[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In order to solve the technical problem that the traditional wires are fixed with screws when they are connected or removed, frequent removal will cause the screws to slip and be difficult to disassemble, such as Figure 1 - Figure 2 and Figure 5As shown, the following preferred technical solutions are provided: a connector terminal structure, including a connector housing 1 and a wiring hole 2 opened on the side of the connector housing 1, an upper movable module 3, a lower movable module 4, a stripping module 5, a cleaning module 6, an upper clamping assembly 7, a lower clamping assembly 8, a pneumatic clamping assembly 9 and a sealing assembly 10 are respectively installed in the connector housing 1, the upper movable module 3 includes a connecting shell 31 slidably mounted on the upper end of the connector housing 1, the upper clamping assembly 7 includes a connecting block 71 fixedly mounted on the lower end of the connecting shell 31, and a card block 72 is fixedly installed equidistantly inside the connecting block 71, and the lower movable module 4 includes a sliding mounting At the connecting shell 2 41 at the lower end of the connector housing 1, the lower clamping assembly 8 includes movable connecting blocks 82 fixedly installed on both sides of the connecting shell 2 41, a fixed block 81 is installed between the two movable connecting blocks 82, and the sides of the two movable connecting blocks 82 are fixedly installed with clamping blocks 2 83 at equal intervals, and the clamping blocks 1 72 and the clamping blocks 2 83 are staggered. The four corners of the lower end of the connecting shell 1 31 are fixedly installed with connecting rods 1 34, and the connecting rods 1 34 are evenly spaced. Slots 35 are evenly spaced, and the four corners of the upper end of the connecting shell 2 41 are fixedly installed with connecting rods 2 45, and the side walls of the connecting rods 2 45 are evenly spaced. The clamping teeth 46 can be clamped in the slots 35.

[0031] The wire stripping module 5 includes a fixed ring 51 fixedly installed on the inner wall of the connector housing 1, and the upper and lower walls of the fixed ring 51 are provided with sliding grooves 52, and a movable ring 53 is slidably connected in the sliding groove 52. A fixed blade 54 is slidably connected to the inner wall of the upper end of the fixed ring 51, and the fixed blade 54 is fixedly connected to the movable ring 53. A movable blade 55 is slidably connected to the inner wall of the lower end of the fixed ring 51, and the wire inserted into the fixed ring 51 can be stripped by the fixed blade 54 and the movable blade 55.

[0032] Specifically, when connecting the wire, one end of the wire can be directly inserted into the connector housing 1 through the wiring hole 2. At this time, the upper and lower connecting shells 31 and the second connecting shell 41 can be pushed into the interior of the connector housing 1 at the same time. When the connecting shell 31 is pushed into the connector housing 1, the connecting block 71 at the lower end can be driven to approach the wire. When the connecting block 71 moves, the clamping block 72 can be driven to move toward the lower end. When the connecting shell 31 is pushed downward, the connecting rod 34 can be driven to move toward the middle of the connector housing 1 at the same time. Similarly, when the connecting shell 41 is lifted upward, the clamping block 83 can be driven to approach the wire in the middle. The connecting rod 45 will contact the connecting rod 34 when moving. The clamping groove 35 and the clamping tooth 46 can complete the fixation of the clamping block 72 and the second clamping block 83. Under the action of the staggered clamping block 72 and the second clamping block 83, the wire can be squeezed into a multi-section bending state in the connector housing 1, which can make the fixation of the wire more firm and stable.

[0033] When the wire needs to be removed and replaced, the two sides of the connecting shell 41 can be pushed toward the middle. The connecting shell 41 is squeezed toward the middle to drive the connecting rods 45 on both sides to move toward the middle at the same time. After moving a certain distance, the latch teeth 46 slide out of the latch groove 35. At this time, the latch block 72 and the latch block 83 are limited by the latch teeth 46 and the latch groove 35. The connecting shells 31 and 41 at the upper and lower ends can be put into an active state again, and the wire can be pulled out of the wiring hole 2.

