Due to improper insertion or external force, the plug terminal is easy to detach from the connector body, resulting in poor connection stability and affecting the normal operation of electrical appliances. [Summary of the Invention]

[0004] This application provides a connector to solve the technical problem that existing connectors are prone to disconnection of the plug terminals from the connector body due to improper plugging or external force, resulting in poor connection stability and affecting the normal operation of electrical appliances.

[0005] In a first aspect, embodiments of this application provide a connector, including: a connector base having a receiving cavity, the connector base having a first end and a second end disposed opposite to each other, the first end of the connector base being provided with a first anti-retraction mechanism; and a plug-in terminal including a terminal body, one end of the terminal body near the connector base being disposed in the receiving cavity of the connector base, the terminal body being provided with a second anti-retraction mechanism connected to the first anti-retraction mechanism.

[0006] In one possible implementation, the first anti-reverse mechanism includes a first boss, one end of which is connected to the connecting seat, and the end of the first boss away from the connecting seat extends along a first direction; the second anti-reverse mechanism includes an elastic cantilever, on which a second boss is provided, and the side of the second boss facing the second end of the connecting seat is opposite to the side of the first boss away from the second end of the connecting seat in the first direction.

[0007] In one possible implementation, the elastic cantilever has a connecting end and a suspended end, the connecting end of the elastic cantilever being connected to the terminal body, and the suspended end of the elastic cantilever being suspended.

[0008] In one possible implementation, a wedge-shaped surface is provided on the side of the first boss away from the second boss.

[0009] In one possible implementation, there are two first bosses and two second bosses corresponding to the first bosses, with the two second bosses respectively located on both sides of the elastic cantilever.

[0010] In one possible implementation, a third protrusion is provided at the first end of the connector, and the third protrusion and the first anti-reverse mechanism are disposed opposite each other in the third direction; a fourth protrusion is provided on the terminal body, and the fourth protrusion and the second anti-reverse mechanism are disposed opposite each other in the third direction, and the side of the fourth protrusion away from the second end of the connector abuts against the side of the third protrusion facing the second end of the connector.

[0011] In one possible implementation, the connector is cylindrical, and a cover is provided at the first end of the connector. The cover has an opening that communicates with the accommodating cavity. The opening has a first width in a second direction, and the terminal body has a second width in a second direction. The first width and the second width are adapted to each other.

[0012] In one possible implementation, the inner sidewall of the connecting seat is provided with a guide platform, and the thickness of the guide platform in the radial direction of the connecting seat gradually increases along the direction close to the second end of the connecting seat.

[0017] The technical solution provided in this application embodiment has the following advantages compared with the prior art: In the manufacturing and use of the connector provided in this application embodiment, the plug terminal moves from the first end of the connector base through the receiving cavity to the second end of the connector base until the plug terminal is installed in place. At this time, the side of the plug terminal with the metal pin is exposed for connection with external electrical appliances. During the connection with external electrical appliances, the plug terminal is subjected to a squeezing force towards the rear end. By utilizing the reverse force of the first anti-reverse mechanism on the second anti-reverse mechanism, the plug terminal can be prevented from moving excessively towards the rear end, thereby ensuring the stability of the connection between the connector and the external electrical appliance. Simultaneously, during the operation of the connector and the electrical appliance, it can also prevent the plug terminal from being affected by vibration and detaching from the connector base, further ensuring the connection stability and operational reliability of the connector.

Implementation Method

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] The following disclosure provides many different embodiments or examples for implementing different structures of this application. To simplify the disclosure of this application, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0023] For ease of description, spatial relative terms may be used in the text to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or movement change, these directional indications will change accordingly. For example, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0024] In order to solve the technical problem that the plug terminals are easy to detach from the connector body due to improper plugging or external force, resulting in poor connection stability and affecting the normal operation of electrical appliances, this application provides a connector that can prevent the plug terminals from moving excessively to the rear end under force, thereby ensuring the stability of the connection between the connector and external electrical appliances.

[0025] Figure 1 shows a connector provided in an embodiment of this application, including a connector 1 and a plug terminal 2. The connector 1 is provided with a receiving cavity 11. The connector 1 has a first end 101 and a second end 102 disposed opposite to each other. The first end 101 of the connector 1 is provided with a first anti-retraction mechanism 12. The plug terminal 2 includes a terminal body 21. One end of the terminal body 21 near the connector 1 is disposed in the receiving cavity 11 of the connector 1. The terminal body 21 is provided with a second anti-retraction mechanism 22 connected to the first anti-retraction mechanism 12.

[0026] Optionally, a wire (not shown in the figure) is provided on the terminal body 21, and a metal needle 211 electrically connected to the wire is provided on the terminal body 21. One end of the terminal body 21 with the metal needle 211 extends from the second end 102 of the connector 1 through the receiving cavity 11 of the connector 1, and then extends from the first end 101 of the connector 1, so that the metal needle 211 is exposed, which is convenient for connection with external electrical appliances.

