Disclosure of Invention

In view of the above, the present invention provides an adapter and a rail-type socket having the same, which are used for facilitating the installation and removal of the adapter on and from a rail.

In a first aspect, in one embodiment of an adapter for a rail-type socket provided by the present invention, the adapter includes a base, and a conductive pin, a main gear, two sub gears, an adjusting ring driving the conductive pin to swing and retract, and a middle seat disposed on the base. The base is provided with a limiting plate extending out from the bottom of the base, two windows are arranged on the limiting plate at intervals along the length direction extending along the bottom surface of the base, and the two windows are respectively located on two opposite sides of the limiting plate. Each conductive pin comprises a conductive shaft and a conductive inserting sheet extending from the side wall of the conductive shaft; the two conductive inserting sheets are respectively arranged in one of the two windows, and one end of the conductive shaft extends out of the top surface of the base. The main gear and the two auxiliary gears are arranged on the top surface of the base, the two auxiliary gears are respectively connected to one conductive shaft, and the main gear and the two auxiliary gears are meshed for transmission. The adjusting ring is arranged on the top surface of the base and connected with the main gear, so that the two conductive inserting sheets are driven to swing synchronously by driving the main gear to rotate coaxially, and the tail ends of the two conductive inserting sheets can extend out from the corresponding windows in opposite directions; the middle seat is connected to the top surface of the base and is positioned in the adjusting ring; the two conductive shafts extend out of the middle seat, and the middle seat is further arranged to limit the two pinion gears in the axial direction of the pinion gears.

Illustratively, in a rail-type socket, the adapter is required to mate with a rail plate. In order to make it easier for the skilled person to understand the construction of the above-described adapter, a track plate is described here as an example. For example, an installation space is formed in the track plate, a conductive plug bush is arranged on the left side wall and the right side wall of the installation space, and a limit opening for the limit plate of the adapter to extend into and slide is formed in the top wall of the installation space.

The limiting plate of the adapter can extend into the installation space of the track plate from the limiting opening on the track plate, and the adapter can slide along the track plate. By arranging a main gear and two auxiliary gears between the adjusting ring and the conductive shaft of the conductive pin, the adjusting ring can adjust the position of the conductive inserting piece of the conductive pin through rotating relative to the base. Wherein the two conductive inserts can be kept parallel and opposite in direction all the time in the swinging process. The angle at which the two conductor tabs are pivoted between the two extreme positions can be adapted in particular, for example, to any angle between 30 ° and 90 °, preferably 45 °.

The adjustment ring may be rotated to position the conductive tabs within the stop plate prior to installation of the adapter on the track plate, where the ends of the two conductive tabs may be opposite and the two conductive tabs may be in the same line. When the adapter is mounted to the track plate, rotation of the adjustment ring simultaneously drives the two conductive pins to rotate such that one conductive tab extends from one window and is inserted into the conductive insert on the left side wall of the track plate and the other conductive tab extends from the other side of the other window and is inserted into the conductive insert on the right side wall of the track plate. When the two conductive inserting sheets extend out from the two sides of the limiting plate towards opposite directions, the adapter and the track plate are electrically connected. Meanwhile, due to the plugging effect of the conductive inserting sheets and the conductive inserting sleeves, the adapter can be firmly installed on the track plate.

Illustratively, in the two-hole socket embodiment, the adapter further comprises at least two electrical connectors, corresponding to the two conductive pins described above, disposed above the central seat and adapted to be electrically connected to an external plug; the electric connector is provided with two elastic contact pieces, the two elastic contact pieces are bent in opposite directions and are provided with opposite concave arc parts, and the two concave arc parts are clamped on the annular side wall of the conductive shaft. In this way, the conduction shaft of the conduction pin and the concave arc part of the electric connector are in rotary connection to realize conduction.

Preferably, in the three-hole socket embodiment, a conductive plug bush is further disposed on the bottom wall of the installation space. Correspondingly, the adapter further comprises a grounding insertion piece and an electric connecting piece connected with the grounding insertion piece, wherein the grounding insertion piece can penetrate through the through hole and extend out of the bottom surface of the limiting plate, and the grounding insertion piece is in insertion connection with a conductive insertion sleeve arranged on the bottom wall of the installation space.

