Technical Field

The utility model relates to the technical field of circuit board assemblies, in particular to a fixing piece and a circuit board assembly.

Background

In electronic devices (e.g., in-vehicle display devices, notebook computers), circuit board assemblies are very critical components, and generally include a circuit board and a terminal provided on one side of the circuit board. Wherein the circuit board can provide a stable circuit environment. The terminal may be used to communicate with an electronic component.

In order to ensure stable connection between the wiring terminal and the circuit board, the circuit board assembly generally further comprises a fixing piece, and the fixing piece is arranged on one side of the circuit board, which is close to the wiring terminal. The fixing piece is partially abutted against one side, far away from the circuit board, of the wiring terminal, so that the wiring terminal can be effectively prevented from falling off from the circuit board.

However, due to manufacturing tolerances of the terminals, the fixing member fixed to the circuit board cannot effectively abut against the terminals. For example, when the actual size of the terminal is small, a gap exists between the position where the fixing member abuts against the terminal, the terminal cannot abut against the terminal, and the terminal is easily detached from the circuit board.

In the description of the present specification, a particular feature, structure, material, or characteristic may be combined in any suitable manner in one or more embodiments or examples.

With the increasing development of the technology level, more and more electronic devices are presented in our daily lives, such as vehicle-mounted display devices, calculators, and notebook computers.

The circuit board assembly is a critical component in an electronic device, and in an embodiment of the present application, as shown in fig. 1, fig. 1 is a schematic diagram of the circuit board assembly provided in the embodiment of the present application, and the circuit board assembly 100 may include a circuit board 1 and a connection terminal 2. It should be understood that the circuit board assembly 100 provided in the embodiment of the present application may be applied to a vehicle-mounted display device, a calculator, a notebook computer, or the like, and is not limited herein.

The circuit board 1 can provide a stable circuit environment. The circuit board 1 may be a printed circuit board, which is also called a printed wiring board, is an important electronic component, is a support for electronic components, and is a carrier for electrical connection of the electronic components.

The connection terminal 2 is located at one side of the circuit board 1 and is connected with the circuit board 1. The terminal 2 may be used to communicate with an electronic component.

Since the circuit board 1 can provide a stable circuit environment, the electronic components can reliably and stably operate after being communicated with the circuit board 1 through the wiring terminal 2.

In order to ensure stable connection between the connection terminal 2 and the circuit board 1, with continued reference to fig. 1, the circuit board assembly 100 provided in the embodiment of the present application may further include a fixing member 3, where the fixing member 3 is located on a side of the circuit board 1 near the connection terminal 2, and is connected to the circuit board 1, and the fixing member 3 abuts against the connection terminal 2.

As shown in fig. 2, fig. 2 is a schematic view of a fixing member 3 according to an embodiment of the present application, where the fixing member 3 in the circuit board assembly 100 according to an embodiment of the present application may include a main body portion 31 and an abutment portion 32. The body portion 31 may be used for connection with the circuit board 1 (fig. 1). The abutment portion 32 is connected to the main body portion 31. Thus, the fixing member 3 is mounted on the side of the circuit board 1 close to the connection terminal 2 by the connection of the main body 31.

The abutment portion 32 has elasticity, can be used to abut against the terminal 2 (fig. 1), and can be deformed. The contact portion 32 is located on the side of the terminal 2 away from the circuit board 1, and abuts against the terminal 2.

Since the abutting portion 32 has elasticity, the abutting portion 32 can abut against the terminal 2 by being deformed after the fixing member 3 is mounted on the circuit board 1. Like this, the butt portion 32 in the mounting 3 can absorb the manufacturing tolerance of binding post 2 through producing deformation, and effectual butt joint terminal 2 to make mounting 3 can play the fastening effect to binding post 2, effectively avoided binding post 2 to drop from circuit board 1.

In addition, under the condition that a certain manufacturing tolerance exists in the wiring terminal 2, the fixing piece 3 can still abut against the wiring terminal 2, so that the wiring terminal 2 and the fixing piece 3 do not need to achieve higher manufacturing precision in manufacturing, and the manufacturing difficulty and the mass production difficulty of the wiring terminal 2 and the fixing piece 3 are reduced.

The number of the abutment portions 32 may be set to one or a plurality, and may be set specifically according to actual needs, and is not particularly limited herein.

In some embodiments, with continued reference to fig. 2, the body portion 31 may include a top plate 311 and side plates 312. The side plate 312 is located on the top plate 311 side, and one end is connected to the top plate 311 and the other end is connected to the circuit board 1 (fig. 1).

