[0005] When assembling existing equipment, the terminals on the left and right sides are mostly designed as separate units, which is time-consuming and labor-intensive. At the same time, when the terminals are docked into the socket, the staff can only rely on their hand feeling to feel whether the terminals are properly docked, and cannot accurately identify whether the terminal assembly is completed.

[0006] Therefore, we propose an anti-misalignment quick-install pin board-to-board connector to solve the above problems. Summary of the invention

[0007] The purpose of the present invention is to provide an anti-misalignment quick-install pin board-to-board connector to solve the problem that the separate single-design terminals currently on the market mentioned in the above background technology are time-consuming and labor-intensive when plugging and assembling. At the same time, when the terminal pair is connected to the inside of the socket, the staff can only rely on the feel of the hand to feel whether the terminals are properly connected, and cannot accurately identify whether the terminal assembly is completed.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a dislocation-proof quick-install pin-board-to-board connector, comprising an upper socket, a lower socket is docked below the upper socket, and terminal docking grooves are provided on the inner sides of the upper socket and the lower socket, and a terminal body is assembled inside the terminal docking groove, a connecting belt is provided on the outer side of the terminal body, and two groups of terminal bodies can be assembled at the same time through the connecting belt, a deformation plate is provided inside the lower socket, and an interference mechanism for detecting the docking condition of the terminal body is provided between the outer side of the deformation plate and the lower socket.

[0009] Preferably, a docking portion protruding outward is provided below the connecting strip, and an outer end side of the docking portion corresponds to an outer side position of the terminal body, and four groups of docking portions are arranged at equal intervals below the connecting strip.

[0010] Preferably, a docking groove body is opened on both end sides of the upper socket, and a connecting ring is fixedly connected inside the docking groove body, and an elastic pressing plate is fixedly connected above the connecting ring, and a docking block is fixedly connected above the side of the lower socket, and the docking block is nested and connected inside the docking groove body.

[0011] Preferably, the elastic pressing piece is arranged in a zigzag elastic structure, and the zigzag protruding portion of the elastic pressing piece contacts the side of the docking block, and the docking slot body is arranged in two groups symmetrically about the center point of the upper socket.

[0012] Preferably, a rotation groove is opened on the upper end side of the upper socket, and a fixed shaft is fixedly connected inside the rotation groove, and a resistance wheel is nested and connected outside the fixed shaft, and a resistance fixed block is fixedly connected outside the resistance wheel.

[0013] Preferably, the inner side of the rotating groove and the terminal docking groove are interconnected, the inner side of the contact wheel and the side of the terminal body are in contact with each other, and the contact wheel is supported by an insulating material, and the contact fixing block is arranged in an upward zigzag structure, and the contact wheel forms a rotating structure through the terminal body and the fixed axis, and the position of the contact fixing block corresponds to that of the terminal body.

[0014] Preferably, the resistance mechanism includes a detection groove, a deformation plate is fixedly connected to the inside of the detection groove, and an auxiliary resistance block is fixedly connected to the side of the deformation plate, and a card slot is opened below the deformation plate, a detection block is dockedly arranged inside the detection groove, and an insertion slot is opened on the upper side of the detection block.

[0015] Preferably, the detection grooves are arranged at equal distances with respect to the lower socket, and the detection grooves correspond to the terminal docking grooves in one-to-one position, and the lower end of the deformation plate can be bent under the interference of the terminal body.

[0016] Preferably, under normal circumstances, the deformable plate and the detection block can be connected to each other through the docking action of the insertion slot and the card slot, and the bent deformable plate cannot be docked with the detection block, and the length of the insertion slot is greater than the length of the card slot.

[0017] Compared with the prior art, the beneficial effects of the present invention are that the efficiency of stamping production can be improved through the connecting belt, the production capacity of parts can be increased, the docking block can be clamped through the elastic force of the elastic pressing sheet itself, and the stability of the docking between the upper socket and the lower socket can be further improved. The placement of the terminal body inside the lower socket can be detected through the interference mechanism, and the stability of the terminal body docking can be simultaneously improved when the terminal body is docked on the upper socket through the interference fixing block.

[0018] Four groups of docking parts are arranged on the lower side of the connecting belt, and four groups of terminal bodies can be plugged in at the same time through the connecting belt, thereby reducing the working efficiency of the terminal body plugging. While utilizing the distance between the two groups of sockets, it can save materials, further improve the efficiency of stamping production, and increase the production capacity of parts.

[0019] When the upper socket and the lower socket are docked, the docking block arranged on the upper surface of the lower socket can be docked to the inside of the docking groove body opened on the lower surface of the upper socket, thereby completing the assembly and docking of the two sets of sockets.

[0020] The docking block passes through the connecting ring inside the docking slot body for docking. At the same time, the side of the docking block will resist the elastic pressure sheet, causing the elastic pressure sheet to undergo elastic deformation. At the same time, the elastic pressure sheet will exert a reaction force on the docking block under the drive of its own elastic force, thereby clamping the docking block. The elastic pressure sheet can further improve the docking stability between the upper socket and the lower socket.

