Examples

See fig. 1-13.

The present embodiment provides a connector commonly referred to as a male connector.

The connector of the present embodiment includes an insulation base (not shown) for a user to hold the connector for plugging operation, and one or more first conductor bases 11 are disposed on the insulation base, wherein the directions of the first conductor bases 11 may be the same direction, or may be opposite directions, or may be partially a front-rear direction, and partially a left-right direction. And are not limited herein.

Referring to fig. 1 to 14, the first conductor mount 11 provided with the first conductor insert 21 provided in the present embodiment will be hereinafter referred to as a first conductor mount 11.

At least one end portion of the first conductor base 11 is provided with a conductor insert (denoted as a first conductor insert 21), and for convenience of description, the end portion where the first conductor insert 21 is located is denoted as a front end, the first conductor insert 21 extends axially forward by a predetermined length, that is, the length of the first conductor insert 21.

An elastic member and a plurality of first conductor segments 31 are provided in addition to the first conductor insert 21, and the elastic member is limited between the first conductor insert 21 and each of the first conductor segments 31.

The rear end sections of the first conductor segments 31 near the rear ends are connected to the first conductor base 11 by the first pin portions 41, the front ends of the first conductor segments 31 extend forward so as to be in the same direction as the longitudinal direction of the first conductor insert 21 with a certain interval, the first conductor segments 31 are located on the outer periphery of the first conductor insert 21, and the elastic members are spaced in the interval between the first conductor segments 31 and the first conductor insert 21.

In use, when the connector of the present embodiment is inserted into the insertion hole having a smaller diameter than the outer diameter of the connector of the present embodiment, each first conductor tab 31 is subjected to radially inward pressure, and each first conductor tab 31 slides along the first pin portion 41 to which it is connected, so that each first conductor tab 31 moves in a direction approaching the first conductor insert 21, the distance between each first conductor tab 31 and the first conductor insert 21 decreases, and the elastic member is in an elastically compressed state under the pressure of each first conductor tab 31. In this process, the outer diameter of the socket end constituted by the first conductor insert 21 and each first conductor tab 31 on the outer periphery thereof is reduced to fit the aperture of the current jack. The outer diameter of the spigot end is D0 in a natural state, and the outer diameter of the spigot end after extrusion is D1, wherein D1 is less than D0.

After the socket pipe is pulled out of the insertion hole, the external force is removed, the elastic member is elastically restored, and the first conductor flaps 31 are moved away from the first conductor insert 21 by the elastic force until the elastic force is removed, and the outer diameter of the socket is restored to the original shape of D0.

From the above, the connector of the present embodiment is used as a male connector, and the connector can be adaptively adapted to a receptacle having a smaller aperture than the outer diameter of the connector of the present embodiment, and after the connector is plugged, the elastic member maintains a compressed state, and has a pressure towards the hole wall direction on each first conductor lobe 31 on the periphery, which is beneficial to improving the contact tightness between each first conductor lobe 31 and the receptacle, and improving the reliability of the connector. And the jack that the grafting of this embodiment can adapt certain aperture scope, the aperture is the smaller, and the compression degree of elastomeric element is the greater.

As an illustration of the present embodiment, a wire connection portion 5 for wire connection may be provided at the rear end of the first conductor base 11, wherein the wire connection portion 5 may be a welding position for wire welding, or may be a connection structure for wire riveting or other connection. See the prior art for details.

As an illustration of the present embodiment, another conductor insert or conductor insertion hole protruding from the first conductor base 11 may also be provided at the rear end (or laterally) of the first conductor base 11. The structure of the protruding conductor insert may be the same as that of the first conductor insert 21, or may be a conductor insert of a prior art structure; the conductor jack may be the first conductor jack 2 described in embodiment 2 or a conductor jack of a prior art structure for circuit switching at the back end.

As an illustration of the present embodiment, the first conductor base 11, the first conductor insert 21, and the wiring portion 5 (or the conductor insert or the conductor insertion hole) of the present embodiment are formed as an integrated structure, and may be, but not limited to, formed of a copper member.

As an illustration of the present embodiment, the first conductor insert 21 may be, but is not limited to, designed in a tubular shape with an axial center being hollow. As an illustration of the present embodiment, it is also possible, but not limited to, to design the wall thickness of the tube everywhere of the first conductor insert 21 to be uniform.

