Description

Technical Field

[0001] The invention relates to the technical field of connectors, in particular to a self-locking connector plug-in structure that prevents misalignment. Background Art

[0002] Connectors are mainly used in electrical connections. They are electronic components used to connect power sources to electronic devices. They are usually composed of plugs and sockets to facilitate the connection and disconnection of power. Power connectors are widely used in various electronic devices. The metal contacts inside the connector may tilt due to misalignment during the contact process, resulting in subsequent misalignment of the connection, affecting the effect of the electrical connection.

[0003] The utility model with publication number CN214379104U discloses a self-locking plug and socket connector that prevents mis-insertion. When the plug and socket are connected, the two bosses on the plug base will squeeze into the two grooves on the socket base to achieve self-locking. The chamfered end of the plug base can be smoothly inserted along the chamfer of the inner cavity of the socket base to achieve the anti-mis-insertion function. Otherwise, the plug and socket cannot be connected.

[0004] The utility model with publication number CN216624729U discloses an anti-misalignment quick connector, which realizes an anti-misalignment function for the connector through the arrangement of a main body, a connector head, an anti-misalignment mechanism, a bearing, a threaded sleeve, a sleeve, a threaded groove, a fixing mechanism, a mounting plate, a hinge, a fixing sheet and a fixing hole, thereby solving the problem that the connector is easily misaligned during work, which leads to poor use effect of the connector, affecting the connection efficiency and reducing the applicability, thereby providing effective protection for the anti-misalignment of the connector.

[0005] However, the above-mentioned connector with anti-misalignment function still has the following problems during actual use: although the anti-misalignment effect of the connector during plugging is improved by chamfering and beveling, the connectors that are plugged into each other do not have a mutual locking mechanism during use, and thus the stability of the connection cannot be guaranteed during the plugging process. At the same time, it is also impossible to avoid the accuracy of the docking between the internal contact pins and the contact pieces during the plugging process, which reduces the fatigue resistance of the metal contact pins, and ultimately leads to unstable contact due to insufficient normal force.

[0006] Therefore, we propose a self-locking connector plug-in structure that prevents misalignment, so as to solve the above-mentioned problems. Summary of the invention

[0007] The purpose of the present invention is to provide a self-locking connector plug-in structure that prevents misalignment, in order to solve the problem that the existing anti-misalignment effect of the connector during plug-in is improved by chamfering and bevels, but the connectors that are plugged into each other do not have a mutual locking mechanism during use, and thus the stability of the connection cannot be guaranteed during the plug-in process. At the same time, it is also impossible to avoid the accuracy of the docking between the internal contact pins and the contact pieces during the plug-in process, which reduces the fatigue resistance of the metal contact pins and causes the contact to be unstable due to insufficient normal force.

[0008] To achieve the above-mentioned object, the present invention provides the following technical solutions: a self-locking connector plug-in structure with anti-dislocation, comprising a connector body, and a plug-in cavity opened inside the connector body, wherein metal contact pins are fixedly arranged at equal distances on the upper and lower sides of the plug-in cavity;

[0009] A docking device body is disposed behind the connector body, and a metal contact piece is fixedly disposed inside the docking device body; and further comprising:

[0010] The bottom surface of the docking device body is provided with a guide mechanism, and the guide mechanism includes a guide bottom plate, and the rear end of the guide bottom plate is fixedly mounted on the bottom surface of the docking device body;

[0011] Wherein, locking mechanisms are arranged on both sides of the docking device body, and the locking mechanisms include locking bars, and the bottom ends of the locking bars are rotatably arranged on the left and right sides of the exterior of the docking device body through torsion springs.

[0012] Preferably, the guide mechanism includes a guide column, and the top end of the guide column is fixedly arranged on the left and right sides of the bottom surface of the connector body, and the guide mechanism includes a resistance arc hook, and the resistance arc hook is fixedly arranged on the left and right sides of the front end of the guide base plate.

[0013] Preferably, the guide base plate included in the guide mechanism follows the docking body and the connector body for insertion, and the outer end of the guide base plate slides in contact with the inner walls of the guide columns on the left and right sides of the bottom surface of the connector body, and is limited to the outer wall of the guide column by the abutment arc hook at the outer end of the guide base plate.

[0014] Preferably, the locking mechanism includes a locking plug plate, and locking sliders are elastically slid on the upper and lower sides of the inner front end of the locking plug plate, and the outer ends of the locking sliders on the left and right sides slide through the outside of the front end of the locking plug plate, and the symmetrically arranged locking sliders and the bottom end of the locking bar are connected to each other through a traction steel cable.

[0015] Preferably, the locking mechanism includes a locking frame, and the interior of the locking frame is slidably plugged into the front end of the locking plug plate, and the outer ends of the locking sliders on the upper and lower sides of the locking plug plate slide through the outside of the locking frame.

