Description

Technical Field

[0001] The present application belongs to the field of cable design technology, and specifically relates to a cable and a camera. Background Art

[0002] Electronic devices usually consist of a device body and cables. The cables contain core wires such as power and network wires. The cables need to pass through the outer casing of the device body and electrically connect to the circuits inside the device body, thereby connecting the electronic device to external power supplies, networks, and other devices. In addition, in actual applications, it is necessary to ensure that the connection between the cable and the outer casing is reliably sealed to prevent impurities such as water stains from entering the device body.

[0003] Currently, the most common sealing connection method between cables and housings is to seal and fix them through glue injection. Specifically, the cable and housing are first assembled and then glue injection is performed. The glue is then placed in a high-temperature environment to cure. However, the glue injection and curing time is long, resulting in low cable assembly efficiency, which in turn affects the overall assembly efficiency of the electronic device. Utility Model Content

It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0019] The cable and camera provided in the embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0020] like Figures 1 to 5 As shown, an embodiment of the present application discloses a cable. Optionally, the cable includes a wire core 130 and an insulating layer 140 . The insulating layer 140 wraps the wire core 130 to protect the wire core 130 .

[0021] An annular wire stopper 120 is provided on the outer surface of the cable. Specifically, an annular wire stopper 120 is provided on the outer surface of the insulating layer 140, that is, the annular wire stopper 120 is an insulating structure, and the annular wire stopper 120 and the insulating layer 140 are an integral structure. The first end 110 of the cable is used to pass through the housing 200 of the electronic device and extend into the accommodating cavity of the housing 200. Optionally, the first end 110 of the cable can be electrically connected to the circuit board in the accommodating cavity of the housing 200, so as to supply power to the electronic device, transmit electrical signals, etc. The annular wire stopper 120 is used to be plugged into the plug hole 210 of the housing 200. The annular wire stopper 120 and the plug hole 210 are interference fit so that the two are sealed together, thereby preventing impurities such as water stains and dust in the external environment from entering the accommodating cavity of the housing 200, so as to protect the structure set in the accommodating cavity.

[0022] In the embodiment of the present application, the annular wire stopper 120 of the cable is plugged into and mated with the insertion hole 210 of the electronic device housing 200. The annular wire stopper 120 and the insertion hole 210 have an interference fit, resulting in a sealed fit. This eliminates the need for glue sealing and fixation, saving time for glue filling and curing, thereby improving cable assembly efficiency. Therefore, the embodiment of the present application can solve the current problem of low cable assembly efficiency.

[0023] It should be noted that the sealing cooperation between the annular cable stop 120 and the plug hole 210 of the housing 200 in the above solution is mainly used in products with a waterproof standard of IPX5 or below.

[0024] Optionally, the outer peripheral surface of the annular wire stopper 120 can be sealed with the inner wall of the plug-in hole 210 by a sealing ring; or; in an optional embodiment, in the plug-in direction of the annular wire stopper 120, the annular wire stopper 120 includes a first part 121 and a second part 122 that are connected, and the cross-sectional area of ​​the first part 121 is larger than the cross-sectional area of ​​the second part 122, and a first sealing end face 123 is formed at the connection between the first part 121 and the second part 122, that is, the outer peripheral surface of the annular wire stopper 120 is a stepped surface in the plug-in direction of the annular wire stopper 120, and the first sealing end face 123 is used to seal with the second sealing end face 211 in the plug-in hole 210, and the two are limitedly matched along the plug-in direction of the annular wire stopper 120. During the installation of the annular wire stopper 120, when the first sealing end face 123 and the second sealing end face 211 are limitedly engaged, the annular wire stopper 120 will be prevented from continuing to be inserted relative to the plug-in hole 210, thereby avoiding the plug-in distance of the annular wire stopper 120 being too large, thereby protecting the outer shell 200; and, when the first sealing end face 123 and the second sealing end face 211 are limitedly engaged, the two are also sealed together, thereby preventing impurities between the outer peripheral surface of the first part 121 and the inner wall of the plug-in hole 210 from entering between the outer peripheral surface of the second part 121 and the inner wall of the plug-in hole 210.

