Description

Technical Field

[0001] This invention belongs to the field of connector technology and relates to a detachable modular plug and its connector. Background Technology

[0002] Stage lights require separate power and signal inputs, therefore conventional lights are equipped with two sockets: one power socket and one signal socket, along with two independent wiring harnesses: a power harness and a signal harness. When connecting, as follows... Figure 6 As shown, multiple sockets need to be installed, and the cost is relatively high.

[0003] Currently, integrated sockets on the market have plugs and sockets that are combined and cannot be separated. Only one socket needs to be installed, saving installation time and reducing costs. A wiring harness is also included, and the integrated socket only requires a single plug-in. However, this structure has a problem: a single power harness can only handle a maximum power of 4.4KW, while a single lamp's power is approximately 800W. Therefore, one power harness can only power five lamps. However, the signal line has a very small load capacity, so one signal line can power all the lamps connected in series simultaneously. When the harness is connected to the sixth lamp, the signal line can continue to be connected in series, but the power line cannot. This means that conventional integrated plugs and sockets on the market are incompatible, resulting in significant limitations. Summary of the Invention

[0004] The primary technical problem to be solved by this invention is to provide a detachable, modular plug that is simple and reasonable in structure and flexible and convenient in operation, in light of the above-mentioned technical status quo.

[0005] Another technical problem to be solved by the present invention is to provide a connector that is simple and reasonable in structure and flexible and convenient in operation, in view of the above-mentioned technical status.

[0006] The technical solution adopted by the present invention to solve the above-mentioned primary technical problem is as follows: a detachable combination plug, characterized in that: the detachable combination plug is composed of a signal plug and a power plug that are detachably combined, both the signal plug and the power plug have independent wire harnesses, the front end of the signal plug is provided with a plug section that is plugged into a socket, the rear end of the signal plug is provided with a plug interface, the front end of the power plug is provided with a plug part that is plugged into the plug interface of the signal plug, and the signal plug is provided with a locking member to lock with the power plug, so that the signal plug can provide power and signal when the signal plug and the power plug are assembled together;

[0007] The rear end of the signal plug is offset from the top, and the corresponding power plug is offset from the top. The lower part of the rear end face of the signal plug is provided with an inlet hole, and the lower end of the power plug is recessed with a U-shaped groove for the signal wire to pass through.

[0008] In a further specific technical solution, the signal plug has a signal core, which fixes the signal pins and connects to the signal harness. At the same time, the signal core also fixes the power pins. The power plug has a power core, which fixes the power sleeves and connects to the power harness. When the signal plug and the power plug are assembled together, the power harness connects and communicates with the power pins fixed in the signal core through the power sleeves of the power core, and achieves electrical connection with the power pins in the signal plug.

[0009] Furthermore, the signal plug includes a cylindrical signal plug body. The front section of the signal plug body is a plug-in section that is inserted into the socket. The middle and rear sections of the signal plug body are fitted with an outer sleeve. A locking buckle is protruding on the upper surface of the plug-in section of the signal plug body near the outer sleeve, which locks after being inserted into the socket. A corresponding unlocking button is provided on the upper surface of the outer sleeve. The locking element is located on the upper surface of the outer sleeve, behind the unlocking button.

[0010] Furthermore, the surface of the main body of the signal plug is axially provided with an installation groove for mounting the locking buckle, unlocking button and locking component. Correspondingly, the upper surface of the outer sleeve is provided with a button hole and a strip hole for inserting the unlocking button and locking component. The locking buckle is installed at the front end of the installation groove and can float up and down. The locking buckle and the bottom of the installation groove are supported by a floating elastic element. The unlocking button is set in the button hole. By pressing the unlocking button, the locking buckle is moved down and retracted to release the lock.

[0011] Furthermore, the locking component is a strip plate that can be rotatably installed in the mounting groove. The rear end of the locking component has a downward protruding locking block that engages with the power plug. The front end of the power plug has a reduced-diameter insertion part that engages with the rear end of the signal plug. The upper surface of the insertion part has a locking groove for the locking block to be inserted and locked.

[0012] Furthermore, the locking component has a rotating shaft protruding on the left and right sides of the middle part, and corresponding shaft holes are provided on both sides of the inner wall of the mounting groove. The locking component can be installed in the mounting groove by rotating up and down at a certain angle through the rotating shaft. The front part of the upper surface of the locking component is formed with concave and convex ribs that are easy to press by hand. The front side of the lower surface of the locking component is supported by a reset elastic element between it and the mounting groove of the signal plug body, so that the locking component has the tendency to always lock with the power plug.

[0013] The technical solution adopted by the present invention to solve the above-mentioned other technical problem is: a connector, which includes a plug and a matching socket to realize the connection of power supply and signal, characterized in that the plug adopts any of the above-mentioned detachable combination plugs, and the socket has a lock hole on the top of its own plug interface inner wall.

