Description

Technical Field

[0001] The present invention relates to the technical field of audio processors, and specifically to a digital audio processor with an efficient protection function. Background Art

[0002] An audio processor, also known as a digital processor, processes digital signals. Its internal structure generally consists of an input part and an output part. It has more complete functions internally, and some have processing modules that can be dragged and programmed, allowing users to freely build systems.

[0003] For existing audio processors, when used in a vehicle environment, for the convenience of installation and subsequent debugging, they will be placed in semi-open spaces such as under the seat and in the spare tire compartment for concealed installation. However, placing them in these exposed positions has the following problems: First, under the seat is close to the feet of the passengers, and the spare tire compartment is adjacent to the spare tire placement. The installation environment has more dust, and the sockets are prone to blockage due to dust ingress. Second, there are existing outer covers for audio devices that protect the sockets, but as a protective part, the outer cover completely wraps the sockets, and the connection position between the audio cable and the socket is completely blocked. When disassembling and assembling the audio cable, the outer cover needs to be removed, and the occlusion of the outer cover makes it impossible to directly observe the state of the audio cable and the socket, resulting in limited use. Summary of the Invention

[0004] The object of the present invention is to provide a digital audio processor with an efficient protection function, which can solve the technical problems in actual production:

[0005] Existing outer covers for audio devices that protect the sockets completely wrap the sockets, resulting in the connection position between the audio cable and the socket being completely blocked, and the outer cover needs to be removed when disassembling and assembling the audio cable.

[0006] To achieve the above object, the present invention is realized through the following technical solutions: It includes a main unit and a socket for connecting an audio cable. The socket is disposed through the end of the main unit. An installation frame is fixed at the position of the socket on the main unit, and a protection component that can be opened and closed and is used to block the socket is provided on the installation frame;

[0007] A driving structure for providing power to the protection component is provided on the installation frame. The driving structure closes the protection component and slides it towards the socket to block the socket. When the protection component is closed, it can deform to avoid the audio cable inserted in the installation frame and always clamp the audio cable during the movement towards the socket.

[0008] Preferably, the mounting bracket includes a frame body that forms an overhead cavity at the socket and a jack formed in the middle of the frame body corresponding to the socket position. The protection component includes a plugging structure installed at the jack. The plugging structure has a telescopic pin rod fixed to the mounting bracket and a baffle that can be driven by a driving structure to swing around the pin rod to connect the jack and the socket.

[0009] Preferably, the baffle is formed by dividing a circular plate into six equal parts. Each baffle is provided with a pin block groove in the chordal direction, and a pin block is slidably connected in the pin block groove. All the pin blocks are fixedly connected by a rotating ring. An elastic member is installed on the circumferential side wall of the rotating ring, and a sliding frame is installed at the bottom of the elastic member.

[0010] Preferably, a middle seat is rotatably installed at one end of the rotating ring away from the baffle. The lower part of the middle seat is slidably connected to the sliding frame, and a sliding column is installed at the lower end of the middle seat.

[0011] Preferably, the driving structure has a connecting frame that drives the middle seat to move back and forth. The connecting frame is movably connected to the sliding frame and enables the sliding frame to slide horizontally. When the sliding frame slides, it drives the rotating ring to rotate through the elastic member. A second sliding hole is formed in the main body of the connecting frame for slidably connecting with the sliding column when the connecting frame slides horizontally.

[0012] Preferably, the elastic member includes a first fixed section, a middle section, and a second fixed section. A first bending part is provided at the connection between the first fixed section and the middle section, and a second bending part is provided at the connection between the middle section and the second fixed section. The top of the first fixed section is fixedly connected to the rotating ring, and the bottom of the second fixed section is fixedly connected to the sliding frame.

[0013] Preferably, the protection component further includes an auxiliary structure sleeved on the middle of the socket. A first sliding hole is formed in the lower part of the main body, and a square rod is installed through the first sliding hole. The front end of the square rod is movably connected to the sliding frame, and a clamping frame is fixedly installed at the rear end of the square rod. The upper part of the clamping frame is lapped with the auxiliary structure for driving the sliding frame to move up and down.

[0014] Preferably, the auxiliary structure includes a fixed ring. A rotary cap is installed at the front end of the fixed ring. A moving ring is arranged in the sliding space formed between the rotary cap and the fixed ring. The moving ring can slide back and forth in the sliding space. Eccentric part one and eccentric part two are arranged in a mirror image at the front end of the moving ring.

