BACKGROUND
Electrical connectors are useful for providing a connection point for telecommunications systems. For example, RJ-type connectors can be provided as wall sockets wherein electronic data cables are terminated and mating electrical plugs can be inserted into the sockets. Frequently, this termination process occurs in the field and at the actual location where the cables to be attached to the connectors are being installed. In such instances, it is often necessary to provide a grounding connection between the cable and its attached connector.
SUMMARY
A connector assembly is disclosed. Connector assemblies including a grounding component are disclosed. The disclosed connector assemblies provide for a compact cable clamp/shield connection method that can accommodate a large range of cable sizes. For example, the disclosed clamp can accommodate cables ranging from 4.6 to 9.0 mm. Another feature of the disclosed assemblies is that all parts of the grounding features are inboard of the sides of the connector assembly or jack such that no protrusions exist. As the connector assemblies or jacks are to be used in high density applications, where in some cases they are mounted side by side and or back to back, any protrusions from a clamp outside the connector assembly bodies would prevent this configuration.
In one example, a connector assembly is disclosed including a connector part defining a front housing having a jack cavity and a cable manager part having a rear housing and a grounding part. The rear housing defines a central aperture through which a cable having an exposed conductive element can extend. The grounding part secures the rear housing to the front housing and provides grounding contact between the cable conductive element and the connector part. In one example, the cable manager part includes a lacing fixture part securing individual wires of the cable terminated to the connector part that is secured between the grounding part and the front housing.
A method for assembling a connector assembly is also disclosed that includes the steps of: providing a connector part defining a front housing having a jack cavity; providing a cable manager part including a rear housing and a grounding part, the grounding part being for providing a grounding connection between a sheath of an inserted cable and the connector part; securing the grounding part to the rear housing; and securing the grounding part to the front housing such that the front housing is secured to the rear housing.
In one example, a connector assembly is disclosed including a connector part defining a front housing having a jack cavity and a cable manager part having a rear housing and a grounding arrangement. The rear housing defines a central aperture through which a cable having an exposed conductive element can extend. The grounding arrangement is secured to the end wall of the rear housing and includes a plurality of deflectable flange members extending across the central aperture. The flange members are arranged to provide a spring force against the cable and grounding contact between the cable conductive element and the connector part.
A method for assembling a connector assembly is also disclosed that includes the steps of: providing a connector part defining a front housing having a jack cavity; providing a cable manager part including a rear housing and a grounding arrangement including a plurality of separate grounding members, the grounding arrangement being for providing a grounding connection between a sheath of an inserted cable and the connector part; securing each of the grounding members to an end wall the rear housing; and securing the front housing to the rear housing.

DETAILED DESCRIPTION
Various embodiments will be described in detail with reference to the drawings, wherein like reference numerals represent like parts and assemblies throughout the several views. Reference to various embodiments does not limit the scope of the claims attached hereto. Additionally, any examples set forth in this specification are not intended to be limiting and merely set forth some of the many possible embodiments for the appended claims.
A telecommunications connector 10 for grounded connection with a cable 4 having a conductive element 5 and a plurality of wires 6 is shown. One example of a suitable cable 4 is shown at FIG. 29. As used herein, term “conductive element” is defined as including any type of conductive element, shield, or sheath disposed over the cable jacket, including metal braids, meshes, foils, drain wires, and combinations thereof. In one example, the cable 4 includes a plurality of insulated copper wires 6, for example, four sets of twisted wire pairs, while the connectors 10 are modular or RJ-type connectors.
