[0015] The locking portion partially surrounds the central hole segment, and in the circumferential direction of the central hole segment, the locking portion and the sub-hole segment are spaced apart from each other, so that the cable sleeve member can rotate relative to the cable mounting member after passing through the sub-hole segment, and when the cable sleeve member is rotated to the locking position, the first limiting member is in abutment with the first side wall, and the second limiting member is in abutment with the second side wall;

[0017] In one embodiment, a portion of the circumferential side wall of the cable sleeve protrudes to form a limiting ridge;
[0018] The side wall of the central hole section is spaced apart from the circumferential side wall of the cable sleeve member, forming a first gap and a second gap that are connected in sequence, and when the cable sleeve member passes through the sub-hole section, the limiting protrusion is located in the first gap, and when the cable sleeve member is in the locking position, the limiting protrusion is located in the second gap;

[0052] The present application provides a cable connection structure.
[0053] In the present application, the cable connection structure includes a cable mounting member 10 , a cable sleeve member 21 , a first limiting member 22 and a second limiting member 23 .
[0054] The cable mounting member 10 has a first side wall 11 and a second side wall 12 facing each other, the second side wall 12 is provided with a through hole 13, and the through hole 13 passes through the first side wall 11; the cable sleeve member 21 is provided with a through hole 13 from the second side wall 12, and the cable sleeve member 21 is used to be sleeved on the outside of the cable 30; the first limit member 22 and the second limit member 23 are fixedly arranged on the circumferential side walls of the cable sleeve member 21, and in the axial direction of the cable sleeve member 21, the first limit member 22 and the second limit member 23 are spaced apart from each other so that the first limit member 22 and the second limit member 23 are located on different sides of the cable mounting member 10; wherein the first limit member 22 is abutted against the first side wall 11, and the second limit member is abutted against the second side wall 12 to lock the cable sleeve member 21 and the cable mounting member 10.
[0055] Specifically, see Figures 1 to 4 The cable mounting part 10 can be constructed as a part of the junction box shell of an electronic device such as a camera, or as a part of the shell of the main body of an electronic device such as a camera. This embodiment is specifically described by taking the example of the cable mounting part 10 being constructed as a part of the shell, that is, being constructed as a thin-walled part. At this time, one side wall of the cable mounting part 10 is the first side wall 11, and the other side wall is the second side wall 12. In this embodiment, the first side wall 11 faces the inside of the electronic device, while the second side wall 12 faces the outside of the electronic device. The cable mounting part 10 is provided with a through hole 13, which connects the first side wall 11 and the second side wall 12 for allowing the cable 30 to pass through, so that the cable 30 can enter the shell of the electronic device from the outside to serve as an electrical energy and signal transmission medium for electronic devices such as cameras.
[0056] The cable sleeve 21 is constructed as a hollow tube with both ends open, so that the cable sleeve 21 can be sleeved over the cable 30. In some embodiments, to facilitate the passage of the cable 30, the central axis of the cable sleeve 21 is a straight line, that is, it can be constructed as a straight sleeve. In order to improve the sealing performance of the electronic device, the cable sleeve 21 and the cable 30 can be interference-fitted. The length of the cable sleeve 21 is longer than the length of the through hole 13 on the cable mounting member 10. Therefore, when the cable sleeve 21 penetrates the through hole 13 from the second side wall 12, one end of the cable sleeve 21 is exposed to the outside, while the other end extends into the housing of the electronic device.
[0057] A first limiting member 22 and a second limiting member 23 are fixedly provided on the circumferential side wall of the cable sleeve member 21, and the first limiting member 22 and the second limiting member 23 are spaced apart in the axial direction of the cable sleeve member 21, so that after the cable sleeve member 21 is penetrated by the through hole 13, the first limiting member 22 is located on the end of the cable sleeve member 21 extending into the electronic device housing, and the second limiting member 23 is located on the end of the cable sleeve member 21 exposed to the outside, that is, the first limiting member 22 and the second limiting member 23 are located on opposite sides of the cable mounting member 10.
