Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to improvements in electrical connectors, particularly multi-terminal connectors with multiple glue receptacle contacts for printed wiring boards.

(Prior Art) Wiring connections for computers, telephone exchanges, etc. require not only high reliability of electrical contact, but also miniaturization and high-speed drive. High-density packaging is required. The connector used to connect such wiring has a receptacle housing with a large number of receptacle contacts (female contacts) fixed to one printed wiring board, and a large number of post terminals (female contacts) on the other printed wiring board. By fixing the header housing with the male side contact and connecting both housings, the numerous post terminals built into the header housing can be inserted and connected to the numerous post terminals built into the receptacle housing. I have to.

(Problems to be Solved by the Invention) Such a connector is convenient because it can connect a large number of terminals at the same time, and its form is compact and integrated, allowing for high-density mounting. There is a problem in that the insertion force at the time of insertion and connection becomes large because the two are connected at the same time.

In addition, in multi-terminal connectors that have ground contacts, signal contacts, and power contacts, electrical noise will occur if these connections are made at the same time.
This may adversely affect data and circuits.

(Means for Solving the Problems) Therefore, the multi-terminal connector of the present invention is provided for grounding, power supply,
The connection timing of the signal contacts is shifted in three stages so that they are always connected in this order.This reduces the insertion force and prevents noise generation and IC failure.
This improves reliability. That is, the ground terminal is connected first, then the power source is connected, and then the signal terminal is connected.

(Example) Hereinafter, the present invention will be explained in detail with reference to the drawings.

The first wiring board 1 has a plurality of post terminals 1 whose tips are aligned.
A receiving type header housing 10 having 0a to 10d is fixedly installed. Among the post terminals 10a to 10d, 1
0a and 10b are for grounding, IGc is for power supply, and 10d is for signal, and each of them is connected to a predetermined terminal of first wiring board 1.

A receptacle housing 20 and a support plate 21 are fixed to the second wiring board 2.
There are many glue receptacle contacts 20a to 20d in 0.
is equipped with. The legs 21a to 21d of each receptacle contact are fixedly connected to the second wiring board 2. First and second glue receptacle contacts 20a
, 20b is for grounding and is located at position A closest to the entrance,
The third 20c is for the power supply and is located at the next closest position B, and the fourth 20d is for the signal and has a contact portion at the deepest position C, furthest from the entrance.

The receptacle housing 10 is inserted into the header housing 10 with a large number of receptacle contacts 20a to 20d built therein, so that each receptacle contact 20a to 20d clamps each post terminal 10a to 10d as shown in the drawing, and both electrically connected.

At this time, the grounding post terminals 10a, 10b and receptacle contacts 20a, 20b are first connected, then the power supply post terminals 10c and receptacle contacts 20G are connected, and finally the signal post terminals 10d and receptacle contacts 20d are connected. is connected.

The shapes of the receptacle contacts 20a to 20d may be the same and may be shifted only in position, or may have different lengths. In any case, the position of electrical contact with the post terminal may be shifted as described above. The electrical connection of the contact is also a mechanical connection, so by connecting the contacts in three stages in this order, the insertion force when connecting the connector is not concentrated all at once, and the insertion force is divided into three steps. The force is dispersed, making insertion easier, which is favorable for operation.

(Effects of the Invention) The multi-terminal connector according to the present invention can be used for grounding,
Since the contacts for power and signals are arranged at different contact positions, there is a possibility that the circuit will malfunction when connected.
It does not generate noise, has the effect of protecting the circuit, and has the advantages of requiring little insertion force and making the connection work easy.

Claims (1)

[Claims] In a receptacle housing equipped with three types of contacts: a grounding contact, a power supply contact, and a signal contact, when inserting and connecting the post terminal of the male side contact with the same tip position into the housing, the post terminal is connected to the grounding contact, A multi-terminal connector characterized in that the contact positions of these three types of contacts are staggered so that the power contact and the signal contact are connected in that order.
