[0033] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0034] As Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the double-core connector includes a first single-core plug 1 and a second single-core plug 2. The first single-core plug 1 and the second single-core plug 2 are arranged in parallel. Here, the so-called parallel arrangement means that both ends of the first single-core plug 1 are flush with both ends of the second single-core plug 2. The first single-core plug 1 and the second single-core plug 2 are detachably connected by a first locking member 3.

[0035] In this embodiment, the above solution can be further optimized as follows:

[0036] As Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 shown, the first locking member 3 includes a groove 310 provided on the second single-core plug 2 and a latch assembly 320. Among them, the latch assembly 320 is provided on the first single-core plug 1 and can be stuck in the groove 310. Through the cooperation of the latch assembly 320 and the groove 310, the detachable connection between the first single-core plug 1 and the second single-core plug 2 is realized.

[0037] As Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 shown, in order to ensure the overall stability after the first single-core plug 1 and the second single-core plug 2 are connected by the first locking member 3, a first mating plane is provided on the surface of the first single-core plug 1, and a second mating plane is provided on the surface of the second single-core plug 2. The second mating plane is located on the right side of the second single-core plug 2, while the first mating plane is located on the left side of the first single-core plug 1. The groove 310 is provided on the second mating plane of the second single-core plug 2, and the latch assembly 320 is provided on the first mating plane of the first single-core plug 1. When the first single-core plug 1 and the second single-core plug 2 are connected through the combined action of the latch assembly 320 and the groove 310, the first mating plane is in close contact with the second mating plane.

[0038] As Figure 4 shown, the latch assembly 320 includes a screw 321, a locking block 322, a first return spring 323 and a base 324. Among them, the base 324 is fixed on the first mating plane of the first single-core plug 1. A first through hole is provided on the base 324 along a direction parallel to the first mating plane. One end of the screw 321 passes through the first through hole and is fixedly connected to the locking block 322. In the attached drawings of this embodiment, the locking block 322 is located above the base 324, and the screw 321 is arranged below the base 324. The first return spring 323 is arranged between the locking block 322 and the base 324, and both ends of the first return spring 323 respectively abut against the locking block 322 and the base 324. The number of the first return springs 323 is at least two.

[0039] As shown Figure 4 , Figure 6 In the figure, the locking block 322 is provided with a wedge-shaped protrusion 3221 on the end face far away from the base 324, and a card slot 311 into which the wedge-shaped protrusion 3221 is inserted is arranged in the groove 310. When the first single-core plug 1 and the second single-core plug 2 are connected by the first locking member 3, the wedge-shaped protrusion 3221 on the locking block 322 is located in the card slot 311, and the end face of the base 324 far away from the locking block 322 is closely attached to the wall surface of the groove 310 opposite to the card slot 311. When the wedge-shaped protrusion 3221 is inserted into the card slot 311, the first single-core plug 1 and the second single-core plug 2 are connected together.

[0040] As shown Figure 4 In the figure, the height at which the wedge-shaped protrusion 3221 is inserted into the card slot 311 is H1, and the compression height between the locking block 322 and the base 324 is H2. H1 is less than H2. In order to facilitate the wedge-shaped protrusion 3221 to enter the groove 310, the height of the side of the wedge-shaped protrusion 3221 close to the first single-core plug 1 is greater than the height of the side far away from the first single-core plug 1.

[0041] As shown Figure 1 , Figure 3 , Figure 4 , Figure 7 , Figure 8 In the figure, in addition, the double-core connector further includes an unlocking member 4 for pushing the wedge-shaped protrusion 3221 out of the card slot 311. Among them, the unlocking member 4 includes an unlocking pressing block 410 and a button 420. The unlocking pressing block 410 is arranged in the card slot 311. A second through hole is arranged in the card slot 311 in the direction of pushing the wedge-shaped protrusion 3221, that is, a second through hole is arranged in the card slot 311 in the compression height direction between the locking block 322 and the base 324. A connecting column 421 on one side of the button 420 passes through the second through hole and is connected to the unlocking pressing block 410.

[0042] As shown Figure 4 , Figure 8 In the figure, the unlocking member 4 further includes a second return spring 430. A trapezoidal groove is arranged at one end of the second through hole close to the button 420. The second return spring 430 is sleeved on the connecting column 421 and is arranged in the trapezoidal groove. One end of the second return spring 430 is in contact connection with the bottom surface of the trapezoidal groove, and the other end of the second return spring 430 is in contact connection with the button 420.