[0015] Preferably, the radii of the eccentric part one and the eccentric part two are the same, and the eccentric part one is higher than the eccentric part two and arranged in a staggered manner. The upper part of the clamping frame is semicircular and has a diameter consistent with that of the eccentric part one and the eccentric part two.

[0016] Preferably, a counterweight is arranged in the sliding space. An inclined end face is arranged on the side of the counterweight facing the fixed ring. An inclined surface groove is arranged on the upper part of the fixed ring to cooperate with the inclined end face to make the counterweight slide forward. The front end of the fixed ring extends out a support ear so that the moving ring can only slide back and forth.

[0017] By adopting the foregoing technical solutions, the beneficial effects of the present invention are as follows:

[0018] 1. Through the setting of the protection component, the baffle can be opened and closed synchronously driven by the rotating ring. When closed, it can block the middle hole of the socket to prevent foreign objects from entering. Moreover, the rotating ring and the intermediate seat, as transmission components, can cooperate with the baffle to move towards the socket to wrap the front end of the socket, completing a more perfect closed protection. At the same time, when an audio cable is inserted into the socket, the baffle can be used for compensating and tightly inserting the audio cable and positioning during use.

[0019] 2. Through the setting of the elastic member and the auxiliary structure, when opening and closing the baffle, the elastic member serves as a transmission member to enable the rotating ring to rotate smoothly. The auxiliary structure can change the state of the elastic member. When dealing with an empty socket, the auxiliary structure makes the elastic member rigidly connected to the rotating ring for positioning the rotating ring. When dealing with a socket with an audio cable, the auxiliary structure further stretches the elastic member to store energy so that the rotating ring can press the audio cable, but the elastic member is still in an elastic state, enabling the baffle to slide relative to the audio cable when the insertion is in place and the baffle continues to move backward.

Detailed implementation mode

[0033] Embodiment:

[0034] This embodiment provides a digital audio processor with an efficient protection function, including a main body 1 and a socket 12 for connecting an audio cable 2. Referring to Figure 1 and 2 , the socket 12 is arranged through the end of the main body 1, and a mounting bracket 3 is fixed at the position of the mounting panel 11 of the main body 1. A protection component that can be opened and closed and is used to block the socket 12 is arranged on the mounting bracket 3;

[0035] A driving structure 4 for providing power to the protection component is arranged on the mounting bracket 3. The driving structure 4 closes the protection component and slides towards the socket 12 to block the socket 12. When the protection component is closed, it can deform to avoid the audio cable 2 inserted in the mounting bracket 3 and always clamp the audio cable 2 during the movement towards the socket 12.

[0036] Among them, the driving structure 4 can provide driving forces for left - right and front - back movements, enabling the protection component to open, close, and move front - back. The protection component can act on all the sockets 12 simultaneously. When the protection component is opened, the front parts of all the sockets 12 can be opened for normal insertion and extraction of the audio cable 2. When the protection component is closed, the holes in all the sockets 12 can be blocked to prevent foreign objects from entering. At the same time, for the case where some or all of the sockets 12 are connected with the audio cable 2, for the sockets 12 with the audio cable 2 inserted, the protection component will avoid the audio cable 2 through its own deformation and continue to perform the closing action to ensure that the unused sockets 12 are blocked and protected. And after closing, the protection component can clamp the audio cable 2 and move backward, push the audio cable 2 that is not inserted in place into the socket 12 and insert it tightly, and always keep clamping the audio cable 2 during use to prevent the audio cable 2 without a self - locking function (such as the audio cable 2 with a phono plug) from falling off.

[0037] In an embodiment of the present invention, referring to Figure 2 , the mounting bracket 3 includes a frame body 31 that forms an overhead cavity at the socket 12 and a jack 32 opened in the middle of the frame body 31 corresponding to the position of the socket 12. The protection component includes a blocking structure 5 installed at the jack 32. Referring to Figure 3 , the blocking structure 5 has a pin rod 55 that can be telescoped and fixed to the mounting bracket 3 and a baffle 51 that can be driven by the driving structure 4 to swing around the pin rod 55 to communicate the jack 32 with the socket 12;

