Description

Technical Field

[0001] The utility model relates to the technical field of connectors, and more specifically, to a connector. Background Art

[0002] In the process of laying and applying wires and cables, due to product design and process requirements, it is often necessary not only to connect two wires to achieve connection and conduction to establish electrical connection, but also to be able to be disassembled for easy assembly, maintenance and replacement. Such situations are usually achieved by connectors, which usually include male and female ends: through the docking between the male and female ends, the connector achieves electrical connection, allowing current and signals to flow between the wires; through the disassembly between the male and female ends, assembly, maintenance and replacement are achieved. There are generally two ways to connect the male and female ends of connectors on the market: one is direct plug-in without a snap-on connection, in which the conductive sockets on the male and female ends are connected to each other. The disadvantage of this method is that it cannot prevent pulling and retreat, and is easy to detach and disconnect, and requires additional insulating tape for binding and fixing; the other method is to provide a snap-on and a snap-on hole on the male and female ends respectively, and use a snap-on connection. After insertion, the snap-on is snapped into the snap-on hole, and the snap-on hole abuts against the snap-on to prevent pulling and retreat. When disassembling, the snap-on is pressed in the snap-on hole to separate the snap-on from the snap-on hole, and then the male and female ends are disassembled to achieve separation.

[0003] However, for the snap-on connector, in order to facilitate the buckle to slide into the hole, the buckle is generally flush with the hole or slightly protrudes from the hole after being inserted into the hole. Moreover, due to the limited size of the connector, it is impossible to set a larger hole, so the size of the hole is limited. Correspondingly, the size of the buckle is also limited, resulting in a limited pressing force point of the buckle. When the male end is connected to the female end, the buckle is tightly in contact with the hole. It is difficult to press the buckle flush with the hole or slightly protruding from the hole. It is difficult for the operator to press the buckle out of the hole with his fingertips or nails, and it is often necessary to find a small stick to assist in pressing. Such a connector cannot achieve convenient separation of the male end and the female end, and the separation process is likely to cause damage to the connector. Utility Model Content

[0004] The purpose of the utility model is to overcome the disadvantage of the existing connector that it is difficult to operate the buckle that is flush with and tightly abutted against the buckle hole from the buckle hole, and to provide a connector. The utility model does not require a specific force application point, and only needs to apply force on the entire elastic pressure plate to quickly and conveniently separate the first terminal head from the second terminal head, which is simple and efficient to operate.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A connector comprises a first terminal and a second terminal which can be connected to each other. An elastic buckle block is connected to the end of the first terminal. The elastic buckle block is snap-connected to the second terminal. The second terminal is provided with an elastic pressure plate. After the elastic pressure plate is pressed, the elastic buckle block is deformed and separated from the second terminal.

[0007] It should be noted that after the first terminal and the second terminal of the utility model are plugged in, the two can be male and female ends of each other to achieve mutual alignment and plugging. At this time, the elastic buckle block is connected with the second terminal by snapping, realizing the function of anti-pulling and anti-retreat, and the first terminal and the second terminal are not easily detached. When it is necessary to release the connection between the first terminal and the second terminal, the elastic pressure plate is pressed, the elastic pressure plate is deformed and gradually abuts against the elastic buckle block to start transmitting pressure, the elastic buckle block is also deformed under the abutting force, the elastic pressure plate and the elastic buckle block are deformed and move downward until the elastic buckle block is detached from the second terminal, thereby realizing the disassembly and separation of the first terminal and the second terminal. The utility model is different from the traditional snap-on connector. Since the area of ​​the buckle hole is limited and the structure where the buckle hole is located is a hard structure, force can only be applied to the convex buckle in the buckle hole during disassembly. The force application range is small, which makes the operation difficult. The utility model applies force by the indirect effect of pressing the elastic pressure plate to deform and abut against the elastic buckle block. Therefore, there is no need for a specific force application point, and it is only necessary to apply force to the entire elastic pressure plate. The shape and area of ​​the elastic pressure plate can be designed according to the shape of the second terminal head. In this way, a larger contact area can be designed as much as possible, thereby improving the convenience of pressing.

[0008] It should also be noted that the first terminal and the second terminal are respectively provided with conductive terminals or signal transmission terminals to achieve the conductive function or signal transmission function after docking. The structure of the conductive terminals or signal transmission terminals is prior art and will not be elaborated.