The connection terminal 2 may be disposed on a side of the top plate 311 near the side plate 312. At this time, the top plate 311 and the side plate 312 of the main body 31 can play a certain role in protecting the terminal 2, so that the terminal 2 can be prevented from being accidentally knocked.

The angle between the side plate 312 and the top plate 311 is not particularly limited herein, and as illustrated in fig. 2, the side plate 312 is exemplarily disposed perpendicular to the top plate 311.

The number of the side plates 312 is not particularly limited herein, and as illustrated in fig. 2, the number of the side plates 312 may be set to three, and three side plates 312 may be disposed at the left, right, and rear sides below the top plate 311, respectively.

Of course, as shown in fig. 3, fig. 3 is one of schematic views of a fixing member 3 according to another embodiment of the present application, the number of side plates 312 may be two, and two side plates 312 are disposed on the left and right sides below the top plate 311, respectively.

With continued reference to fig. 3, the abutment 32 is located on a side of the top plate 311 adjacent to the side plate 312, and is connected to the top plate 311 or the side plate 312. In the direction perpendicular to the top plate 311, a space is provided between the abutting portion 32 and one end of the side plate 312 remote from the top plate 311.

In this way, at least a part of the terminal 2 can be disposed within the above-described space, so that the abutting portion 32 can abut against the terminal 2, thereby enabling the terminal 2 to be fastened.

It is to be understood that the connection position of the abutting portion 32 and the main body portion 31 is not particularly limited herein, as long as there is a space between the abutting portion 32 and one end of the side plate 312 away from the top plate 311. Illustratively, as shown in fig. 3, the abutment 32 is connected to the side plate 312.

The connection manner of the abutment portion 32 and the main body portion 31 may be specifically set according to practical situations, and the abutment portion 32 may be integrally formed with the main body portion 31. At this time, the abutting portion 32 and the main body portion 31 may be integrally formed by a sheet metal process.

Of course, in other embodiments, the main body 31 may include only the side plate 312, and the abutment portion 32 is located at one side of the side plate 312 and connected to the side plate 312. One end of the side plate 312 may be used for connection with the circuit board 1. The abutting portion 32 and one end of the side plate 312 close to the circuit board 1 have a space therebetween.

In this case, at least a part of the connection terminal 2 may be provided in a space between the abutting portion 32 and one end of the side plate 312 near the circuit board 1, and the abutting portion 32 may also exert a tightening effect on the connection terminal 2.

Since the main body 31 includes only the side plate 312, the main body 31 is simple in structure and low in manufacturing cost.

In some embodiments, as shown in fig. 4, fig. 4 is a schematic diagram of a second embodiment of the fixing member 3, in which the abutment portion 32 is disposed obliquely, and has a fixed end (i.e. the left end of the abutment portion 32 in fig. 4) and an abutting end (i.e. the right end of the abutment portion 32 in fig. 4). The fixed end is connected with the top plate 311 or the side plate 312. The abutting end is located on the side of the fixed end away from the top plate 311 in the direction perpendicular to the top plate 311.

In this way, since the abutting portion 32 is provided obliquely, and in the direction perpendicular to the top plate 311, the abutting end is located on the side of the fixed end away from the top plate 311, with a gap between the abutting end and the top plate 311. When the abutting end abuts against the wiring terminal 2, the abutting end is easier to deform towards the direction close to the top plate 311, so that the fixing piece 3 is more convenient to use.

Of course, in other embodiments, the abutment portion 32 is connected to the side plate 312, and the abutment portion 32 is disposed parallel to the top plate 311.

At this time, when the degree of inclination of the abutting portion 32 is different, different positions of the surface of the abutting portion 32 on the side close to the circuit board 1 can abut against the surface of the terminal 2 on the side away from the circuit board 1, so that the effect of fastening the terminal 2 can be played.

With continued reference to fig. 4, in some embodiments, the abutment 32 may be a sheet-like structure, and the abutment 32 of the sheet-like structure may be less difficult to manufacture.

Meanwhile, after the abutting part 32 deforms, and when one side surface is attached to the wiring terminal 2, the stress area between the abutting part 32 and the wiring terminal 2 is large, so that the pressing force applied to the wiring terminal 2 by the abutting part 32 is larger, and the fastening effect is better.

Of course, in other embodiments, the abutment 32 may also be a block-like structure. At this time, the abutting portion 32 has a large structural strength, and is more reliable in use.

