Description of the Invention: [Technical Field] The present invention relates to an apparatus for electrically connecting an output terminal of a solar cell module and a terminal block of a cable to the inside of the casing body and having the casing body closed The terminal box of the cover of the opening. [Prior Art] As a terminal box configured as described above, Patent Document 1 discloses that a terminal plate (an electrode connection terminal in the literature) is provided on a bottom wall of a cartridge body (a terminal box in the literature). The lid body that closes the opening of the cartridge body is formed with a seal groove along a peripheral wall surrounding the opening of the cartridge body, and the seal groove is provided with a sealing member. Patent Document 1 discloses that a mounting portion is formed as a locking recess in a peripheral wall surrounding an opening of the cartridge body, and the lid has an engaging convex portion. According to this configuration, when the opening of the cartridge body is closed by the lid body, the engagement convex portion of the lid recessed body of the mounting portion is engaged with the lid portion, and the closed state is maintained while the sealing member and the lid body are The inner surface is in contact with it and is made into a sealed state. Moreover, the cover body is removed, whereby maintenance inspection or repair at the time of failure can be performed. Further, in Patent Document 1, it is described that in the state in which the cartridge body case passes through the cable (in the literature, the cable is connected), in the box; the body is g stomach II, thereby using the pressing from the cover body. The pressure of the part is such that the core wire of the cable is in contact with the terminal block. [Patent Document 1] [Patent Document 1] Japanese Laid-Open Patent Publication No. 2003-197944 [Draft of the Invention] [Problems to be Solved by the Invention] As described in Patent Document 1, the terminal box is made with the sun. When the inside of the battery module is in close contact with each other, it is often used. From the purpose of preventing the intrusion of rain or dust, it is necessary to have a high sealing property when the cover is closed. Moreover, in order to perform maintenance inspection or repair at the time of failure, it is necessary to have a configuration in which the cover can be disassembled. However, as described in Patent Document 1, when the lid body is completely fitted and maintained in a closed state, for example, as the temperature rises, when the pressure inside the cartridge body rises, the discharge of the internal air becomes difficult. It will cause deformation of the terminal box or cover. SUMMARY OF THE INVENTION An object of the present invention is to provide a terminal box which can discharge the internal pressure of a casing body while maintaining the sealing property of the casing body. [Means for Solving the Problem] The present invention is characterized in that the inside of the cartridge body is provided with an output terminal for electrically connecting the solar battery module and a terminal plate of the cable, and a cover for closing the opening of the cartridge body In the terminal box, a groove-shaped vent hole that reaches an opening edge of the opening from the inside of the case body is formed on an inner wall surface of the opening of the case body, and is on the inner side of the cover body -6-201230573 An annular seal member is supported on an outer circumference of the protruding portion formed to be fitted into the inside of the opening, and a holding mechanism for holding the lid in a closed position is provided, and the cover is provided by the holding mechanism In a state in which the body is held in the closed position, the sealing member and the inner wall surface of the opening are in closer contact with the bottom wall side of the case body than the vent hole, and the cover body resists the holding mechanism as the internal pressure rises. When the holding force is displaced from the opening portion toward the separating direction, the sealing member comes to a position overlapping the vent hole with the displacement, and allows the space to be vacant via the vent hole According to this configuration, when the holding mechanism holds the lid in the closed position, the sealing member supported by the lid body comes into contact with the entire circumference of the inner wall surface of the opening of the cartridge body, and exhibits good appearance. Sealed state. Further, when the lid body is held in the closed position, when the internal pressure of the cartridge body rises, the holding force of the holding mechanism is resisted, and a part or the whole of the lid body is displaced outward, and by the displacement, when the sealing material comes When the position to the vent hole is reached, the air inside the cartridge body is discharged to the outside through the vent hole. Therefore, it is possible to rationally construct a terminal box which can discharge the internal pressure of the cartridge body while maintaining the sealing property of the cartridge body. In the present invention, the opening may be formed in a rectangular shape, and the cover may have a rectangular shape having a pair of longitudinal sides and a pair of lateral sides, and the holding mechanism may include the pair of longitudinal sides and one pair of lateral sides. The vent hole is formed in the inner wall surface of the opening portion opposite to the one of the pair of longitudinal sides and the pair of lateral sides, and the pair of longitudinal sides and the pair of lateral sides are not formed. According to this, since the two sides of the rectangular cover body facing the 201230573 are held by the holding body by the holding mechanism, when the internal pressure of the case body rises, the lateral side and the longitudinal side of the cover body are allowed to be absent. The elastic deformation of the side by which the holding mechanism is held toward the outside. Thus, by elastic deformation, the discharge of the internal air is realized, and after the discharge, the cover body in the elastically deformed state returns to the original shape, whereby the sealing state of the sealing material can be maintained.

