Description

Variable-arm rotating shaft structure of cassette connector

[ technical field ] A method for producing a semiconductor device

The utility model belongs to the technical field of the connector, especially, relate to a cassette connector becomes arm pivot structure.

[ background of the invention ]

With the rapid development of the internet, mobile network terminal devices such as mobile phones have also been developed rapidly. At present, mobile phones become essential products for most people to live, a phenomenon that the mobile phones do not leave is formed, and the influence of the mobile phones on the life of people is larger and larger. With the increase of demand, the personalized requirements of people are also diversified gradually, and the lightness, thinness, curve and lightness become the mainstream of the mobile phone in the upgrading direction. Due to the use requirements, a mobile terminal is always required by a plurality of people to load a plurality of communication cards, so that a plurality of three-in-one card seats appear in the market, and along with the development of the ultra-thin and multifunctional directions of mobile terminal equipment, the given space of the card seats in the size space of the existing mobile phone is smaller and smaller, and therefore, higher requirements are provided for the structural design of the card seats. The cassette includes iron-clad, metal terminal, pull rod, pivot and rivet, and the cassette holds in the palm the cooperation with the card, and a plurality of communication cards set up on the card holds in the palm, then along with the card hold in the palm insert the cassette, when needs hold in the palm the card and pop out, through the one end that promotes the pull rod and promote the pivot, the drive pivot is rotatory round the rivet, and the other end of pivot will block the support and pop out.

In the prior art, as shown in fig. 1, when the card holder is driven to pop out, the end of the rotating shaft abuts against the front end face of the card holder, and the card holder is pushed out under the action of a lever force arm, through analysis, the force of the pull rod pushing the rotating shaft is denoted as F1, the force arm of the torque generated by F1 on the rotating shaft is denoted as L1, the force of the other end of the rotating shaft pushing the card holder is denoted as F2, and the force arm corresponding to F2 is denoted as L2. In order to meet the requirement of the ejection stroke of the card holder, the L2 needs to be lengthened to rotate and then push the card holder to eject, but when the L2 is lengthened and the F2 is not changed, the pushing force of the F1 needs to be increased, so that the operation force is increased when the card holder is ejected, and the operation is inconvenient and laborious.

Therefore, it is desirable to provide a new arm-variable pivot structure for a card connector to solve the above problems.

[ Utility model ] content

A primary object of the utility model is to provide a cassette connector becomes power arm pivot structure can satisfy the stroke demand that the card held in the palm withdraws from, and has reduced the required operating force when the card holds in the palm withdraws from.

The utility model discloses a following technical scheme realizes above-mentioned purpose: a variable-force arm rotating shaft structure of a chuck connector comprises a first force arm part and a second force arm part which form a lever structure, wherein a first action point A and a second action point B which are sequentially abutted against a card support in the process of pushing the card support to withdraw are arranged on the second force arm part, and the force arm value of the first action point A is smaller than that of the second action point B.

Further, the surface of one side, facing the card support, of the second force arm part is provided with a boss part protruding outwards; the boss portion forms the first point of action a.

Further, the free end of the second force arm forms the second point of action.

Further, there is a difference in distance between the boss portion and the free end of the second force arm portion.

Further, the first force arm and the second force arm are provided with a mounting hole at the intersection and a lever fulcrum at the position of the mounting hole.

Furthermore, a supporting shaft for providing lever support for a rotating shaft is arranged on the mounting hole in a matched mode.

Further, the end of the first force arm has a pushing space in a direction perpendicular to the force arm.

Furthermore, the first force arm part and the force arm direction form an included angle.

Compared with the prior art, the utility model relates to a cassette connector becomes power arm pivot structure's beneficial effect lies in: when the pull rod pushes the end part of the first force arm part upwards by using F1, the second force arm part rotates and the end part pushes the card holder downwards, at the moment, the first action point A firstly abuts against the end part of the card holder, and because the moment arm of the first action point A is smaller, larger thrust can be realized by using smaller action force F1, and the card holder is pushed out; in order to meet the withdrawing stroke of the card support, the second force arm part continues to rotate, the end part pushes the card support downwards, the second action point B slowly abuts against the end part of the card support, at the moment, the action force arm is enlarged, the card support can be driven to move for a larger distance by rotating for the same angle, the card support is separated from the position of a clamping structure of the card seat, and the subsequent thrust requirement is smaller, so that the subsequent card support is pushed more easily; thereby realized becoming the card of arm of force and held in the palm the operation of withdrawing from, satisfied card and held in the palm the stroke and reduced operating force, more laborsaving.

[ detailed description ] embodiments

Example (b):

referring to fig. 2-4, the present embodiment is a variable arm pivot structure 100 of a card connector, which includes a first arm 1 and a second arm 2 forming a lever structure, wherein the second arm 2 includes a first action point a and a second action point B sequentially abutted against a card holder during a process of pushing the card holder to withdraw, and an arm value of the first action point a is smaller than an arm value of the second action point B.

When the pull rod pushes the end part of the first force arm part 1 upwards by using F1, the second force arm part 2 rotates and the end part pushes the card holder downwards, at the moment, the first action point A firstly abuts against the end part of the card holder, and as the moment arm of the first action point A is smaller, larger thrust can be realized by using smaller action force F1, and the card holder can be pushed out; in order to meet the withdrawing stroke of the card support, the second force arm part 2 continues to rotate, the end part pushes the card support downwards, the second action point B slowly abuts against the end part of the card support, at the moment, the action arm is enlarged, the card support can be driven to move for a larger distance by rotating for the same angle, the card support is separated from the position of a clamping structure of the card seat, and the subsequent thrust requirement is smaller, so that the subsequent pushing of the card support is easier; thereby realized becoming the card of arm of force and held in the palm the operation of withdrawing from, satisfied card and held in the palm the stroke and reduced operating force, more laborsaving.

The side surface of the second force arm part 2 facing the clamping end part is provided with a boss part 3 protruding outwards, the boss part 3 forms a first acting point A, the free end of the second force arm part 2 forms a second acting point B, and the boss part 3 and the free end of the second force arm part 2 have a distance difference and the force arm of the first acting point A and the second acting point B has a size change.

The first force arm part 1 and the second force arm part 2 are provided with a mounting hole 5 at the junction and form a lever fulcrum at the position of the mounting hole 5; the mounting hole 5 is used for being matched with a mounting support shaft 4, and the support shaft 4 provides lever support for the rotating shaft.

The end of the first force arm 1 has a pushing space in the direction perpendicular to the force arm. Specifically, the first force arm part 1 and the force arm direction form an included angle.
