Detailed Description
The ceramic temperature sensor shown in fig. 1 includes a sensing element 1 and a cable 2, wherein a pin 1A of the sensing element 1 is inserted into a connection end of a bare cable core wire 2A and is welded and fixed with the connection end.
The connection position of the sensitive elements 1 and the cables 2 is provided with an insulating spacer 3, and the insulating spacer 3 penetrates through the pins 1A of the two sensitive elements 1 and the two cable core wires 2A. In this embodiment, 3 both sides below of insulating spacer is equipped with support boss 3A, and 3 both sides tops of insulating spacer are equipped with spacing boss 3B, support boss 3A and play the supporting role to 1A of pin of sensing element and the cable heart yearn 2A of being connected with it, and spacing boss 3B then plays limiting role, has further improved connection stability. It should be noted that, in the specific implementation, the structure and material of the insulating spacer 3 are very flexible, for example, a high temperature resistant heat shrinkable sleeve, a high temperature resistant adhesive tape, a high temperature resistant plastic spacer or a ceramic spacer may be used.
The sensing element 1 and the connecting position of the sensing element and the cable 2 are sleeved with a ceramic tube 4. Namely, the sensitive element 1 and the connecting position of the sensitive element and the cable 2 are welded, and the insulating spacer 3 is installed, and then the adhesive is dispensed and packaged in the head ceramic tube 3. In this embodiment, the ceramic tube 4 is a blind tube with one end open and the other end closed, and the inner cavity and the outer shape are both circular structures. However, in specific implementation, the ceramic tube 4 may have other deformation structures, such as a through tube with two open ends; if the inner cavity is a circular cavity type, the outer shape is a rectangular structure so as to be convenient for installation and grasping. The cable 2 is externally sleeved with a protective sleeve 5.
