Description

Tester of telephone general wiring support

The utility model relates to a kind of monitor device that is used for the telephone exchange interswitch board line, specifically, is the tester that is used on the telephone main frame.

Tester is a critical component on the telephone main frame, and its is for circuit test and loop line test, subscriber jumper, accommodates the usefulness of trunk line and the contact of special line signal.At present, widely used tester on standard switch main frame in length and breadth has two kinds of 20 loop line formula testers and 100 loop line pin testers.20 loop line formula testers are used existing more than 50 year till today, 197 millimeters of every block lengths, wide 93 millimeters, dark 40 millimeters, and relatively heavier, amount of copper consuming is big, adopts welding manner.100 loop line pin testers are the new products that use recent years, 193 millimeters of every block lengths, wide 118 millimeters, dark 116 millimeters, capacity is big, and the employing wrapping system, these compare preceding going a step further with 20 loop line formula testers, its shortcoming is from the inlet wire of the telephone exchange back side at tester, make troubles for maintenance and increase-volume, when tester close-up row, must interrupt adjacent telephone channel and just can safeguard, install, operate especially; In addition, when test operation, to plug the test stopper, many one operation sequences.The German Krone formula tester that is used for program control standard telephone exchange main frame, adopt modular structure, the front inlet wire, every module is 10 loop lines, uses the snap fit wiring, replace the test stopper with the reed contact, more satisfactory, but it can not solderless wrapped connection, during the multiple line clamping, require to use the lead of same line footpath size, module size can not with existing standard telephone main frame tester size compatibility in length and breadth.

The purpose of this utility model provides a kind of universal, easy to operate modular telephone main frame tester.

Fig. 1 is a structural representation of the present utility model, and wherein (a) is front view, (b) is vertical view, (c) is end view.

Fig. 2 and 3 is two kinds of structural representations of binding post 3 and contact spring 4.

Fig. 4 is that the another kind of top base 1 and bottom base 2 connects schematic diagram.

Technical solution of the present utility model is as follows:

Adopt modular structure, divide 5,8 and 10 loop lines three kinds of test modules.Each test module comprises top base 1, bottom base 2, binding post 3, contact spring 4, installation seat plate 5, inserted sheet 6 and test inserted sheet 7 open circuit.Top base 1 and bottom base 2 are made by flame retardant plastics, and they become tight mechanical connection.Respectively there is turnover line groove 8 both sides of bottom base 2, in order to lay the turnover telephone wire.Binding post 3 is in aggregates with contact spring 4, curve the cocurrent and parallel structure, be fixed in the placed hole 9 of top base 1, binding post 3 exposes the front surface of top base 1, is the flat square column or the top that are suitable for solderless wrapped connection and becomes three bifurcateds to be suitable for clamping, contact spring 4 then is hidden in the inside of top base 1, each loop line has corresponding four binding posts 3, is divided into two rows, and central authorities are jack 10, be used for inserting open circuit inserted sheet 6 or test inserted sheet 7, what respectively there was a breach both sides advances wire hole 11.Respectively there is a threading opening 12 at the two ends of bottom base 2.Lay 2 one-tenth tight mechanical connections of seat board 5 and bottom base, the shared installation seat plate 5 of tester.The inserted sheet 6 that opens circuit is an insulating trip, inserts jack 10 to cut off words line path; And test inserted sheet 7 is sheet patchplugs, inserts jack 10 to obtain test signal.

The utility model has the advantages that: 1. wiring can be adopted solderless wrapped connection or clamping; 2. adopt the reed contact, lacked the operation sequence of plug test stopper than the pin tester; 3. inlet wire, wire jumper and line service are all carried out in the front of top base 1, and be more convenient; 4. change telephone wire or increase-volume operation and do not influence adjacent other telephone channel; 5. adopt the modular combination, can be as required, the telephone door of flexible combination tester is counted capacity; 6. wire jumper can multiple connection, and the line footpath can be inequality; 7. existing concentrated through wires hole also has the through wires hole of every loop line, is easy for installation and maintenance.

Provide embodiment of the present utility model below.

Example 1 according to Fig. 1 and Fig. 3,4, provides an embodiment of the present utility model.Fig. 1 is the telephone main frame tester that is made of 10 test modules, and each test module has 10 loop lines, and promptly this tester has 100 call gate capacity.The overall dimension of tester is: wide=20 millimeter * 10=200 millimeter, and long=140 millimeters, dark=63 millimeters, the wide of each test module is 18 millimeters, long 140 millimeters, dark 63 millimeters, adjacent block is spaced apart 2 millimeters.Each test module comprises top base 1, bottom base 2, binding post 3, contact spring 4, the inserted sheet 6 that opens circuit, test inserted sheet 7, and installation seat plate 5.Top base 1 and bottom base 2 all adopt the PBS flame retardant plastics, are tightly connect by the screw 13 that is positioned at two ends between them.Respectively there is a threading opening 12 at the positive two ends of bottom base 2; In the front of top base 1 10 call gate loop line pieces are arranged, with vertical arrangement, what each loop line piece had 9 two breach of 4 binding posts, 4,4 placed holes of 3,4 contact springs advances wire hole 11 and a jack 10.Jack 10 is positioned at the central authorities of loop line piece, and its both sides are wire holes 11 into, and its upper and lower respectively has two binding posts 3; The top of binding post 3 is three forkeds, is suitable for the usefulness of not collinear footpath multiple connection, and contact spring 4 is positioned at the inside of top base 1.During assembling, top base 1 is connected with bottom base 2 usefulness screws 13 after earlier binding post 3 and contact spring 4 being placed, respectively there is a turnover line groove 8 both sides of bottom base 2 again, and respectively there is a threading opening 12 at its positive two ends.In Fig. 3, provide the structure of binding post 3 and contact spring 4, they are that 0.8 millimeter tin-phosphor bronze constitutes by thickness, binding post 3 is folded into cocurrent and parallel association with contact spring 4.

As the conversion of present embodiment, binding post 3 is the flat square column, is suitable for the wrapping system wiring.

As another conversion of the foregoing description, connect with the hasp among Fig. 4 14 between top base 1 and the bottom base 2.

As the another kind of again conversion of present embodiment, binding post 3 adopts integrative-structure mode shown in Figure 2 with contact spring 4, promptly connects at root, short pin bending upwarps, the length pin cocurrent and parallel conjoined structure that long pin stretches, short pin is a contact spring 4, long pin is a binding post 3.

Example 2, according to the frame mode of Fig. 1～4, the test module of 8 loop line capacity of formation and example 1 same structure more on demand, is assembled into tester with plurality of modules.The difference of their examples 1 only is that the length of each test module is 114 millimeters.

Example 3, according to the frame mode of Fig. 1～4, the test module of 5 loop line capacity of formation and example 1 same structure more on demand, is assembled into tester with plurality of modules.The difference of it and example 1 only is that the length of each test module is 75 millimeters.

As the conversion of above-mentioned three embodiment, the overall dimension of test module is by above-mentioned size increase and decrease about 30%.Promptly a.10 loop module is long=182～98 millimeters, and is dark=82～44 millimeters, wide=23～13 millimeter; B.8 loop module is long=148～79 millimeters, and is dark=82～44 millimeters, wide=23～13 millimeter; C.5 loop module is long=98～52 millimeters, and is dark=82～44 millimeters, wide=23～13 millimeter.
