Description

Technical Field

[0001] The utility model belongs to the technical field of power modules, and particularly relates to an adaptive regulation power supply device for weak current engineering. Background Technique

[0002] A power module is a power supply that can be directly mounted on a printed circuit board. Its characteristic is that it can supply power to application-specific integrated circuits (ASICs), digital signal processors (DSPs), microprocessors, memories, field-programmable gate arrays (FPGAs), and other digital or analog loads.

[0003] The existing patent CN 218735599 U, an adaptive regulation PM power module, uses a limiting device to install the power module body inside the limiting device. Through the cooperation between the limiting device and the installation shell, power module bodies of different sizes can be installed. During the installation process of the power module body, through the limiting effect of the limiting plate, the power module body is clamped inside the limiting device. The limiting plate is driven by a lead screw. When the lead screw is driven to rotate by a motor, it will push the limiting plate to move. The limiting plate slides through the guidance of the guide rail, so that the power module body can be stably clamped and fixed. The automatic clamping control method has strong adaptability.

[0004] However, during the use of the existing patent, an adaptive regulation PM power module, the device drives the limiting plate to clamp the power module body through a lead screw transmission method. However, the lead screw transmission method is not convenient for accurately controlling the movement of the limiting plate, which makes it extremely easy for the limiting plate to damage the power module body. Content of the Utility Model

[0005] The purpose of the utility model is to provide an adaptive regulation power supply device for weak current engineering, which solves the problem that the aforementioned device drives the limiting plate to clamp the power module body through a lead screw transmission method, but the lead screw transmission method is not convenient for accurately controlling the movement of the limiting plate, which makes it extremely easy for the limiting plate to damage the power module body.

[0006] To achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0007] The utility model provides an adaptive adjustment power supply device for weak current engineering, which includes a power supply module and an installation device. The installation device includes an installation shell, a contact plate, a guide rod, a spring and a pulling component. Threaded holes are provided on both sides of the installation shell. The guide rod is slidably installed in the installation shell, penetrates through the installation shell and extends to the outside of the installation shell. The contact plate is fixedly installed on the guide rod. The spring is sleeved on the guide rod, and both ends of the spring are in contact with the inner wall of the installation shell and the contact plate respectively. The power supply module is located inside the installation shell, and the pulling component is installed on the contact plate.

[0008] Among them, the pulling component includes a cross bar and a pull rod. The cross bar is fixedly installed on the contact plate, penetrates through the installation shell and extends to the outside of the installation shell; the pull rod is fixedly installed on the cross bar and is located outside the installation shell.

[0009] Among them, the installation device further includes a contact pad, and the contact pad is fixedly installed on the contact plate.

[0010] Among them, the installation device further includes a support rod, and the support rod is fixedly installed inside the installation shell.

[0011] Among them, the installation device further includes heat dissipation fins, and the heat dissipation fins are fixedly installed on the outside of the installation shell.

[0012] When the adaptive adjustment power supply device for weak current engineering of the utility model is in use, pull the pull rods on both sides, so that the cross bars on both sides move in the opposite direction. The movement of the cross bars drives the contact plate fixedly connected thereto to move accordingly. At this time, the spring is gradually compressed under the pressing of the contact plate, and at this time the guide rod moves towards the outside of the installation shell. After the distance between the contact plates on both sides is opened, put the power supply module into the bottom of the installation shell and make it located between the contact plates on both sides. Then release the pull rods. At this time, the spring is no longer stressed, and the spring resets under the action of its own elastic force and pushes the contact plates on both sides to move towards each other to clamp the power supply module. After the clamping is completed, fix the installation shell on the circuit board through screws, thereby realizing the clamping installation of the power supply module, and driven by the elastic force of the spring, the power supply module will not be damaged.

[0018] In order to enable those skilled in the art to better understand the present utility model, the technical solution of the present utility model will be further described below in conjunction with the drawings and embodiments.

[0019] Embodiment 1:

[0020] As Figure 1-2 shown, Figure 1 It is a schematic overall structure diagram of an adaptive adjustment power supply device for a weak current project of the first embodiment of the present utility model, Figure 2 It is a schematic structural diagram of the installation device of the first embodiment of the present utility model.

[0021] The present utility model provides an adaptive adjustment power supply device for a weak current project: including a power module 101, and further including an installation device. The installation device includes an installation housing 102, a contact plate 103, a guide rod 104, a spring 105 and a pulling component. The pulling component includes a cross bar 107 and a pull rod 108. The installation device further includes a contact pad 109. The installation device further includes a support rod 110. By the foregoing solution, the problem that the foregoing device drives the limiting plate to clamp the power module body through a screw rod transmission method, but the screw rod transmission method is not convenient for precisely controlling the movement of the limiting plate, which makes the limiting plate extremely likely to damage the power module body is solved. It can be understood that this solution can also be used to solve the problem of enhancing the heat dissipation performance of the installation housing.

[0022] In this embodiment, the elastic force of the spring 105 is used to drive the contact plates 103 on both sides to clamp the power module 101, avoiding damage to the power module 101.