[0058] In some specific embodiments, the first stopper 22 and the second stopper 23 can be fixed to the circumferential side wall of the cable sleeve 21 by welding, bonding, or screw fastening. Alternatively, in other embodiments, the first stopper 22, the cable sleeve 21, and the second stopper 23 are constructed as an integrally formed part. In this case, the number of structural components of the entire cable connection structure can be reduced. In addition, the overall size of the first stopper 22, the cable sleeve 21, and the second stopper 23 can be constructed to be smaller, thereby reducing the overall size of the cable connection structure and, in turn, reducing the space occupied by the cable connection structure within the electronic device housing.
[0059] The cable sleeve 21 can rotate in the through hole 13, that is, the cable sleeve 21 has a release position and a locking position relative to the cable mounting member 10. Figures 1 to 3 When the cable sleeve 21 is in the released position, the first limiting member 22 and the cable sleeve 21 can pass through the through hole 13 and return to the outside of the electronic device housing. That is, when the cable sleeve 21 passes through the through hole 13 on the second side wall 12, it is in the released position. At this time, the first limiting member 22 is separated from the first side wall 11, or the second limiting member 23 is separated from the second side wall 12, or the first limiting member 22 is separated from the first side wall 11 and the second limiting member 23 is separated from the second side wall 12, so that the first limiting member 22 and the second limiting member 23 cannot complete the limitation of the cable sleeve 21, and the cable sleeve 21 can still rotate freely. Then, please refer to Figure 3 and Figure 4The cable sleeve member 21 can be rotated around the central axis of the through hole 13 by a preset angle to a locking position. At this time, the first limiting member 22 is abutted against the first side wall 11, and the second limiting member 23 is abutted against the second side wall 12, so that the first limiting member 22 and the second limiting member 23 respectively squeeze the cable mounting member 10 from both sides of the cable mounting member 10 to prevent relative displacement between the two, so as to lock the cable sleeve member 21 and the cable mounting member 10.
[0060] It is understandable that since the first limiting member 22 and the second limiting member 23 respectively squeeze the cable mounting member 10 from both sides to complete the limiting locking, the first limiting member 22 and the second limiting member 23 can be arranged opposite each other or staggered, and this embodiment does not limit this. Figure 1 In one embodiment, the first stopper 22 and the second stopper 23 are arranged opposite each other to reduce the difficulty of injection molding and make the force on the cable sleeve more stable. It should be noted that the following description uses the example of the first stopper 22 and the second stopper 23 being arranged opposite each other.
[0061] As is readily understood, in existing cable connection structures, cable 30 is secured to the camera housing by screwing screws from the inside out. However, this method increases the thickness of the cable connection structure, thereby affecting the camera's external dimensions. Alternatively, some camera products still utilize glue fixation. While this can reduce the overall size of the cable connection structure by reducing the height of the glue structure, the glued portion of the cable inside the camera becomes rigid and unbendable after application. To accommodate this rigid portion, sufficient space must still be reserved within the housing, limiting this approach's potential for size reduction.
[0062] In the present embodiment, only one end portion of the first limiting member 22 and the cable sleeve member 21 extends into the first side wall 11 side of the cable mounting member 10, that is, the interior of the shell, and since the present embodiment adopts a fixing method in which the first limiting member 22 and the second limiting member 23 are clamped from both sides of the cable mounting member 10, the connection strength is mainly affected by the matching area. When the dimension in the cable length direction is small, the required connection strength can be met, thereby avoiding occupying too much space inside the electronic device, so that the external dimensions of electronic devices such as cameras can be further reduced.
[0063] In one embodiment, a portion of the first side wall 11 protrudes to form a first protruding portion 111 ; wherein the first limiting member 22 abuts against and engages with the first protruding portion 111 .
[0064] Specifically, see Figure 5The first protrusion 111 is formed by a portion of the first side wall 11 protruding from the cable sleeve 21 when the cable mounting member 10 is in the locked position. The first protrusion 111 is thicker than other portions of the first side wall 11. Therefore, when the cable sleeve 21 is not rotated to the locked position, the first and second limiting members 22 and 23 do not engage with the cable mounting member 10 at the same time. Only when the cable sleeve 21 is rotated to the locked position does the first limiting member 22 abut against the first protrusion 111, thereby making it easier for the first and second limiting members 22 and 23 to be clamped on both sides of the cable mounting member 10.
