Abstract

The present invention provides a floating connection structure and a connector. When in use, the insertion piece of the plug is inserted into the connector. If there is a deviation in the insertion position of the insertion piece in the connector (partly due to the influence of the insertion angle, and partly due to the deviation in the mating position caused by manufacturing and assembly precision), as the insertion piece is inserted, the insertion piece abuts against the contact terminal assembly. As the abutting force acts on the floating assembly, since the floating assembly is elastically connected to the connection assembly and a clearance fit is adopted between the floating assembly and the connection assembly, the abutting force during the insertion of the insertion piece will drive the floating assembly to move relative to the connection assembly, enabling the floating assembly to drive the contact terminal assembly to move relative to the connection assembly, ensuring that the insertion piece can be better inserted into the contact terminal assembly, keeping the insertion piece in a reasonable connection position all the time, and avoiding the difficulty of forming a stable electrical connection between the insertion piece and the contact terminal assembly due to the precision or deviation problem of the insertion piece.

Description

Technical Field

[0001] This application relates to the field of connectors, and particularly to a floating connection structure and a connector. Background Art

[0002] As a device used in cooperation with the inserts of a plug, due to its general-purpose characteristics, a connector is widely used in various power modules and supplies power to various electronic devices through different energy sources.

[0003] Existing power module boxes often adopt fixed connectors, that is, the internal structure of the connector is often fixed to prevent loosening or unstable connection of the internal structure of the connector.

[0004] However, due to the assembly accuracy and assembly tolerance of the inserts of plugs produced by different manufacturers, there will be a deviation in the assembly position directly, which will make it difficult for the inserts to be inserted into the connector when connected through a fixed connector. During the insertion process, problems such as jamming and failure will occur.

[0005] Some existing methods are to forcefully insert the insert into the connector. The insert will be deformed passively due to the force of forced insertion, so that the insert adapts to the connector. However, the insert inserted into the connector may not be able to make full contact with the terminals of the connector due to bending, resulting in unstable current transmission and affecting the normal operation of the device. Secondly, since the resistance of the bent part of the insert is extremely easy to increase after being bent, local heating problems will occur in the bent part, and the connector or plug may be burned out after long-term use.

[0006] Another method is to expose the terminals of the connector to the outside, so that the insert can make full contact with the terminals of the connector. However, the exposed terminals have no protection and are extremely prone to electrical safety problems and are not convenient to use.

[0007] Secondly, when the plug is inserted into the connector, it often does not insert 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 insert will directly abut against the terminals inside the connector. In order to ensure the stability of the connection, the terminals inside the connector are usually firmly connected to the housing of the connector. Under the influence of the insertion angle, the insert will directly abut against the terminals, resulting in deformation of the terminals due to the force. After long-term use, it is easy for the terminals to have poor contact with the inserted insert due to deformation. Poor contact is extremely likely to cause too large a change in current in a short time, and then cause damage to the 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 problem that it is difficult to achieve stable electrical connection with the connector due to the precision or tolerance problems of the insertion pieces of the plug.

Detailed implementation manners

[0078] The following will describe embodiments of the present application in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments.

[0079] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component. The terms "top", "bottom", "upper", "lower", "left", "right", "front", "rear", and similar expressions used herein are for illustrative purposes only.

[0080] The following will describe in detail some embodiments of the present application in conjunction with the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0081] An embodiment of the present application provides a floating connection structure 100, including:

[0082] A contact terminal assembly 110;

[0083] A floating assembly 120, one end of the contact terminal assembly 110 is fixed on the floating assembly 120;

[0084] A connection assembly 130, one end is elastically connected to the side of the floating assembly 120 away from the contact terminal assembly 110, the other end of the connection assembly 130 is electrically connected to an external circuit, and the floating assembly 120 and the connection assembly 130 are in clearance fit.

[0085] Please refer to Figures 1 to 2 , in this embodiment, when in use, insert the blade of the plug into the connector 150. If there is a deviation in the insertion position of the blade in the connector 150 (partly due to the influence of the insertion angle, and partly due to the influence of the blade angle caused by manufacturing precision), as the blade is inserted, the blade abuts against the contact terminal assembly 110.

