Description

Technical Field

[0001] The present invention relates to the technical field of terminal connectors, and in particular to a terminal connector. Background Art

[0002] Terminal connectors are accessories used to achieve electrical connections and are classified as connectors in the industrial field. With the increasing degree of industrial automation and increasingly stringent and precise industrial control requirements, the use of terminal connectors has gradually increased.

[0003] The existing terminal connectors have a relatively simple fixing method when docking wires. If the terminal connectors are offset or other external forces occur during use, there is a risk that the wires at the terminal connection points will fall off, resulting in safety hazards during use of the terminal connectors and reducing the use value of the terminal connectors. Summary of the Invention

[0004] The present invention discloses a terminal connector, which aims to solve the technical problem that the existing terminal connector has a relatively single fixing method when docking wires. If the terminal connector is offset or other external forces are encountered during use, there is a risk that the wires at the connection point of the terminal connection line will fall off, resulting in a safety hazard during use of the terminal connector.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] The terminal connector includes a connector body and a wire threading frame, one side of the wire threading frame is provided with wire holes at equal distances, and a wire reinforcement assembly is provided inside each wire hole, the wire reinforcement assembly includes an upper fixed pressure plate and a lower adjustment pressure plate, and the upper fixed pressure plate is fixedly connected to the inner side wall near the top of the wire hole, the top of the lower adjustment pressure plate is fixedly connected to two pull rods, the top of the upper fixed pressure plate is provided with two through holes, the pull rod passes through the through holes, the opposite sides of the upper fixed pressure plate and the lower adjustment pressure plate are fixedly connected with connecting spring rods at equal distances, and the upper fixed pressure plate and the lower adjustment pressure plate are both provided with wire grooves in the middle, the inner side walls of the two wire grooves are fixedly connected with air bag columns at equal distances, the tops of the two pull rods are fixedly connected with the same integrated lifting rod, and the wire threading frame is provided with a connecting hole at each pull rod, and the pull rod passes through the connecting hole.

[0007] By providing a wire reinforcement assembly, when the wire is connected to the connector body, the pull rod is manually pressed to press the lower adjustment pressure plate downward. When the wire passes through the wire threading frame to the inside of the connector body, the pressure of the pull rod is released, and the connecting spring rod drives the lower adjustment pressure plate to move toward the upper fixed pressure plate. The wire inside the wire groove is squeezed and limited by the air bag column inside the wire groove and the connecting spring rod in a compressed state, thereby improving its stability after connection. At the same time, if the terminal connector is in an oscillating state due to external force, the air bag column and the connecting spring rod reduce the impact of the vibration on the wire, thereby improving the use value of the terminal connector.

[0008] In a preferred solution, the threading frame is provided with an interface sealing assembly at an equal distance away from the connector body, and the interface sealing assembly includes two sealing covers and an annular sealing airbag.

[0009] By providing an interface sealing assembly, after the wire passes through the wire threading frame, the pressure rod is manually pressed to press each sliding block into the annular adjustment groove, and the outer side of the annular sealing airbag is squeezed by the squeezing ball, so that the compressed gas inside it flows toward the wire, thereby making the annular sealing airbag fit tightly with the outer side wall of the wire. In this state, the annular sealing airbag cooperates with the two sealing covers to achieve sealing at the wire hole of the wire threading frame, reducing the pollution of the dust carried in the air to the wire and protecting the wire.

[0010] In a preferred embodiment, the wire threading frame has an annular adjustment groove inside each wire hole, and two sealing covers are fixedly connected to the inside of the wire holes on both sides of the annular adjustment groove, and the annular sealing airbags are fixedly connected to the opposite sides of the two sealing covers.

[0011] In a preferred solution, the threading frame is provided with two docking holes above each annular adjustment groove, and a pressure rod is inserted into each docking hole.

[0012] In a preferred solution, sliding blocks are equidistantly connected to the inside of the annular adjustment groove, and a squeezing ball is fixedly connected to the side of each sliding block facing the annular sealing airbag. The squeezing ball and the annular sealing airbag are in a squeezing state. A connecting rod is connected between each adjacent sliding block through a hinge, and the bottom end of the pressure rod is connected to the top of the uppermost sliding block through a hinge.

[0013] In a preferred solution, a docking assembly is provided on the side of the threading frame facing the connector body, and the docking assembly includes two docking seats, and the connector body is provided with docking grooves at the docking seats, and the docking seats are inserted into the docking grooves.

