Embodiment

Below will combine each execution mode shown in the drawings that the utility model is described in detail.But these execution modes do not limit the utility model, and the conversion on the structure that those of ordinary skill in the art makes according to these execution modes, method or the function all is included in the protection range of the utility model.

To shown in Figure 4, the utility model one execution mode terminal box comprises box body 1, the loam cake 2 that cooperates with box body 1 and is contained in the terminal module 3 in the box body 1 like Fig. 1.

Box body 1 comprises diapire 11, upwardly extending sidewall 12 and the host cavity 15 between two side 12 from diapire 11 both sides.Diapire 11 upwards is being provided with the button gripping arm 16 that protrudes into host cavity 15 near sidewall 12 places.In this execution mode, be provided with two button gripping arms 16 near each sidewall.In addition, diapire 11 also is provided with projection 17 to make things convenient for terminal board 31 (the back literary composition is described in detail) location.With button gripping arm 16 is the boundary, and host cavity 15 is divided into first space 151 and 152, the first spaces 151, second space are the zone line of host cavity 15, in order to hold terminal board 31; Second space 152 is first space, 151 two side areas, promptly detains space between gripping arm 16 and the respective side walls 12, in second space 152, is distributed with vertically and horizontally arranged plurality of strengthening ribs 18 to strengthen the intensity of box body 1.

Terminal module 3 comprises terminal board 31, be immobilizated in the plurality of terminals 32 on the terminal board 31 and electrically connect some diodes 33 of terminals of adjacent.The both sides of terminal board 31 be provided with box body 1 in button gripping arm 16 groove 312 that interlocks and hold.In addition, also be provided with the through hole (not shown) that matches with projection 17 on the terminal board 31, to reach better locating effect.Each diode 33 comprises main part 331, be positioned at first connecting portion 332 of main part 331 1 sides and be positioned at second connecting portion 333 of main part 331 opposite sides, and in this execution mode, first, second connecting portion all is cylindric.Each terminal 32 comprises vertically the first wall 321 that extends and second wall 322 relative with first wall 321; First wall 321 is provided with slit 323 and is positioned at the location division 324 of slit 323 ends; The direction that slit 323 is extended is defined as first direction; To in vertical plane, the direction vertical be defined as second direction with first direction, location division 324 in the size on the second direction greater than the size of slit 323 on second direction.Correspondence also is provided with slit and location division on second wall 322, and this is not giving unnecessary details because structure coexists mutually.Terminal 32 is after having good positioning on the terminal board 31; First connecting portion 332 of diode 33 is put into the opening of second wall, 322 slits 323 of a terminal 32; Second connecting portion 333 of diode 33 is put into the opening of first wall 321 slits 323 of terminals of adjacent 32; Push away the main part 331 of diode 33 then through an instrument (not shown), thereby rest on location division 324 after making first, second connecting portion through slit 323.In this execution mode, greater than the size of slit 323 on second direction, so first, second connecting portion will be held in the location division 324 interfering through behind the slit 323 first, second connecting portion in the size on the second direction.