[0086] As the abutting force acts on the floating assembly 120, since the floating assembly 120 and the connection assembly 130 are elastically connected, and the floating assembly 120 and the connection assembly 130 are connected in a clearance fit manner, the abutting force during the insertion of the blade will drive the floating assembly 120 to move relative to the connection assembly 130, so that the floating assembly 120 can drive the contact terminal assembly 110 to move relative to the connection assembly 130, and the blade can be better inserted into the contact terminal assembly 110, avoiding the problem that it is difficult for the blade to form a stable electrical connection with the contact terminal assembly due to the precision or deviation of the blade.

[0087] It should be noted that since the floating component 120 and the connecting component 130 are in clearance fit, when the insert is inserted into the contact terminal component 110 at an inclined angle, under the action of the abutting force, the contact terminal component 110 will apply the abutting force to the floating component 120. Under the action of the acting force, since the floating component 120 is elastically connected to the connecting component 130, the floating component 120 can move relative to the connecting component 130, thereby avoiding damage to the contact terminal component 110 caused by rigid contact of the insert, or difficulty in inserting the insert into the contact terminal component 110 due to rigid contact.

[0088] 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.

[0089] It should be further noted that the insert inserted into the contact terminal component 110 is electrically connected to an external circuit through the contact terminal component 110, the floating component 120, and the connecting component 130, thereby realizing power supply to an external device.

[0090] In at least one embodiment of the present application, the connecting component 130 includes:

[0091] A first connecting member 131, with a first receiving groove 131a opened on a side close to the floating component 120;

[0092] The floating component 120 includes:

[0093] A first elastic member 121, partially received in the first receiving groove 131a and the other part extending through the first receiving groove 131a to the outside. One end of the first elastic member 121 is electrically connected to the contact terminal component 110, and the other end is electrically connected to the first connecting member 131;

[0094] Wherein, when the insert is inserted obliquely, the inclined acting force acts on the contact terminal component 110, so that the contact terminal component 110 squeezes the first elastic member 121 to drive the contact terminal component 110 to generate 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.

[0095] In at least one embodiment of the present application, the first receiving groove 131a is an annular groove, and the first elastic member 121 is a metal elastic member.

[0096] It should be noted that the first elastic member 121 is a spring (or a spring piece or an elastic member, all of which can replace the spring and be placed in the first receiving groove 131a. In this embodiment, an annular spring is selected and installed in the first receiving groove 131a), and it is made of a conductive material. The first connecting member 131 is generally cylindrical, and the first receiving groove 131a is generally an annular groove.

[0097] Please refer to Figure 14 , the first elastic member 121 can be formed by connecting the heads and tails of a plurality of arc-shaped metal sheets with protrusions (arched in the middle) and depressions (depressed in the middle) to meet the requirements of deformation and electrical connection.

[0098] Please refer to Figure 15 , the first elastic member 121 can be composed of two nested rings, and the middle part is composed of a plurality of elastic pieces that arch to one side or both sides at intervals to meet the requirements of deformation and electrical connection.

[0099] Please refer to Figures 1 to 6 , in this embodiment, when the insertion piece is inserted obliquely into the floating connection structure 100, first, the insertion piece abuts against the contact terminal assembly 110. Since the insertion piece is inserted obliquely into the floating connection structure 100, the force exerted by the insertion piece on the contact terminal assembly 110 is inclined.

[0100] Under the action of the inclined force, since the contact terminal assembly 110 is fixedly connected to the floating assembly 120, the force generated by the contact terminal assembly 110 will act on the floating assembly 120 along the inclined 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 extends through the first receiving groove 131a to the outside, and the floating assembly 120 is in clearance fit with the first connecting member 131, the floating assembly 120 will compress the first elastic member 121 along the direction of the inclined force under the action of the inclined force, so that the first elastic member 121 is compressed, thereby causing the floating assembly 120 to deflect at an angle relative to the connection assembly 130 along the direction of the inclined force, so that a flexible contact is formed between the contact terminal assembly 110 and the insertion piece, rather than a rigid contact. This can avoid the situation of jamming and failure of the insertion piece during the process of inserting the floating connection structure 100 due to problems such as assembly accuracy, assembly deviation, and insertion angle of the insertion piece.