As shown in fig. 2, in some embodiments, the fixing member 3 may further include a connection portion 33, where the connection portion 33 is located on a side of the top plate 311 away from the side plate 312 and is connected to the top plate 311. The connection portion 33 is for connection with the connection terminal 2 (fig. 1).

Like this, mounting 3 not only can fasten binding post 2 through butt portion 32, can also fasten binding post 2 through connecting portion 33 to make mounting 3 can fasten a plurality of binding posts 2, improved the practicality of mounting 3 greatly.

The connection method between the connection portion 33 and the top plate 311 is not particularly limited, and the connection portion 33 and the top plate 311 are illustratively integrally formed.

The connection manner of the connection portion 33 and the connection terminal 2 is not particularly limited herein, and the connection portion 33 may be connected to the connection terminal 2 by a bolt, for example. At this time, the connecting portion 33 is provided with a screw hole, and the connection terminal 2 is also provided with a screw hole. Thus, the bolt is inserted into the screw hole of the connecting portion 33 and the screw hole of the terminal 2, so that the connecting portion 33 and the terminal 2 can be connected together.

With continued reference to fig. 2, in some embodiments, the side plate 312 is provided with a relief hole 3121, and the relief hole 3121 extends through an end of the side plate 312 remote from the top plate 311. One end of the abutting portion 32 is connected to the wall of the relief hole 3121.

In this way, since the terminals 2 on both sides of the side plate 312 can pass through the side plate 312 of the main body 31 through the avoidance hole 3121, and the abutting portion 32 is disposed at the avoidance hole 3121, according to practical situations, the fixing member 3 can not only abut against the terminal 2 on one side of the side plate 312, but also abut against the terminal 2 on the other side of the side plate 312, thereby improving the convenience in use of the fixing member 3.

The placement position of the abutment portion 32 on the side plate 312 may be specifically set according to the actual situation, and as illustrated in fig. 2, the abutment portion 32 is disposed on the left side of the side plate 312 by way of example. At this time, the abutting portion 32 can abut against the terminal 2 located on the left side of the side plate 312, and can fasten the terminal 2 located on the left side of the side plate 312.

Moreover, when the abutting portion 32 needs to abut against the connection terminal 2 on the right side of the side plate 312, as shown in fig. 5, fig. 5 is a partial schematic view of the circuit board assembly 100 according to the embodiment of the present application, and a portion of the connection terminal 2 on the right side of the side plate 312 may penetrate to the left side of the side plate 312 on the right side of the top plate through the avoidance hole 3121. In this way, the abutting portion 32 located on the left side of the side plate 312 can abut against a part of the terminal 2 extending to the left side of the side plate 312, and can also fasten the terminal 2 on the right side of the side plate 312.

Of course, in other embodiments, the side plate 312 may not have the avoidance hole 3121. At this time, it is understood that when the abutting portion 32 is connected to the surface of the side plate 312 side, the abutting portion 32 can only abut against the terminal 2 of the side plate 312 side close to the abutting portion 32 side.

Because the side plate 312 is not provided with the avoiding hole 3121, the structural strength of the side plate 312 is relatively high, so that the fixing member 3 is more reliable in use.

To facilitate the mounting of the fixing member 3 on the circuit board 1, in some embodiments, a clamping hole is formed on a surface of the circuit board 1 near one side of the fixing member 3. As shown in fig. 2, the fixing member 3 may further include a clamping portion 34, where the clamping portion 34 is connected to an end of the side plate 312 away from the top plate 311, and is configured to be inserted into a clamping hole (not shown in fig. 1) of the circuit board 1 to be clamped with the circuit board 1.

Like this, because joint portion 34 wears to locate the downthehole joint that can carry out the joint with circuit board 1 of joint, curb plate 312 just can be in the same place with circuit board 1 through joint portion 34 in the form of joint, and it is more convenient to connect between curb plate 312 and the circuit board 1 to effectively improved the production efficiency of circuit board assembly 100.

Of course, in other embodiments, the side plate 312 of the fixing member 3 may be connected to the circuit board 1 by other connection methods, and the side plate 312 is connected to the circuit board 1 by bolts.

In some embodiments, as shown in fig. 6, fig. 6 is a partial enlarged view at a in fig. 2, the clamping portion 34 may include a first clamping portion 341 and a second clamping portion 342. The first engagement portion 341 is connected to an end of the side plate 312 remote from the top plate 311 (fig. 5). The second clamping portion 342 is connected to one end of the first clamping portion 341 away from the side plate 312, and along the first direction, the second clamping portion 342 is located at one side of the first clamping portion 341. Wherein the first direction is parallel to the top plate 311.