As an illustration of this embodiment, a plurality of slots penetrating the tube wall may be formed in the tube wall of the first conductor insert 21. Each slot penetrates the pipe wall, and extends from the root (or the vicinity of the root) of the first conductor insert 21 connected to the first conductor base 11 to the tip in the axial direction of the first conductor insert 21, and an opening is formed at the tip to divide the first conductor insert 21 into a plurality of separate conductor tabs extending in the axial direction. In this way, the connector of the present embodiment may be used in a female connector, and when the conductor connector is inserted into the pipe diameter of the first conductor connector 21 of the present embodiment during the female connector application, under the effect of the expansion force of the inserted conductor connector, each conductor insert of the first conductor connector 21 is elastically deformed and expands outwards, and the inner wall of the first conductor connector 21 is closely attached to the outer wall of the inserted conductor connector, thereby realizing the female connector application. And in the process of plugging, when the conductor inserting piece of the first conductor inserting piece 21 expands outwards, the elastic component has a reaction force on the conductor inserting piece, so that the plugging tightness is improved, the plug can adapt to the male plug with a sizing range, and the larger the aperture of the male plug of the plug is, the larger the compression degree of the elastic component is.

In summary, the connector of the embodiment can be used as a male connector or a female connector. And can adapt to the plug-in and jack with a certain aperture range.

As an illustration of the present embodiment, the slots may be, but not limited to, symmetrically and uniformly distributed on the first conductor insert 21 with respect to the axis of the first conductor insert 21, and the shape and elasticity of the conductor inserts may be the same.

In the connector of the present embodiment, only the first conductor base 11 may be provided on the insulating base of the connector, so that a terminal connection is realized by a connector. Thus, when the positive electrode and the negative electrode (or the ground electrode) of the circuit (or the power supply) are required to be connected and inserted, two (or three) independent connectors are respectively adopted to complete the independent connection and the connection of the two electrodes (or three if the ground wire is also provided) so as to realize the connection and the switching of the power supply.

In addition, as an alternative to the present embodiment, as shown in fig. 15, other conductor bases insulated from the first conductor base 11 may be further provided on the insulating base of a connector, in addition to the first conductor base 11 described in the present embodiment. A conductor plug or a conductor jack is provided on each conductor base, respectively, so that the switching or connection of a plurality of electrodes can be completed on one connector.

As an illustration of the present embodiment, the axial extension line of each first pin portion 41 provided at the rear end of the first conductor insert 21 intersects the axis of the first conductor insert 21, and the rear end section of each first conductor tab 31 is inserted through each first pin portion 41, and at this time, the direction in which each first conductor tab 31 slides along the first pin portion 41 to which it is connected is the radial direction of the first conductor insert 21. The front end sections of the first conductor segments 31 are respectively extended forward and distributed on the outer periphery of the first conductor insert 21, and the elastic members are spaced between the first conductor segments 31 and the first conductor insert 21.

As an illustration of the present embodiment, the first conductor segments 31 may be, but not limited to, uniformly distributed on the outer periphery of the first conductor insert 21 with the same pitch between the first conductor segments 31.

As an illustration of the present embodiment, the elastic component of the present embodiment may be, but is not limited to, implemented by using a plurality of elastic pieces 6, where the middle part of each elastic piece 6 is fixed on the outer wall of the first conductor insert 21, the front end and the rear end of each elastic piece 6 are free ends that can be freely stretched, and opposite sides of each elastic piece 6 are respectively abutted against the first conductor flap 31 and the first conductor insert 21, when the elastic piece 6 is pressed, the height of the elastic piece 6 is reduced, the two ends of the elastic piece 6 extend outwards, and the length of the elastic piece 6 is prolonged; when the external force disappears, the elastic sheet 6 recovers the deformation, the height becomes large, and the length becomes short.

As an illustration of the present embodiment, each first conductor tab 31 extends outside each spring 6, and each spring 6 is spaced in a gap between each first conductor tab 31 and the first conductor insert 21, and an outward side surface of each spring 6 abuts against an inward side of each first conductor tab 31. The principle of application is that when each first conductor flap 31 receives inward pressure, each first conductor flap 31 is retracted inwards respectively, so that the gap between each first conductor flap 31 and the first conductor plug 21 is reduced, each spring 6 receives inward pressure, and under the action of the pressure, the front end and the rear end of each spring 6 are respectively stretched back and forth, so that the height of each spring 6 between the first conductor plug 21 and the first conductor flap 31 is reduced, the gap between the first conductor flap 31 and the first conductor plug 21 is reduced, the diameter of the connector is adaptively reduced to the current size of the plug hole, and the tight connection between the connector and the plug hole is maintained under the elastic force of the spring 6, thereby ensuring the reliability of the connector. From the above, the spring plate 6 structure of the embodiment can adapt to the jacks with different apertures adaptively.

