This disclosure relates to devices for connecting or splicing wire cables to one another. In particular, this disclosure relates to a cable connector assembly for connecting one or more pairs of wire leads of a first cable to one or more pairs of wire leads of a second cable.
Inline devices for connecting or splicing two cables carrying pairs of twisted wire leads are generally known.
What is needed is an inline copper connector that will use double ended insulation displacement contacts (IDC) with an offset. This connector could be used to connect horizontal cable to cordage with a factory-terminated plug on one end, fulfilling a similar need as would a field-terminable plug connector. This connector can be located away from the attached device, which means space is not constrained, allowing the connector to be larger and easier to terminate.
In accordance with principles of this disclosure, an inline cable connector assembly for connecting one or more pairs of wire leads of a first cable to corresponding one or more pairs of wire leads of a second cable is provided. The connector assembly includes a terminal housing structure including a first base, and a second base facing a direction opposite of the first base. The connector assembly includes wiring cap structure including first and second wiring caps. The first wiring cap is oriented to engage against the first base, and the second wiring cap is oriented to engage against the second base. The connecting assembly also includes one or more pairs of double ended insulation displacement contacts (IDC) within the connector assembly.
In some arrangements, the double ended insulation displacement contacts are operably held within the terminal housing structure.
In some arrangements, the first and second housing parts are latched together.
In some arrangements, the double ended insulation displacement contacts are operably held within the wiring cap structure.
In some embodiments, the first and second wiring caps are latched together.
In some embodiments, the terminal housing structure and the wiring cap structure together form an assembly housing. The assembly housing includes opposite first and second sides, each of the first and second sides having an interlock arrangement to allow for selective removable interlocking of an adjacent assembly housing.
The interlock arrangement may include a projection in one of the first and second sides and a projection-receiving group in the other of the first and second sides.
In one or more embodiments, the first wiring cap is a snap-fit engagement with the first housing part, and the second wiring cap is a snap-fit engagement with the second housing part.
In preferred implementations, the snap-fit engagement between the first and second wiring caps and the first and second housing parts is disengageable with a screw driver.
In some implementations, the first terminal housing part has an open sided aperture for allowing entry of the first cable, and the second terminal housing part has an open sided aperture for allowing entry of the second cable.
In some implementations, the first terminal housing part has a closed aperture for allowing entry of the first cable, and the second terminal housing part has a closed aperture for allowing entry of the second cable.
In some embodiments, the snap fit engagement is accomplished with the use of standard pliers.
In another aspect, an inline cable connector assembly for connecting one or more pairs of wire leads of a first cable to corresponding one or more pairs of wire leads of a second cable includes a housing; and at first and second rows of double-ended insulation displacement contacts held by the housing, each of the contacts having two oppositely directed wire connecting portions electrically connected with an integral jog intermediate the wire connecting portions.
In preferred implementations, the connector assembly is compliant with Category 6A.
In another aspect, a method of connecting first one or more pairs of wire leads of a first cable to second one or more pairs of wire leads of a second cable is provided. The method includes lacing a first one or more pairs of wire leads into a first base; lacing a second one or more pairs of wire leads into a second base, the second base facing a direction opposite of the first base; providing a first wiring cap against the first base; providing a second wiring cap against the second base; and compressing the assembly of the first base, first wiring cap, second base, and second wiring cap so that a plurality of double ended insulation displacement contacts within the assembly penetrate the wire leads and electrically connect the first four pairs to the second four pairs.
A variety of additional inventive aspects will be set forth in the description that follows. The inventive aspects can relate to individual features and to combinations of features. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the broad inventive concepts upon which the embodiments disclosed herein are based.
The accompanying drawings, which are incorporated herein and constitute a part of the description, illustrate several aspects of the present disclosure. A brief description of the drawings is as follows:
The inline cable connector assembly of
The first terminal housing part 18 has a first base 21, which receives a first cable having four twisted pairs of wire leads. The second terminal housing part 19 has a second base 22 that receives a second cable having four pairs of twisted wire leads. In
Both the first terminal housing part 18 and second terminal housing part 19 include an open sided aperture 28, 29 which is shaped to allow a cable to be laid within the respective housing part 18, 19. The cradle shape of the open sided aperture 28, 29 will hold the cable and allows the cable to be laid on the base 21, 22 freely and without having to thread the cable through any closed holes or apertures.
