Floating connection structure and connector

Abstract

The invention provides a floating connection structure and a connector, when the floating connection structure is used, a plug piece of a plug is inserted into the connector, and if the plug piece has deviation in the insertion position of the connector (one part is influenced by the insertion angle, and the other part is possibly the deviation of the insertion position caused by the manufacturing and assembling precision), the plug piece can be inserted into the connector along with the insertion of the plug piece. The insertion piece abuts against the contact terminal assembly. As the abutting action force acts on the floating assembly, the floating assembly is elastically connected with the connecting assembly, and the floating assembly and the connecting assembly are in clearance fit, so that the abutting force generated when the inserting piece is inserted can drive the floating assembly to move relative to the connecting assembly; therefore, the floating assembly can drive the contact terminal assembly to move relative to the connecting assembly, it is guaranteed that the insertion piece can be better inserted into the contact terminal assembly, the insertion piece is located at the reasonable connecting position all the time, and it is avoided that due to the precision or deviation problem of the insertion piece, the insertion piece and the contact terminal assembly are difficult to form stable electric connection.

Description

Technical Field

[0001] The present application relates to the field of connectors, and in particular to a floating connection structure and a connector. Background Art

[0002] As a device used in conjunction with the plug blades, the connector is widely used in various power modules due to its versatility, and supplies energy to various electronic devices through different energy sources.

[0003] Existing power module boxes often use fixed connectors, that is, the structure inside the connector is often fixed to avoid looseness of the structure inside the connector or unstable connection.

[0004] However, due to the assembly precision and tolerance of the plugs produced by different manufacturers, the assembly position of the plugs will be directly deviated, which will make it difficult to insert the plugs into the connector when connecting through a fixed connector, causing problems such as jamming and failure during the insertion process.

[0005] Some existing practices are to forcibly insert the plug into the connector. The plug will be passively deformed due to the force of forced insertion, so that the plug fits the connector. However, due to the bending of the plug inserted into the connector, it may not be able to fully contact the connector terminal, resulting in unstable current transmission and affecting the normal operation of the equipment. Secondly, since the plug is easily bent, the resistance of the bent part will increase, causing local heating in the bent part, and long-term use may burn the connector or plug.

[0006] Another approach is to expose the connector terminals to the outside so that the plug can fully contact the connector terminals. However, the exposed terminals have no protection, which can easily cause electrical safety problems and are inconvenient to use.

[0007] Secondly, when the plug is inserted into the connector, it is often not inserted vertically into the connector, and there will be a slight deviation in the insertion angle between the plug and the connector. At this time, the plug will directly contact the terminal inside the connector, and the terminal inside the connector is usually firmly connected to the connector shell for the stability of the connection. Under the influence of the insertion angle, the plug will directly contact the terminal, causing the terminal to be deformed due to force. After long-term use, it is easy for the terminal to have poor contact with the inserted plug due to deformation. Poor contact can easily cause excessive current changes in a short period of time, which in turn causes damage to electrical equipment. Summary of the invention

[0008] In view of this, it is necessary to provide a floating connection structure and a connector to solve the above-mentioned problem that it is difficult to achieve a stable electrical connection with the connector due to accuracy or tolerance issues of the plug blades.

[0025] The embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0026] It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a central component at the same time. When a component is considered to be "located on" another component, it may be directly located on the other component or there may be a central component at the same time. The terms "top", "bottom", "upper", "lower", "left", "right", "front", "back", and similar expressions used herein are for illustrative purposes only.

[0027] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0028] An embodiment of the present application provides a floating connection structure 100, comprising: Contact terminal assembly 110; A floating assembly 120, on which one end of the contact terminal assembly 110 is fixed; One end of the connecting component 130 is elastically connected to a side of the floating component 120 away from the contact terminal component 110 , and the other end of the connecting component 130 is electrically connected to an external circuit. The floating component 120 and the connecting component 130 are clearance-matched. Please refer to Figure 1 to Figure 2In this embodiment, when in use, the plug of the plug is inserted into the connector 150. If there is a deviation in the insertion position of the plug in the connector 150 (partly due to the influence of the insertion angle, and partly due to the manufacturing accuracy causing the angle of the plug), as the plug is inserted, the plug abuts against the contact terminal assembly 110.

