Description

Technical Field

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

[0002] In some lighting fixture structures, the PIR needs to be fixed on the light-transmitting cover. Since the PIR is placed directly above the light panel, and traditional wiring harnesses are used for plugging and unplugging, the wiring harness fixing problem needs to be considered during assembly. Otherwise, when the light is turned on, the wiring harness will cast a shadow, affecting the customer's visual experience. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a new type of PCB board connection structure.

[0004] The technical solution adopted by this utility model to solve its technical problem is: A novel PCB board connection structure includes a first PCB board and a second PCB board. The first PCB board has a plurality of connection solder joints. A connecting seat is fixed on the second PCB board. One end of the connecting seat is provided with a number of spring pins corresponding to the number of connection solder joints. The tail end of the spring pin is connected to the second PCB board. When the first PCB board and the second PCB board are connected, the side of the second PCB board with the connecting seat presses against the first PCB board, and the front end of the spring pin presses on the corresponding connection solder joint and contracts under force.

[0005] Furthermore, the outer surface of the spring pin is provided with a gold plating layer.

[0006] Compared with the prior art, this utility model has the following advantages and effects: The structure is reasonably designed and easy to operate. At the same time, it maintains a good, reliable and effective electrical connection between PCB boards, which makes it possible to replace the traditional wire harness connection in specific narrow spaces (lighting fixture structure) and achieve the effect of quick and convenient disassembly and assembly. Attached Figure Description

[0007] Figure 1 This is a schematic diagram of the structure of an embodiment.

[0008] The accompanying drawings, which are provided to further illustrate this application and form part of this application, illustrate exemplary embodiments of this application and are used to explain this application, but do not constitute an undue limitation of this application. Detailed Implementation

[0009] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0010] Example

[0011] like Figure 1 As shown, the connection structure includes a first PCB board 1 and a second PCB board 2 that need to be connected. The first PCB board 1 has connection solder points 3 that need to be connected, and these solder points 3 are soldered onto the first PCB board 1. The second PCB board 2 has a connector 4 located on its back side. One end of the connector 4 has several spring pins 5, with the retractable ends of these spring pins 5 facing away from the back side of the second PCB board 2. The number of spring pins 5 corresponds one-to-one with the number of connection solder points 3. Specifically, when the first PCB board 1 and the second PCB board 2 need to be connected, the side of the second PCB board 2 with the connector 3 is pressed against the first PCB board 1. During this pressing process, the front ends of the spring pins 5 abut against the corresponding connection solder points 3, and the retractable ends retract under pressure. In specific environments, such as the confined space inside a lamp, the environmental structure will continuously exert force on the first PCB board 1 and the second PCB board 2.

[0012] In this embodiment, the outer surface of the spring pin 5 is provided with a gold-plated layer. The gold-plated layer stabilizes the contact resistance at 5-10mΩ, effectively reducing signal attenuation, providing excellent impedance matching, and ensuring high-frequency signal fidelity.

[0013] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