[0038] Since the pins of the socket 12 are soldered to the circuit board inside the host 1, the socket 12 is vulnerable to impact, which may cause poor contact at the soldering points. The front end of the socket 12 is in the overhead cavity and is blocked by the frame body 31, which can prevent foreign objects from directly hitting the socket 12 during handling and use, providing stable protection for the socket 12. And the frame body 31 can provide an installation carrier for the blocking structure 5. Moreover, during use, since there is a gap between the frame body 31 and the mounting panel 11 and the open jack 32 does not completely block the socket 12, the user can observe the situation of the socket 12 from the side gap and the position of the jack 32. At the same time, the jack 32 can play a guiding role when inserting the audio cable 2, facilitating the alignment and insertion of the audio cable 2 with the socket 12. It should be noted that after the audio cable 2 is inserted into the jack 32, the gap between the jack 32 and the audio cable 2 is small, only ensuring smooth insertion and extraction. When the audio cable 2 is squeezed along the front - end face direction of the frame body 31, the audio cable 2 will be supported by the inner wall of the jack 32 to resist the pressure, avoiding being directly transmitted to the audio cable 2 and the socket 12 when subjected to an external force perpendicular to the axis, resulting in bending damage.

[0039] In an embodiment of the present invention, regarding the baffle 51, referring to Figure 3, the baffle 51 is formed by dividing a circular plate into six equal parts. Each baffle 51 is provided with a pin block groove 56 in the chordal direction. A pin block 53 is slidably connected in the pin block groove 56. All the pin blocks 53 are fixedly connected through a rotating ring 52. An elastic member 59 is installed on the circumferential side wall of the rotating ring 52, and a sliding frame 58 is installed at the bottom of the elastic member 59;

[0040] Since the plate body 511 of the baffle 51 has an arc-shaped side and two straight sides 512, all the baffles 51 can be put together to form a circular plate when they approach each other. The pin rod 55 is divided into a rod body and a sleeve. The rod body is rotatably installed at the rear end of the sleeve and can slide back and forth. The front end of the sleeve is fixed on the frame body 31. The rear end of the rod body penetrates and is fixed at the included angle position of the arc-shaped side and one of the straight sides 512. A pin block groove 56 is provided in the chordal direction of the baffle 51 and is connected to the rotating ring 52 through the pin block 53. When the rotating ring 52 rotates in reverse, the pin block 53 slides in the pin block groove 56, which can push the baffle 51 to rotate in reverse around the pin rod 55. At this time, the space between the jack 32 and the socket 12 is opened to facilitate the insertion of the audio cable 2. When the rotating ring 52 rotates forward, it can drive all the baffles 51 to rotate forward and form a circular plate, separating the space between the jack 32 and the socket 12 to prevent foreign objects from entering the inner hole of the socket 12 from the jack 32 position.

[0041] In an embodiment of the present invention, regarding the middle seat 54, refer to Figure 3 , a middle seat 54 is rotatably installed at one end of the rotating ring 52 away from the baffle 51. The lower part of the middle seat 54 is slidably connected to the sliding frame 58, and a sliding column 57 is installed at the lower end of the middle seat 54;

[0042] The middle seat 54 serves as an installation carrier to rotatably install the rotating ring 52 at the front end of the middle seat 54. A hole with the same inner diameter as the rotating ring 52 is opened in the upper part of the middle seat 54, and it is ensured that the center of the rotating ring 52 is directly opposite to the centers of the jack 32 and the socket 12 front and back, so that the audio cable 2 can be smoothly inserted and removed without being blocked by the middle seat 54 and the rotating ring 52, and it can also prevent the audio cable 2 from being worn during insertion and removal to the rotating ring 52.

[0043] In an embodiment of the present invention, refer to Figure 3 , the driving structure 4 has a connecting frame 45 that drives the middle seat 54 to move back and forth. The connecting frame 45 is movably connected to the sliding frame 58 and enables the sliding frame 58 to slide horizontally. When the sliding frame 58 slides, it drives the rotating ring 52 to rotate through the elastic member 59. A sliding hole two 453 is opened in the main body 451 of the connecting frame 45 for slidably connecting with the sliding column 57 when the connecting frame 45 slides horizontally;

