Embodiment
Below with reference to each execution mode shown in the drawings, describe the present invention.But these execution modes do not limit the present invention, the conversion on the structure that those of ordinary skill in the art makes according to these execution modes, method or function all is included in protection scope of the present invention.
As shown in Figures 1 and 2, an embodiment of the present invention terminal box comprises box body 1, is contained in the terminal module 2 in box body 1 and the upper cover 3 coordinated with box body.
As shown in Figure 2, box body 1 comprises the host cavity 15 that diapire 11, the antetheca 13 from the diapire 11 upwardly extending sidewalls 12 in both sides, connection two side 12 reach between two side 12.Diapire 11 upwards is being provided with near sidewall 12 places the clasp arm 16 that protrudes into host cavity 15.In the present embodiment, be provided with two clasp arms 16 near each sidewall.In addition, diapire 11 also is provided with projection 17 to facilitate terminal board 21(hereinafter to describe in detail) location.Take clasp arm 16 as boundary, and host cavity 15 is divided into the zone line that the first space 151 and second space 152, the first spaces 151 are host cavity 15, in order to hold terminal board 21; Second space 152 is the first space 151 two side areas, and space between clasp arm 16 and respective side walls 12 is distributed with vertically and horizontally arranged some reinforcements 18 to strengthen the intensity of box body 1 in second space 152.Antetheca 13 is provided with the through hole 14 that runs through himself, and this through hole 14 extends into box body 1 inside for external cable (not shown).
As shown in Fig. 2, Fig. 3, Fig. 4 A, Fig. 4 B, Fig. 4 C, terminal module 2 comprises terminal board 21, be immobilizated in the some terminals 22 on terminal board 21 and be electrically connected some diodes 24 of terminals of adjacent.The both sides of terminal board 21 be provided with box body 1 in the groove 212 of clasp arm 16 phase clasps, front side is provided with the passage corresponding with through hole 14 213.In addition, also be provided with the hole (not shown) matched with projection 17 on terminal board 21, to reach better locating effect.In the present embodiment, the number of terminal 22 is 4, is followed successively by the first terminal 221, the second terminal 222, the 3rd terminal 223 and the 4th terminal 224.Wherein, the first terminal 221 and the 4th terminal 224 are outer terminal, and these two each fixings of outer terminal end have a shell fragment 4.Shell fragment 4 comprises connected successively holding part 41, connecting portion 42 and insertion section 43, there is opening 411 on holding part 41, insertion section 43 is stretched in opening 411 and is offseted with opening lateral margin 412, and the end of insertion section 43 is provided with kink 44 and breaks away from opening 411 to prevent insertion section 43.The first terminal 221 of below take illustrates as example, the first terminal 221 comprises the support portion 226 that extension 225 reaches through shell fragment opening 411, described support portion 226 is to reflexed again after a lateral buckling certain angle, thereby form a projection 227 on support portion 226, the part of support portion 226 above projection 227 is defined as support division 228, and the part of protruding 226 belows is defined as free section 229.
When the first terminal 221 assembles with shell fragment 4, compressing 43Shi insertion section 43, insertion section moves towards connecting portion 42, form like this space between opening lateral margin 412 and insertion section 43, opening 411 is passed by this space in the support portion 226 of the first terminal 221, then discharge insertion section 43, by the elastic force effect, support portion 226 is sandwiched between opening lateral margin 412 and insertion section 43, particularly, support division 228 offsets with opening lateral margin 412, kink 44 is contained in the recess 230 at protruding 227 back sides, thereby prevents shell fragment 4 and the first terminal 221 accidental.
In the present embodiment, terminal board 21 separates with box body 1, certainly terminal board 21 also can with box body 1 integrated injection molding, thereby become the part of box body 1.The present invention, by the restoring force of shell fragment, makes cable clamping between opening lateral margin and support portion, easy to operate and clamp firmly.
Be to be understood that, although this specification is described according to execution mode, but not each execution mode only comprises an independently technical scheme, this narrating mode of specification is only 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 is only illustrating for feasibility execution mode of the present invention; they are not in order to limit the scope of the invention, all disengaging within equivalent execution mode that skill spirit of the present invention does or change all should be included in protection scope of the present invention.