[0029] As the abutting force acts on the floating component 120, since the floating component 120 and the connecting component 130 are elastically connected and the floating component 120 and the connecting component 130 are connected in a clearance fit manner, the abutting force of the inserted plug will drive the floating component 120 to move relative to the connecting component 130, so that the floating component 120 can drive the contact terminal component 110 to move relative to the connecting component 130, and the plug can be better inserted into the contact terminal component 110, avoiding the difficulty of the plug in forming a stable electrical connection with the contact terminal assembly due to the accuracy or deviation of the plug.

[0030] It should be noted that due to the clearance fit between the floating component 120 and the connecting component 130, when the plug is inserted into the contact terminal component 110 at an inclined angle, under the action of the resisting force, the contact terminal component 110 will apply the resisting force to the floating component 120. Under the action of the force, the floating component 120 is elastically connected to the connecting component 130, so that the floating component 120 can move relative to the connecting component 130, thereby avoiding damage to the contact terminal component 110 due to rigid contact of the plug, or difficulty in inserting the plug into the contact terminal component 110 due to rigid contact.

[0031] Secondly, since the floating component 120 moves relative to the connecting component 130 , even if the insert has precision or assembly problems during manufacturing, it can still be easily inserted into the contact terminal component 110 under the action of the floating component 120 to form an electrical connection.

[0032] It should be further explained that the plug inserted into the contact terminal assembly 110 is electrically connected to the external circuit through the contact terminal assembly 110, the floating assembly 120 and the connecting assembly 130, so as to provide power to the external device.

[0033] In at least one embodiment of the present application, the connection component 130 includes: The first connecting member 131 has a first receiving groove 131a formed on one side close to the floating assembly 120; The floating assembly 120 includes: A first elastic member 121, part of which is received in the first receiving groove 131a, and the other part of which passes through the first receiving groove 131a and extends to the outside, wherein one end of the first elastic member 121 is electrically connected to the contact terminal assembly 110, and the other end is electrically connected to the first connecting member 131; When the plug is inserted at an angle, an inclined force acts on the contact terminal assembly 110, so that the contact terminal assembly 110 squeezes the first elastic member 121, thereby driving the contact terminal assembly 110 to produce an angular deflection in a first direction A relative to the first connecting member 131, and the first direction A is perpendicular to the opening direction of the first receiving groove 131a.

[0034] In at least one embodiment of the present application, the first receiving groove 131 a is an annular groove, and the first elastic member 121 is a metal elastic member.

[0035] It should be noted that the first elastic member 121 is a spring (or a spring sheet or an elastic member, which can replace the spring and be placed in the first receiving groove 131a. In this embodiment, an annular spring is selected to be installed in the first receiving groove 131a), and is made of conductive material. The first connecting member 131 is roughly cylindrical, and the first receiving groove 131a is roughly a circular groove.

[0036] Please refer to Fig.14 The first elastic member 121 can be formed by connecting a plurality of arc-shaped metal sheets with protrusions (arched in the middle) and depressions (depressed in the middle) end to end to meet the requirements of deformation and electrical connection.

[0037] Please refer to Fig.15 The first elastic member 121 may be composed of two sleeved rings, and a plurality of spring sheets arched to one side or both sides are arranged at intervals in the middle to meet the requirements of deformation and electrical connection.

[0038] Please refer to Figures 1 to 6 In this embodiment, when the plug is obliquely inserted into the floating connection structure 100, the plug first abuts against the contact terminal assembly 110. Since the plug is obliquely inserted into the floating connection structure 100, the force exerted by the plug on the contact terminal assembly 110 is inclined.

[0039] Under the action of the tilting force, since the contact terminal assembly 110 is fixedly connected to the floating assembly 120, the action force generated by the contact terminal assembly 110 will act on the floating assembly 120 along the tilting direction. Since a part of the first elastic member 121 of the floating assembly 120 is received in the first receiving groove 131a, and the other part passes through the first receiving groove 131a and extends to the outside, and the floating assembly 120 and the first connecting member 131 are in clearance fit, the floating assembly 120 will press the first elastic member 121 along the direction of the tilting force under the action of the tilting force, so that the first elastic member 121 is compressed, so that the floating assembly 120 is angularly deflected relative to the connecting assembly 130 along the direction of the tilting force, so that the contact terminal assembly 110 and the plug are in flexible contact instead of rigid contact. This is to avoid the plug being stuck or failing during the insertion of the floating connection structure 100 due to problems with assembly accuracy, assembly deviation, and insertion angle.