[0065] It can be seen that in this embodiment, by forming the first protrusion 111 on the first side wall 11 to abut against the first limit member 22, not only can the thickness of the matching portion on the cable mounting member 10 be increased and the connection strength be improved, but also the cable connection structure can be rotated a certain angle after passing through the through hole 13 during installation until the first limit member 22 and the first protrusion 111 are matched, which makes installation more convenient and quick.
[0066] In one embodiment, the first protrusion 111 has a transition slope 1111 , and a side of the first protrusion 111 away from the first side wall 11 is connected to the first side wall 11 via the transition slope 1111 .
[0067] Specifically, see Figure 5 As an option in this embodiment, the first protrusion 111 can be configured in a wedge or trapezoidal shape, with the waist sidewall serving as a transition slope 1111 connecting the upper surface of the first protrusion 111 and the first sidewall 11. In this case, during the rotation of the first position limiter 22 from the released position to the locked position, the transition slope 1111 can provide guidance. Connecting the first sidewall 11 and the first protrusion 111 via the transition slope 1111 facilitates a more convenient, quick, and smooth rotation of the first position limiter 22 to the locked position. In this case, the first position limiter can engage with the transition slope 1111, or it can engage with the upper surface of the first protrusion 111 after passing through the transition slope 1111. This is not a limitation in this embodiment.
[0068] Alternatively, see Figure 6 and Figure 9As another option of this embodiment, a portion of the first side wall 11 protrudes to form a first protrusion 111 and a locking portion 113, and the locking portion 113 and the first protrusion 111 are opposite to each other and spaced apart to form a locking slot 112; a portion of the first limiting member 22 extends into the locking slot 112, and the side wall surface of the first limiting member 22 facing the first side wall 11 is spaced apart from the bottom wall of the locking slot 112; wherein, the side of the first limiting member 22 close to the first protrusion 111 is abutted against the side of the first protrusion 111 away from the second side wall 12; and / or the side of the first limiting member 22 close to the locking portion 113 is abutted against the side of the locking portion 113 away from the second side wall 12.
[0069] Specifically, see Figure 6 、 Figures 9 to 11 Corresponding to the locked position of the cable sleeve 21 on the cable mounting member 10, the first side wall 11 is formed with a locking portion 113 and a first protrusion 111, which are opposite and spaced apart from each other, forming a locking slot 112 therebetween. When the cable sleeve 21 moves to the locked position, a portion of the first limiting member 22 enters the locking slot 112, preventing the first limiting member 22 from rotating back to the released position.
[0070] The first stopper 22 enters the locking slot 112, and the bottom end surface of the first stopper 22 is spaced apart from the bottom wall of the locking slot 112, that is, the first sidewall 11 between the locking portion 113 and the first protrusion 111. As a result, the bottom end surface of the first stopper 22 is not subjected to force, but the force is mainly applied to the portion of the first stopper 22 in contact with the locking portion 113 and the portion of the first stopper 22 in contact with the transition slope 1111. This arrangement also prevents the bottom end surface of the first stopper 22 from deforming in contact with the first sidewall and generating elastic force that could cause the first stopper 22 to pop out of the locking slot 112.
[0071] At this time, the part of the first limit member 22 that contacts the locking portion 113 is squeezed and deformed, that is, the side of the first limit member 22 close to the locking portion 113 is abutted and matched with the side of the locking portion 113 away from the second side wall 12, and the part of the first limit member 22 that contacts the transition inclined surface 1111 is also squeezed and deformed, that is, the side of the first limit member 22 close to the first protrusion 111 is abutted and matched with the side of the first protrusion 111 away from the second side wall 12, so that the movement of the left and right sides of the locking slot 112 is respectively constrained by the locking portion 113 and the first protrusion 111, that is, the first limit member 22 is spaced apart from the first side wall 11 between the locking portion 113 and the first protrusion 111, so that the first limit member 22 and the second limit member 23 are respectively pressed from both sides of the cable mounting member 10, thereby the axial movement of the first limit member 22 in the cable sleeve member 21 is also constrained.