[0101] Make the process of inserting the insertion piece into the floating connection structure 100 smoother, and avoid affecting the smoothness and connection stability of the connection between the insertion piece and the floating connection structure 100 due to problems such as assembly accuracy, assembly deviation, and insertion angle of the insertion piece.

[0102] In at least one embodiment of the present application, a second receiving groove 131b is further formed on one side of the first connecting member 131 close to the floating assembly 120, and the first receiving groove 131a is disposed around the second receiving groove 131b;

[0103] The floating assembly 120 further includes:

[0104] A second elastic member 122 is disposed in the second receiving groove 131b, and the second elastic member 122 is in clearance fit with the second receiving groove 131b.

[0105] Please refer to Figures 1 to 6 , in this embodiment, when the insertion piece is obliquely inserted into the floating connection structure 100, first, the insertion piece abuts against the contact terminal assembly 110. Since the insertion piece is obliquely inserted into the floating connection structure 100, the acting force of the insertion piece on the contact terminal assembly 110 is inclined.

[0106] Under the action of the inclined acting force, the acting force of the insertion piece on the contact terminal assembly 110 acts on the first elastic member 121 and the second elastic member 122. The second elastic member 122 deforms. Under the elastic force of the second elastic member 122, the first elastic member 121 is prevented from being excessively squeezed to protect the first elastic member 121. At the same time, under the action of the second elastic member 122, a part of the acting force of the insertion piece on the floating assembly 120 acts on the second elastic member 122, and the other part acts on the first elastic member 121, so as to ensure the angle deflection effect of the floating assembly 120 driving the contact terminal assembly 110 relative to the connection assembly 130 under the inclined acting force, and avoid the problem of jamming of the insertion piece during insertion due to too small deflection angle.

[0107] Since the second elastic member 122 and the second receiving groove 131b are in clearance fit, when the inclined acting force of the insertion piece 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 inclined acting force and generate sufficient deformation to ensure the angle deflection range of the contact terminal assembly 110 relative to the connection assembly 130, and avoid problems such as deformation of the contact terminal assembly 110, jamming of the insertion piece, and poor contact caused by too small angle deflection range.

[0108] It should be noted that the second receiving groove 131b is a circular groove and is disposed at the geometric center position of the first receiving groove 131a.

[0109] The second elastic member 122 is made of an elastic deformation material, such as rubber, silica gel, etc. The outer shape of the second elastic member 122 is generally in the shape of an impeller.

[0110] 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;

[0111] The connecting portion 1221 is fixedly connected to the contact terminal assembly 110, there are multiple deformation portions 1222, and the multiple deformation portions 1222 are arranged at equal angles on the outer peripheral surface of the connecting portion 1221, and a deformation groove 122a is formed between two adjacent deformation portions 1222.

[0112] Please refer to Figures 1 to 6 , in this embodiment, when there are assembly accuracy and assembly deviation of the insertion piece, that is, the insertion piece is slightly larger or slightly smaller, resulting in a deviation in the position of the insertion piece. For a single insertion piece, when the insertion piece abuts against the contact terminal assembly 110, the contact terminal assembly 110 is provided with guiding inclined surfaces, and the two guiding inclined surfaces will guide the insertion piece to insert into the contact terminal assembly 110. When the insertion piece abuts against the guiding inclined surfaces of the contact terminal assembly 110, there is an inclined acting force on the guiding inclined surfaces, and the inclined acting force will directly act on the contact terminal assembly 110. A part of the inclined acting 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 inclined acting force, and the other part of the acting force acts on the second elastic member 122. The second elastic member 122 will displace in the second receiving groove 131b due to the action of the inclined acting force and deform in the direction of the inclined acting force, so that the deformation portion 1222 in the inclined direction is squeezed and deformed to adapt to the inclined acting force of the insertion piece, and finally the contact terminal assembly 110 deflects a certain angle relative to the connection assembly 130 in the inclined direction.

[0113] Even if the insertion pieces of the plug are affected by manufacturing accuracy and assembly accuracy, the floating connection structure 100 can still enable the insertion pieces to be inserted into the contact terminal assembly 110 of the floating connection structure 100 perfectly and smoothly to achieve electrical connection.