[0040] This makes the insertion of the plug into the floating connection structure 100 smoother, and avoids problems with plug assembly accuracy, assembly deviation, and insertion angle that may affect the smoothness and stability of the connection between the plug and the floating connection structure 100.

[0041] In at least one embodiment of the present application, a second receiving groove 131b is further provided on a side of the first connecting member 131 close to the floating assembly 120, and the first receiving groove 131a is arranged around the second receiving groove 131b; The floating assembly 120 further includes: The second elastic member 122 is disposed in the second receiving groove 131 b , and the second elastic member 122 and the second receiving groove 131 b are clearance-matched.

[0042] Please refer to Figures 1 to 6 In this embodiment, when the plug is obliquely inserted into the floating connection structure 100, the plug first abuts against the contact terminal assembly 110. Since the plug is obliquely inserted into the floating connection structure 100, the force exerted by the plug on the contact terminal assembly 110 is inclined.

[0043] Under the action of the tilting force, the force of the plug on the contact terminal assembly 110 acts on the first elastic member 121 and the second elastic member 122, and the second elastic member 122 is deformed. Under the elastic force of the second elastic member 122, the first elastic member 121 is prevented from being over-squeezed to protect the first elastic member 121. At the same time, under the action of the second elastic member 122, part of the force of the plug on the floating assembly 120 acts on the second elastic member 122, and the other part acts on the first elastic member 121, thereby ensuring that under the tilting force, the floating assembly 120 drives the contact terminal assembly 110 to deflect relative to the connecting assembly 130, thereby avoiding the problem of the plug getting stuck during the insertion process due to the deflection angle being too small.

[0044] Since the second elastic member 122 and the second receiving groove 131b are clearance-fitted, when the tilting force of the plug acts on the second elastic member 122, the second elastic member 122 can move in the second receiving groove 131b along the direction of the tilting force and produce sufficient deformation to ensure the angular deflection range of the contact terminal assembly 110 relative to the connecting assembly 130, thereby avoiding deformation of the contact terminal assembly 110, jamming of the plug, and poor contact due to too small an angular deflection range.

[0045] It should be noted that the second receiving groove 131 b is a circular groove and is disposed at the geometric center of the first receiving groove 131 a.

[0046] The second elastic member 122 is made of an elastic deformable material, such as rubber, silicone, etc. The shape of the second elastic member 122 is substantially in the shape of an impeller.

[0047] In at least one embodiment of the present application, the second elastic member 122 includes a connecting portion 1221 and a deformation portion 1222 fixedly connected to the connecting portion 1221; The connecting portion 1221 is fixedly connected to the contact terminal assembly 110 . There are multiple deformable portions 1222 . The multiple deformable portions 1222 are arranged at equal angles on the outer peripheral surface of the connecting portion 1221 . A deformation groove 122 a is formed between two adjacent deformable portions 1222 .

[0048] Please refer to Figures 1 to 6In this embodiment, when there is assembly accuracy and assembly deviation in the plug, that is, the plug is slightly larger or smaller, resulting in a deviation in the position of the plug, for a single plug, when the plug abuts against the contact terminal assembly 110, a guiding slope is provided on the contact terminal assembly 110, and the two guiding slopes will guide the plug to be inserted into the contact terminal assembly 110. When the plug abuts against the guiding slopes of the contact terminal assembly 110, there is an inclined force on the guiding slopes, and the inclined force will directly act on the contact terminal assembly 110. Part of the tilting force acting on the contact terminal assembly 110 acts on the first elastic member 121, so that a part of the first elastic member 121 is compressed along the direction of the tilting force, and the other part of the force acts on the second elastic member 122. The second elastic member 122 will be displaced in the second receiving groove 131b due to the action of the tilting force, and will be deformed in the direction of the tilting force, so that the deformation part 1222 in the tilting direction is squeezed and deformed to adapt to the tilting force of the plug, and finally the contact terminal assembly 110 is deflected by a certain angle in the tilting direction relative to the connecting assembly 130.

[0049] Even if the plug blades of the plug are affected by the manufacturing accuracy and the assembly accuracy, the floating connection structure 100 can still enable the plug blades to be intactly and smoothly inserted into the contact terminal assembly 110 of the floating connection structure 100 to achieve electrical connection.

