Abstract

A modular plug connector is constructed with an array of substantially planar conductor positioning channels that position individual conductors for termination by a plurality of flat insulation displacement contacts. A plurality of conductor termination slots are formed parallel to and communicating with every other one of the conductor positioning channels such that insertion of insulation displacement contacts during termination of the contacts to the conductors forces every other conductor into a respective slot offsetting or staggering adjacent conductors. The modular plug is provided with a latch arm that includes a free end that prevents snagging or tangling of the latch arm with other connectors or surfaces.

Description

Modular plug connector

The present invention relates generally to be used for the modular plug connector that electrical termination is specifically related to match with modular plug connector and jack with being electrically connected the standard communication connector of communication cable lead.

Many must being widely used or being suggested with the essentially identical different modular plug of profile that the box-like socket of a kind of standard group cooperates.For example the United States Patent (USP) of Hardesty discloses for No. 4054350 to some extent.

The size of modular plug is considerably little, thereby the plug of lead and terminal lean on very closely, this just cause in the plug connector of prior art different signals between cross-talk.

The application that is connected the modular communications plug and socket with the twisted pair cable in the computer network that the message data rate of improving constantly requires causes a kind of so continuous demand, promptly to reduce by the modular communications connector cause the signal transfer line between cross-talk.

The quite little size of described plug and lead also requires single insulated conductor operated carefully accurately to arrange lead and injects lead in the plug and give clamping till described plug can be terminated on the lead with respect to the order of the contact on the modular plug and by suitable arrangement.Usually, eight single insulated conductors must be arranged and terminate on eight contacts in the plug.

A kind of plug of being made by Stewart wire installation Co., Ltd utilizes a kind of wires carry bar that separates, described carrier bar allows to remain on the edge of described carrier bar in internal stranded of each lead always, when comparing with previous plug connector, this has just reduced the quantity of caused cross-talk in adjacent wires.Described carrier bar makes the manufacturing of plug complicated and compare with the plug of prior art and to have increased the difficulty of this plug assembling, and in prior art, can only be straightend by the end of stranded lead and be inserted in the plug and do not need to handle carefully each root lead and enter in the described load beam with a kind of planar array.

Like this, just need improve so that a modular plug contact to be provided prior art, this modular connector can be easily termination in addition, reduce simultaneously by by the caused cross-talk of connector of the lead centering of termination.

Modular plug normally is arranged in the multipart shell and terminates on the cable to be formed for the core of a cable in the confined space, the core of a cable in terminal block or the truck for example it is desirable to plug like this and just can not tangle or twist and stumble with other plug, core of a cable or some other surface.The plug of prior art comprises a latch arm that stretches out from each plug body.

People's such as Sa Tuo United States Patent (USP) has proposed the thin switch member that slit a kind of and at an end of latch arm matches, constitutes for No. 5100339 on plug.This scheme that is suggested obviously is difficult to make owing to described thin switch member is damaged easily.Can also note Figure 11 of this patent of Sa holder, it has disclosed a kind of connector of prior art, this connector utilization be arranged on the closely close either side of described latch arm on the barrier that protrudes upward tangle to stop latch arm and other surface.These barriers hinder the release of latch so that plug is removed from a socket.

Like this, in present technique, just need a kind of improved plug connector, described plug connector can stop the latch arm of plug and other object to tangle and do not hinder latch manipulation so that plug discharge from a socket.An object of the present invention is to provide a kind of connector, this connector reduce the lead of terminating on the described connector between cross-talk and the lead of a planar array can be inserted connector and termination in addition simply.

Another object of the present invention provide a kind of with can reduce described connector termination lead between such mode of cross-talk a connector is terminated to method on the multiple conducting wires.

Another purpose of the present invention provides a kind of like this connector, and this connector can prevent that its latch arm and other connector or surface tangle.

