Description

Technical Field

[0001] This utility model belongs to the field of electrical connectors, and specifically relates to a housing and an electrical connector. Background Technology

[0002] Most existing electrical connectors have their internal components (conductive parts and signal pins, etc.) installed from the rear, and a back cover or pressure plate is used to prevent them from falling off in the front or back direction. However, the back cover or pressure plate needs to be pre-installed on the cable to achieve the desired effect, which is a complex process and inconvenient to produce.

[0003] Moreover, the back cover or pressure plate is relatively thin. When it is pre-installed on the cable and then the conductive parts are riveted or welded, the back cover or pressure plate is easily damaged during operation, resulting in a low product yield. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, this utility model designs a housing for an electrical connector that fixes the conductive component from the front end, and an electrical connector having the above structure.

[0005] The technical solution of this utility model is as follows:

[0006] The housing of the electrical connector includes a main plastic shell, on which an insertion part is provided. At least one mounting hole for mounting a conductive component is provided on the end face of the insertion part. The housing also includes a cover connected to the insertion part, which is used to fix the conductive component in the mounting hole. The cover is provided with a plug-in through hole corresponding to the mounting hole.

[0007] Furthermore, the end face of the insertion part is provided with two mounting holes for installing conductive components, and the cover is provided with two insertion through holes, which correspond to the mounting holes respectively.

[0008] Furthermore, the end face of the insertion part is provided with two mounting holes for installing conductive components, and the end face of the insertion part between the two mounting holes is provided with a second mounting hole for installing a signal module. The cover is provided with two insertion through holes corresponding to the mounting holes. The cover between the two insertion through holes forms an intermediate cover plate for fixing the signal module in the second mounting hole. The intermediate cover plate is provided with a plurality of signal pin through holes.

[0009] Furthermore, the end face of the second mounting hole is lower than the end face of the mounting hole, and the corresponding intermediate cover plate is lower than the cover body at both ends of the intermediate cover plate.

[0010] Furthermore, the surface of the insertion part is also fitted with a waterproof ring, and the end face of the cover abuts against the end face of the waterproof ring.

[0011] Furthermore, the cover body includes a cover plate body, and a side cover plate is formed by extending the side of the cover plate body. The side cover plate is provided with a snap-fit, and the insertion part is provided with a snap-fit ​​protrusion. When the cover body and the insertion part are engaged, the cover plate body presses on the end face of the insertion part, the side cover plate covers the surface of the insertion part, and the snap-fit ​​and snap-fit ​​protrusion cooperate to fix the cover plate and the insertion part.

[0012] Furthermore, the side cover plate is provided with an anti-reverse slot.

[0014] In summary, this utility model has the following beneficial effects:

[0015] This invention improves the structure of the electrical connector housing by designing a housing in which conductive components and wires are inserted from the front end and fixed by a cover. This effectively overcomes the problem of conductive components falling off due to easy failure of the rear cover in the prior art, thereby improving product reliability and production efficiency.

[0029] Figure 1 A schematic diagram of an electrical connector provided in an embodiment of this application;

[0030] In one embodiment, the electrical connector 5 includes a first housing 50 and a second housing 51 that are plugged into each other. The second housing 51 is the housing of an electrical connector, including a main plastic shell 1. The main plastic shell is provided with an insertion part 10, which is used to plug into the housing of another electrical connector. The insertion part extends into the interior of the housing of another electrical connector. The insertion part is provided with at least one mounting hole for installing a conductive component. The conductive component is used to realize the electrical connection of the electrical connector. After the conductive component is riveted with wires, it is inserted into the mounting hole from the front end of the insertion part. Then, the conductive component is fixed by the connection between the cover 2 and the insertion part.

[0031] By inserting the conductive component from the front end of the insertion part and securing it with the cover, the installation method of the conductive component is changed, and the risk of the conductive component falling off from the tail end is eliminated.

[0032] Figure 2 A perspective view of the housing of an electrical connector provided in an embodiment of this application;

[0033] In one embodiment, the housing of the electrical connector includes a main plastic shell 1, on which an insertion portion 10 is provided. At least one mounting hole 100 for mounting a conductive component 3 is provided on the end face of the insertion portion 10. The connector also includes a cover 2 connected to the insertion portion. The cover 2 is used to fix the conductive component 3 in the mounting hole. The cover 2 is provided with a plug-in through hole 20 corresponding to the mounting hole.

