The present invention relates to an anchor structure and particularly to an anchor structure for electronic card connector pins.
Electronic card connectors are widely used on different electronic devices these days. The electronic card connectors have many different types corresponding to different specifications of electronic cards to establish electric connection between the electronic cards and the electronic devices through a pin structure located in the connectors.

In the event that the length of the pins 2 exceeds a certain range, the two ends of the pins 2 are spaced from each other at a greater distance. Hence during the process of inserting the pins 2 into the receptacle 1, skew, bending, deformation or fracturing of the pins 2 is prone to occur. In some cases the pins 2 and the receptacle 1 are integrally formed through an injection forming process. As the pins 2 are spaced from one another densely, a greater precision is required, otherwise production yield decreases. Moreover, the pins 2 have a bare middle portion. This easily causes short circuit when energized with electricity. These issues related to the electronic card connector pins remain to be overcome in the industry.
The primary object of the present invention is to provide an anchor structure for electronic card connector pins to avoid the pins from skewing, deforming or fracturing during insertion process of the pins into electronic card connectors.
To achieve the foregoing object the anchor structure of the invention aims to anchor a plurality of pins to facilitate insertion. It has an anchor member held on a receptacle and extended from a coupling port of the receptacle. The anchor member has a plurality of holding spaces and each holding space holds one pin. Each of the holding spaces has an insertion track to confine and guide the pin to facilitate insertion.
Another object of the invention is to prevent short circuit from occurring in the middle portion of the pins. To achieve this object the anchor member contains insulation material.
Yet another object of the invention is to enhance the sturdiness of the pin structure. To achieve this object the middle portion of the pins and the surrounding wall of the holding spaces are in contact with each other.
The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.

The invention further has an anchor member 3 held on a receptacle 1 and extended from a coupling port 10 formed on the receptacle 1. The anchor member 3 has a plurality of holding spaces (such as holding troughs or openings). Each of the holding spaces holds one of the pins 2. Each holding space also has an insertion track (not shown in the drawings) to anchor and hold the pin 2 in the holding space to facilitate insertion of the pin 2 into the receptacle 1. In this embodiment the anchor member 3 mates the pin 2 and is extended from the coupling port 10 along the pin 2 to the bend portion of the pin 2. The anchor member 3 has an insulation material inside to prevent short circuit in the middle portion 20 of the pin 2. Moreover, the holding space has a holding trough 30 which has a surrounding wall in contact with the middle portion 20 of the pin 2 to enhance the sturdiness of the pin 2. In addition, the insertion track is formed in the axial direction of the holding trough 30.

As a conclusion the anchor member 3 of the invention provides anchor function for the pins 2 during insertion into the receptacle 1. Hence skewing, deformation or fracturing of the pins 2 that might otherwise happen during the insertion process can be prevented. Moreover, the anchor member 3 provides insulation and can prevent short circuit from taking place in the middle portion 20 of the pins 2. As the middle portion 20 of the pins 2 is in contact with the surrounding wall of the holding space, the sturdiness of the pins 2 can also be enhanced. Thus the invention provides a significant improvement over the conventional techniques.
