Description

Technical Field

[0001] This invention relates to the plug of a XLR connector and related XLR connector technologies. Background Technology

[0002] XLR connectors are products from over 50 years ago and have remained so to this day. Initially, they did not have a waterproof design; for example, XLR connectors produced by a certain brand company did not have a waterproof structure.

[0003] However, with the development of technology and the continuous improvement of living standards, in some outdoor audio and video playback scenarios, due to frequent rain, snow or wading, a large number of customers have a need for high waterproof rating of IP67. For this reason, the technical staff have worked hard and developed waterproof XLR connectors with waterproof function, which are widely used in outdoor scenarios.

[0004] Because in many situations, plugs and sockets still need to be compatible with older, non-waterproof products, the structure is greatly limited. Waterproof XLR connectors can only be connected to their own sockets and cannot be connected to older XLR connectors that are not waterproof, which makes them inconvenient to use. Simply replacing the old XLR connectors would also result in waste.

[0005] Currently, the highest waterproof rating on the market is only IP65. Summary of the Invention

[0006] The primary technical problem to be solved by this invention is to provide a waterproof XLR connector plug that addresses the limitations of existing technology. The added waterproof mechanism has two adjustable positions. Normally, it is compatible with waterproof sockets. When it needs to be compatible with older, non-waterproof sockets, it can also be compatible by simply rotating and pulling the locking sleeve. This can greatly fill the market demand for highly waterproof XLR connectors.

[0007] Another technical problem to be solved by the present invention is to provide a related waterproof XLR connector in contrast to the prior art.

[0008] The technical solution of this invention to solve the primary technical problem is: a waterproof XLR connector plug, comprising:

[0009] A plug body, comprising a plug housing and an inner core and wire clamp disposed within the plug housing;

[0010] A locking button is located on the plug housing and can float up and down to lock or unlock with the matching socket.

[0011] Its characteristic is that it also includes:

[0012] A waterproof ring can be moved back and forth and fits onto the plug housing, and can be elastically deformed and connected to the locking key;

[0013] A front annular sealing ring is embedded and fixed on the front bottom or front surface of the waterproof ring sleeve, and cooperates with the outer peripheral surface of the socket or the annular groove around the outer periphery of the socket to achieve a seal;

[0014] A rear annular sealing ring is embedded and fixed on the rear outer circumferential surface of the plug housing, and cooperates with the rear bottom surface of the waterproof ring to achieve a seal;

[0015] An L-shaped guide groove and a positioning groove behind the straight section of the L-shaped guide groove are provided on the rear side of the rear annular sealing ring of the plug housing.

[0016] There is also a ring-shaped locking block sleeve that fits onto the plug housing and can push the waterproof ring sleeve to move back and forth. The locking blocks inside the locking block sleeve cooperate with the L-shaped guide groove and the positioning groove to position and lock.

[0017] Furthermore, the upper surface of the plug body has an axially oriented mounting groove, and the locking key has a locking element and a button that can float up and down. The locking element is arranged in the mounting groove, the front part of the locking element has a locking buckle that engages with the locking groove of the socket, and the rear part of the locking element is connected to the button to form a single piece.

[0018] Furthermore, the waterproof ring consists of an inner sleeve and an outer sleeve. The inner sleeve is made of metal and has a long through hole on its upper surface to expose the button at the rear of the locking component. The outer sleeve is made of plastic and is wrapped around the inner sleeve. A button part that can elastically deform and protrude is formed corresponding to the button position and is fitted onto the button.

[0019] Furthermore, the rear section of the mounting groove has upwardly extending guide edges on both sides.

[0020] Furthermore, the mounting groove is constructed by opening a mounting hole in the upper part of the plug housing and lining the inner core inside the plug housing. In addition, a side-lying U-shaped metal contact extends through the outer surface of the inner core into the mounting groove to become an elastic element, allowing the locking key to float up and down.

[0021] Furthermore, the inner rear end of the waterproof ring sleeve has an annular stepped surface, and correspondingly, the inner front end of the locking block sleeve has an outwardly protruding ring for engagement.

[0022] Furthermore, the locking key has a locking element and a button that can float up and down, and the waterproof ring has an inner sleeve and an outer sleeve, with the outer sleeve covering and composited over the inner sleeve, forming an annular stepped surface on the inner rear end of the waterproof ring.

[0023] Finally, the annular locking block sleeve has multiple ribs and / or a wrench portion distributed circumferentially on its surface.

[0024] The technical solution of the present invention to solve another technical problem is: a waterproof XLR connector, which includes a plug and a socket that are mutually plugged and locked together, the socket having a plug interface for plug insertion, and a locking groove provided on the upper inner wall of the plug interface, characterized in that the plug is any of the plugs described above.

[0025] Compared with the prior art, the beneficial effects of this invention are: it provides a high waterproof connector with IP67 rating, and the added waterproof mechanism has two adjustable positions. Normally it is compatible with IP67 sockets. When it needs to be compatible with older non-waterproof sockets, it can also be compatible by rotating and pulling the locking sleeve. This can greatly meet the market demand for high waterproof XLR connectors. The overall structure is reasonable, and the conversion and use are convenient and quick, and it is compatible with the application requirements of new and old connectors.