As an illustration of the present embodiment, each of the elastic pieces 6 in the present embodiment may be, but not limited to, a straight piece with a middle portion closely attached to the outer periphery of the first conductor insert 21, and the elastic pieces 6 located at two sides of the straight piece are curved in a repeatedly bent manner such as a wavy manner or a zigzag manner, wherein the length of the straight piece in the middle is preferably designed to be shorter, and the wavy manner or the zigzag manner at two ends is preferably designed to be longer, so as to ensure a higher elastic coefficient of the elastic piece 6, and improve the elastic strength and the durability of the elastic piece 6.

As an illustration of the present embodiment, both ends of the spring piece 6 may be, but are not limited to, curved with a crest against the first conductor tab 31 and a trough against the first conductor insert 21, curved with only a crest against the first conductor tab 31, or curved with only a trough against the first conductor insert 21.

As an illustration of the present embodiment, it is preferable, but not limited, to make the end of each first conductor tab 31 protruding outside the first conductor insert 21 protrude beyond the end of the first conductor insert 21. Thus, when inserting into the insertion hole, the distal end of each first conductor tab 31 is first brought into contact with the insertion hole, where the space between each first conductor tab 31 is empty and is easily retracted into the insertion hole, improving the convenience of the insertion of the connector of the present embodiment.

As an illustration of this embodiment, it is also possible, but not limited to, that the ends of the first conductor flaps 31 are respectively bent inwards to form the blocking pieces located at the front ends of the first conductor inserts 21, that the blocking pieces are respectively located at the front ends of the end faces of the ends of the first conductor inserts 21, that a predetermined gap is provided between the blocking pieces and the front ends of the first conductor inserts 21, and that a predetermined distance is provided between the blocking pieces, preferably, but not limited to, that the blocking pieces are designed to stop the folding of the connectors when the first conductor flaps 31 are compressed inwards to contract the ends of the blocking pieces against each other, so as to avoid damage caused by the spring compression exceeding the limit. That design is advantageous for extending the useful life of the present connector.

As an illustration of this embodiment, a first boss 311 is further provided on the inner side surface of each first conductor tab 31, which faces the first conductor insert 21, at the rear end section of each first conductor tab 31 near the rear end, and when the first conductor tab 31 is pinned to the first conductor base 11, the first pin 41 penetrates the section of the first conductor tab 31 where the first boss 311 is located, and the front end of the first conductor tab 31, which is offset relatively outward from the first boss 311, extends out of the first conductor insert 21.

The thickness of the first conductor tab 31 penetrating the first pin portion 41 is smaller than the length of the first pin portion 41, so that the first conductor tab 31 can slide in the axial direction of the first pin portion 41. The rear end position of each first conductor tab 31 is defined by the first pin portion 41, and the front end is defined by each spring piece 6 inside thereof.

As an illustration of this embodiment, the rear end section and the outer side surface of each first conductor tab 31 are further provided with a first recess 312 (or a recess, this embodiment is exemplified by, but not limited to, the first recess 312), and the first recess 312 is opposite to the first boss 311 thereof, so that the first pin 41 penetrates through the first recess 312, the thickness of the first conductor tab 31 at the position penetrating through the first pin 41 is relatively thinner, and the distance between the pin connection part at the rear end and the first conductor insert 21 is closer than the distance between the protruding section at the front end and the first conductor insert 21, which is beneficial to improving the movement stability and balance of the first conductor tab 31.

As an illustration of this embodiment, but not limited to, the first groove 312 may be designed to be wider, so that the first pin portion 41 and the groove edge of the first groove 312 where the first pin portion is located have a predetermined gap, thereby enabling the first conductor flap 31 to perform a rotational movement with a certain angle with respect to the first pin portion 41, and enabling the adaptive movement of the first conductor flap 31 to be more flexible.

As an illustration of the present embodiment, but not limited to, the hole portion of the first conductor tab 31 for penetrating the first pin portion 41 is slightly larger than the diameter of the first pin portion 41, so that each first conductor tab 31 can move back and forth to a certain extent with respect to the pin in which it is located, and the adaptive movement of the first conductor tab 31 is more flexible.

As an illustration of the present embodiment, a first ring-shaped fixing base 12 surrounding the first conductor base 11 may be provided at the outer periphery of the first conductor base 11 with a predetermined interval between the first ring-shaped fixing base 12 and the first conductor base 11, and a first rib portion 13 for fixing the first ring-shaped fixing base 12 to the outer periphery of the first conductor base 11 may be connected between the first ring-shaped fixing base 12 and the first conductor base 11, wherein the first rib portion 13 and the first ring-shaped fixing base 12 may be, but are not limited to, a structure integral with the first conductor base 11, and the first rib portion 13 may be one or more. In this way, the first pin 41 can be fixed to the first annular holder 12 and the first conductor base 11 at both ends, and the rear end sections of the first conductor flaps 31 extend into the gaps between the first annular holder 12 and the first conductor base 11, respectively, and are pinned to the first pin 41. The rear end sections of the first conductor segments 31 are respectively pinned to the outer periphery of the first conductor base 11. The connector adopting the technical scheme has compact structure and good integration.

