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 an accessory product used to achieve electrical connections, and are classified as connectors in the industry. With the increasing degree of industrial automation and the increasingly stringent and precise requirements for industrial control, the use of terminal connectors is gradually increasing.
[0003] The existing terminal connectors have a relatively simple fixing method when docking wires. If the terminal connectors are offset or other external forces touch them during use, there is a risk that the wires at the connection points of the terminal connecting wires 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 touched during use, there is a risk of the wires at the connection of the terminal connecting wire falling 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: A terminal connector comprises 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 arranged inside each wire hole, the wire reinforcement assembly comprises 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 of the wire hole near the top, the top of the lower adjustment pressure plate is fixedly connected to two pulling rods, the top of the upper fixed pressure plate is provided with two through holes, the pulling rod passes through the through holes, connecting spring rods are fixedly connected at equal distances on opposite sides of the upper fixed pressure plate and the lower adjustment pressure plate, and wire grooves are provided at the middle of the upper fixed pressure plate and the lower adjustment pressure plate, the inner side walls of the two wire grooves are fixedly connected with air bag columns at equal distances, the tops of the two pulling rods are fixedly connected to the same integrated lifting rod, and the wire threading frame is provided with a connecting hole at each pulling rod, the pulling rod passes through the connecting hole.
[0006] By providing a wire reinforcement assembly, when the wire is connected to the connector body, the pull rod is pressed manually to press the lower adjustment pressure plate downward. When the wire passes through the 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.
[0007] 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.
[0008] By providing an interface sealing component, 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 to make the compressed gas inside flow 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, thereby reducing the pollution of the dust carried in the air to the wire and protecting the wire.
[0009] 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 hole on both sides of the annular adjustment groove, and an annular sealing airbag is fixedly connected to the opposite side of the two sealing covers.
[0010] 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.
[0011] In a preferred solution, sliding blocks are equidistantly slidably connected inside 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, and a connecting rod is connected between each two adjacent sliding blocks through a hinge, and the bottom end of the pressure rod is connected to the top of the uppermost sliding block through a hinge.
[0012] 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 docking grooves are provided on the connector body at the docking seats, and the docking seats are inserted into the docking grooves.
[0013] By providing a docking assembly, when docking the wire threading frame and the connector body, the docking seat is inserted into the docking groove. During the insertion of the docking seat, the extrusion deflection plate is deflected 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 protruding card rod on the limiting card plate is gradually inserted into 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, so that the docking seat can be slowly pulled out of the docking slot to complete the disassembly operation.
[0014] In a preferred embodiment, the top and bottom of the docking seat are both provided with deflection grooves, 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 with extrusion spring rods 2 at equal distances, one end of the extrusion spring rods 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.
[0015] In a preferred embodiment, the connector body is provided with alignment through holes at the upper and lower ends of the docking groove, and the top inner wall and the bottom inner wall of the docking groove between the docking through holes are evenly fixedly connected with an extrusion spring rod, and one end of multiple extrusion spring rods on the same surface is fixedly connected with the same limiting clamp.
[0016] 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 in 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.
[0017] As can be seen from the above, the terminal connector provided by the present invention has the 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 from 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 a state of vibration due to external force, the air bag column and the connecting spring rod have the technical effect of reducing the impact of vibration on the wire.

The wire located inside the wire groove 607 is squeezed and limited by the air bag column 606 inside the wire groove 607 and the connecting spring rod 605 in a compressed state, thereby improving its stability after connection.
