Description
Technical field
The present invention relates to the terminal box being attached to cable, the electric power of solar cell is supplied to the cable.
Background technology
As terminal box, there is technology as described below disclosed in Japanese Unexamined Patent Publication 2012-190838 publications：Constituting end
The housing of sub- case（It is main body in the publication）Inside, possess the terminal formed by the metal of electric conductivity, possess and protect cable
Be held in the fixture of main body, the cable is supplied to the electric power of solar module, by solder or press-fit and relative to end
The cable connection portion of son connects the cored wire of cable.
In Japanese Unexamined Patent Publication 2012-190838 publications, terminal uses board-like material, by the terminal with relative to shell
In the state of the state support of body positioning, respective position is set in the way of the cored wire of cable is abreast configured relative to terminal surface
Put relation.
The interior support terminal as Japanese Unexamined Patent Publication 2012-190838 publications in housing, by cable with fixation
Support in the mode of housing, the cored wire of the cable is press-fited and is fixed in the structure of terminal, compression during due to press-fiting by this
And effect has pressure on the phenomenon of cored wire extension, terminal.
In this wise cored wire extension phenomenon for terminal the actuating pressure on the direction along cored wire, therefore sometimes terminal from
Appropriate position departs from.For such bad, it can be considered that as described in Japanese Unexamined Patent Publication 2012-190838 publications by terminal
With the structure of the cored wire of cable by solder connection, but using solder operation compared with press-fiting operation operation it is complicated, operation is needed
Want the activity duration.
The content of the invention
Accordingly, it would be desirable to a kind of terminal box, being press-fited even if the cored wire to cable and terminal will not also act on terminal
Big pressure.
The present invention is characterized by, and is possessed：Maintaining part, housing is held in by cable, and foregoing solar module generates electricity
Electric power be supplied to the cable；Terminal board, the electric power of foregoing cable is transmitted to it；
Foregoing terminal board possesses：Be held in foregoing housing terminal body, from foregoing terminal body stretch out formed by extension,
The cored wire for the cored wire for press-fiting the cored wire of foregoing cable in the external part of foregoing extension and being electrically connected to foregoing cable press-fits
Portion, also, set from distance of the set reference plane of foregoing housing to foregoing terminal body and the distance to foregoing cored wire press-fit portion
Determine into different values, foregoing extension has the deformed region for the displacement for allowing foregoing cored wire press-fit portion.
Housing is held in terminal board in this wise and cable is supported in the state of housing by maintaining part to cored wire
When press-fit portion press-fits the cored wire of cable, the phenomenon of compression of reason when cored wire press-fits and cored wire extension, pressure acts on cored wire
Press-fit portion.In contrast, in the structure shown here, the stretching of certain length can be formed between terminal body and cored wire press-fit portion
Portion, deformed region constituted with least a portion of the extension.Also, when pressure acts on cored wire press-fit portion, deformation can be made
The part in region is deformed in the way of such as bending, can reduce the pressure directly acted on terminal body.
Therefore, a kind of terminal box is constituted, it forms the extension as deformed region function, even if so as to cable
Cored wire and terminal press-fited and will not also act on excessive pressure to terminal.
Restricted body can also be formed in foregoing housing in the present invention, the limitation body, which is overcome along foregoing cored wire, to be press-fited
The pressure of the displacement direction effect in portion and limit the displacement of foregoing terminal body.
Accordingly, terminal body is formed on the limitation body limitation of housing, therefore, it is possible to be simple structure, and even in
Cored wire press-fit portion when press-fiting from cored wire via press-fit portion actuating pressure, the displacement of terminal body is also restrained, can be by terminal
Plate is generally held in appropriate position.
Can also be in the present invention：It is and foregoing in the state of foregoing housing is installed on foregoing solar module
The bottom surface of the foregoing housing of the bearing-surface contact of solar module is foregoing set reference plane, and foregoing terminal body is configured
The position of both set a distances, and the pars intermedia for extending from foregoing terminal body towards foregoing bottom surface are being left from foregoing bottom surface
External part, form the contact conducting portion that connects with foregoing bearing-surface.
Accordingly, on the basis of the bottom wall of housing, terminal body is supported in the position that both set a distances are left from the bottom wall.Separately
Outside, it is present in from terminal body to the pars intermedia contact conducting portion with corresponding with the distance from bearing-surface to terminal body
Length is formed, and can well maintain to make conducting body of contact conducting portion and bearing-surface etc. using the elastic deformation of the pars intermedia
The state of contact.
In the present invention can also foregoing maintaining part be formed from the concave holding section of foregoing housing and that can engage
The engaging part that mode in the holding section press-fits the outer surface for being fixed on foregoing cable is constituted.
Accordingly, maintaining part is constituted by engaging part and concave holding section, so as to prevent cable to length direction
Displacement, can keep cable relative to shell stability.
