Description

Technical Field

[0001] This utility model relates to the field of electronic connection device technology, specifically a trapezoidal connection point device for aluminum substrate. Background Technology

[0002] Aluminum-based copper-clad laminates are metal-based boards whose core function is to support electronic components and efficiently dissipate heat. They use an aluminum alloy substrate with an insulating layer and a copper foil circuit layer on the surface. The high thermal conductivity of the metal substrate allows for rapid heat dissipation from the components, ensuring stable circuit operation. They are widely used in high-temperature environments such as LED lighting, automotive electronics, and power supply equipment. They reduce product size, extend component lifespan, and also provide excellent electromagnetic shielding and mechanical strength, meeting the heat dissipation and structural requirements of complex electronic devices.

[0003] The existing Chinese utility model patent with publication number CN206379548U discloses a connector for a single-sided contact aluminum substrate. This connector includes an integrally injection-molded connector housing. At least two terminal receiving slots are arranged side-by-side within the connector housing. Each terminal receiving slot contains a single-sided contact terminal. The tail of each single-sided contact terminal has a piercing terminal spike, and the head of each single-sided contact terminal has a contact-type bullet piece on the same side. A plastic contact block integrally injection-molded with the connector housing is provided between adjacent terminal receiving slots. At least two transverse wire insertion holes are arranged side-by-side at the tail of the connector housing, aligning laterally with the piercing terminal spikes. The tail of the connector housing also has piercing slots for the piercing terminal spikes. A guide plate for guiding insertion is provided on the inner side of the connector housing. This utility model uses lower-cost materials, does not cause excessive temperature rise in the wires, and makes wire use safer and without potential hazards.

[0004] Currently, the trapezoidal connection point devices for aluminum substrates still have the following problems: Currently, the common aluminum substrate connections on the market consist of fracture lines composed of multiple small holes, and the mechanical strength of the connection depends on the substrate that is not completely severed. During panel transport, insertion, or soldering, even slight external forces (such as collisions or compression) can cause premature breakage of the circuit board. Furthermore, when the circuit board separates from the panel through the small holes, the fracture process may create stress concentration around the holes, especially for precision components near the "stamp" holes (such as BGA packages, small capacitors, and resistors), potentially causing hidden damage. Additionally, the fractured edges may be uneven, requiring additional milling or grinding, increasing process costs. If not addressed, uneven edges may affect subsequent assembly (e.g., preventing a tight fit when embedded in a housing) or cause scratches when plugging or unplugging connectors. Utility Model Content

[0005] The purpose of this invention is to provide a trapezoidal connection point device for aluminum substrates to solve the problem of poor separation effect of aluminum substrates during assembly of plug-in components as mentioned in the background art.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: The present invention provides a trapezoidal connection point device for aluminum substrate, comprising an aluminum substrate body, a connecting frame, a clamping side frame, a block groove and a side groove. The clamping side frame is located between the aluminum substrate bodies, and triangular connecting frames are installed at the four vertices of the aluminum substrate body. Square side grooves are opened on both sides of the clamping side frame, and the block groove is opened on both sides of the aluminum substrate body. The connecting frame includes movable blocks 1 that are elastically installed at both ends, and block grooves 2 are provided on both sides of the movable blocks 1. A frame bottom groove is provided at the bottom of the connecting frame. A telescopic rod is movably installed inside the frame bottom groove, and the bottom end of the telescopic rod is fixedly connected to the frame plate.

[0007] Preferably, the aluminum substrate body is composed of multiple segments forming a circular structure, and the aluminum substrate body is assembled by a movable block and a connecting frame on one side.

[0008] Preferably, cylinders are elastically installed on both sides of the inner side of the first block groove, and one end of the cylinder is movably installed inside the second block groove.

[0009] Preferably, the gap between the aluminum substrate body and the clamping side frame is trapezoidal, and the movable block on one side is installed inside the side groove of the clamping side frame.

[0010] Preferably, a bottom plate is fixedly installed at the bottom of the card frame plate, and the bottom plate and the connecting frame have the same width.

[0011] Preferably, the card frame plate is movably connected to the connecting frame via a telescopic rod, and the surface of the connecting frame can be provided with a plate groove.

[0012] Preferably, the apex of the connecting frame is arc-shaped, and the clamping side frame is located in the middle of one side of the connecting frame.

[0013] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects: 1. When the aluminum substrate is assembled, a trapezoidal gap is left between the main body of the aluminum substrate and the clamping side frame bracket. The trapezoidal micro-connection point has a larger contact area with the circuit board, which can provide stronger mechanical connection force compared with other shapes of connection points. Moreover, the shape of the trapezoidal micro-connection point is relatively simple. In the process of circuit board manufacturing, it can be molded in one piece without the need for other processing steps, which can improve production efficiency, reduce production costs, and after the end chip is placed, it can be easily broken off by hand. In addition, due to the design of the "trapezoidal" micro-connection point, the waste area of ​​connection is wide and the product connection area is narrow. After the board is separated, the burrs will be concentrated on the process edge and will not be left on the product, resulting in a smooth cut edge. 2. When the aluminum substrate is assembled, the main body of the aluminum substrate is elastically installed inside the slot through the movable block one, so that the main body of the aluminum substrate and the connecting frame are spliced ​​together. The installation and disassembly are convenient, and the splicing can be completed through the slot without complicated tools. This can greatly improve the assembly effect and reduce the difficulty of operation. After the slots are spliced, they interlock with each other to form a stable connection, making the entire equipment assembly reliable. Attached Figure Description