As shown, the telecommunications connector 10 has a connector part 12 that mates to a cable manager part 20, each of which includes further subassemblies. As shown, the connector part 12 includes a jack cavity 14 for receiving a corresponding plug (not shown). A cover assembly 100 having a rotatable dust cover 90 is shown as providing selective access to the jack cavity 14, as discussed in more detail later. The connector part 12 can include a plurality of electrical contact members or conductors 16 for which electrical connection to the wires 6 will be made through a termination and connection process. As shown, the connector part 12 is configured with a front housing 18 having conductive sidewalls 18a (18a1, 18a2) which are formed from a conductive material, such as a metal material. In one aspect, one or more of the sidewalls 18a can define a respective recess portion 18b. As shown, two recess portions 18b (18b1, 18b2) are provided. The recess portions 18b receive and connect to portions of the connector part 20, such that conductive contact is established between the cable manager part 20 and the sidewalls 18a of the connector part front housing 18. Accordingly, the connector 10 is grounded to the cable conductive element 5 via the cable manager part 20 and the sidewalls 18a of the connector part 12.
In one aspect, the connector part front housing 18 is provided cutting edges 18c which are designed to cut the wires 6 of the cable 4 during the termination process. One example of a suitable termination process and connector part is shown and described in Spain patent application P201530417, entitled Connector Assembly with Grounding Spring and filed on 27 Mar. 2015, the entirety of which is incorporated by reference herein. Another example of a suitable termination process and connector part is shown and described in Spain patent application P201531199, entitled Connector Assembly with Grounding Spring Clamp and filed on 13 Aug. 2015, the entirety of which is incorporated by reference herein.
In one aspect, the cable manager part 20 can be further provided with a lacing fixture 30, a rear housing 40, and a grounding part 50. As configured, the grounding part 50 latches and secures the connector part front housing 18 to the rear housing part 40 such that the lacing fixture is clamped therebetween.
The grounding part 50 is shown in isolation at FIGS. 24-27. As presented, the grounding part 50 is provided with and end wall 50a which defines an aperture 50b. A plurality of flange members 50c extends from the end wall 50a towards the center of the aperture. As shown, each of the flange members 50c includes a main portion 50d extending from a base end 50e proximate the end wall 50a to a tip portion 50f. Each of the flange member main portions 50d extend at a first angle a1 away from the end wall 50a at the base portion 50e while the tip portion 50f extends at a second angle a2 relative to the base portion 50e. As shown, the first angle a1 is about 44 degrees while the second angle a2 is about 60 degrees. Other angles are possible. The main portions 50d are disposed at the first angle a1 to facilitate insertion of the cable 4 while providing the optimal spring force against the cable sheath 5. The tip portions 50f are bent to the second angle a2 so that the flange members 50c do not present a sharp edge against the cable sheath 5 as it is passing by the flange members 50c, which also facilitates removal of the cable after insertion. In one embodiment, the grounding part 50 is formed from a metal material, such as stainless steel or a copper alloy.
The grounding part 50 can also be provided with sidewalls 52a, 52b, 52c, 52d, and with arm extensions 52e, 52f, each of which extends from the end wall 50a. As shown, the sidewalls 52a, 52b, 52c, 52d extend generally orthogonally from the end wall 50a while the arm extensions 52e, 52f extend at a slight oblique angle a3 to facilitate insertion of the grounding part 50 into the rear housing 40. The sidewalls 52a, 52b are respectively provided with bent portions or tabs 54a, 54b and 54c, 54d that serve as latches that engage with corresponding recess portions 44a, 44b and 44c, 44d of the rear housing 40. The extension arms 52e, 52f are provided with bent portions or tabs 54e, 54f that also engage with recess portions 44e, 44f of the rear housing 40. The extension arms 52e, 52f are further provided with bent portions or tabs 54g, 54h and with orthogonal flange portions 54i, 54j. The tabs 54g, 54h engage with recess portions 18d, 18e of the front housing 18. The flange portions 54i, 54j extend orthogonally into corresponding slots or recesses 44h, 44g in the rear housing part 40 and into slots or recesses 18f, 18g in the front housing 18 so that when an attempt is made to separate the front housing 18 from the rear housing 40, there is a shear effect acting on the flange 54i, 54j. Thus, the flanges 54i, 54j provides increased retention force, since any removal force would be applied against the flanges 54i, 54j in a shear force condition. The angled tabs or latches 54g, 54h act as a means of deflection so that the locking flanges 54i, 54j are deflected to allow for the wall of the rear housing part 40 to run past before locking into the slots 18d, 18e.