In a preferred implementation of the adapter provided in the foregoing embodiment, in order to more conveniently dispose the conductive pin on the base, the top surface of the base is further provided with two notches, which respectively and correspondingly communicate with the two windows. Simultaneously, the adapter also comprises an inner seat, wherein the inner seat is provided with two inserts, the two inserts are respectively inserted into the limiting plate through two notches and respectively correspond to one window, and a gap for the conductive inserting piece to swing is formed between the two inserts and the inner bottom surface of the limiting plate; wherein the inner seat is further configured to rotatably position two of the conductive pins on the base.

For example, two sidewalls of the two notches relatively far away may be respectively formed with a first half ring groove, and two sidewalls of the two inserts relatively far away are respectively formed with a second half ring groove, and the second half ring groove is combined with the first half ring groove to form a limiting hole for the conductive shaft to pass through. In the installation process of the conductive pin, the conductive inserting sheets of the conductive pin can be respectively arranged in the corresponding windows from the two notches, the conductive shaft of the conductive pin is close to the first half ring groove, and then the inner seat is arranged to be respectively inserted into the two notches by the two inserting blocks, so that the installation of the two conductive pins is completed.

For another example, two limiting holes may be formed in the inner seat, and the two limiting holes are respectively provided for the two conductive shafts to pass through, so that the two conductive pins are rotatably disposed on the base.

It should be noted that, in addition to the installation of the conductive pin by matching with the inner seat, the conductive shaft of the conductive pin and the conductive insert may be detachably connected, for example, a connection hole is provided on the conductive insert and is in interference fit with the conductive shaft, or one end of the conductive shaft is in threaded connection with the conductive insert. Thus, the purpose of installing the conductive pin on the base is achieved.

In a preferred implementation manner of the adapter provided in the foregoing embodiment, the inner seat is further provided with a round table, and the round table is in rotation fit with the shaft hole of the main gear. At this time, the round table on the inner seat is used as a rotating shaft of the main gear so as to keep the main gear and the base to be connected in a relative rotating way. Further, in the three-hole socket embodiment, a through hole is further formed on the circular truncated cone, and the grounding insert may pass through the through hole and protrude from the bottom surface of the limiting plate.

In a preferred implementation of the adapter provided in the foregoing embodiment, at least one mounting bracket may be disposed on an inner wall of the adjusting ring, and the mounting bracket is formed with a slot facing the base; at least one connecting end of the main gear extends to be close to the inner wall of the adjusting ring, and the connecting end is provided with an inserting block, and the inserting block is in inserting fit with the inserting groove, so that the adjusting ring is coaxially connected with the main gear. Therefore, in the process of rotating the adjusting ring by hand, the adjusting ring can drive the main gear to rotate, and the conductive pin is further driven to rotate. The outer side of the middle seat is adaptively provided with an arc-shaped concave cavity, and the arc-shaped concave cavity is arranged to be a movable space required by the mounting frame when the adjusting ring rotates.

It should be noted that, the connection manner between the adjusting ring and the main gear is not limited to the present embodiment, as long as the purpose of synchronous rotation of the adjusting ring driving main gear can be achieved, all fall within the scope of the present invention. For example, a connecting rod extending in the radial direction of the main gear may be connected between the adjusting ring and the main gear to achieve the purpose of synchronous rotation of the adjusting ring driving main gear.

Preferably, a plurality of electrical connectors may be further provided on the top surface of the intermediate seat, through which the above-mentioned one main gear and two sub gears are isolated between the base and the intermediate seat. In addition, the top cover of the adapter is also connected to the middle seat through a buckle or a screw, and the top cover is provided with a jack matched with the plug according to the requirements of the two-hole socket or the three-hole socket. It will be appreciated that during rotation of the adjustment ring, the top cover, the middle base and the base remain relatively fixed throughout, while the adjustment ring rotates relative to them and drives the conductive pin to rotate.

