Description

Technical Field

[0001] This utility model belongs to the field of switches, and in particular relates to a metal push button switch. Background Technology

[0002] Metal push-button switches are widely used in industrial automated production lines for controlling the start and stop of production equipment. The structure of a traditional metal push-button switch includes: a base and a metal housing outside the base; a PCB board inside the base; a tactile switch on the PCB board; a button for pressing the tactile switch at the top of the metal housing; a socket at the bottom of the base; and a set of pins inside the socket, with the upper ends of the pins soldered to the PCB board. The disadvantage is that the socket is only fixed by the solder joints between the pins and the PCB board, resulting in poor connection strength. When plugs are inserted or removed, the pins are easily deformed or broken. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a metal push-button switch with better socket connection strength.

[0004] To solve the above problems, the technical solution adopted by this utility model includes: a base and a metal shell outside the base, a PCB board inside the base, a tactile switch on the PCB board, a button for pressing the tactile switch on the upper end of the metal shell, a socket at the bottom of the base, a set of pins inside the socket, the upper end of the pins being soldered to the PCB board, a protective plate integrally formed at the lower end of the base, and the protective plate having a set of spaced conical guide grooves, a riveting hole at the bottom of the socket smoothly transitioning with the conical guide grooves, the upper end of the pins passing through the conical guide grooves and riveting to the riveting hole, and then being soldered to the PCB board.

[0005] The base has an upper support platform, a lower support platform, a left support platform, a right support platform, and a middle support platform at its bottom that support the PCB board.

[0006] The base has positioning plates on both sides at its lower end, and the socket is located between the positioning plates.

[0007] The socket is fitted with a plug, and the plug contains a set of spring pins that are connected to the pins.

[0008] The pin is cylindrical.

[0009] The socket has guide grooves on both sides, and the plug has guide ribs on both sides that cooperate with the guide grooves.

The lower end of the button is provided with an upper pressing post embedded in the positioning groove.

[0011] The metal casing is equipped with a nut and an O-ring.

[0012] The advantages of the metal push button switch of this utility model are as follows: after the socket pins are riveted to the base, they are soldered to the PCB board. At the same time, the protective plate also plays a role in positioning the socket and preventing the pins from being pushed forward and deformed, thereby greatly improving the connection strength.

[0013] The present invention will be further described below with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation

[0015] Reference Figure 1-6 As shown, the metal push button switch of this utility model includes a base 1 and a metal housing 2 disposed outside the base 1. A PCB board 3 is disposed inside the base 1, and a tactile switch 4 is disposed on the PCB board 3. A button 5 for pressing the tactile switch 4 is disposed on the upper end of the metal housing 2. A socket 6 is disposed at the bottom of the base 1, and a set of pins 7 is disposed inside the socket 6. The upper ends of the pins 7 are soldered to the PCB board 3. A protective plate 8 is integrally formed at the lower end of the base 1, and the protective plate 8 has a set of spaced conical guide grooves 9. The bottom of the socket 6 has riveting holes 10 that smoothly transition with the conical guide grooves 9. The upper ends of the pins 7 pass through the conical guide grooves 9 and are riveted to the riveting holes 10, and then soldered to the PCB board 3.

[0016] Preferably, the base 1 has an upper support platform 11, a lower support platform 12, a left support platform 13, a right support platform 14, and a middle support platform 15 at its bottom, which support the PCB board 3. This allows the PCB board 3 to be more stably mounted at the bottom of the base 1, thereby improving stability.

[0017] Preferably, positioning plates 16 are provided on both sides of the lower end of the base 1, and the socket 6 is disposed between the positioning plates 16. This is to prevent the socket 6 from shifting left or right, thereby further improving the connection strength.