[0014] By providing a docking assembly, when docking the wire threading frame and the connector body, the docking seat is inserted into the docking slot. During the insertion of the docking seat, the extrusion deflection plate deflects toward the docking seat, and the extrusion spring rod 2 is in a compressed state, thereby realizing the initial docking and fixation between the docking seat and the connector body. As the docking seat is continuously inserted, the docking seat squeezes the limiting card plate, so that the extrusion spring rod 1 is gradually compressed, and the raised card rod on the limiting card plate is gradually stuck in the adapter card slot on the docking seat, completing the secondary docking and fixation between the docking seat and the connector body, thereby improving the firmness of the docking between the wire threading frame and the connector body. At the same time, if it is necessary to disassemble the connector body and the wire threading frame, the lifting plate is manually pulled to pull the card rod on the limiting card plate out of the adapter card slot in the docking seat, and then the docking seat can be slowly pulled out of the docking slot to complete the disassembly operation.

[0015] In a preferred embodiment, deflection grooves are provided at the top and bottom of the docking seat, and the interiors of the two deflection grooves are connected to deflection shafts through bearings. The outer walls of the two deflection shafts are sleeved with extrusion deflection plates, and the side of the extrusion deflection plate facing the docking seat is fixedly connected to an extrusion spring rod 2 at an equal distance, one end of the extrusion spring rod 2 is fixedly connected to the outer wall of the docking seat, and the extrusion deflection plate is in contact with the interior of the docking groove.

[0016] In a preferred embodiment, the connector body is provided with alignment holes at the upper and lower ends of the docking slot, and the top inner wall and the bottom inner wall of the docking slot between the docking holes are fixedly connected with an extrusion spring rod 1 at equal distances, and one end of multiple extrusion spring rods 1 located on the same surface is fixedly connected with the same limiting clamping plate.

[0017] In a preferred solution, a clamping rod is fixedly connected to the arc surface of the limit clamping plate facing the docking seat, and an adapter slot is opened on the outer wall of the docking seat at the clamping rod, the clamping rod fits into the adapter slot, and the facing sides of the two limit clamping plates are fixedly connected to fixing rods, and the facing ends of the two fixing rods are fixedly connected to lifting plates.

[0018] From the above, it can be seen that the terminal connector provided by the present invention has a function of manually pressing the pull rod to press the lower adjustment pressure plate downward when docking the wire with the connector body. When the wire passes through the wire threading frame to the inside of the connector body, the pressure of the pull rod is released, and the connecting spring rod drives the lower adjustment pressure plate to move toward the upper fixed pressure plate. The wire located inside the wire groove is squeezed and limited by the air bag column inside the wire groove and the connecting spring rod in a compressed state, thereby improving its stability after connection. At the same time, if the terminal connector is in an oscillating state due to external force, the air bag column and the connecting spring rod reduce the technical effect of reducing the impact of vibration on the wire.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] The terminal connector disclosed in the present invention is mainly used for connecting wires with existing terminal connectors. The fixing method is relatively simple. If the terminal connector is offset or touched by other external forces during use, there is a risk that the wires at the connection point of the terminal connection line will fall off, resulting in a safety hazard when using the terminal connector.

[0029] Reference Figures 1-7The terminal connector includes a connector body 1 and a wire threading frame 4. A wire hole is opened at equal distances on one side of the wire threading frame 4, and a wire reinforcement component 6 is provided inside each wire hole. The wire reinforcement component 6 includes an upper fixed pressure plate 602 and a lower adjustment pressure plate 604. The upper fixed pressure plate 602 is fixedly connected to the inner side wall near the top of the wire hole. The top of the lower adjustment pressure plate 604 is fixedly connected to two pull rods 603. The top of the upper fixed pressure plate 602 has two through-holes, and the pull rod 603 passes through the through-holes. The upper fixed pressure plate 602 and the lower adjusting pressure plate 604 are fixedly connected to the opposite side with connecting spring rods 605 at equal distances, and the upper fixed pressure plate 602 and the lower adjusting pressure plate 604 are both provided with wire grooves 607 in the middle, and the inner side walls of the two wire grooves 607 are fixedly connected with airbag columns 606 at equal distances, and the tops of the two pulling rods 603 are fixedly connected with the same integrated lifting rod 601, and the threading frame 4 is provided with a connecting hole 7 at each pulling rod 603, and the pulling rod 603 passes through the connecting hole 7.

