Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present utility model more apparent, the embodiments of the present utility model will be described in further detail with reference to the accompanying drawings.

The terms "connected" or "connected," and the like, are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", etc. are used merely to indicate relative positional relationships, and when the absolute position of the object to be described is changed, the relative positional relationships may be changed accordingly.

The track receptacle includes a track and an adapter. The adapter includes a power taking portion 102 and a socket portion 101, the power taking portion 102 is for insertion into the inside of the rail, and the adapter has a conductive sheet assembly 2 that can be unfolded and stored in the power taking portion 102, the conductive sheet assembly 2 being for contact with the rail conductive sheet in the rail in an unfolded state. The socket part 101 is located outside the track and has a receptacle for interfacing with a plug.

As shown in fig. 1 and 2, the power take-off portion 102 of the adapter in the related art is composed of two parts, namely, a guide main body 14 and a guide protector 15. The side wall of the guide body 14 has an opening 14a, and both ends of the bottom of the guide body 14 have a cantilever 141, and the cantilever 141 has a mounting hole thereon. The guide protector 15 has a top pillar 151 on both sides.

In assembling the adapter, the shaft 21 of the conductive sheet assembly 2 is first passed through the opening 14a of the side wall of the guide body 14 so that the shaft 21 is aligned with and protrudes into the mounting hole of the cantilever 141. Then, the two posts 151 of the guide protector 15 are connected to the two cantilevers 141, respectively, so that the two posts 151 close the opening 14a and protect the conductive sheet assembly 2.

It can be seen that the assembly process of the above-described adapter is relatively complex. Further, since the cantilever 141 and the jack-post 151 have cantilever structures, the strength is low and the damage is easy. In addition, the gap between the rotation shaft 21 and the cantilever 141, and between the rotation shaft 21 and the top column is large.

To solve the technical problems in the related art, the embodiment of the present disclosure provides an adapter, as shown in fig. 3 and 4, which includes a housing 1, a conductive sheet assembly 2, a socket 3, and a control member 4. The housing 1 has a socket part 101 and a power taking part 102, the socket part 101 has an elongated opening 1011 penetrating the bottom, the power taking part 102 has a recess 1021, and the opening 1011 communicates with the recess 1021. The conductive sheet assembly 2 has a rotation shaft 21 and a conductive sheet 22, and the rotation shaft 21 is parallel to the insertion direction of the power taking portion 102. Wherein, as shown in fig. 4, during the assembly of the adapter, the rotation shaft 21 and the conductive sheet 22 pass through the opening 1011 and extend into the recess 1021. The socket 3 is located at the socket portion 101 and is electrically connected to the conductive sheet 22 through the rotation shaft 21. The control member 4 is located at the socket portion 101, and the control member 4 is used for controlling the conductive sheet 22 to be unfolded or stored relative to the power taking portion 102.

According to the technical scheme provided by the embodiment of the disclosure, through the arrangement of the opening 1011 penetrating through the bottom of the socket part 101 and the arrangement of the groove 1021 communicated with the opening 1011 in the electricity taking part 102, when the adapter is assembled, the conductive sheet component 2 passes through the opening 1011 and stretches into the groove 1021 of the electricity taking part 102, so that the positioning of the electricity taking part 102 can be realized, and the assembly process of the adapter is simplified.

In addition, since the power taking part 102 is no longer required to be composed of the guide main body 14 and the guide protection body 15, the cantilever 141 and the top column 151 with cantilever structures are no longer provided, so that the power taking part 102 has higher strength and is not easy to damage. In addition, the gap between the rotating shaft 21 and the power taking part 102 is also made smaller, so that foreign matters are not easy to extend into the gap, and the adapter is more attractive.

In addition, after the conductive sheet assembly 2 extends into the groove 1021 of the power taking part 102, the gap between the rotating shaft 21 and the power taking part 102 can be reduced, so that the appearance integrity of the adapter is improved, and the adapter is more attractive.

In some examples, the depth of the recess 1021 is greater than the thickness of the conductive sheet 22 such that when the conductive sheet 22 is received in the recess 1021, the outer surface of the conductive sheet 22 is lower than the outer surface of the power take-up 102, thereby allowing the conductive sheet 22 to be fully received in the recess 1021.

After the rotation shaft 21 and the conductive sheet 22 are inserted into the groove 1021, the rotation shaft 21 and the conductive sheet 22 do not occupy all portions of the groove 1021, so that the groove 1021 and the opening 1011 are partially exposed, which makes the adapter easily contaminated by impurities.

