Description

Technical Field

[0001] The present invention belongs to the technical field of connectors, and more specifically, relates to an integrated connector based on a self-locking regulation mechanism. Background Art

[0002] A connector is a device used to achieve electrical, mechanical, or optical connections, and is usually used to transmit signals or power between two or more circuits. The self-locking regulation mechanism refers to a mechanism designed inside the connector that can automatically lock after connection and unlock through specific operations when needed. When two connecting parts are docked, the self-locking mechanism will automatically start and lock the connection state to prevent accidental disconnection.

[0003] For example, the patent with the patent publication number CN102916281B discloses a plug electrical connector, a socket electrical connector, and an electrical connector combination. After the first conductive terminal and the second conductive terminal are combined, the fixing part at the rear end of the first shielding housing needs to be bent to fix the combination into the first shielding housing. It can neither achieve self-locking quickly after combination nor facilitate disassembly and assembly, having limitations.

[0004] Based on the above-mentioned disadvantages in the prior art, a self-locking regulation mechanism-based integrated connector is specially designed to overcome the disadvantages of the prior art, which can integrate the connection of power supply and signal lines, has high stability, the unlocking of the second connection end does not affect the installation of the first connection end, and is convenient for disassembly and assembly. Summary of the Invention

[0005] The purpose of the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a self-locking regulation mechanism-based integrated connector that can integrate the connection of power supply and signal lines, has high stability, the unlocking of the second connection end does not affect the installation of the first connection end, and is convenient for disassembly and assembly.

[0006] To solve the above technical problems, the present invention provides such a self-locking regulation mechanism-based integrated connector, which includes a first connection end and a second connection end adapted to be plugged and matched with the first connection end. Both the first connection end and the first connection end are rectangular. The second connection end is provided with a plurality of jack groups arranged in a front-back line. The first connection end is provided with a plurality of pin groups having the same number as the plurality of jack groups. The pin groups are correspondingly adapted to the jack groups one by one. Two front-back opposite wedge blocks 1 are connected to the upper side of the second connection end. The right side of the wedge block 1 is an inclined surface. The first connection end is provided with an elastic clamping member adapted to catch the wedge block 1. A sliding rod slides on the first connection end. One side of the sliding rod is connected with a wedge block 2 adapted to squeeze the elastic clamping member. The right side of the wedge block 2 is an arc surface. A pushing block is connected to the upper side of the sliding rod.

[0007] Preferably, the elastic clamping member includes a support sleeve. Two support sleeves that are opposite to each other left and right are connected to both the front and rear sides of the first connection end. A lifting rod slides on the upper part of the support sleeve. A tension spring located inside the support sleeve is connected between the lifting rod and the support sleeve. The tension spring is used to reset the upward-moved lifting rod. A limiting plate adapted to clamp the first wedge block is commonly connected between the lifting rods.

[0008] Preferably, it further includes a rotating shaft rotatably arranged between the sliding rod and the pushing block. A rotating handle adapted to be embedded in the pushing block and a limiting block located below the rotating handle and adapted to be embedded in the sliding rod are connected to the rotating shaft. The limiting block and the rotating handle extend in opposite directions. The limiting block and the second wedge block are respectively adapted to squeeze the upper and lower sides of the limiting plate.

[0009] Preferably, it further includes two connection blocks that are opposite to each other front and rear and are respectively connected to the front and rear ends of the second connection end. Two slots that are opposite to each other left and right are opened on the upper side of the connection block. A limiting slot adapted to allow the connection block to pass through is opened on the lifting rod. A clamping rod adapted to be inserted into the slot is connected to the limiting slot of the lifting rod.

[0010] Preferably, it further includes a locking assembly. Contact points for contact and cooperation with the pin group are provided in the jack group. The side of the contact point away from the pin group is adapted to be in contact and cooperation with the transmission line. A locking assembly is provided on the second connection end.

[0011] Preferably, the locking assembly includes a support block rotatably arranged on the upper part of the second connection end. The number of support blocks is the same as the number of jack groups, and the support blocks correspond to the jack groups one by one. Torsion springs located inside the second connection end are connected between the front and rear sides of the support block and the second connection end. The torsion springs are used to reset the rotated support block. A dial block and a pressing block adapted to move in the jack group are respectively connected to the upper and lower sides of the support block.

[0012] Preferably, it further includes a clamping block connected to the support block. A spring piece located on the right side of the clamping block is connected inside the second connection end. A bayonet adapted to clamp the clamping block is opened on the spring piece. A notch located above the bayonet and adapted to allow the clamping block to pass through is opened on the spring piece. The lower end of the spring piece extends into the jack group.