[0072] In addition, since the transition slope 1111 is arranged toward the locking portion 113, the first limiting member 22 can be pushed toward the direction of the locking portion 113, and the side wall of the locking portion 113 toward the first protrusion 111 can be perpendicular to the first side wall 11, that is, a vertical plane is formed, and the left side wall of the first limiting member 22 cooperates with the vertical plane. Since the vertical plane is difficult to slide, the difficulty of disassembling the cable connection structure can be increased, and the reliability of the cable connection structure can be further improved.
[0073] In one embodiment, the through hole 13 includes a central hole segment 131 and a sub-hole segment 132 that are connected to each other. The sub-hole segment 132 is arranged on one side of the central hole segment 131 and extends in a direction away from the central hole segment 131. The sub-hole segment 132 is for the first limiting member 22 to pass through, and the central hole segment 131 is for the cable sleeve member 21 to pass through.
[0074] Specifically, see Figure 6 The central hole section 131 can be constructed as a circular hole, the inner diameter of which is not less than the outer diameter of the cable sleeve 21, and the shape of the sub-hole section 132 matches the orthographic projection of the first stopper 22 on the plane where the first side wall 11 is located, so that the overall shape of the through hole 13 matches the end surface projection of the first stopper 22 and the cable sleeve 21. Figure 1 During installation, the first limiting member 22 can be aligned with the sub-hole segment 132, and the cable sleeve member 21 can be aligned with the center hole segment 131. Then, the cable sleeve member 21 can be pushed axially along the through hole 13, so that the cable sleeve member 21 passes through the center hole segment 131 and drives the first limiting member 22 to pass through the sub-hole segment 132, so as to improve the perforation efficiency of the cable sleeve member 21 and further improve the cable installation efficiency.
[0075] In one embodiment, the locking portion 113 partially surrounds the central hole section 131. The locking portion 113 and the sub-hole section 132 are spaced apart from each other circumferentially around the central hole section 131. This allows the cable sleeve 21 to rotate relative to the cable mounting member after passing through the sub-hole section 132. When the cable sleeve 21 is rotated to the locked position, the first stopper 22 abuts against the first side wall 11, and the second stopper 23 abuts against the second side wall 12.
[0076] The locking portion 113 has a guide slope 1131 facing away from the second side wall 12. The guide slope 1131 extends obliquely in the direction from the locking portion 113 to the sub-hole segment 132 along the direction close to the second side wall 12, and is smoothly connected to the first side wall 11 between the hole side walls of the sub-hole segment 1131.
[0077] Specifically, the locking portion 113 and the sub-hole segment 132 are spaced apart from each other in the circumferential direction of the central hole segment 131. Thus, on the plane of the first side wall 11, an angle is formed between the locking portion 113 and the sub-hole segment 132. Thus, in this embodiment, after the cable sleeve 21 and the first limiting member 22 are passed through the through hole 13 as a whole in one step, the cable sleeve 21 can be rotated around the central hole segment 131 by the angle, which makes installation more convenient and quick. Figure 3 and Figure 4 The angle between the locking portion 113 and the sub-hole segment 132 is 90°, that is, the angle between the release position and the locking position is 90°, so that the cable sleeve member 21 can be rotated 90° around the central hole segment 131.