[0044] In an embodiment of the present invention, the implementation scenario is specifically: refer to Figure 5 , the connecting frame 45 is used as a power member. In the initial state of the connecting frame 45, the baffle 51 is in an open state. At this time, when the connecting frame 45 moves leftward, it can drive the sliding frame 58 to slide horizontally to the left. The sliding column 57 slides in the sliding hole two 453, which can ensure that the middle seat 54 does not move leftward. Refer toFigure 6 , and then the swivel 52 is rotated forward at the front end of the intermediate seat 54 by the elastic member 59, referring to Figure 7 At this time, the baffle 51 rotates forward and closes to separate the space between the jack 32 and the socket 12, and then the connecting frame 45 moves backward. Because the pin 55 can be extended, the connecting frame 45 can drive the baffle 51, the rotating ring 52 and the intermediate seat 54 to move backward synchronously. Figure 9 The rearward-opening cover-shaped structure composed of the baffle 51, the swivel 52 and the middle seat 54 can be mounted on the portion of the unused socket 12 protruding from the mounting panel 11 to wrap the front portion of the socket 12. The swivel 52 and the middle seat 54 can be used to increase the protection range and prevent debris from entering the interior of the socket 12 through the gap between the baffle 51 and the front end of the socket 12.

[0045] In one embodiment of the present invention, referring to Figure 8 The elastic member 59 includes a fixed section 1 591, a middle section 593 and a fixed section 2 594. A bending portion 1 595 is provided at the connection between the fixed section 1 591 and the middle section 593, and a bending portion 2 596 is provided at the connection between the middle section 593 and the fixed section 2 594. The top of the fixed section 1 591 is fixedly connected to the swivel 52, and the bottom of the fixed section 2 594 is fixedly connected to the slide 58.

[0046] In one embodiment of the present invention, the elastic member 59 is made of a metal material with good toughness as a whole, and is designed to be thinner at the bending portion 1 595 and the bending portion 2 596 to ensure that the elastic member 59 can be bent at these two positions.

[0047] In one embodiment of the present invention, the material of the elastic member 59 is not limited, and it is only ensured that the fixed section 1 591, the middle section 593 and the fixed section 2 594 are hard parts, and the bending portion 1 595 and the bending portion 2 596 can be flexibly deformed when subjected to force to ensure that the fixed section 1 591, the middle section 593 and the fixed section 2 594 can be relatively displaced around the bending portion 1 595 and the bending portion 2 596.

[0048] In one embodiment of the present invention, referring to Figure 2 A slide 41 is fixed between the connecting frames 45, a clamping head 42 is installed on the rear side of the slide 41, a limiting plate 43 corresponding to the clamping head 42 is installed on the front side of the installation panel 11, and positioning grooves 44 are opened on the upper and lower side walls of the limiting plate 43.

[0049] In one embodiment of the present invention, the implementation scenario is specifically as follows: when the audio cable 2 is not connected to the socket 12, refer to Figure 7 When the carriage 58 slides horizontally to the left, the second fixed section 594 is driven to move leftward, and then the first fixed section 591 is moved leftward. At this time, the elastic member 59 acts as a transmission member to drive the rotating ring 52 to rotate forward and close the baffle 51. Figure 8When the slide 58 moves to the leftmost end, the bending portion 1 595 passes the lowest point of the swivel 52 and is located at the lower left corner of the swivel 52, while the bending portion 2 596 is basically symmetrically located at the lower left corner of the swivel 52. Because the swivel 52 will squeeze the elastic member 59 downward, the bending portion 1 595 and the bending portion 2 596 are in a compressed state at this time, and are pressed against the swivel 52 on the left and the right. Compared with only using the pulling of the elastic member 59 to position the swivel 52, the pressing of the bending portion 1 595 and the bending portion 2 596 can play a more stable limiting role on the swivel 52. In the vibration environment of the vehicle or close to the audio equipment, it can ensure that the swivel 52 will not reverse and thus ensure that the baffle 51 can be stably in a position close to each other to block the front end of the socket 12, and the protective component will not be unable to fix the baffle 51 due to the elastic deformation of the elastic member 59 itself during use.