[0013] Preferably, two contact pieces that are opposite to each other up and down and are adapted to be in contact with the pin group are provided on the contact point in the jack group. Two convex portions that are opposite to each other left and right and protrude in the direction of mutual approach are provided on the side of the two contact pieces close to each other.

[0014] The beneficial effects that the present invention can achieve on the basis of overcoming the shortcomings of the prior art are as follows:

[0015] 1. During the process of inserting the second connection end into the first connection end, the wedge block 1 will squeeze and pass over the elastic latch. The elastic latch will reset and latch onto the wedge block 1, thereby completing self-locking synchronously during insertion and improving stability. When unlocking, the wedge block 2 is used to squeeze the limit plate to release the wedge block 1, and then the second connection end is pulled out in the direction away from the first connection end with the push block as the fulcrum, which is convenient and fast to operate.

[0016] 2. The lifting rod will drive the limit plate to move downward under the action of the reset of the tension spring to block the left side of the wedge block 1, thereby achieving self-locking after the second connection end is inserted into the first connection end by moving it to the right. This self-locking method can not only be easily unlocked by using the wedge block 2, but also prevent the wedge block 1 from being accidentally released by moving to the left, and the stability of self-locking is high.

[0017] 3. The limit plate is used to block the upper side of the limit plate to achieve safe secondary locking. Since the limit plate needs to rotate to move away from the upper side of the limit plate, and the limit plate needs to move upward to release the wedge block 1, it can prevent the phenomenon of accidental loosening during use and further improve stability.

[0018] 4. When the transmission line is inserted into the jack group, the transmission line is automatically and synchronously clamped into the jack group. If it is necessary to remove the transmission line from the jack group, hold the transmission line and rotate the dial block clockwise to move it upward. The pressure block releases the transmission line, and at this time, a pulling force can be applied to the left with the dial block as the fulcrum to remove the transmission line from the jack group, and the disassembly and assembly operations of the transmission line are convenient.

Detailed implementation manners

[0030] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0031] In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. The technical solutions of the present invention will be clearly and completely described below with reference to the drawings. It should be noted that the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0032] An integrated connector based on a self-locking control mechanism, such as Figures 1-2As shown, it includes a first connection end 1 and a second connection end 2 adapted to be plugged and mated with the first connection end 1. Both the first connection end 1 and the first connection end 1 are rectangular. The second connection end 2 is provided with a plurality of jack groups 21 arranged in a horizontal row one after another. The plurality of jack groups 21 can be power line jacks, signal line jacks, etc. respectively. The first connection end 1 is provided with a plurality of pin groups 11 having the same number as the plurality of jack groups 21. The plurality of pin groups 11 can be power line pins, signal line pins, etc. respectively. The pin groups 11 are correspondingly adapted to the jack groups 21 one by one. Plugging the second connection end 2 onto the first connection end 1 can connect the jack groups 21 and the pin groups 11. Two opposite wedges 22 are connected to the upper side of the second connection end 2. The right side of the wedge 22 is an inclined surface. The first connection end 1 is provided with an elastic clamping member 3 adapted to clamp the wedge 22. During the process of the second connection end 2 being plugged into the first connection end 1 by moving rightward, the second connection end 2 will drive the wedge 22 to move rightward and squeeze the elastic clamping member 3. The elastic clamping member 3 deforms until the wedge 22 continues to move rightward and crosses the elastic clamping member 3. Then the elastic clamping member 3 will reset and clamp the wedge 22, thereby completing self-locking synchronously during plugging and improving stability. A sliding rod 41 slides on the first connection end 1. One side of the sliding rod 41 is connected with a wedge 42 adapted to squeeze the elastic clamping member 3. The right side of the wedge 42 is an arc surface. A pushing block 43 is connected to the upper side of the sliding rod 41. When it is necessary to disassemble the second connection end 2 from the first connection end 1, hold the second connection end 2 by hand and move the pushing block 43 rightward. The pushing block 43 will drive the wedge 42 to move rightward through the sliding rod 41 and squeeze the elastic clamping member 3, thereby loosening the elastic clamping member 3 from the wedge 22. At this time, a thrust can be applied rightward with the pushing block 43 as a fulcrum, and the second connection end 2 can be moved leftward to disassemble it from the first connection end 1, thus saving steps such as manually pressing and unlocking in an extra direction. Then, with the pushing block 43 as a fulcrum, the second connection end 2 can be conveniently and easily pulled out in a direction away from the first connection end 1. And since the pushing block 43 drives the sliding rod 41 to move rightward to a threshold value, the sliding rod 41 will resist the first connection end 1 rightward to prevent the first connection end 1 from being driven to move leftward, thereby also avoiding the influence of the disassembly of the second connection end 2 on the installation of the first connection end 1.