[0078] At this time, see Figure 6 The first side wall 11 at the center hole section 131 is lifted upward to form an arc-shaped protrusion. The radial inner side wall of the arc-shaped protrusion is an arc-shaped surface. The center of the arc-shaped surface is located on the central axis of the center hole section 131. The arc-shaped protrusion is the locking portion 113. The upper surface of the locking portion 113 extends obliquely in the direction close to the second side wall 12, that is, it is tilted downward to form a guide slope 1131. The lower end of the guide slope 1131 is connected to the hole wall of the sub-hole section 132, so that during the rotation of the first limiting member 22, the first limiting member 22 contacts the guide slope 1131. Then, during the rotation, the first limiting member 22 is continuously lifted by the guide slope 1131, forcing the first limiting member 22 to drive the second limiting member 23 to move through the cable sleeve member 21, so that the gap between the second limiting member 23 and the second side wall 12 is continuously reduced until the two are pressed together. During this process, the first limiting member 22 continues to rotate until the first limiting member 22 enters the locking slot 112 .
[0079] It can be seen that in this embodiment, since the angle of the guiding inclined surface 1131 is relatively gentle, the process of rotating the cable sleeve member 21 is relatively easy, thereby improving the installation efficiency.
[0080] In one embodiment, part of the circumferential side wall of the cable sleeve member 21 protrudes to form a limiting ridge 211; the side wall of the central hole section 131 is spaced apart from the circumferential side wall of the cable sleeve member 21 to form a first gap and a second gap that are connected in sequence, and when the cable sleeve member 21 passes through the sub-hole section, the limiting ridge 211 is located in the first gap, and when the cable sleeve member 21 is in the locking position, the limiting ridge 211 is located in the second gap; wherein, the limiting ridge 211 is clearance-matched with the first gap so that the cable sleeve member 21 can rotate relative to the cable mounting member 10, and the limiting ridge 211 is interference-fitted with the second gap to lock the cable sleeve member 21 in the locking position.
[0081] Specifically, the sidewall of the central hole segment 131 includes a first arcuate surface 1313 and a second arcuate surface 1311 connected in the circumferential direction of the central hole segment 131. The first arcuate surface 1313 is spaced apart from the circumferential sidewall of the cable sleeve 21 to form a first gap, and the second arcuate surface 1311 is spaced apart from the circumferential sidewall of the cable sleeve 21 to form a second gap. The second gap is closer to the locking portion 113. In other words, the first arcuate surface 1313 is located near the corresponding sub-hole segment 132, and the second arcuate surface 1311 is located near the locking portion 113. Therefore, when the cable sleeve 21 rotates from the released position to the locked position, Figure 7 and Figure 8 During the clockwise rotation process shown in the figure, the limiting protrusion 211 enters the first gap between the first curved surface 1313 and the cable sleeve 21. At this point, because the limiting protrusion 211 is loosely fitted with the first gap, it can pass freely and then enter the second gap between the second curved surface 1311 and the cable sleeve 21. At this point, the limiting protrusion 211 and the second gap form an interference fit, thus restricting the degree of freedom between the cable sleeve 21 and the cable mounting member 10 in the radial direction of the central hole 131. This prevents the first limiting member 22 from disengaging from the locking slot 112 in the radial direction of the central hole 131.
[0082] See also Figure 7 and Figure 8 The centers of the first curved surface 1313 and the second curved surface 1311 are both located on the central axis of the central hole section 131, i.e., they are concentrically arranged. The radius of the first curved surface 1313 is greater than the radius of the second curved surface 1311. As such, the first gap between the first curved surface 1313 and the cable sleeve member 21 is greater than the second gap between the second curved surface 1311 and the cable sleeve member 21. Alternatively, in other embodiments, the first curved surface 1313 and the second curved surface 1311 may be arranged eccentrically relative to each other, as long as the first gap between the first curved surface 1313 and the cable sleeve member 21 is greater than the second gap between the second curved surface 1311 and the cable sleeve member 21.
[0083] In addition, in some embodiments, a transition surface 1312 is used between the two to avoid forming a step between the first curved surface 1313 and the second curved surface 1311, resulting in the limiting protrusion 211 being stuck at the connection between the first curved surface 1313 and the second curved surface 1311 during the rotation process.
