Embodiment Construction

[0030] The present invention will be further explained below in conjunction with the drawings and specific embodiments:

[0031] Refer to image 3 with Figure 4 Shows the structure of the card connector terminal 10 of this embodiment, which specifically includes a substrate 100. The tail end of the substrate 100 is a soldering pin 110 for soldering with a circuit board, and the front end of the substrate is provided for electrical connection with an electronic card. The elastic contact arm 120 is formed by integrally extending from the substrate 100 obliquely upwards. The elastic contact arm 120 has a long slot 130 formed by making the elastic contact arm 120 under the elastic contact arm 120.

[0032] Wherein, the elastic contact arm 120 includes an elastic arm portion 122 formed by piercing and a contact portion 121 formed by cutting and molding. The contact portion 121 is located at the extension end of the elastic arm portion 122, and the elongated slot 130 includes The first...

Abstract

The invention relates to a card connector terminal and a method for manufacturing the same, which includes a substrate having an elastic touch arm electrical connected with an electronic card. The elastic touch arm is formed by integrated extension upswept from the substrate, the elastic touch arm down part has a strip groove hole formed by manufacturing the elastic touch arm. The elastic touch arm includes an elastic arm part formed by piercing, a touch part formed by material cutting moulding; the strip groove hole includes a first region formed by material cutting, and a second region formed by piercing. The touch part width is less than the first region width of the groove hole, the elastic arm part width is same with the second region width of the groove hole, so the elastic touch arm being clamped in the first region of the groove hole can be avoided when the elastic touch arm is extruded deformed, and working performance of product is increased. In another side, using metal board fully can ensure effective width of the elastic arm part, so the elastic arm part has better deformation stress, and can get better service time.

Description

Technical field [0001] The present invention relates to the field of card connector technology, in particular to a terminal used in a card connector and a manufacturing method thereof. Background technique [0002] As we all know, the main function of the card connector is to insert various electronic cards to form the telecommunications transmission between the electronic card and the circuit board. For example, the signal of the inserted memory card, multimedia card, secure digital card, etc. The card connector is transmitted to the reader to read the relevant data. The main structure of the card connector is to use a plurality of contact terminals as the telecommunications transmission between the electronic card and the circuit board. Refer to figure 1 It is the specific structure of a single card connector terminal 10' that is commonly available on the market. Usually the soldering pin 110' at the end of the terminal 10' is connected to the circuit board, and the other end ...