The first and second bases 21, 22 further include a pair of hooked latches 30 opposing each other, such that when the cable is laid on the base 21, 22, the hooked latches 30 will help hold the cable in the base 21, 22.
Other structure in the bases 21, 22 can be seen by studying
The first housing part 18 has an end wall 36 that is the wall opposite of the cable intake having the open sided aperture 28. Similarly, the second terminal housing part 19 has an end wall 37, which is the wall opposite of where the cable enters. Between the spacers 34 and the respective end wall 36, 37, the base 21, 22 includes lead spacers 40, which space and hold the individual leads (wires) in each twisted pair. The lead spacers 40 hold each lead in place and allow it to be electrically connected to the leads in the other cable, when pressed together with the insulation displacement contacts. This is described further below.
As can be appreciated from a review of
The first and second sides 24, 25 of the housing parts 18, 19 include structure to allow it to be connected to the other housing part. For example, in
In accordance with the principles of this disclosure, the connector assembly 15 includes wiring cap structure 46. The wiring cap structure 46 includes a first wiring cap 48 and a second wiring cap 49 that are substantially identical to each other. The first wiring cap 48 is oriented to engage against the first base 21 of the first housing part 18. The second wiring cap 49 is oriented to engage against the second base 22 of the second housing part 19. Each of the first and second wiring caps 48, 49 includes a cable entry port 52, 53. When the first and second wiring caps 48, 49 are operably attached to the first and second terminal housing parts 18, 19, the cable entry port 52 is aligned with the open sided aperture 28, while the cable entry port 53 is aligned with the open side aperture 29. Together, this forms a closed cable entry port that holds each cable as it is entering into the connector assembly 15.
Each of the first and second wiring caps 48, 49 has an exterior portion 56, 57 and an opposite housing part engaging portion 58, 59. The housing part engaging portion 58, 59 faces each respective base 21, 22 and engages against the housing part 18, 19 such when a compressive force is applied, an electrical connection is made between each lead of the four twisted pairs in the cable.
The first wiring cap 48 is in slidable engagement with the first terminal housing part 18. The second wiring cap 49 is in slidable engagement with the second terminal housing part 19. The slidable engagement is accomplished by slide rails 62 projecting from the side wall of the first and second terminal housing parts 18, 19. The slide rails 62 are received within receiving grooves 64 in the wiring caps 48, 49. Ends of the receiving grooves 64 have an inwardly projecting tab 66 that snaps over the end of the rails 62 to help hold the wiring caps 48, 49 together to the housing parts 18, 19. It should be understood that many types of attachment structures are possible, and the position of the rails and grooves could be easily reversed.
Typically, it would not take a specialized tool to provide the slidable and snap fitting engagement between the first wiring cap 48 and first terminal housing part 18, as well as between the second wiring cap 49 and the second terminal housing part 19. Rather, the snap fitting engagement can be accomplished with the use of standard pliers. The snap fitting engagement can be disengaged with a standard screwdriver along the slot 69 (
In accordance with principles of this disclosure, the connector assembly 15 includes a plurality of double ended insulation displacement contacts 70 (IDC) within the connector assembly 15. An enlarged view of one type of usable IDC is shown in
Attention is directed to
In the embodiment of
In accordance with principles of this disclosure, each of the first and second sides 80, 81 has a connection arrangement to allow for selective removable connection to an adjacent assembly housing 78. In the embodiment of
In
A second embodiment of a connector assembly constructed in accordance with principles of this disclosure is shown in
The double ended insulation displacement contacts 70 are operably held within the first and second wiring caps 48, 49. Slots 76 are formed in two rows in the wiring caps 48, 49, rather than in the terminal housing parts 18, 19 of the first embodiment.
The first and second wiring caps 48, 49 are removably latched together using latches 102, 103.
While the connector assembly 15 of the first embodiment has an open sided aperture 28 for receiving the cable, this embodiment has a closed aperture 106 for allowing entry of the cable into the terminal housing parts 18, 19. The closed aperture 106 is received within a groove 108 of the respective wiring cap 48, 49. The cable needs to be threaded within the closed aperture 106.
