Description

Connector system with improved unmating functionality

technical field

The present invention relates to a connector system with improved unlocking function for signal transmission. More particularly, the present invention relates to a connector system of a connector and a counterpart, the connector comprising a locking arm pivotally supported and extending towards the counterpart, wherein the locking arm comprises a first locking portion , the first locking portion is adapted to engage with the second locking portion of the corresponding portion by the first rotational movement of the locking arm rotating to the locking position, thereby locking the connector and the corresponding portion, and the second A locking portion is disengaged from the second locking portion by a second rotational movement to an unlocked position to unlock the connector and the corresponding portion.

Background technique

Today, cable connectors such as in telecommunications applications must comply with ever-increasing demands on packaging regarding, for example, robustness, fit quality, aesthetic considerations, density and shielding.

US 4,702,542 discloses a cable connector with a two-part housing that mates and locks with a connector held by another housing. A pivotally supported spring loaded locking arm is provided for locking the cable connector to a mating connector housing or to a cutout in the chassis or board.

A problem with prior art connector systems is that unplugging the cable connector is relatively complicated because the operator needs to first apply an appropriate amount of force in excess of the spring load to activate the latch to unlock the cable connector, and then unplug the cable connector. Unclip the cable connector while still applying force to the latch. If the unplugging operation is not performed immediately after unlocking, the cable connector is locked again due to the spring load on the locking arm.

Connector panels in telecommunication applications typically have hundreds of such connector systems, so repeatedly unplugging the connector systems with such complex motions is ergonomically problematic. Additionally, for panels with a higher density of cable connectors, unplugging is often difficult due to lack of space.

Contents of the invention

It is an object of the present invention to provide a connector system with improved unplugging functionality.

This object is achieved by providing a connector system characterized in that said system is adapted to support said locking arm after said second rotational movement to prevent said locking arm from rotating backwards into said locking position. By providing the system with means for supporting the locking arm in the unlocked position while the cable connectors are not unplugged, the operator can first unlock the connectors from the counterpart and later unplug or separate them at a convenient time . The locking system according to the invention no longer requires complicated actions to unplug the connector, such as unplugging the cable connector from the corresponding part, eg the board connector housing or the board. In addition, when the cable connector is applied to many cables, the space to grasp the cable connector is limited. The present invention allows the cable connector to be unlocked first by actuating the locking arm and then unplugged by pulling on the easily accessible cable. It should be noted that the connector system according to the present invention can be applied in various situations, including between a cable connector and a board connector housing, between a cable connector and another cable connector, between a board connector and another A connection between a board connector and so on. It should also be noted that signal transmission may involve electrical and optical signals. It should also be understood that the locking arm could be part of the corresponding part, ie the reverse would be the case when changing the connector to the corresponding part and vice versa. For example, if the locking arm is part of the board connector housing rather than the cable connector, the locking arm is less susceptible to mechanical shock.

In an embodiment of the invention, the connector system comprises a support structure supporting said locking arm. Such support structures may be provided in the connector and/or in the corresponding part. The support structure is a reliable means of preventing the locking arm from rotating backwards into said locked position. Preferably the locking arm comprises a portion bent in the direction of said support structure, so as to ensure that the locking arm contacts the support structure after unlocking.

In an embodiment of the invention, the locking arm is formed in contact with said corresponding portion. The contact between the metal locking arm and the corresponding part can improve the electromagnetic shielding effect.

In an embodiment of the invention, the connector system includes a spring member for applying a biasing force to said locking arm to urge said locking arm to remain in said locked position. If the connector is inserted into the counterpart, the spring member provides an automatic locking action of the locking arm without manual actuation of the locking arm. The spring member can be integrated with the locking arm and constitute, for example, a torsion spring, a helical spring or a helical spring. The spring member may alternatively be an additional, separately mounted component. Such a separate spring member is advantageous since the locking arm can be of a different material than the spring member so that the two elements can be optimized for their respective purposes. For example, if higher spring forces are required, the spring component structure can be optimized for this without being limited by the requirements placed on the locking arm. The spring member also returns the locking arm to its original position if the system is unplugged. Furthermore, the internal loading of the locking arm may provide an audible click if, for example, the connector supported by the support structure locks into the corresponding part. In an embodiment of the invention, a spring member may also be used to exert a biasing force perpendicular to the plane of said first and second rotational movement. By locating or constructing the spring member so that it exerts a spring force in the rotational direction and laterally, the locking arm can contact the support structure without requiring the locking arm to have a special shape. Additionally, lateral forces can be used to eliminate backlash in the system.

In an embodiment of the invention, the first locking part comprises a hook with a first locking surface, said second locking part comprises a second locking surface for pressing against said first locking surface in said locked position . Further the second locking part may comprise a ramp surface for guiding the guide surface of said first locking part at least prior to said first rotational movement. This locking configuration has been proven to provide reliable automatic locking.

