Abstract
Description
Technical Field
[0001] This application relates to the field of aviation socket technology, and more specifically, to an aviation socket with dustproof function. Background Technology
[0002] Aviation sockets, also known as aviation plugs or connectors, are industrial-grade electrical connection components with high reliability and high protection performance. Due to their excellent stability, anti-interference and environmental adaptability, they are widely used in scenarios with high requirements for electrical connection reliability.
[0003] Traditional aviation sockets typically consist of a male (plug) and a female (socket), with the circuit being connected or disconnected by plugging and unplugging the male and female terminals. However, in practical use, to prevent dust from entering the male terminal when it is separated from the female terminal, a dust cover is usually installed on the outer end of the male terminal. However, most existing dust covers are made of plastic and are installed onto the male terminal by friction. Therefore, when removing the dust cover, the user needs to hold it and twist it repeatedly. With repeated plugging and unplugging, the dust cover will deform, reducing the friction between the dust cover and the outer wall of the male terminal, making it easy for the dust cover to fall off at the outer end of the male terminal, thus affecting its use. Utility Model Content
[0004] The purpose of this application is to provide an aviation socket with dustproof function to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this application provides the following technical solution:
[0006] An aviation socket with dustproof function includes a male terminal, a female terminal, and a locking component. The male terminal includes a male outer shell and a male plug inside the male outer shell. The male plug is installed inside the male outer shell through one end. The other end of the male outer shell is provided with a sealing component. An installation groove is provided on the outer side wall of the male outer shell along its circumference. The locking component is detachably installed in the installation groove. When the male terminal is plugged into the female terminal, the locking component locks the male terminal and the female terminal together. A dustproof cover is also provided on the outside of the male outer shell. The dustproof cover is sealed on the male plug by the locking component.
[0007] Preferably, the locking component includes a rotating cylinder fitted over the male housing, one end of the rotating cylinder having a retaining ring extending into the mounting groove, and the inner sidewall of the rotating cylinder having an internal thread at the other end;
[0008] The outer wall of the dust cover is provided with external threads that mate with the internal threads.
[0009] Preferably, the outer wall of the male ferrule is provided with a limiting groove along its axial direction, and the inner wall of the dust cover is provided with a limiting block that slides within the limiting groove.
[0010] Preferably, the inner wall of the dust cover is provided with a blocking round platform that mates with the male plug.
[0011] Preferably, the outer wall of the male housing is provided with a connecting groove at one end, which connects to the mounting groove. The connecting groove is arranged circumferentially around the male housing, and a plug ring is threaded into the connecting groove. The plug ring is used to confine the retaining ring part within the mounting groove.
[0012] Preferably, an annular groove is provided on the outer side wall of the male shell along its circumference, and a connecting ring is slidably provided in the annular groove. The connecting ring is connected to the dust cover by a connecting rope.
[0013] Preferably, the seal includes a clamping member fixedly connected to the other end of the male housing and a rotating member threadedly connected to the clamping member, wherein the rotating member is connected to the clamping member to clamp the clamping member.
[0014] Preferably, the clamping part includes an outer connecting part and a clamping part. The outer side of the clamping part is provided with a frustum surface along its circumference, and the outer side of the clamping part is provided with gap grooves at intervals along its circumference.
[0015] The rotating component includes a rotating sleeve, which has an inner connecting part and a pressing surface. When the inner connecting part is threaded onto the outer connecting part, it drives the pressing surface to press the frustum surface so that the clamping part clamps tightly.
[0016] Compared with the prior art, the beneficial effects of this application are:
[0017] 1. In this application, when the dust cover is placed on the male connector, it is fixed by a locking device. Compared with the existing dust covers that are installed by friction, this application uses a locking device to fix the dust cover, which can avoid the deformation of the dust cover caused by twisting, thereby improving its service life.
[0018] 2. In this application, by providing a blocking frustum inside the dust cover, the blocking frustum can extend into the corresponding first mounting hole when the locking member fixes the dust cover. The deformation of the blocking frustum can then press against the opening end of the first mounting hole, thereby better sealing the first mounting hole and improving its dustproof effect.

[0028] To further understand the content of this application, a detailed description of this application will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative and not intended to limit the scope of this application.
[0029] The following is in conjunction with the appendix Figures 1-7 This embodiment will be described in further detail.