In a preferred implementation of the adapter provided by the above embodiment, the top wall of the middle seat is further formed with an arc-shaped groove, for example, the arc-shaped groove may be disposed on the top surface of the arc-shaped concave cavity. And the connecting end of the main gear is also provided with a baffle rod which is used for extending into the arc-shaped groove so as to limit the rotation range of the main gear to be matched with the swinging range of the two conductive inserting sheets. Therefore, the problem that the adapter is damaged due to overlarge rotating angle of the conductive pin caused by misoperation can be avoided, and meanwhile, the conductive pin can rotate in a required range conveniently, so that the adapter can be disassembled and assembled conveniently, and the adapter is electrically connected with the track plate conveniently.

In addition to limiting the range of rotation of the conductive pin by providing a lever on the main gear as described above, other solutions are possible to achieve this. For example, in a preferred embodiment of the above adapter, the base is provided with at least one pair of positioning rods, and a screw is passed through a central hole of the positioning rod and connected to the middle seat. The pair of positioning rods are respectively positioned at two sides of the main gear so as to limit the rotation range of the main gear to be matched with the swing range of the two conductive inserting sheets. In this embodiment, the positioning lever is used not only to connect the base and the center, but also to limit the rotation range of the conductive pin, and the rotation range of the conductive pin can be limited without providing a stopper for the main gear.

Preferably, the main gear is plate-shaped, two sides of the main gear are respectively provided with an arc-shaped concave surface, and the two arc-shaped concave surfaces are respectively matched with a corresponding positioning rod. Therefore, the rotation range of the conductive pin can be more accurately limited through the arc concave surface, and meanwhile, the effect of protecting the main gear can be achieved through the design of the arc concave surface on the main gear, so that the damage caused by collision between the main gear and the positioning rod is avoided.

In a second aspect, the present invention also provides a rail receptacle comprising at least one adapter of any of the embodiments described above and a rail plate. The mounting space is formed in the track plate, a conductive plug bush is arranged on the left side wall, the right side wall and the bottom wall of the mounting space, and a limiting opening for the limiting plate of the adapter to extend into and slide is formed in the top wall of the mounting space; the two conductive plug bushes arranged on the left side wall and the right side wall of the installation space are respectively connected with one conductive plug bush of the adapter in an inserting manner, and the conductive plug bushes arranged on the bottom wall of the installation space are connected with the grounding plug bush of the adapter in an inserting manner. Thus, the whole track type socket using the adapter is more convenient and reliable in use.

As shown in fig. 1, the track type socket of the present embodiment includes a track plate 9 and an adapter 10 slidably provided on the track plate 9.

With continued reference to fig. 1, an installation space 91 is formed in the track plate 9, a conductive socket 92 is disposed on the left side wall, the right side wall and the bottom wall of the installation space 91, and a limiting opening 911 is formed on the top wall of the installation space 91.

As can be seen in fig. 1, the adapter 10 comprises a base 1, an adjusting ring 4 and a top cover 13. The base 1 is connected to the cover 13 in a relatively fixed manner, while the adjusting ring 4 is rotatable relative to the base 1. The bottom of the base 1 is provided with a limiting plate 11 which extends from a limiting opening 911 on the track plate and can slide along the limiting opening 911.

After the adapter 10 is mounted on the track plate 9, by rotating the adjusting ring 4, a conductive insert 22 extends from both the left and right sides of the limiting plate 11 of the adapter 10 to be respectively plugged into and electrically connected with conductive plugs 92 on the left and right side walls of the mounting space 91, so that electricity can be taken out when the plug is plugged into the jack of the top cover 13. In addition, for the three-hole socket, the bottom of the limiting plate 11 of the adapter 10 is also provided with a grounding insert 8 which is inserted into and electrically connected with the conductive insert 92 arranged on the bottom wall of the installation space 91, so as to realize the grounding of the electric equipment. Such a rail-type socket has the advantage of facilitating the mounting and dismounting of the adapter 10 to and from the rail.

The above-described method of using the rail type socket of the present embodiment is exemplified, and the detailed structure of the adapter 10 and the advantages of using the rail type socket as a whole using the adapter 10 will be described in detail.

With continued reference to fig. 2, the adapter 10 essentially comprises a base 1 and two conductive pins 2 arranged on the base 1, a main gear 31, two secondary gears 32, an adjusting ring 4 driving the conductive pins 2 to oscillate and expand, and a middle seat 5.

