Description

Technical Field

[0001] The utility model relates to the field of circuit boards, and more specifically, to a printed circuit board. Background Art

[0002] Printed circuit board is a plate-shaped electronic product made using electronic printing technology. As a carrier and connector of electronic components, it plays a vital role in electronic equipment.

[0003] Several electronic components and a power interface are fixed on an existing printed circuit board, and one end of the power interface is generally exposed at the outer edge of the circuit board. After the circuit board is installed in the housing, the power interface needs to extend into the groove of the housing, thereby ensuring that the user can easily access it without disassembling the device or opening the housing. However, because one end of the power interface is exposed at the outer edge of the circuit board, the power interface is easily bumped during the process of moving the circuit board, thereby risking separation from the circuit board.

[0004] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a printed circuit board.

[0006] The above technical purpose of the utility model is achieved through the following technical scheme: a printed circuit board, including a board body and a power interface, the board body is provided with four mounting holes, the four mounting holes are respectively arranged near the four corners of the board body, the board body is detachably connected with a rigid sleeve, the rigid sleeve surrounds the part of the power interface exposed from the board body, and there is a gap between the outer peripheral wall of the power interface and the inner wall of the rigid sleeve.

[0007] The utility model is further configured as follows: the rigid sleeve is fixed on the plate body by screws.

[0008] The utility model is further configured as follows: clamping blocks are fixedly connected to both sides of the rigid sleeve, and the clamping blocks include an upper clamping plate and a lower clamping plate, and the upper clamping plate and the lower clamping plate are used together to clamp the plate body.

[0009] The utility model is further configured as follows: a through hole is provided on the upper clamping plate, a through hole is provided on the plate body, a threaded hole is provided on the side of the lower clamping plate facing the upper clamping plate, and the screw passes through the through hole and the through hole and is threadedly connected with the threaded hole.

[0010] The utility model is further configured as follows: the plate body is provided with four through holes, the four through holes are distributed in pairs on both sides of the power interface, and the aperture of the through holes is equal to the aperture of the mounting hole.

[0011] The utility model is further configured as follows: two positioning strips are arranged on one side of the plate body, and the spacing between the two positioning strips is equal to the sum of the widths of a rigid sleeve and two clamping blocks.

[0012] To sum up, the utility model has the following beneficial effects: during the transportation of the board body, the rigid cover can protect the power interface, so that the force of the collision is borne by the rigid cover, thereby ensuring that the power interface is not easily separated from the board body, and there is a gap between the outer wall of the power interface and the inner wall of the rigid cover, and the setting of the gap provides a certain buffer distance for the collision deformation of the rigid cover, thereby further ensuring the safety of the power interface, and after the board body is transported and quality inspected, when the board body needs to be installed in the product, people can remove the rigid cover, so that the rigid cover will not affect the installation of the board body.

[0018] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] Printed circuit boards, such as Figure 1 and Figure 2As shown, it includes a board body 1 and a power interface 2. Four mounting holes 3 are opened on the board body 1, and the four mounting holes 3 are respectively arranged near the four corners of the board body 1. A rigid sleeve 4 is detachably connected to the board body 1, and the rigid sleeve 4 surrounds the part of the power interface 2 exposed from the board body 1. After people weld the power interface 2 on the board body 1, the rigid sleeve 4 is installed on the board body 1, and the rigid sleeve 4 surrounds the part of the power interface 2 exposed from the board body 1, so that during the transportation of the board body 1, the rigid sleeve 4 can protect the power interface 2, so that the force generated by the collision is borne by the rigid sleeve 4, thereby ensuring that the power interface 2 is not easily separated from the board body 1, and there is a gap between the outer peripheral wall of the power interface 2 and the inner wall of the rigid sleeve 4. The setting of the gap provides a certain buffer distance for the collision deformation of the rigid sleeve 4, thereby further ensuring the safety of the power interface 2. After the board body 1 is transported and the quality inspection is completed, when the board body 1 needs to be installed in the product, people can remove the rigid sleeve 4, so that the rigid sleeve 4 will not affect the installation of the board body 1.

[0020] like Figure 1 , Figure 3 and Figure 4 As shown, the rigid sleeve 4 is fixed to the plate body 1 by screws. On the one hand, the screws are convenient to disassemble and install, thereby facilitating the detachable connection of the rigid sleeve 4. On the other hand, the screws have high fixing strength, so that when a collision occurs, the position of the rigid sleeve 4 is not easily offset. Both sides of the rigid sleeve 4 are fixedly connected with clamping blocks 5, and the clamping blocks 5 include an upper clamping plate 6 and a lower clamping plate 7. The upper clamping plate 6 and the lower clamping plate 7 are used to clamp the plate body 1 together. The distance between the upper clamping plate 6 and the lower clamping plate 7 is equal to the thickness of the plate body 1. The rigid sleeve 4 can be pre-fixed by clamping the upper clamping plate 6 and the lower clamping plate 7, so that people can feel comfortable. When we use screws to fix the rigid sleeve 4, the rigid sleeve 4 is not easy to shake. A through hole 8 is opened on the upper clamping plate 6, a through hole 9 is opened on the plate body 1, and a threaded hole 10 is opened on the side of the lower clamping plate 7 facing the upper clamping plate 6. The screw passes through the through hole 8 and the through hole 9 and is threadedly connected with the threaded hole 10. After the clamping block 5 clamps the plate body 1, the through hole 8 and the through hole 9 are aligned. After the screw passes through the through hole 8 and the through hole 9 together, it is directly threadedly connected with the threaded hole 10, thereby realizing the fixation of the two clamping blocks 5. Since the rigid sleeve 4 is fixedly connected to the clamping block 5, the fixation of the rigid sleeve 4 is realized. This arrangement prevents the screw from damaging the structure of the plate body 1.

[0021] like Figure 3 and Figure 4As shown, the plate body 1 has four through holes 9, which are distributed in pairs on both sides of the power interface 2. The aperture of the through hole 9 is equal to the aperture of the mounting hole 3. The upper clamping plate 6 has two through holes 8, which correspond to the number of the through holes 9 and the mounting holes 3, so that after people remove the rigid sleeve 4, the removed four screws can be used for the installation of the plate body 1, so that people do not need to prepare additional screws for installing the plate body 1. Two positioning strips 11 are provided on one side of the plate body 1, and the spacing between the two positioning strips 11 is equal to the sum of the widths of a rigid sleeve 4 and two clamping blocks 5. When people install the rigid sleeve 4, they put the two clamping blocks 5 back to each other. One side of the clamp 5 respectively contacts with the two positioning strips 11, and the two positioning strips 11 play a guiding role in the installation of the rigid sleeve 4, and at the same time ensure that the positions of the through holes 8 and the perforations 9 in the width direction of the plate body 1 are not easily offset, which is convenient for people to install. The clamp block 5 also includes a connecting block connecting the upper clamp plate 6 and the lower clamp plate 7. When the two clamp blocks 5 contact the positioning strips 11 and move, the upper clamp block 5 and the lower clamp block 5 respectively contact the upper and lower sides of the plate body 1 until the connecting block contacts the plate body 1, and all the through holes 8 and the corresponding perforations 9 are aligned. This arrangement makes it easy to install the rigid sleeve 4 after the clamp block 5 slides to the limit position.

[0022] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