[0050] It should be noted that since a deformation groove 122a is formed between two adjacent deformation parts 1222, when the second elastic member 122 is squeezed, the deformation groove 122a can increase the degree of deformation between the two adjacent deformation parts 1222, thereby improving the deformation effect, so that the plug of the plug can still be inserted into the contact terminal assembly 110 in the presence of deviation, and electrically connected to the external power supply circuit through the floating assembly 120 and the connecting assembly 130.

[0051] Since multiple deformation parts 1222 are arranged at equal angles on the outer peripheral surface of the connecting part 1221, when the plug is pressed against the contact terminal assembly 110 at different angles, the second elastic member 122 of the floating assembly 120 can be deformed at corresponding angles to accommodate the insertion of the plug into the contact terminal assembly 110, thereby facilitating the use of the plug.

[0052] It should be further explained that two or more floating connection structures 100 can be used in a single connector 150 to meet the insertion angle of each plug of the plug and avoid the situation where the plug cannot be inserted due to problems with manufacturing accuracy.

[0053] It should be further explained that the connecting portion 1221 is substantially cylindrical, and the deforming portion 1222 is substantially arc-shaped.

[0054] In at least one embodiment of the present application, the deformation portion 1222 is bent along a second direction B, the second direction B is arranged along the circumference of the connecting portion 1221, and the bends of the plurality of deformation portions 1222 are arranged along the same direction.

[0055] Please refer to Figures 1 to 6 In the present embodiment, since the deformation portion 1222 is bent along the second direction B, and the bending of the plurality of deformation portions 1222 is arranged along the same direction, when the tilting force acts on the deformation portion 1222, the deformation portion 1222 can be bent along the bending direction to guide the extrusion direction of the deformation portion 1222, so that the floating component 120 can generate an angle deflection relative to the connecting component 130 in the vertical direction on the first direction A to avoid affecting the use due to the insertion angle of the plug.

[0056] In at least one embodiment of the present application, an inner wall on one side of the first receiving groove 131a protrudes to form an inwardly inclined blocking surface 131c, and the other side of the first receiving groove 131a is recessed inward to form a guiding surface 131d, and the guiding surface 131d has the same inclination angle as the blocking surface 131c, and the blocking surface 131c is arranged on the inner wall of the first receiving groove 131a away from the second elastic member 122.

[0057] Please refer to Figures 1 to 6 In the present embodiment, one side of the first receiving groove 131a away from the center thereof protrudes toward the center thereof to form an inwardly inclined blocking surface 131c. When the first elastic member 121 is installed in the first receiving groove 131a, the blocking surface 131c can prevent the first elastic member 121 from being disengaged from the first receiving groove 131a when the first elastic member 121 is subjected to an inclined force, so as to ensure the installation positioning of the first elastic member 121 and prevent the first elastic member 121 from being disengaged from the first receiving groove 131a due to the extrusion direction of the inclined force being away from the center of the first receiving groove 131a (i.e., the center of the second receiving groove 131b).

[0058] Since the other side of the first receiving groove 131a is recessed inward to form a guide surface 131d, and the guide surface 131d and the blocking surface 131c have the same inclination angle, the first elastic member 121 can be more easily installed into the first receiving groove 131a through the guide surface 131d, thereby avoiding the blocking surface 131c from blocking the installation of the first elastic member 121.

[0059] It should be noted that both the blocking surface 131 c and the guiding surface 131 d are inclined surfaces, and both the blocking surface 131 c and the guiding surface 131 d are located on a side of the first receiving groove 131 a close to the contact terminal assembly 110 .

[0060] In at least one embodiment of the present application, the floating assembly 120 further includes: The first conductive member 123 has one end fixedly connected to the contact terminal assembly 110 and the other end fixedly connected to the second elastic member 122 . The first elastic member 121 abuts against the first conductive member 123 , and the first elastic member 121 is electrically connected to the first conductive member 123 .

[0061] Please refer to Figures 1 to 6 In this embodiment, one end of the first conductive member 123 is fixedly connected to the contact terminal assembly 110 by a pin, and the other end is abutted against the first elastic member 121 by abutment, thereby ensuring that the first elastic member 121 is always electrically connected to the first conductive member 123. The contact terminal assembly 110 is electrically connected to the first connecting member 131 through the first conductive member 123, the first elastic member 121, to ensure the smoothness of the circuit.

[0062] It should be noted that the first conductive member 123 is a ring-shaped metal disk with a through hole in the middle. The second elastic member 122 is fixed by a pin passing through the through hole, so that the second elastic member 122 is installed on the side of the first conductive member 123 away from the contact terminal assembly 110, so that the second elastic member 122 and the first conductive member 123 form a fixed connection.

