Description

Technical Field

[0001] This utility model belongs to the field of PCB board technology, and specifically relates to a PCB board mounting structure. Background Technology

[0002] Printed circuit boards (PCBs) are widely used in various fields and have become an indispensable part of various electronic products. Currently, PCB mounting structures are basically separate installation structures, meaning there is a one-to-one correspondence between the PCB and the mounting structure. This design presents the following technical problems:

[0003] Because PCBs vary in length, product interchangeability is poor. For example, when a PCB is damaged, the lengths of PCBs supplied by different manufacturers may differ significantly. Therefore, the mounting structure that accompanies the PCB must also be replaced, resulting in higher maintenance costs in the later stages.

[0004] Furthermore, to eliminate the effects of static electricity, PCB board mounting structures are generally equipped with static elimination mechanisms. However, due to the different mounting structures of PSB boards, the static elimination mechanisms are not entirely the same. As a result, operators may not be familiar with all the static elimination mechanisms, making it impossible to properly perform static elimination before installing the PCB board. At the same time, even if operators are familiar with the common static elimination mechanisms, they may easily forget to perform static elimination during actual operation. Utility Model Content

[0005] This invention addresses the problem of poor interchangeability in existing PCB mounting structures, which leads to high maintenance and replacement costs for PCBs. It provides a PCB mounting structure that is suitable for mounting PCBs of different lengths, so that replacing a PCB does not require replacing the entire mounting structure due to inconsistent PCB lengths, thereby minimizing the cost of PCB maintenance.

[0006] To solve the technical problem, the technical solution adopted by this utility model is as follows:

[0007] A PCB board mounting structure is characterized by comprising an L-shaped connecting joint, a connecting plate inserted between two symmetrically arranged connecting joints, a PCB board placement slot on the connecting joint, and a PCB board placement slot corresponding to the PCB board placement slot on the connecting joint on the connecting plate. Each connecting joint is provided with a set of elastic tabs for clamping the PCB board. At least three insertion holes for inserting an electrostatic elimination structure are provided on the side end face of the connecting joint away from the connecting plate. The insertion holes extend into the connecting joint along the direction toward the connecting plate. At least one of the insertion holes is equipped with an elastic locking pin for locking the insertion pin of the electrostatic elimination structure. At least three elastic locking tongues are connected below the connecting joint to match the mounting holes on the mounting slot plate.

[0008] In some embodiments, the lower end of the resilient latch is pointed, and a step is provided above the resilient latch for engaging with a mounting hole in the mounting slot plate.

[0009] In some embodiments, the connector is further provided with a locking hole, the locking hole is provided with a locking pin, and the locking pin is adapted to the bending groove on the mounting plate.

[0010] In some embodiments, at least two of the insertion holes have different longitudinal cross-sectional shapes.

[0011] In some embodiments, the connector has a plug on the side facing the connector plate, and the connector plate has a slot that is arranged along the length of the connector plate and passes through the connector plate.

[0012] In some embodiments, the slot has a convex cross-sectional shape, and the plug has a convex cross-sectional shape.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This utility model discloses a PCB board mounting structure, including an L-shaped connecting joint. A connecting plate is inserted between two symmetrically arranged connecting joints. Each connecting joint has a PCB board placement slot, and the connecting plate has corresponding PCB board placement slots. Each connecting joint has a set of elastic tabs for clamping the PCB board. At least three insertion holes for inserting an electrostatic elimination structure are formed on the side of the connecting joint facing away from the connecting plate. These insertion holes extend into the connecting joint along the direction towards the connecting plate. At least one insertion hole contains an elastic locking pin for locking the insertion pin of the electrostatic elimination structure. At least three elastic locking tongues are connected to the bottom of the connecting joint to mate with the mounting holes on the mounting plate. In use, the connecting joints and connecting plates are connected by a plug-in connection. The connecting plate can be connected between the two connecting joints using the plug on the connecting joint and the slot on the connecting plate. When the length of the PCB board is flexible, a connecting plate of appropriate length can be selected to connect between the two connecting joints, or the length of the connecting plate can be cut to meet the PCB board mounting requirements. Therefore, it is not necessary to replace the entire PCB board mounting structure, thereby reducing replacement and maintenance costs.

[0015] This invention features insertion holes on the outer end face of the connector, allowing the insertion pins of the static elimination structure to be inserted into the connector. This enables the static elimination structure to be directly installed at both ends of the connector. During PCB board installation, static electricity from the human body first contacts the static elimination structures at both ends of the connector, thus removing it and preventing it from being transferred to the PCB board. Compared to existing technologies, this invention allows for direct insertion of the static elimination structure into the insertion holes of the connector. Furthermore, since the PCB board needs to be pressed into the PCB board placement slot during installation, the hands naturally use both ends of the connector as support points. Therefore, when installing the PCB board, the hands naturally come into contact with the static elimination structures at both ends of the connector, automatically eliminating static electricity from the human body. Even if the worker forgets to perform static elimination during PCB board installation, the static elimination devices at both ends of the connector can automatically eliminate static electricity, ensuring the safety of PCB board installation.

[0023] The present invention will be further described below with reference to the embodiments. The described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of the present invention.