[0084] It is worth mentioning that in some embodiments, the limiting ridges 211 include two symmetrically arranged ridges 211. That is, in this case, the two limiting ridges 211 are arranged on the same straight line. In this case, the two limiting ridges 211 simultaneously restrict the freedom of movement between the cable sleeve 21 and the cable mounting member 10 from opposite directions. For example, if the maximum distance between the two limiting ridges 211 is A, the diameter of the inner circle where the second curved surface 1311 is located is 0.1 to 0.5 mm smaller than A, and the diameter of the outer circle where the first curved surface 1313 is located is at least 0.1 mm larger than A.
[0085] The limiting ridge 211 protrudes from the circumferential sidewall of the cable sleeve 21. To ensure reliable engagement between the limiting ridge 211 and the second gap, one end of the limiting ridge 211 is connected to the sidewall of the first limiting member 22 facing the second limiting member 23, and the other end is connected to the sidewall of the second limiting member 23 facing the first limiting member 22. This means that during rotation of the cable sleeve, the limiting ridge 211 always remains engaged with the second gap.
[0086] In addition, see Figure 12 The limiting protrusion 211 may extend along the axial direction of the cable sleeve member 21 , or may extend at an angle to the axial direction of the cable sleeve member 21 , and this embodiment does not limit this.
[0087] In one embodiment, at least two first limiting members 22, locking portions 113 and first protrusions 111 are each provided, and at least two first limiting members 22 are evenly distributed in the circumferential direction of the cable sleeve 21, and at least two locking portions 113 and two first protrusions 111 are respectively provided in one-to-one correspondence with at least two first limiting members 22.
[0088] Specifically, one or more first position-limiting members 22 may be provided. To ensure that all first position-limiting members 22 can be locked into corresponding locking slots 112 in a single active rotation of a preset angle, at least two first position-limiting members 22 are evenly distributed around the circumference of the cable sleeve 21.
[0089] A larger number of first stoppers 22 can ensure a tighter abutment between the first stoppers 22 and the first sidewall 11. Furthermore, a larger number of first stoppers 22 can reduce the mating area of each first stopper 22 while maintaining the same mating area. This reduces the radial length of the first stoppers 22 along the cable sleeve 21, thereby lowering the strength requirement for each first stopper 22. Furthermore, the axial thickness of the first stoppers 22 along the cable sleeve 21 can be further reduced, thereby reducing the space occupied by the cable connection structure within the housing. However, a larger number of first stoppers can affect the mating between each first stopper 22 and the locking slot 112, potentially causing an unengaged first stopper 22 to interfere with other properly engaged first stoppers 22, making rotation of the cable sleeve 21 difficult. Therefore, to ensure both ease of installation and reduced size, it is preferred that two first stoppers 22 be provided. The following description uses the example of two first stoppers 22 as an example.
[0090] It can be understood that, at this time, the number or shape of the second limiting members 23 can be set to correspond to the two first limiting members 22.
[0091] See Figures 1 to 11 The two first limiting members 22 are symmetrically arranged on both sides of the cable sleeve member 21. Thus, the first side wall 11 is correspondingly provided with two locking portions 113 and two first protrusions 111. Therefore, when the cable sleeve member 21 rotates from the released position to the locked position, the left first limiting member 22b rotates counterclockwise until it engages with the guide inclined surface 1131 on the left side of the through hole 13 and is lifted up, then passes through the left locking portion 113 and enters the left locking slot 112. Simultaneously, the right first limiting member 22a rotates counterclockwise until it engages with the guide inclined surface 1131 on the right side of the through hole 13 and is lifted up, then passes through the right locking portion 113 and enters the right locking slot 112. It can be understood that when the rotation angle is 90°, on the plane where the first side wall 11 is located, the two groups of locking portions 113 and the first protrusion 111 form a point-symmetrical image with each other, and the symmetrical point is the intersection of the central axis of the central hole section 131 and the plane where the first side wall 11 is located.
[0092] In one embodiment, in a direction from the radial inside to the radial outside of the central hole section 131 , the guide slope 1131 extends obliquely in a direction away from the second side wall 12 .
