Description

Technical Field

[0001] This utility model relates to the field of shielded interface technology, specifically a single-ended shielded interface. Background Technology

[0002] A single-ended shielded interface is a signal transmission interface that reduces electromagnetic interference by grounding at one end. Its core is to ground the shielding layer at one end, usually at the signal source end or the load end, to suppress interference caused by potential difference. It is suitable for short-distance signal transmission scenarios.

[0003] In existing technologies, single-ended shielded interfaces rely on simple spring contacts to limit and fix the inserted plug. After repeated insertion and removal, the single spring contact is prone to losing elasticity due to metal fatigue, resulting in a decrease in clamping force. The plug is prone to loosening, poor contact, or even falling off, which seriously affects the reliability of the connection. Furthermore, when the interface is subjected to external impacts, such as drops and squeezing, or during installation, the corners of the interface are prone to cracking or deformation due to the lack of reinforcement measures, leading to damage and affecting the service life. Utility Model Content

[0004] The purpose of this invention is to provide a single-ended shielded interface to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A single-ended shielded interface includes a main body, with a plurality of contacts installed on the outer wall of the main body near one end, a socket opened at one end of the main body, a plurality of pins fixedly installed inside the socket, and a limit mechanism provided on both inner side walls of the socket.

[0007] The limiting mechanism includes a limiting spring, which is fixedly installed on the inner wall of the socket. The outer wall of the limiting spring has several mounting slots, and a connecting shell is inserted into each of the mounting slots.

[0008] Preferably, each of the outer walls of the connecting shells is fixedly connected to a clamping plate, and the outer wall of the clamping plate is provided with a plurality of anti-slip grooves.

[0009] Preferably, a plurality of spring plates are fixedly connected to the inner wall of the mounting groove, and one end of each of the spring plates is fixedly connected to the clamping plate.

[0010] Preferably, the limiting mechanism further includes an arc-shaped groove, which is formed on the outer wall of the main body. A connecting spring is inserted inside the arc-shaped groove, and one end of the connecting spring is fixedly connected to the limiting spring.

[0011] Preferably, the outer side wall of the main body is provided with slots near the four corners, and a reinforcing plate is fixedly installed inside the slot. The slot is divided into two long slots by the reinforcing plate. A reinforcing plate one is inserted into one long slot, and a reinforcing plate two is inserted into the other long slot.

[0012] Preferably, the outer side wall has several irregular grooves, and irregular strips are inserted into each of the irregular grooves. One end of the first reinforcing plate and the second reinforcing plate are fixedly connected to the several irregular strips.

[0013] Preferably, a fixing plate is movably installed on the outer side wall of the main body near the four corners, and fixing nails are inserted into the outer side wall of several fixing plates. A fixing hole is opened on the outer side wall of the main body near the fixing nail, and the fixing hole fits with the fixing nail.

[0014] The beneficial effects of this utility model are:

[0015] 1. In this utility model, when the plug is inserted into the socket on the interface, the plug shell presses against the clamping plates on both sides. The clamping plates move into the mounting groove under force, and the connecting shell moves with the clamping plates. With the help of the spring plate compression and energy storage, the clamping plates can be moved out of the mounting groove to clamp the plug. The anti-slip groove set on the outer side of the clamping plate significantly increases the friction with the outer wall of the plug, effectively resisting the loosening or falling off of the plug caused by equipment vibration or accidental pulling. This effectively improves the reliability and stability of the plug connection and reduces the risk of poor contact.

[0016] 2. In this utility model, by setting reinforcing plates at the four corners of the main body and inserting reinforcing plate one and reinforcing plate two, reinforcing plate one and reinforcing plate two resist stresses in different directions, such as transverse compression and longitudinal bending, and are tightly locked to the reinforcing plates by irregular strips and irregular grooves, a solid cross-mesh support structure is formed, which enhances the structural strength of the corners of the interface body, enabling it to better withstand external impacts or installation stresses, effectively preventing cracking or deformation of the shell at weak points at the corners, and effectively extending the service life of the interface.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] A single-ended shielded interface, such as Figures 1-9 As shown, the device includes a main body 1. Several contact feet 2 are installed on the outer wall of the main body 1 near one end. A socket 3 is opened at one end of the main body 1. Several pins 4 are fixedly installed inside the socket 3. Limiting mechanisms are provided on both inner side walls of the socket 3. The limiting mechanisms include limiting springs 5. The limiting springs 5 ​​are fixedly installed on the inner wall of the socket 3. Several mounting grooves 8 are opened on the outer side wall of the limiting springs 5. Connecting shells 10 are inserted into the several mounting grooves 8.