The rear housing 40 is shown in isolation at FIGS. 13-17. The rear housing includes an end wall 40a defining a central aperture 40b. The rear housing also includes sidewalls 42a, 42b, 42c, and 42d which extend from the end wall 40a. Together, the sidewalls 42a-42d and the end wall 40a form an interior cavity into which the grounding part 50 is received. The grounding part 50 is received by the rear housing 40 such that the end walls 40a and 50a are adjacent and such that the central apertures 40b and 50b are coaxially aligned. As stated previously, the grounding part 50 is secured to the housing part 40 via tabs 54a, 54b, 54e which respectively latch into recesses 44a, 44b, 44e in the sidewall 42a of the housing part 40 and via tabs 54c, 54d, 54f which respectively latch into recesses 44c, 44d, 44f in the sidewall 42b of the housing part 40.
The rear housing 40 is also shown as including projecting sidewalls 42e, 42f which respectively extend from sidewalls 42a, 42b. In one aspect, the connector part 12 and the cable manager part sidewalls 42e, 42f may be configured in a complementary manner, so that the connector part 12 is able to engage with the cable manager part 20 only in one orientation. For example, the recess portion 18b1 on one side of the front housing 18 may be configured with a different size and/or shape than the recess portion 18b2 on the opposite side of the front housing 18. As can be seen at FIGS. 2 and 3, the rear housing 40 is provided with a pair of projecting sidewalls 42e, 42f that are respectively received into the recess portions 18b1, 18b2. Each of the projecting sidewalls 42e, 42f is provided with a different shape corresponding to the recess portion 18b1, 18b2 into which it is intended to be received within. Accordingly, the rear housing 40 can only be fully engaged and connected to the front housing 18 in only a single orientation.
Once the grounding part 50 is received and secured to the rear housing 40, the lacing fixture part 30 can be received by the rear housing 40. As shown, the lacing fixture part 30 includes a lacing fixture or structure 32, a pair of sidewalls 34a, 34b, and a perimeter wall structure 36. The lacing fixture 32 and perimeter wall structure 36 define a central aperture 30a that, once the lacing fixture part 30 is installed, is coaxially aligned with central apertures 40b and 50b. The sidewalls 34a, 34b and the perimeter wall structure 36 each extend from the lacing structure 32. The lacing structure 32 functions to place the wires 6 in the appropriate orientation for termination. An example lacing structure 32 suitable for use with the lacing fixture part 50 disclosed herein can be found in Spain patent application P201530372 entitled Connector with Separable Lacing Fixture and filed on 20 Mar. 2015, the entirety of which is incorporated by reference herein. As can be most easily seen at FIG. 4, the perimeter wall structure 36 receives the flange members 50c. The perimeter wall structure 36 supports the flange members 50c within recessed portions 36a when the flange members 50c are deflected sufficiently by an inserted cable 4. The ends of the sidewalls 34a, 34b and the perimeter wall structure 35 engage against the grounding part end wall 50a such that, when a cable 4 is inserted, the flange members 50c deflect relative to the end wall 50a. FIG. 5 shows a cable 4 inserted into the cable manager part 20 such that the flange members 50c are deflected towards and partially into the recessed portions 36a with the ends of the sidewalls 34a, 34b and perimeter wall structure 36 engaging against the grounding part end wall 50a.