[0043] When the button 420 is pressed, the button 420 moves downward, causing the unlocking pressing block 410 to move downward, and the first return spring 323 is compressed. During the downward movement of the unlocking pressing block 410, the unlocking pressing block 410 will first contact the wedge-shaped protrusion 3221 on the locking block 322. As the unlocking pressing block 410 continues to move downward, the locking block 322 follows and moves downward under the action of the unlocking pressing block 410 until the wedge-shaped protrusion 3221 on the locking block 322 completely disengages from the card slot 311. During this process, the second return spring 430 is compressed. After the wedge-shaped protrusion 3221 completely disengages from the card slot 311, the first single-core plug 1 and the second single-core plug 2 can be separated. The height H1 at which the wedge-shaped protrusion 3221 is inserted into the card slot 311 is less than the stroke distance of the unlocking pressing block 410. When it is necessary to assemble the first single-core plug 1 and the second single-core plug 2 together, align the locking block 322 on the first single-core plug 1 with the groove 310 on the second single-core plug 2, and forcefully squeeze the first single-core plug 1 and the second single-core plug 2. Due to the action of the wedge-shaped protrusion 3221, the locking block 322 will move downward until both the locking block 322 and the wedge-shaped protrusion 3221 can be simultaneously inserted into the groove 310. During this process, the second return spring 430 is compressed. Continue to squeeze the first single-core plug 1 and the second single-core plug 2, and the wedge-shaped protrusion 3221 will move to face the card slot 311. At this time, the wedge-shaped protrusion 3221 will be inserted into the card slot 311 under the action of the second return spring 430.

[0044] As Figure 7 , Figure 8 shown, a positioning block 210 is further provided on the second single-core plug 2. A notch 312 is provided on one side of the groove 310. The positioning block 210 is detachably arranged in the notch 312. In this embodiment, the positioning block 210 is connected to the second single-core plug 2 through a positioning pin 5, that is, the positioning block 210 is fixed in the notch 312 through the positioning pin 5. Of course, the positioning block 210 can be further fixed by using a cross-recessed pan head screw. The addition of the positioning block 210 makes the groove 310 form a four-sided rectangular hole.

[0045] As Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, the double-core connector further includes a second locking member 7 for locking the double-core socket 6. The second locking member 7 includes a first clamping plate 710 and a second clamping plate 720. The first clamping plate 710 is movably connected to one side of the first single-core plug 1 away from the second single-core plug 2 by a pan-head screw 730. Here, the so-called movable connection means that the first clamping plate 710 can rotate around the pan-head screw 730. The second clamping plate 720 is movably connected to one side of the second single-core plug 2 away from the first single-core plug 1 by a pan-head screw 730. Here, the so-called movable connection means that the second clamping plate 720 can rotate around the pan-head screw 730. Preferably, the first clamping plate 710 and the second clamping plate 720 are symmetrically arranged. A first hanging groove for locking the double-core socket 6 is provided on the first clamping plate 710, and a second hanging groove 721 for locking the double-core socket 6 is provided on the second clamping plate 720. That is, the first single-core plug 1 and the second single-core plug 2 can be connected to the double-core socket 6 through the first clamping plate 710 and the second clamping plate 720.

[0046] A first tongue-shaped locking piece is further provided on the first clamping plate 710, and a first protrusion convenient for the first tongue-shaped locking piece to hook is provided on the double-core socket 6. When the first clamping plate 710 rotates around the pan-head screw 730, the first tongue-shaped locking piece on the first clamping plate 710 can hook the first protrusion on the double-core socket 6, and the first tongue-shaped locking piece on the first clamping plate 710 can be disengaged from the first protrusion on the double-core socket 6. If it is hooked, the connection between the first single-core plug 1 and the double-core socket 6 can be realized. If it is disengaged, the release between the first single-core plug 1 and the double-core socket 6 can be realized; a second tongue-shaped locking piece 722 is further provided on the second clamping plate 720, and a second protrusion 610 convenient for the second tongue-shaped locking piece 722 to hook is provided on the double-core socket 6. When the second clamping plate 720 rotates around the pan-head screw 730, the second tongue-shaped locking piece 722 on the second clamping plate 720 can hook the second protrusion 610 on the double-core socket 6, and the second tongue-shaped locking piece 722 on the second clamping plate 720 can be disengaged from the second protrusion 610 on the double-core socket 6. If it is hooked, the connection between the second single-core plug 2 and the double-core socket 6 can be realized. If it is disengaged, the release between the second single-core plug 2 and the double-core socket 6 can be realized. Both the first tongue-shaped locking piece and the second tongue-shaped locking piece 722 are made of elastic materials.

[0047] When it is necessary to insert the second single-core plug 2 and the first single-core plug 1 into the double-core socket, first, the second single-core plug 2 and the first single-core plug 1 are separately passed through a narrow space (such as passing through one or two smaller holes), then the first single-core plug 1 is radially mounted on the second single-core plug 2, and then the second locking member 7 is used to realize the connection between the second single-core plug 2, the first single-core plug 1 and the double-core socket 6.