[0063] It should be further explained that when a tilted or assembly-deviant plug abuts against the contact terminal assembly 110, the tilting force will be transmitted to the first conductive member 123. When the first conductive member 123 is acted upon by the tilting force, a part of the tilting force acts on the first elastic member 121, so that the first conductive member 123 squeezes the first elastic member 121. Under the squeezing force of the first conductive member 123, the first conductive member 123 and the first elastic member 121 are always electrically connected.

[0064] Another part of the tilting force acts on the second elastic member 122. Since the second elastic member 122 is fixedly connected to the first conductive member 123, the second elastic member 122 and the second receiving groove 131b are clearance-matched. Under the tilting force, the second elastic member 122 will be squeezed and deformed in the tilting direction. At the same time, the second elastic member 122 will move in the tilting direction in the second receiving groove 131b, so that the entire floating assembly 120 adapts to the tilting angle of the plug-in. This avoids damage to the contact terminal assembly 110 due to the rigid contact of the plug-in, and prevents the plug-in from being difficult to insert into the contact terminal assembly 110.

[0065] In at least one embodiment of the present application, the contact terminal assembly 110 includes: A conductive terminal 111, one end of which is fixedly connected to the floating assembly 120, and the other end of which is provided with a conductive portion 1111; The terminal clip 112 is disposed on a side of the conductive terminal 111 away from the floating assembly 120 and abuts against the conductive terminal 111; The contact terminal assemblies 110 are in two groups, which are arranged opposite to each other, and a connecting groove 111a is formed between the two conductive terminals 111 of the two groups of contact terminal assemblies 110, and the two conductive terminals 111 of the two groups of contact terminal assemblies 110 are located between the two terminal clips 112.

[0066] Please refer to Figures 1 to 6 In this embodiment, in a single floating connection structure 100, there are two groups of contact terminal assemblies 110, and the two groups of contact terminal assemblies 110 are arranged opposite to each other, and a connecting groove 111a is formed between the two groups of contact terminal assemblies 110, and the connecting groove 111a is used to connect with the plug.

[0067] When the plug is inserted into the contact terminal assembly 110 , the plug enters the connection slot 111 a . Since the two terminal clamps 112 are respectively in contact with the two conductive terminals 111 , the two conductive terminals 111 clamp the plug, forming a stable electrical connection between the plug and the conductive terminals 111 .

[0068] When the plug needs to be pulled out, the plug is pulled out, and the two terminal clips 112 respectively abut against the two conductive terminals 111, so that the two conductive terminals 111 return to their original state, avoiding deformation of the conductive terminals 111 due to the force of the plug on the conductive terminals 111, thereby affecting subsequent use.

[0069] It should be noted that the terminal clip 112 is made of elastic material, one end of which is fixed to the side of the conductive terminal 111 close to the floating component 120, and the other end is inclined toward the conductive terminal 111 on the other side, so that the terminal clip 112 abuts against the conductive terminal 111 on the same side, thereby preventing the conductive terminal 111 from being deformed during long-term use.

[0070] One end of the conductive terminal 111 is fixed on the first conductive member 123 , and the other end is a conductive portion 1111 . The conductive portion 1111 is a metal spring. The conductive portion 1111 is tilted toward another conductive terminal 111 .

[0071] The terminal clip 112 is fixed to the first conductive member 123 by means of pins.

[0072] In at least one embodiment of the present application, a third receiving groove 131e is formed on a side of the first connecting member 131 away from the floating assembly 120; The connection component 130 further includes: The third elastic member 132 is partially received in the third receiving groove 131e, and the other part extends to the outside; The floating connection structure 100 further includes: The second conductive member 140 is located on a side of the first connecting member 131 away from the floating assembly 120 and is loosely fitted with the first connecting member 131 . One end of the third elastic member 132 is electrically connected to the first connecting member 131 , and the other end is electrically connected to the second conductive member 140 . The second conductive member 140 abuts against the third elastic member 132 .

[0073] Please refer to Figures 1 to 6 In this embodiment, when the plug is inserted into the contact terminal assembly 110, the plug and the contact terminal assembly 110, the inclined abutment force acts on the floating assembly 120, the floating assembly 120 is inclined relative to the connecting assembly 130, and part of the inclined abutment force acts on the connecting assembly 130. Since the third elastic member 132 is received in the third receiving groove 131e, the other part extends to the outside and abuts against the second conductive member 140, so that the first connecting member 131 can form a stable electrical connection with the second conductive member 140 through the third elastic member 132.