[0050] In one embodiment of the present invention, the implementation scenario is specifically as follows: when the driving structure 4 drives the protective component to perform the closing action, a manual execution mode can be adopted, a slide 41 is installed in the front of the connecting frame 45, and the slide 41 passes through the frame 31 through the rectangular hole in the middle of the frame 31 and extends forward, which is convenient for handholding and can drive all the connecting frames 45 to move synchronously. The slide 41 can move forward, backward, left and right, and then can drive the connecting frame 45 to move. When the socket 12 is closed, refer to Figure 11 When the audio cable 2 is connected to the socket 12, the handheld slide 41 moves left, the slide 58 slides horizontally to the left, and the rotation path of the baffle 51 is blocked by the audio cable 2. When the straight edge 512 of the baffle 51 contacts the audio cable 2, it stops rotating, and the continued movement of the slide 58 will stretch the elastic member 59. Figure 12 At this time, the elastic bending part 1 595 and the bending part 2 596 are tightened and stored, and cooperate with the baffle 51 to squeeze the audio line 2, and then push the slide 41 backward, so that the rear end of the slide 41 contacts the limit plate 43. The limit plate 43 can be used as a limit for the pushing depth, ensuring that the slide 41 can move backward to drive the swivel 52 and the middle seat 54 to cover the front part of the socket 12, and the baffle 51 will not directly squeeze the front end of the socket 12, leaving a suitable gap to prevent the baffle 51 and the socket 12 from squeezing each other and causing deformation to affect normal use. Figure 10 After the slide 41 moves backward, the clamping head 42 will align with the positioning groove 44, so that the elastic member 59 remains in the stretched and force-accumulating state. At this time, the limit plate 43 cooperates with the slide 41 and the protective component to fix the audio cable 2, and the protective component will not be unable to clamp and fix the audio cable 2 due to its own displacement.

[0051] In one embodiment of the present invention, the implementation scenario is specifically as follows: Figure 11, because there are a large number of audio cables 2, and the sockets 12 are closely spaced from each other to save space, resulting in mutual occlusion between the audio cables 2 after installation. It is not possible to quickly and timely detect the audio cables 2 that are not inserted in place. When the carriage 58 and the baffle 51 are moved backward as a whole and approach the socket 12, the audio cables 2 can be driven closer to the socket 12 to insert the audio cables 2 that are not inserted in place tightly. For the audio cables 2 that are already inserted tightly, when the carriage 58 and the baffle 51 are moved backward as a whole, they will slide relative to the audio cables 2 without affecting the overall backward sliding. In order to ensure that the audio cables 2 are inserted tightly, the carriage 41 can be pushed backward and then pushed to the right. At this time, the baffles 51 will be driven to move away from each other to release the audio cables 2. Then, the carriage 41 is pulled forward to reset the separated baffles 51, and then the carriage 41 is moved to the left to repeat the actions of closing the baffles 51 and pushing them backward, which can push and insert the audio cables 2 multiple times, making the use flexible and efficient.

[0052] In one embodiment of the present invention, referring to Figure 4 , the protection component further includes an auxiliary structure 6 sleeved on the middle part of the socket 12. A first sliding hole 452 is opened at the lower part of the main body 451. A square rod 46 is installed through the first sliding hole 452. The square rod 46 can only slide up and down and cannot rotate in the first sliding hole 452, ensuring that the clamping frame 47 is always in a vertical state. The front end of the square rod 46 is movably connected to the carriage 58. When the carriage 58 moves backward, the square rod 46 and the clamping frame 47 can remain in their current positions and do not affect the backward movement of the carriage 58. The rear end of the square rod 46 is fixedly installed with a clamping frame 47. Among them, the upper part of the clamping frame 47 is lapped with the auxiliary structure 6 to drive the carriage 58 to move up and down. The up and down movement of the carriage 58 can change the distance between the carriage 58 and the bottom of the rotating ring 52, thereby changing the energy storage state of the elastic member 59;

[0053] Please also refer to Figure 4 , the auxiliary structure 6 includes a fixed ring 61. A rotary cap 64 is installed at the front end of the fixed ring 61. A moving ring 65 is arranged in the sliding space formed between the rotary cap 64 and the fixed ring 61. The moving ring 65 can slide back and forth in the sliding space. The front end of the moving ring 65 is provided with an eccentric part one 67 and an eccentric part two 68 arranged in an image manner. The eccentric part one 67 is located behind the eccentric part two 68, and the top of the eccentric part one 67 is higher than the top surface of the eccentric part two 68, while the bottom of the eccentric part two 68 is lower than the bottom surface of the eccentric part one 67.