[0031] The main body 1 is made of metal shell, and the contact 2 and pin 4 are grounded through internal circuit to form an electromagnetic shielding layer to block external interference signals.

[0032] Several connecting shells 10 are fixedly connected to the outer side walls of each of them. Several anti-slip grooves 12 are provided on the outer side walls of the clamps 11. By setting the anti-slip grooves 12, the friction between the outer wall of the clamps 11 and the plug that is subsequently inserted can be increased, so as to better limit and fix the plug and prevent it from falling off.

[0033] Several spring plates 9 are fixedly connected to the inner wall of the mounting groove 8. One end of each spring plate 9 is fixedly connected to the clamping plate 11. The limiting mechanism also includes an arc-shaped groove 6, which is opened on the outer wall of the main body 1. A connecting spring plate 7 is inserted inside the arc-shaped groove 6, and one end of the connecting spring plate 7 is fixedly connected to the limiting spring plate 5.

[0034] When in use, when the plug is inserted into the socket 3, the pin 4 is connected to the plug contact. At the same time, the plug shell presses against the two clamping plates 11. The clamping plates 11 are forced to move into the mounting groove 8. The connecting shell 10 moves with the clamping plates 11, which drives the spring plate 9 to compress and store energy, generating a reverse elastic force, which drives the clamping plates 11 to move out of the mounting groove 8 and clamp the plug. The anti-slip groove 12 can increase the contact friction and prevent the plug from shifting. Through the above operation, the stability of the plug insertion interface can be effectively improved, effectively resisting the loosening and falling off of the plug caused by equipment vibration or accidental pulling, effectively improving the reliability and stability of the plug connection, and reducing the risk of poor contact.

[0035] When the plug needs to be removed, pull one end of the connecting spring 7 to move the connecting spring 7 in the arc groove 6, which will drive the limiting spring 5 away from the outer wall of the plug, and then the plug can be pulled out.

[0036] Slots 14 are provided on the outer side wall of the main body 1 near the four corners. Reinforcing plates 15 are fixedly installed inside the slots 14. The slots 14 are divided into two long slots by the reinforcing plates 15. One long slot is filled with a reinforcing plate 16, and the other long slot is filled with a reinforcing plate 17. Several irregularly shaped slots 19 are provided on the outer side wall. Irregularly shaped strips 18 are inserted into the irregularly shaped slots 19. One end of the reinforcing plate 16 and the reinforcing plate 17 are fixedly connected to the irregularly shaped strips 18. The reinforcing plate 16 and the reinforcing plate 17 are respectively inserted into the long slots and locked to the reinforcing plates 15 by the irregularly shaped strips 18 and the irregularly shaped slots 19, forming a mesh support to support and reinforce the four corners of the main body 1.

[0037] Fixing plates 13 are movably installed on the outer side wall of the main body 1 and near the four corners. Fixing nails 20 are inserted into the outer side wall of several fixing plates 13. Fixing holes are opened on the outer side wall of the main body 1 near the fixing nails 20, and the fixing holes fit into the fixing nails 20. By inserting the fixing nails 20 into the fixing holes of the main body 1, the fixing plates 13 can be fixed to the main body 1. By pulling out the fixing nails 20, the fixing of the fixing plates 13 can be released, realizing quick disassembly and assembly of the fixing plates 13. This allows for easy unblocking of the slot 14, and the removal and insertion of the reinforcing plate 16 and the reinforcing plate 27 in the slot 14, facilitating the maintenance and replacement of the reinforcing plate 16 and the reinforcing plate 27.

[0038] Specifically, the reinforcing plates 16 and 17 at the four corners of the main body 1 can resist lateral and longitudinal stresses. At the same time, the engagement of the irregular strips 18 and the irregular grooves 19 and the locking of the reinforcing plate 15 form a mesh support, which supports and reinforces the four corners of the main body 1, enabling the main body 1 to better withstand external impacts or installation stresses, effectively preventing cracking or deformation of the shell at weak points at the corners, and effectively extending the service life of the interface. The fixing plate 13 is fixed to the main body 1 by fixing nails 20. When it is necessary to replace the reinforcing plates 16 and 17, the fixing nails 20 can be removed for overall disassembly.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