[0114] It should be noted that since a deformation groove 122a is formed between two adjacent deformation portions 1222, during the process of the second elastic member 122 being squeezed, the deformation groove 122a can increase the deformation degree between two adjacent deformation portions 1222, thereby improving the deformation effect, and further enabling the insertion pieces of the plug to still be inserted into the contact terminal assembly 110 in the case of deviation, and realizing electrical connection with an external power supply circuit through the floating assembly 120 and the connection assembly 130.

[0115] Since multiple deformation parts 1222 are arranged at an angle on the outer peripheral surface of the connecting part 1221, when the insertion piece presses and contacts the terminal assembly 110 at different angles, the second elastic pieces 122 of the floating assembly 120 can all deform at corresponding angles to conform to the insertion of the insertion piece into the terminal assembly 110, facilitating the use of the plug insertion piece.

[0116] It should be further noted that two or more floating connection structures 100 can be adopted in a single connector 150 to meet the insertion angles of each insertion piece of the plug and avoid the situation where the insertion piece cannot be inserted due to manufacturing precision problems of the insertion piece.

[0117] It should be further noted that the connecting part 1221 is generally cylindrical, and the deformation part 1222 is generally arc-shaped plate-like.

[0118] In at least one embodiment of the present application, the deformation part 1222 is bent along the second direction B, the second direction B is arranged along the circumferential direction of the connecting part 1221, and the bends of the multiple deformation parts 1222 are arranged in the same direction.

[0119] Please refer to Figures 1 to 6 , in this embodiment, since the deformation part 1222 is bent along the second direction B and the bends of the multiple deformation parts 1222 are arranged in the same direction, when the tilting force acts on the deformation part 1222, it can be bent along the bending direction of the deformation part 1222 to guide the extrusion direction of the deformation part 1222, so that the floating assembly 120 can generate an angular deflection in the vertical direction of the first direction A relative to the connection assembly 130, avoiding affecting the use due to the insertion angle of the insertion piece.

[0120] In at least one embodiment of the present application, a blocking surface 131c that inclines inward is formed by the protrusion of one inner wall on one side of the first receiving groove 131a, a guiding surface 131d is formed by the inward depression on the other side of the first receiving groove 131a, the guiding surface 131d and the blocking surface 131c have the same inclination angle, and the blocking surface 131c is arranged on the inner wall of the first receiving groove 131a on the side away from the second elastic piece 122.

[0121] Please refer to Figures 1 to 6, in the present embodiment, a blocking surface 131c that inclines inward is formed by protruding from a side of the first receiving groove 131a away from its center towards the center. 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 detaching from the first receiving groove 131a when the first elastic member 121 is subjected to an inclined acting force, so as to ensure the installation and positioning of the first elastic member 121, and avoid the extrusion direction of the inclined acting force being away from the center of the first receiving groove 131a (i.e., the center of the second receiving groove 131b), thereby causing the first elastic member 121 to detach from the first receiving groove 131a.

[0122] Since a guiding surface 131d is formed by inwardly recessing on the other side of the first receiving groove 131a, and the inclination angle of the guiding surface 131d is the same as that of the blocking surface 131c, the first elastic member 121 can be more easily installed into the first receiving groove 131a through the guiding surface 131d, and the installation of the first elastic member 121 is prevented from being blocked due to the presence of the blocking surface 131c.

[0123] It should be noted that both the blocking surface 131c and the guiding surface 131d are inclined surfaces, and both the blocking surface 131c and the guiding surface 131d are located on a side of the first receiving groove 131a close to the contact terminal assembly 110.

[0124] In at least one embodiment of the present application, the floating assembly 120 further includes:

[0125] A first conductive member 123, one end of which is fixedly connected to the contact terminal assembly 110, and the other end of which is 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.

[0126] Please refer to Figures 1 to 6 , in the present 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 abuts against the first elastic member 121 in an abutting manner, so as to ensure that the first elastic member 121 is always electrically connected to the first conductive member 123. The contact terminal assembly 110 forms an electrical connection with the first connection member 131 through the first conductive member 123 and the first elastic member 121 to ensure the smoothness of the circuit.