As can be seen in fig. 1 and 2, the base 1 has a limiting plate 11 extending from the bottom thereof, and the limiting plate 11 is provided with two windows 111 at intervals along the length direction extending along the bottom surface of the base 1, and the two windows 111 are respectively located at two opposite sides of the limiting plate 11.

As can be seen in connection with fig. 1 to 3, each of the two conductive pins 2 comprises a conductive shaft 21 and a conductive tab 22 extending from a side wall of the conductive shaft 21. Two conductive tabs 22 are respectively disposed in one of the two windows 111, and one end of the conductive shaft 21 protrudes from the top surface of the base 1.

Illustratively, referring to fig. 3, in order to more conveniently dispose the conductive pin 2 on the base 1, the top surface of the base 1 is further provided with two notches 112, and the two notches 112 respectively communicate with the two windows 111. Meanwhile, the adapter 10 further comprises an inner seat 6, the inner seat 6 is formed with two inserts 61, the two inserts 61 are respectively inserted into the limiting plate 11 through two notches 112 and respectively correspond to one window 111, and a gap for swinging the conductive insert 22 is formed between the two inserts 61 and the inner bottom surface of the limiting plate 11. Wherein the inner seat 6 is further arranged to rotatably arrange two conductive pins 2 on the base 1.

Illustratively, two sidewalls of the two notches 112, which are relatively far apart, are respectively formed with a first half ring groove 1121, and two sidewalls of the two inserts 61, which are relatively far apart, are respectively formed with a second half ring groove 62, and the second half ring groove 62 is combined with the first half ring groove 1121 to form a limiting hole through which the conductive shaft 21 passes.

During the installation of the conductive pins 2, the conductive insert 22 of the conductive pin 2 may be first placed in the corresponding window 111 by the two notches 112, respectively, and the conductive shaft 21 of the conductive pin 2 is brought close to the first half ring groove 1121, and then the inner seat 6 is set so that the two inserts 61 are inserted into the two notches 112 of the base 1, respectively, to complete the installation of the two conductive pins 2.

For another example, two limiting holes may be further provided on the inner base 6, where the two limiting holes are respectively passed through by two conductive shafts 21, so as to rotatably set the two conductive pins 2 on the base 1.

In addition to the above embodiment of mounting the conductive pin 2 by fitting the inner holder 6, the inner holder 6 and the base 1 may be integrally formed. At this time, the conductive shaft 21 and the conductive tab 22 of the conductive pin 2 may be detachably connected, for example, a connection hole provided on the conductive tab 22 is interference fit with the conductive shaft 21, or one end of the conductive shaft 21 is screwed or clamped with the conductive tab 22. In this way, the purpose of mounting the conductive pin 2 on the base 1 can be achieved.

Referring to fig. 2, a main gear 31 and two sub gears 32 are provided on the top surface of the base 1, and the two sub gears 32 are respectively connected to one conductive shaft 21, and the main gear 31 is engaged with the two sub gears 32.

Illustratively, in connection with fig. 3, the inner seat 6 may further be provided with a circular table 63, and the circular table 63 is in a rotating fit with the shaft hole 314 of the main gear 31. At this time, the circular truncated cone 63 on the inner base 6 serves as a rotation shaft of the main gear 31 to maintain the relatively rotatable connection between the main gear 31 and the base 1. In addition, in the three-hole socket embodiment, a through hole 631 may be formed on the round table 63, and the above-mentioned ground insert 8 may pass through the through hole 631 and protrude from the bottom surface of the limiting plate 11.

With continued reference to fig. 2, an adjusting ring 4 is provided on the top surface of the base 1 and is connected to the main gear 31 to drive the two conductive tabs 22 to swing synchronously by driving the main gear 31 to rotate coaxially, and to enable the ends of the two conductive tabs 22 to protrude in opposite directions from the respective windows 111.

Preferably, with continued reference to fig. 2, at least one connecting end of the main gear 31 extends close to the inner wall of the adjusting ring 4, and is provided with an insert 311. Correspondingly, at least one mounting frame 41 may be disposed on the inner wall of the adjusting ring 4, and the mounting frame 41 is formed with a slot 411 facing the base 1, so that the insert block 311 and the slot 411 can be in plug-in fit, and the coaxial connection between the adjusting ring 4 and the main gear 31 is realized. Thus, in the process of rotating the adjusting ring 4 by hand, the adjusting ring 4 can drive the main gear 31 to rotate, thereby further driving the conductive pin 2 to rotate.

