Ozadje izumaBACKGROUND OF THE INVENTION

Področje izumaFIELD OF THE INVENTION

Izum se nanaša na orodje za istočasno vtiskanje več izoliranih žic v električni konektor.The invention relates to a tool for simultaneously plugging multiple insulated wires into an electrical connector.

Stanje tehnikeThe state of the art

Zlasti v telekomunikacijski industriji so znani električni konektoiji, ki so predvideni za sprejem več izoliranih žic, da zaključijo več električnih kontaktov. Nadalje je znana izvedba povezave v teh konektoijih, ki je predvidena s kakor črka U oblikovanimi izolacijo odstranjujočimi kontakti, v katere so vtisnjene žice. Izolacijo odstranjujoči kontakti so locirani v pridržalnem delu, v katerega so posamično vstavljene žice. Pritisni del ah pokrov sodeluje s pridržalnim delom, da pritisne posamezne žice istočasno v kakor črka U oblikovane izolacijo odstranjujoče kontakte.Particularly in the telecommunications industry, electrical connectors are known, which are designed to receive multiple insulated wires to complete multiple electrical contacts. It is further known to provide the connection in these connectors, which is provided as U-shaped insulating removable contacts into which the wires are imprinted. Insulation stripping contacts are located in the retaining part into which the wires are individually inserted. The press part ah cover cooperates with the retainer part to press the individual wires at the same time as the letter U shaped insulation removing contacts.

Taki konektoiji so npr. opisani v nemškem patentnem spisu DE 39 20 367.Such connexions are e.g. described in German patent file DE 39 20 367.

Nadalje je znana izvedba takih konektoijev v spojni glavi, ki predvideva poenostavljeno vstavitev žic v konektoije. Sele tedaj, ko so vse žice vstavljene in fiksirane, pritisnejo v kontaktne elemente pridržalnega dela s pomočjo pritisnega dela. Običajno je ta postopek izveden s pomočjo ustreznega kleščam podobnega orodja, ki je npr. znano iz nemškega patentnega spisa DE 25 15 171. Znano orodje vsebuje kraka, ki obdajata spojno glavo na nasprotnih straneh in sta z njo tudi povezana. Pritisni člen je lociran med ročici in se lahko premika s pomočjo ročnega vzvoda in prenosa zato, da pritisne več žic v pridržalni del, v katerem so žice tudi istočasno odsekane. V tem orodju ustvagajo pritisno silo mehanično in jo tudi mehanično prenašajo. Iz evropske patentne prijave EP 0 179 112 je tudi znano izvajanje pritisne sile s pomočjo hidravhčnega prenosnega sredstva.It is further known that such connectors are provided in the coupling head, which provides for simplified insertion of wires into the connectors. Only when all the wires are inserted and fixed are they pressed into the contact elements of the retaining part by means of a pressure part. Typically, this process is performed using a suitable pliers-like tool, e.g. known from German patent file DE 25 15 171. A known tool comprises arms that surround the connecting head on opposite sides and are connected thereto. The push link is located between the levers and can be moved by hand lever and transmission to push more wires into the retaining part, in which the wires are also cut off at the same time. In this tool, they apply mechanical force to the compression force and also carry it mechanically. EP 0 179 112 also discloses the application of compression force by means of a hydraulic transmission means.

Znana je tudi izvedba znanih konektogev z vtičnimi kontakti in vtičnimi kontaktnimi trakovi. Nadalje je znano tudi skladanje dveh ali več konektogev enega na drugega. V ta namen imajo različne kombinacije konektogev različne višine. Zato je potrebno upoštevati višino različnih konektogev, ko pritisnejo in vtisnejo žice. Pri hidravlično delujočih orodjih dosežejo to z ustrezno hidravlično krmiljenim orodjem. Taka orodja pa so sorazmerno težka in tudi sorazmerno zahtevna za rokovanje. Pri ročnih orodjih je zaželena manjša teža in je običajno potrebno za vsako višino konektoga drugo orodje.Also known is the implementation of known connectogens with plug contacts and plug contact strips. It is further known to stack two or more connectogens one on top of the other. For this purpose, different combinations of connectogues have different heights. Therefore, it is necessary to take into account the height of the various connectogens when pressing and inserting the wires. For hydraulically operated tools, this is accomplished with suitable hydraulically controlled tools. Such tools, however, are relatively heavy and also relatively difficult to handle. For hand tools, less weight is desired and a different tool is usually required for each height of the connector.