[0054] Please also refer to Figure 4, a counterweight 63 is arranged in the sliding space. The counterweight 63 is provided with an inclined end face on the side facing the fixed ring 61. Moreover, an inclined surface groove 62 for cooperating with the inclined end face to make the counterweight 63 slide forward is arranged on the upper part of the fixed ring 61. When the moving ring 65 is not subjected to a backward extrusion force, the counterweight 63 is at the bottommost part of the inclined surface groove 62. Because the inclined surface of the counterweight 63 cooperates with the inclined surface groove 62, it can ensure that the counterweight 63 is in the most forward position. At this time, the first eccentric part 67 and the second eccentric part 68 of the moving ring 65 completely protrude. Among them, the front end of the fixed ring 61 extends out an ear 66 to make the moving ring 65 slide only back and forth, preventing the change of the position relationship between the high points and the low points of the first eccentric part 67 and the second eccentric part 68 caused by the rotation of the moving ring 65.

[0055] In an embodiment of the present invention, the implementation scenario is specifically as follows: When the audio cable 2 is not connected to the socket 12, refer to Figure 5 , the counterweight 63 slides forward and downward, and pushes the first eccentric part 67 forward by its own gravity to align with the position of the card holder 47. The upper part of the card holder 47 is semi-circular, and the inner diameter is consistent with the outer diameter of the first eccentric part 67. Refer to Figure 7 , at this time, the protection component moves to the left, and the card holder 47 will press tightly on the right side of the first eccentric part 67. When the baffle 51 blocks the socket 12, the card holder 47 overlaps with the center of the first eccentric part 67. At this time, the top surface of the first eccentric part 67 squeezes the inner wall of the top of the card holder 47, lifting the entire sliding frame 58, so that the elastic member 59 in an almost horizontal state is squeezed. At this time, the first bent part 595 and the second bent part 596 are further compressed and deformed, and the overlapping positions of the first fixed section 591, the middle section 593 and the second fixed section 594 are mutually squeezed to form an integral body without gaps, which is rigidly connected to the rotating ring 52, providing more stable extrusion and limit for the rotating ring 52, and making the position of the baffle 51 more stable.

[0056] In an embodiment of the present invention, the implementation scenario is specifically as follows: When the audio cable 2 is connected to the socket 12, refer to Figure 11 , the audio cable 2 will contact the front end of the second eccentric part 68 and squeeze the moving ring 65 sleeved in the middle of the socket 12 backward. At this time, the counterweight 63 is pressed to slide backward and upward, and at this time, the second eccentric part 68 moves backward to align with the position of the card holder 47. Please also refer to Figure 11, at this time, the protection component moves leftward, and the clamping frame 47 will be pressed against the right side of the second eccentric part 68 and be extruded downward by the bottom surface of the second eccentric part 68, thereby pressing down the entire carriage 58, causing the bottom of the elastic member 59 in the straightened and energy-storing state to move further downward away from the rotating ring 52. At this time, the first bent part 595 and the second bent part 596 are further stretched and deformed, causing the first bent part 595 and the second bent part 596 to generate a greater resilience, enabling the rotating ring 52 to drive the baffle 51 to further clamp the audio cable 2, providing a greater clamping force for the positioning of the audio cable 2. However, at this time, the first bent part 595 and the second bent part 596 are still in an elastic state. When the rotating ring 52 and the baffle 51 are pushed and moved backward, if the audio cable 2 has been inserted in place, the baffle 51 can utilize the deformation of the elastic member 59 to smoothly slide along the audio cable 2, ensuring the smooth progress of subsequent operations.

[0057] In an embodiment of the present invention, at the position where the carriage 58 is connected to the elastic member 59, an opening frame 592 with an upward opening is provided. The opening frame 592 has a certain depth in the height direction and can accommodate the elastic member 59. When the carriage 58 moves leftward and the elastic member 59 is compressed and stacked, the lower edge of the rotating ring 52 will be inserted into the top opening of the opening frame 592. When the driving structure drives the carriage 58, the rotating ring 52, and the baffle 51 to move backward as a whole, the elastic member 59 is in a state of being limited by the opening frame 592, and the situation where the first fixed section 591, the middle section 593, and the second fixed section 594 slide relative to each other in the front and rear directions will not occur, ensuring that the positions of the first bent part 595 and the second bent part 596 are controllable and that the elastic energy storage is not released due to torsion in the front and rear directions, so as to further ensure the stable positioning of the baffle 51. Moreover, the inner wall of the front side of the opening frame 592 will squeeze the outer wall of the front side of the rotating ring 52, not only driving the rotating ring 52 to move backward through the elastic member 59, but also ensuring that the baffle 51 can move backward smoothly close to the socket 12.

[0058] Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather will conform to the widest scope consistent with the principles and novel features disclosed herein.
