[0045] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the following further describes a quick-connect, high-reliability shielded connector of the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0046] Please refer to Figures 1-8 A quick-connect, high-reliability shielded connector includes: a socket component 100 having a connecting hole 110 with a plurality of protrusions 111 disposed therein; a plug component 200 having an insertion end extending into the connecting hole 110, the insertion end being provided with a connecting groove 210, each protrusion 111 having an adapted connecting groove 210, and the connecting groove 210 including a communicating guide groove 211 and a locking groove 212, the protrusion 111 moving along the guide groove 211 and being locked in the locking groove 212; a first shielding component 310 disposed between the outer side wall of the insertion end and the inner side wall of the socket component 100 and located outside the connecting groove 210.

[0047] The connection structure between the socket component 100 and the plug component 200 is convenient, fast, and stable. By inserting the protrusion 111 into the connection groove 210 and then rotating it into the locking groove 212 for locking, the stability of the connection between the socket component 100 and the plug component 200 is ensured. The provision of a shielding member can provide a certain shielding effect on electromagnetic signals, ensuring the normal operation of the device. Furthermore, a position for placing the shielding member is ensured between the sidewalls of the socket component 100 and the sidewalls of the insertion end, namely, a position outside the connection groove 210 at the insertion end, in the connection hole 110. The shielding member in this position, because it is located within the connection hole 110, is not affected by pressure, will not cause gaps due to imperfect axial fit, and will not affect performance due to positional offset. Multiple shielding members can be provided as needed, providing high reliability and ensuring the performance of the shielding member.

[0048] Please refer to Figure 1 and Figure 3 The conductive member includes a second shielding member 320, which is disposed within the connection hole 110. When the protrusion 111 engages with the locking groove 212, the end surface of the plug 200 and the bottom of the connection hole 110 press the second shielding member 320 tightly. As will be appreciated, an annular base 120 is typically disposed within the connection hole 110, and the inner diameter of the annular base 120 is less than or equal to the inner diameter of the plug 200. The provision of the second shielding member 320 further improves shielding performance.

[0049] Please refer to Figure 1 and Figure 3 The conductive member includes a third shielding member 330, which is sleeved onto the plug member 200. The bottom of the outer peripheral wall of the insertion end has a stepped end surface 250. When the protrusion 111 engages with the locking groove 212, the end surface of the socket member 100 and the stepped end surface 250 compress the third shielding member 330. The provision of the third shielding member 330 provides at least triple shielding between the connection between the socket member 100 and the plug member 200, further enhancing the shielding effect.

[0050] Furthermore, there is a pre-positioning or fool-proofing structure between the protrusion 111 and the connection groove 210. The pre-positioning or fool-proofing structure can facilitate the alignment, avoid poor contact, and facilitate stable contact of the terminals or other structures in the connector, and can determine the contact position in advance, reducing the design difficulty. In particular, the pre-positioning or fool-proofing structure is: further, there is one protrusion 111; or, there are multiple protrusions 111 on the same horizontal plane, and at least two of the multiple protrusions 111 on the same horizontal plane have different shapes. In particular, please refer to FIG. Figure 8 、 Figure 9 、 Figure 13 and Figure 14 , at least two protrusions 111 on the same horizontal plane have different widths, and the width of the guide groove 211 corresponds to the width of the protrusion 111 one by one; or, multiple protrusions 111 are provided on the same horizontal plane, and the angles between the multiple protrusions 111 on the same horizontal plane are different, that is, the protrusions 111 are not arranged in a circular array. In particular, please refer to Figure 8 、 Figure 10 and Figure 15 Two or more locking grooves 212 can be set at different heights. Two or more locking grooves 212 are connected to the same guide groove 211 to form more than one layer of locking grooves 212. The protrusions 111 are also set at more than one layer accordingly, thereby improving the locking force.