[0030] In a specific application scenario, when docking the wire with the connector body 1, the pull rod 603 is manually pressed to press the lower adjustment pressure plate 604 downward. When the wire passes through the wire threading frame 4 to the inside of the connector body 1, the pressure of the pull rod 603 is released, and the connecting spring rod 605 drives the lower adjustment pressure plate 604 to move toward the upper fixed pressure plate 602. The air bag column 606 inside the wire groove 607 and the connecting spring rod 605 in a compressed state squeeze and limit the wire inside the wire groove 607, thereby improving its stability after connection. At the same time, if the terminal connector is in an oscillating state due to external force, the air bag column 606 and the connecting spring rod 605 reduce the impact of vibration on the wire, thereby improving the use value of the terminal connector.

[0031] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 5In a preferred embodiment, the threading frame 4 is provided with an interface sealing assembly 3 at an equal distance away from the connector body 1, and the interface sealing assembly 3 includes two sealing covers 303 and an annular sealing airbag 301.

The threading frame 4 is provided with two docking holes above each annular adjustment groove 8, and a pressure rod 302 is inserted into the inside of each docking hole. Sliding blocks 304 are slidably connected to the inside of the annular adjustment groove 8 at equal distances, and each sliding block 304 is fixedly connected to a squeezing ball 305 on the side facing the annular sealing airbag 301. The squeezing ball 305 and the annular sealing airbag 301 are in a squeeze state. Each adjacent two sliding blocks 304 are connected by a connecting rod 306 through a hinge, and the bottom end of the pressure rod 302 is connected to the top of the uppermost sliding block 304 through a hinge.

[0032] Specifically, after the wire passes through the wire threading frame 4, the pressure rod 302 is manually pressed to press each sliding block 304 into the annular adjustment groove 8, and the outer side of the annular sealing airbag 301 is squeezed by the squeezing ball 305, so that the compressed gas inside it flows toward the wire, thereby making the annular sealing airbag 301 fit tightly with the outer wall of the wire. In this state, the annular sealing airbag 301 cooperates with the two sealing covers 303 to achieve sealing at the wire hole of the wire threading frame 4, reducing the pollution of the dust carried in the air to the wire and protecting the wire.

[0033] Reference Figure 1 、 Figure 2 、 Figure 6 and Figure 7In a preferred embodiment, a docking assembly 5 is provided on the side of the threading frame 4 facing the connector body 1, and the docking assembly 5 includes two docking seats 501, and the connector body 1 is provided with docking grooves at the docking seats 501, and the docking seats 501 are inserted into the interior of the docking grooves, and deflection grooves 506 are provided on the top and bottom of the docking seat 501, and the interiors of the two deflection grooves 506 are connected to deflection shafts 510 through bearings, and the outer walls of the two deflection shafts 510 are sleeved with extrusion deflection plates 505, and the extrusion deflection plates 505 are fixedly connected to the side of the extrusion deflection plates 505 facing the docking seat 501 at equal distances. One end of the extrusion spring rod 509 is fixedly connected to the outer wall of the docking seat 501, and the extrusion deflection plate 505 contacts the interior of the docking groove, and the connector body 1 is located in the docking groove. There are alignment through-holes 2 at the upper and lower ends, and the docking grooves are located at the top inner wall and the bottom inner wall between the docking through-holes, and are fixedly connected with extrusion spring rods 502 at equal distances. One end of multiple extrusion spring rods 502 located on the same surface is fixedly connected with the same limiting clamping plate 504, and the limiting clamping plate 504 is fixedly connected with a clamping rod 508 on the arc surface facing the docking seat 501, and the outer wall of the docking seat 501 located at the clamping rod 508 is provided with an adaptation slot, and the clamping rod 508 fits with the adaptation slot, and the opposite sides of the two limiting clamping plates 504 are fixedly connected with fixing rods 507, and the opposite ends of the two fixing rods 507 are fixedly connected with lifting plates 503, and the fixing rods 507 and the lifting plates 503 are both located in the alignment through-holes 2, and the alignment through-holes 2 are through-holes with a small diameter at the lower end and a large diameter at the upper end.

[0034] It should be noted that when the threading frame 4 and the connector body 1 are docked, the docking seat 501 is inserted into the docking groove.

At the same time, if it is necessary to separate the connector body 1 and the threading frame 4, manually pull the lifting plate 503 to pull the card rod 508 on the limit card plate 504 out of the adapter card slot in the docking seat 501, and then the docking seat 501 can be slowly pulled out of the docking slot to complete the separation operation.
