Description

Magnetic card reader head mounting structure

Technical field

The utility model relates to a mounting structure of a magnetic card reader magnetic head.

Background technique

Magnetic card readers are used to read and write magnetic card information, and can be widely used in finance, post and telecommunications, commerce, transportation, customs, membership card consumption and point consumption. Magnetic cards are used to store various types of data and can be used in different fields, including electronic payment systems, secure access control systems, and identification systems. Data is usually magnetic stripe magnetically encoded, and data can be read by using a magnetic head.

Magnetic card readers usually use two opposite magnetic card sliding slots. The head is usually mounted in a housing containing all of the electronics inside. The magnetic head can be mounted on the wall of the two opposite magnetic card sliding slots so that when a card is placed inside the magnetic card sliding slot, the magnetic strip on the magnetic card and the magnetic head on the card reader are aligned. When the user slides the magnetic card along the magnetic card sliding slot, the encoded data on the magnetic card is read by the magnetic head. Under normal circumstances, the magnetic card can slide the card data from both directions.

The head assembly is usually mounted on a thin metal sheet with two wing-shaped mounting arms on both sides of the metal sheet, as shown in Figure 1. The metal piece is made of a metal material and has a sensitive elasticity. When the card is slid, the metal piece provides a pressure to allow the head to be retracted before and after to keep the magnetic card and the magnetic head in close contact so as to correctly read the data of the magnetic strip.

If the pressure of the metal piece is too small, the contact force between the magnetic card and the magnetic head may not be sufficient, and the magnetic card and the magnetic head may not be in close contact; on the other hand, if the pressure is too large, it will be difficult to slide the card; in extreme cases, too much pressure Can cause wear and damage to cards or magnetic strips.

In the prior art, many magnetic card reader modules, most of which use a similar design, are mounted with two wings. One of the problems of the prior art is that the frame and the wings increase the overall size of the card reader, and thus cannot adapt to the trend of electronic devices that are currently miniaturized by magnetic card readers. It is not possible to use such a design in a very compact magnetic card reader.

Further, in the prior art, there is also a structure in which a magnetic head is mounted. as shown in picture 2. In this structure, the two wings are provided with a flat elastic arm, which partially solves the problem of size, but the overall size is relatively large, which is not conducive to the miniaturization of electronic equipment.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the above prior art and to provide a compact structure. The mounting structure of the magnetic card reader head is reasonable, and the mounting structure can reduce the mounting size of the magnetic head and maintain the contact force of the magnetic head and the magnetic card.

The mounting structure of the magnetic card reader magnetic head of the present invention is characterized in that it comprises a magnetic card reader magnetic head and a bracket for mounting the magnetic head, the bracket is a metal piece, and the metal piece is provided with a plurality of elastic feet.

Further, the metal piece is provided with a through hole for positioning the magnetic head, and the upper and lower sides of the perforated edge are provided with a tab extending forward or backward.

Further, the elastic foot is a curved elastic piece provided at four corners of the metal piece.

Further, the elastic legs are provided with bent pieces on both sides.

Further, the elastic foot is an arc-shaped elastic piece which is disposed on the side of the perforation and extends toward the side of the perforation.

Further, the magnetic head is fixed to the extended tab by spot welding.

The working principle of the magnetic card reader magnetic head mounting structure of the utility model is that the magnetic head is fixedly mounted on the metal bracket. Since the bracket is provided with a plurality of elastic legs, after the bracket is mounted on the magnetic card reader, the elastic lower foot end surface abuts against the magnetic card. Sliding on the wall surface of the groove, so that when the card is swiped, the magnetic card applies force to the magnetic head and the bracket, and the magnetic head and the bracket are moved laterally backward, and the elastic leg is elastically deformed. After the magnetic card is detached, the magnetic head and the bracket are elastically acted upon by the elastic foot. Revert to the original position.

The metal piece of the invention has no wing structure, which reduces the overall size of the magnetic head mechanism, and at the same time ensures that the metal piece has a certain elasticity, so that the magnetic card has a certain contact force.

detailed description

The present invention will be further described below in conjunction with the embodiments with reference to the accompanying drawings.

The mounting structure of the magnetic card reader magnetic head of the present invention comprises a magnetic card reader magnetic head 1 and a bracket 2 for mounting the magnetic head, the bracket is a metal piece, and the metal piece is provided with a plurality of elastic feet 3, the elastic feet It can be formed by one-time stamping on a metal sheet and form a unitary structure with the entire bracket.

Further, in order to facilitate the fixing of the magnetic head, the metal piece is provided with a through hole 4 for positioning the magnetic head, and the upper and lower sides of the perforated edge are provided with a tab 5 extending forward or backward.

Further, in order to facilitate the fixing of the magnetic head, the magnetic head is spot-welded and fixed to the tab 5 extending forward or backward of the perforated edge.

In the first embodiment, the elastic leg 3 is a curved elastic piece 301 provided at four corners of the metal piece. In this embodiment, for the better positioning, the elastic legs are provided with a bending piece 6 on both sides thereof, and the bending piece 6 is disposed in the hole of the wall surface of the magnetic card sliding groove, and the hole size is weaker than the bending piece 6, The bent piece 6 can be stretched and slid in the hole to play a role of positioning.

In the second embodiment, the elastic foot is an arc-shaped elastic piece 302 extending on the side of the perforation and extending toward the side of the perforation.

In order to ensure the proper contact force between the magnetic head and the magnetic card, the optimal contact force can be achieved by adjusting the thickness of the metal piece, the number of elastic legs, and the size of the elastic foot according to the actual contact size.