[0127] It should be noted that the first conductive member 123 is a circular metal disk with a through hole formed in the middle. The second elastic member 122 is fixed by passing a pin through the through hole, so that the second elastic member 122 is installed on a side of the first conductive member 123 away from the contact terminal assembly 110, so that the second elastic member 122 forms a fixed connection with the first conductive member 123.

[0128] It should be further noted that when the inclined or misaligned insert contacts the contact terminal assembly 110, the inclined acting force will be transmitted to the first conductive member 123. Under the action of the inclined acting force, a part of the inclined acting force acts on the first elastic member 121, causing the first conductive member 123 to squeeze the first elastic member 121. Under the squeezing acting force of the first conductive member 123, the first conductive member 123 and the first elastic member 121 always form an electrical connection.

[0129] Another part of the inclined acting force acts on the second elastic member 122. Since the second elastic member 122 is fixedly connected to the first conductive member 123 and has a clearance fit with the second receiving groove 131b, under the inclined acting force, the second elastic member 122 will be squeezed and deformed in the inclined direction, and at the same time, the second elastic member 122 will move in the inclined direction in the second receiving groove 131b to enable the entire floating assembly 120 to adapt to the inclination angle of the insert. This avoids damage to the contact terminal assembly 110 caused by rigid contact of the insert and difficulty in inserting the insert into the contact terminal assembly 110.

[0130] In at least one embodiment of the present application, the contact terminal assembly 110 includes:

[0131] A conductive terminal 111, one end of which is fixedly connected to the floating assembly 120 and the other end is provided with a conductive portion 1111;

[0132] A terminal clip 112, disposed on the side of the conductive terminal 111 away from the floating assembly 120 and in contact with the conductive terminal 111;

[0133] There are two sets of the contact terminal assemblies 110, the two sets of the contact terminal assemblies 110 are disposed opposite to each other, and a connection groove 111a is formed between the two conductive terminals 111 of the two sets of the contact terminal assemblies 110, and the two conductive terminals 111 of the two sets of the contact terminal assemblies 110 are located between the two terminal clips 112.

[0134] Please refer to Figures 1 to 6 , in this embodiment, in a single floating connection structure 100, there are two sets of the contact terminal assemblies 110, and the two sets of the contact terminal assemblies 110 are disposed opposite to each other. A connection groove 111a is formed between the two sets of the contact terminal assemblies 110, and the connection groove 111a is used to connect with the insert.

[0135] When the insert is inserted into the contact terminal assembly 110, the insert enters the connection groove 111a. Since the two terminal clips 112 are respectively in contact with the two conductive terminals 111, the two conductive terminals 111 will clamp the insert, so that a stable electrical connection is formed between the insert and the conductive terminals 111.

[0136] When the insert needs to be pulled out, pull out the insert, and the two terminal clips 112 are respectively abutted against the two conductive terminals 111, so that the two conductive terminals 111 return to their original state, avoiding the deformation of the conductive terminals 111 caused by the acting force of the insert on the conductive terminals 111, and further affecting the subsequent use.

[0137] It should be noted that the terminal clip 112 is made of an elastic material, one end is fixed to the side of the conductive terminal 111 close to the floating component 120, and the other end is inclined towards the other conductive terminal 111, so that the terminal clip 112 abuts against the conductive terminal 111 on the same side, thereby preventing the conductive terminal 111 from deforming during long-term use.

[0138] One end of the conductive terminal 111 is fixed to the first conductive member 123, and the other end is a conductive portion 1111. The conductive portion 1111 is a metal elastic sheet, and the conductive portion 1111 is inclined towards the other conductive terminal 111.

[0139] The terminal clip 112 is fixed to the first conductive member 123 by a pin.

[0140] In at least one embodiment of the present application, a third receiving groove 131e is provided on the side of the first connecting member 131 away from the floating component 120;

[0141] The connection assembly 130 further includes:

[0142] A third elastic member 132, partially received in the third receiving groove 131e and the other part extending to the outside;

[0143] The floating connection structure 100 further includes:

[0144] A second conductive member 140, located on the side of the first connecting member 131 away from the floating component 120 and in clearance fit 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.