[0051] Please refer to 1-6, which also includes a nut 400 and a tail sleeve 410. The tail sleeve 410 is disposed within the plug 200 and has a wire-locking portion 411 extending away from the socket 100. The nut 400 is threadedly connected to the end of the plug 200 facing away from the socket 100, and the inner diameter of the wire-locking portion 411 gradually decreases as the nut 400 is tightened. The nut 400 and the wire-locking portion 411 are used to facilitate the connection of the plug module to the cable. Tightening the wire-locking portion 411 with the nut 400 gradually compresses the cable to prevent it from falling off. In particular, the wire-locking portion 411 has several spring bars arranged in a circular array. The inner diameter of the nut 400 gradually decreases as it moves away from the socket module. As the nut 400 is tightened, the aperture formed by the spring bars in the circular array gradually decreases, thereby squeezing and wrapping the cable, not only preventing the cable from loosening but also providing a sealing effect. In particular, the cross section of the elastic bar is a quadrilateral or fan-shaped structure that widens from the center to the circumference. In particular, a flexible wire clamping sleeve 420 can be provided outside the cable, and the wire locking portion 411 squeezes the wire clamping sleeve 420, and the wire clamping sleeve 420 wraps the cable. The wire clamping sleeve 420 is generally made of rubber or silicone, thereby protecting the cable and improving the sealing performance. In particular, the wire clamping sleeve 420 is also made of electromagnetic shielding material, which makes the product have a stronger electromagnetic shielding capability. In particular, please refer to Figure 5 The cable is generally provided with an overmolded plastic coating at the contact point with the cable clamp 420 to protect the cable and improve the sealing effect. Figure 6 and Figure 7 The end of the socket component 100 facing away from the plug component 200 is also connected to a cable that is overmolded and coated with rubber.

[0052] Please refer to Figure 1 and Figure 3 A fourth shielding member 340 is further provided between the plug member 200 and the tail sleeve 410. The provision of the fourth shielding member 340 can improve the shielding performance of the tail portion of the plug member 200.

[0053] Please refer to Figure 1-Figure 3 、 Figure 5 and Figures 8-18 , and also includes an outer ring 500, which can be axially moved and sleeved on the outside of the plug component 200. There is a first circumferential limiting structure between the outer ring 500 and the plug component 200, and a second circumferential limiting structure between the outer ring 500 and the socket component 100. The outer ring 500 can selectively cooperate with the first circumferential limiting structure or the second circumferential limiting structure through axial movement. Simply put, the first circumferential limiting structure and the second circumferential limiting structure are generally a card block and slot matching structure, that is, one of the outer ring 500 and the plug member 200 is provided with a first card block 220 and the other is correspondingly provided with a first card slot 520 that matches the first card block 220, and one of the outer ring 500 and the socket member 100 is provided with a second card block 510 and the other is correspondingly provided with a second card slot 130 that matches the second card block 510; it can be understood that the first buckle can be provided only on one of the plug member 200 or the outer ring 500, or can be staggered on the plug member 200 and the outer ring 500, and the first card slot 520 is provided correspondingly, please refer to Figure 3 、 Figures 8-18 The same applies to the second block 510 and the second slot 130. By setting the outer ring 500, it is possible to prevent the protrusion 111 and the locking slot 212 from accidentally touching and causing loosening. That is, before the protrusion 111 and the locking slot 212 are matched, the first circumferential limiting structure takes effect and the second circumferential limiting structure is invalid, and the outer ring 500 rotates to drive the plug component 200 to rotate; when the protrusion 111 and the locking slot 212 are matched, the second circumferential limiting structure takes effect and the first circumferential limiting structure is invalid, and the outer ring 500 cannot rotate to drive the plug component 200 to rotate. In particular, please refer to Figure 4 and Figure 16, the outer peripheral wall of the socket component 100 is provided with a plurality of second card slots 130 opening facing the plug module, and the inner wall of the outer ring 500 at one end facing the socket module is provided with a plurality of second card blocks 510 consisting of horizontal bars and vertical bars, the vertical bars are adapted to the second card slots 130, and the horizontal bars are adapted to the end face of the socket component 100; the other end of the outer ring 500 is provided with a first card slot 520 opening facing away from the socket module, and the plug component 200 is provided with a first card block 220 adapted to the first card slot 520; the outer ring 500 can be slidably sleeved on the outside of the plug component 200, so that one of the second card block 510 and the first card slot 520 plays a circumferential limiting role, that is, when the first card slot 520 is matched with the first card block 220, the second card block 510 is separated from the second card slot 130; when the second card block 510 is matched with the second card slot 130, the first card slot 520 is separated from the first card block 220. For understanding, please refer to Figure 4 、 Figures 8-18 The first slot 520 and the second slot 130 can be arranged on the outer wall or the inner wall, or can even be directly opened through the axial direction of the wall; for details, please refer to Figure 2 、 Figure 8 、 Figure 9 、 Figure 11 、 Figure 13 and Figure 14 , the second slot 130 is provided on the outer peripheral wall of the socket 100; please refer to Figure 15 The second slot 130 is provided on the inner wall of the socket 100; Figure 10 , the second slot 130 is through the peripheral wall; please refer to Figure 12 , the socket 100 is provided with a second block 510, please refer to Figure 17 The outer ring 500 is provided with a second engaging groove 130 that engages with the second engaging block 510. Simply put, the outer wall of the outer ring 500 can be provided with an anti-slip feature, typically with a concave-convex pattern or pattern, to increase friction and facilitate rotation. In particular, a retaining groove 140 can be provided outside the connecting hole 11. The front end of the outer ring 500 is inserted into the retaining groove 140, thereby improving sealing performance.