In general, a connector that is used for the right multiple conducting wires of a plurality of leads of termination comprises that one is used for that described lead is positioned at first device in the array on a basic plane at first and is used to make one of lead at least to be positioned at another root part of leaving lead so that lead between second device that reduces of cross-talk.Described first device that is used for positioning lead comprises a plurality of basic planar conductor line placed channels, described second device that is used to locate comprises: the conductor termination otch of the adjacent setting of one of at least one and lead, one be installed in the described connector and with lead placed channel translation plug and adjacent conductor termination otch in line so that make the termination power that is applied on the described plug plug be shifted on the lead in the lead placed channel that initially is positioned in aligning and described lead moved in the conductor termination otch of described aligning.

A kind of a connector is terminated to method on the multiple conducting wires, described connector comprises a plurality of connector placed channels substantially in one plane, described passage has a path with the adjacent setting of at least one conductor termination otch at least, and described method comprises the following steps: arrangements of conductors in a basic planar array; Wire array is embedded the lead positioned channel of described connector; And with at least one lead move into one in described array away from the connector termination otch of an adjacent wires to reduce the cross-talk between lead.

The connector that nothing is tangled has one from its outwardly directed latch arm, it is included in a free end that inwardly stretches out that forms on the described latch arm, described free end inwardly stretches out facing to a point with described surperficial close enough towards a surface of connector, so that described latch arm seldom may tangle or stumble with other object.A depression can be formed for supporting a described free-ended end so that described end extends under described connector surface in the connector surface that is disposed.

Adopting a knockdown communication plug connector of notion of the present invention generally is to represent with label 20 in these accompanying drawings.Modular plug is to make with Merlon integral body.

More satisfactory be modular plug connector 20 to design can termination one twisted pair cable 22 insulated conductor 21.The signal of lead 21 is stranded in together to reduce the cross-talk between lead and to be encapsulated in the protection sheath 23 of cable 22 length along them.Connector 20 can also be used to cable, flat cable or any cable of the non-twisted pair of termination, and the lead of these cables is formed maybe can be configured a planar array.

Plug 20 comprises a front surface, upper wall 25, first and second sidewalls 26 and 27 and one lower wall 28.They form a cable holding channel 29 together.Passage 29 with in upper wall 25, form and run through one of front surface 24 basically eight electric wire positioned channels 30 of planar array be connected, each lead positioned channel 30 is to form on upper surface and lower surface by upper and lower ridge 31 and 32 (Fig. 5), and a described ridge distance at interval also accurately is positioned between the upper and lower ridge with ccontaining each lead 21.Thereby path 30 is more satisfactory be by connector 20 can insert the terminal of lead 21 and by front surface 24 with catch lead 21 and with its outwards pulling draw in the width that make the parallel end portion of adjacent wires 21 in the connector 20 as much as possible with the twisting portion that each lead is right and be reduced to minimum degree, reduce thus lead between cross-talk to improve the performance of connector.

Cable passage 29 comprises solid conductor 21 is incorporated into locational inside tapered wall 33 (Fig. 6) at separately lead positioned channel 30.

As being clearly shown that among Fig. 6-12, with and adjacent setting parallel every a lead positioned channel 30 be four conductor termination slits 34, these otch are parallel to path 30 and run through the front surface 24 of connector.Slit 34 converges and is communicated with alternate path 30 separately so that a lead 21 in the lead positioned channel 30 that is initially positioned at separately can laterally be moved in the slit 34 of a vicinity by incision length along their length.

Last ridge 31, (as shown in Figure 10), inwardly outstanding enough distances are positioned at leads 21 in the path 30 with conflict and make that this lead is unlikely freely to be entered in the slit 34, on the other hand, for electric wire 21 is pushed in the slit 34 when the termination, otch 34 has enough spacing distances.

A plurality of contact otch 35 form on the diapire of connector 20, each contact otch 35 is aimed at one of lead positioned channel 30 and is communicated with, be aligned so that be positioned at the interior planar isolated displacement contact of contact otch, thereby termination is positioned in the lead 30 in the lead positioned channel.

