When the guide rail meter is assembled, the plurality of circuit boards are mainly installed in the accommodating cavity, and each circuit board is provided with a specific position in the accommodating cavity, so that each circuit board needs to be positioned and connected respectively in the assembling process, and the guide rail meter has low production efficiency due to long time consumption under the condition of more circuit boards.

In view of the above problems, an embodiment of the present application provides a guide rail table, as shown in fig. 1, fig. 2 and fig. 3, and fig. 1 is a schematic diagram of an overall structure of the guide rail table according to the embodiment of the present application. Fig. 2 is a schematic diagram of an internal structure of a guide rail table according to an embodiment of the present application. Fig. 3 is an exploded view of an internal structure of a guide rail table according to an embodiment of the present application.

Referring to fig. 1, 2 and 3, the guide rail meter includes a housing 100, a first circuit board 200 and a second circuit board 300; the housing 100 has a receiving cavity; the first circuit board 200 is disposed in the accommodating cavity and connected with the housing 100; the second circuit board 300 is disposed in the accommodating cavity and connected to the first circuit board 200.

One or more first circuit boards 200 and one or more second circuit boards 300 may be disposed, and the relative positions between the first circuit boards 200 and/or the second circuit boards 300 may be arbitrarily set. When there are a plurality of first circuit boards 200, each first circuit board 200 is connected to the housing 100, and the second circuit board 300 may be connected to any one of the first circuit boards 200.

Further, the connection between the first circuit board 200 and the housing 100 may be a direct connection or an indirect connection, and the connection of the second circuit board 300 and the first circuit board 200 may be a direct connection or an indirect connection. For example, in some possible manners, when one first circuit board 200 is provided and a plurality of second circuit boards 300 are provided, the plurality of second circuit boards 300 are connected to each other, and only one of the second circuit boards 300 is connected to the first circuit board 200, thereby relatively fixing the first circuit board 200 to the plurality of second circuit boards 300, and integrating them.

The housing 100 may be formed of two or more parts, and the different parts may be detachably connected to each other, so that when the parts in the accommodating cavity are assembled, the different parts of the housing 100 may be detached, and after the parts are assembled in the accommodating cavity, the different parts of the housing 100 are fixedly connected to each other, so that the housing 100 integrally forms a relatively closed shell-like part.

In the above-described scheme, although the second circuit board 300 is not directly connected to the housing 100, the second circuit board 300 is fixed in the housing 100 through the first circuit board 200, so there is a relatively fixed position between the housing 100, the first circuit board 200, and the second circuit board 300.

In the manufacturing process of the guide rail meter, the first circuit board 200 and the second circuit board 300 may be connected in advance, for example, the first circuit board 200 and the second circuit board 300 may be connected in advance in other factories or other production lines. When the guide rail meter is assembled, the whole body formed by the second circuit board 300 and the first circuit board 200 is arranged in the accommodating cavity, and the first circuit board 200 is connected with the shell 100, so that the second circuit board 300 is not required to be connected with the shell 100, the assembly flow of the guide rail meter is simplified, and the production efficiency of the guide rail meter is improved.

There are various ways in which the first circuit board 200 is connected to the housing 100.

As shown in fig. 2 and 3, in some embodiments, the guide rail meter further includes a support post 400 and a screw member 500, the support post 400 is provided on an inner wall of the housing 100, an end of the support post 400 abuts on the first circuit board 200, and the screw member 500 is screw-coupled with the support post 400 through the first circuit board 200.

The strut 400 is a columnar part, and the strut 400 may be integrally formed with the housing 100, or may be connected to the housing 100 in other manners, which is not limited by the fixing manner of the strut 400 and the housing 100 in the embodiment of the present application.

The number of the pillars 400 may be one or more, for example, in order to improve the positional stability of the first circuit board 200, at least three pillars 400 may be provided, and the plurality of pillars 400 are non-linearly arranged and respectively connected with the first circuit board 200 through screws 500. And in order to reduce the influence of the support post 400 on the circuit arrangement on the first circuit board 200, the abutment position of the support post 400 with the first circuit board 200 may be provided at the edges or four corners of the first circuit board 200.