[0009] Furthermore, a pressing window is provided on the side wall of the second terminal head, and the elastic pressing plate is connected to the pressing window. Since the second terminal head is small in size, the pressing window is directly provided on the side wall of the second terminal head and the elastic pressing plate is connected to the pressing window, so that the spatial layout of the second terminal head can be optimized, so that the elastic pressing plate can directly abut the elastic buckle block after deformation, thereby improving the pressure transmission efficiency, and the structure is compact and reasonable. For the injection molding production of the second terminal head, it is easy to process and shape, while reducing the production cost.

[0010] Furthermore, after the first terminal and the second terminal are plugged into each other, the upper surface of the elastic buckle block and the lower surface of the elastic pressure plate are in contact with each other. In this way, after the first terminal and the second terminal are plugged into each other, the elastic buckle blocks and the elastic pressure plate of the two can fit tightly, the structure is compact and the layout is reasonable, and the connection strength and clamping effect of the two are improved.

[0011] Furthermore, the elastic pressure plate includes a connecting portion and a pressing portion, the connecting portion is connected to the side wall of the second terminal head, and the distance between the connecting portion and the end face of the second terminal head is smaller than the distance between the pressing portion and the end face of the second terminal head. In this way, when the elastic pressure plate is pressed, the deformation trend of the elastic pressure plate is that the suspended pressing portion is deformed first, and the suspended pressing portion is the side away from the opening end face of the air avoidance groove, so that the pressing portion of the elastic pressure plate can first contact the end of the elastic buckle block, causing the elastic buckle block to deform immediately and thus come out, which can save effort when pressing and improve the effectiveness of pressing and coming out.

[0012] As a preferred solution, the elastic buckle block is provided with a convex buckle, and the elastic pressure plate is also provided with a buckle hole for the convex buckle to be engaged.

[0013] As another preferred solution, a convex buckle is provided on the elastic buckle block, and a buckle hole for the convex buckle to be snapped into is also provided on the side wall of the second terminal.

[0014] In this way, the specific method of snap-connecting the elastic buckle block with the second terminal is to snap-connect the convex buckle and the buckle hole in a form of aligned snap-connection, which has a simple and effective structure and plays an anti-pull and anti-retreat effect.

[0015] Furthermore, the button hole is provided on the elastic pressing plate and is located between the connecting portion and the pressing portion. The button hole is provided on the elastic pressing plate, and when the elastic pressing plate is deformed, the button hole will also be twisted immediately along with the elastic pressing plate, thereby improving the effectiveness and efficiency of the removal.

[0016] Furthermore, the pressing portion is further provided with a pressing protrusion that is highly protruded from the side wall surface of the second terminal head. The pressing protrusion enables the operator to quickly find the force application position, improve the disassembly efficiency and simplify the operation difficulty.

[0017] Furthermore, the pressing protrusion is also provided with anti-slip grooves. The pressing protrusion is also provided with anti-slip grooves. It should be noted that the anti-slip grooves can be designed as regular or irregular concave and convex patterns; the anti-slip grooves can also be designed in the style of Chinese or English letters, including but not limited to the styles of "press", "press" or "press".

[0018] Furthermore, the protruding buckle includes a guiding portion and a clamping portion which are connected to each other, the surface height of the guiding portion relative to the elastic buckle block gradually increases, the clamping portion abuts against the buckle hole, and the distance between the guiding portion and the end face of the first terminal is not less than the distance between the clamping portion and the end face of the first terminal.

[0019] It should be noted that the guiding portion can be an arc surface or an inclined surface that forms a certain angle with the surface of the elastic buckle block. During the plug-in process of the first terminal and the second terminal, the arc surface or the inclined surface first contacts the end face side wall of the second terminal during plug-in. The arc surface or the inclined surface has a certain inclination, which can facilitate the first terminal to better enter the second terminal, and play a certain guiding role; the clamping portion can be a vertical surface that is perpendicular to the surface of the elastic buckle block. After the first terminal and the second terminal are clamped into place, without applying force, the vertical surface will firmly abut against the buckle hole, which plays a very good anti-pull and anti-retreat role, thereby ensuring the effective clamping of the first terminal and the second terminal.

[0020] Furthermore, the first terminal includes a plug-in boss located at the end, and the axis of the plug-in boss is parallel to the axis of the elastic buckle block; the second terminal includes a plug-in slot opened at the end, and the plug-in boss and the plug-in slot are detachably plugged. In this way, the first terminal is used as a male end and the second terminal is used as a female end to achieve mutual plug-in, and the conductive terminal or signal transmission terminal can be respectively arranged in the plug-in boss and the plug-in slot to achieve basic conductive function or signal transmission function.

