Abstract

The invention provides a junction box including a box body, a plurality of copper plates inside the box, springs attached onto each copper plate, and a convergence band. Each copper plate includes a body portion extending horizontally, and two side walls extending upwardly from edges of the body portion and being provided with relative positioning portions. The springs each include a press portion opposite to the body portion, a pivot sleeved on the positioning portion, and a buckle portion. The convergence band is disposed between the press portion and the body portion. When the buckle portion buckles downwards the side walls, the press portion presses against the convergence band and is in surface contact with the convergence band so as to better clamp the convergence band.

Embodiment
Describe the present invention below with reference to each execution mode shown in the drawings.But these execution modes do not limit the present invention, 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 protection scope of the present invention.
As shown in Figures 1 to 4, an embodiment of the present invention terminal box comprises box body 1 and is contained in copper coin module 2 in the box body 1.
Copper coin module 2 comprises some copper coins that are arranged side by side 21, be electrically connected the diode 22 of adjacent copper coin 21 and be connected to shell fragment 23 on each copper coin 21.
Described some copper coins 21 link together by a connecting band 24, and in the present embodiment, copper coin always has four, and namely four copper coins are formed by same stamped from sheetstock bending, can guarantee that like this coplane degree of adjacent copper coin is good.Each copper coin 21 comprises the first side wall 212 that horizontally extending main part 211, autonomous body 211 1 lateral margins extend straight up and autonomous body 211 another lateral margins extend straight up and second sidewall 213 relative with the first side wall 212.Main part 211 is provided with some location holes 219 in the longitudinal direction in order to the location, in addition, main part 211 also is provided with the first depressed part 214 and the second depressed part 215, certainly, for two copper coins in the outside, only be provided with the first depressed part 214 or the second depressed part 215 on each copper coin.The first side wall 212 is provided with the first location division 216, the second sidewalls 213 that run through self and is provided with 217, the first location divisions 216, the second location division and the second location division 217 of running through self and is oppositely arranged.In addition, also be provided with the forward protuberance 210 of one extension on the two side 212,213.
Diode 22 comprises base portion 221 and the some legs 222 that extend from base portion 221 1 sides, and leg 222 quantity are two in the present embodiment.In welding process, the leg 222 of diode 22 is welded in the first depressed part 214 on the copper coin 21, diode 22 base portions 221 are welded in the second depressed part 215 of adjacent copper coin 21, and diode 22 is well located, convenient welding.In addition, also be provided with upwardly extending retaining wall 218 in the second depressed part 215 both sides, further prevent diode 22 skews, certainly, also retaining wall can be set around the first depressed part 214.Adjacent diode 22 dislocation arrange convenient heat radiation.
Shell fragment 23 is installed on the copper coin 21 with clamping convergent belt (not shown), shell fragment 23 is formed by metal material punching press bending, and the connecting portion 232 that comprises horizontally extending pressure section 231, tilts to extend at an angle with pressure section 231, the pivot 233 that is connected connecting portion 232 and pressure section 231 reach from the holding part 234 of connecting portion 232 away from the oblique downward-extension of an end of pivot 233.Pivot 233 1 ends are enclosed within the first location division 216, and the other end is enclosed within the second location division 217, so can realize the Primary Location of shell fragment 23.At this moment, pressure section 231 is relative with main part 211.The terminal both sides of holding part 234 are provided with lock part 235.In actual mechanical process, at first the pivot 233 with shell fragment 23 is enclosed within the first location division 216 and the second location division 217, then convergent belt is put between main part 211 and the pressure section 231, press down at last holding part 234, make holding part 234 and sidewall clasp, particularly, lock part 235 is supported below protuberance 210 and realize snap close.Press down at holding part 234 and will drive pressure section 231 in the process and clamp convergent belts downwards and prevent that it from coming off.Because pressure section 231 be arranged in parallel with convergent belt, for the face contact, can reach better clamping effect between the two.In order to make pivot 233 be inserted in easily first, second location division 216,217, in the course of processing, first, second location division size is generally greater than the size of pivot 233, in the process that presses down holding part 234, pivot 233 can be upwards mobile in first, second location division, thereby cause pressure section 231 and convergent belt not parallel.In order to guarantee face contact between the two, the end of pressure section 231 is provided with the flat part 236 that upwarps, and flat part 236 will contact with convergent belt realization face like this.Because pressure section 231 remains that with convergent belt face contacts, and can more firmly clamp convergent belt.
When needing welding diode 22, at first the copper coin 21 that links together is retained on a tool (not shown) by the location hole 219 on the main part 211, then successively at adjacent copper coin welding diode 22, determine after the firm welding copper coin module 2 packed in 1 box body, at last the Partial Shear of connecting band 24 between adjacent copper coin 21 fallen.
The pressure section of shell fragment of the present invention contacts with the zone face that confluxes, and can better clamp convergent belt.
Be to be understood that, although this specification is described according to execution mode, but be not that each execution mode only comprises an independently technical scheme, this narrating mode of specification only is for clarity sake, those skilled in the art should make specification as a whole, technical scheme in each execution mode also can through appropriate combination, form other execution modes that it will be appreciated by those skilled in the art that.
Above listed a series of detailed description only is specifying for feasibility execution mode of the present invention; they are not to limit protection scope of the present invention, allly do not break away from equivalent execution mode or the change that skill spirit of the present invention does and all should be included within protection scope of the present invention.