In order to facilitate the connection of the screw 500 to the support column 400, the end of the support column 400 may be prefabricated with a screw hole, and the corresponding first circuit board 200 may be provided with a through hole, where the screw 500 is a bolt, a screw, or the like, and the screw 500 is screwed with the screw hole at the end of the support column 400 after passing through the through hole on the first circuit board 200.

The end of the post 400 may not be prefabricated with a screw hole, and in this case, the screw member 500 may be a self-tapping screw, which is threaded on the post 400 after passing through a through hole in the first circuit board 200, and simultaneously is screwed with the post 400.

The support column 400 can be used not only to connect the first circuit board 200, but also to position the first circuit board 200 at the end of the support column 400 so that the first circuit board 200 can be fixed in the receiving chamber without being attached to the inner wall of the housing 100.

There may be various connection methods between the second circuit board 300 and the first circuit board 200.

Illustratively, in some embodiments, the second circuit board 300 is connected to the first circuit board 200 by pins 600.

The two ends of the pin 600 are inserted into the first circuit board 200 and the second circuit board 300, respectively, so that the first circuit board 200 and the second circuit board 300 can be connected, and the assembly of the first circuit board 200 and the second circuit board 300 is more convenient.

Alternatively, the first circuit board 200 and the second circuit board 300 may be provided with pads 700, and the pins 600 are inserted on the pads 700. Because the thickness of the spacer 700 is greater, the portion into which the pin 600 is inserted is longer, so that the connection between the first circuit board 200 and the second circuit board 300 through the pin 600 is more stable, and the first circuit board 200 and the second circuit board 300 do not relatively shake.

In addition, the contact pin 600 may serve as a conductive medium between the first circuit board 200 and the second circuit board 300 to electrically connect the first circuit board 200 and the second circuit board 300 while mechanically connecting the first circuit board 200 and the second circuit board 300.

Referring to fig. 1, 2 and 3, in some embodiments, the housing 100 includes a bottom case 110 and a cover case 120 that are fastened together along a first direction X, the second circuit board 300 includes a bottom circuit board 320 and a cover circuit board 310, and the cover circuit board 310, the first circuit board 200 and the bottom circuit board 320 are disposed in sequence along the first direction; the support column 400 is disposed on the inner wall of the bottom case 110, and the support column 400 extends along the first direction X to abut against the first circuit board 200.

Since the bottom case 110 and the cover case 120 are fastened relatively along the first direction X, after the bottom case 110 and the cover case 120 are disassembled, the opening of the bottom case 110 faces the first direction X, and the cover circuit board 310, the first circuit board 200, and the bottom circuit board 320 are sequentially disposed along the first direction X, so that the bottom circuit board 320, the first circuit board 200, and the cover circuit board 310 are conveniently installed into the opening of the bottom case 110 along the first direction X during the assembly process.

The support column 400 extends along the first direction, and it can be seen that when the end surface of the support column 400 abutting against the first circuit board 200 faces the first direction X and the cover circuit board 310, the first circuit board 200, and the bottom circuit board 320 are placed from the opening of the bottom case 110 along the first direction, the end surface of the support column 400 can function to position the plurality of circuit boards in the first direction X.

When the guide rail table is assembled, the cover shell 120 can be removed from the bottom shell 110, the whole body formed by the bottom layer circuit board 320, the first circuit board 200 and the cover layer circuit board 310 is placed into the bottom shell 110 along the first direction, then the first circuit board 200 is connected with the support column 400 on the bottom shell 110, and the fixing of the three circuit boards on the bottom shell 110 can be realized at the same time, and finally the cover shell 120 is buckled on the bottom shell 110 along the first direction. The whole assembly process has fewer steps, and the production efficiency of the guide rail meter is further improved.