Povzetek izumaSummary of the Invention

Izum se nanaša na orodje, pri katerem so izolirane žice pritisnjene v konektoge različnih višin.The invention relates to a tool in which insulated wires are pressed into connectors of different heights.

V orodju po izumu je pritisni člen prirejen tako, da se odmakne za vnaprej določen odmik glede na spojno glavo neodvisno od prenosnega sredstva. Delovanje ročnega vzvoda vodi do odmika pritisnega člena glede na spojno glavo. Ta odmik pa ne more biti uporabljen za prireditev višine konektoga, ker je vnaprej določen hod potreben za pritisk vstavljenih žic popolnoma v kontakte. Na koncu takega hoda so predvideni omejilni elementi ali druga sredstva za preprečitev nadaljnjega odmika od pritisnega člena. Z orodjem po izumu je predvidena tudi taka omejitev hoda z nastavitvijo lege pritisnega člena predno prične hod z različnih začetnih leg, ki so prirejene dejanski višini vsakokratno uporabljenega konektoga.In the tool according to the invention, the pressure member is arranged to move by a predetermined offset relative to the coupling head, independent of the transmission means. The operation of the hand lever leads to a displacement of the pressure member relative to the coupling head. However, this offset cannot be used to adjust the height of the connector, since a predetermined stroke is required to press the inserted wires completely into the contacts. At the end of such a stroke, limiting elements or other means are provided to prevent further deviation from the pressure member. The tool according to the invention also provides for such a stroke restriction by adjusting the position of the pressure member before starting the stroke from the various starting positions, which are adapted to the actual height of the connector used in each case.

Za dosego odmika od pritisnega člena korak po koraku so izvedene različne izvedbe. Prvi izvedbeni primer po izumu predvideva, da je najmanj vmesni člen povezan z zadnjo stranjo pritisnega člena, ki je vrtljiv na osi. V različnih legah sodeluje vmesni člen s prenosnim vzvodom, ki deluje preko ročnega vzvoda, s pritisnim členom, ki ima različno oddaljenost od prenosnega vzvoda v posamičnih zasukljivih legah vmesnga člena. Vmesni člen je lahko npr. nameščen na ekscentričnem členu. Na ekscentrični člen lahko delujemo eksterno, npr. z vzvodom in npr. ustvari dve legi pritisnega člena. Po drugem izvedbenem primeru po izumu ima vmesni člen več žlebov na obodu, pri čemer lahko čep, ki je nameščen na prenosnem vVarious embodiments are made step by step to achieve a deviation from the pressure member. The first embodiment of the invention provides that at least the intermediate member is connected to the rear of the pressure member which rotates on the axis. In different positions, the intermediate member cooperates with a transmission lever acting via a manual lever, with a pressure member having a different distance from the transmission lever in the individual rotary positions of the intermediate member. The intermediate link may be e.g. mounted on an eccentric member. We can act externally on the eccentric link, e.g. with lever and e.g. creates two positions of the pressure member. According to another embodiment of the invention, the intermediate member has several grooves on the circumference, the pin being mounted on the portable in

vzvodu, vprijemlje v žlebove, ki so različno oddaljeni od vrtilne osi vmesnega člena. Število odmičnih korakov pritisnega člena ustreza številu žlebov. Slednji izvedbeni primer je delno primeren za orodja, ki dosegajo nedvoumne fiksne lege glede na spojno glavo, t.j., da ne morejo biti odmaknjeni glede na spojno glavo.lever grips into grooves that are differently spaced from the pivot axis of the intermediate member. The number of recessing steps of the pressure member corresponds to the number of grooves. The latter embodiment is partially suitable for tools that reach unambiguous fixed positions with respect to the coupling head, i.e. they cannot be offset with respect to the coupling head.