[0054] Please refer to Figure 1-Figure 3 、 Figure 4 、 Figure 16 and Figure 18, and also includes a thrust member for locking the outer ring 500 in a position where the second circumferential limit structure is activated and the first circumferential limit structure is deactivated. The thrust member comprises one of an axial elastic member, a screw, and a retaining spring. It is understood that the axial elastic member can be a spring coil 550, a spring clip, a spring coil, a spring bar, or other elastic object; the screw is generally secured radially; and the retaining spring is generally fixed to the rear end of the outer ring 500 facing away from the socket module when the second circumferential limit structure is activated. Specifically, the thrust member is a spring coil 550, disposed between the outer ring 500 and the plug assembly 200, and a clamping structure for clamping the spring coil 550 is provided between the outer ring 500 and the plug assembly 200. When the first circumferential limit structure is activated, the spring coil 550 exerts a propulsive restoring force. The clamping structure is typically a protrusion. Specifically, a first protrusion 540 is provided on the inner circumferential wall of the outer ring 500 near the socket module, and a second protrusion 240 is provided on the plug 200. The first and second protrusions 540 and 240 constrain the spring coil 550. When the first circumferential restraining structure is activated, the spring coil 550 is compressed. Specifically, when the second circumferential restraining structure is activated, the spring coil 550 still maintains a restoring force. Specifically, the first protrusion 540 is formed by a horizontal bar on the second clamping block 510. Specifically, the spring coil 550 is made of electromagnetic shielding material.

[0055] Please refer to Figure 1 、 Figure 3 、 Figure 4 and Figure 16 and Figure 18 , an anti-retraction structure is provided between the outer ring 500 and the plug component 200. The anti-retraction structure can be constructed by connection methods such as a boss snap-fit connection structure, a retaining spring connection, a metal spring connection, and a machine screw connection as needed. The boss snap-fit connection structure includes a first snap-fit member 530 and a second snap-fit member 230. The first snap-fit member 530 is provided on the inner wall of the outer ring 500, and the second snap-fit member 230 is provided on the outer wall of the plug component 200. The first snap-fit member 530 and the second snap-fit member 230 are both provided with a guide bevel for guiding the snap-fit direction. The first snap-fit member 530 and the second snap-fit member 230 are both provided with a snap-fit surface for snapping. During actual installation, the plug component 200 is inserted into the outer ring 500. At this time, the guide bevels of the first snap-fit member 530 and the second snap-fit member 230 are relative to each other. Under the action of the guiding inclined surface, the second latch 230 moves downward through the first latch 530 and reaches the bottom of the first latch 530. At this time, the fastening surfaces of the first latch 530 and the second latch 230 are relative, and the second latch 230 can no longer retreat to the top of the first latch 530, thereby installing the plug component 200 into the first hollow portion to prevent the plug from retreating. In particular, the first latch 530 and / or the second latch 230 are made of an elastic material, such as plastic, and the fastening surface can be set to a horizontal plane.