[0016] Preferably, the upper end of the locking bar in the initial state is in an inclined structure that fits the top surface of the docking device body, and by flipping the locking bar backward, the locking slider connected to the traction cable is driven to slide inward synchronously, so that after entering the locking plug plate, the locking frame and the locking plug plate are unlocked and separated from each other.

[0017] Preferably, a correction mechanism is provided on the left side of the plug-in cavity inside the connector body, and the correction mechanism includes a correction protrusion fixedly arranged inside the plug-in cavity, and correction slots are symmetrically opened on the outside of the correction protrusion, and a push cam is rotatably arranged inside the correction protrusion through a bearing.

[0018] Preferably, the correction mechanism includes a correction bracket, and the correction bracket is fixedly installed on the left side of the interior of the docking device body, and the protrusion inside the correction bracket is slidably engaged in the correction slot inside the correction protrusion.

[0019] Preferably, by rotating the push cam inside the correcting protrusion, the outer end of the push cam will abut and expand the front end of the correcting bracket, so that the protrusion inside the correcting bracket and the correcting slot outside the correcting protrusion are disengaged from each other, thereby assisting the connector body and the docking device body to separate from each other.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: the anti-dislocation self-locking connector plug-in structure prevents dislocation during docking through the guide mechanism of the connector body and the docking device body, and prevents the metal contact pin and the metal contact piece from deviating when in contact by the unlockable correction bracket and the correction protrusion, and realizes the locking and unlocking of the connector body and the docking device body through the locking mechanism to avoid mutual detachment due to external force. The specific contents are as follows:

[0021] 1. The front end of the guide base plate contacts the bottom surface of the connector body, and the inclined surface of the guide base plate contacts the inner wall of the guide column during continuous movement, so that the guide column can limit the movement path of the guide base plate and the docking body to prevent misalignment when the connector body and the docking body are plugged in.

[0022] 2. The locking bar rotates backward so that the locking sliders on the upper and lower sides of the locking plug plate can be driven to slide inward synchronously by the traction cable, so that the locking sliders no longer penetrate the locking frame and are stored in the locking plug plate, and the locking frame and the locking plug plate are no longer locked, and then the connector body and the docking device body are pulled out to separate.

[0023] The outer ends of the locking sliders at the upper and lower ends of the side locking plug plate slide through the outside of the locking frame to lock the locking plug plate inside the locking frame, thereby locking and plugging the connector body and the docking device body to prevent them from falling off due to external forces.

[0024] 3. The correction bracket first enters the inside of the plug-in cavity, and its front end slides on the outside of the correction protrusion. When the correction bracket continues to move and dock, the protrusion on the inside of the correction bracket is engaged with the correction slot opened on the outside of the correction protrusion, thereby preventing the metal contact foot from being misaligned and offset when connected to the metal contact piece.

[0025] The cam arranged inside the rotating deflection correction protrusion has its protruding outer end abutting against the front end of the deflection correction bracket and expanding outward, thereby disengaging from the deflection correction slot, and then facilitating the plugging and unplugging separation of the connector body and the docking device body.

Obviously, the implementation regulations described 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.

[0040] See also Figure 1-Figure 12 , the present invention provides the following technical solutions:

[0041] Embodiment 1: In order to solve the problems existing in the use of the existing connector body 1, this embodiment adopts the following technical scheme: a self-locking connector plug-in structure with anti-misalignment, including a connector body 1, and a plug-in cavity 2 opened inside the connector body 1, and metal contact pins 3 are fixedly arranged at equal distances on the upper and lower sides of the plug-in cavity 2; a docking body 4 is arranged at the rear of the connector body 1, and a metal contact piece 5 is fixedly arranged inside the docking body 4; a guide mechanism is arranged on the bottom surface of the docking body 4, and the guide mechanism includes a guide base plate 6, and the rear end of the guide base plate 6 is fixedly installed on the bottom surface of the docking body 4.

[0042] The guide mechanism includes a guide column 8, and the top end of the guide column 8 is fixedly arranged on the left and right sides of the bottom surface of the connector body 1, and the guide mechanism includes a contact arc hook 9, and the contact arc hook 9 is fixedly arranged on the left and right sides of the front end of the guide base plate 6; the guide base plate 6 included in the guide mechanism follows the docking device body 4 and the connector body 1 for plugging, and the outer end of the guide base plate 6 fits and slides on the inner walls of the guide columns 8 on the left and right sides of the bottom surface of the connector body 1, and is limited to the outer wall of the guide column 8 by the contact arc hook 9 at the outer end of the guide base plate 6.