As being clearly shown that among Fig. 9 and Figure 10, planar isolated displacement contact 36 and translation are isolated displacement contact 37 and are arranged in the contact otch 35.Displacement contact 36 of isolating and each of 37 comprise hangnail 38, a body portion 39 and the outer contacting bizet of charging into 40.

As shown in Figure 10, the body of translation contact 37 on length greater than the body of contact 36.Translation contact 37 is arranged in the contact otch of aiming at conductor termination otch 34 35.

As shown in Fig. 6 and Fig. 9-12, upper conductor location ridge part initial with hangnail the aim at part that with clamping be positioned at the electric wire 21 of ridge part relative with the hangnail 38 of contact 37, so that make before the lead translation advances conductor termination otch 34, the hangnail 38 of contact 37 is exposed the insulation of lead 21, thereby guarantees the bond-off of lead 21 unlikely and contact 37 in the process of termination.

As being clearly shown that among Fig. 5-8, lower wire location ridge 32 extends to the whole length of lead positioned channel 30, and upper conductor location ridge 31 just from the entrance extension of path 30 to just by contact otch 35 a bit on.Like this, when by the lead of contact 37 terminations in contact otch 35, the free end portion that stretches out the lead 21 outside the contact 37 can freely unhinderedly move in the contact termination otch 34 and can not influence the quality of the conduction engagement between contact and lead, if and ridge 31 extends to the whole length of path and otch 34 thereby the free end of lead 21 can not freely move in the contact termination otch 34, the situation that influences quality just may produce.

Contact 36 and 37 enters the termination that combines with lead 21 conduction and realizes by eight

contacts

36 and 37 inwardly being pushed with 21 engagements of each solid conductor, and the end that the translation contact of aiming at conductor termination otch 34 37 than growing makes each root lead moves to a contact otch 35 with lead 21 terminations from lead placed channel 29.Please see Figure 11 and 12.The contact 36 of shorter length is termination lead 21 in lead positioned channel 30 separately.

Contact

36 and 37 relative length will be selected by

contact

36 and 37 and after lead 21 is terminated, and the contact bizet 40 that makes

contact

36 and 37 in line.Please see Figure 12.

It is to form on diapire 28 and be configured to and can be meshed with the sheath 23 of cable 22 that a kind of traditional stress is eliminated wedge 41 (Figure 13).

The conductor termination of the twisted pair cable in connector 20 is realized by the following step: an end of removing the sheath of cable 22, by untiing and arrange eight leads 21 under a parallel direction and the correct order in a basic planar array, the distance of parallel end will can be caught the array that is arranged securely in the process of inserting connector 20, the free end of lead stretches out front surface 24 by the array of lead positioned channel 30 insertion leads 21, the free end that spurs lead outwardly draws in the connector securely with the twisting part that each lead is right as much as possible can 37 near contact 36 with the stranded part that guarantees lead, force

contact

36 and 37 to enter with the conduction of lead 21 with a modular plug end joining tool (not shown) and combine and force stress elimination wedge 41 to enter lead 21 parts of stretching out the front surface 24 of connector 20 with the engaging of sheath 23 (Fig. 9-13) and cut-out.End joining tool (not shown) initial with isolate on the lead 21 of displacement contact 37 engagements with the lead positioned channel 30 that forces contact 37 inwardly to be pressed against to be positioned at separately.The continuation of contact 37 inwardly motion forces the lead 21 between last ridge 31 to enter in the conductor termination otch 34, and instrument and contact 36 and 37 mesh with all contacts of

inside promotion contact

36 and 37 is terminated on the lead 21 subsequently.A kind of alternative terminating method can cut off the conductor part of the front surface 24 that stretches out connector 20 after lead being strained in the connector 20 and before terminating to contact 36 and 37 on the lead 21.