[0033] Figure 8 This is a schematic diagram of the plug of the waterproof XLR connector of the present invention. Detailed Implementation

[0034] like Figures 1-8The diagram illustrates a waterproof XLR connector, comprising a plug A and a socket B that interlock and lock together. The socket B has a connector 1b for plug A to be inserted into, with a locking groove 2b on the upper inner wall of the connector 1b. The plug A has a plug body, a locking key 2, and other main components. The plug body is surrounded by a plug housing 1, typically made of metal. Inside the plug housing 1 are an inner core 3, a wire clamp 4, and a tail sleeve 5 detachably threaded together. The upper surface of the plug housing 1 has an axially oriented mounting groove 11. The locking key 2 is located in the mounting groove 11 on the plug housing 1 and can move up and down to engage with the connector. The locking and unlocking of the socket B is a conventional design. The improvement of this invention lies in the presence of a waterproof ring 6, which can be moved back and forth and fits onto the plug housing 1. It is made of plastic and can be moderately elastically deformed. It is connected to the locking key 2. In this way, the front annular sealing ring 8 can be embedded and fixed on the front bottom surface of the waterproof ring 6, and cooperate with the outer peripheral surface of the plug interface 1b of the matching socket B to achieve a seal. Of course, the front annular sealing ring 8 can also be embedded and fixed on the front of the waterproof ring 6, and cooperate with the annular groove 3b around the outer periphery of the plug interface 1b of the matching socket B to achieve a similar seal. The rear annular sealing ring 9 is embedded and fixed on the rear outer circumferential surface of the plug housing 1, and seals with the rear bottom surface of the waterproof ring sleeve 6. This achieves a sealed connection between the socket B and the plug A, providing a waterproof effect. An L-shaped guide groove 12 and a positioning groove 13 behind the straight section of the L-shaped guide groove 12 are located on the rear side of the rear annular sealing ring 9 of the plug housing 1. The L-shaped guide groove 12 is typically composed of a circumferential section and a straight section, and is fitted with an annular locking block sleeve 7. A locking block 71 is located inside the locking block sleeve 7. The locking block sleeve 7 is typically made of elastically deformable plastic, allowing it to be rotated and fitted onto the plug housing 1. The locking block 71 inside the locking block sleeve 7 engages with the L-shaped guide groove 12 and the positioning groove 13 for positioning and locking, thus pushing the waterproof ring sleeve 6 to move back and forth, allowing the plug A to be plugged into different types of sockets B.

[0035] The specific structure is as follows: Figure 7 The mounting groove 11 has a mounting hole on the upper part of the plug housing 1, and the inner core 3 is lined inside the plug housing 1, thus constructing a mounting groove structure. A side-lying U-shaped metal contact 10 extends through the outer surface of the inner core 3 into the mounting groove 11, becoming an elastic element that can cooperate with the locking key 2, giving it a floating property. The rear section of the mounting groove 11 has upward-extending guide edges 14 on both sides, providing better guidance and protection for the locking key 2. The locking key 2 has a locking element 21 and a button 22. The locking element 21 can float up and down. The locking element 21 is arranged in the mounting groove 11 and is made of metal to improve strength and extend service life. The front part of the locking element 21 has a locking latch 23 that cooperates with the locking groove 2b of the socket. Figure 3The rear of the locking element 21 is connected to the button 22, and can be made into a single unit for easy installation. The waterproof ring 6 consists of an inner sleeve 61 and an outer sleeve 62. The inner sleeve 61 is made of metal and has a long through hole 64 on its upper surface, allowing the button 22 at the rear of the locking element 21 to be exposed. The outer sleeve 62 is made of plastic and is wrapped around the inner sleeve 61. A flexible, protruding button part 63 is formed at the corresponding button position, which fits onto the button 22 to achieve a complete seal and connect the locking button 2 and the waterproof ring 6. The inner rear end of the waterproof ring 6 has an annular stepped surface 65, which is formed by the outer sleeve 62 wrapping around the inner sleeve 61. Correspondingly, the inner front end of the locking block sleeve 7 has an outwardly protruding ring 72 for cooperation, thereby completing the connection between the waterproof ring 6 and the locking block sleeve 7. See [link to relevant documentation]. Figure 4 Finally, to facilitate the rotation of the locking block sleeve 7, the annular locking block sleeve 7 has multiple ribs 73 and / or a wrench portion 74 distributed circumferentially on its surface.

[0036] When using it, such as Figure 6 For sockets B without a waterproof structure similar to those of other brands, plug A of this application, after rotating the locking sleeve 7 into place and then pulling it back, allows the inner locking blocks 71 of the locking sleeve 7 to slide through the L-shaped guide grooves 12 and finally lock into the positioning groove 13. Simultaneously, the rearward movement of the locking sleeve 7 allows the waterproof ring 6 to also move backward, enabling it to be connected with such sockets. When connected with a non-waterproof socket, the waterproof ring 6 is positioned at the rear of plug A. Figure 5 For socket B with a waterproof structure, simply rotate the locking block sleeve 7 into place. That is, the inner locking block 71 of the locking block sleeve 7 rotates to the L-shaped guide groove 12 and is finally locked in the straight section of the L-shaped guide groove 12, rather than locked in the positioning groove 13. Since the locking block sleeve 7 cannot move backward, it can be used with this type of waterproof socket for plug-in connection and achieve the IP67 high waterproof requirement. That is, when using with a waterproof socket, the waterproof ring sleeve 6 is in front of the plug A.