The first clamping portion 341 of the clamping portion 34 may penetrate the circuit board 1 through a clamping hole on the circuit board 1. Because the second clamping portion 342 is connected with one end of the first clamping portion 341 away from the side plate 312, and along the first direction, the second clamping portion 342 is located at one side of the first clamping portion 341, after the first clamping portion 341 passes through the circuit board 1, the second clamping portion 342 can extend into one side of the circuit board 1 away from the wiring terminal 2 through the clamping hole, so that the second clamping portion 342 can abut against the surface of the circuit board 1 away from the wiring terminal 2, and further the clamping portion 34 can be prevented from being separated from the clamping hole, so that the clamping portion 34 can be clamped with the circuit board 1.

Of course, in other embodiments, the clamping portion 34 may further include only the second clamping portion 342, where the second clamping portion 342 is connected to an end of the side plate 312 away from the top plate 311, and the second clamping portion 342 is located on one side of the side plate 312 along the first direction. Wherein the first direction is parallel to the top plate 311. Thus, the side plate 312 can be inserted into the fastening hole, and the second fastening portion 342 can extend into the side of the circuit board 1 away from the terminal 2 and abut against the surface of the circuit board 1 away from the terminal 2, so that the side plate 312 can be fastened with the circuit board 1 through the fastening portion 34.

With continued reference to fig. 6, in some embodiments, a surface of the second clamping portion 342 adjacent to a side of the top plate 311 (fig. 5) is a bevel 3421. The distance between the end of the inclined surface 3421, which is close to the first clamping portion 341, and the top plate 311 is smaller than the distance between the end of the inclined surface 3421, which is far from the first clamping portion 341, and the top plate 311. The engagement portion 34 has ductility.

It should be noted that, after the clamping portion 34 penetrates the circuit board 1 through the clamping hole on the circuit board 1, a portion of the inclined surface 3421 on the second clamping portion 342 is located in the clamping hole, and an included angle between the inclined surface 3421 and a surface of the circuit board 1 on a side far away from the connection terminal 2 is an acute angle. At least a portion of the vertical projection of the second clamping portion 342 on the surface of the circuit board 1 on the side away from the connection terminal 2 is located outside the clamping hole.

Therefore, when the main body 31 needs to be assembled on the circuit board 1, after the user stretches into the circuit board 1 away from the terminal 2 through the clamping part Kong Jiangka, the second clamping part 342 is provided with the inclined surface 3421 on the side close to the top plate 311, and the inclined surface 3421 on the second clamping part 342 can effectively ensure that the second clamping part 342 abuts against the surface of the circuit board 1 away from the terminal 2, so that the clamping fit between the clamping part 34 and the circuit board 1 is firmer.

In some embodiments, the clip portion 34 is malleable. Thus, when the clamping portion 34 is required to be clamped with the circuit board 1, the clamping portion 34 can be first inserted into the clamping hole. At this time, the vertical projection of the engaging portion 34 on the surface of the circuit board 1 on the side away from the terminal 2 is located inside the engaging hole.

Then, the user may rotate the second clamping portion 342 by 45 degrees using the ductility of the clamping portion 34, so that the relative position between the second clamping portion 342 and the first clamping portion 341 is changed.

In this way, since the second clamping portion 342 has the inclined surface 3421 on the side close to the top plate 311, the inclined surface 3421 can be tightly abutted against the surface of the circuit board 1 on the side far away from the connecting terminal 2 after the relative position between the inclined surface 3421 and the first clamping portion 341 is changed, so that the clamping portion 34 and the circuit board 1 can not shake along the axial direction of the clamping hole after being clamped together.

Of course, in other embodiments, the surface of the second clamping portion 342 near the side of the top plate 311 is a plane, and the plane is parallel to the top plate 311. In a state where the clamping portion 34 is clamped to the circuit board 1, the plane is parallel to the surface of the circuit board 1 on the side away from the connection terminal 2, and at least a portion of the vertical projection of the second clamping portion 342 on the surface of the circuit board 1 on the side away from the connection terminal 2 is located outside the clamping hole.

In this way, after the clamping portion 34 is clamped with the circuit board 1, the contact area between the surface of the second clamping portion 342, which is close to the top plate 311, and the circuit board 1 is larger, so that the clamping between the clamping portion 34 and the circuit board 1 is more reliable.

The foregoing is merely illustrative of the present utility model, and the present utility model is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
