Description

Technical Field

[0001] This utility model relates to the field of pins, specifically a quick-release pin. Background Technology

[0002] Currently, there are many connection points on the circuit board for connectors such as signal input (PWM), temperature and pressure sensors, 485 communication, and flow sensors, requiring a large number of pins. This makes the connectors unsuitable for small spaces and makes connection difficult. If soldering is used, it is very difficult to disassemble the PCB board after soldering.

[0003] Therefore, designing a pinout suitable for the aforementioned devices to connect the modules to the circuit board and facilitate disassembly is a problem that needs to be solved. Utility Model Content

[0004] Purpose of the utility model: To provide a quick-release pin to solve the above-mentioned problems existing in the prior art.

[0005] Technical solution: A quick-release pin, comprising:

[0006] A needle body consisting of a snap-fit ​​end, a bend section, and an electrical connection end, forming a continuous right-angle bend;

[0007] The snap-fit ​​end is provided with snap-fit ​​protrusions;

[0008] The snap-fit ​​protrusion abuts against the copper plating hole on the PCB board, and the snap-fit ​​end deforms into a predetermined shape when it abuts.

[0009] This invention features snap-fit ​​protrusions on the snap-fit ​​end, which allow for connection to the copper plating holes on the circuit board. During connection, the snap-fit ​​protrusions deform, and the stress from the deformation ensures stable contact between the protrusions and the copper plating holes. When disassembly is required, the PCB board can be easily removed.

[0010] It solves the problems of limited space, numerous connectors, and difficulty in placement.

[0011] It solves the disassembly and assembly problem, requiring no welding and allowing for simple disassembly.

[0012] To solve the installation and positioning problem, the design of the electrical connection guide section makes it easier for the copper plating hole to align with the snap-fit ​​end. Simply press it vertically downwards with the guide to complete the installation.

[0013] To solve the connection stability problem, the deformation force of the pin angle is used to lock the copper plating hole on the circuit board.

[0014] In a further embodiment, the snap-fit ​​end includes a snap-fit ​​transition section, a snap-fit ​​adapter section, and a snap-fit ​​guide section connected in sequence, and the size gradually decreases.

[0015] In a further embodiment, the top of the snap-fit ​​guide section is frustoconical. Designing the top of the snap-fit ​​guide section as frustoconical allows the snap-fit ​​end to connect better with the copper plating hole. During connection, the snap-fit ​​guide section provides guidance, facilitating the connection.

[0016] In a further embodiment, the electrical connection terminal includes an electrical connection transition section, an electrical connection adapter section, and an electrical connection guide section connected in sequence, with their dimensions gradually decreasing.

[0017] In a further embodiment, the top of the electrical connection guide segment is frustoconical.

[0018] The top of the electrical connection guide section is designed in a frustoconical shape to allow for better connection with adapters for connectors such as signal input (PWM), temperature and pressure sensors, 485 communication, and flow sensors.

[0019] In a further embodiment, one end of the turning segment is connected to the snap-fit ​​transition segment, and the other end is connected to the electrical connection transition segment. A transition surface is provided at the connection. By designing the transition surface, the resilience of the snap-fit ​​end, the turning segment, and the electrical connection end is increased.

[0020] Beneficial effects: This utility model discloses a quick-release pin. By designing a snap-fit ​​protrusion on the snap-fit ​​end, when connecting to the copper plating hole of the circuit board, the snap-fit ​​protrusion abuts against the copper plating hole to complete the connection. During connection, due to the design of the snap-fit ​​protrusion, the snap-fit ​​end deforms, and the stress of the deformation makes the snap-fit ​​protrusion stably abut against the copper plating hole. When disassembly is required, the PCB board can be pulled out. Attached Figure Description

[0028] This application relates to a quick-release pin, which will be explained in detail below through specific embodiments.

[0029] A quick-release pin includes:

[0030] A needle body consisting of a snap-fit ​​end 1, a bend section 2, and an electrical connection end 3, forming a continuous right-angle bend;

[0031] The snap-fit ​​end 1 is provided with snap-fit ​​protrusions 121;

[0032] The snap-fit ​​protrusion 121 abuts against the copper plating hole on the PCB board, and the snap-fit ​​end 1 deforms into a predetermined shape when abutting.

[0033] This utility model designs a snap-fit ​​protrusion 121 on the snap-fit ​​end 1, so that when connecting to the copper plating hole of the circuit board, the snap-fit ​​protrusion 121 abuts against the copper plating hole to complete the connection. During the connection, due to the design of the snap-fit ​​protrusion 121, the snap-fit ​​end 1 deforms, and the stress of the deformation makes the snap-fit ​​protrusion stably abut against the copper plating hole. When disassembly is required, the PCB board can be pulled out.

[0034] It solves the problems of limited space, numerous connectors, and difficulty in placement.

[0035] It solves the disassembly and assembly problem, requiring no welding and allowing for simple disassembly.

[0036] To solve the installation and positioning problem, the design of the electrical connection guide section 33 makes it easier for the copper plating hole to align with the snap-fit ​​end 1. Installation can be completed simply by pressing it vertically downwards with the guide.

[0037] To solve the connection stability problem, the deformation force of the pin angle is used to lock the copper plating hole on the circuit board.

[0038] The snap-fit ​​end 1 includes a snap-fit ​​transition section 11, a snap-fit ​​adapter section 12, and a snap-fit ​​guide section 13 connected in sequence, with their sizes gradually decreasing.

[0039] The top of the snap-fit ​​guide section 13 is truncated cone-shaped. Designing the top of the snap-fit ​​guide section 13 as truncated cone-shaped allows the snap-fit ​​end 1 to connect better with the copper plating hole. During connection, the snap-fit ​​guide section 13 provides guidance, making the connection easier.

[0040] The electrical connection terminal 3 includes an electrical connection transition section 31, an electrical connection adapter section 32, and an electrical connection guide section 33 connected in sequence, with their dimensions gradually decreasing.

[0041] The top of the electrical connection guide section 33 is frustoconical.

[0042] The top of the electrical connection guide section 33 is designed in a frustoconical shape to allow for better connection with adapters for connectors such as signal input (PWM), temperature and pressure sensors, 485 communication, and flow sensors.

[0043] One end of the transition section 2 is connected to the snap-fit ​​transition section 11, and the other end is connected to the electrical connection transition section 31. A transition surface is provided at the connection. By designing the transition surface, the rebound force of the snap-fit ​​end 1, the transition section 2, and the electrical connection end 3 is increased.

[0044] Working principle description: During operation, connect the electrical connection terminal 3 to the adapter of the fixed signal input (PWM), temperature and pressure sensor, 485 communication, flow sensor and other connectors;

[0045] After connection, align the copper plating hole of the PCB board with the snap-fit ​​end 1, and use the snap-fit ​​protrusion 121 to press against the copper plating hole to complete the connection. During connection, due to the design of the snap-fit ​​protrusion 121, the snap-fit ​​end 1 deforms, and the stress of the deformation makes the snap-fit ​​protrusion and the copper plating hole stably press against each other. When disassembly is required, simply pull out the PCB board.

[0046] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments.