On the other end side of the terminal block 6, a conduction surface 6c through which the output cable 3 is connected by solder S is formed, and at an adjacent position, an engagement hole 6d through which the output cable 3 passes is formed and a tongue-like shape is formed. Engagement piece 6e. Further, a pair of restricting recesses 6f formed in the intermediate portion of the terminal block 6 are fitted into the aforementioned restricting piece 1j. The crimping connection portion 6a is formed by forming a U-shaped chevron shape into the core wire 4a of the cable wire 4. The wire connecting portion 6b has a pair of concave portions that engage the wire 10a at the rib-like portion described above. The conduction surface 6c forms a plane. The engaging piece 6e has a form in which a part of the sheet material is cut and stands up in an inclined posture, and by forming the engaging piece 6e, an engaging hole 6d is formed in a hole-shaped portion where the plate material is formed. The restricting recess 6f has a structure for simply cutting the end edge of the plate material. When the terminal box is connected to the output cable 3 and the cable 4, -12-201230573, the cover 2 is separated from the cartridge body 1 from the cartridge. The main body 1 is detached from the pair of terminal plates 6. In this state, the output cable 3 is inserted into the introduction port 1c of the cartridge body 1, and the end portion thereof is inserted from the upper surface side of the terminal block 6 to the engaging hole 6d, and is engaged. The engaging piece 6e is bent in the direction of the hole 6d, whereby the output cable 3 is sandwiched and held between the inner peripheral edge portion of the engaging hole 6d and the engaging piece. Further, the vicinity of the front end of the output cable 3 is connected to the conduction surface 6c fixed to the upper surface of the terminal block 6 by the solder S to be electrically connected. The cable 4 is inserted from the insertion hole Id of the cartridge body 1 in a state where the coating of the end portion of the cable 4 is removed and the core wire 4a is exposed. By performing this insertion, as shown in Fig. 4, the core wire 4a of the cable wire 4 comes into contact with the inclined surface It of the terminal block 1h, and the core wire 4a' is guided in the direction toward the opening portion 1a, and the bundle of the core wire 4a can be prevented. Inserted in a scattered (not broken) place. Then, the inserted cable 4 is pulled out, and the core 4a of the cable 4 is crimped to the portion of the terminal plate 6 where the crimping connection portion 6a is formed to form electrical conduction. As described above, the order of the operation of connecting the output cable 3 and the cable 4 to the terminal block 6 is not fixed, and any one of them may be connected first. Then, the connection output cable 3 is engaged with the terminal block 6 of the cable wire 4 in the engagement holding body Ik of the cartridge body 1 in this manner. When the engagement holding is performed, the restriction recess 6f facing the terminal plate 6 is inserted into the restriction piece 1j of the cartridge body 1 to perform positioning, and the operation of pushing in the direction toward the bottom wall 1b allows for a pair of engagement. The holding of the holding body Ik in the elastically deformed state 'and the state in which the hook portion of the engaging and holding body Ik is caught by the terminal plate 6' completes the holding of the terminal plate 6. -13- 201230573 - After the holding of the pair of terminal plates 6, the pair of wires l?a of the bypass diode 10 are set in the state of the wire connecting portions 6b of the pair of terminal plates 6, by solder S (by soldering) electrically connects a pair of wires 10a and a pair of terminal plates 6. Further, in this manner, the work of soldering the pair of wires 10a to the wire connecting portion 6b of the terminal block 6 may be performed before the terminal plate 6 is held and held by the case body 1. Further, after the terminal plate 6 is engaged and held by the cartridge body 1, the end portion of the output cable 3 is welded to the conduction surface 6 c of the terminal plate 6, after which the cartridge body 1 is closed by the cover 2 The lid body 2 is set in the manner of the opening portion la, whereby the sealing material 7 supported by the lid body 2 is in close contact with the inner wall surface of the opening portion 1c of the lid body 2 and the inner wall surface of the opening portion 1a of the cartridge body 1 to be sealed. . Then, the terminal box in this state is attached to the inside of the solar cell module or the like to complete the work.
