Detailed Description
Example one
A pin needle of a thin film touch sensor comprises a needle head 3 and a needle tube 4; needle tube 4 is the tubulose, needle tube 4 internal fixation has needle body 2, syringe needle 3 bonds on the needle body 2, and the other end extends the head end setting of needle tube 4, syringe needle 3 has and is used for the sealed cavity of inflatable, syringe needle 3 with the material of needle body 2 is electrically conductive silica gel, needle body 2 does not have and is used for the sealed cavity of inflatable. Needle body 2 can not aerify for 2 relative syringe needles 3 of needle body, 2 hardness of needle body are greater than the hardness of syringe needle 3, and when the test, wait to survey the product with syringe needle 3 contact, syringe needle 3 is electrically conductive silica gel, and electrically conductive silica gel material is comparatively soft, makes syringe needle 3 can not damage and wait to survey the product. In the test process, 3 contacts of syringe needle and waits to electrically test the product, and needle 2 with wait to electrically test product extrusion syringe needle 3 because syringe needle 3 has and is used for the sealed cavity of gas filled, aerify in the syringe needle 3, syringe needle 3 has elasticity, 3 back syringe needles of 3 backs of lifting up of syringe needle do not contact with waiting to electrically test the product, and syringe needle 3 utilizes the elasticity of self to reset, makes things convenient for next test.
The tail end of the needle tube 4 is fixed with a needle cap 1, and one end of the needle body 2 far away from the needle head 3 is connected with the needle cap 1 in a viscose mode.
In order to limit the size of the needle 3 extending out of the tube 4, the size of the end of the needle 3 extending out of the tube 4 is smaller than the size of the other end of the needle 3. The size of the needle tube 4 is larger than that of the needle body 2.
The needle tube 4 is formed by splicing a connecting part 4-2 and a main body part 4-1, fins 6 used for fixing the connecting part 4-2 and the main body part 4-1 are arranged on the connecting part 4-2 and the main body part 4-1, and the needle head 3 is arranged at one end, far away from the splicing part 7, of the main body part 4-1. The number of the fins 6 on the connecting part 4-2 and the main body part 4-1 is two, and the two fins 6 are respectively arranged symmetrically about the axis of the connecting part 4-2 and the axis of the main body part 4-1. Semicircular grooves are formed in the fins 6, and the semicircular grooves of the fins 6 in the connecting portion 4-2 are matched with the semicircular grooves of the fins 6 in the main body portion 4-1 to form glue injection grooves 5. The needle tube 4 adopts the concatenation mode, conveniently puts into needle body 2 and needle body 2 in the needle tube 4, after needle body 2 and needle tube 4 have put into place, then aligns each other main part 4-1 and fin 6 on the connecting portion 4-2, injects glue in the injecting glue groove 5 that two fins 6 formed for main part 4-1 and connecting portion 4-2 of needle tube 4 connect and form an organic whole. The needle head is also fixedly provided with a contact disc 9, and the head end of the needle head extends out of the contact disc 9.
The working principle is as follows:
example two: the difference from the above embodiment is that: the needle head 3 is not provided with a sealed cavity for inflation, the needle body 2 is provided with a sealed cavity for inflation, and the cavity in the needle body 2 is inflated, so that the hardness of the needle head 3 is greater than that of the needle body 2. When the needle 3 contacts a product to be electrically tested, the needle 3 is conductive silica gel, so that the product to be electrically tested cannot be damaged; full gas is filled in the 2 cavitys of needle body, has better elasticity, and syringe needle 3 contacts and waits to survey the product, and needle body 2 receives the extrusion of syringe needle 3, and syringe needle 3 is carried back syringe needle 3 and is not surveyed the product contact with waiting to survey, and 3 elasticity are applyed for syringe needle 2 for syringe needle 3 resets fast, makes things convenient for test next time.
Example three: the difference from the above embodiment is that: syringe needle 3 with needle body 2 all has and is used for the sealed cavity of inflatable, aerifys in needle body 2 and syringe needle 3 for syringe needle 3 and needle body 2 all have better elasticity, and when the test, syringe needle 3 contacts and waits to survey the electricity and survey the product, and syringe needle 3 is conductive silica gel, and conductive silica gel material is comparatively soft, makes syringe needle 3 can not damage and wait to survey the electricity and survey the product. In the test process, 3 extrusion needle bodies 2 of syringe needle, 3 resilience forces of syringe needle are applyed to needle body 2 for syringe needle 3 pops out fast because the resilience force that elasticity and needle body 2 of self exerted and resets, makes things convenient for next test.