Po naslednjem izvedbenem primeru po izumu ima spojna glava zobe na nasprotnih straneh, orodje ima zasukljivo podprta vzvoda, ki imata tudi zob, ki sodeluje z zobmi spojne glave. Korak zob je lahko izbran tako, da ustreza razmik med dvema sosednjima zobovoma razliki višine dveh različnih konektogev. Za konektorsko kombinacijo med temi vrednostmi višin lahko dosegamo prilagoditev z odmikom pritisnega člena, t.j. z opisanim ekscentričnim členom.According to another embodiment of the invention, the connecting head has teeth on opposite sides, the tool has rotatably supported levers, which also have a tooth that cooperates with the teeth of the connecting head. The tooth pitch can be selected to match the spacing of two adjacent teeth to the difference in height of two different connectogues. For the connector combination between these height values, adjustment can be achieved by offsetting the pressure member, i.e. with the eccentric term described.

Podroben opis risbDetailed description of the drawings

Orodje 10, kije prikazano na sl. 1 vsebuje ohišje 12, kije predstavljeno delno odprto. Prvi vzvod 14 je nepremično nameščen na ohišju, medtem ko je drugi delovni vzvod 16 povezan z ohišjem 12 v 18. Na nasprotnem koncu ohišja sta predvidena vzporedno v razmiku potekajoča podaljška 20, 22, ki sodelujeta s spojno glavo, označeno pri 24. Prislonska plošča 26 ah oporni člen spojne glave 24 je prikazan tako, da je vanj možno vstaviti električni konektor, ki ni prikazan. Plošča 26 ima žlebova 28, 30 na nasprotnih koncih in v katera vprijemljeta spodnja kraka 32, 34 vzvodov 36, 38 s pomočjo somikov 40, 42, da spojita orodje 10 s spojno glavo 24. Kot je posebej prikazano na sl. 1 A na desni strani sl. 1, sta žlebova 28, 30 oblikovana kot vihčasta dela plošče 26; somika 40, 42 sta predvidena na nasprotnih straneh vzvodnih ročic 32, 34. Vzvoda 36, 38 sta zasukljivo nameščena na ohišju 12 in sta nagnjena v smeri, oziroma nasprotni smeri gibanja urnega kazalca, kot je prikazano na desni strani sl. 1, da vprijemljeta ah izstopata iz žlebov 28, 30, s tem, da sta vzvoda' 36, 38 nagnjena s pomočjo vzmeti 44, 46 proti zaklepni smeri. Podolgovati pritisni člen 50, ki se razprostira približno vzporedno s prislonsko ploščo 26, je povezan z dvema, kot krožni odsek oblikovanima vmesnima členoma 56, 58 v 52, 54. Vmesni člen 56, 58 je lahko zasukan s štirirobnikom 60, 62 npr. z ustreznim orodjem tako, da lahko vprijemljejo razilični žlebovi 64, 68 na obodu vmesnega člena 56, 58 s čepoma 70, 72 veznih elementov 74, 76. Vezna elementa 74, 76 povezujeta prenosnik, vkjučno z zobato letvijo 82 v 78, 80, ki je premično podprt v ohišju 12 vzporedno s pritisnim členom 50. Vzvoda 74, 76 sta nadalje povezana z enim vzvodom 84, ki je povezan s pritisnim členom 50 s pomočjo vzmeti 86.Tool 10, shown in FIG. 1 contains a housing 12, which is partially open-open. The first lever 14 is fixedly mounted on the housing, while the second operating lever 16 is connected to the housing 12 in 18. At the opposite end of the housing, parallel extensions 20, 22 are provided in parallel, which cooperate with the coupling head indicated at 24. Support plate 26 ah the support member of the coupling head 24 is shown such that it is possible to insert an electrical connector which is not shown. The plate 26 has grooves 28, 30 at opposite ends and into which the lower arms 32, 34 of the levers 36, 38 are secured by means of catches 40, 42 to connect the tool 10 with the coupling head 24. As shown in FIG. 1 A to the right of FIG. 1, the grooves 28, 30 are formed as swivel portions of panel 26; somics 40, 42 are provided on opposite sides of the levers 32, 34. The levers 36, 38 are pivotally mounted on the housing 12 and are inclined in the opposite or counter-clockwise direction, as shown on the right side of FIG. 1, that the grips ah protrude from the grooves 28, 30, with the levers 36, 38 being tilted by means of a spring 44, 46 towards the locking direction. The elongate pressure member 50, which extends approximately parallel to the stop plate 26, is connected to two circular sections formed by intermediate members 56, 58 into 52, 54. Intermediate article 56, 58 may be rotated by a quadrilateral 60, 62 e.g. with suitable tools so that different grooves 64, 68 at the circumference of the intermediate member 56, 58 can be gripped by studs 70, 72 of the connecting elements 74, 76. The connecting elements 74, 76 connect the gearbox, including the toothed rack 82 to 78, 80, which is movably supported in the housing 12 in parallel with the pressure member 50. The levers 74, 76 are further connected to one lever 84 which is connected to the pressure member 50 by means of a spring 86.