[0034] In order to solve the technical problem that the outer skin of the wire needs to be stripped during wiring, the inner core of the wire is easy to spread out during connection, resulting in poor contact, such as Figure 3 - Figure 5 As shown, the following preferred technical solutions are provided: an installation chamber 32 is provided inside the connecting shell 1 31, and corrugated plates 33 are fixedly installed on both side walls of the connecting shell 1 31; an installation chamber 42 is provided inside the connecting shell 2 41, and corrugated plates 43 are fixedly installed on both side walls of the connecting shell 2 41; connecting plates 1 48 are fixedly installed on both inner walls of the connecting shell 2 41; a connecting plate 2 47 is installed between the two connecting plates 1 48, and the connecting plate 1 48 is slidably connected to the connecting plate 2 47; the arrangement of the corrugated plates 1 33 and 2 43 enables the connecting shells 1 31 and 2 41 to be in a connected state with the connector housing 1.

[0035] A spring 1 36 is fixedly installed between the lower wall of the connecting shell 1 31 and the upper wall of the connector housing 1, a spring 2 44 is fixedly installed between the side wall of the connecting plate 1 48 and the inner wall of the connecting shell 2 41, and a spring 3 84 is fixedly installed between the inner walls of the fixed block 81 and the movable connecting block 82. The arrangement of the spring 1 36 and the spring 2 44 can make it possible to push the upper and lower ends of the connecting shell 1 31 and the connecting shell 2 41 outward when there is no engaging relationship between the latch teeth 46 and the latch groove 35, and the spring 3 84 can push the movable connecting block 82 outward after being moved.

[0036] A push rod 57 is fixedly installed at the lower end of the movable blade 55, and one end of the push rod 57 is fixedly connected to the connecting shell 2 41. A spring 4 56 is fixedly installed between the side wall of the movable ring 53 and the inner wall of the connector shell 1. When the connecting shell 2 41 moves, it will drive the movable blade 55 to move in the fixed ring 51. The spring 4 56 can pull the movable ring 53 back to its original position after it moves.

[0037] Specifically, when the wire needs to be removed, the latch teeth 46 can be moved out of the latch slot 35 by squeezing the connecting shell 2 41 toward the middle. At this time, the limit between the connecting shell 1 31 and the connecting shell 2 41 at the upper and lower ends can be released. Under the action of the spring 1 36 and the spring 2 44, the connecting shell 1 31 and the connecting shell 2 41 after the limit is released will be automatically pushed outward to the initial position, so that the clamping and fixation of the wire are released.

[0038] When the wire is fixed and clamped, the outer skin of the wire may not be stripped. After the wire is inserted into the fixed ring 51, one end of the connecting shell 2 41 is moved closer to the outside. At this time, the connecting shell 2 41 drives the push rod 57 to move, and the push rod 57 drives the movable ring 53, the fixed blade 54, and the movable blade 55 to slide in the fixed ring 51. At this time, the connecting shell 2 41 can be pushed into the connector shell 1. When the connecting shell 2 41 is pushed, the push rod 57 will be pushed upward and drive the movable blade 55 to move upward. At this time, the movable blade 55 approaches the fixed blade 54 and cuts the outer skin of the wire between the two. After cutting, the connecting shell 2 41 can be loosened. Under the action of the spring four 56, the movable ring 53 and other parts connected to the movable ring 53 can be pulled toward the connector shell 1 at the same time. During the movement of the spring four 56, the outer skin of the wire is automatically stripped off. At this time, the inner core of the wire can be exposed to the outside, and the stripped wire skin can also tighten the inner core of the wire head end during the movement, so that the inner core of the wire is in a gathered state, which is convenient for connecting the wire.

[0039] In order to solve the technical problem that dust inside the device may cause poor contact when the wires are connected, such as Figure 6 - Fig. 9 As shown, the following preferred technical solution is provided: the cleaning module 6 includes a cavity 61 opened inside the connector housing 1, a connecting rod 3 62 is fixedly installed on the side wall of the connecting shell 1 31, a piston 63 is fixedly installed at one end of the connecting rod 3 62, the piston 63 is slidably connected in the cavity 61, and when the piston 63 moves, the gas in the cavity 61 is pushed and compressed.

