Description

Terminal and connector using it {Terminal and connector having the same}

The present invention relates to a connector having terminals for electrically connecting between substrates, for example.

Terminals are generally installed within the connector's housing to make electrical connections. Terminals can be combined with other terminals to make electrical connections. However, the terminal may be electrically connected to the board through the through hole of the board. In particular, both ends of the terminal may be inserted into throughholes of boards facing each other to electrically connect the two boards.

In Prior Documents 1 and 2, terminals are directly electrically connected between substrates. However, insulation problems may occur if terminals electrically connecting boards are exposed.

In order to solve this problem, a separate insulation structure may surround the terminal, but the insulation structure made separately from the terminal has a problem in that installation work is inconvenient.

In the case where terminals directly connect substrates to substrates, there are press-fitting structures at both ends of the terminals, and these press-fitting structures are press-fitted into through-holes of the terminals and, if necessary, soldered to perform electrical connection.

However, when there is a press-fitting structure at both ends of the terminal, it is impossible to install the terminal in the housing, and thus it is impossible to make a connector having a structure in which the terminal is press-fitted while penetrating the housing.

When the second body 22 is press-fitted into the terminal seating space 12, the second press-in projection 25' penetrates the inner surface of the terminal seating space 12 and can be press-fitted. The second stopper 23' can regulate the degree to which the second body 22 is inserted into the terminal seating space 12.

In this way, when the first body 21 and the second body 22 are inserted into the terminal seating space 12, the first coupling irregularities 30 and the second body 22 of the first body 21 The second coupling irregularities 30' of may be coupled to each other. 4 shows a state in which the first body 21 and the second body 22 are coupled in the terminal seating space 12 of the housing 10 .
