Description

Technical Field

[0001] The utility model relates to the technical field of Type C connector protection, in particular to a protection structure of a Type C connector joint. Background Art

[0002] The USB Type-C connector is a USB interface standard that is smaller than Type-A and Type-B. It can be used in both PCs (host devices) and external devices (slave devices, such as mobile phones). The connector of the Type-C connector is usually exposed to the outside, so in the prior art, a protective structure is often used to protect the connector from water and dust.

[0003] As mentioned in my country's public patent CN202221022622.0, a detachable waterproof USB Type C connector specifically mentions: "The connector body and the Type C connector are wrapped and protected by a movable protective cover and a protective cover, and the inside of the protective cover is sealed by a rubber protective pad to prevent water from entering, thereby preventing rainwater from entering and causing damage to the connector body and the Type C connector. The mounting part is separated from the countersunk hole and the mounting hole by rotating the mounting part, thereby facilitating the removal of the protective cover and the protective pad."

[0004] Although the utility model retrieved above realizes the sleeve protection of connectors and joints, we found that the technology still has certain defects during the specific simulation use:

[0005] During specific use, since a through groove is provided on the side of the movable protective sleeve for convenient entry and exit of the connector, when the movable protective sleeve is mounted on the connector, the through groove is in an open state, so the end face of the connector will still be exposed to the outside, and the protection of the connector is not comprehensive enough. At the same time, when the connector of the connector needs to be used, the movable protective sleeve needs to be slid into the protective sleeve. Since no limiting structure for the movable protective sleeve is provided between the movable protective sleeve and the protective sleeve, the movable protective sleeve will be withdrawn from the protective sleeve after entering the protective sleeve due to the influence of spring rebound, thereby causing the movable protective sleeve to cover the outside of the connector again, affecting the normal extension of the connector and connection with the equipment. Although the protective sleeve can be removed by the mounting part to use the connector normally, this method is cumbersome to operate, and the protective sleeve needs to be reinstalled after removal, which is inconvenient to operate.

[0006] Therefore, in response to the technical problems existing in the prior art, we have specifically designed a Type C connector joint protection structure that is simple to operate and has better protection effect. Utility Model Content

[0028] See also Figure 1-7A protective structure for a Type C connector joint comprises a protective shell 1 and a connector body 8 arranged inside the protective shell 1. The protective shell 1 can protect the connector body 8. A telescopic slide groove 102 is provided in the frame of the protective shell 1. A limiting slide groove 103 is provided on the inner wall of the telescopic slide groove 102. A telescopic frame 2 is slidably connected in the telescopic slide groove 102. The telescopic frame 2 protects the connector joint 801. A limiting slide frame 2 is fixed on one side of the telescopic frame 2. 04, two symmetrical spring steel sheets 201 are fixed on the side of the limit slide frame 204, and the limit slide frame 204 and the spring steel sheet 201 are both placed in the limit slide groove 103. A locking block 202 is fixed on the end of the spring steel sheet 201 away from the limit slide frame 204. The spring steel sheet 201 is in a compressed state in the limit slide groove 103. When the locking block 202 is placed in the locking hole 9, the spring steel sheet 201 rebounds to a straight state, and the side of the limit slide frame 204 and each spring steel sheet Reset springs 203 are connected to the positions on both sides of the sheet 201. The reset springs 203 are placed in the telescopic slide groove 102 and one end away from the limit slide frame 204 is fixed on the inner wall of the telescopic slide groove 102. The reset springs 203 play a role in withdrawing the telescopic frame 2 from the telescopic slide groove 102; a through hole 4 is provided on the other side of the telescopic frame 2, and two closing plates 7 are arranged in the through hole 4. The two closing plates 7 move away from each other and penetrate into the telescopic slide groove 2 301 opened in the inner cavity of the telescopic frame 2. A reset spring 2 302 is fixed on the inner wall of the telescopic slide groove 2 301, and the other end of the reset spring 2 302 is fixed on the closing plate 7. In order to prevent the closing plate 7 from scratching the surface of the connector joint 801, a soft protective sheet can be provided on the side surface of the closing plate 7 close to the connector joint 801, which can be a silicone sheet or a rubber sheet, so that the soft protective sheet contacts the connector joint 801; unlocking components 5 are provided on the top and bottom of the protective shell 1.

[0029] In this embodiment, the unlocking component 5 includes a support frame 501 fixed on the protective shell 1, a push rod 503 is movably inserted in the middle of the support frame 501, a button 502 is fixed at one end of the push rod 503, a reset spring 3 504 is sleeved on the rod body of the push rod 503, one end of the reset spring 3 504 is fixed on the button 502, and the other end is fixed on the support frame 501; locking holes 9 are opened on the outer wall of the protective shell 1 and at the position corresponding to each push rod 503, the locking block 202 and the push rod 503 are both inserted in the locking hole 9, and the end of the locking block 202 and the push rod 503 are designed to be round.