In order to prevent the lead 21 unnecessary possibilities that contact after any and the termination, can after lead 21 terminations, come closed and sealed path 30 and otch 34 with a snak link stifle (not shown) or other device.

As shown in Fig. 1,3 and 13, connector 20 comprises a guide end (guiding projection branch) 45 that form and that stretch out antetheca 24 on upper wall 25, and described guide end is designed to be connector to be inducted into the socket connector of a standard and accurately aims at.As shown in Figure 3, guide end 45 medially aim at connector 20 width and only with four conductor termination otch 34 in three adjacent.Guide end 45 comprises an anvil face 46 (Figure 13), and described anvil face is supporting three leads 21 in the conductor termination otch 34 that are arranged near guide end 45 in the process of cutting off lead 21.As shown in Figure 3, the lead 21 in the termination otch 47 that does not have supporting is not supported by anvil face 46, and this may hinder the cut-out fully of the lead 21 in otch 47 structure of dependence end joining tool.In order to prevent any this possibility, can revise connector 20 with the termination otch 47 that removes the supporting of this nothing and only utilize one with the adjacent lead positioned channel 48 lead positioned channel 30 that adds in line, so only used three conductor termination otch 34 that stagger and still can reach the performance of class 5.Or another kind of scheme is to form on the position that the otch 47 of Fig. 3 can stagger in a part between otch 34 that is staggered fully and the path 30.

When being used for termination and satisfying the cable of the shielding of EIA/TIATSB-36 standard or unscreened 100 ohm of cable twisted pair the 5th grades, the layout that finally staggers of lead 21 ends provides a kind of like this plug connector, and this plug connector has been found and can have made the cross-talk amount that is caused by described connector be enough to reduce

To surpassing Electronic Industries Association and telecommunication TIA regulation all the time, promptly in the cross-talk properties of the 5th grade of technical conditions SP-2840 " EIA/TIA " prescribed by standard, plug and cable are to carry out overtesting and plug by the TSB-67 qualification test equipment that is used for the 5th grade approval to carry out overtesting separately under the condition that the termination part of TSB-40 requires, but provide a kind of can make economically and easily termination connector and do not need to use a kind of conductor loading bar that separates, as long as by the lead of a planar array is inserted connector and termination plug connector.

Though above-mentioned explanation is to be used for a modular plug connector, but the present invention can be used to reduce any type of connector of the inner cross-talk of connector, and more satisfactory here is the lead of a basic planar array will be positioned at the described connector that is used for termination at first.

As being clearly shown that in Fig. 1 and 7, connector 20 comprises the latch arm 50 of a cantilever, and described latch arm has and outwards leaves that connector extends and a first that integrally constitutes with connector 20 and a free end 52 that is connected with described first by a hinges 53.Free end 52 extends (and terminate in be in close proximity to upper wall 25 parts) downwards towards the upper wall 25 of connector 20, so that free end 52 seldom may tangle (seeing Figure 14) with the latch arm of other connector 20 in the housing of a connector 54, perhaps in use snap-on on other surface.Latch arm 50 can prevent that it tangles or stumbles, and does not spin off from a socket to help connector 20 near the latch arm and can freely there be the ground of obstruction in use.

Another embodiment is shown in Figure 15-17, shows a connector 55 among the figure, and this connector has a latch arm 56 that does not tangle, and described latch arm has above-mentioned and described in Figure 15-17 and those common features of enumerating.Connector 55 comprises the Embedded Division or the depressed part 57 that form in the upper wall 25 of connector 55, described depressed part 57 be set to the end 58 that can hold free end 52 in case terminal 58 extend under the surface of upper wall and can be not endways 58 and upper wall 25 between leave any spacing with prevent may be betwixt the stumbling of other object.

Though illustrated and described concrete preferred embodiments more of the present invention, obviously, can make all variations and modification person skilled in the art under the situation of disclosed content.
