Description

Technical Field

[0001] The invention relates to a high-performance electromagnetic shielding separation electric connector socket. Background Art

[0002] Weaponry and equipment models typically require that electrical connectors provide electromagnetic shielding when mated to prevent interference from other high-frequency electromagnetic waves and the resulting communication errors. However, as models evolve, there is a further requirement that the individual socket mating surfaces, after the header is separated, provide high-performance electromagnetic shielding to shield against other electromagnetic interference within the system when separated.

[0003] Currently, there are two main methods for achieving electromagnetic shielding of electrical connectors. One is plug-in electromagnetic shielding, which is relatively mature and has been successfully applied to multiple models, such as JF20 and YF15 electrical connectors. However, it cannot achieve the electromagnetic shielding function of the socket alone. The other is shielding of the plug-in surface of the individual socket, but the opening is large, the metal contact of the plug-in surface is discontinuous, and the electromagnetic shielding effect is weak. The above electromagnetic shielding methods can no longer meet the use requirements of high-performance individual socket shielding. Summary of the Invention

[0004] The object to be achieved by the present invention is to provide a high-performance electromagnetic shielding separation electrical connector socket, which can simultaneously achieve plug-in shielding and individual socket electromagnetic shielding and has strong applicability.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: a high-performance electromagnetic shielding separation electrical connector socket, comprising a shell and a cable cover arranged on the shell, a movable layer and a back layer are provided in the shell, the back layer is provided with a jack, the movable layer is provided with a double pin, a locking sleeve and a spring are provided between the movable layer and the back layer, a shielding metal plate is sleeved on the outer wall of the locking sleeve, and the outer wall of the shielding metal plate is attached to the inner wall of the shell, a conductive rubber ring is provided between the shielding metal plate and the locking sleeve, a crown spring is provided on the shielding metal plate, and a tightening ring is provided in the shell to resist the shielding metal plate.

[0006] Preferably, the shielding metal plates include two pieces, and the crown spring is arranged between the two shielding metal plates.

[0007] Preferably, the conductive rubber ring is arranged between two shielding metal plates.

[0008] Preferably, a positioning shoulder is provided in the shell and abuts against the shielding metal plate.

[0009] Preferably, the shielding metal plate is an aluminum alloy plate.

[0010] Preferably, a spring sleeve is provided on the movable layer, a spring seat is provided on the back layer, one end of the spring abuts against the spring sleeve, and the other end of the spring abuts against the spring seat.

[0011] Preferably, the spring seat includes a fixed section fixed on the back layer, and a guide section matched with the spring sleeve, and the guide section is provided with a fixing groove for fixing the spring.

[0012] Preferably, the shielding metal plate is provided with a through hole connected to the spring sleeve, and the outer side wall of the spring sleeve is provided with a step that abuts against the shielding metal plate.

[0013] Preferably, the movable layer is provided with a rivet sleeve which is sleeved on the lock sleeve.

[0014] Preferably, an external thread is provided on the outer side wall of the tightening ring, and an internal thread is provided inside the shell.

[0015] In summary, the advantages of the present invention are as follows: by arranging a shielding metal plate on the outer side wall of the lock sleeve, and since a crown spring is provided on the shielding metal plate, and a conductive rubber ring is provided between the shielding metal plate and the lock sleeve, when the plug and the socket are separated, the active layer moves under the action of the spring, so that the double pins on the active layer contact the crown spring, thereby achieving electrical continuity. Only after the active layer is completely separated from the back layer contact piece, the other end of the double pins contacts the crown spring, which can effectively prevent the problem of socket signal short circuit. At the same time, the pre-tightening effect of the active layer spring can prevent the occurrence of contact gaps in a vibration environment. Therefore, after the socket is separated, the electromagnetic shielding function of the socket mating surface is formed by the mutual contact and cooperation between the socket shell, the shielding metal plate, the crown spring, the double pins, the conductive rubber ring, and the lock sleeve, which can simultaneously achieve mating shielding and individual socket electromagnetic shielding. The product has strong applicability and strong shielding capability compared to other open shielding, with a leakage attenuation of not less than 70dB. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] like Figure 1 As shown, a high-performance electromagnetic shielding separation electrical connector socket includes a shell 1 and a cable cover 2 arranged on the shell 1, an active layer 3 and a back layer 4 are provided in the shell 1, a jack 5 is provided on the back layer 4, a double pin 6 is provided on the active layer 3, a locking sleeve 7 and a spring 8 are provided between the active layer 3 and the back layer 4, a shielding metal plate 9 is sleeved on the outer wall of the locking sleeve 7, and the outer wall of the shielding metal plate 9 is attached to the inner wall of the shell 1, a conductive rubber ring 10 is provided between the shielding metal plate 9 and the locking sleeve 7, a crown spring 11 is provided on the shielding metal plate 9, and a tightening ring 12 is provided in the shell 1 to abut against the shielding metal plate 9.