[0021] When the terminal body on the upper socket is plugged in through the connecting belt, the terminal body slides and docks along the inside of the terminal docking groove. When the terminal body is about to be docked, the side of the terminal body will come into contact with the side of the interference wheel, and the interference wheel is driven to rotate along the fixed axis through the downward force of the terminal body itself and the friction force. At this time, the interference wheel can synchronously drive the upwardly bent interference fixing block to rotate, so that the arc-shaped bending part of the interference fixing block conflicts with the side of the terminal body, and the terminal body is pressed and contacted by the interference fixing block, thereby further improving the stability of the terminal body docking and reducing the occurrence of looseness of the terminal body after docking.

[0022] When the terminal body inside the lower socket is connected, the detection block can be placed in the detection groove, so that the detection block can be connected and assembled with the deformation plate through the connection between the insertion groove opened on the inner side and the clamping groove opened on the lower side of the deformation plate. When the deformation plate and the detection block can be assembled, the terminal body inside the lower socket is in an accurate assembly state. When the assembly position of the terminal body inside the lower socket is inaccurate, the terminal body will contact the side of the deformation plate, so that the lower end of the deformation plate will bend toward the side of the clamping groove. At this time, when the detection block is placed, the clamping groove is blocked by the lower end of the deformation plate, and the detection block cannot be connected with the deformation plate, so that the placement of the detection block is blocked, thereby reminding the assembler that the corresponding terminal body docking position is not assembled correctly, so the position of the terminal body is reassembled.

The end side corresponds to the outer position of the terminal body 2, and the docking portion 20 is arranged in four groups at equal intervals below the connecting belt 8. A docking groove body 4 is opened on the two end sides of the upper socket 1, and a connecting ring 6 is fixedly connected to the inside of the docking groove body 4, and an elastic pressing piece 7 is fixedly connected to the top of the connecting ring 6. A docking block 5 is fixedly connected to the top of the side of the lower socket 3, and the docking block 5 is nested and connected to the inside of the docking groove body 4. The elastic pressing piece 7 is arranged in a tortuous elastic structure, and the tortuous protruding part of the elastic pressing piece 7 is in contact with the side of the docking block 5. Two groups of docking groove bodies 4 are symmetrically arranged about the center point of the upper socket 1.

[0027] Four groups of docking parts 20 are arranged on the lower side of the connecting belt 8. Through the connecting belt 8, four groups of terminal bodies 2 can be plugged in at the same time, thereby reducing the working efficiency of the plug-in of the terminal body 2. While utilizing the distance between the two groups of sockets, it can save materials and further improve the efficiency of stamping production and the production capacity of parts. When the upper socket 1 and the lower socket 3 are docked, the docking block 5 arranged on the upper surface of the lower socket 3 can be docked to the inside of the docking groove body 4 opened on the lower surface of the upper socket 1, thereby completing the assembly and docking of the two groups of sockets. The docking block 5 passes through the connecting ring 6 inside the docking groove body 4 for docking. At the same time, the side of the docking block 5 will resist the elastic pressing sheet 7, causing the elastic pressing sheet 7 to undergo elastic deformation. At the same time, the elastic pressing sheet 7, driven by its own elastic force, will exert a reaction force on the docking block 5, thereby clamping the docking block 5. The elastic pressing sheet 7 can further improve the stability of the docking between the upper socket 1 and the lower socket 3.

A card slot 14 is provided at the bottom, a detection block 15 is docked inside the detection slot 16, and an insertion slot 18 is provided on the upper side of the detection block 15. The detection slots 16 are arranged at equal distances with respect to the lower socket 3, and the detection slots 16 correspond to the terminal docking slots 19 in one-to-one position. The lower end of the deformation plate 13 can be bent under the interference of the terminal body 2. Under normal circumstances, the deformation plate 13 and the detection block 15 can be connected to each other through the docking action of the insertion slot 18 and the card slot 14, and the bent deformation plate 13 cannot be docked with the detection block 15, and the length of the insertion slot 18 is greater than the length of the card slot 14.

When the deformation plate 13 and the detection block 15 can be assembled, the terminal body 2 inside the lower socket 3 is in an accurate assembly state. When the assembly position of the terminal body 2 inside the lower socket 3 is inaccurate, the terminal body 2 will resist the side of the deformation plate 13, so that the lower end of the deformation plate 13 is bent toward the card slot 14. At this time, when the detection block 15 is placed, the card slot 14 is blocked by the lower end of the deformation plate 13, and the detection block 15 cannot be docked with the deformation plate 13, so that the insertion of the detection block 15 is blocked, thereby reminding the assembler that the corresponding terminal body 2 docking position is assembled incorrectly, so the position of the terminal body 2 is reassembled.

At this time, the interference wheel 11 can synchronously drive the upwardly bent interference fixing block 9 to rotate, so that the arc-shaped bending part of the interference fixing block 9 conflicts with the side of the terminal body 2. The terminal body 2 is pressed and contacted by the interference fixing block 9, thereby further improving the stability of the terminal body 2 docking and reducing the occurrence of looseness of the terminal body 2 after docking.