[0024] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model; the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance; furthermore, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "joined" should be interpreted broadly, for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0025] Referring to the accompanying drawings, the PCB board mounting structure of this utility model includes an L-shaped connecting joint 1, with a connecting plate 2 inserted between two symmetrically arranged connecting joints 1. A PCB board placement slot 11 is provided on the connecting joint 1, and a PCB board placement slot 11 corresponding to the PCB board placement slot 11 on the connecting plate 2 is provided on the connecting plate 2. Each connecting joint 1 is provided with a set of elastic pieces 12 for clamping the PCB board. At least three insertion holes 13 for inserting an electrostatic elimination structure are provided on the side end face of the connecting joint 1 away from the connecting plate 2. The insertion holes 13 extend into the connecting joint 1 along the direction towards the connecting plate 2. At least one of the insertion holes 13 is equipped with an elastic locking pin 15 for locking the insertion pin of the electrostatic elimination structure. At least three elastic locking tongues 16 are connected below the connecting joint 1 to be adapted to the mounting holes 011 on the mounting slot plate 01.

[0026] The principle of static elimination structure is understood by those skilled in the art. The static elimination structure is made of conductive material. When the worker's hand comes into contact with the static elimination structure, the static elimination structure can automatically remove the static electricity from the human body, thereby eliminating the impact of human static electricity on the PCB board.

[0027] In some embodiments, the lower end of the elastic locking tongue 16 is pointed, and a step 161 for engaging with the mounting hole 011 on the mounting slot plate 01 is provided above the elastic locking tongue 16. In specific implementation, since the connecting joint 1 is mounted on the mounting slot plate 01, this utility model can directly utilize multiple (at least three) elastic locking tongues 16 to engage with the mounting holes 011 on the mounting slot plate 01. Since the mounting holes 011 on the mounting slot plate 01 are generally arranged side-by-side, at least three elastic locking tongues 16 on the connecting joint 1 are also arranged side-by-side below the connecting joint 1.

[0028] In some embodiments, the connecting joint 1 is further provided with a locking hole 14, and the locking hole 14 is equipped with a locking pin, which is adapted to the bending groove 012 on the mounting plate 01. This allows the connecting joint 1 and the mounting plate 01 to be locked using the elastic locking tongue 16, while the cooperation between the locking pin and the bending groove 012 can improve the tightness of the connection between the connecting joint 1 and the mounting plate 01.

[0029] In the specific implementation process, in order to increase its own structural strength and reduce the weight of the mounting groove plate 01, the mounting groove plate 01 is generally bent multiple times. Therefore, the present utility model directly utilizes the bending groove 012 formed by bending on the mounting groove plate 01 to cooperate with the locking pin to increase the connection tightness between the connection joint 1 and the mounting groove plate 01. At the same time, it is not necessary to improve the structure of the mounting groove plate 01, and the existing mounting groove plate 01 can be directly utilized.

[0030] In some embodiments, there are at least two insertion holes 13, and the longitudinal cross-sectional shapes of the insertion holes 13 are different. On the one hand, the insertion holes 13 with different cross-sectional shapes are used to prevent the electrostatic elimination structure from being inserted incorrectly, so that each insertion hole 13 can correspond to the insertion pins of the electrostatic elimination structure one by one. On the other hand, the insertion holes 13 with different cross-sections can also be used to improve the connection tightness with the electrostatic elimination structure.

[0031] In the specific implementation process, the cross-section of some insertion holes 13 is circular, the cross-section of some insertion holes 13 is rectangular, and the cross-section of some insertion holes 13 is triangular. Therefore, the multiple insertion holes 13 can be composed of rectangular insertion holes, triangular insertion holes, circular insertion holes, regular polygon insertion holes, etc.

[0032] Among them, the depth of each insertion hole 13 should also be adapted to the length of the insertion pin of the electrostatic elimination structure. Those skilled in the art can understand and comprehend this, and it will not be elaborated here.

[0033] In some embodiments, a plug is provided on one side of the connection joint 1 facing the connection plate 2, and a slot 21 is provided on the connection plate 2 along the length direction of the connection plate 2 and penetrating through the connection plate 2. By using the mutual cooperation of the plug and the slot 21, the connection plate 2 can be connected between two connection joints 1. When the length of the PCB board is conveniently changed, a connection plate with a suitable length can be selected to be connected between the two connection joints, or the length of the connection plate can be cut to meet the installation of the PCB board. Therefore, it is not necessary to replace the entire PCB board installation structure, thereby reducing the cost of replacement and maintenance.

[0034] In some embodiments, the cross-sectional shape of the slot 21 is "convex" - shaped, and the cross-sectional shape of the plug is "convex" - shaped. Among them, after the convex - shaped slot 21 and the convex - shaped plug are inserted, they have the characteristics of firm connection and good structural strength, and can meet the installation and use requirements of the PCB board.

[0035] In summary, this utility model uses a plug-in connection between the connector and the connecting plate during use. The connecting plate is connected between two connectors simply by using the plug on the connector and the slot on the connecting plate. When the length of the PCB board can be varied, a connecting plate of appropriate length can be selected to connect between the two connectors, or the length of the connecting plate can be cut to fit the PCB board installation. Therefore, it is not necessary to replace the entire PCB board mounting structure, thus reducing replacement and maintenance costs.

[0036] This invention features insertion holes on the outer end face of the connector, allowing the insertion pins of the static elimination structure to be inserted into the connector. This enables the static elimination structure to be directly installed at both ends of the connector. During PCB board installation, static electricity from the human body first contacts the static elimination structures at both ends of the connector, thus removing it and preventing it from being transferred to the PCB board. Compared to existing technologies, this invention allows for direct insertion of the static elimination structure into the insertion holes of the connector. Furthermore, since the PCB board needs to be pressed into the PCB board placement slot during installation, the hands naturally use both ends of the connector as support points. Therefore, when installing the PCB board, the hands naturally come into contact with the static elimination structures at both ends of the connector, automatically eliminating static electricity from the human body. Even if the worker forgets to perform static elimination during PCB board installation, the static elimination devices at both ends of the connector can automatically eliminate static electricity, ensuring the safety of PCB board installation.
