Embodiment 1
[0022] like figure 1 As shown, a pressing process of metal pins for touch film connectors, the following steps:
[0023] 1. Pierce the pin from the back of the touch film, use the pressure mold to bend the pin on the conductive surface, and after the front is bent, the tip of the tooth penetrates into the conductive ink. This process is formed at the bend of the tooth The curved surface is relatively flat.
[0024] 2. The pressing film tool includes an upper mold 1 and a lower mold 2. The lower end surface of the upper mold 1 is provided with a notch 1-1, and the pins are bent at the notch 1-1. After bending, the pins are excessively flat. The upper end surface of the lower mold 2 is provided with a positioning metal sheet 2-1, so as to ensure that the pins are bent in one direction, the sealing effect is good, and the stability of the product is guaranteed.
[0025] 3. The pins in the connector need to be longer than the commonly used pins, so that there is enough length t...

Abstract
The invention discloses a pressing process of a metal pin for a touch film connector, which includes selecting a uniform pin with a tooth length of 1.8 mm, using a pressing mold, an upper mold with a notch, and bending the pin at the notch. After bending, the pins are too flat. Because the teeth of the product are long, the ink can be completely pierced after bending. The lower mold has a metal sheet for positioning the pins, so that the pins are bent in one direction, and the sealing effect is good. Stability of the product; by using anti-salt silica gel to protect the broken part of the conductive ink, the ink is isolated from the salt mist, and prevents the ink from being corroded and oxidized. The oxidation level and the use environment meet the use requirements in harsh environments such as kitchens and outdoors. The main control board of the client can meet the use requirements without sealing the connector, saving the customer's assembly time.
Description
technical field [0001] The invention relates to a pressing process of a metal pin for a touch film connector, and belongs to the technical field. Background technique [0002] From button-type mobile phones more than ten years ago to resistive screen mobile phones, to the capacitive touch screens we use today. Traditional mechanical switches have gradually withdrawn from the consumer market, and micro switches and resistive switches have been replaced by touch capacitive switches. At present, mobile phones and home appliances are being updated with each passing day, and capacitive touch has always existed in these hardware as a core technology. [0003] With the update of technology, the reliability of materials and processes has also changed. At present, in the home appliance industry, touch panels have accounted for more than 95% of the share. The core control switch capacitive touch diaphragm is used in different fields. Multiple reliability tests are required. Among t...