[0034] The housing of the electrical connector in this application embodiment can be a housing of an electrical connector with one conductive component, or it can be a housing of an electrical connector with two or more conductive components. Figure 2 A housing for an electrical connector with two conductive parts; combined Figure 2 The front and rear end are marked to illustrate this application. From the front end of the insertion part to the rear end of the main housing, there are mounting holes for installing conductive components. The conductive components are first riveted with wires on the outside, and then the wires and conductive components are sequentially inserted into the mounting holes from the front end. The conductive components are kept in the mounting holes, and then the cover is connected to the insertion part to fix the two. The cover around the insertion hole also limits the conductive components, thereby fixing the conductive components in the mounting holes. The insertion hole facilitates the conductive components to cooperate with the conductive body inside the housing of another electrical connector. This application changes the assembly method of the conductive components and the main housing, which facilitates installation and avoids the problem of conductive components falling off due to the easy breakage and detachment of the tail cover in the prior art.

[0035] In this embodiment, the end face of the insertion part 10 is provided with two mounting holes 100 for mounting conductive components. A second mounting hole 101 is provided on the end face of the insertion part 10 between the two mounting holes. The second mounting hole 101 is used to mount the signal module 4. The cover 2 is provided with two insertion through holes 20, which correspond to the mounting holes 100. An intermediate cover plate 21 is formed on the cover between the two insertion through holes. The intermediate cover plate 21 is used to fix the signal module in the second mounting hole. The intermediate cover plate is provided with a plurality of signal pin through holes 210. The housing of the electrical connector of this application is also suitable for electrical connectors with signal modules. The signal module is also assembled into the second mounting hole from the front end of the insertion part. Then, the signal module is axially fixed by the intermediate cover plate of the cover. The signal pin through holes facilitate the insertion of the signal module with the corresponding signal pin.

[0036] In this embodiment, the end face of the second mounting hole 101 is lower than the end face of the mounting hole, and the corresponding intermediate cover plate is lower than the cover body at both ends of the intermediate cover plate. By adopting the above structural design, the end face of the second mounting hole is lower than the end faces of the mounting holes on both sides, thereby obtaining a clearance space. The clearance space provides space for the setting of signal pins in the housing of another electrical connector, which is conducive to the miniaturization of the housing of the other electrical connector, and thus conducive to the miniaturization of the entire electrical connector.

[0037] In this embodiment, a waterproof ring 103 is also fitted on the surface of the insertion part 10. The end face of the cover abuts against the end face of the waterproof ring. Since the outer wall of the insertion part is smaller than the outer wall of the main housing, there is a step between the end of the insertion part and the main housing. When the cover is fixed to the front end of the insertion part, the edge of the cover is also higher than the outer wall of the insertion part, so there is also a step between the cover and the insertion part. The waterproof ring is set on the surface fitted on the insertion part. The steps at both ends are used to fix the waterproof ring axially, thereby eliminating the risk of the waterproof ring falling off.

[0038] In this embodiment, the cover 2 includes a cover plate body 200, with a side cover plate 201 extending from the side of the cover plate body. The side cover plate is provided with a snap-fit ​​202, and the insertion part 10 is provided with a snap-fit ​​protrusion 102. When the cover is engaged with the insertion part, the cover plate body 200 presses against the end face of the insertion part, the side cover plate 201 covers the surface of the insertion part 10, and the snap-fit ​​202 and the snap-fit ​​protrusion 102 cooperate to fix the cover plate and the insertion part. The cover is fixed to the insertion part by the snap-fit ​​on the side cover plate and the snap-fit ​​protrusion on the insertion part, thereby fixing the conductive components and signal modules with the cover plate.

[0039] In this embodiment of the application, the side cover plate 201 is provided with an anti-reverse slot 2011. The side cover plate is provided with at least one anti-reverse slot, which works in conjunction with the protruding rib on another electrically connected housing to achieve anti-reverse insertion. In this embodiment of the application, the side cover plate is provided with two anti-reverse slots, and the two anti-reverse slots are located on the same side of the cover.

[0040] In summary, this utility model has the following beneficial effects:

[0041] This invention improves the structure of the electrical connector housing by designing a housing in which conductive components and wires are inserted from the front end and fixed by a cover. This effectively overcomes the problem of conductive components falling off due to easy failure of the rear cover in the prior art, thereby improving product reliability and production efficiency.

[0042] Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