[0025] Optionally, at least one of the outer circumferential surface of the first part 121 and the outer circumferential surface of the second part 122 is used to seal with the inner surface of the plug hole 210. Specifically, only the outer circumferential surface of the first part 121 can be used to seal with the inner surface of the plug hole 210, thereby preventing impurities in the external environment from entering between the outer circumferential surface of the first part 121 and the inner wall of the plug hole 210; or only the outer circumferential surface of the second part 122 can be used to seal with the inner surface of the plug hole 210, thereby preventing impurities between the first sealing end face 123 and the second sealing end face 211 from entering between the outer circumferential surface of the first part 121 and the inner wall of the plug hole 210; or both the outer circumferential surface of the first part 121 and the outer circumferential surface of the second part 122 can be used to seal with the inner surface of the plug hole 210 (in this case, the outer circumferential surface of the first part 121 and the outer circumferential surface of the second part 122 are sealed with different parts of the inner surface of the plug hole 210), thereby forming a multi-channel sealing structure for sealing. This solution improves the sealing effect between the annular wire stopper 120 and the plug hole 210 by sealing the outer circumferential surface of the first part 121, the outer circumferential surface of the second part 122 and the first sealing end surface 123 with the inner surface of the plug hole 210 respectively.

[0026] In a further optional embodiment, at least one of the outer peripheral surface of the first part 121, the outer peripheral surface of the second part 122 and the first sealing end surface 123 is provided with an annular sealing protrusion 122a, and the annular sealing protrusion 122a is used to interference fit with the inner surface of the plug-in hole 210 so that the two are sealed together, thereby further improving the sealing between the annular wire stop 120 and the plug-in hole 210.

[0027] Optionally, the number of annular sealing protrusions 122a may be one; the number of annular sealing protrusions 122a may also be at least two. The annular sealing protrusions 122a located on the outer circumferential surface of the first portion 121 and the outer circumferential surface of the second portion 122 are sequentially spaced apart along the insertion direction of the annular wire stopper 120, and the annular sealing protrusions 122a located on the first sealing end surface 123 are sequentially spaced apart along the radial direction of the first sealing end surface 123. By providing multiple annular sealing protrusions 122a, the sealing between the annular wire stopper 120 and the insertion hole 210 is further improved.

[0028] Optionally, in the plug-in direction of the annular wire stopper 120, the cross-sectional areas of the first part 121 at various locations may be equal; or, in other embodiments, in the plug-in direction of the annular wire stopper 120, the cross-sectional area of ​​the first part 121 gradually decreases, that is, the first part 121 has a conical structure. During the plug-in process of the annular wire stopper 120, the end with the smaller cross-sectional area of ​​the first part 121 is first inserted into the plug-in hole 210. At this time, the plug-in hole 210 provides a guiding function for the first part 121, thereby improving the assembly efficiency of the annular wire stopper 120.

[0029] Optionally, in the plug-in direction of the annular wire stopper 120, the cross-sectional areas of the second part 122 at various locations may be equal; or, in other embodiments, in the plug-in direction of the annular wire stopper 120, the cross-sectional area of ​​the second part 122 gradually decreases, that is, the second part 122 has a conical structure. During the plug-in process of the annular wire stopper 120, the end of the second part 122 with a smaller cross-sectional area is first inserted into the plug-in hole 210. At this time, the plug-in hole 210 provides a guiding function for the second part 122, thereby improving the assembly efficiency of the annular wire stopper 120.

[0030] In another optional embodiment, the annular wire stopper 120 can be positioned and fixed to the inner wall of the insertion hole 210 by friction; alternatively, the surface of the annular wire stopper 120 facing away from the first end 110 is an annular mating surface 124, which is configured to snap-fit ​​with a deformable buckle 220 at the insertion interface of the insertion hole 210 along the insertion direction of the annular wire stopper 120. When the annular wire stopper 120 is inserted into the insertion hole 210, the deformable buckle 220 snaps into engagement with the annular mating surface 124, thereby securing the annular wire stopper 120. This improves the insertion security and stability of the annular wire stopper 120 and prevents the annular wire stopper 120 from falling out of the insertion hole 210 during use of the electronic device.