[0021] Furthermore, a clearance groove is provided at the end of the second terminal head for the elastic buckle block to enter and exit, and the clearance groove includes a first clearance portion and a second clearance portion which are interconnected, the width of the clearance surface of the first clearance portion is greater than the width of the elastic pressure plate, and the width of the clearance surface of the second clearance portion is greater than the width of the elastic buckle block; the second clearance portion is interconnected with the plug-in slot.

[0022] It should be noted that in order to ensure that the elastic pressure plate and the elastic buckle block can be deformed and moved downward smoothly, the first avoidance portion and the second avoidance portion need to be able to accommodate the elastic pressure plate and the elastic buckle block to avoid air when they are deformed and moved downward. In addition, the second avoidance portion is connected with the plug-in slot, which can realize the circulation of airflow. During the plug-in process of the first terminal and the second terminal, the gas in the plug-in slot can be discharged after reaching the pressing window along the second avoidance portion and the first avoidance portion, thereby improving the smoothness of the plug-in process. On the other hand, the structural space of the connector is limited, and reasonable connection can simplify the structure and reduce production costs.

[0023] It should also be noted that the definitions of length and width in the present utility model are: the length direction is the plug-in direction of the first terminal and the second terminal, and the width direction is the direction perpendicular to the length direction, that is, the direction perpendicular to the plug-in direction of the first terminal and the second terminal is the width direction; the width direction of the first avoidance portion and the second avoidance portion is the width direction perpendicular to the plug-in direction of the first terminal and the second terminal.

[0024] Compared with the prior art, the beneficial effects of the utility model are:

[0025] (1) After the first terminal and the second terminal of the utility model are plugged in, the two can be mutually male and female ends to achieve mutual alignment and plugging. At this time, the elastic buckle block is connected with the second terminal by snapping, realizing the function of anti-pulling and anti-retraction. The first terminal and the second terminal are not easy to be separated. When it is necessary to release the connection between the first terminal and the second terminal, by pressing the elastic pressure plate, the elastic pressure plate is deformed and gradually abuts against the elastic buckle block to start transmitting pressure. The elastic buckle block is also deformed under the abutting force. The elastic pressure plate and the elastic buckle block are deformed and move downward until the elastic buckle block is separated from the second terminal, thereby realizing the disassembly and separation of the first terminal and the second terminal.

[0026] (2) The utility model applies force by the indirect effect of pressing the elastic pressure plate to deform and abut against the elastic buckle block, so there is no need for a specific force application point, and it is sufficient to apply force on the entire elastic pressure plate. The shape and area of ​​the elastic pressure plate can be designed according to the shape of the second terminal head, so that a larger contact area can be designed as much as possible, thereby improving the convenience of pressing.

[0037] Example 1

[0038] like Figure 1 to Figure 2 As shown, a connector includes a first terminal 1 and a second terminal 2 which can be connected to each other. An elastic buckle block 12 is connected to the end of the first terminal 1. The elastic buckle block 12 is snap-connected to the second terminal 2. The second terminal 2 is provided with an elastic pressure plate 23. After pressing the elastic pressure plate 23, the elastic buckle block 12 is deformed and separated from the second terminal 2.

[0039] like Figure 3 As shown, a pressing window is provided on the side wall of the second terminal 2, and the elastic pressing plate 23 is connected in the pressing window. Since the second terminal 2 is small in size, a pressing window is directly provided on the side wall of the second terminal 2 and the elastic pressing plate 23 is connected to the pressing window, so that the spatial layout of the second terminal can be optimized, so that the elastic pressing plate 23 can directly abut the elastic buckle block 12 after deformation, thereby improving the pressure transmission efficiency, and the structure is compact and reasonable. For the injection molding production of the second terminal 1, it is easy to process and shape, while reducing the production cost.

[0040] In this embodiment, after the first terminal 1 and the second terminal 2 are plugged into each other, the upper surface of the elastic buckle block 12 and the lower surface of the elastic pressure plate 23 are in contact with each other. In this way, after the first terminal 1 and the second terminal 2 are plugged into each other, the elastic buckle block 12 and the elastic pressure plate 23 of the two can fit tightly, the structure is compact and the layout is reasonable, and the connection strength and clamping effect of the two are improved.

[0041] like Figure 3As shown, the elastic pressing plate 23 includes a connecting portion and a pressing portion, the connecting portion is connected to the side wall of the second terminal head 2, and the distance between the connecting portion and the end face of the second terminal head 2 is smaller than the distance between the pressing portion and the end face of the second terminal head 2. In this way, when the elastic pressing plate 23 is pressed, the deformation trend of the elastic pressing plate 23 is that the suspended pressing portion is deformed first, and the suspended pressing portion is the side away from the opening end face of the air-avoiding groove 25. In this way, the pressing portion of the elastic pressing plate 23 can first contact the end of the elastic buckle block 12, causing the elastic buckle block 12 to deform immediately and thus come out, which can save effort when pressing and improve the effectiveness of pressing and coming out.