[0033] As Figures 2-5As shown, the elastic clamp 3 includes a support sleeve 31, and two left and right opposite support sleeves 31 are connected to the front and rear sides of the first connection end 1. A lifting rod 32 is slidably provided on the upper part of the support sleeve 31. A tension spring 33 located in the support sleeve 31 is connected between the lifting rod 32 and the support sleeve 31. The tension spring 33 is used for resetting the lifting rod 32 that moves upward. A limit plate 34 suitable for clamping the wedge block 22 is commonly connected between the lifting rods 32. When the wedge block 22 moves to the right, it will squeeze the lower side of the limit plate 34 and lift the limit plate 34 to move upward. The limit plate 34 will drive the lifting rod 32 to move upward, and the tension spring 33 will deform. When the wedge block 22 moves to the right, the limit plate 34 will push the lifting rod 32 to move upward. After the wedge block 22 continues to move right and passes over the limit plate 34, the tension spring 33 is reset, and the lifting rod 32 will drive the limit plate 34 to move down and block the left side of the wedge block 22 under the action of the tension spring 33, so that the second connecting end 2 is moved right and plugged into the first connecting end 1 for self-locking. When unlocking, the rightward movement of the wedge block 2 42 will squeeze the lower side of the limit plate 34 and lift the limit plate 34 to move upward. At this time, the wedge block 22 can move left away from the limit plate 34. After releasing the wedge block 2 42, the limit plate 34 will move down and reset under the action of the tension spring 33, and squeeze the wedge block 2 42 to make it move left and reset.

[0034] like Figure 2 and Figure 4 As shown, it also includes a rotating shaft rotatably arranged between the slide bar 41 and the pushing block 43, the rotating shaft is connected with a rotating handle 44 suitable for being embedded in the pushing block 43 and a limiting block 45 located below the rotating handle 44 and suitable for being embedded in the slide bar 41, the limiting block 45 and the rotating handle 44 extend in opposite directions, the limiting block 45 and the wedge block 42 are respectively suitable for squeezing the upper and lower sides of the limiting plate 34, when the second connecting end 2 is plugged into the first connecting end 1, the limiting block 45 is used to block the upper side of the limiting plate 34, so as to perform a safe secondary locking, because the limiting block 4 5 needs to be rotated to be moved away from the upper side of the limiting plate 34, and the limiting plate 34 needs to be moved upward to release the wedge block 1 22, so that the phenomenon of accidental loosening during use can be prevented, and the stability is further improved; when unlocking, it is only necessary to press the handle 44 to the right before moving the push block 43 to the right, so that the handle 44 drives the limiting block 45 to rotate clockwise through the rotating shaft and move away from the upper side of the limiting plate 34, and then continue to move the push block 43 to the right to make the wedge block 2 42 squeeze the limiting plate 34, so that the secondary continuous unlocking of the wedge block 1 22 can be cleverly completed in one step.

[0035] like Figure 2 and Figure 5As shown in the figure, it further includes two front and rear opposite connecting blocks 51 respectively connected to the front and rear ends of the second connecting end 2. Two left and right opposite card slots 510 are opened on the upper side of the connecting block 51. A limiting slot 320 adapted for the connecting block 51 to pass through is opened on the lifting rod 32. When the second connecting end 2 moves to the right, it will drive the connecting block 51 to move to the right through the limiting slot 320 on the lifting rod 32. A clamping rod 52 adapted to be inserted into the card slot 510 is connected to the limiting slot 320 of the lifting rod 32. During the process of the second connecting end 2 moving to the right and being inserted into the first connecting end 1, when the first wedge-shaped block 22 moves to the right and squeezes the limiting plate 34 to move upward, the limiting plate 34 will drive the clamping rod 52 to move upward through the lifting rod 32. Then the second connecting end 2 drives the connecting block 51 to move to the right through the limiting slot 320. When the first wedge-shaped block 22 passes over and releases the limiting plate 34, at this time, the card slot 510 on the connecting block 51 is exactly located directly below the clamping rod 52. The released limiting plate 34 will drive the clamping rod 52 to move downward through the lifting rod 32 under the action of the tension spring 33 and insert it into the card slot 510 on the connecting block 51, so that on the basis that the first wedge-shaped block 22 on the upper side of the second connecting end 2 is restricted in the left-right direction, the connecting block 51 is restricted in the front-rear direction by the clamping rod 52, further increasing the stability during insertion at different positions; during the unlocking process, when the limiting plate 34 moves upward and releases the first wedge-shaped block 22, it will also drive the clamping rod 52 to move upward out of the card slot 510 of the connecting block 51 through the lifting rod 32, thereby automatically and synchronously unlocking the connecting block 51.