[0031] Optionally, the annular mating surface 124 can be an annular plane; or, in other optional embodiments, the annular mating surface 124 is an annular inclined surface, the distance between the inner edge of the annular mating surface 124 and the plane where the plug interface of the plug hole 210 is located is a first distance, and the distance between the outer edge of the annular mating surface 124 and the plane where the plug interface of the plug hole 210 is located is a second distance, and the first distance is greater than the second distance, that is, in the plugging direction of the annular wire stop 120, the distance between the annular mating surface 124 and the center axis of the cable gradually decreases, and the angle α between the annular mating surface 124 and the plane where the plug interface of the plug hole 210 is located is greater than 0°. Specifically, when the deformable buckle 220 is snap-fitted with the annular mating surface 124, since the annular mating surface 124 is an annular inclined surface, the angle between the contact surface of the deformable buckle 220 and the annular mating surface 124 and the inner surface of the plug-in hole 210 is an acute angle, and the fitting stability between the two is better, which is conducive to improving the stability of the snap-fit ​​between the deformable buckle 220 and the annular mating surface 124, so as to further improve the plug-in firmness and stability of the annular wire stop 120.

[0032] It should be noted that the annular wire stopper 120 disclosed in the embodiment of the present application eliminates the high-precision requirements brought about by the coupling of the fixed structure and the sealing structure in the traditional cable structure, so that the tolerance of the annular wire stopper 120 to dimensional deviation is greatly increased, thereby improving the reliability of the sealing structure under the existing processing precision.

[0033] Based on the cable disclosed in the embodiment of the present application, the embodiment of the present application also discloses a camera, which includes a housing 200, a circuit board and the cable 100 described in any of the above embodiments. The circuit board is arranged in the accommodating cavity of the housing 200, and the housing 200 is provided with a plug hole 210. The first end 110 of the cable passes through the plug hole 210 to be electrically connected to the circuit board, and the annular wire stopper 120 is plugged into the plug hole 210, and the annular wire stopper 120 is interference fit with the plug hole 210 so that the two are sealed.

[0034] In an optional embodiment, in the plug-in direction of the annular wire stopper 120, the annular wire stopper 120 includes a connected first part 121 and a second part 122, the cross-sectional area of ​​the first part 121 is larger than the cross-sectional area of ​​the second part 122, and a first sealing end face 123 is formed at the connection between the first part 121 and the second part 122. In the plug-in direction of the annular wire stopper 120, the plug-in hole 210 includes a connected first hole section 213 and a second hole section 214, the cross-sectional area of ​​the first hole section 213 is larger than the cross-sectional area of ​​the second hole section 214, and a second sealing end face 211 is formed at the connection between the first hole section 213 and the second hole section 214. The second sealing end face 211 is sealed with the first sealing end face 123, and the two are limitedly matched along the plug-in direction of the annular wire stopper 120. Specifically, during the installation of the annular wire stopper 120, when the first sealing end face 123 and the second sealing end face 211 are limited in position, the annular wire stopper 120 will be prevented from continuing to be inserted relative to the plug-in hole 210, thereby avoiding the plug-in distance of the annular wire stopper 120 being too large to protect the outer shell 200; and, when the first sealing end face 123 and the second sealing end face 211 are limited in position, the two are also sealed together, thereby preventing impurities between the outer peripheral surface of the first part 121 and the inner wall of the plug-in hole 210 from entering between the outer peripheral surface of the second part 121 and the inner wall of the plug-in hole 210.

[0035] Optionally, the outer peripheral surface of the first part 121 is sealed with the inner surface of the first hole section 213, and the outer peripheral surface of the second part 122 is sealed with the inner surface of the second hole section 214. At this time, a multi-channel sealing structure is formed between the outer peripheral surface of the annular wire stopper 120 and the inner surface of the plug-in hole 210, thereby improving the sealing effect between the annular wire stopper 120 and the plug-in hole 210.

[0036] Optionally, the outer peripheral surface of the annular wire stopper 120 and the inner surface of the plug-in hole 210 can be fixed by friction; or, in another optional embodiment, the side of the annular wire stopper 120 facing away from the first end 110 is an annular mating surface 124, and the plug-in interface of the plug-in hole 210 is provided with at least two deformable buckles 220 arranged at circumferential intervals along the plug-in hole 210, and each deformable buckle 220 is located in the plug-in hole 210, and each deformable buckle 220 is snap-fitted with the annular mating surface 124 along the plug-in direction of the annular wire stopper 120. During the process of plugging the annular wire stopper 120, each deformable buckle 220 is deformed so that the annular wire stopper 120 is plugged into the plug-in hole 210; when the annular wire stopper 120 is plugged into the plug-in hole 210, each deformable buckle 220 recovers its deformation, and each deformable buckle 220 is snap-fitted with the annular mating surface 124 along the plug-in direction of the annular wire stopper 120, thereby fixing the annular wire stopper 120 to the plug-in hole 210, so as to improve the plug-in firmness and stability of the annular wire stopper 120, and prevent the annular wire stopper 120 from falling out of the plug-in hole 210 during the use of the electronic device.