[0043] like Figure 5-Figure 6As shown, when the connector body 1 and the docking body 4 are plugged in, the front end of the docking body 4 and the rear end of the connector body 1 are docked with each other, and then the front end of the guide base plate 6 arranged on the bottom surface of the docking body 4 first contacts with the bottom surface of the connector body 1, and when the movement continues, the inclined structure of the front end of the guide base plate 6 contacts with the inner wall of the guide column 8 on the bottom surface of the connector body 1, so as to limit the moving path of the guide base plate 6 and the docking body 4 through the guide column 8, thereby preventing misalignment when the connector body 1 and the docking body 4 are plugged in.

[0044] Embodiment 2: In order to solve the problems existing in the use of the existing connector body 1, the present embodiment adopts the following technical solution: locking mechanisms are provided on both sides of the docking device body 4, and the locking mechanisms include locking bars 7, and the bottom ends of the locking bars 7 are rotatably provided on the left and right sides of the exterior of the docking device body 4 through torsion springs. The locking mechanism includes a locking plug plate 10, and locking sliders 11 are elastically slidably provided on both the upper and lower sides of the inner front end of the locking plug plate 10, and the outer ends of the locking sliders 11 on both sides slide through the exterior of the front end of the locking plug plate 10, and the symmetrically arranged locking sliders 11 and the bottom ends of the locking bars 7 are connected to each other through a traction cable 12.

[0045] The locking mechanism includes a locking frame 13, and the interior of the locking frame 13 is slidably inserted into the front end of the locking plug plate 10, and the outer ends of the locking sliders 11 on the upper and lower sides of the locking plug plate 10 slide through the outside of the locking frame 13; the upper end of the locking bar 7 in the initial state is in an inclined structure and fits the top surface of the docking device body 4, and after the locking bar 7 is flipped backward, the locking slider 11 connected to the traction cable 12 is driven to slide inward synchronously, so that after entering the interior of the locking plug plate 10, the locking frame 13 and the locking plug plate 10 are unlocked and separated from each other.

[0046] like Figure 2-Figure 3 , Fig.11 As shown, when the connector body 1 and the dock body 4 need to be separated and unlocked, the locking bar 7 above the dock body 4 is manually rotated backward, so that the locking bar 7 drives the locking sliders 11 on the upper and lower sides of the locking plug plate 10 to slide inward synchronously through the traction cable 12, so that the locking slider 11 no longer penetrates the locking frame 13 and is stored in the locking plug plate 10, and then the locking frame 13 and the locking plug plate 10 are no longer locked, and then the connector body 1 and the dock body 4 are pulled out to achieve separation.

[0047] Furthermore, the connector body 1 and the docking body 4 in the connected state slide through the outer ends of the locking sliders 11 at the upper and lower ends of the side locking plate 10 to lock the locking plate 10 inside the locking frame 13, thereby locking the connector body 1 and the docking body 4 to prevent separation due to external force.

[0048] Embodiment 3: In order to solve the problems existing in the use of the existing connector body 1, this embodiment adopts the following technical scheme: a correction mechanism is provided on the left side of the plug-in cavity 2 inside the connector body 1, and the correction mechanism includes a correction protrusion 14 fixedly arranged inside the plug-in cavity 2, and the correction protrusion 14 is symmetrically provided with a correction slot 15 on the outside, and a push cam 16 is rotatably provided inside the correction protrusion 14 through a bearing.

[0049] The correction mechanism includes a correction bracket 17, and the correction bracket 17 is fixedly installed on the left side of the inside of the docking device body 4, and the protrusion inside the correction bracket 17 is slidably engaged in the correction slot 15 inside the correction protrusion 14; by rotating the push cam 16 inside the correction protrusion 14, the outer end of the push cam 16 will resist and expand the front end of the correction bracket 17, so that the protrusion inside the correction bracket 17 and the correction slot 15 outside the correction protrusion 14 are disengaged from each other, thereby assisting the connector body 1 and the docking device body 4 to separate from each other.

[0050] like Figure 7-10 As shown, when the connector body 1 and the docking device body 4 are plugged in, the correcting bracket 17 arranged inside the docking device body 4 first enters the interior of the plug-in cavity 2, and at the same time, the front end of the correcting bracket 17 slides on the outside of the correcting protrusion 14, and when the docking is continuously moved, the protrusion on the inner side of the correcting bracket 17 is engaged with the correcting groove 15 provided on the outside of the correcting protrusion 14, thereby preventing the metal contact pin 3 from being misaligned and offset when connected with the metal contact piece 5.

[0051] Furthermore, by rotating the abutting cam 16 arranged inside the correcting protrusion 14, it is rotated from a vertical state to a horizontal state, and its protruding outer end abuts against the left and right sides of the front end of the correcting bracket 17, so that the front end of the correcting bracket 17 simultaneously expands outward, and then disengages from the engagement with the correcting slot 15, and then facilitates the plugging and unplugging separation of the connector body 1 and the docking device body 4.