[0145] Please refer to Figures 1 to 6 , in this embodiment, when the insert is inserted into the contact terminal assembly 110, the insert and the contact terminal assembly 110, the inclined abutting force acts on the floating component 120, and the floating component 120 is inclined relative to the connection assembly 130. Part of the inclined abutting force acts on the connection assembly 130. Since the third elastic member 132 is received in the third receiving groove 131e and the other part extends to the outside and abuts against the second conductive member 140, the first connecting member 131 can form a stable electrical connection with the second conductive member 140 through the third elastic member 132.

[0146] Enable the connecting component 130 to generate angular deflection relative to the second conductive member 140, thereby further increasing the smoothness of the insert insertion, enabling a larger floating angle of the floating connection structure 100, and facilitating the insertion and extraction of the insert. Secondly, by floatingly connecting the second conductive member 140 and the floating connection structure 100 with the third elastic member 132 and the fourth elastic member 133, when the side of the floating connection structure 100 close to the second conductive member 140 is connected to an external device, it can also perform floating adjustment to avoid the connection insert of the external device.

[0147] It should be further noted that when one end of the connector 150 close to the second conductive member 140 needs to be inserted into the housing of an external device, it is connected to the connection structure of the external housing through the third elastic member 132 and the fourth elastic member 133, further improving the flexibility of the connection with the external housing, that is, connecting to the outside through the first elastic member 121 and the second elastic member 122, the third elastic member 132 and the fourth elastic member 133, so that both ends of the connector 150 can be floatingly connected to the outside to improve the flexibility of the external connection of the connector 150.

[0148] 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 flexible copper bar or a wire. By floatingly connecting the second conductive member 140 and the connecting component 130, the floating angle of the floating connection structure 100 is further increased, thereby improving the applicability of the connector 150.

[0149] In at least one embodiment of the present application, a fourth receiving groove 131f is provided on the side of the first connecting member 131 away from the floating component 120;

[0150] The connecting component 130 further includes:

[0151] A fourth elastic member 133, one end of which is fixedly connected to the second conductive member 140, and the other end extends into the fourth receiving groove 131f and is in clearance fit with the fourth receiving groove 131f.

[0152] Please refer to Figures 1 to 6, in this embodiment, through the clearance fit between the third elastic member 132 and the fourth receiving groove 131f, a floating connection can be formed between the connection assembly 130 and the second conductive member 140. When an 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 combined action of the third elastic member 132 and the fourth elastic member 133, the second conductive member 140 can deflect at an angle in the vertical direction of the first direction A relative to the connection assembly 130. When one end of the connector 150 close to the second conductive member 140 needs to be inserted into the housing of an external device, it is connected through the connection structures of the third elastic member 132 and the fourth elastic member 133 with the external housing, further improving the flexibility of connection with the external housing, that is, connecting to the outside through the first elastic member 121 and the second elastic member 122, the third elastic member 132 and the fourth elastic member 133, so that both ends of the connector 150 can be floatingly connected to the outside to improve the flexibility of the external connection of the connector 150.

[0153] It should be noted that the fourth elastic member 133 and the second elastic member 122 have the same shape and the same installation method. The fourth receiving groove 131f and the second receiving groove 131b have the same shape.

[0154] An embodiment of the present application provides a connector 150, including the floating connection structure 100 described in any one of the above;

[0155] The connector 150 further includes:

[0156] A housing 151, which internally forms a receiving cavity 151a, a socket 151b, and a mounting opening 151c. The socket 151b and the mounting opening 151c are located on both sides of the housing 151, and both the socket 151b and the mounting opening 151c communicate with the receiving cavity 151a;

[0157] A terminal protection shell 152, which internally forms a mounting cavity 152a. The terminal protection shell 152 is disposed in the receiving cavity 151a, and the contact terminal assembly 110 is disposed in the mounting cavity 152a. The connection groove 111a communicates with the socket 151b through the mounting cavity 152a;

[0158] A floating assembly 120 is disposed in the receiving cavity 151a, and a part of the connection assembly 130 is disposed in the receiving cavity 151a, and the other part passes through the mounting opening 151c and extends to the outside and is electrically connected to an external circuit.

