If a package or the like is carelessly inserted into a system that is constantly running, such as an electronic exchange, an abnormal current will flow during connection, causing the system to go down. In order to prevent this, the power supply terminal of the package was made into a long and short pin terminal as shown in Figure 2, and the circuit was protected by utilizing the time difference when inserting the package at an appropriate speed. . In this figure, 3 is a package, 5 is a package side connector, 8 is a sequence pin longer than other pins, and 9 is a standard pin.

However, since the insertion of the package is done manually, the insertion speed varies widely and has large variations.If the insertion speed is too fast, the circuit will not be protected and the system will go down. The point was hot. In an attempt to solve this problem, there have been attempts to increase the difference in pin length, but there are limitations because if the sequence pin 8 is made too long, it will bend and cannot be fitted. It was difficult to resolve.

In order to solve the above-mentioned problems, a rotating ejector having a T-shaped part is provided on the package cage, and the ejector is temporarily stopped just before the connector is mated when the package cage is inserted into the shelf that stores the package cage. A stopper portion through which the ejector is rotated and a T-shaped notch through which the ejector can pass when rotated are provided.

確保できる。[Function] When the package cage is inserted into the shelf, the ejector hits the stopper part of the shelf, and then the ejector is rotated to pass through the T-shaped notch and further inserted, mating the connector of the package cage and the connector of the back board. let After the ejector passes through the notch, the distance it must be pushed until the connector is mated is short, so there is a strong tendency for the ejector to perform the mating motion with finger or wrist movements, slowing down the insertion speed and reducing circuit protection when mating the connector.

An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of the embodiment, in which 1 is a shelf;
2a is a stopper portion, 2b is a T-shaped notch, 3 is a package, and 4 is an ejector. Shelf 1
A groove is formed by bending the front part into which the package cage 3 is inserted, and a stopper part 2a and a notch 2b are provided at the frontmost part of the groove. Further, the ejector 4 is rotatably attached to the package cage 3, and consists of a T-shaped tip portion 4a and a lever portion 4b.
The relationship between the stopper portion 2a, the notch 2b, and the tip 4a of the ejector 4 is such that the notch 2b allows the tip 4a to pass only when the direction of the rotation angle of the tip 4a coincides with the normal direction of the notch surface. At other times, the stopper portion 2a is configured to prevent the tip portion 4a from passing. Therefore , in the figure, the first dimension W 1 of the notch 2b is smaller than the width X 1 of the tip 4a of the ejector 4 and larger than the width X 2 of the ejector 4 excluding the tip 4a, and the second dimension W 2 is set larger than the width X 1 of the tip portion 4a.

Next, the lever portion 4b of the ejector 4 is operated to rotate the ejector 4, and the distal end portion 4a of the ejector 4 is caused to pass through the notch of the shield 1. Thereafter, as shown in FIG. 3b, the package 3 is pushed to fit into the connector 5 on the package side and the connector 6 attached to the backboard 7.

As explained above, by providing the T-shaped part in the ejector of the package cage and providing the stopper part and the T-shaped notch in the shelf, when the package cage is inserted into the shelf, the T-shaped part of the ejector will be removed from the stopper. This prevents the system from going down due to mating of a connector with an excessively fast insertion speed. In addition, the connector can be mated by simply inserting the package cage slightly after rotating the ejector, so you only need to press with your finger or wrist, which slows down the insertion speed and helps protect the circuit when mating the connector. This secures time and prevents system failures.