Referring to fig. 2 and 3, in some embodiments, a guiding notch 321 is formed on the bottom circuit board 320, and the supporting post 400 passes through the guiding notch 321, and a side wall of the guiding notch 321 contacts with a side wall of the supporting post 400.

The side wall of the guiding notch 321 may be partially contacted with the side wall of the support post 400, or may be contacted with the side wall of the support post 400 by the circumference, which is not limited in the embodiment of the present application. For example, the support 400 is cylindrical, and the guiding notch 321 may be a circular notch matched with the support 400 or a square notch, and the inner wall of the square notch is tangent to the side wall of the support 400.

In the process of assembling the whole of the bottom circuit board 320, the first circuit board 200 and the cover circuit board 310 into the housing 100, the guide notch 321 on the bottom circuit board 320 may be sleeved on the support 400, and then the whole of the bottom circuit board 320, the first circuit board 200 and the cover circuit board 310 may be installed into the bottom case 110 along the extending direction of the support 400 until the first circuit board 200 contacts with the end of the support 400 to be positioned.

In this process, the lateral wall of the guiding notch 321 contacts with the lateral wall of the pillar 400, thereby playing a guiding role, facilitating the rapid positioning of each circuit board in the above assembly process, and further improving the assembly efficiency of the guide rail meter.

In some embodiments, the bottom case 110 is further provided with a positioning protrusion 111, the bottom circuit board 320 is provided with a positioning hole 322, and the positioning protrusion 111 is disposed through the positioning hole 322 along the first direction.

The positioning protrusion 111 is a protrusion structure provided on the inner wall of the bottom chassis 110, and the positioning hole 322 is a hole structure provided on the bottom circuit board 320, which may be a through hole or a blind hole.

The position of the positioning protrusion 111 in the bottom case 110 corresponds to the position of the positioning hole 322 in the bottom case 110, and the shapes and the sizes of the positioning protrusion 111 and the positioning hole 322 are not limited, so long as the positioning protrusion 111 can be penetrated into the positioning hole 322 after the bottom circuit board 320 is mounted, and thus the position of the bottom circuit board 320 is limited by the positioning protrusion 111 and is relatively unchanged or can be changed only in a small range after the bottom circuit board 320 is mounted in the bottom case 110.

Therefore, the positioning hole 322 on the bottom circuit board 320 is matched with the positioning protrusion 111 on the bottom shell 110, so that the positioning between the bottom circuit board 320 and the bottom shell 110 is realized, the positioning between the first circuit board 200 and the support column 400 is indirectly realized, and the connection of the first circuit board 200 and the support column 400 at a specific position is facilitated.

In actual use of the guide rail meter, when the bottom circuit board 320 needs to be stressed during use, at this time, the position of the bottom circuit board 320 is fixed only by the connection of the bottom circuit board 320 and the first circuit board 200, which may have a problem of insufficient strength.

In view of the above, referring to fig. 3, in some embodiments, a positioning table 112 is further disposed on the bottom case 110, and a surface of the positioning table 112 facing the cover 120 abuts against the bottom circuit board 320.

The positioning table 112 may be disposed on the bottom wall of the bottom case 110 (the wall of the bottom case 110 away from the cover case 120) or may be disposed on the side wall of the bottom case 110 (the wall surrounding the bottom wall of the bottom case 110), which is not limited in the embodiment of the present application.

In the assembly process of the guide rail meter, when the bottom circuit board 320 contacts with the surface of the positioning table 112 facing the cover shell 120, it is explained that the whole body formed by the bottom circuit board 320, the first circuit board 200 and the cover layer circuit board is assembled in place in the first direction X, so that positioning among different parts in the assembly process of the guide rail meter is facilitated, and the assembly efficiency of the guide rail meter is improved.

In the use of the guide rail meter, although the bottom circuit board 320 is not directly connected with the bottom shell 110, the position of the bottom circuit board 320 in the bottom shell 110 can be reinforced by the abutting connection of the positioning table 112, so that the bottom circuit board 320 is prevented from shaking or moving in the accommodating cavity after being stressed, and the stability of the electrical performance of the guide rail meter is improved.