The assembled cable manager part 20 with the lacing fixture part 30 and grounding part 50 mounted to the rear housing 40 can be seen at FIG. 6. At this stage, the cable manager part 20 can be secured to the connector part 12. As noted above, this is accomplished by aligning the cable manager part sidewalls 42e, 42f with the corresponding recess 18b1, 18b2 on the front housing 18. As the two components 12, 20 are brought together, the tabs 54g, 54h respectively latch into recesses 18d, 18e in the sidewalls 18a1, 18a2. Because the grounding part 50 is latched to the rear housing 40, this final latching secures the rear housing 40 to the front housing 18 with the lacing fixture part 30 sandwiched between. To further aid in retaining the rear housing 40 to the front housing 18, the front housing 18 can be provided with recesses 18i, 18j which receive corresponding protrusions 44i, 44j on the rear housing part 40 such that a snap-fit type connection is achieved. This feature provides increased retention force between the two housings 18, 40. Once the cable manager part 20 is fully assembled onto the front housing 18 and the termination process is complete, portions 32a, 32b, and 32c of the lacing fixture 30 are removed such that the lacing fixture 30 does not extend beyond the outer profile defined by the front housing 18. FIGS. 1-5 show the lacing fixture 30 with the portions 32a, 32b, 32c removed.
With reference to FIGS. 2 and 3, it can be seen that a gap 60 is formed between the housings 18, 40, after assembly, such that a portion of the extension arms 52e 52f, is exposed. This gap 60 serves as access to deflect the latch using the flat blade of a screwdriver to deflect the extension arms 52e, 52f by inserting and twisting the blade. This action causes the tabs 54g, 54h to be disengaged from recesses 44g, 44h, thereby allowing for removal of the rear assembly for re-termination. Material of the lacing fixture 30 rests behind the lower part of the extension arms 52e, 52f and prevents the latches 54e, 54f from becoming separated from the rear housing during this action.
In one aspect, the disclosed cable manager part 20 can accommodate a variety of differently sized cables 4. For example, cables 4 ranging between 4.6 millimeters to 9 millimeters in diameter can be accepted and grounded by the same cable manager part. Additionally, no active steps are required on the part of the installer to ground the cable to the connector assembly 10 once the cable 4 is properly stripped and inserted into the cable manager part. This is in contrast to other designs where a clamp must be actively opened or closed by the installer during insertion.
With reference to the exploded view in FIG. 28, the front housing part 18 of the connector assembly 10, a latch member 70 connectable to the front housing part 18, and a cover assembly 100 also connectable to the front housing part 18 are shown. FIGS. 29-32 additionally show the isolated front housing part 18. The front housing part 18 is provided with several features that enable the latch member 70 and cover assembly 100 to be connected to the front housing part 18. For example, the front housing part 18 is provided with a pair of recessed regions 18k defined by sidewalls 18m that is recessed from the main sidewalls 18a1, 18a2 and a latching protrusion 18n extending from each sidewall 18m. The front housing part 18 includes a perimeter wall 18p and a plurality of raised structures 18q, 18r, 18s that cooperatively receive the cover assembly 100 in sliding or press-fit manner. The front housing part 18 additionally includes a latch recess 18t for retaining the cover assembly 100 onto the front housing part 18.
Referring to FIGS. 33 to 38, the latch member 70 is shown in isolation. In one aspect, the latch member 70 can be removably attached to the front housing part 18. The latch member 70 is for securing the connector assembly 10 within an opening of a connector panel. In one example, the latch member 70 is a unitary structure formed from a metal material, such as steel. A plastic material may also be used, although metal is preferred due to more suitable strength and flexibility properties, and because metal allows the latch member 70 to be made from a relatively thin material. Where metal is used, the latch member 70 can also serve to provide a grounding pathway.
As most easily seen at FIGS. 33-38, the latch member 70 can be provided with a first portion 72 and a second portion 74 that are joined by a third portion 76. As presented, the third portion 76 is curved or represents a bent portion of the latch member 70 such that the third portion 76 enables the latch member to perform a spring function. As shown, the third portion 76 holds the first portion 72 at an non-zero angle with respect to the second portion 74.
