Description

Technical Field

[0001] This utility model relates to the field of electrical switch technology, and in particular to an anti-static toggle switch with a metal handle. Background Technology

[0002] A toggle switch is a manual control switch mainly used for controlling the on / off state of power circuits. It is characterized by its small size and ease of operation. A common toggle switch consists of a base, a handle extending from the base, and a handle sleeve that covers the handle. The circuit is switched on or off by moving the handle.

[0003] Currently, toggle switches used in small household appliances are increasingly favored by consumers for their handles, which now feature metal balls instead of the original handle sleeve. Because toggle switches are frequently operated, the handle is typically made of metal to prevent breakage. However, adding a metal ball to the handle creates a conductive connection between the ball and the handle. Static electricity generated when the ball comes into contact with the metal ball can damage the internal components of the toggle switch and even the small appliance itself. While covering the metal handle with soft plastic before installing the metal ball meets anti-static requirements, the metal ball is not securely fixed to the handle. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an antistatic toggle switch with a metal handle.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows: an anti-static toggle switch with a metal handle, comprising a switch base, a switch control element installed in the switch base, and a handle connected in the switch base to control the switching of the switch control element. The handle is made of metal and extends beyond the switch base. A plastic sleeve is fitted and fixed on the part of the handle extending beyond the switch base. An external thread is formed on the plastic sleeve. A metal handle head is screwed and fixed on the plastic sleeve. An internal thread corresponding to the external thread of the plastic sleeve is formed at the bottom of the metal handle head. The plastic sleeve isolates the metal handle head from the handle.

[0006] Preferably, the plastic tube sleeve is formed into an upper threaded section and a lower extension section. The upper threaded section is screwed to the metal handle head, and the lower extension section is further extended to be fixed to the handle sleeve.

[0007] Preferably, the portion of the handle extending beyond the switch base is formed as a stepped shaft, and the bottom of the plastic sleeve is formed with a stepped groove fitted onto the stepped shaft.

[0008] Preferably, the portion of the handle extending beyond the switch base is formed as an irregularly shaped shaft with an irregular end face, and the bottom of the plastic sleeve is formed as an irregularly shaped groove with an end face corresponding to the handle.

[0009] Preferably, the metal handle head is shaped like a ball.

[0010] Compared with existing technologies, this solution effectively fixes the metal handle head to the handle by setting an insulating plastic sleeve between the metal handle head and the metal handle, and directly screwing the metal handle head to the plastic sleeve. The plastic sleeve can also prevent static electricity from being transmitted to the whole machine through the handle, effectively meeting the requirements of electrostatic safety regulations.

[0014] The present invention will be further described below with reference to specific embodiments: Example 1

[0015] like Figure 1-3 As shown, this utility model discloses an anti-static toggle switch with a metal handle, comprising a switch base 1, a switch control element installed in the switch base 1, and a handle 2 connected to the switch base 1 to control the on / off state of the switch control element. To improve the durability of the handle 2, the handle 2 is made of metal, and a portion of the handle 2 extends beyond the switch base 1. A plastic sleeve 3 is fitted and fixed to the portion of the handle 2 extending beyond the switch base 1. The plastic sleeve 3 is made of rigid insulating material, injection molded, and is stable and reliable. A [missing information - likely a design element] is formed on the outside of the plastic sleeve 3. The metal handle head 4 is screwed and fixed to the plastic sleeve 3 via an external thread. In the current market, the metal handle head 4, which is becoming increasingly popular, is shaped like a ball. The bottom of the metal handle head 4 has an internal thread 41 corresponding to the external thread of the plastic sleeve 3. Compared with the soft plastic sleeve, which makes the connection between the metal handle head 4 and the handle 2 less secure, the plastic sleeve 3 can effectively fix the metal handle head 4 to the handle 2. The plastic sleeve 3 isolates the metal handle head 4 from the handle 2, which can prevent static electricity from being transmitted to the inside of the machine through the handle 2, effectively meeting the requirements of electrostatic safety regulations. Example 2

[0016] The difference from Embodiment 1 is that the plastic tube sleeve 3 is formed into an upper threaded section 31 and a lower extension section 32. The upper threaded section 31 is screwed to the metal handle head 4, and the lower extension section 32 is further extended to be fixed to the handle 2. While ensuring that the metal handle head 4 is firmly screwed to the upper threaded section 31 of the plastic tube sleeve 3, the lower extension section 32 of the plastic tube sleeve 3 is also firmly connected to the handle 2. Example 3

[0017] The difference from Embodiment 1 is that the part of the handle 2 extending out of the switch base 1 is formed as a stepped shaft 21, and the bottom of the plastic tube sleeve 3 is formed with a stepped groove 33 fitted on the stepped shaft 21. The fit between the stepped shaft 21, which is narrow at the top and wide at the bottom, and the stepped groove 33 allows the handle 2 to be inserted into the plastic tube sleeve 3 more accurately and conveniently, thus playing a pre-fitting role. Example 4

[0018] The difference from Embodiment 1 is that, in order to prevent the plastic sleeve 3 from rotating after being fitted onto the handle 2, the part of the handle 2 extending out of the switch base 1 is formed into an irregularly shaped shaft with an irregular end face, and the bottom of the plastic sleeve 3 is formed into an irregularly shaped groove with an end face corresponding to the handle 2.