[0074] The connection assembly 130 can be deflected at an angle relative to the second conductive member 140, thereby further increasing the smoothness of the plug insertion, making the floating angle of the floating connection structure 100 larger, and facilitating the insertion and removal of the plug. Secondly, the second conductive member 140 and the floating connection structure 100 are connected in a floating manner using the third elastic member 132 and the fourth elastic member 133, so that the side of the floating connection structure 100 close to the second conductive member 140 can also be adjusted in a floating manner when connected to an external device, thereby avoiding the connection plug of the external device.

[0075] It should be further explained that when the end of the connector 150 close to the second conductive member 140 needs to be inserted into the box of an external device, it is connected to the connecting structure of the external box through the third elastic member 132 and the fourth elastic member 133, so as to further improve the flexibility of the connection with the external box, that is, the first elastic member 121 and the second elastic member 122, the third elastic member 132 and the fourth elastic member 133 are connected to the outside, so that both ends of the connector 150 can be floatingly connected to the outside, so as to improve the flexibility of the connector 150 in external connection.

[0076] It should be noted that the third receiving groove 131e has the same shape as the first receiving groove 131a, and the third elastic member 132 is the same as the first elastic member 121. The second conductive member 140 is a soft copper bar or a wire, and is floatingly connected to the connecting assembly 130 through the second conductive member 140, further increasing the floating angle of the floating connection structure 100, thereby improving the applicability of the connector 150.

[0077] In at least one embodiment of the present application, a fourth receiving groove 131f is formed on a side of the first connecting member 131 away from the floating assembly 120; The connection component 130 further includes: One end of the fourth elastic member 133 is fixedly connected to the second conductive member 140 , and the other end extends into the fourth receiving groove 131 f and is gap-fitted with the fourth receiving groove 131 f .

[0078] Please refer to Figures 1 to 6 In this embodiment, the third elastic member 132 and the fourth receiving groove 131f are clearance-matched, so that a floating connection can be formed between the connecting component 130 and the second conductive member 140. When the inclined abutting force acts on the second conductive member 140, a part of the force will directly act on the third elastic member 132, and the other part will directly act on the fourth elastic member 133. Under the joint action of the third elastic member 132 and the fourth elastic member 133, the second conductive member 140 can be angularly deflected relative to the connecting component 130 in the vertical direction of the first direction A. When the end of the connector 150 close to the second conductive member 140 needs to be inserted into the box of an external device, the third elastic member 132 and the fourth elastic member 133 are connected to the external box through the connection structure, so as to further improve the flexibility of the connection with the external box, that is, the first elastic member 121 and the second elastic member 122, the third elastic member 132 and the fourth elastic member 133 are connected to the outside, so that both ends of the connector 150 can be externally floatingly connected, so as to improve the flexibility of the connector 150 in external connection.

[0079] It should be noted that the fourth elastic member 133 has the same shape and the same installation method as the second elastic member 122. The fourth receiving groove 131f has the same shape as the second receiving groove 131b.

[0080] An embodiment of the present application provides a connector 150 , comprising the floating connection structure 100 as described in any one of the above; The connector 150 further includes: The housing 151 has a receiving cavity 151a, a socket 151b and a mounting opening 151c formed therein. The socket 151b and the mounting opening 151c are located on both sides of the housing 151. Both the socket 151b and the mounting opening 151c are communicated with the receiving cavity 151a. The terminal protection shell 152 has an installation cavity 152a formed therein. The terminal protection shell 152 is disposed in the accommodating cavity 151a. The contact terminal assembly 110 is disposed in the installation cavity 152a. The connection groove 111a is connected to the socket 151b through the installation cavity 152a. The floating component 120 is disposed in the accommodating cavity 151 a , and a portion of the connecting component 130 is disposed in the accommodating cavity 151 a , and another portion thereof passes through the mounting opening 151 c and extends to the outside and is electrically connected to an external circuit.