In one aspect, the first portion 72 extends to a free end 72a and includes a pair of locking rib structures 78, wherein each of the locking ribs includes a first rib 78a and a spaced apart second rib 78b. The locking rib structures 78 are for engaging with the connector panel. Once installed, the first ribs 78a engage a front side of the connector panel while the second ribs 78b engage a back side of the connector panel such that the connector assembly 10 is locked in place into the opening of the connector panel. An example connector panel and a latch member with overlapping features with latch member 70 is shown and described in PCT Publication WO 2016/156644, the entirety of which is incorporated by reference herein.
In another aspect, the second portion 74 includes a retention structure 80. The retention structure 80 is for providing a secure connection between the latch member 70 and the front housing part 18 of the connector assembly 10. As shown, the retention structure 80 includes a pair of tabs 82 extending generally orthogonally from the latch member second portion 74. In one aspect, the tabs 82 are shaped to fit within the recess regions 18k defined in the front housing part 18 (i.e. the profiles of the tabs 82 and recessed regions 18k match or the profile of the tabs 82 is smaller than that of the recessed regions 18k). The recess regions 18k are generally of a depth that matches a thickness of the tabs 82. Accordingly, once the latch member 80 is installed onto the front housing part 18, a flush configuration results in which the tabs 82 do not extend past the sidewall surfaces 18a1, 18a2 of the housing part 18. In one aspect, the tabs 82 define an open region 84 for receiving the latching protrusion 18t on the front housing part 18. This arrangement facilitates a snap-fit type of connection between the latch member 70 and the front housing part 18. As with other similar types of connections described herein, the latch member 70 could be provided with protrusions similar to protrusions 18t while the front housing part 18 could be provided with recesses similar to open regions 84.
Referring to FIGS. 39-44, the cover assembly 100 is shown in isolation. As shown, the cover assembly 100 includes an outer perimeter wall 102 that extends to an end wall 104 having an aperture 104a that provide access to the jack cavity 14. The outer perimeter wall 102 is configured to slide over the perimeter wall 18p of the front housing part 18 and between the raised structures 18q, 18r, 18s. The outer perimeter wall 102 is provided at a thickness that is the same as the raised structures 18q, 18r, 18s, thereby enabling the cover assembly 100 outer profile to match that of the front housing part 18. A latch extension 106 is also provided that includes a latch member 106a that engages with the latch recess 18t of the front housing part 18. This configuration allows for the cover assembly 100 to form a secure, snap-fit type of connection with the front housing part 18.
In one aspect, the cover assembly 100 includes a pair of female hinge members 108 extending from the end wall 104. The female hinge members 108 receive a male hinge member 96 on a cover portion 90 of the cover assembly 100 such that the cover portion 90 can rotate between open and closed positions. In the open position, the cover portion 90 provides access to the jack cavity 14. In the closed position, the cover portion 90 acts as a dust cover for the jack cavity 14. As shown, the cover portion 90 includes a handle 92 for aiding an operator to digitally manipulate the position of the cover portion 90. The cover portion 90 is also shown as having a pair of protrusions 94 on the opposite side from the handle 92. The protrusions 94 engage interior portions of the jack cavity 14 in a frictional manner to aid in retaining the cover portion 90 in the closed position.
Referring to FIGS. 45-50, a cap 100′ is shown that is largely identical to the cover assembly 100. Accordingly, similar features need not be repeated here. The cap 100′ is different from the cover assembly 100 in that a cover portion 90 is not provided, thereby leaving the jack receptacle 14 exposed through the opening 104′ of the cap 100′. Thus, the cap 100′ is also not provided with the female hinge members that are present on the cover assembly 100. Where it is desired to add a cover portion to the cap 100′, a recess 108′ is provided to receive and secure an extension portion of a removable cover portion.
