Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to an industrial connector assembly structure. Background Art

[0002] A connector is a combination of a plug and a socket that is used in conjunction with it. After the plug and socket of the connector are connected, the circuit signals at both ends are connected. In the industrial system, different connectors are used according to the corresponding application scenarios. For example, in some industrial dusty environments, the connector needs to be dustproof.

[0003] Industrial connectors are generally dustproof and moisture-proof, ensuring that the conductive sheet will not be directly exposed to dust (especially metal dust) or water vapor (humid environment) in the air. However, the prerequisite is that the male plug of the connector is inserted into the inside of the female plug. However, in actual applications, in order to ensure the safety of equipment maintenance, the two ends of the connecting line are generally powered off. At this time, the conductive sheet of the female plug of this connector without a protective conductive sheet structure will be directly exposed. It is easy to cause the conductive sheet of the female plug to be stained with dust, which may cause poor contact or short circuit failure. Therefore, during maintenance, the staff generally wrap the female plug part with an additional seal. This connector structure is inconvenient to maintain and has great safety hazards.

[0004] In addition to the above female plugs without protective connectors, some connectors with protective female plug conductive sheets are also available on the market; external threads are set on the front end of the female plug. When the female plug is not in use, the sealing cover is threadedly connected to the outside of the female plug, and the conductive sheet of the female plug is wrapped by the sealing cover. When the female plug needs to be used, the sealing cover is loosened; this threaded sealing cover structure has a very good sealing effect, but each maintenance and plug connection requires the sealing cover to be operated, which is inconvenient; and the sealing cover is not integrated on the female plug or the male plug, and is easy to lose.

[0053] The surface of the elastic component is coated with an insulating coating; the sealing plate C6 is also made of insulating material; a cable is fixed inside the male plug main housing A, and the wire cores of the cable are electrically connected to the corresponding spring conductive strips F2. Similarly, a cable is also arranged inside the female plug E, and each wire core of the cable is electrically connected to the conductive metal strip E5.

[0054] After the plug body B is pulled out from the female socket, the elastic force of the elastic component drives the main shaft C3 to rotate, and the rotation of the main shaft C3 produces two actions. The first is that the cam portion C302 is separated from the conductive contact F3; the support plate F301 at the bottom of the conductive contact F3 is pressed tightly against the place outside the cam portion C302 on the main shaft C3, and the elastic force of the spring conductive strip F2 causes the conductive contact F3 to be pulled downward from the plug hole B1; so that the sealing plate C6 can pass between the conductive contact F3 and the plug hole B1;

[0055] The second is: the elastic component pushes the sealing plate C6 to slide along the guide surface B301 until one end of the sealing plate C6 is inserted into the baffle positioning groove B301a for positioning; the other end of the sealing plate C6 is pushed upward by the elastic component to be tightly positioned on the guide surface B301, so that the sealing plate C6 is sealed on the plug hole B1, forming a seal for the plug hole B1;

[0056] When the plug body B is inserted into the female socket, the cam groove E3 pushes the main stop bar C5 to flip, causing the main shaft C3 to rotate; the main shaft C3 rotates to overcome the elastic force of the elastic component, and pulls the sealing plate C6 out to a position misaligned with the plug hole B1. At the same time, the cam portion C302 pushes the conductive contact piece F3 upward, so that the conductive contact piece F3 extends from the plug hole B1 and is connected to the conductive metal strip E5.

[0057] As a preferred embodiment of the present invention, both sides of the plug body B are provided with round holes B8; both ends of the main shaft C3 respectively pass through the round holes B8 and extend to the outside of the plug body B; both left and right inner walls of the female jack are provided with side grooves E2; the width of the side groove E2 is equal to the diameter of the main shaft C3; the cam groove E3 is provided on the surface of the side groove E2; a stopper limit groove E301 is provided at the end of the cam groove E3; a wedge-shaped surface E302 is provided between the stopper limit groove E301 and the cam groove E3;

[0058] The female plug-in E can be selected to be spliced ​​with two shells and fixed by screw connection, thereby reducing the difficulty of forming the slot hole inside the female jack.

[0059] The width of the cam groove E3 is greater than the total length of the main stop bar C5, and the width of the stop bar limiting groove E301 needs to be greater than or equal to the width of the main stop bar C5 to prevent it from getting stuck; when the plug body B is inserted into the female socket, the two ends of the main shaft C3 are respectively inserted into the side grooves E2 on both sides; and the main stop bar C5 slides in from the cam groove E3; during the insertion process of the plug body B, after the main stop bar C5 contacts with the wedge surface E302, the wedge surface E302 pushes the main stop bar C5, so that the main shaft C3 rotates, until the main stop bar C5 enters the stop bar limiting groove E301, and under the limitation of the stop bar limiting groove E301, the main stop bar C5 cannot swing; in this structure, the action of inserting the plug body B into the female socket, using the wedge surface E302 to push the main stop bar C5 and the stop bar limiting groove E301 to limit the main stop bar C5, can automatically drive the main shaft C3 to rotate and position, and the connection is more convenient;

[0060] Through the cooperation of the main shaft C3, the cam portion C302 and the elastic component, the sealing plate C6 and the conductive contact piece F3 can be extended alternately in an orderly manner, thereby improving the movement stability of the sealing plate C6 and the conductive contact piece F3 and making the use of the connector more stable.

