Description

Technical Field

[0001] The utility model relates to the technical field of hardware accessories, in particular to a contact type spring piece. Background Art

[0002] The contact spring belongs to the category of hardware springs and electronic hardware materials. It is an important component of various electronic products (mobile phones, connectors, car batteries). It is made of metal materials. When the contact spring installed on the conductive film is pressed, the center point of the spring contacts the PCB board to form a loop. The current passes through it and has the characteristics of strong conductivity and good feel.

[0003] During use, the pressure generated by pressing the spring piece by hand is uncontrollable, and the load may exceed the normal preset pressure value of the spring piece, which may cause overtravel and damage the spring piece. Excessive compression may also cause scratches on the spring piece by sharp objects or nails. In response to this technical problem, the present application proposes a contact spring piece.

[0007] Furthermore, the protective component includes a first vertical pin shaft fixedly connected to one side of the top of the spring body, a second vertical pin shaft fixedly connected to the other side of the top of the spring body, the inner wall of the protective top plate is respectively slidably connected to the outer wall of the first vertical pin shaft and the second vertical pin shaft, and the spring body is connected to the protective top plate through a spring.

[0008] Furthermore, the bottom end of the spring is fixedly connected to the inside of the spring body, and the top end of the spring is fixedly connected to the inside of the protective top sheet.

[0009] Furthermore, a protective shell is rotatably connected to the top rear side of the spring body, and the protective shell is made of acrylic plate material.

[0010] Furthermore, the inner wall of the protective shell is snap-connected to the top of the protective bottom film.

[0012] Furthermore, the inner wall of the circular hole is rotatably connected with a flip cover, and the flip cover and the middle part of the protective top sheet are both fixedly connected with a semicircular ring.

[0013] The utility model has the following beneficial effects:

[0014] 1. In the utility model, a protective top sheet and a protective bottom sheet are respectively arranged on the upper and lower sides of the spring sheet body. The arrangement of the protective bottom sheet can protect the outer walls of both sides of the spring sheet body to avoid friction damage. When the top of the spring sheet body is subjected to downward pressure, the protective top sheet presses the spring downward under the cooperation of the first vertical pin shaft and the second vertical pin shaft to buffer and disperse the squeezing force.

[0015] 2. In the utility model, the spring cooperates with the first vertical pin shaft and the second vertical pin shaft to enable the protective top plate to move up and down stably, thereby protecting the top of the shrapnel body. The protective shell is rotated to cover the top of the shrapnel body to protect it. The acrylic protective shell is convenient for distinguishing the model and specification of the internal shrapnel body. The flip cover on the inner wall of the circular hole can be opened for use on the shrapnel body. BRIEF DESCRIPTION OF THE DRAWINGS
