Description

Testing wiring gang module for distribution frame

The utility model relates to a kind of electrical communication technology, is the test line bank module on the telephone communication machine room distributing frame, and it is the link and the test component of switch and wire jumper.

Orthorrhapha on the telephone communication machine room distributing frame is divided into safety wire connection row; play the protective effect of wiring and overcurrent, overvoltage; and the test line bank of line part; play wiring and test effect; they and alarm device, support body etc. have been formed main frame jointly; therefore be the core component on the main frame, the test line bank also can be applicable in cross-connecting box and the junction box.

The test line bank is enclosed within side by side on the steel backing frame by 8,10 or 16 modules and forms, so test line bank module is a unit of test line bank.The existing good several forms of this commercially available generic module, at home and abroad use wide, influence is big is the test line bank module that German KRONE company produces, it is by module head, module base, reed in it, the compositions such as thimble of module base rear portion and both end sides, after reed is the bending of U font, the first half of reed reverses 45 degree again, have the single deck tape-recorder seam, so after installing, the clamping face of reed front portion becomes the 45 degree angles of cut with the card joint face of module, during in the hope of card two-wire in the single deck tape-recorder seam, the equal certain tautness of tool.Facts have proved that and use single deck tape-recorder seam reed of this 45 degree angle of cut can not guarantee the balanced fastening degree of the two-wire that snaps in.This module is when the clamping switchboard cable, and the lead bunchy penetrates in the steel backing frame, through the thimble of module, connects corresponding Access Division at last respectively, and wiring exposes, and vision is messy.Need to insert a module earlier during operation on the steel backing frame and carefully connect the wire, inserting one, to connect a ground not quick.The multiple connection of switchboard cable, very not convenient.

The purpose of this utility model be to overcome design outside the deficiencies in the prior art a kind of reed can be balanced and firmly snap in two-wire, wiring influences by the steel backing frame neither, do not expose again, vision is neat, can always insert multiple connection that always connect, switchboard cable on the steel backing frame during operation and test the module of running in easily.

The purpose of this utility model can realize by following measure: it is by the module head, module base closes up into module body, reed is arranged in it, the Access Division of lead is at the forefront of module head, reed is designed to sheet always, latter half of have do the contact and play the protuberance that the booster action punching out becomes, front end has two card seams of lead, module base has 8 or 10 reed jacks, two lateral surfaces of module head respectively have 16 or 20 reed mounting grooves, two medial surfaces of module head accompany the jack of the identical testing tool connector of 8 or 10 specifications, and the both sides of module body respectively have an inner face to be furnished with the cabling frid of wire casing.

The purpose of this utility model can also be come perfect by following measure: the module head can be that tandem vertical diad unification forms; The first half of reed can be formed by stacking by bimetal leaf; Between the mounting groove of module two lateral surfaces and the reed section is arranged.

Fig. 1 is the utility model structural representation (analysing and observe) figure.

Fig. 2 is the utility model STRUCTURE DECOMPOSITION figure.

The utility model is described in detail below in conjunction with embodiment: it is closed up by the module base 6 at the module of front portion 3 and rear portion and forms, the jack 5 that eight or ten common insertions that can to hold four reeds 2 and testing tool appellation be connector are arranged in the module base, module 3 can be independent one, also can be because of the convenience of the injection moulding making and the demoulding, close up by tandem vertical diad and to be one, in full accord when remaining structure and single.The forefront of module 3 is the Access Division of lead, two medial surfaces of module accompany the jack 4 of eight or ten connectors, two lateral surfaces respectively have 16 or 20 mounting grooves 10 that are used to install tangent line sheet 1 and reed 2, have every ridge between the adjacent mounting groove, there is the location protrudingly (need not locate protruding in the groove, all with the overall dimension of tangent line sheet, reed do grooving and ridge location also can), so that tangent line sheet 1 and reed 2 location in it are installed.During installation, tangent line sheet 1 is close to the first half of mounting groove 10, and the first half of reed 2 almost occupies whole erection groove 10, is in outside the tangent line sheet 1.Obviously, as with protruding location, location, then reed 2 and tangent line sheet 1 all have separately with groove 10 in the protruding positioning hole corresponding in location, be convenient to the location.Tangent line sheet 1 is made by the rectangle sheet metal.Reed 2 is sheet always, latter half of have two to three to do the contact and play the protuberance 7 that the punching out of booster action forms, front end has two card seams of lead, for the convenience made from play booster action, the first half of reed 2 is formed by stacking by bimetal leaf, concrete manufacture craft can be understood for the colleague technical staff, does not give unnecessary details for this reason.Module 3 respectively has its inner face to be furnished with the cabling frid 9 of wire casing 8 with both sides after module base 6 closes up into module body.

If on the special-purpose lead clamping tool tangent line parts are housed, then can save tangent line sheet 1 on the module 3.But the tangent line utility frequency of component of personality card bonding tool is big, and the life-span is short, and dress tangent line sheet 1 does not just have this worry on the module head.Reed 2 first halfs also can be monolithics, and are needn't bimetallic superimposed, but complex manufacturing technology.

This test line bank module is made of the ABS engineering plastics, and the combination of each parts engages with bayonet socket.During wiring, earlier the lead of switchboard cable is penetrated in an orderly manner in each the bar wire casing 8 in the both sides cabling frid 9, wire termination places the Access Division of module 3 forefront, press special-purpose clamping tool, lead just snaps in respectively in two card seams of reed 2 front ends, tangent line sheet 1 cuts off unnecessary lead, with each reed clamping upper conductor all like this, has just finished the wiring task with quadrat method.With a specific purpose tool connector, its head is a printed circuit board during test, from jack 4 insertions at module 3 middle part, jack 5 in module base 6, the protuberance 7 of the former reed that is abutted against in twos 2 Lower Halves is separated, connect with the measurement circuit of testing tool connector respectively, play the test effect.

The advantages such as the utility model has the double card seam energy equilibrium of reed and firmly blocks two-wire compared to existing technology, and wiring is not subjected to the impact of steel backing frame, does not expose, and vision is neat, and the multiple connection of wiring operations and switchboard cable is convenient.