While structurally, the first terminal housing part 18 and second terminal housing part 19 are identical in the embodiment of
The assemblies 100 have a connection arrangement to allow for selective removable connection to an adjacent assembly. This can be seen in
In this embodiment, the connection arrangement to allow for selective removable connection to adjacent housing assemblies 130 includes projection 110 in one of the first and second sides 80, 81 and projection-receiving groove 112 in the other of the first and second sides 80, 81. In this embodiment, the receiving groove 112 is formed by ribs 116, 117 that curled toward each other to contain the groove 112 therewithin. The projection 110 is formed by a T-shaped flange 132 that is sized to be received within the groove 112.
Otherwise, the assembly 130 is structured similarly to the assembly 110.
Another embodiment of a connector assembly constructed in accordance with principles of this disclosure is shown in
In this embodiment, there is a provision for an internal cable tie for strain relief. In particular, attention is directed to
Another feature of connector assembly 200 includes a modification to the slots 69 that allow disassembly with a screwdriver. The slot 69 further includes indents at 210, 211 to permit the wiring caps 48, 49 to be removed using a thumbnail or fingernail.
Again in reference to the assembly 200, another difference from the embodiment of
The connection arrangement (e.g., each connector assembly 15, 100, 200) as described herein is capable of compliance with Category 6A, which is a set of minimum requirements specified in the “568-C.2 TIA Standard” for twisted pair telecommunication cabling components used in building and campus telecommunication networks. In such networks, the information signal is normally transmitted over a pair of conductors, known as the “tip” conductor and the “ring” conductor, as a voltage difference between the two conductors. This type of signal is known as a differential mode signal. Under certain conditions another type of signal may exist on the pair whereby the same voltage is applied to the two conductors. This type of signal is known as a common mode signal.
The reason why differential mode signaling is the method of choice for carrying the information signal on a twisted pair is that such a signal is not affected by far field electrical noise from external sources since such noise elevates the voltages of both conductors equally. When the information signal on a twisted pair passes through a pair of contacts in a multi-pair connector, however, asymmetry between these contacts and the contacts of an adjacent pair, depending on the contact array geometry, causes a portion of this signal to couple unequally to the adjacent pair causing both differential and common mode disturbances known as differential mode and common mode crosstalk. The combination of disposing the contacts, as described above, into two rows, as shown in
Several features (e.g., the spacers, etc.) of the various embodiments ensure that the twisting of the cable pairs is maintained to within a very short distance, e.g. under 4 mm. This feature leads to advantage because any un-twisting of adjacent pairs causes differential and common code crosstalk between them that is difficult to compensate for because of the unpredictability of its magnitude and the excessive time delay between where it occurs and where it can be compensated for in the connector.
A method of connecting inline one or more pairs of wire leads of a first cable to one or more pairs of wire leads of a second cable can be followed using the principles described herein. For example, as shown in
The method includes lacing one or more pairs of wire leads into first terminal housing part 18. For example, In
The method includes providing first wiring cap 48 against the first base 21 of the first terminal housing part 18. The method includes providing second wiring cap 49 against the second base 22 of the second terminal housing part 19.
The method includes compressing the assembly of the first terminal housing part 18, the first wiring cap 48, the second terminal housing part 19 and the second wiring cap 49 so that it plurality of double ended insulation displacement contact 70 within the assembly 15 penetrate the insulation of the wire leads and electrically connect the one or more pairs of the first cable to the one or more pairs of the second cable.
The step of compressing can be accomplished without the use of specialized tool. For example, the step of compressing can include using standard pliers, such as ChannelLock® tongue and groove pliers to compress against the first wiring cap 48 and second wiring cap 49 and squeeze the assembly together to allow the insulation displacement contact 70 to displace the insulation and make electrical contact with the leads.
The method may also include laterally attaching adjacent assemblies 15 to each other. For example, one assembly 15 may be placed laterally next to another assembly and then a tether or zip tie 84 can be used to hold the two assemblies together. The zip tie 84 can be placed in an open channel formed between the housing parts 18, 19 and the respective wiring caps 48, 49.
The above represents inventive principles. Many embodiments can be made utilizing these principles.