It should be noted that the connection between the adjusting ring 4 and the main gear 31 is not limited to the structure shown in fig. 2, and the purpose of enabling the adjusting ring 4 to drive the main gear 31 to rotate synchronously falls within the scope of the present invention.

For example, a connecting rod extending along the radial direction of the main gear 31 may be connected between the adjusting ring 4 and the main gear 31, so as to achieve the purpose that the adjusting ring 4 drives the main gear 31 to rotate synchronously. For another example, a block may be provided on the mounting frame 41 of the adjusting ring and a block may be provided at a connection end of the main gear 31 to achieve the insertion.

In addition, although the main gear 31 has only one connecting end as an example, the main gear 31 of the present invention may be formed with an insert block 311 at both ends, and accordingly, two mounting frames 41 are formed on the inner wall of the adjusting ring 4, so that the connection between the adjusting ring 4 and the main gear 31 is further ensured by two connecting positions, as shown in fig. 2 and 3.

Referring to fig. 3 and 4, a middle seat 5 is coupled to the top surface of the base 1 and is located inside the adjustment ring 4. The above-mentioned one main gear 31 and two sub gears 32 can be isolated between the base 1 and the center seat 5 by the center seat 5. Wherein the two conductive shafts 21 extend out of the middle seat 5, the middle seat 5 is further arranged to limit the two pinions 32 in the axial direction of the pinions 32.

As can be seen from the above, by providing one main gear 31 and two sub gears 32 between the adjusting ring 4 and the conductive shaft 21 of the conductive pin 2, the position of the conductive tab 22 of the conductive pin 2 can be adjusted by the rotation of the adjusting ring 4 relative to the base 1.

The two conductive tabs 22 can remain parallel and oppositely directed throughout the swing. For example, the adjustment ring 4 may be rotated to position the conductive tabs 22 within the stop plate 11 prior to mounting the adapter 10 to the track plate 9, where the two conductive tabs 22 may be aligned and the ends of the two conductive tabs 22 may be opposite.

When the adapter 10 is mounted to the track plate 9, rotation of the adjustment ring 4 simultaneously drives rotation of the two conductive pins 2 such that one conductive tab 22 extends from one window 111 and is inserted into the conductive sleeve 92 on the left side wall of the track plate 9 and the other conductive tab 22 extends from the other side of the other window 111 and is inserted into the conductive sleeve 92 on the right side wall of the track plate 9. When the two conductive tabs 22 extend from opposite sides of the limiting plate 11, respectively, the adapter 10 is electrically connected to the track plate 9. At the same time, the adapter 10 can be mounted relatively firmly on the track plate 9 due to the plugging action of the conductive plug 22 and the conductive sleeve 92.

Suitably, the outer side of the middle seat 5 is formed with an arc-shaped recess 51, the arc-shaped recess 51 being arranged to adjust the movement space required for the mounting frame 41 when the ring 4 is rotated.

Preferably, the top cover 13 of the adapter 10 is also connected to the middle seat 5 by a buckle or a screw, and the top cover 13 is provided with a jack matched with a plug according to the requirements of a two-hole socket or a three-hole socket. It will be appreciated that during rotation of the adjustment ring 4, the top cover 13, the middle seat 5 and the base 1 remain relatively fixed, while the adjustment ring 4 rotates relative to them and drives the conductive pin 2 to rotate.

In a preferred implementation of the adapter 10 provided in the above embodiment, referring to fig. 3 and 4, the top wall of the middle seat 5 is further formed with an arc-shaped groove 52, for example, the arc-shaped groove 52 may be disposed on the top surface of the arc-shaped cavity 51. And, the connection end of the main gear 31 is further provided with a lever 312, and the lever 312 is used to extend into the arc groove 52 to limit the rotation range of the main gear 31 to match the swing range of the two conductive tabs 22. In this way, the problem that the adapter 10 is damaged due to the fact that the rotating angle of the conductive pin 2 is too large due to misoperation can be avoided, meanwhile, the conductive pin 2 can rotate only in a required range, and the adapter 10 can be disassembled and assembled and electrically connected with the track plate 9 more conveniently.

