Abstract

To provide a junction box includes a base part1 having a mounting latch at each position along an edge thereof for fitting a plurality of junction part modules independently, and a bridge part. The bridge part has a mounting latch at each position in the bridge part for fitting an additional junction part module independently. The bridge part is mounted just above the junction part module fitted to the base part to complete the expansive junction box.

Description

Extendible connector junction box

The assembly of the modular electrical that can throw off after relate generally to of the present invention is used to install or fiberoptics connector.

A kind of communication case assembly of prior art has been shown in the U.S. Patent number 4878881 of Caveney etc., wherein disclosed a kind of pedestal with a plurality of connector micromodule buckles that can independently throw off, this micromodule clasp is used for fastening various connector micromodules along a lateral margin of this pedestal.The pedestal that is disclosed in this patent has a given width, so limited number connector micromodule can only be installed.Therefore need improve the technology that is used for terminal box, this terminal box can ccontaining additional connector and need not to increase the width of terminal box.

The object of the present invention is to provide a kind of connector micromodule that adds and need not to increase the terminal box of the width of terminal box.

One terminal box generally includes a pedestal, and this pedestal comprises and is used for a plurality of connector micromodules are installed to the connector micromodule erecting device that this pedestal gets on; One strides bridge plate, and this is striden bridge plate and comprises that being used for that a plurality of connector micromodules are installed to this strides the connector micromodule erecting device that bridge plate gets on and be used for striding the bridge plate tightening device with what this strode that bridge plate installs to that this pedestal gets on.

The accompanying drawing simple declaration:

Fig. 8 one is held in the part section vertical view of the connector micromodule in the terminal box pedestal.

Generally in each accompanying drawing represent that with label 10 one of enforcement notion of the present invention can expand terminal box.

Terminal box 10 comprises that a pedestal 11 and strides bridge plate 12, and each part is preferably molded by plastic monoblock.Each pedestal 11 and stride bridge plate 12 by forming along this pedestal 11 and a plurality of adjacent connector micromodule installation site 13 of striding the configuration of bridge plate 12 length, each position 13 include to be spaced and a connector micromodule are gripping into pedestal 11 or stride a fixed teeth 14 on the bridge plate 12 and the elasticity tooth 15 that links closely with independent.A blank micromodule 16 as shown in Figure 1 is used to fill the position that does not need electric or optical connector in the terminal box, here and be used to represent can be with the pedestal 11 of terminal box 10 or stride electric, the fiberoptics or the coaxial switch micromodule of any variation that bridge plate 12 links closely.Various connector micromodules and a kind of system that similarly links closely have been shown in the United States Patent (USP) 4875881, now have been incorporated into this with for referencial use.

As shown in Figure 2, stride bridge plate 12 and pedestal 11 and comprise planar miniature assembly locating surface 18.Stride bridge plate 12 and comprise that the micromodule that forms along relatively vertical limit installs feature to form a plurality of connector micromodules installation site 13 and to be configured in the end relatively and vertical with its formation bridge plate assembly wall 19 of striding of locating surface 18.Stride bridge plate assembly wall 19 and comprise the cantilever elasticity button arm 20 that is configured in the centre that in wall 19, forms by groove 21.Button arm 20 ends dispose fastening barb 22.

Pedestal 11 comprises L shaped inwall 24, this inwall 24 is connected with formation with the front portion of the sidewall 25 of pedestal 11 strides bridge plate mounting groove 26, this is striden bridge plate mounting groove 26 and is provided for accepting and holding and stride bridge plate assembly wall 19, to avoid striding bridge plate assembly wall 19 with respect to pedestal 11 motions because of carelessness makes, this motion can cause because of bridge plate 12 is striden in the micromodule insertion.As shown in Figure 4, elasticity button arm 20 outwards disposes with respect to sidewall 25, and the translation that makes wall 20 is through wall 25 and flexibly to wall 25 inside bias voltages.Be formed with on the position of each sidewall 25 a fastening groove 27 with will stride bridge plate 12 fully insert make when striding bridge plate mounting groove 26 fastening barb 22 outwards motion and close will stride bridge plate 12 with an edge joint of sidewall 25 be held on the pedestal 11.

Pedestal 11 can use separately, perhaps, as need a large amount of micromodules in terminal box, then can be held on the pedestal 11 and doubles with the quantity that enables to be installed in the micromodule 16 on the pedestal 11 striding bridge plate 12.

Be typically at first and fill pedestal 11 and stride bridge plate 12 with micromodule 16, be contained on the pedestal 11 and be configured in pedestal 11 tops and will stride bridge plate 12 and link closely by striding bridge plate 12 then, so that stride the top, connector micromodule installation site that the connector micromodule installation site 13 of bridge plate 12 directly is configured in pedestal 11 with pedestal 11.

If desired, can provide two kinds of different cover cap (not shown)s, cover or pedestal 11 is covered with striding bridge plate 12 covers for pedestal 11 is covered separately to pedestal 11.

Shown in Fig. 6-8, micromodule 16 comprises that a groove forward 28 and that is used to engage fixed teeth 14 is used for micromodule 16 and pedestal 11 or stride bridge plate 12 back of linking closely and engage the groove 29 of an elasticity fastening tooth 15.In pedestal 11, be formed with cable location wall 30, so that can in terminal box, be located to excessive cable (not shown).

More than illustrate and described concrete preferred embodiment of the present invention, for those skilled in the art, obviously can change and revise, these variations and modification all do not break away from the scope of the invention.
