Therefore, the purpose of this invention is to provide a kind of improved structure, according to this point, some parts that are connected to conductive plate and printed substrate are reduced and have saved producing cost.In addition, the present invention makes littler that terminal box can do.
In application on the spot of the present invention, a branch Junction box assembly is provided, it is made up of one or more conductive plates, and each conductive plate has a contact portion at least in connection.Similarly, provide one or more flexible print circuit boards, each plate all has a contact portion in electrical connection.Contact-segment of the two and contact portion are configured in the box body that has an electric connector carriage and are spaced from each other.Connector leaves an assembly space in box body, in this position, be the electrical connection that is used to have contact-segment and contact portion.In this mode, conductive plate and printed substrate are electrically connected mutually by above-mentioned connector.
In the preferred construction of invention, connector is movably in box body.Like this, connector is inserted in the box body, it is contacted between contact-segment and contact portion and is moved.Therefore, this backlash circuit makes the effect of connector such as the switch of same on/off.
Contact-segment and contact portion need be parallel to each other.Connector should comprise the coupling part and a contact-segment and the contact portion that have two terminals that are parallel to each other at least.Terminal is shaped like this, and it is inserted in the carriage of electric connector, and therefore contact-segment, makes the two electrical connection between them.One of terminal also contacts with the contact portion of flexible print circuit board.In this method, circuit is formed between conductive plate and the wiring board with very simple and economical mode fully.
Projection enters the space and contact portion is supported on the there.In this way, terminal can bear firm opposing and do not have the distortion risk.When connection was finished, contact portion was clipped between a terminal and the boss.
Terminal is resilient, as having added coefficient of safety to guarantee good electrical connection.The coupling part of connector also needs to append on the box body; In this way, connector does not have loosening succinctly and firmly being assemblied in the box body of terminal box.
In the accompanying drawing of this paper, identical reference marker is represented identical parts,
Fig. 1 represents the partial sectional view that connector and terminal box are separated; And
Fig. 2 represents that connector all inserts the structural representation of terminal box.
Flexible print circuit board 17 is at the lower surface of box body 12 and be preferably the three-decker form, comprises a counterdie, a conductive layer (such as copper foil) and a coverlay.The be exposed surface of the contact portion 17a that parallels with the contact-segment 15a of conductive plate of conductive layer.Contact portion 17a is that the end by wiring board 17 is bent to form and is inserted in the connector tray 13 so that be placed on the position that the boss 14a of insulator 14 faces toward.Contact-segment 15a and contact portion 17a are parallel to each other and at the shaft core position of connector tray 13.
Because the strain of terminal 23 and 24 has been impelled the formation of electrical connection good between contact-segment 15a and the contact portion 17a.For the first terminal 23 contact contact portion 17a, inlet 20b is provided in the coupling part 21.
From two width of cloth accompanying drawings as can be seen, connector 20 is fitted into connector tray 13.Contact-segment 15a through socket 26 by so that between first and second terminals 23 and 24, stepped up.Simultaneously, the first terminal 23 by inlet 20b firmly contacts with contact portion 17a.Can find out well that from Fig. 2 terminal 23 and 24 flexibly is out of shape and can exerts pressure to guarantee good electrical contact on contact-segment 15a and contact portion 17a.
The invention provides a simple mechanism that is used to connect conductive plate and gentle shape wiring board.Single connector is introduced in the connector tray and how complete required circuit not.Like this, just do not need connector to arrive conductive plate and flexible circuit board respectively.This has reduced the quantity of parts and has simplified assembling widely.After having reduced parts, artificial situation about occurring also reduces thereupon.
In addition, reduce number of components and also dwindled the space, therefore, terminal box can be done forr a short time.In addition, because the mobile and insertion of connector, circuit can be switched on or disconnect.Like this, connector of the present invention just can be finished switching function.
In one of preferred embodiment of invention, contact portion and contact-segment are parallel to each other and towards the direction of insertion of connector.Similarly, the contact terminal in the contact-segment also can be mutually and is parallel with contact portion with the contact-segment in the box body.Consequently, pack into box body and to finish needed electrical connection be easy in the extreme of connector.
Because the pressure of the first terminal is applied on the contact portion, the support section structure that boss faces toward has prevented its distortion or damage.This feature has increased the reliability that connects and because thereby the first contact terminal pressure makes the contact portion bending guarantee that contact can not be lowered.
Although a special shape of the present invention that is subjected to restricted number is clearly revealed, concerning those of ordinary skill, under the prerequisite that does not depart from the scope of the present invention with spirit, the variation of structure is fine.Connector moves from connector tray and is not absolutely necessary; In the present invention, connector is once fully inserted and is locked in the appropriate location.In addition, though the strain of terminal is preferred, they do optional like this.Therefore, suitably the metallic plate of shape can be replaced.
