The slightly different structure of embodiment.
The conductive shell 52 of connection terminal；62 are formed in herein by the metallic plate for being converted into U-shaped, to limit parallel relative two
Individual main wall 52A, 52B；62A, 62B and with the two main wall 52A, 52B；The joining end wall 52C of 62A, 62B；62C (Figure 20
With 24).
In the 5th embodiment 50 of the connection terminal shown in Figure 20-23, chip type spring 51 is manipulated into circular arc.Chip bullet
Spring pass through housing 52 the first main wall 52A so that the chip type spring 51 correspond to the chip type spring 51 in two freedom
The middle body 51A (Figure 20) of hump between end is resisted against the main wall 52B of second relative with the first wall of housing 52
On, thus prestress is in second wall 52B (Figure 20).
By this way, the middle body 51A of chip type spring 51 enduringly housing 52 the second main wall 52B inner surface
Upper application pressure.
More properly, each in the two free ends of the chip type spring 51 has the housing 52 for connection terminal 50
The access portals that pass through of the first main wall 52A.The two access portals form the portion being assembled to chip type spring 51 on housing 52
Part.
In the 6th embodiment 60 of Figure 24-27 connection terminal is shown in, chip type spring 61 is made up of plate, in the plate
Centre part 61A is shown partially cut and bent.
The circumferential portion 61A of the plate forms framework, the framework perpendicular to housing 62 longitudinal axis and surround the housing 62
Extension, so that the middle body 61B of the bending of the plate extends between main wall 62A, 62B of the opposition of the housing 62.
The middle body 61B of bending free edge is pressed against a main wall 62B (Figure 24) of housing 62.The free edge to
The internal bend of housing 62, in order to which intermediate contact elements to be introduced to middle body 61B and housing 62 in chip type spring
In corresponding connection terminal between main wall 62B.
The embodiment of connection terminal should be, connection terminal 10；20；30；40；50；60 housing 12；22；32；42；52；
62 wall is by least one connection pawl 13；23A、23B；33A、33B；43；53；63 extend (Fig. 1,6,11,16,20,24,
29th, 30,36 and 37).
In fact, it is provided with multiple connection pawls.
These connection pawls 13；23A、23B；33A、33B；43；53；63 have dual-use function：On the one hand, they ensure corresponding
The conductive shell 12 of connection terminal；22；32；42；52；62 with by support plate 110；210；310；410；510；610；710；810
The electrical connection of the printed circuit of supporting, on the other hand, connection terminal is mechanically held on the support plate by they.
In order to ensure that the electrical connection and the machinery are kept, at least one connection pawl 13 of each connection terminal；23A、23B；
33A、33B；43；53；63 brazing filler metals are in support plate 110；210；310；410；510；610；710；On 810 printed circuit.
It is contemplated herein that two kinds of connection pawl.
The connection pawl of the first kind is referred to as penetration type connection pawl below, and it is presented in all embodiments shown.
Such as the connection pawl 13 of the conductive shell of the first, second, third and fourth embodiment of connection terminal；23A；33A；43；53；
63 (Fig. 1,6,11,16,20,24,31 and 36).
Each penetration type connects pawl 13；23A；33A；43；53；63 pass through support plate 110；210；310；410；510；610；
710；810 corresponding perforate, so that conductive shell 12；22；32；42；52；62 from first table on the surface of the support plate
Face 111；211；311；411；511；611；711；811 extensions, and protrude the electrical connection pawl and be revealed in the another of support plate
Surface 112；212；312；412；712；812 (Fig. 1,6,11,16,20,24,31 and 36).
Each penetration type connects pawl 13；23A；33A；43 are presented the shape of tongue pieces, and it is from conductive shell 12；22；32；42
Extension of the free edge along the respective wall of housing-i.e. parallel to longitudinal axis-extension of the housing.The longitudinal axis pair
Should be in the longitudinal axis for the case follower for forming first, second, third and fourth embodiment.
In a kind of modification, such as in the case of the 5th and the 6th embodiment, some penetration types connection pawl 53；63 (figures
20 and 24) curve elbow：They are along the profile of stairway step from the housing 52 oriented towards support plate；62 free edge direction
The housing 52；62 outside extension.
Penetration type connects pawl 13；23A；33A；43；53；63 free end can be straight (Figure 15,16,20,24) or
With angle of chamfer (Fig. 1,6,11) in order to being plugged the corresponding perforate through support plate.
The penetration type connection pawl 13 of terminal；23A；33A；43；53；63 allow effectively to be mechanically held in connection terminal
On support plate and to another surface 112 by the support plate；212；312；412；512；612；712；The printing electricity of 812 supportings
Road powers.
Therefore, being for example somebody's turn to do for support plate is fixed and/or be electrically connected to each penetration type connection pawl by bonding or brazing filler metal
On another surface.Preferably, penetration type connects pawl brazing filler metal on the printed circuit by another surface bearing of support plate.
Some embodiments of connection terminal provided herein also include the connection pawl of Second Type, and the connection pawl is below
Referred to as non-through formula connection pawl 23B；33B (Fig. 6-14,30,32,37 and 39).
Each non-through formula connection pawl 23B of conductive shell；33B is against support plate 210；310；710；810 the first table
Face 211；311；711；811.
Connection terminal non-through formula connection pawl enhance connection terminal on support plate machinery holding, and allow to by
The first surface 211 of support plate；311；711；The printed circuit power supply of 811 supportings.
Therefore, for example support plate is fixed and/or be electrically connected to each non-through formula connection pawl by bonding or brazing filler metal
On the first surface.Preferably, the connection pawl brazing filler metal of non-through formula is on the printed circuit of the first surface supporting by support plate.
