresponding to the position of the second conductive component, and the portion of the second conductive component located between the first wiring portion and the second adapter portion is embedded in the sealing structure.

[0013] Optionally, a spring is also provided in the installation channel, with the two ends of the spring elastically abutting against the sealing structure and the fuse, respectively.

[0014] Optionally, the housing is further provided with a fixed channel, and a third conductive component is installed in the fixed channel. One end of the third conductive component forms a second plug-in part, and the other end forms a second wiring part.

[0036] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0037] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0038] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0039] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0040] like Figure 1-10 As shown, an embodiment of the present invention provides a socket connector, which includes a housing 1. The housing 1 has an installation channel 11 extending from the mating end to the other end. The installation channel 11 has a first conductive element 2, a fuse 3 and a second conductive element 5 arranged sequentially from the mating end to the other end.

[0041] The first conductive element 2 is detachably connected to the mounting channel 11. One end of the first conductive element 2 is provided with a first plug-in portion 221 and the other end is provided with a first adapter portion 223. One end of the second conductive element 5 is provided with a first wiring portion 51 and the other end is provided with a second adapter portion 53. The fuse 3 is connected to the first adapter portion 223 and the second adapter portion 53 respectively, so as to realize the electrical conduction of the first conductive element 2, the fuse 3 and the second conductive element 5.

[0042] The first conductive element 2, the fuse 3, and the second conductive element 5 are sequentially arranged from the mating end to the other end in the mounting channel 11 of the housing 1. The first conductive element 2 is detachably connected to the mounting channel 11. Therefore, when the fuse 3 needs to be removed and replaced, the fuse 3 can be removed simply by removing the first conductive element 2 from the mating end of the housing 1. This is convenient and quick, without the need to disassemble the housing 1, which improves the efficiency of disassembly and assembly and reduces maintenance costs. In addition, the detachable connection between the first conductive element 2 and the mounting channel 11 does not affect the insertion and removal of the mating plug connector, thus meeting basic functional requirements.

[0043] Furthermore, considering the reliability of the connection and the ease of assembly and disassembly, such as Figure 4-8 As shown, in this embodiment, the first conductive element 2 is detachably connected to the mounting channel 11 by a threaded structure, which includes an external thread 214 on the mounting housing 21 and an internal thread 16 on the mounting channel 11.

[0044] More specifically, considering electrical insulation performance and processing technology issues, such as Figure 7-8 As shown, in this embodiment, the first conductive element 2 includes a mounting shell 21 and a conductive body 22 disposed in the mounting shell 21. The mounting shell 21 is detachably connected to the mounting channel 11 by a threaded structure. The two ends of the conductive body 22 in the axial direction respectively constitute the above-mentioned insertion part and the first adapter part 223. The mounting shell 21 can be made of insulating material such as plastic, and the conductive body 22 can be embedded in the mounting shell 21 by injection molding.

[0045] Furthermore, to facilitate the positioning of the mounting housing 21 and prevent it from falling out of its correct position, such as... Figure 2 and Figure 5-8As shown, in this embodiment, the end of the mounting shell 21 away from the fuse 3 is provided with a radially extending overhang 212, and the mounting channel 11 is provided with a positioning part 13. When the mounting shell 21 is screwed into the predetermined position of the mounting channel 11, the overhang 212 and the positioning part 13 are engaged in a blocking engagement in the direction of rotation to prevent the mounting shell 21 from continuing to screw into the mounting channel 11. At the same time, the overhang 212 is snapped into the mounting channel 11 to prevent the mounting shell 21 from rotating in the opposite direction and being screwed out of the mounting channel 11. This snapping engagement can be achieved by the engagement of the protrusion 213 on the overhang 212 and the recess 14 on the mounting channel 11.

[0046] Furthermore, to ensure a good conductive connection between the first adapter 223 and the fuse 3 and prevent poor contact, the first adapter 223 has a plurality of radially extending first spring contacts 222. The first spring contacts 222 elastically abut against the corresponding ends of the fuse 3 to achieve a conductive connection, such as... Figure 4 , 7 As shown in Figures 9 and 1, in this embodiment, two first spring pieces 222 are provided, and the first spring pieces 222 are generally wavy.

[0047] Furthermore, considering the mating adaptation with the mating plug connector, such as Figure 1 , 2 As shown in Figures 4 and 8, in this embodiment, the end of the mounting shell 21 away from the fuse 3 is provided with a plug cavity 211. The mating part of the conductor 22 is housed in the plug cavity 211. The mating terminal part of the mating plug connector can be inserted into the plug cavity 211 to make conductive connection with the mating part.

[0048] Referring to the structure of the first adapter 223, the second adapter 53 of the second conductive member 5 is provided with a plurality of radially extending second spring pieces 52, which elastically abut against the corresponding ends of the fuse 3, such as... Figure 4 , 10 As shown, in this embodiment, two second spring pieces 52 are also provided, and the second spring pieces 52 as a whole are also wavy.

[0049] Furthermore, in order to secure the second conductive element 5 and simultaneously achieve a seal of the mounting channel 11 at the second conductive element 5, such as... Figure 3 , 4 As shown, in this embodiment, a sealing structure 15 is integrally injection molded in the installation channel 11 corresponding to the position of the second conductive element 5, and the part of the second conductive element 5 located between the first wiring part 51 and the second adapter part 53 is embedded in the sealing structure 15.

[0050] Furthermore, in order to achieve automatic ejection of fuse 3 and to facilitate the removal and replacement of fuse 3, such as... Figure 4As shown, in this embodiment, a spring 4 is also provided in the installation channel 11, and the two ends of the spring 4 elastically abut against the sealing structure 15 and the fuse 3 respectively.

[0051] Furthermore, considering scenarios involving two or more cores in the socket connector, such as the socket connector in this embodiment having a two-core structure, i.e., two conductive circuits, such as... Figure 4 , 5 As shown, a fixed channel 12 is also provided inside the housing 1, and a third conductive element 6 is installed in the fixed channel 12. One end of the third conductive element 6 forms a second plug-in part 61, and the other end forms a second wiring part 62.

[0052] like Figure 3 , 4 As shown, the portion of the housing 1 corresponding to the mounting channel 11 is designed to be extended and deformed so that the mounting channel 11 can be smoothly installed with the first conductive element 2, the fuse 3, and the second conductive element 5.

[0053] During assembly, the second conductive element 5 is pre-installed in the mounting channel 11. At this time, it is only necessary to install the fuse 3 in the mounting channel 11 and then install the first conductive element 2 into the mounting channel 11. During this process, the spring 4 is compressed. Then, the entire socket connector is installed in the desired position. When the fuse 3 is damaged and needs to be replaced, the first conductive element 2 is removed from the mating end of the housing 1. The spring 4 automatically pushes out the damaged fuse 3, exposing the fuse 3 in the mounting channel 11. Thus, the operator can easily remove the damaged fuse 3 and replace it with a new fuse 3. Then, the fuse 3 is reinstalled in the mounting channel 11 and the first conductive element 2 is installed. There is no need to disassemble the housing 1. The operation is convenient, the replacement is quick, and the time and labor costs required for maintenance are greatly reduced.