[0062] After the main stop bar C5 extends into the stop bar limiting groove E301, the hook portion C501 is clamped into the hook groove E301a; since the elastic component has a restoring force on the main shaft C3, the elastic component can enable the hook portion C501 to be pressed into the hook groove E301a; after the hook portion C501 is hooked into the hook groove E301a, the plug body B can be clamped and fixed in the female jack, thereby realizing the locking and fixing of the plug body B and the female plug-in E, and the clamping power is also realized by the elastic component, so that the fixing structure of the plug body B and the female plug-in E is more concise;

[0063] The side wall of the female plug E is provided with a key slot E4; a key D is arranged in the key slot E4; a latch hole E401 connected to the hook slot E301a is arranged on the key slot E4; a latch D1 is arranged on the key D and extends into the latch hole E401; when the plug body B is unlocked from the female plug E, the key D is pressed, and the hook C501 is pushed out from the hook slot E301a through the latch D1, so that the main stop bar C5 can slide in the stop bar limiting slot E301. Then, the plug body B can be pulled out from the female plug E.

[0064] As a preferred embodiment of the present invention, rocker arms D3 are provided on both sides of the button D; a button shaft D4 is fixed between the two rocker arms D3; a connecting sleeve E1 is provided on the outer wall of the female plug-in unit E; an opening groove E101 is provided on the top surface of the connecting sleeve E1; the button shaft D4 is inserted into the interior of the connecting sleeve E1 from the opening groove E101; the button shaft D4 is rotatably connected to the connecting sleeve E1; a limiting rib D2 is provided on the side wall of the button D; a limiting convex point E402 is provided on the side wall of the button groove E4; when the button shaft D4 is rotatably connected to the connecting sleeve E1, the button D is swung by pressing the button D in a small range, and the latch D1 pushes the hook portion C501 out of the hook groove E301a; when the button D is rotated to a certain angle, the limiting rib D2 is limited by the limiting rib E402, so that the button D will not loosen from the button groove E4.

[0065] As a preferred embodiment of the present invention, the plug body B is composed of two plug shells B3; the male plug main shell A is composed of two main shell parts A1; the plug shell B3 is provided with a plug groove B2; the inner side wall of the main shell part A1 is provided with a positioning convex strip A102 matching the plug groove B2; the inner hole of the male plug main shell A matches the plug body B; the plug body B is inserted into the male plug main shell A; the positioning convex strip A102 is embedded in the plug groove B2;

[0066] Countersunk holes A101 are provided on the upper and lower sides of the main shell A1. The countersunk holes A101 on the upper and lower sides are respectively connected by two screws to fix the two main shells A1 and form a female socket; and after the positioning ridge A102 is embedded in the plug groove B2, the plug body B cannot be pulled out from the female socket, so that the plug body B and the male plug main shell A are combined into an integrated structure; and the two plug shells B3 are clamped by the female socket to form an integrated fixed structure.

[0067] As a preferred embodiment of the present invention, the inner cavity of the plug housing B3 is provided with a T-slot B6; the male plug conductor F also includes a connection seat F1; the connection seat F1 is provided with a connection seat slider F101 matching the T-slot B6; the two ends of the connection seat slider F101 are respectively inserted into the two T-slots B6;

[0068] The back of the plug housing B3 is provided with a conductive sheet slot B5 for the spring conductive strip F2 to extend out; when assembling the male plug conductor F, first insert the connecting seat slider F101 into one of the T-slots B6, then align the T-slot B6 of the other plug housing B3 with the connecting seat slider F101, and then insert the connecting seat slider F101 into the other T-slot B6, so that the connecting seat F1 is positioned on the plug body B, thereby realizing the positioning of each spring conductive strip F2 in the plug body B.

[0069] As a preferred embodiment of the present invention, a round shaft C4 is fixed to one end of the elastic component away from the sealing plate C6; a spring clip positioning seat B4 is fixed to the plug housing B3; a round shaft positioning hole B401 is provided on one end surface of the spring clip positioning seat B4; a spring clip slot B402 connected to the round shaft positioning hole B401 is provided on the side wall of the spring clip positioning seat B4; the two ends of the round shaft C4 are respectively inserted into the two round shaft positioning holes B401; the elastic component extends to the outside from the spring clip slot B402;

[0070] The length of the circular shaft C4 is greater than the width of the elastic component; the depth of the circular shaft positioning hole B401 is greater than the spring slot B402, so that after the two plug housings B3 are spliced, the two ends of the circular shaft C4 extend into the circular shaft positioning hole B401 for positioning, and the circular shaft C4 can rotate in the circular shaft positioning hole B401, which can enhance the range of motion of the elastic component and reduce the risk of overloading the elastic component.

