Technical Field

[0001] The utility model relates to the technical field of detection switches, in particular to a high-head and high-travel detection switch. Background Art

[0002] A travel switch is a commonly used low-current main control electrical appliance that uses the collision of mechanical moving parts to move its contacts to connect or disconnect the control circuit to achieve a certain control purpose. Usually, this type of switch is used to limit the position or stroke of mechanical movement, so that the moving machine can automatically stop, reverse, change speed or automatically reciprocate at a certain position or stroke;

[0003] During use, the detection switch is connected with other circuit components to detect the parameters of the components or circuits. However, the current detection switches still expose some problems when used. The conventional detection switches have a short stroke when used, which causes abnormal false touches when the switch is used, affecting the detection accuracy. In view of the problems exposed during the use of the current detection switches, it is necessary to structurally improve and optimize the stroke of the detection switch. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a high-head and high-stroke detection switch, which has the characteristics of effectively increasing the detection switch stroke, avoiding abnormal false touches, and improving detection accuracy.

The contact piece is fixed on the stabilizing block, and the two groups of contact pieces are integrally connected, and the end of the contact piece is bent upward and formed with a bending head.

[0008] As an optimal technical solution for a high-head and high-stroke detection switch of the utility model, a groove for accommodating a pressure spring is provided at the bottom end of the limit seat, a sinking groove is provided inside the base, and a positioning column is provided in the sinking groove to prevent the pressure spring from sliding.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0010] In the technical solution, the rubber cover is locked on the base by the bending part and the protruding part to maintain stability, and the rubber head is guided by the rubber cover to rise or fall inside the base.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example

[0021] like Figure 1-4 As shown, a high-head and high-stroke detection switch disclosed by the utility model includes a base 1, a storage cavity is opened downward on the upper surface of the base 1, two groups of terminals 2 are arranged horizontally and in parallel inside the storage cavity, and the two ends of the terminals 2 pass through the two sides of the base 1, and a rubber cover 3 is embedded at the top of the base 1, and the rubber cover 3 is locked and connected to the base 1 through a locking assembly. A rubber head 4 is vertically penetrated in the rubber cover 3, and a pressure spring 5 is embedded at the bottom end of the rubber head 4, and the pressure spring 5 is kept stable by the internal positioning assembly of the base 1. Contact pieces 43 are symmetrically provided on the outer side of the bottom end of the rubber head 4. When the contact pieces 43 are pressed down, they contact the terminals 2 and make the circuit connected. In this technical solution, the stroke of the detection switch is effectively increased to facilitate the good operation of the detection switch.

[0022] Specifically, the locking assembly includes a protrusion 11 symmetrically integrally formed on the outer wall of the base 1, and a bent portion 31 integrally formed at both ends of the rubber cover 3. A locking groove 32 is provided in the bent portion 31. The rubber cover 3 and the base 1 are connected by the engagement of the bent portion 31 and the protrusion 11. In this embodiment, the U-shaped structure formed by the two bent portions 31 facilitates the locking of the rubber cover 3 on the base 1.

[0023] Specifically, a limiting seat 41 is integrally formed at the bottom end of the rubber head 4, and stabilizing blocks 42 are symmetrically arranged on both sides of the lower end of the limiting seat 41. The contact pieces 43 are fixed on the stabilizing blocks 42, and the two groups of contact pieces 43 are integrally connected. The ends of the contact pieces 43 are bent upward and formed with bending heads 44. In this embodiment, the bending heads 44 are arc-shaped structures, which effectively prevent the contact pieces 43 from getting stuck on the terminals 2 when moving up and down.

[0024] Specifically, the bottom end of the limit seat 41 is provided with a groove for accommodating the pressure spring 5, and the interior of the base 1 is provided with a sinking groove 12, and the sinking groove 12 is provided with a positioning column 13 for preventing the pressure spring 5 from sliding. In this embodiment, the sinking groove 12 and the positioning column 13 can effectively limit the pressure spring 5.

[0025] Working principle and use process of the utility model: The high-travel switch in the technical solution of the utility model completes the on-off of the circuit by pressing the pressure spring 5 down by the rubber head 4. When the rubber head 4 is not under force, the pressure spring 5 separates the contact 43 from the terminal 2 by its own elastic force, which effectively avoids accidental touching. A bending head 44 is provided at the top of the contact 43. The arc surface structure formed by the bending head 44 can prevent the contact 43 from getting stuck with the terminal 2 during the height adjustment process, thereby improving the stability of the detection switch when it moves up and down.

[0026] In the present technical solution, the rubber head 4 is limited and guided through the rubber cover 3 and the pressure spring 5, so that the height adjustment of the rubber head 4 remains stable during the adjustment process, so that the high-stroke detection switch can operate stably and the control accuracy is improved.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to be a further limitation of the present invention. All equivalent changes made using the contents of the specification and drawings of the present invention are within the protection scope of the present invention.