[0030] like Figure 1 As shown, an aviation socket with dustproof function in this embodiment includes a male terminal 10, a female terminal 20 and a locking member 30. The locking member 30 is used to lock the male terminal 10 and the female terminal 20 when the male terminal 10 is inserted into the female terminal 20, so as to improve the anti-detachment effect of the two.
[0031] Combination Figures 2-5As shown, in this embodiment, the male end 10 includes a male outer shell 200 and a male insert 40 disposed within the male outer shell 200, and the female end 20 includes a female outer shell 21 and a female insert disposed within the female outer shell 21. The male insert 40 includes a male plastic core 220, which has a plurality of first mounting holes 221 for mounting the insertion member 420. One end of the male plastic core 220 is fixedly installed within the male outer shell 200, so that the other end of the male plastic core 220 with the first mounting holes 221 is located outside the male outer shell 200. The female insert includes a female plastic core. The inner part is provided with several second mounting holes for installing the pins 22. When the female plastic core is fixedly installed in the female housing 21, the pins 22 can be hidden in the female housing 21. Therefore, in actual use, the number of pins 22 corresponds to the number of sockets 420. When the other end of the male plastic core 220 is inserted into the female housing 21 to realize the male end 10 is inserted into the female end 20, the pins 22 are inserted into the corresponding first mounting holes 221 and electrically connected with the corresponding sockets 420, thereby realizing the electrical connection between the male end 10 and the female end 20.
[0032] The male connector 40 is installed inside the male housing 200 through one end. The other end of the male housing 200 is provided with a sealing element 50. The sealing element 50 is used to seal the wire and the other end of the male housing 200 when the wire is connected to the male connector 40, so as to improve the dustproof effect of the male terminal 10.
[0033] The outer side wall of the male housing 200 is provided with a mounting groove 201 along its circumference. The locking member 30 is detachably installed in the mounting groove 201. When the male end 10 is inserted into the female end 20, the locking member 30 locks the male end 10 and the female end 20 together. The male housing 200 is also provided with a dust cover 60, which is open at one end. The dust cover 60 covers the end of the male ferrule 40 located outside the male housing 200 through its opening, so as to block the first mounting hole 221. In actual use, the dust cover 60 is fixed to the male ferrule 40 by the locking member 30 to block it. Compared with the existing dust cover 60 which is installed by friction, the dust cover 60 is fixed by the locking member 30 in this embodiment, which can avoid the deformation of the dust cover 60 caused by twisting and thus improve its service life.
[0034] In this embodiment, the locking member 30 includes a rotating cylinder 210 fitted over the male housing 200. One end of the rotating cylinder 210 is provided with a retaining ring extending into the mounting groove 201. The retaining ring blocks the side walls at both ends of the mounting groove 201, which preferably prevents the rotating cylinder 210 from detaching from the male housing 200. The inner side wall of the rotating cylinder 210 and the other end are provided with internal threads, and the outer side wall of the female housing 21 is provided with external threads. Therefore, when the male end 10 is inserted into the female end 20, the rotating cylinder 210 slides and rotates along the mounting groove 201. By using the cooperation of the external and internal threads, the rotating cylinder 210 can be connected to the female housing 21 until the retaining ring abuts against the side wall of the mounting groove 201 near the female housing 21, so that the locking member 30 locks the inserted male end 10 and female end 20 to prevent them from falling off.
[0035] The outer wall of the dust cover 60 is provided with an external thread that mates with the internal thread on the inner wall of the rotating cylinder 210. Therefore, when the male end 10 is not inserted into the female end 20, the dust cover 60 is placed over the end of the male ferrule 40 located outside the male outer shell 200. The rotating cylinder 210 slides and rotates along the mounting groove 201. By utilizing the engagement of the external and internal threads, the rotating cylinder 210 can be connected to the outside of the dust cover 60 until the retaining ring abuts against the side wall of the mounting groove 201 near the dust cover 60. This allows the locking member 30 to fix the dust cover 60 to the male ferrule 40 through the threads. Compared to the existing method of installation using friction, the threaded connection in this embodiment is less likely to deform the dust cover 60, thereby improving the service life of the dust cover 60.
