Abstract
The invention provides a circular contact spring slice material strip punching structure which comprises a material strip (20) and a plurality of circular contact spring slices (1) distributed on the material strip (20), wherein the circular contact spring slices (1) are provided with bendable extension parts (11) which are distributed along the texture direction of the material strip (20). In the scheme, the contact spring slices are distributed along the texture direction of the material strip, thus enhancing product functions and service lives.
Description
Technical Field
The invention relates to an annular contact spring sheet material belt punching structure, and belongs to the technical field of machining and manufacturing.
Background
The annular contact spring, i.e. the connector is annular, and has been widely used in high-tech industries such as mobile phones, palm computers, digital cameras, multimedia players, etc., and is usually a contact spring for data connection with an earphone plug. The contact elastic sheet is in over-hard fit with the earphone plug, so that the purpose of stable contact is achieved. Therefore, the requirements on the elasticity and the service life of the contact elastic sheet are quite strict, and the service life is usually required to be more than 5000 times of plugging and unplugging. The process requirement of the contact spring is that the contact spring is made of metal, the raw material is preferably phosphor bronze (C5210R-EH), the electrical conductivity of the contact spring is strong, and the hardness of the contact spring is HV: 210-260 and gold plating to make the elastic sheet keep better elasticity, so as to be not easy to deform during the use.
When preparing such a ring-shaped contact spring, a longitudinal strip stamping method is usually adopted, that is, the whole terminals are vertically distributed on the raw material, and the contact spring is uniformly stamped and formed. It should be noted that, in the conventional material tape punching method, the contact elastic pieces are all arranged longitudinally along the material tape, so that although more contact elastic pieces can be punched in a unit area of the material tape, the service life of the contact elastic pieces is greatly reduced. The reason is that the material belt is also made of processed metal, free grains of the metal exist, and if the material belt is bent along the grains, better elastic sheet performance can be kept; on the contrary, if the elastic sheet is bent perpendicular to the lines, the performance of the elastic sheet is greatly reduced, and the problems of short service life and fast attenuation of the elastic force are caused. The principle is the same as that of a bamboo, the bamboo can be easily split along the lines of the bamboo, and the splitting is difficult to be longitudinally removed.
Therefore, there is a need for further improvements in the prior art.
Disclosure of Invention
The present invention is directed to solve the above problems, and provides a stamping structure for an annular contact spring strip, which can provide a long service life.
The purpose of the invention is realized by the following technical scheme:
the utility model provides an annular contact shell fragment material area punching structure, includes the material area and arranges a plurality of annular contact shell fragments on the material area, and annular contact shell fragment has the extension of buckling, the extension is arranged along the line direction in material area.
Wherein,
the annular contact elastic sheet is in a lengthwise shape and comprises a main body, and the extension part extends out from one end of the main body. The main body is positioned on two sides of the extension part and is connected with the material belt through a terminal pin. The terminal pins are connected with the material belt in a pre-breaking mode.
The beneficial effects of the invention are as follows: through arranging the contact spring piece along the grain direction of material area, improved product function and life.
Drawings
The technical scheme of the invention is further explained by combining the accompanying drawings as follows:
fig. 1 is an expanded view of the annular contact spring of the present invention.
Fig. 2 is a side view of an annular contact spring.
Fig. 3 is a schematic view of a punching structure of the annular contact spring strip in the invention.
The relevant elements in the figures are numbered correspondingly as follows:
1. annular contact spring piece 10, main bodies 11 and 12 and extension parts
13, 14, terminal pin 20, material belt
Detailed Description
The invention is described in further detail below with reference to the figures and the embodiments.
As shown in fig. 1, the annular contact spring 1 is substantially in a longitudinal shape, and includes a main body 10 and extending portions 11 and 12 respectively extending from two ends of the main body 10, wherein one of the extending portions 11 can be bent to function as a spring. Referring to fig. 2, after the extension portion 11 is bent, it approaches the main body 11 to form a U shape as a whole.
Referring to fig. 3, when manufacturing the annular contact spring, a material belt punching structure of the annular contact spring is adopted, that is, a plurality of contact springs 1 are uniformly punched on an entire raw material belt 20. It should be noted that the contact domes 1 are arranged along the grain direction a of the material strip 20, that is, along the material strip 20. The main body 10 of each contact spring 1 is located on both sides of the extension portion 11, and is connected to the carrier tape 20 through one terminal pin 13, 14.
It should be noted that the connection between the terminal pins 13 and 14 and the material strap 20 is a pre-break connection, that is, the user only needs to bend the contact elastic piece 1 slightly to separate the material strap 20 from the contact elastic piece 1 and use the contact elastic piece normally.
This scheme is arranged through the line direction with the contact shell fragment along the material area, has improved product function and life, and through life-span test, traditional product shell fragment elasticity life-span can only reach 3500 and every 1000 times of plug elasticity with 20% decay, and the product life-span of this scheme production can reach more than 7500 and every 1000 times of plug elasticity with 3% decay, and the result is greater than market requirement far away, and its potential interest is very big.