[0042] like Figure 1 As shown, the elastic buckle block 12 is provided with a convex buckle 13, and the elastic pressure plate 23 is also provided with a buckle hole 24 for the convex buckle 13 to be engaged. The specific method of the buckle connection between the elastic buckle block 12 and the second terminal 2 is to use the convex buckle 13 and the buckle hole 24 to be aligned and engaged, which has a simple and effective structure and has an anti-pull and anti-retreat effect.

[0043] In this embodiment, the maximum bottom area of ​​the convex buckle 13 is smaller than the opening area of ​​the buckle hole 24. It should be noted that the bottom area of ​​the convex buckle 13 is the area of ​​the connecting surface between the convex buckle 13 and the elastic buckle block 12, ensuring that the convex buckle 13 can be inserted into the buckle hole 24 and snapped into place.

[0044] like Figure 3 As shown, the button hole 24 is formed on the elastic pressing plate 23 and is located between the connecting portion and the pressing portion. The button hole 24 is formed on the elastic pressing plate 23. When the elastic pressing plate 23 is deformed, the button hole 24 will also be twisted immediately along with the elastic pressing plate 23, thereby improving the effectiveness and efficiency of the removal.

[0045] like Figure 2 and Figure 3 As shown, the pressing portion is further provided with a pressing protrusion 231 which is highly protruded from the side wall surface of the second terminal 2. The pressing protrusion 231 enables the operator to quickly find the force application position, improve the disassembly efficiency and simplify the operation difficulty.

[0046] like Figure 3 As shown, the pressing protrusion 231 is also provided with an anti-slip pattern 232 .

[0047] like Figure 3 As shown, in this embodiment, the anti-slip pattern 232 is designed in the style of English letters, indicating the "press" style.

[0048] like Figure 1 to Figure 2As shown, the first terminal 1 includes a plug-in boss 11 at the end, and the axis of the plug-in boss 11 is parallel to the axis of the elastic buckle block 12; the second terminal 2 includes a plug-in slot 21 opened at the end, and the plug-in boss 11 and the plug-in slot 21 are detachably plugged. In this way, the first terminal 1 is used as a male end, and the second terminal 2 is used as a female end to achieve mutual plugging, and the conductive terminals are respectively arranged in the plug-in boss 11 and the plug-in slot 21 to achieve basic conductive functions.

[0049] like Figure 1 and Figure 2 As shown, in this embodiment, an annular groove is provided on the outer periphery of the first wiring head 1 and the second wiring head 2 to facilitate the operator to hold the wiring head to prevent slipping.

[0050] In this embodiment, the shape of the plug slot 21 matches the shape of the plug boss 11. During the plugging process of the first terminal 1 and the second terminal 2, since the shape of the plug slot 21 matches the shape of the plug boss 11, there will not be too much space between the plug slot 21 and the plug boss 11, so they can guide each other during the plugging process, and after being plugged in place, they can also play a stabilizing role, and are not prone to skewing and swinging.

[0051] The advantage of the present application is that after the first terminal 1 and the second terminal 2 are plugged in, the two can be male and female ends of each other to achieve mutual alignment and plugging. At this time, the convex buckle 13 of the elastic buckle block 12 is snapped into the buckle hole 24 of the elastic pressure plate 23 to achieve the function of anti-pulling and anti-retreat. The first terminal 1 and the second terminal 2 are not easy to be separated. When it is necessary to release the connection between the first terminal 1 and the second terminal 2, by pressing the elastic pressure plate 23, the elastic pressure plate 23 is deformed in the pressing window and abuts against the elastic buckle block 12 to start transmitting pressure. The elastic buckle block 12 is also deformed under the abutting force. The elastic pressure plate 23 and the elastic buckle block 12 are deformed and move downward until the convex buckle 13 on the elastic buckle block 12 is disengaged from the buckle hole 24 of the elastic pressure plate 23, thereby achieving the disassembly and separation of the first terminal 1 and the second terminal 2. The present application is different from the traditional snap-on connector. Since the area of ​​the buckle hole 24 is limited and the structure where the buckle hole 24 is located is a hard structure, force can only be applied to the convex buckle 13 in the buckle hole 24 during disassembly. The force application range is small, which makes the operation difficult. The present invention sets the buckle hole 24 on the elastic pressure plate, and applies force by the indirect effect of pressing the elastic pressure plate 23 to deform and abut against the elastic buckle block 12. Therefore, there is no need for a specific force application point, and only needs to apply force on the entire elastic pressure plate 23. The shape and size of the pressing window can be designed according to the size of the side wall area of ​​the second terminal head 2, and the shape and area of ​​the elastic pressure plate are also designed according to the shape of the pressing window. In this way, a larger contact area can be designed as much as possible to improve the convenience of pressing.