[0056] Preferably, both the socket component 100 and the plug component 200 are made of electromagnetic shielding materials.

[0057] It can be understood that the essence of electromagnetic waves is the propagation of changing electric and magnetic field oscillations in space. When electromagnetic waves propagate in a conductive medium, the amplitudes of the electric and magnetic fields decay exponentially with increasing distance. Therefore, on the surface of the conductive medium, the amplitudes of the electric and magnetic fields are the largest, and the deeper into the interior, the smaller the amplitude. As a result, the conductive medium plays a role in shielding electromagnetic field signals.

[0058] Simply put, electromagnetic shielding materials can be selected from existing materials that can achieve a certain electromagnetic shielding effect. In most cases, electromagnetic shielding materials can be made of metals such as copper, aluminum, and steel. However, for constant and extremely low-frequency magnetic fields, materials such as ferrite can also be used as electromagnetic shielding materials. In particular, the materials used to make the first shielding member 310, the second shielding member 320, the third shielding member 330, and the fourth shielding member 340 in this application are selected from materials with flexibility and electromagnetic shielding properties, such as silicone, rubber, plastic, etc., which also contain metals, that is, conductive rubber or conductive fabric. In other words, the flexible feature improves the sealing effect and prevents liquid from entering and affecting the transmission of electricity or signals.

[0059] Generally and simply, an axial guide structure, namely, an axially disposed guide rail groove structure, can be provided between the outer ring 500 and the plug member 200. The same applies to the connection between the plug member 200 and the tail sleeve 410. Specifically, a guide rail is provided on the inner wall of the outer ring 500. The guide rail is disposed on the first protrusion 540, and a corresponding groove is provided on the plug member 200. It is understood that the length of the guide rail groove is less than or equal to the axial travel of the outer ring 500.

[0060] Typically, the connector further comprises a plug core 621 and a plug terminal 620, the plug core 621 being sleeved within the plug assembly 200, the plug terminal 620 being inserted through the plug core 621, as well as a receptacle terminal 610 and a terminal fixing core 611. The receptacle 100 forms a connection hole 110, the terminal fixing core 611 being disposed at the end of the receptacle 100 away from the plug module, the receptacle terminal 610 being inserted through the terminal fixing core 611, and the receptacle terminal 610 forming a contact connection with the plug terminal 620 when the protrusion 111 engages with the locking groove 212. Due to the tight connection between the receptacle module and the plug module, the contact stability between the receptacle terminal 610 and the plug terminal 620 can also be ensured.

[0061] Simply put, the first shielding component 310 will not deviate from the range even if it moves axially because it is blocked by the protrusion 111 and the stepped end face 250 of the third shielding component 330 / plug component 200. In particular, a positioning groove can be provided on the inner wall of the insertion end or the connecting hole 110 to further limit the axial movement of the first shielding component 310.

[0062] In the description of this application, it should be noted that the terms "inside," "outside," "upper," "lower," "front," "rear," etc., indicating orientations or positional relationships, are based on the positional relationships shown in the accompanying drawings and are intended only to facilitate the description of this application and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. In this application, "axial" refers to the direction from the socket component away from or toward the plug component, while "horizontal" refers to a plane perpendicular to the axial direction. The connection described may refer to a direct connection relationship or an indirect connection relationship. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0063] In summary, the present invention provides a quick-connect, high-reliability shielded connector that forms a triple shield and seal at the connection between the socket and plug components by providing a first shielding member, a second shielding member, and a third shielding member. Due to the mating structure between the protrusion and the connection groove of the present invention, the first seal is not affected by mating clearance or mating pressure, resulting in extremely high stability, enhancing the shielding performance of the connector and making electrical and signal transmission more stable. The second and third shielding members are both stabilized by the stable connection between the protrusion and the connection groove, ensuring stable pressure and sealing gaps after extrusion, further improving shielding and sealing performance. Furthermore, the provision of a fourth shielding member at the rear of the plug further enhances sealing performance.