[0071] As a preferred embodiment of the present invention, the elastic component is a spring sheet; the two ends of the spring sheet are respectively fixed to the sealing plate C6 and the circular shaft C4; a spring sheet fixing plate C301 is fixed to the shaft body of the main shaft C3; the spring sheet is fixed to the spring sheet fixing plate C301;

[0072] A through hole is opened in the middle of the spring sheet, and a bolt is passed through the through hole and then threadedly connected to the spring sheet fixing plate C301, so that the spring sheet is fixed on the spring sheet fixing plate C301;

[0073] The spring sheet can be divided into a first spring sheet C1 and a second spring sheet C2; the first spring sheet C1 is a section between the spring sheet fixing plate C301 and the round shaft C4; the second spring sheet C2 is a section between the sealing plate C6 and the spring sheet fixing plate C301; the surface of the spring sheet is sprayed with insulating material; after the spring sheet is fixed to the spring sheet fixing plate C301, the first spring sheet C1 and the second spring sheet C2 are deformed into two sections that do not interfere with each other, and the second spring sheet C2 mainly provides elastic support force for the sealing plate C6 at the free end; after the main stop bar C5 is not limited, the first spring sheet C1 is the main rotating shaft C3 provides a reset force to make the main shaft C3 rotate, and the rotation of the main shaft C3 drives the spring fixing plate C301 and the second spring sheet C2 to move, so that the sealing plate C6 slides along the guide surface 301 and is finally inserted into the baffle positioning groove B301a for positioning; the second spring sheet C2 connected to the sealing plate C6 is an elastic strip, which can elastically press the other end of the sealing plate C6 against the guide surface 301 after the sealing plate C6 is inserted into the baffle positioning groove B301a, so that the surface of the sealing plate C6 can fit on the guide surface 301, thereby enhancing the sealing effect of the sealing plate C6 in the plug hole B1.

[0074] As a preferred embodiment of the present invention, the bottom surface of the plug housing B3 is provided with an arc-shaped protrusion B7; the arc-shaped protrusion B7 is provided below the first spring sheet C1;

[0075] Since the stroke of the main shaft C3 is large, the length required for the first spring piece C1 is long, so the space required for folding the first spring piece C1 is large to ensure that the first spring piece C1 will not be overloaded. The general method is to overcome this problem by increasing the volume of the plug body B, but this will increase the volume of the plug body B and the volume of the entire connector.

[0076] In the present application, the first spring sheet C1 forms a reverse protrusion after contacting the arc-shaped protrusion B7. First, it can form multiple sections of folding, so that a longer spring sheet can be accommodated in a smaller space of the plug body B without overloading the spring, thereby preventing the spring from being over-pressurized and over-folded, resulting in scrap. Second, the total length of the first spring sheet C1 can be guaranteed. After the plug body B is loosened from the female socket, there is still sufficient elastic force to stably support the main shaft C3. The main shaft C3 has sufficient elastic reset ability to ensure the clamping force of the sealing plate C6. Third, the total volume of the plug body B can be made smaller.

[0077] The beneficial effects of the present invention are:

[0078] 1. When the plug body is pulled out from the female jack, the conductive contact piece can be automatically retracted, and the sealing plate can be automatically pushed out to seal the plug hole. The male plug can automatically cover the plug hole without additional operation when it is pulled out, which improves the dust and moisture resistance level, is safer, better protects the conductive contact piece, and is more convenient for maintenance;

[0079] 2. By inserting the plug body into the female socket, the wedge-shaped surface is used to push the main stop bar and the stop bar limit groove to limit the main stop bar, which can automatically drive the main shaft to rotate and position, thereby realizing the linkage of the sealing plate and the conductive contact piece, that is, the sealing plate is retracted first, and then the conductive contact piece is extended. There is no need to open the cover of the plug hole before use, and the male and female plugs connected thereto are more convenient and quick;

[0080] 3. After the sealing plate C6 is inserted into the baffle positioning groove, the second spring sheet can elastically press the other end of the sealing plate against the guide surface, so that the surface of the sealing plate can be in contact with the guide surface, thereby enhancing the sealing effect of the sealing plate on the plug hole;

[0081] 4. Arranging an arc-shaped protrusion in the plug body can ensure the total length of the first spring sheet, prevent the spring from being over-pressurized and over-folded, resulting in scrapping, and the total volume of the plug body can be made smaller.

[0082] The above description is only a preferred embodiment of the present invention, so all equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