[0021] By arranging a shielding metal plate 9 on the outer wall of the lock sleeve 7, and since a crown spring 11 is provided on the shielding metal plate 9, and a conductive rubber ring 10 is provided between the shielding metal plate 9 and the lock sleeve 7, when the plug and the socket are separated, the active layer 3 moves under the action of the spring 8, so that the double pins 6 on the active layer 3 contact the crown spring 11, thereby achieving electrical continuity. Only after the active layer 3 and the back layer 4 contact piece are completely separated, the other end of the double pins 6 contacts the crown spring 11, which can effectively prevent the problem of socket signal short circuit. At the same time, the pre-tightening effect of the spring 8 of the active layer 3 can prevent the occurrence of contact gaps in a vibration environment. Therefore, after the socket is separated, the electromagnetic shielding function of the socket mating surface is formed through the mutual contact and cooperation between the socket housing 1, the shielding metal plate 9, the crown spring 11, the double pins 6, the conductive rubber ring 10, and the lock sleeve 7, which can simultaneously achieve mating shielding and individual socket electromagnetic shielding. The product has strong applicability and strong shielding capability compared to other open shielding, with a leakage attenuation of not less than 70dB.

[0022] The shielding metal plates 9 include two pieces, and the crown spring 11 is arranged between the two shielding metal plates 9 to facilitate the installation and fixation of the crown spring 11. In this embodiment, mounting grooves can be provided on both shielding metal plates 9 to facilitate the overall fixed installation and avoid relative sliding between the crown spring 11 and the shielding metal plates 9, thereby ensuring the contact between the crown spring 11 and the double pins 6. The conductive rubber ring 10 is arranged between the two shielding metal plates 9. In this embodiment, a groove can be provided on each of the two shielding metal plates 9, and a receiving groove for accommodating the conductive rubber ring 10 is formed between the two grooves, thereby ensuring the contact and fit between the conductive rubber ring 10, the shielding metal plate 9 and the lock sleeve 7. A positioning shoulder 13 is provided in the housing 1 to abut against the shielding metal plate 9, thereby realizing the positioning of the shielding metal plate 9 and ensuring the stability of the installation of the shielding metal plate 9. The shielding metal plate 9 is an aluminum alloy plate, which makes the shielding metal plate have good shielding performance.

[0023] The movable layer 3 is provided with a spring sleeve 14, and the back layer 4 is provided with a spring seat 15. One end of the spring 8 abuts against the spring sleeve 14, and the other end of the spring 8 abuts against the spring seat 15, thereby achieving the installation and fixation of the spring 8 and ensuring the stability of the spring 8 when compressed and reset. The spring seat 15 includes a fixing section 16 fixed to the back layer 4, and a guide section 17 cooperating with the spring sleeve 14. The guide section 17 is provided with a fixing groove 18 for fixing the spring 8. The fixing section 16 enables the spring seat 15 to be stably installed on the back layer 4. In this embodiment, the fixing section 16 is fixed to the back layer 4 by a nut. Specifically, the outer wall of the fixing section 16 is provided with an external thread, and the nut is set on the external thread. During installation, the external thread passes through the back layer 4 and is locked by the nut. The provision of the guide section 17 ensures the straightness of the movable layer 3 during movement when plugged in and out of the socket, because the guide section 17 is set in the spring sleeve 14. The provision of the fixing groove 18 enables the installation and fixation of the spring 8.

[0024] The shielding metal plate 9 is provided with a through-hole connected to the spring sleeve 14. The outer wall of the spring sleeve 14 is provided with a step that abuts against the shielding metal plate 9. In this embodiment, when the plug and socket are separated, the spring sleeve 14 is reset into the through-hole by the action of the spring 8. The step and the shielding metal plate 9 are used to limit the contact quality between the dual pins 6 and the crown spring 11, thereby achieving stable electrical continuity. The movable layer 3 is provided with a rivet sleeve 19 that fits over the locking sleeve 7, facilitating the smooth movement of the movable layer 3 within the locking sleeve 7. The outer wall of the tightening ring 12 is provided with an external thread, and the housing 1 is provided with an internal thread. Through the screw connection between the external and internal threads, the tightening ring 12 is stably connected, easy installation and removal, and ensures the secure fixation of the shielding metal plate 9.