In order to further fix the bottom circuit board 320 in the case that one side surface of the bottom circuit board 320 abuts against the surface of the positioning table 112, as shown in fig. 2 and 3, in some embodiments, a pressing buckle 113 is further disposed on a side wall of the bottom case 110, and a surface of the pressing buckle 113 facing away from the cover case 120 abuts against the bottom circuit board 320.

Both sides of the bottom circuit board 320 are respectively abutted against the positioning table 112 and the press buckle 113, so that shaking in the first direction is not easy to occur.

The press buckle 113 is a protruding structure disposed on a side wall of the bottom case 110, and may be made of a non-metal material with high elasticity, such as a plastic member, a rubber member, or the like, or may be integrally formed with the bottom case 110 by using the same material.

In the process of loading the bottom circuit board 320 into the bottom case 110, the bottom circuit board 320 is placed into the bottom case 110 along the first direction X, and when the bottom circuit board 320 contacts the press button 113, the bottom circuit board 320 and the press button 113 are pressed against each other, so that the bottom circuit board 320 is slightly bent, or the press button 113 is slightly deformed, until the bottom circuit board 320 is loaded into the side of the press button 113 facing away from the cover case 120.

Alternatively, referring to fig. 3, the surface of the press button 113 facing the cover case 120 may be provided with a slope that gradually slopes away from the cover case 120 in a direction away from the sidewall of the press button 113, so as to provide a guide for loading the bottom circuit board 320 into the side of the press button 113 facing away from the cover case 120.

The press buttons 113 may be disposed on one side wall of the bottom case 110, or may be disposed on opposite side walls of the bottom case 110, which is not limited in the embodiment of the present application.

Referring to fig. 2 and 3, in some embodiments, ribs 114 are disposed on an inner wall of the bottom case 110, fool-proof notches 323 are disposed on the bottom circuit board 320, and the ribs 114 are at least partially located in the fool-proof notches 323.

When the bottom circuit board 320 is mounted, the bottom circuit board 320 can be mounted in the bottom case 110 only when being matched with the ribs 114, so that an operator is prevented from reversely mounting the bottom circuit board 320.

Fig. 4 is a schematic diagram of an internal structure of another guide rail table according to an embodiment of the present application. Referring to fig. 4, in some embodiments, a socket 800 is disposed on the bottom circuit board 320, a socket 900 is disposed on a first side wall of the bottom case 110, a socket end of the socket 800 is exposed to the socket 900, the bottom circuit board 320 abuts against a second side wall of the bottom case 110, and the second side wall is opposite to the first side wall.

Wherein the first side wall and the second side wall are relatively structures with the same socket 900 as a reference object, and when different socket 900 are used as a reference object, the first side wall and the second side wall are different.

For example, when two power strip 800 are disposed on the bottom circuit board 320, two sockets 900 are disposed on the corresponding sidewalls of the bottom case 110, and a first sidewall using one socket 900 as a reference may be used as a second sidewall when another socket 900 is used as a reference.

When a user connects with the plug-in terminal of the power strip 800 through the socket 900, the power strip 800 can receive thrust towards the inner side of the first side wall, at this time, because the bottom layer circuit board 320 is abutted with the second side wall of the bottom shell 110, the bottom layer circuit board 320 is not easy to move in the shell 100 after receiving the thrust, the installation position of the bottom layer circuit board 320 is more stable, the stability of the electric signal of the bottom layer circuit board 320 is improved, and the user can conveniently operate the patch.

In summary, in the embodiment of the present application, the second circuit board 300 is connected to the first circuit board 200, so that when the guide rail meter is assembled, the whole body formed by the second circuit board 300 and the first circuit board 200 is installed into the accommodating cavity, and only the first circuit board 200 is required to be connected to the housing 100, and the second circuit board 300 is not required to be connected to the housing 100, thereby simplifying the assembly process of the guide rail meter and improving the production efficiency of the guide rail meter.