To solve this technical problem, in some examples, as shown in fig. 3 and 4, the housing 1 further has a closing plate 103, the closing plate 103 being used to close the portion of the groove 1021 other than the portions of the rotation shaft 21 and the conductive sheet 22 after the rotation shaft 21 and the conductive sheet 22 are inserted into the groove 1021. In this way, the gap between the power taking portion 102 and the rail groove can be reduced, and the impurities entering the groove 1021 can be reduced. In addition, the closing plate 103 is also used to close the portion of the opening 1011 other than the portion where the rotation shaft 21 is located.

The embodiment of the present disclosure is not limited to the forming manner of the sealing plate 103, and in some examples, the sealing plate 103 is a separate component, and the sealing plate 103 is directly placed in the groove 1021 after the rotating shaft 21 and the conductive sheet 22 extend into the groove 1021. For example, the closing plate 103 is fastened to the recess 1021.

In other examples, as shown in fig. 3, the housing 1 includes a base 11, a plug mount 12, and a faceplate 13. The base 11 has a connection portion 111 and a power taking portion 102, the connection portion 111 forms a part of the socket portion 101, and the connection portion 111 has an opening 1011. The plug bush 3 is fixed to the plug bush mounting seat 12, and the plug bush mounting seat 12 has a closing plate 103, wherein after the conductive sheet 22 is inserted into the groove 1021, the closing plate 103 passes through the opening 1011 and is inserted into the groove 1021. The faceplate 13 is connected to the ferrule mount 12, wherein the faceplate 13 has a receptacle disposed opposite the ferrule 3.

It will be appreciated that, as shown in fig. 4, the closing plate 103, in addition to the closing grooves 1021, also plays a guiding role for the plug bush mounting seat 12 when the plug bush mounting seat 12 is mounted, thereby facilitating the mounting of the plug bush mounting seat 12.

In some examples, the sleeve mount 12 has a shaft aperture for passing the shaft 21 therethrough. When the plug bush mounting seat 12 is mounted, the closing plate 103 of the plug bush mounting seat 12 extends into the groove 1021, and simultaneously, the rotating shaft 21 extends into the rotating shaft through hole of the plug bush mounting seat 12.

In some examples, as shown in fig. 4 and 5, the conductive sheet assembly 2 is two, and when the two conductive sheets 22 are in the unfolded state, the two conductive sheets 22 are respectively located at two sides of the power taking portion 102.

Correspondingly, as shown in fig. 5, the socket part 101 has two elongated openings 1011, the power taking part 102 has two grooves 1021, and the openings of the two grooves 1021 face opposite directions, respectively, toward two sides of the power taking part 102. Both the two openings 1011 and the two grooves 1021 are centrally symmetrical about the central axis of the connection portion 111.

Also, the housing 1 has two closing plates 103 for closing the two grooves 102.

The conductive plates 22 in the two conductive plate assemblies 2 are respectively an N-pole conductive plate and an L-pole conductive plate, and the N-pole conductive plate and the L-pole conductive plate are respectively located at two sides of the power taking portion 102. In addition, the adapter body further has an E-pole conductive sheet, which may be a fixed conductive sheet, protruding from the power extracting portion 102 along a direction away from the socket portion 101.

Correspondingly, the plug bush 3 comprises an N-pole plug bush, an L-pole plug bush and an E-pole plug bush, wherein the N-pole plug bush is connected with the N-pole conducting strip, the L-pole plug bush is connected with the L-pole conducting strip, and the E-pole plug bush is connected with the E-pole conducting strip.

In some examples, as shown in fig. 6, the conductive sheet 22 includes a main body portion 221 and a bending portion 222, the bending portion 222 having a contact 220 and bending toward the power taking portion 102. In this way, when the conductive sheet 22 is unfolded relative to the power taking portion 102, the bending portion 222 can be parallel or approximately parallel to the track conductive sheet of the track, so as to increase the contact area between the contact 220 and the track conductive sheet, and improve the conductive stability.

Accordingly, as shown in fig. 6 and 7, the groove 1021 has a first groove portion 1021a and a second groove portion 1021b, the main body 221 is located in the first groove portion 1021a, the bending portion 222 is located in the second groove portion 1021b, and the depth of the second groove portion 1021b is greater than the depth of the first groove portion 1021 a.

In some examples, as shown in fig. 8, the closure plate 103 has a stiffener 1031. The reinforcing ribs 1031 can strengthen the strength of the closing plate 103.