[0023] Among them, threaded holes 106 are provided on both sides of the installation housing 102. The guide rod 104 is slidably installed in the installation housing 102, penetrates through the installation housing 102, and extends to the outside of the installation housing 102. The contact plate 103 is fixedly installed on the guide rod 104. The spring 105 is sleeved on the guide rod 104. Both ends of the spring 105 are in contact with the inner wall of the installation housing 102 and the contact plate 103 respectively. The power supply module 101 is located in the installation housing 102. The pulling assembly is installed on the contact plate 103. The installation housing 102 has an inverted U-shaped structure with both sides protruding outward. The number of the contact plates 103 is two groups, and they are symmetrically distributed on both inner sides of the installation housing 102. Two groups of the guide rods 104 are symmetrically arranged above and below each group of the contact plates 103, and a group of the spring 105 is sleeved on each group of the guide rods 104. Through the arrangement of the threaded holes 106, it is convenient for the installation housing 102 to be fixed on the circuit board by screws. During use, the pulling assembly is used to pull the contact plates 103 on both sides to move in opposite directions, so that the spring 105 is compressed. After the power supply module 101 is placed between the contact plates 103 on both sides, the contact plates 103 are no longer pulled, so that the spring 105 drives the contact plates 103 to reset and clamp the power supply module 101, thus realizing the clamping installation of the power supply module 101. And driven by the elastic force of the spring 105, the power supply module 101 will not be damaged.

[0024] Secondly, the cross bar 107 is fixedly installed on the contact plate 103, penetrates through the installation housing 102, and extends to the outside of the installation housing 102; the pull rod 108 is fixedly installed on the cross bar 107 and is located outside the installation housing 102. The axes of the cross bar 107 and the pull rod 108 are perpendicular. Through the cooperation of the cross bar 107 and the pull rod 108, the contact plate 103 can be pulled.

[0025] Thirdly, the contact pads 109 are fixedly installed on the contact plates 103. The number of the contact pads 109 is two groups, and they are arranged on the opposite sides of the two groups of the contact plates 103. The contact pads 109 are made of sponge material, which can prevent the contact plates 103 from damaging the surface of the power supply module 101.

[0026] Finally, the support rod 110 is fixedly installed inside the installation housing 102. The number of the support rods 110 is multiple groups, and they are spaced apart and distributed on the inner top of the installation housing 102. When the power module 101 is placed inside the installation housing 102, the power module 101 contacts the support rod 110. The support rod 110 can keep the power module 101 in an overhead state inside the installation housing 102, thus facilitating the heat dissipation of the power module 101.

[0027] In this embodiment, during use, pull the pull rods 108 on both sides, so that the cross bars 107 on both sides move in the opposite direction. The movement of the cross bars 107 drives the contact plates 103 fixedly connected thereto to move accordingly. At this time, the spring 105 is gradually compressed under the pressing of the contact plate 103. At this time, the guide rod 104 moves towards the outside of the installation housing 102. After the distance between the contact plates 103 on both sides is opened, place the power module 101 from the bottom of the installation housing 102 and make it located between the contact plates 103 on both sides. Then release the pull rods 108. At this time, the spring 105 is no longer stressed. The spring 105 resets under the action of its own elastic force and pushes the contact plates 103 on both sides to move towards each other to clamp the power module 101. After the clamping is completed, fix the installation housing 102 on the circuit board through screws, thereby realizing the clamping installation of the power module 101, and driven by the elastic force of the spring 105, it will not damage the power module 101.

[0028] Embodiment Two:

[0029] As Figure 3 shown, where Figure 3 is the overall structural schematic diagram of an adaptive adjustment power supply device for a weak current project according to the second embodiment of the present invention. On the basis of the first embodiment, the adaptive adjustment power supply device for a weak current project in this embodiment further includes heat dissipation fins 201.

[0030] In this embodiment, through the arrangement of the heat dissipation fins 201, the heat dissipation performance of the installation housing 102 can be enhanced.

[0031] Among them, the heat dissipation fins 201 are fixedly installed on the outside of the installation housing 102. The upper end of the heat dissipation fins 201 is composed of multiple groups of spaced-apart support plates, which makes the heat dissipation area of the heat dissipation fins 201 extremely large. The heat dissipation fins 201 are made of aluminum alloy material, making it have excellent heat conduction performance. The heat generated by the power module 101 can be conducted to the heat dissipation fins 201 through the installation housing 102, and the heat is conducted to the outside through the heat dissipation fins 201, thereby being able to enhance the heat dissipation performance of the installation housing 102.

[0032] In this embodiment, the heat generated by the power supply module 101 can be conducted to the heat dissipation fins 201 through the installation housing 102, and the heat is conducted to the outside through the heat dissipation fins 201, so as to enhance the heat dissipation performance of the installation housing 102.

[0033] The above embodiments merely exemplarily illustrate the principles and effects of the present invention, rather than limiting the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