[0036] As Figure 6 shown in the figure, it further includes a locking assembly 6. There are contact points 210 for contact and cooperation with the pin group 11 in the jack group 21. When the second connecting end 2 moves to the right and is inserted onto the first connecting end 1, the contact points 210 in the jack group 21 will be in contact and cooperation with the pin group 11 to transmit signals in this way. The side of the contact point 210 away from the pin group 11 is adapted to be in contact and cooperation with the transmission line. The end of the transmission line is connected from the left side of the jack group 21 on the second connecting end 2. A locking assembly 6 is provided on the second connecting end 2. The locking assembly 6 is used to lock the transmission line inserted into the jack group 21 for stable connection in this way, and each different transmission line can be respectively connected and removed on different jack groups 21 without affecting each other.

[0037] As Figures 7-9As shown, the locking component 6 includes a support block 61 rotatably arranged on the upper part of the second connection end 2. The number of support blocks 61 is the same as that of the jack groups 21, and the support blocks 61 correspond to the jack groups 21 one by one. Torsion springs 62 located inside the second connection end 2 are connected between the front and rear sides of the support block 61 and the second connection end 2. The torsion springs 62 are used to reset the rotated support block 61. A dial block 64 and a pressing block 63 adapted to move in the jack group 21 are respectively connected to the upper and lower sides of the support block 61. When the transmission line needs to be inserted into the jack group 21, first, the dial block 64 is pushed upward to drive the pressing block 63 to swing upward clockwise through the support block 61, and the torsion spring 62 deforms. At this time, the pressing block 63 is in a released state where it does not block the jack group 21 (as Figure 9 ), and then the transmission line can be normally inserted into the jack group 21 and contact the contact point 210. Then, the dial block 64 is released, and the torsion spring 62 resets. The support block 61 will drive the pressing block 63 to swing downward counterclockwise under the action of the reset of the torsion spring 62 to press the transmission line inserted into the jack group 21, thereby locking the transmission line and improving the stability when the transmission line is inserted.

[0038] As Figure 8 and Figure 9 shown, it further includes a clamping block 71 connected to the support block 61. A spring piece 72 is connected inside the second connection end 2 and is located to the right of the clamping block 71. A bayonet 73 adapted to clamp the clamping block 71 is formed on the spring piece 72. Initially, the bayonet 73 on the spring piece 72 clamps the clamping block 71, the pressing block 63 is in a released state, and the torsion spring 62 is in a deformed state. A notch 74 is formed above the bayonet 73 on the spring piece 72 and is adapted to allow the clamping block 71 to pass through. The lower end of the spring piece 72 extends into the jack group 21. Thus, during the process of the transmission line being inserted into the jack group 21 to the right and contacting the contact point 210, the transmission line will squeeze the lower end of the spring piece 72 to the right to deform the spring piece 72, and the bayonet 73 on the spring piece 72 will gradually move to the right to release the clamping block 71. The torsion spring 62 resets, and the support block 61 will drive the pressing block 63 to rotate and swing downward counterclockwise under the action of the reset of the torsion spring 62, so as to automatically and synchronously clamp the transmission line into the jack group 21 when the transmission line is inserted into the jack group 21, which is convenient for operation; if the transmission line needs to be removed from the jack group 21, the operator holds the transmission line by hand and rotates the dial block 64 clockwise to move it upward. The dial block 64 will drive the pressing block 63 to swing upward clockwise through the support block 61 to release the transmission line. At this time, a pulling force can be applied to the left with the dial block 64 as the fulcrum to remove the transmission line from the jack group 21, and the disassembly and assembly operations of the transmission line are convenient.

[0039] As Figure 10As shown, there are two upper and lower opposite contact pieces 8 on the contact point 210 in the jack group 21, which are adapted to contact the pin group 11. During the process of inserting the second connection end 2 into the first connection end 1, the pin group 11 will be inserted between the two contact pieces 8. On the side where the two contact pieces 8 are close to each other, there are two left and right opposite convex portions 81 protruding in the direction of approaching each other. The four convex portions 81 on the contact pieces 8 are respectively used to contact different positions of the pin group 11.

They only express the preferred embodiments of the present invention, and the description is relatively specific and detailed, but it cannot be construed as a limitation on the scope of the patent of the present invention.

[0041] It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations, quantity increases or decreases, improvements and substitutions can be made. Therefore, based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.