[0027] For ease of explanation and understanding, the first end 101 of the connector 1 is referred to as the front end, and the second end 102 of the connector 1 is referred to as the rear end. It can be understood that, as shown in Figure 2, during the manufacturing and use of the connector, the plug terminal 2 moves from the first end 101 of the connector 1 through the receiving cavity 11 to the second end 102 of the connector 1 until the plug terminal 2 is installed in place. At this time, the side of the plug terminal 2 with the metal pin 211 is exposed for connection with external electrical appliances. As shown in Figure 3, during the connection with external electrical appliances, the plug terminal 2 is subjected to a pressing force F1 towards the rear end. The first anti-reverse mechanism 12's counterforce F2 against the second anti-reverse mechanism 22 prevents the plug terminal 2 from moving excessively towards the rear end, thereby ensuring the stability of the connection between the connector and the external electrical appliance. Simultaneously, during the operation of the connector and the electrical appliance, it also prevents the plug terminal 2 from being affected by vibration and detaching from the connector 1, further ensuring the connection stability and operational reliability of the connector.

[0028] It should be noted that the connector 1 can be made of insulating material.

[0029] In some embodiments, as shown in Figures 4 and 6, the first anti-reverse mechanism 12 includes a first boss 121, one end of which is connected to the connecting seat 1, and the end of the first boss 121 away from the connecting seat 1 extends along a first direction; the second anti-reverse mechanism 22 includes an elastic cantilever 221, on which a second boss 222 is provided, and the side of the second boss 222 facing the second end 102 of the connecting seat 1 is opposite to the side of the first boss 121 away from the second end 102 of the connecting seat 1 in the first direction.

[0030] Optionally, the first direction may be the X direction shown in the figure.

[0031] It is understood that the elastic cantilever 221 has a first state of initial free extension and a second state of being pressed down. The plug terminal 2 moves from the second end 102 of the connector 1 to the first end 101 of the connector 1 until the plug terminal 2 is installed in place, at which point the elastic cantilever 221 switches from the first state to the second state. In the second state, the side of the second boss 222 facing the second end 102 of the connector 1 and the side of the first boss 121 away from the second end 102 of the connector 1 are arranged opposite each other in the X direction. If the plug terminal 2 is subjected to a pressing force F1 towards the rear end or external vibration, the force of the first boss 121 on the second boss 222 can prevent the plug terminal 2 from moving excessively towards the rear end under the pressing force F1, thereby ensuring the stability of the connection between the connector and the external electrical appliance.

[0032] Of course, after the plug-in terminal 2 is installed in place, the side of the second protrusion 222 facing the second end 102 of the connector 1 and the side of the first protrusion 121 away from the second end 102 of the connector 1 can be set to abut against each other, or they can not contact each other. Preferably, after the plug-in terminal 2 is installed in place, there is a certain gap between the side of the second protrusion 222 facing the second end 102 of the connector 1 and the side of the first protrusion 121 away from the second end 102 of the connector 1.

[0033] Further, as shown in FIG6, the elastic cantilever 221 has a connecting end 2211 and a suspended end 2212. The connecting end 2211 of the elastic cantilever 221 is connected to the terminal body 21, and the suspended end 2212 of the elastic cantilever 221 is suspended.

[0034] In the second state, the suspended end 2212 of the elastic cantilever 221 is pressed down by the squeezing force of the inner wall of the connecting seat 1. When the squeezing force is removed (i.e., the plug-in terminal 2 disengages from the connecting seat 1), the suspended end 2212 of the elastic cantilever 221 returns to the initial free extension state. Therefore, the elastic cantilever 221 has a certain elasticity, that is, it has the ability to return to the initial free extension state. Similarly, since the second boss 222 is connected to the elastic cantilever 221, the second boss 222 can change with the state of the elastic cantilever 221, and the second boss 222 also has a certain elasticity.

[0035] In some embodiments, as shown in FIG5, a wedge-shaped surface 1211 is provided on the side of the first boss 121 away from the second boss 222.

[0036] Specifically, during the process of the plug-in terminal 2 moving from the second end 102 of the connector 1 to the first end 101 of the connector 1, the terminal body 21 moves along the wedge surface 1211. The wedge surface 1211 of the first boss 121 can guide and position the terminal body 21 so that the plug-in terminal 2 can be installed in place.

[0037] In one embodiment, two first protrusions 121 are provided, and two second protrusions 222 are provided one-to-one with the first protrusions 121. The two second protrusions 222 are symmetrically arranged on both sides of the elastic cantilever 221, so that after the plug terminal 2 is installed in place, if the plug terminal 2 is subjected to compressive force, the two first protrusions 121 can respectively abut against the corresponding second protrusions 222, which plays a role in preventing the plug terminal 2 from deviating from or detaching from the connector 1, and further improving the connection stability of the connector.