[0030] Specifically, the unlocking component 5 plays an unlocking role for the locking block 202, and the locking block 202 can be pushed out of the locking hole 9 by using the push rod 503. The return spring 504 is arranged on the push rod 503 to play the role of rebounding the push rod 503. The ends of the push rod 503 and the locking block 202 are designed to be round heads, which facilitates the end of the push rod 503 and the locking block 202 to withdraw from or enter the locking hole 9.

[0031] In this embodiment, limiting grooves 303 are provided on both sides of the inner wall of the telescopic groove 301, and limiting slides are fixed on both sides of the closing plate 7 close to the return spring 302. The limiting slides are slidably connected in the limiting grooves 303, and the inner side surface of the closing plate 7 is designed as an arc structure.

[0032] Specifically, a limiting slide plate is provided on the closing plate 7 to stabilize the stability of the closing plate 7 during movement, and the side of the closing plate 7 close to the connector joint 801 is designed to be an arc surface, which facilitates the cooperation with the connector joint 801 and pushes the two closing plates 7 away from each other to provide space for the connector joint 801 to pass through.

[0033] In this embodiment, a positioning cavity 101 is provided in the inner cavity of the protective shell 1, the connector body 8 is placed in the positioning cavity 101, a connector joint 801 is provided on one side of the connector body 8, and a through groove is provided on the side of the protective shell 1 close to the telescopic frame 2 for convenient passage of the connector joint 801. After passing through the through groove, the connector joint 801 is placed in the telescopic frame 2, and the end of the connector joint 801 is arc-shaped and corresponds to two closing plates 7; a locking frame 6 is detachably installed on the other side of the protective shell 1, and the locking frame 6 is fixed to the protective shell 1 by a quick-release screw 601, and a closed hole is provided on the side of the locking frame 6 for convenient passage of the tail end of the connector body 8.

[0034] Specifically, the connector body 8 is in direct contact with the inner wall of the protective shell 1, thereby improving the tightness of the two after connection and improving the overall stability. A detachable locking frame 6 is provided at the rear of the protective shell 1, and the locking frame 6 can be quickly disassembled by hand-tightening the quick-release screw 601, so that the locking frame 6 can be quickly disassembled and the connector body 8 can be taken out of the protective shell 1, thereby achieving the purpose of quick maintenance and repair. The inner wall of the locking frame 6 is also tightly fitted with the rear of the connector body 8, further improving the stability of the connector body 8 inside the protective shell 1.

[0035] During installation: the worker can insert the connector body 8 from the rear end of the protective shell 1 into the positioning cavity 101, and make the connector joint 801 pass through the slot into the telescopic frame 2, then install the locking frame 6 at the rear end of the protective shell 1 and make the rear end of the connector body 8 pass through the locking frame 6, and use the quick release screw 601 to lock the locking frame 6 at the rear end of the protective shell 1, thus completing the installation of the protective shell 1 on the connector body 8;

[0036] When in use: the staff pushes the telescopic frame 2, so that the telescopic frame 2 slides in the telescopic slide groove 102, and the limit slide frame 204 slides in the limit slide groove 103. When the telescopic frame 2 is moving, it pushes the return spring 203 to be compressed, and pushes the spring steel sheet 201 to move to the position of the locking hole 9. When the locking block 202 of the spring steel sheet 201 comes to the position of the locking hole 9, the locking block 202 is snapped into the locking hole 9 through the rebound of the spring steel sheet 201, thereby realizing the position positioning of the spring steel sheet 201 and the locking block 202, and fixing the position of the telescopic frame 2 and keeping it stationary;

[0037] At the same time, since the connector joint 801 needs to pass through the through hole 4 and be exposed to the outside for connection with other devices when the telescopic frame 2 slides into the telescopic slide groove 102, when the connector joint 801 is close to the through hole 4, it will contact the closing plate 7. Since one side of the closing plate 7 is designed as an arc structure, when the connector joint 801 contacts the closing plate 7, the two closing plates 7 will be pushed away from each other, and then open to provide a spacing for the connector joint 801 to pass through. Therefore, when the locking block 202 on the telescopic frame 2 is stuck in the locking hole 9, the telescopic frame 2 is fixed, that is, the connector joint 801 can always be exposed to the outside and is not affected by the telescopic frame 2. The connector joint 801 can be used normally for docking with other devices;

[0038] When the connector body 8 is not needed, the telescopic frame 2 needs to be used to cover the outside of the connector joint 801 again to protect it from water and dust. Therefore, the button 502 can be pressed, and the button 502 pushes the push rod 503, and the push rod 503 pushes the locking block 202 out of the locking hole 9. When the locking block 202 is no longer constrained by the engagement, the telescopic frame 2 is withdrawn from the telescopic slide groove 102 by the rebound action of the reset spring 203, so as to realize the re-protection of the connector joint 801. When the two closing plates 7 are no longer limited by the connector joint 801, the closing plates 7 are reclosed together by the rebound action of the reset spring 2 302, so as to realize the re-closing of the perforation 4 and the protection of the connector joint 801.

[0039] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