The position of the stiffener 1031 is not limited in the embodiments of the present disclosure, and in some examples, as shown in fig. 9, the stiffener 1031 is located in the second groove portion 1021b.

In this way, since the second groove portion 1021b is deeper, it is more convenient to accommodate the reinforcing rib 1031, so that the width and height of the reinforcing rib 1031 can be larger, which is advantageous for improving the reinforcing effect of the reinforcing rib 1031.

In some examples, as shown in fig. 10, a portion of the groove 1021 near a corner of the conductive sheet 22 has a slot 1021c. The closing plate 103 has a plug piece 1032, and the plug piece 1032 is inserted into the slot 1021c.

Thus, the insertion slot 1021c can perform a limiting function on the insertion piece 1032, thereby performing a limiting function on the closing plate 103, preventing the closing plate 103 from being separated from the groove 1021.

To strengthen the structural strength of the base 11, in some examples, the connection portion 111 and the power taking portion 102 are integrally connected. In this way, the appearance integrity of the base 11 can also be improved, making the adapter more aesthetically pleasing.

In some examples, as shown in fig. 11, the connection 111 has a receiving cavity 1111, and the ferrule mount 12 is located inside the receiving cavity 1111. In this way, the receiving chamber 1111 can protect the plug bush mounting seat 12 and the plug bush 3. In addition, the plug bush mounting seat 12 is not exposed except the sealing plate 103, so that the integrity of the appearance of the adapter is better.

Of course, in other examples, the plug bush mounting seat 12 may have a receiving cavity, and the connection portion 111 is located inside the receiving cavity.

In some examples, as shown in fig. 3, the control member 4 includes a swivel rotatably connected to the connection 111, the panel 13, respectively. The side wall of the panel 13 and a part of the side wall of the connection portion 111 are embedded inside the turn.

When the spin ring rotates, the conductive sheet 22 can be controlled to be stored in or away from the power taking portion 102. In addition, the implementation manner of how the coil controls the expansion or storage of the conductive sheet 22 may be implemented by the adaptor in the related art, which is not described herein.

The disclosed embodiments provide for the exposed components of the adapter to be the panel 13, control 4, base 11, closure plate 103 and conductive sheet assembly 2 for a total of 5 components when the adapter is not inserted into the track. As shown in fig. 1, in the related art, the exposed parts of the adapter are the socket mount 12, the panel 13, the control member 4, the guide body 14, the guide protector 15, and the conductive sheet assembly 2, which are 6 pieces in total.

While the exposed parts of the adapter provided by the embodiments of the present disclosure are the control member 4, the panel 13 and the base 11, for a total of 3 parts, when the adapter is inserted into the track. In the related art, the exposed parts of the adapter are the plug bush mounting seat 12, the panel 13, the control member 4 and the guide protecting body 15, which are 5 parts in total.

It can be seen that, compared with the adapter in the related art, since the adapter provided by the embodiment of the disclosure does not need to split the base 11 (or called the electricity taking body 102) into the guide main body 14 and the guide protecting body 15, and the plug bush mounting seat 12 extends into the accommodating cavity 1111 of the base 11, the number of parts exposed by the adapter is smaller before and after the adapter is inserted into the track, which makes the appearance of the adapter have better integrity, makes the adapter more beautiful, and has fewer connection gaps and is not easy to damage.

To enable the adapter to be stably secured in the rail receptacle, in some examples, the adapter further includes an operating member 5 and a locking lever 6, as shown in fig. 11. The operating element 5 penetrates the side wall of the connecting portion 111 and is in driving connection with the locking lever 6. The lock lever 6 can be unfolded and stored with respect to the power taking section 12 under the control of the operating element 5.

When the locking lever 52 is unfolded relative to the power taking portion 102, the locking lever 52 can limit the power taking portion 102 in the track. When the lock lever 52 is stored in the power taking portion 102, the power taking portion 102 can be pulled out from the rail.

It should be noted that, the specific implementation manner of the operation member 5 for controlling the expansion and the storage of the locking rod 6 may be an implementation manner existing in the related art, which is not described herein again.

The disclosed embodiments also provide a track socket, as shown in fig. 12, which includes a track 01 and the above-described adapter 02.

The foregoing description of the preferred embodiments of the present utility model is not intended to be limiting, but rather, any modifications, equivalents, improvements, etc. that fall within the principles of the present utility model are intended to be included within the scope of the present utility model.