In addition to limiting the range of rotation of the conductive pin 2 by providing the lever 312 on the main gear 31 as described above, other schemes can be used for this purpose. For example, in a preferred embodiment of the adapter 10 described above, the base 1 is provided with at least one pair of positioning rods 12, and a screw is inserted through the center hole of the positioning rod 12 and connected to the middle seat 5 to connect the base 1 and the middle seat 5 together. Wherein a pair of positioning rods 12 are respectively located at both sides of the main gear 31 to limit the rotation range of the main gear 31 to match the swing range of the two conductive tabs 22. In this embodiment, the positioning lever 12 not only serves to connect the base 1 and the center seat 5, but also has a function of limiting the rotation range of the conductive pin 2, and the rotation range of the conductive pin 2 can be limited without providing the gear lever 312 on the main gear 31.

Preferably, the main gear 31 has a plate shape, and two arc-shaped concave surfaces 313 are respectively formed on two sides of the main gear, and the two arc-shaped concave surfaces 313 are respectively matched with a corresponding positioning rod 12. In this way, the rotation range of the conductive pin 2 can be more precisely limited by the arc concave 313, and meanwhile, the design of the arc concave 313 on the main gear 31 can also play a role in protecting the main gear 31, so as to avoid damage caused by collision between the main gear 31 and the positioning rod 12.

Preferably, the angle at which the two conductive tabs 22 swing between the two extreme positions may be adaptively adjusted in practice, for example, may be any angle between 30 ° and 90 °. For example, 45 ° may be preferable.

Referring to fig. 4, in the two-hole socket embodiment, the adapter 10 further includes at least two electrical connectors 7 corresponding to the two conductive pins 2 described above, the two electrical connectors 7 being disposed on the top surface of the middle socket 5 and being for electrical connection with an external plug. Preferably, the electrical connectors 7 may be formed with two elastic contacts, and the two elastic contacts are bent toward each other and formed with opposite concave arc portions 71, and the two concave arc portions 71 are clamped on the circumferential side wall of the conductive shaft 21. In this way, the conduction is achieved by the rotational connection between the conductive shaft 21 of the conductive pin 2 and the concave arc portion 71 of the electrical connector 7.

Preferably, in the three-hole receptacle embodiment, the adapter 10 further includes an electrical connector 6117 that connects to the ground tab 638.

Specifically, the present invention can achieve the following objects:

first, the position of the conductive insert 22 is adjusted by rotation of the adjustment ring 4 relative to the base 1, thereby facilitating the installation and removal of the adapter 10 from the track plate 9.

Second, through setting up the inserted block 311 at the link that main gear 31 extended to form to and the inserted block 311 is pegged graft with the slot 411 of the mounting bracket 41 on the inner wall of adjusting ring 4, the connection of convenient main gear 31 and adjusting ring 4.

Thirdly, through the cooperation of a shelves lever 312 that sets up at the link of master gear 31 and the arc groove 52 of well seat 5, perhaps set up the locating lever 12 that is located the both sides of master gear 31 respectively on the top surface of base 1, conveniently restrict the rotation scope of electrically conductive round pin 2, can make the dismouting of adapter 10 and the electricity of track board 9 be connected more conveniently.

The invention relates to the technical field of sockets, in particular to an adapter 10 and a track type socket with the same. The adapter 10 essentially comprises a base 1 and two conductive pins 2 arranged on the base 1, a main gear 31, two secondary gears 32, an adjusting ring 4, and a middle seat 5 limiting the two secondary gears 32 in the axial direction. The adjusting ring 4 is connected with the main gear 31 to drive the two conductive tabs 22 to swing synchronously by driving the main gear 31 to rotate coaxially, and to enable the ends of the two conductive tabs 22 to protrude from the respective corresponding windows 111 in opposite directions after the adapter 10 is mounted on the track plate 9 to complete electrical connection with the track plate 9, and to enable the adapter 10 to be mounted on the track plate 9 relatively firmly.