[0093] See Figure 6In the radial direction of the central hole section 131, the radial outer edge of the guide bevel 1131 is higher than the radial inner edge of the guide bevel 1131, thereby forming a concave structure with the multiple guide bevels 1131. It will be appreciated that the concave structure formed by the multiple guide bevels 1131 allows the first stopper 22 to be engaged, thereby applying force to the cable sleeve 21 from all directions through the corresponding first stopper, ensuring that the central axis of the cable sleeve 21 is always collinear with the central axis of the central hole section 131, thereby facilitating the rotation of the cable sleeve 21.
[0094] It can be understood that in other embodiments, in the direction from the radial inside to the radial outside of the central hole section 131, the guide slope 1131 extends obliquely in the direction close to the second side wall 12, that is, at this time, multiple guide slopes 1131 form a raised frustum structure.
[0095] In one embodiment, the first limiting member 22 includes: a connecting portion 221 and a matching portion 222, the connecting portion 221 is fixedly connected to the circumferential side wall of the cable sleeve member 21; the matching portion 222 is arranged on the side of the connecting portion 221 facing the first side wall 11, and the matching portion 222 has a first matching bevel 2221 and a second matching bevel 2222 opposite to each other, the inclination of the first matching bevel 2221 is greater than that of the second matching bevel 2222, the first matching bevel 2221 matches with the locking portion 113, and the second matching bevel 2222 matches with the transition bevel 1111.
[0096] See Figures 9 to 12 The connecting portion 221 of the first position-limiting member 22 extends radially along the cable sleeve 21. A portion of the connecting portion 221 protrudes from a sidewall of the second position-limiting member 23 to form a mating portion 222. The mating portion 222 includes a first mating bevel 2221, a bottom surface, and a second mating bevel 2222, which are sequentially connected. The second mating bevel 2222 mates with the guide bevel 1131 and the transition bevel 1111. Specifically, when the cable sleeve 21 rotates from the released position to the locked position, the second mating bevel 2222 first mates with the guide bevel 1131, and the guide bevel 1131 lifts the first position-limiting member 22 via the first mating bevel 2221. When the first position-limiting member 22 rotates to the locked position, the mating portion 222 extends into the locking slot 112, and the second mating bevel 2222 mates with the transition bevel 1111. The slope of the second mating inclined surface 2222 may be consistent with the slope of the guiding inclined surface 1131 , thereby facilitating smoother movement of the second mating inclined surface 2222 on the guiding inclined surface 1131 .
[0097] See Figure 11The first mating inclined surface 2221 is used to cooperate with the side wall of the locking portion 113 facing the first protrusion 111, wherein the slope of the first mating inclined surface 2221 is very large and can be close to a vertical plane, so as to facilitate the mating portion 222 to be quickly inserted into the locking slot 112, and can also prevent the mating portion 222 from being detached after being inserted into the locking slot 112.
[0098] In one embodiment, a reinforcement portion 223 is protruded from a sidewall of the connecting portion 221 facing away from the matching portion 222 , and the reinforcement portion 223 is connected to the cable sleeve 21 .
[0099] See Figures 9 to 12 One end of the connecting portion 221 is fixedly connected to the circumferential side wall of the cable sleeve 21, while the other end is free, that is, the connecting portion 221 forms a cantilever beam structure. However, during the mating process between the mating portion 222 and the guide slope 1131, the mating portion 222 is subjected to a lifting force transmitted by the guide slope 1131. In addition, when the mating portion 222 is in the locking slot 112, there is also a squeezing force between the first mating slope 2221 and the locking portion 113, and between the second mating slope 2222 and the transition slope 1111. Therefore, the mating portion 222 transmits the above-mentioned force to the connecting portion 221, causing the cantilever beam connecting portion 221 to be easily deformed. Therefore, in this embodiment, a reinforcement portion 223 is protruded from the side wall of the connecting portion 221 away from the mating portion 222, and the reinforcement portion 223 is connected to the cable sleeve 21, thereby increasing the structural strength of the connecting portion 221 through the reinforcement ribs to reduce the deformation of the connecting portion 221.
[0100] In one embodiment, two reinforcing portions 223 are provided, and the two reinforcing portions 223 are spaced apart from each other; wherein the matching portion 222 is disposed close to one of the two reinforcing portions 223 .