[0037] In a further optional embodiment, the housing 200 is provided with an annular glue dispensing groove 230, which is arranged around the plug hole 210. The inner wall of the plug hole 210 is provided with an avoidance opening 215. The avoidance opening 215 and the deformation buckle 220 are arranged at intervals along the circumference of the plug hole 210, and the annular glue dispensing groove 230 is connected to the plug hole 210 through the avoidance opening 215. When the annular wire stopper 120 is inserted into the plug hole 210, glue can be added to the annular glue dispensing groove 230. At this time, the glue in the annular glue dispensing groove 230 flows into the plug hole 210. After the annular glue dispensing groove 230 is filled with glue, the glue is cured to seal the assembly gap between the annular wire stopper 120 and the plug hole 210, thereby improving the sealing of the accommodating cavity of the housing 200 and improving the connection firmness and stability between the annular wire stopper 120 and the inner wall of the plug hole 210. Of course, the annular glue dispensing groove 230 may not be provided, and glue filling and sealing may not be performed.

[0038] It should be noted that, in the above embodiment, based on the interference fit between the annular wire stopper 120 and the plug-in hole 210 of the housing 200 to achieve sealing, the sealing between the annular wire stopper 120 and the inner wall of the plug-in hole 210 is improved by means of glue sealing. Therefore, this solution can be applied to products with higher requirements for waterproof sealing, such as products with a waterproof standard of IPX6 or above.

[0039] Optionally, the number of the avoidance opening 215 can be one; or, the number of the avoidance opening 215 is at least two, and each avoidance opening 215 is arranged at intervals along the circumference of the plug hole 210, thereby improving the efficiency of the glue in the annular glue dispensing groove 230 flowing into the plug hole 210.

[0040] Alternatively, the annular glue dispensing groove 230 may have a circular structure, a square structure, or the like; or, in other embodiments, the dimension of the annular glue dispensing groove 230 in the first direction is greater than the dimension of the annular glue dispensing groove 230 in the second direction, wherein the first direction is perpendicular to the second direction, and both the first direction and the second direction are perpendicular to the insertion direction of the annular wire stop 120. The annular glue dispensing groove 230 is a strip-shaped structure, and the insertion hole 210 is located in the center of the annular glue dispensing groove 230, so that the glue in the annular glue dispensing groove 230 flows evenly into the insertion hole 210, avoiding the existence of a glue blind spot in the insertion hole 210. Optionally, the opening direction of the avoidance opening 215 is parallel to the second direction, that is, the avoidance opening 215 faces the side wall of the annular glue dispensing groove 230 in its width direction. When the annular glue dispensing groove 230 is filled with glue and needs to be cured, the area where more glue is collected in the annular glue dispensing groove 230 is located on the two opposite sides of the plug-in hole 210 in the length direction of the annular glue dispensing groove 230. At this time, the area is staggered with the avoidance opening 215, which is conducive to speeding up the fixation of the glue, thereby improving the assembly efficiency of the annular wire stop 120.

[0041] Optionally, in the insertion direction of the annular wire stopper 120, the deformable buckle 220 has a snapping plane 221 and a guiding inclined surface 222 disposed in opposite directions. The annular wire stopper 120 can be guided and matched with the guiding inclined surface 222, so that the annular mating surface 124 snaps and fits with the snapping plane 221 along the insertion direction of the annular wire stopper 120. During the process of inserting the annular wire stopper 120 into the insertion hole 210, the edge of the outer peripheral surface of the annular wire stopper 120 near the annular mating surface 124 first guides and fits with the guiding inclined surface 222, so that the annular wire stopper 120 is smoothly inserted into the insertion hole 210, so that the annular mating surface 124 snaps and fits with the snapping plane 221 along the insertion direction of the annular wire stopper 120. Therefore, the provision of the guiding inclined surface 222 is conducive to improving the insertion efficiency of the annular wire stopper 120.

[0042] Optionally, the annular mating surface 124 is arranged to fit the clamping plane 221 . In this case, the contact area between the two is larger, which is conducive to improving the clamping stability between the deformable buckle 220 and the annular wire stopper 120 .

[0043] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