Zobata letev 82 je pomična vzporedno s pritisnim členom z zobatim vzvodom 88, ki ima ozobljen konec, kije povezan z delovnim vzvodom 16. Vzmetno nagnjen zaklepni vzvod 90 ima tudi zobe, ki vprijemljejo z zobmi na zobati letvi 82 v vsaki legi. Z opisanim mehanizmom je lahko pritisni člen pomikan proti prislonski plošči 26 za vnaprej določeno dolžino hoda tako, da je konektor na prislonski plošči 26 pritisnjen z vnaprej določeno vrednosljo za vriskanje žice na zgoraj opisani način.The toothed rack 82 is movable parallel to the press member with the toothed lever 88 having a toothed end that is connected to the lever 16. The tilting lever 90 also has teeth that engage with the teeth on the toothed rack 82 in each position. With the mechanism described, the push member can be moved toward the stop plate 26 for a predetermined stroke length so that the connector on the stop plate 26 is pressed with a predetermined value for screaming the wire as described above.

Kot bo videti, imajo posamezni žlebovi 64, 68, ki so označeni z a, b, c in d na kakor krožni lok oblikovanem vmesnem členu, različen odmik od rotacijske osi 52, 54 vmesnega člena 56, 58. Zato ima pritisni člen 50 različno začetno lego, ko izvaja opisan hod v odvisnosti od žlebov 64, 68, v katere vprijemlje čep 70, 72 vzvoda 74, 76. Na ta način je dosežena nastavitev višine konektoga.As will be seen, the individual grooves 64, 68, which are marked by, b, c and d in the circular arc of the formed intermediate member, have a different distance from the rotary axis 52, 54 of the intermediate article 56, 58. Therefore, the pressure member 50 has a different initial position when it performs the described stroke depending on the grooves 64, 68, into which the plug 70, 72 lever 74, 76 receives. In this way, the height adjustment of the connector is achieved.

Pri opisanem vriskanju naredi pritisni člen 50 vnaprej določen hod, medtem ko dosežemo npr. omejitev hoda z omejilnikom, ki sodeluje z zobato letvijo 82. Ko je vriskanje končano, deluje omejilni vzvod 90 tako, da je zobata letev 82 povrnjena s potiskom vzmeti v lego, ki je prikazana na sl. 1. Za odstranitev konektoga sta vzvoda 36, 38 nagnjena tako, daje lahko orodje 10 odstranjeno s spojne glave 24. Nato lahko odstranimo konektor s spojne glave 24.In the described screaming, the pressure member 50 makes a predetermined stroke, while e.g. restriction of travel with a limiter that cooperates with the toothed rack 82. When the screaming is complete, the limiting lever 90 operates in such a way that the toothed rack 82 is restored by pushing the spring into the position shown in FIG. 1. To remove the connector, the levers 36, 38 are tilted so that the tool 10 can be removed from the coupling head 24. The connector can then be removed from the coupling head 24.