[0036] In this embodiment, in order to improve the sealing effect of the dust cover 60 on the male connector 40, wherein, combined with Figure 7 As shown, the inner wall of the dust cover 60 is provided with a blocking frustum 401 that mates with the male ferrule 40. The blocking frustum 401 is made of rubber material, and the number of blocking frustums 401 corresponds to the number of first mounting holes 221. When the dust cover 60 is fixed on the male ferrule 40, the blocking frustum 401 can extend into the corresponding first mounting hole 221. The deformation of the blocking frustum 401 then presses against the opening end of the first mounting hole 221, which can better seal the first mounting hole 221 and improve its dustproof effect.
[0037] Specifically, in order to align the blocking frustum 401 with the corresponding first mounting hole 221, in this embodiment, a limiting groove 222 is provided on the outer side wall of the male ferrule 40 along its axial direction, and a limiting block 241 is provided on the inner side wall of the dust cover 60, which slides within the limiting groove 222. When the limiting block 241 is aligned with the limiting groove 222 and the dust cover 60 is inserted into the outer end of the male ferrule 40, it can be ensured that the blocking frustum 401 extends into the corresponding first mounting hole 221 for actual use.
[0038] In this embodiment, in order to realize the removal and replacement of the locking member 30 in the mounting groove 201, combined with Figure 6 As shown, in this embodiment, a connecting groove 601 is provided on the outer side wall of the male housing 200 at one end, which connects to the mounting groove 201. The connecting groove 601 is arranged circumferentially along the male housing 200. External threads are provided on the side wall of the connecting groove 601, and a plugging ring 410 is connected to the internal thread of the connecting groove 601. Specifically, the plugging ring 410 is annular, and internal threads are provided on its inner side wall. By utilizing the cooperation of the external threads and the internal threads, the plugging ring 410 can be disassembled and installed in the connecting groove 601. When the plugging ring 410 is installed in the connecting groove 601, the plugging ring 410 is used to limit the retaining ring part to be located in the mounting groove 201, so as to realize the sliding installation of the locking member 30 in the mounting groove 201.
[0039] In this embodiment, to prevent the dust cover 60 from being lost, an annular groove 501 is provided on the outer side wall of the male outer shell 200 along its circumference. A connecting ring 230 is slidably provided in the annular groove 501. The connecting ring 230 is connected to the dust cover 60 by a connecting rope 231. The other end of the connecting rope 231 is rotatably connected to the outer end of the dust cover 60 through the annular ring. Thus, the dust cover 60 is connected to the outside of the male end 10 to prevent it from being lost.
[0040] In this embodiment, the male outer shell 200 is made of plastic to ensure the corrosion resistance of the male end 10; the sealing member 50 includes a clamping member integrally formed on the other end of the male outer shell 200 and a rotating member threadedly connected to the clamping member. When the rotating member is connected to the clamping member, the clamping member is clamped.
[0041] In actual use, the wire passes through the rotating member and the clamping member in sequence and extends into the male housing 200. The wire core is then soldered to the corresponding socket 420. When the male socket 40 is fixedly installed in the male housing 200, the electrical connection between the wire and the male terminal 10 can be achieved. In order to improve the sealing effect at the wire insertion point, when the rotating member is connected to the clamping member, the clamping member clamps the wire, thereby sealing the connection and improving its dustproof effect.
[0042] Specifically, the clamping member includes an outer connecting part 511 and a clamping part 512. The outer side wall of the outer connecting part 511 is provided with external threads, and the outer side of the clamping part 512 is provided with a frustum surface along its circumference. The outer side of the clamping part 512 is provided with gap grooves at intervals along its circumference, so that the clamping part 512 can clamp inward.
[0043] The rotating component includes a rotating sleeve 520, which has an inner connecting part and a pressing surface. The inner connecting part is provided with an internal thread. By using the cooperation of the internal thread and the external thread, the rotating component is threadedly connected to the clamping component. When the inner connecting part is threadedly connected to the outer connecting part 511, it drives the pressing surface to press the frustum surface so that the clamping part 512 clamps inward to the outside of the wire.
[0044] In order to improve the sealing effect when clamped, the outer sleeve of the wire is provided with a sealing ring located at the clamping part 512.
[0045] In actual use, in order to facilitate the user to rotate the rotating sleeve 520, a rotating part is provided on the outer side wall of the rotating sleeve 520. The rotating part is a polygon on the outer side wall of the rotating sleeve 520 so that the user can hold and rotate it and avoid slipping.
[0046] In summary, the above description is only a preferred embodiment of this application. All equivalent changes and modifications made within the scope of this application should be covered by this application.