[0052] Example 2

[0053] This embodiment is similar to Embodiment 1, except that:

[0054] In this embodiment, the buckle hole 24 is provided on the side wall of the second terminal 2, and the buckle hole 24 is engaged with the convex buckle 13. The specific method of the buckle connection between the elastic buckle block 12 and the second terminal 2 is to engage the convex buckle 13 and the buckle hole 24 in a positional engagement, which has a simple and effective structure and has an anti-pull and anti-retraction effect.

[0055] The other structures and principles of this embodiment are the same as those of Embodiment 1.

[0056] Example 3

[0057] This embodiment is similar to Embodiment 1, except that in this embodiment:

[0058] like Figure 4 As shown, the end of the second terminal 2 is also provided with an escape groove 25 for the elastic buckle block 12 to enter and exit, and the escape groove 25 includes a first escape portion 251 and a second escape portion 252 that are interconnected, the width of the escape surface of the first escape portion 251 is greater than the width of the elastic pressure plate 23, and the width of the escape surface of the second escape portion 252 is greater than the width of the elastic buckle block 12. In order to ensure that the elastic pressure plate 23 and the elastic buckle block 12 can be deformed and moved downward smoothly, the first escape portion 251 and the second escape portion 252 need to be able to accommodate the elastic pressure plate 23 and the elastic buckle block 12 to pass through when they are deformed and moved downward.

[0059] like Figure 4 As shown, the second avoidance portion 252 is interconnected with the plug-in slot 21. The second avoidance portion 252 and the plug-in slot 21 are interconnected. On the one hand, the airflow can be realized. During the plug-in process of the first terminal 1 and the second terminal 2, the gas in the plug-in slot 21 can flow along the second avoidance portion 252 and the first avoidance portion 251 to the pressing window and be discharged, thereby improving the smoothness of the plug-in process; on the other hand, the structural space of the connector is limited, and reasonable connection can simplify the structure and reduce production costs.

[0060] In this embodiment, the plug-in slot 21 and the avoidance slot 25 are separated by a pair of symmetrical partitions, the two partitions are not connected to each other, the middle space of the two partitions is the second avoidance portion 252, the upper space of the two partitions is the first avoidance portion 251, and the lower space of the two partitions is the plug-in slot 21, wherein the upper and lower positions of the upper and lower spaces of the two partitions are Figure 4 direction shown.

[0061] In this embodiment, the length and width are defined as follows: the length direction is the plug-in direction of the first terminal 1 and the second terminal 2, and the width direction is the direction perpendicular to the length direction, that is, the direction perpendicular to the plug-in direction of the first terminal 1 and the second terminal 2 is the width direction; the width direction of the first avoidance portion 251 and the second avoidance portion 252 is the width direction perpendicular to the plug-in direction of the first terminal 1 and the second terminal 2.

[0062] The other structures and principles of this embodiment are the same as those of Embodiment 1.

[0063] Example 4

[0064] This embodiment is similar to Embodiment 3, except that in this embodiment:

[0065] like Figure 5 and Figure 6 As shown, the convex buckle 13 includes a guide portion 131 and a clamping portion 132 connected to each other, the guide portion 131 gradually increases in height relative to the surface of the elastic buckle block 12, the clamping portion 132 abuts against the buckle hole 24, and the distance between the guide portion 131 and the end face of the first terminal 1 is not less than the distance between the clamping portion 132 and the end face of the first terminal 1.

[0066] In this embodiment, the guide portion 131 may be an inclined surface that forms a certain angle with the surface of the elastic buckle block 12. During the plugging process between the first terminal 1 and the second terminal 2, the inclined surface first contacts the end surface side wall of the second terminal 2 during the plugging process. The inclined surface has a certain slope that can facilitate the first terminal 1 to better enter the second terminal 2, thus playing a certain guiding role.

[0067] In this embodiment, the clamping portion 132 can be a vertical surface perpendicular to the surface of the elastic buckle block 12. After the first terminal 1 and the second terminal 2 are clamped into place, without applying force, the vertical surface will firmly abut against the buckle hole 24, playing a very good anti-pulling and anti-retreat role, thereby ensuring the effective clamping of the first terminal 1 and the second terminal 2.

[0068] The other structures and principles of this embodiment are the same as those of Embodiment 3.