The connector of the embodiment can be arranged on the battery pack and used as an external power connector of the battery pack for providing power for the outside; the battery pack can also be used as serial-parallel connection and insertion among battery pack modules in the battery pack, so that the combination of the battery packs is realized.

The connector of the embodiment may also be disposed on a power charger as a connection between the charger and an electrode of the battery pack to charge the battery pack.

The connector of the embodiment can also be applied to an electronic product adopting a battery as a power supply, and can be used as a connector between the electronic product and the power supply.

Example 2

See fig. 14-23.

The present embodiment provides a connector commonly referred to as a female connector.

The connector of the present embodiment includes an insulation base (not shown) that has been insulation protected and is handled by a user, and one or more second conductor bases 81 are disposed on the insulation base, wherein the directions of the second conductor bases 81 may be the same direction, or may be opposite directions, or may be partially in a front-rear direction, or partially in a left-right direction. And are not limited herein. The second conductor base 81 provided with the first conductor insertion hole 71 of the present embodiment will be hereinafter referred to as a second conductor base 81.

The second conductor base 81 is provided with a conductor jack (denoted as a first conductor jack 71) provided in this embodiment, and the end of the first conductor jack 71 where the jack is located is denoted as the front end of the connector, and the first conductor jack 71 extends from the front end jack to a certain depth along the rear end.

An elastic member and a plurality of second conductor flaps 22 are also provided in the first conductor insert 1.

The rear end sections of the respective second conductor segments 22 are connected to the rear ends of the first and second conductor bases 81 by the second pin portions 42, respectively, while the front end sections of the respective second conductor segments 22 protrude into the first conductor insertion holes 71, respectively, the respective second conductor segments 22 extend in the axial direction of the first conductor insertion holes 71, and the elastic members are spaced between the respective second conductor segments 22 and the first conductor insertion pieces.

The principle of application is that when the aperture is larger than the aperture between the second conductor flaps 22 of the present embodiment, and when the second conductor flaps 22 are subjected to radially outward pressure, the rear end sections of the second conductor flaps 22 slide along the second pin portions 42 to which they are connected, causing the second conductor flaps 22 to move outward, the distance between the second conductor flaps 22 and the inner wall of the first conductor insertion hole 71 is reduced, and the elastic member is placed in an elastically compressed state. The elastic member in a compressed state has a radially inward elastic force on each second conductor tab 22, and the second conductor tabs 22 are abutted against the outer periphery of the inserted insert, in close contact. During the plugging process, the aperture of the plugging end constituted by the first conductor insertion hole 71 and each second conductor flap 22 of the inner periphery thereof is reduced to be adapted to the aperture of the current insertion hole. The aperture of the spigot end is D0 when the spigot is in a natural state, and the aperture of the spigot end after extrusion is D1, D1> D0.

After the connector is pulled out, the external force disappears, the elastic component is elastically restored, and each second conductor flap 22 is restored inwards under the action of the elastic force until the elastic force disappears, and the hole of the connector is restored to the original state of D0.

From the above, the connector of the present embodiment is used as a female connector, and the connector can be adaptively adapted to a connector having an outer diameter larger than that of the connector of the present embodiment, and after the connector is inserted, the elastic member maintains a compressed state, and has a radial inward pressure on each second conductor lobe 22 on the inner periphery, so that each second conductor lobe 22 is in close contact with the inserted connector, which is beneficial to improving the contact tightness between each second conductor lobe 22 and the connector, and improving the reliability of the connector. And the female plug-in of this embodiment can adapt the plug-in of a certain external diameter range, and the bigger the external diameter of plug-in, the bigger the compression degree of elastic component.

As an illustration of the present embodiment, the axial extension line of each second pin portion 42 provided at the rear end of the first conductor insertion hole 71 intersects the axis of the first conductor insertion hole 71, and the rear end section of each second conductor tab 22 is inserted through each second pin portion 42, and at this time, the direction in which each second conductor tab 22 slides along the second pin portion 42 to which it is connected is the radial direction of the first conductor insert. The front end sections of the second conductor flaps 22 are respectively extended forward and distributed on the inner periphery of the first conductor insertion space, and the elastic members are spaced between the second conductor flaps 22 and the first conductor insertion space.