[0081] Please refer to Figures 1 to 13 In this embodiment, when a plug connection with an assembly deviation exists, after the plug of the plug is inserted into the socket 151b, it first abuts against the terminal protection shell 152. The terminal protection shell 152 guides the plug of the plug into the socket 151b and then into the connecting groove 111a, and abuts against the conductive terminal 111. The tilting force generated by the plug will directly act on the conductive terminal 111. The conductive terminal 111 will act on the first conductive member 123 under the action of the tilting force. A part of the tilting force on the first conductive member 123 will act on the first elastic member 121, and the other part will act on the second elastic member 122. The first elastic member 121 and the second elastic member 122 will deform along the tilting direction, so that the entire floating assembly 120 will be deflected relative to the first connecting member 131 to adapt to the insertion angle of the plug.

[0082] The plug is electrically connected to the first connecting member 131 through the conductive terminal 111 , the first conductive member 123 , the first elastic member 121 , and thus communicated with an external circuit.

[0083] In another embodiment, when there is a plug connection with an assembly deviation, the floating component 120 is deflected relative to the first connecting member 131, and the deflection force will partially act on the connecting component 130, partially act on the third elastic member 132, and another part on the fourth elastic member 133. The directions of the forces of the third elastic member 132 and the fourth elastic member 133 are tilted and deformed, so that the first connecting member 131 is deflected relative to the second conductive member 140, thereby achieving further floating to adapt to the angle of insertion of the plug. Even if the assembly deviation of the plug is large, an electrical connection can be formed through the floating structure in this embodiment, and a plug with a large assembly deviation can be inserted into the connecting groove 111a to form a stable electrical connection to ensure the safety of electricity use.

[0084] It should be noted that the housing 151 is a substantially rectangular housing 151, the accommodating cavity 151a is a through cavity, the plug port 151b is an opening on one side of the accommodating cavity 151a, and is provided with an inclined surface for guiding the insertion of the plug. The installation port 151c is an opening on the other side of the accommodating cavity 151a, and is used to lead out the second conductive member 140 and form an electrical connection with the outside.

[0085] In at least one embodiment of the present application, a first limiting groove 151d is provided in the housing 151; The connector 150 further includes: A first sealing member 153 is disposed between the limiting member 154 and the first connecting member 131; The limiting member 154 is disposed in the accommodating cavity 151a. The limiting member 154 defines a connecting cavity. One end of the connecting assembly 130 passes through the connecting cavity and extends to the outside of the housing 151. The outer peripheral surface of the limiting member 154 defines a second limiting groove 154a. A second sealing member 155 is disposed between the limiting member 154 and the housing 151; A fixing member 156, one end of which is received in the first limiting groove 151d, and the other end of which passes through the first limiting groove 151d and extends into the second limiting groove 154a; Sealant (not shown) is filled in the accommodating cavity 151a. Figures 1 to 13 In this embodiment, the first sealing member 153 is used to seal the connection between the limiting member 154 and the first connecting member 131, so as to avoid the presence of a gap between the limiting member 154 and the first connecting member 131 and affect its waterproof performance; the second sealing member 155 is used to seal the connection between the limiting member 154 and the shell 151, so as to avoid the presence of a gap between the limiting member 154 and the shell 151 and affect its waterproof performance; the limiting member 154 is fixed in the accommodating cavity 151a by the fixing member 156 to avoid displacement of the limiting member 154, thereby ensuring the stability of the connecting component 130 (in this embodiment, the connecting component 130 does not adopt a floating design).

[0086] The sealant is filled into the accommodating cavity 151 a by a sealing method to ensure the waterproof performance of the entire connector 150 .

[0087] It should be noted that the first sealing member 153 and the second sealing member 155 are both sealing rings, the stopper 154 is roughly rectangular, and the connecting cavity is used for the second conductive member 140 to penetrate, so that the second conductive member 140 can extend to the outside and be electrically connected to the external circuit. The terminal protection shell 152 is roughly a rectangular frame, which is used to protect the conductive terminal 111.

[0088] It should be further explained that, in one embodiment, the first seal 153 and the second seal 155 are used to seal the internal structure of the connector 150, so as to improve the sealing performance. In another embodiment, a sealant is used to seal the internal structure of the connector 150 to improve the overall sealing performance. In other embodiments, the first seal 153, the second seal 155 and the sealant can be used in combination with each other for sealing.

[0089] It should be further explained that during the sealing process, it is necessary to avoid sealing the floating structure part to ensure the floating effect of the floating connection structure.

[0090] The fixing member 156 is a pin.

[0091] The above is only an implementation method of the present application. It should be pointed out that a person skilled in the art can make improvements without departing from the inventive concept of the present application, but these improvements are within the scope of protection of the present application.