[0040] A connecting tube 1 64 is fixedly installed at the lower end of the cavity 61, a telescopic tube 65 is fixedly installed at one end of the connecting tube 1 64, a connecting tube 2 66 is fixedly installed at one end of the telescopic tube 65, the side wall of the connecting tube 2 66 is fixedly connected to the side wall of the movable ring 53, and the air outlet of the connecting tube 2 66 extends into the interior of the fixed ring 51. The compressed gas in the cavity 61 will enter the fixed ring 51 along the connecting tube 1 64, the telescopic tube 65, and the connecting tube 2 66 and be blown out to clean the surface of the wire.

[0041] The pneumatic clamping assembly 9 includes an air chamber 91 opened on both sides of the connector housing 1, a slider 92 is slidably connected in the air chamber 91, a ventilation groove 94 is opened on the inner wall of the fixed ring 51, a connecting groove 93 is opened in the connector housing 1, the connecting groove 93 connects the air chamber 91 and the ventilation groove 94, and pneumatic telescopic rods 95 are fixedly installed on both side walls of the fixed ring 51. The pneumatic telescopic rods 95 are connected to the ventilation grooves 94, and a clamping block 96 is fixedly installed on the movable end of the pneumatic telescopic rod 95. The movement of the slider 92 can push out the gas in the air chamber 91, so that the gas extends the pneumatic telescopic rod 95, driving the clamping block 96 to clamp the wire.

[0042] Two connecting blocks 58 are fixedly installed on both side walls of the movable ring 53. The two connecting blocks 58 are respectively fixedly connected to the side walls of the slider 92 on the same side. When the movable ring 53 moves, it can drive the slider 92 to move.

[0043] The upper and lower walls of the connector housing 1 are provided with mounting grooves 11, and the sealing assembly 10 includes an airbag 101 fixedly installed in the mounting groove 11, a spring five 102 is installed at a common higher point between the upper and lower walls of the airbag 101, and the side walls of the connecting shell 1 31 and the connecting shell 2 41 are fixedly installed with extrusion plates 37, and the extrusion plates 37 are slidably connected in the mounting groove 11, and a connecting tube three 103 is fixedly installed at the lower end of the airbag 101, and an inflation ring 104 is fixedly installed at one end of the connecting tube three 103, and the inflation ring 104 is installed on the inner wall of the wiring hole 2. When the connecting shell 1 31 and the connecting shell 2 41 are pushed into the connector housing 1 to fix the wire, the gas in the airbag 101 can be automatically pushed outward into the inflation ring 104 to expand it, thereby clamping the wire in the wiring hole 2.

[0044] Specifically, when the connecting shell 1 31 is pushed into the connector housing 1, the connecting shell 1 31 moves the connecting rod 3 62 and the piston 63 to slide into the cavity 61. When the piston 63 moves, it pushes the gas in the cavity 61. The gas enters the fixed tube 51 along the connecting tube 1 64, the telescopic tube 65, and the connecting tube 2 66. The gas flows out from the connecting tube 2 66 to clean the outside of the wire and blow away the debris on its surface.

[0045] When stripping the wire, the movement of the movable ring 53 will drive the connecting block 2 58 to move together. The outward movement of the movable ring 53 will cause the slider 92 to slide outward, so that the air chamber 91 is filled with gas. At this time, the pneumatic telescopic rod 95 is retracted, and when the movable ring 53 drives the connecting block 2 58 and the slider 92 to advance into the air chamber 91, the gas in the air chamber 91 will be pushed out by the slider 92, and the gas enters the pneumatic telescopic rod 95 along the connecting groove 93 and the ventilation groove 94. At this time, the clamping block 96 can be pushed outward, and the clamping blocks 96 on both sides clamp and fix the wire in the middle.

[0046] When the connecting shell 1 31 and the connecting shell 2 41 are pushed into the connector housing 1 to clamp and fix the wire, the connecting shell 1 31 and the connecting shell 2 41 will drive the extrusion plate 37 to slide along the mounting groove 11 to squeeze the airbag 101 on the same side. The airbag 101 is squeezed and the gas inside it enters the inflation ring 104 along the connecting tube 3 103. At this time, the inflation ring 104 expands and covers the outer side of the wire in the wiring hole 2 to prevent dust and debris from entering.