As an illustration of the present embodiment, the second conductor lobes 22 may be, but not limited to, uniformly distributed on the inner periphery of the first conductor insert, with the pitches between the second conductor lobes 22 being the same.

As an illustration of the present embodiment, the elastic component of the present embodiment may be, but is not limited to, implemented by using a plurality of elastic pieces 6, where the middle part of each elastic piece 6 is fixed on the inner wall of the first conductor jack 71, the front end and the rear end of each elastic piece 6 are free ends that can be freely stretched, and opposite sides of each elastic piece 6 are respectively abutted against the second conductor flap 22 and the first conductor plug, when the elastic piece 6 is pressed, the height of the elastic piece 6 is reduced, the two ends of the elastic piece 6 extend outwards, and the length of the elastic piece 6 is prolonged; when the external force disappears, the elastic sheet 6 recovers the deformation, the height becomes large, and the length becomes short.

As an illustration of the present embodiment, the second conductor segments 22 extend outside the elastic pieces 6, the elastic pieces 6 are spaced in the gaps between the second conductor segments 22 and the first conductor insertion holes 71, respectively, and the inward side surfaces of the elastic pieces 6 are abutted against the second conductor segments 22, and the outward side surfaces are abutted against the inner walls of the first conductor insertion holes 71. The principle of application is that when each second conductor flap 22 receives outward pressure, each second conductor flap 22 expands outwards, so that the gap between each second conductor flap 22 and the first conductor plug is reduced, each spring 6 receives inward pressure, and under the action of the pressure, the front end and the rear end of each spring 6 extend forwards and backwards respectively, so that the height of each spring 6 between the first conductor plug and the second conductor flap 22 is reduced, the gap between the second conductor flap 22 and the first conductor plug is reduced, the diameter of the connector is reduced to the size of the current plug, and the tight connection between each second conductor flap 22 and the inserted plug of the connector of the embodiment is maintained under the elastic force of the spring 6, so that the reliability of the connector is ensured. From the above, the spring plate 6 structure of the embodiment can adapt to the plug-in components with different apertures adaptively.

As an illustration of the present embodiment, each of the elastic pieces 6 in the present embodiment may be, but not limited to, a straight piece with a middle portion that is tightly attached to the inner wall of the first conductor jack 71, and the elastic pieces 6 located at two sides of the straight piece are curved in a repeatedly bending manner such as a wavy manner or a zigzag manner, wherein the length of the straight piece in the middle is preferably designed to be shorter, and the wavy manner or the zigzag manner at two ends is designed to be longer, so as to ensure a higher elastic coefficient of the elastic piece 6, and improve the elastic strength and the durability of the elastic piece 6.

As an illustration of the present embodiment, both ends of the spring piece 6 may be designed, but not limited to, as a curve having a peak against the second conductor tab 22 and a trough against the inner wall of the first conductor insertion hole 71, as a curve having only a peak against the second conductor tab 22, or as a curve having only a trough against the first conductor insertion piece.

As an illustration of the present embodiment, it is preferable, but not limited, to have the distal end of each second conductor tab 22 protrude beyond the first conductor insertion hole 71. Thus, when the connector is plugged with an external connector, the distal end of each second conductor tab 22 is first brought into contact with the inserted connector, where the outer portion of each second conductor tab 22 is easily expanded outward to facilitate insertion of the connector, improving the convenience of the connector of the present embodiment.

As an illustration of the present embodiment, the distal ends of the second conductor segments 22 may be folded outwardly to form a stopper piece located at the front end of the distal end face of the first conductor insertion hole 71. The respective blocking pieces have predetermined gaps with the end faces of the distal ends of the first conductor insertion holes 71, respectively, and the adoption of this design is advantageous in improving the convenience of the female plug and the external plug of the present embodiment.

As an illustration of this embodiment, the groove 222 may be, but is not limited to, designed to be wider, so that the second pin portion 42 has a predetermined gap with the groove edge of the groove 222 where the second pin portion is located, thereby enabling the second conductor flap 22 to perform a rotational movement with respect to the second pin portion 42 at a certain angle in a plane perpendicular to the axial direction, and making the adaptive movement of the second conductor flap 22 more flexible.

As an illustration of this embodiment, but not limited to, the hole portion of the second conductor tab 22 for penetrating the second pin portion 42 is slightly larger than the diameter of the second pin portion 42, so that each second conductor tab 22 can be offset to a certain extent with respect to the pin in which it is located, and the adaptive movement of the second conductor tab 22 is more flexible.