[0014] Compared with existing technologies, the advantages of this invention are: the signal plug and power plug are designed to be both detachable and integrated. This allows for easy replacement of the power plug with a new one and integration into the existing signal plug in case of power overload, thus expanding the application range. The invention also features a simple and reasonable structural design, flexible and convenient operation, significantly saving installation time and costs, and greatly reducing the workload for workers.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1-5As shown, a connector includes a detachable combination plug A and a matching socket, enabling simultaneous power and signal connection, suitable for installation on current stage lights. The detachable combination plug A is detachably assembled from a signal plug 1 and a power plug 2, each with its own independent wiring harness. The signal plug 1 has a signal core 13, which secures a signal pin 14 for connection to the subsequent signal wiring harness. The signal core 13 also secures a power pin 15, typically arranged parallel to the signal pin 14. The front end of the signal plug 1 has a plug section 114 for insertion into the socket, and the rear end has a connector 112. The front end of the power plug 2 has a plug portion 21 that mates with the connector 112 of the signal plug 1. The power plug 2 has a power core 25, which secures a power sleeve 24 for connection to the subsequent power wiring harness. The signal plug 1 has a locking element 3 to lock it together with the power plug 2. When the signal plug 1 and the power plug 2 are assembled together, the power harness is connected and communicated with the power pin 15 of the signal core through the power sleeve 24 of the power core, and is electrically connected with the power pin 15 in the signal plug 1. In this way, the detachable combination plug A can provide power and signal at the same time through the signal plug 1.

[0024] The specific structure is as follows: the signal plug 1 includes a cylindrical signal plug body 11. The front section of the signal plug body 11 is a plug-in section 114 that is plugged into the socket. The middle and rear sections of the signal plug body 11 are fitted with an outer sleeve 12. A locking buckle 4 is protruding on the upper surface of the plug-in section 114 of the signal plug body 11 near the outer sleeve, which is locked after being plugged into the socket. A corresponding unlocking button 5 is provided on the upper surface of the outer sleeve 12. The locking element 3 is located on the upper surface of the outer sleeve 12 and behind the unlocking button 5. The upper surface of the signal plug body 11 is axially provided with a mounting groove 111 for mounting the locking buckle 4, the unlocking button 5, and the locking member 3. Correspondingly, the upper surface of the outer sleeve 12 is provided with a button hole 121 and a strip hole 122 for inserting the unlocking button 5 and the locking member 3. The locking buckle 4 can be installed up and down at the front end of the mounting groove 111. The locking buckle 4 and the bottom of the mounting groove 111 are supported by a floating spring, so that the locking buckle 4 always maintains an upward tendency to cooperate with the lock hole on the socket for locking. The unlocking button 5 is located in the button hole 121. By pressing the unlocking button 5, the locking buckle 4 is moved down and retracted, thereby disengaging from the lock hole on the socket and releasing the lock.

[0025] The locking element 3 is a strip plate that can be rotatably installed in the mounting groove 111. The rear end of the locking element 3 has a downward protruding locking block 31 that engages with the power plug 2. The front end of the power plug 2 has a reduced-diameter insertion part 21 that engages with the rear end of the signal plug 1. The upper surface of the insertion part 21 has a recessed locking groove 22 for the locking block 31 to be inserted and locked. The middle left and right sides of the locking element 3 have protruding pivots 32. The inner walls of the mounting groove 111 have corresponding pivot holes on both sides. The locking element 3 can be rotatably installed in the mounting groove 111 by rotating up and down at a certain angle through the pivots 32. The front part of the upper surface of the locking element 3 has a raised and recessed rib 33 for easy pressing by hand. The front side of the lower surface of the locking element 3 is supported by a return spring between it and the mounting groove 111 of the signal plug body 11, so that the locking element 3 tends to always lock with the power plug 2.

[0026] The rear connector 112 of the signal plug 1 is designed to be offset near the top. Correspondingly, the plug part 21 of the power plug 2 is offset near the top. The lower part of the rear face of the signal plug 1 is provided with a wire inlet hole 113 to facilitate the connection of the signal pins fixed in the signal core with the subsequent signal harness. The lower end of the power plug 2 is provided with a U-shaped groove 23 for the signal harness to pass through.

[0027] The matching socket and the keyhole on the socket are standard knowledge.

[0028] When connecting stage lights, such as Figure 7 As shown, five lamp bodies are connected in series with the detachable combination connector. When the sixth lamp body is connected, the power plug 2 is removed, a new power plug 2 is pulled from the distribution cabinet and assembled into the existing signal plug 1 to form a detachable combination plug A. This is then plugged into the matching socket, and the connection is continued. When the eleventh lamp body is connected, the power plug 2 can be removed again, a new power plug 2 can be pulled from the distribution cabinet and assembled into the existing signal plug 1 to form another detachable combination plug A. This is then plugged into the matching socket, and the connection is continued, repeating this process.

[0029] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