[0038] In some embodiments, referring to Figures 7 and 8, the first end 101 of the connector 1 is provided with a third protrusion 13, the third protrusion 13 and the first anti-retraction mechanism 12 are disposed opposite each other in the third direction, and the two are respectively located on opposite sides of the terminal body 21; the terminal body 21 is provided with a fourth protrusion 212, the fourth protrusion 212 and the second anti-retraction mechanism 22 are disposed opposite each other in the third direction, and the side of the fourth protrusion 212 away from the second end 102 of the connector 1 abuts against the side of the third protrusion 13 facing the second end 102 of the connector 1.

[0039] Optionally, the third direction may be the Z direction shown in the figure.

[0040] It is understood that the plug terminal 2 moves from the first end 101 of the connector 1 through the receiving cavity 11 to the second end 102 of the connector 1. The side of the fourth protrusion 212 away from the second end 102 of the connector 1 abuts against the side of the third protrusion 13 facing the second end 102 of the connector 1. At this time, the plug terminal 2 is installed in place, and the side of the plug terminal 2 with the metal pin 211 is exposed for connection with external electrical appliances. As shown in Figure 8, if the plug terminal 2 is subjected to a pressing force F3 towards the front end, the reverse force F4 of the third protrusion 13 on the fourth protrusion 212 can prevent the plug terminal 2 from moving towards the front end under force, thereby ensuring the connection stability of the plug terminal 2.

[0041] In some embodiments, the connector 1 is cylindrical, and the first end 101 of the connector 1 is provided with a cover 14. The cover 14 is provided with an opening 141 that communicates with the accommodating cavity 11. The opening 141 has a first width in the second direction, and the terminal body 21 has a second width in the second direction. The first width and the second width are adapted to each other.

[0042] Optionally, the second direction may be the Y direction shown in the figure.

[0043] Specifically, as shown in FIG. 7, the opening 141 may be arranged in a "convex" shape to match the shape of the plug-in terminal 2, and at the same time facilitate the passage of the elastic cantilever 221 of the plug-in terminal 2. Through the connection between the opening 141 of the cover 14 and the terminal body 21, the plug-in terminal 2 is installed in place.

[0044] In some embodiments, as shown in FIG. 5, a guiding platform 15 is provided on the inner side wall of the connection base 1. The thickness of the guiding platform 15 in the radial direction of the connection base 1 gradually increases in the direction close to the second end 102 of the connection base 1 until the guiding platform 15 is flush with the opening 141.

[0045] During the process of the plug-in terminal 2 moving from the first end 101 of the connection base 1 through the accommodating cavity 11 to the second end 102 of the connection base 1, the guiding platform 15 plays a guiding role on the plug-in terminal 2, causing the plug-in terminal 2 to move along the guiding platform 15 towards the opening 141 until the fourth boss 212 of the plug-in terminal 2 abuts against the third boss 13 of the connection base 1, and至此 the installation is in place.

[0046] Until the plug-in terminal 2 is installed in place, at this time, the side of the plug-in terminal 2 with the metal pins 211 is exposed for connection with an external electrical appliance.

[0047] Furthermore, a plurality of guiding platforms 15 are provided, and the plurality of guiding platforms 15 are distributed circumferentially along the connection base 1. Optionally, two of the guiding platforms 15 are oppositely arranged in the second direction, making the movement process of the plug-in terminal 2 smoother, and at the same time playing an anti-fooling role to prevent the installation direction of the plug-in terminal 2 from being incorrect.

[0048] In some embodiments, as shown in FIG. 5, a plug 16 is provided at the second end 102 of the connection base 1. The plug 16 is provided with a first through hole 161 communicating with the accommodating cavity 11, and the first through hole 161 facilitates the passage of the wire of the plug-in terminal 2.

[0049] In some embodiments, as shown in FIGS. 9 and 10, the connector further includes a second sleeve 4. The second sleeve 4 is sleeved on the second end 102 of the connection base 1, and the second sleeve 4 is provided with a second through hole 41 corresponding to the first through hole 161. Specifically, a first thread is provided on the inner side wall of the second sleeve 4, and a second thread adapted to the first thread is provided on the outer side wall of the connection base 1 so that the second sleeve 4 can be installed on the connection base 1, and the second sleeve 4 plays a role in waterproofing and dustproofing.

[0050] In some embodiments, the connector further includes a first sleeve 3, which is snapped onto the first end 101 of the connector 1 and covers the periphery of the plug terminal 2. The first end 101 of the connector 1 is provided with a first buckle 17 along its circumference, and the end of the first sleeve 3 facing the connector 1 is provided with a second buckle 31 connected to the first buckle 17. The first sleeve 3 is installed on the connector 1, and the first sleeve 3 can also be connected to an external waterproof device to provide waterproof and dustproof protection for the plug terminal 2.