[0159] Please refer to Figures 1 to 13, in this embodiment, when there is a plug connection with assembly deviation, after the blade 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 blade of the plug into the socket 151b and then into the connection groove 111a, and abuts against the conductive terminal 111. The inclined acting force generated by the blade will directly act on the conductive terminal 111. Under the action of the inclined acting force, the conductive terminal 111 will act on the first conductive member 123. The inclined acting force on the first conductive member 123 will act on the first elastic member 121 and the second elastic member 122 in part. The first elastic member 121 and the second elastic member 122 will deform along the inclined direction, so that the entire floating assembly 120 deflects relative to the first connecting member 131 to adapt to the insertion angle of the blade.

[0160] The blade is electrically connected to the first connecting member 131 through the conductive terminal 111, the first conductive member 123, and the first elastic member 121, so as to be connected to the external circuit.

[0161] In another embodiment, when there is a plug connection with assembly deviation, the floating assembly 120 deflects relative to the first connecting member 131. The deflecting acting force will act on the connecting assembly 130 in part, on the third elastic member 132 in part, and on the fourth elastic member 133 in part. The acting force directions of the third elastic member 132 and the fourth elastic member 133 are inclined to generate deformation, so that the first connecting member 131 deflects relative to the second conductive member 140, thereby realizing further floating to adapt to the insertion angle of the blade. Even if the assembly deviation of the blade is large, through the floating structure in this embodiment, an electrical connection can be formed, and the blade with a large assembly deviation can be inserted into the connection groove 111a to form a stable electrical connection to ensure the safety of power use.

[0162] It should be noted that the housing 151 is generally a rectangular housing 151. The accommodating cavity 151a is a through cavity. The socket 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 blade. The installation opening 151c is an opening on the other side of the accommodating cavity 151a for leading out the second conductive member 140 and forming an electrical connection with the outside.

[0163] In at least one embodiment of the present application, a first limiting groove 151d is provided in the housing 151;

[0164] The connector 150 further includes:

[0165] A first sealing member 153, disposed between the limiting member 154 and the first connecting member 131;

[0166] The limiting member 154 is disposed within the accommodating cavity 151a. The limiting member 154 is provided with a connecting cavity. One end of the connecting component 130 penetrates through the connecting cavity and extends outside the housing 151. A second limiting groove 154a is formed on the outer peripheral surface of the limiting member 154;

[0167] The second sealing member 155 is disposed between the limiting member 154 and the housing 151;

[0168] One end of the fixing member 156 is received within the first limiting groove 151d, and the other end penetrates through the first limiting groove 151d and extends into the second limiting groove 154a;

[0169] Sealant (not shown in the figure) is filled within the accommodating cavity 151a. Please refer to Figures 1 to 13 , in the present embodiment, the first sealing member 153 is used to seal the connection between the limiting member 154 and the first connecting member 131, thereby preventing a gap between the limiting member 154 and the first connecting member 131 and affecting its waterproof performance; the second sealing member 155 is used to seal the connection between the limiting member 154 and the housing 151, thereby preventing a gap between the limiting member 154 and the housing 151 and affecting its waterproof performance; the limiting member 154 is fixed within the accommodating cavity 151a by the fixing member 156 to prevent 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).

[0170] The sealant is filled within the accommodating cavity 151a in a potting sealing manner to ensure the waterproof performance of the entire connector 150.

[0171] It should be noted that both the first sealing member 153 and the second sealing member 155 are sealing rings. The limiting member 154 is generally in the shape of a rectangular block. The connecting cavity is for the penetration of the second conductive member 140, so that the second conductive member 140 can extend to the outside and be electrically connected to an external circuit. The terminal protection housing 152 is generally in the shape of a rectangular frame and is used to protect the conductive terminal 111.

[0172] It should be further noted that in one embodiment, the first sealing member 153 and the second sealing member 155 are used to seal the internal structure of the connector 150, thereby improving the sealing performance. In another embodiment, sealant is used to seal the internal structure of the connector 150 to improve the overall sealing performance. In other embodiments, the first sealing member 153, the second sealing member 155, and the sealant can be used in combination for sealing.

[0173] It should be further noted 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.

[0174] The fixing member 156 is a pin.

[0175] The above are only the embodiments of the present application. It should be noted here that for those of ordinary skill in the art, improvements can be made without departing from the inventive concept of the present application, but these all fall within the protection scope of the present application.