Orodje 100, kije prikazano na sl. 2, vključuje ohišje 102, delovni vzvod 104, kije fiksno nameščen na ohišju 102, medtem ko je naslednji delovni vzvod 106 povezan z ohišjem 102 v 108. Ohišje 102 je prikazano delno odprto, da je jasneje viden prenosni mehanizem.The tool 100 shown in FIG. 2, includes a housing 102, a working lever 104 which is fixedly mounted on the housing 102, while the next operating lever 106 is connected to the housing 102 in 108. The housing 102 is shown partially open to make the transmission mechanism clearer.

Spojna glava 110 ima prislonski člen v obliki sprejemne plošče 112 za sprejem konektoga, ki ni prikazan. Na nasprotnih straneh spojne glave 110 sta izvedem zobati letvi, ki imata vzporedne zobe 114, 116. Vzvoda 122, 124 sta povezana na nasprotnih straneh ohišja 102 v 118, '120. En krak vzvodov 122, 124 določa ročico 126, 128, medtem ko je drugi krak 130, 132 tudi predviden z zobmi, ki vprijemljejo z zobmi 114, 116 spojne glave 110. V skladu s korakom zob 114, 116 ah 130, 132 je lahko nastavljen vnaprej določen prostor h pritisnega člena 143 od zgornje strani sprejemne plošče 112.The connecting head 110 has a stop member in the form of a receiving plate 112 for receiving a connector that is not shown. On the opposite sides of the coupling head 110, there are two toothed laths having parallel teeth 114, 116. The levers 122, 124 are connected on opposite sides of the housing 102 in 118, '120. One arm of the levers 122, 124 defines a lever 126, 128, while the other arm 130, 132 is also provided with teeth that engage the teeth 114, 116 of the connecting head 110. According to the tooth step 114, 116 ah 130, 132, the predetermined space h of the pressing member 143 from the upper side of the receiving plate 112 is set.

Kot je videti na sl. 3 in 4, je pritisni člen 134 oblikovan kot črka U v prečnem preseku in povezan z ohišjem 102 s pomočjo ekscentričnega somika 136. Mimogrede, ohišje vsebuje dve nasprotni plošči 138, 140. Na enem končuje ekscentrični somik 136 povezan z ročnim vzvodom 142, tako da je razmik h lahko spremeniti z nagibom vzvoda 142. Ekscentrični somik 136 ima podaljšek 144, kije povezan s prestavnim členom 148 v 146 (glej sl. 2), pri čemer je prestavni člen 148 vrtljivo uležajen v ohišju 102 v 150. Prestavni člen vsebuje čep 152, ki sodeluje z izsekom 154 ohišja 102, kije označen s prekinjenima črtama.As shown in FIG. 3 and 4, the pressure member 134 is shaped like a letter U in cross section and connected to the housing 102 by means of an eccentric som 136. By the way, the housing contains two opposite plates 138, 140. At one end, the eccentric som 136 is connected to a hand lever 142, thus that the distance h is adjustable by the tilt of the lever 142. The eccentric catfish 136 has an extension 144 which is connected to the gear member 148 in 146 (see FIG. 2), the gear member 148 being rotatably mounted in the housing 102 in 150. The gear member comprises a plug 152 that cooperates with a section 154 of a housing 102 marked with broken lines.

Prenosnik za pritisni člen 134 proti plošči 112 vključuje zobati vzvod 156, kije povezan z delovnim vzvodom 106 tako, da privede delovanje vzvoda 106 do sukanja prenosnega člena 148 v smeri urnega kazalca. Vzmetno nagnjen zaklepni vzvod 158 varuje lego prenosnega člena 148. Po sukanju prenosnega člena 148 je pritisi člen 134 premaknjen navzdol, da ustvari silo na konektor na sprejemni plošči 112. Dolžina hoda pritisnega člena 134 je omejena z dolžino loka prenosnega člena 148.The push-pull member 134 against the plate 112 includes a gear lever 156, which is connected to the work lever 106 in such a way that the lever 106 acts in a clockwise rotation of the transfer member 148. A spring-tilted locking lever 158 protects the position of the transfer member 148. After rotation of the transfer member 148, the press member 134 is moved down to create force on the connector on the receiving plate 112. The travel stroke of the press member 134 is limited by the arc length of the transfer article 148.