[0101] See Figure 12 The two reinforcing portions 223 are spaced apart in the width direction of the connecting portion 221 , so that the first limiting member 22 forms a U-shaped structure to further improve the structural strength of the first limiting member 22 .
[0102] In one embodiment, at least a portion of the second sidewall 12 protrudes to form a second protruding portion 121 , and the second protruding portion 121 defines a through hole 13 . The orthographic projection of the second limiting member 23 on the second sidewall 12 covers the second protruding portion 121 .
[0103] See Figures 1 to 3 In this embodiment, the second protrusion 121 increases the thickness of the mating area on the cable mount 10, thereby improving the structural strength of the cable mount 10. In addition, the increased thickness of the second protrusion 121 also facilitates better compression of the first and second stoppers 22 and 23 onto the cable mount 10.
[0104] In addition, in this embodiment, the orthographic projection of the second limiting member 23 on the second side wall 12 covers the mating protrusion, that is, the second limiting member 23 can completely cover the second protrusion 231, so that the appearance of the cable mounting member 10 is more beautiful.
[0105] It is worth mentioning that, in this embodiment, in order to increase the structural strength of the cable sleeve 21 , the outer diameter of the side wall of the second limiting member 23 away from the first limiting member 22 gradually decreases.
[0106] In one embodiment, the first sidewall 11 has an annular flange 115 disposed around the through hole 13. The first stopper 22, the cable sleeve 21, the first sidewall 11, the inner sidewall of the annular flange 115, and the second stopper 23 collectively define a filling groove 116. The cable connection structure further includes a dispensing layer of adhesive that fills the filling groove 116.
[0107] Specifically, see Figures 3 to 6 , the annular flange 115 is arranged around the through hole 13. At this time, the length of the connecting portion 221 of the first limiting member 22 is smaller than the inner diameter of the annular flange 115, so that the first limiting member 22 can rotate in the annular flange 115. At this time, in addition to the through hole 13, the annular flange 115 also includes a portion of the first side wall 11, and this portion of the first side wall 11 is divided into two parts, left and right, by the through hole 13. At this time, the left and right parts are respectively formed with the aforementioned locking portion 113 and the first protruding portion 111. When the matching portion 222 of the first limiting member 22 is snapped into the locking slot 112, refer to Figure 4 On both sides of the first stopper 22, the sidewalls of the first stopper 22, the cable sleeve 21, the first sidewall 11, the inner sidewall of the annular flange 115, and the sidewall of the second stopper 23 facing the first stopper 22 collectively define a filling slot 116. At this point, the manufacturer can perform a glue dispensing process within the filling slot 116, and after the glue solidifies within the filling slot 116, form a glue layer (not shown).
[0108] In this embodiment, after the filling groove 116 is filled with the glue layer, the assembly reliability can be increased, and the user can be prevented from disassembling the cable outside the housing.
[0109] It can be seen that the present embodiment provides a cable connection structure, in which only the first limit member and one end portion of the cable sleeve member 21 extend into the first side wall 11 side of the cable mounting member 10, that is, the interior of the shell, and since the present embodiment adopts a fixing method in which the first limit member 22 and the second limit member 23 are clamped from both sides of the cable mounting member 10, its connection strength is mainly affected by the matching area, and its size in the cable length direction can also meet the required connection strength when it is small, so that its overall thickness is small, such as about 3.8 mm, thereby avoiding occupying too much space inside the electronic device, so that the appearance size of electronic devices such as cameras can be further reduced.
[0110] The present application also provides a camera comprising a housing and a cable connection structure, wherein the housing has a cable mounting member 10 of the cable connection structure. The specific structure of the cable connection structure is similar to the above-described embodiments. Since the present camera utilizes all the technical solutions of all the above-described embodiments, it at least has all the beneficial effects brought about by the technical solutions of the above-described embodiments, and no further details will be given here.
[0111] The above description is merely an optional embodiment of the present application and does not limit the patent scope of the present application. All equivalent structural transformations made using the contents of the present application specification and drawings under the inventive concept of the present application, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