An alternative configuration for a connector assembly 110 including a connector part 112, a cable manager part 120, and grounding arrangement 150 is illustrated at FIGS. 53 to 63. The connector part 112 is generally similar to connector part 12 and like reference numbers (e.g. 112 instead of 12) are therefore used for the same features. In one aspect, the cable manager part 120 is provided with a rear housing 140 to which the grounding arrangement 150 is attached. The grounding arrangement 150 makes grounding contact with the cable sheath 5 such that grounding contact is established between the rear housing 140 and the sheath 5. The cable manager part 120 is in grounding contact with the connector part 112. Accordingly, the grounding arrangement 150 operates to facilitate grounding contact between the sheath 5 and the connector part 112 as can be seen at FIG. 60.
The grounding arrangement 150 is shown in isolation at FIGS. 61 to 63. In the example shown, the grounding arrangement 150 is formed by a plurality of grounding members 152 arranged to form a central opening 150a through which the cable 4 can be inserted. Each grounding member 152 is shown as being provided with a pair of mounting members 154 having a base portion 154a with an aperture 154b. The grounding members 152 can be secured to the rear housing 140 via the apertures 154b with separate fasteners or with material of the rear housing 140 extending through the apertures 154b. Each grounding member 152 is also provided with a sidewall member 156 extending from a first end 156a, proximate the mounting members 154, to second end 156b. As shown, the second end 156b is provided with an outwardly radiused or curved profile to ensure that the cable 4 is not presented to a sharp edge when being inserted past the second end 156b and in a direction towards the central opening 150a. Each of the grounding members 152 is also shown as being provided with a flange member 158 extending away from the mounting member 154 and sidewall member 156. The flange member 158 is shown as extending from a base end 158a adjacent the sidewall member first end 156a to a second end 158b. As shown, the second end 158b is provided with an outwardly radiused or curved profile to ensure that the cable 4 is not presented to a sharp edge when being removed from the grounding arrangement. The flange member 158 extends at an oblique angle from the base end 158a (and at an oblique angle to the longitudinal axis X of the grounding arrangement 150 and cable manager part 20) towards the central opening 150a such that contact with the cable sheath 5 is made when a cable 4 is inserted. The flange members 158 deflect away from the central opening 150a when a cable 4 is inserted and maintain contact against the sheath 5 by virtue of a resulting spring force of the grounding arrangement 150. With the disclosed design, a variety of oblique entry angles (i.e. oblique angle between longitudinal axis of the cable 4 and the longitudinal axis X of the grounding arrangement 150 extending through the center of the opening 50) of the cable 4 can be accommodated by virtue of the grounding member sidewall members 156 being initially larger than the diameter of the cable 4 up to the point that the end of the cable 4 contacts the flange members 158.
In one aspect, the grounding arrangement 150 can be formed from a metal material, such as stainless steel or a copper alloy. Also, each of the grounding members 152 can be formed from an initially flat sheet stock which can be cut and then bent into the shape shown in the drawings. In an alternative embodiment, the grounding arrangement 150 can be integrally formed with interconnected grounding members 152 rather than by separate grounding members 152, as shown in the drawings.
As most easily seen at FIGS. 55-59, the rear housing 140 includes an end wall 140a defining a central aperture 140b. The rear housing also includes sidewalls 142a, 142b, 142c, and 142d which extend from the end wall 140a. Together, the sidewalls 142a-142d and the end wall 140a form an interior cavity into which the grounding arrangement 150 is received. The grounding arrangement 150 is mounted to the end wall 140a such that the central opening 150a of the grounding arrangement 150 is coaxially aligned with the central aperture 140b. As configured, the base portions 154a of the grounding arrangement 150 are supported against the rear housing end wall 140a and are secured to the end wall 140a via protrusions 140c extending from the end wall 140a. The protrusions 140c can be shaped for a snap-fit type connection with the base portions 154a or can be initially formed as posts which are deformed to form a securing cap after the grounding arrangement 150 is mounted. Many other approaches for securing the grounding arrangement 150 to the end wall 140a are possible, for example, mechanical fasteners, soldering, welding, and/or adhesives may be used.