Na sl. 5 do 8 je prikazano orodje 100 v povezavi s konektoiji vi do v4 različnih višin, ki so nameščeni v spojni glavi 110. Konektorja vi in v2 s sl. 6 in 7 imata razliko višin npr. 6 mm. Razlika višin med konektoijema v3 in v4 s sl. 7 in 8 znaša npr. do 1, 3 mm Kot je videti na sl. 5 in 6, oziroma na sl. 7 in 8, ustvari nagib ročnega vzvoda 142 in s tem sukanje ekscentričnega somika 135 za okoli 180° odmik od pritisnega člena 134 za okoli 1,3 mm. Razmik med pritisnim členom 134 in ploščo 112 na sl. 5 in 6 znaša 10,1 in 11,4 mm oziroma na sl. 7 in 8 znaša 16,1 in 17,4 mm. V položajih po sl. 5 in 6 vprijemlja ozobje vzvodov 122, 124 najnižje področje zob 114, 116 spojne glave 110, V položajih s sl. 7 in 8 je vprijemanje premaknjeno navzgor za korak enega zoba. To ustreza spremembi razmika med pritisnim členom 134 in ploščo 112 za 6 mm. Če je vzvod 142 na sl. 7 nagnjen za 180° v skladu s sl. 8, je pritisni člen 134 znižan za okob 1,3 mm. Zniževanje pritisnega člena se začne od spremenjene lege, kije okob 6 mm višja od tiste na sl. 5 in 6.In FIG. 5 to 8, the tool 100 is shown in connection with the connectors vi to v4 of different heights, which are located in the coupling head 110. The connectors vi and v2 of FIG. 6 and 7 have a height difference of e.g. 6 mm. The difference in heights between the connectors v3 and v4 of FIG. 7 and 8, e.g. to 1, 3 mm As shown in FIG. 5 and 6, respectively. 7 and 8, create a tilt of the hand lever 142 and thereby rotate the eccentric snap 135 by about 180 ° offset from the pressure member 134 by about 1.3 mm. The distance between the pressure member 134 and the plate 112 in FIG. 5 and 6 are 10.1 and 11.4 mm, respectively. 7 and 8 are 16.1 and 17.4 mm, respectively. In the positions of FIG. 5 and 6 engage the gear teeth of the levers 122, 124 the lowest tooth region 114, 116 of the connecting head 110, In the positions of FIG. 7 and 8, the grip is moved up by one tooth step. This corresponds to a change in the distance between the pressure member 134 and the plate 112 by 6 mm. If the lever 142 in FIG. 7 inclined 180 ° according to FIG. 8, the pressure member 134 is reduced by 1.3 mm. The lowering of the pressure member starts from the changed position, whose circumference is 6 mm higher than that in FIG. 5 and 6.

Na opisani način lahko uporabljamo orodje 100 za konektoge štirih razbčnih višin. Če vprijemlje ozobje 114, 116 vzvodov 122, 124 ozobje spojne glave 110 še višje, se lahko ukvaijamo tudi s konektoiji z večjo višino.In the manner described, tool 100 can be used to connect four gap heights. If the clamping gear 114, 116 of the levers 122, 124 of the coupling head gear 110 is even higher, we can also engage with larger heights.

Naj omenimo, daje pritisni člen 134 pritiskan z vzmetema 160, 162 proti ekcentričnemu somikii 136, da dobi pritisni člen 134 lego brez tresljajev.It should be noted that the pressure member 134 is pressed by springs 160, 162 against eccentric somics 136 to obtain the pressure member 134 without vibration.