The rear housing 140 is also shown as including projecting sidewalls 142e, 142f which respectively extend from sidewalls 142a, 142b. In one aspect, the connector part 112 and the cable manager part sidewalls 142e, 142f may be configured in a complementary manner, so that the connector part 112 is able to engage with the cable manager part 120 only in one orientation. For example, the recess portion 118b1 on one side of the front housing 118 may be configured with a different size and/or shape than the recess portion 118b2 on the opposite side of the front housing 118. As can be seen at FIGS. 55 and 56, each of the projecting sidewalls 142e, 142f is provided with a different shape corresponding to the recess portion 118b1, 118b2 into which it is intended to be received within. Accordingly, the rear housing 140 can only be fully engaged and connected to the front housing 118 in only a single orientation. To aid in retaining the rear housing 140 to the front housing 118, the front housing 118 can be provided with recesses 118d, 118e which receive corresponding protrusions 144a, 144b on the rear housing part 140 such that a snap-fit type connection is achieved.
The assembled cable manager part 120 with the grounding arrangement 150 mounted to the rear housing 140 can be seen at FIGS. 55-60. At this stage, the cable manager part 120 can be secured to the connector part 112. As noted above, this is accomplished by aligning the cable manager part sidewalls 142e, 142f with the corresponding recess 118b1, 118b2 on the front housing 118. As the two components 112, 120 are brought together, the protrusions 144a, 144b respectively engage with recesses 118d, 118e to secure the front and rear housings 118, 140 together. Because the grounding arrangement 150 is secured to the rear housing 140, the securement of the rear housing 140 to the front housing provides a grounding pathway between the grounding arrangement 150 and the front housing 118.
Referring to FIGS. 59 and 60, the assembled cable manager part 120 is shown with a cable 4 being inserted in an insertion direction D1 through the central aperture 140b of the rear housing 140 and central opening 150a of the grounding arrangement 150. At FIG. 59 (see also FIG. 55), the cable 4 has been inserted up to the point that the flange members 158 contact the end of the outer jacket and exposed sheath 5 of the cable 4. By this position of the cable 4, the individual wires 6, which have been stripped from the jacket and sheath 5, have passed through the openings 140b, 150a. As the cable 4 is further inserted in direction D1, the cable 4 forces the flange members 158 to deflect away from the central opening 150a and a resulting spring force holds the flange members 158 against the cable sheath 5. As can be best seen at FIG. 60, the deflection of the flange members 158 occurs by bending about the base portions 154a proximate the base end 158a of the flange members 158. As this bending occurs, the sidewall members 156 move with the flange members 158 such that their second ends 156b are brought towards the central opening 150a. As the cable 4 becomes fully inserted, the second ends 156b are brought against the cable sheath 5 such that two points of grounding contact (i.e. ends 158b, 156b) between the grounding members 152 and the sheath 15 is established. An additional spring force between the sidewall members 156 and the flange members 158 is created by virtue of resulting bending occurring between the sidewall member 156 and the flange member 158 due to having two point of contact. This additional spring force further secures the cable 4 to the cable manager part 120.
In one aspect, the disclosed cable manager part 120 can accept a cable 4 having a variety of oblique entry angles. Additionally, no active steps are required on the part of the installer to ground the cable to the connector assembly 110 once the cable 4 is properly stripped and inserted into the cable manager part 120. This is in contrast to other designs where a clamp must be actively opened or closed by the installer during insertion. Many materials can be used for the components of the disclosed connector assembly 10.
Many materials can be used for the components of the disclosed connector assembly 10. For example, grounding part 50 can be formed from a metal material, such as plated copper alloy, stainless steel, and/or zinc die-casting.