In an embodiment of the invention, a locking arm protrudes from the housing of said connector to guide said second rotational movement. Extension of the locking arm enables manual actuation of the locking arm. Optionally, the connector includes a housing for exposing said locking arm in a manner enabling said locking arm to guide said second rotational movement. The housing may, for example, include a hole for inserting a tool, such as a screwdriver. Preferably the locking arm is actuatable by means of a structure which converts a rotational movement of the screwdriver into an actuation of the locking arm. Indeed, the rotational movement of the screwdriver requires only a small amount of space for the operator to operate on a high-density board. In addition, the non-protruding locking arm reduces the chance of unintentional unlocking.

In an embodiment of the present invention, wherein the housing of the connector comprises a first space having an entrance for cable entry and a second space accommodating a part of said locking arm. The second space is preferably intended to contain the shaft of the pivotally supported locking arm or for the shaft of the locking arm. The separate second space can protect the locking arm, especially when covered or closed by one or more walls.

In an embodiment of the invention, at least one of said connector and said corresponding portion and said locking arm is metal. Metal elements provide increased stiffness to the system and improve the electromagnetic shielding effect compared to plastic housings. The locking arm may be or include stainless steel. Stainless steel can be stamped or otherwise proved to have the proper combination of stiffness and spring function properties.

In an embodiment of the invention, the counter part comprises a sheet metal connector housing mounted on a printed circuit board and having an entrance for said locking arm into a receiving space comprising said second locking part. While the locking arm may lock the cable connector to the board, for the purposes of the present invention it is preferred that the locking arm lock the cable connector to the housing of the board connector to avoid changes to the board. The receiving space may also include the support structure and at least one of the locking surface and the ramp surface. For sheet metal connector housings, die-cast materials can be used, for example. Die-cast materials offer considerable latitude for conforming board connector housings to locking requirements. However, while die cast material is the preferred material, other materials than die cast, plastics, and metallized plastics may also be used, for example.

In an embodiment of the invention, the board connector housing inlet includes one or more ground springs surrounding said inlet. The ground spring improves the electromagnetic shielding effect of the board connector housing when the connector is unlocked or unplugged. Additionally, the inlet may include one or more chamfered guide walls to facilitate insertion of the lock arm.

In an embodiment of the invention, the board connector housing has a mating side of said connector, said mating side comprising at least one threaded hole. The threaded holes allow conventional cable connectors without pivotally supported locking arms to lock onto the board connector.

In an embodiment of the invention, a connector system is used to allow operation of said locking arm to re-rotate into said locked position. This can be achieved, for example, by having a support structure comprising an obliquely oriented support surface, or by allowing the locking arm to move sideways thereby allowing said locking arm to re-rotate into the locked position. Such an embodiment is advantageous because it is not necessary to first at least partially unplug the connector before relocking.

The invention also relates to a cable connector for use in a connector system as described above.

The invention also relates to a counterpart, preferably a board connector housing for use in a connector system as described above.

The invention finally relates to a method for unplugging a connector from a counterpart, said connector having a pivotally supported locking arm extending towards said counterpart for locking said connector and said counterpart, The method comprises the steps of:

- unlocking of said connector by rotational movement of said locking arm from a locked position to an unlocked position;

- having said connector in an inserted position, and said locking arm in said unlocked position without exerting an actuation force on said locking arm;

-then unplugging said connector from said counter part.

US 5,628,648 discloses a connector positioning assurance system in which an electrical connector includes a main locking arm with a locking slider mounted on top of the locking arm. The locking arm is locked by sliding a locking slider on the locking arm. In the unlocked position, the main locking arm is able to rotate. However, the disclosed system is a complex locking system and does not prevent the locking arm from rotating back into the locked position.

US 5,154,629 discloses a cable connector in which side cavities pivotally receive latches having locking fingers for engaging connecting elements and are biased to the Lock position. The latch however requires additional sliding movement in the lateral direction and provides no support for the latch in the unlocked position.

Detailed ways

Although the present invention relates to including a connector for signal transmission and corresponding parts, a connector system including a cable connector and a board connector housing will be described in detail next.

1-3 show an I/0 cable connector system 1 comprising a cable connector 2 with a cable 3 and a board connector housing 4 . The front panel 5 has a cutout 6 for insertion of the cable connector 2 . The front panel comprises a circuit board 7 hereinafter also referred to as PCB 7 . The PCB 7 generally includes a number of signal tracks and electronic components (not shown) for transmitting electrical signals to or from one or more wires of the cable 3 . The connection of these lines to the signal tracks of the PCB 7 is obtained by providing a header arrangement (not shown) within the board connector housing 4 .

The cable connector 2 comprises parts described in detail in the applicant's pending patent application NL1022225 ("Cable connector and method of fitting a cable to such a cable connector"). This application is incorporated by reference in this application with respect to the features and structure of the module die-cast metal housing parts 10, 11 and with respect to the cable 3 and the connection of the wire end of the cable 3 to the cable connector 2, wherein the module die-cast metal housing The parts 10, 11 provide a first space for the cables 3, a die-cast metal base 12 and a sheet metal part 13, as shown in Figures 2A and 2B.

The board connector housing or shield 4 comprises a die-cast metal part 14 and a metal plate part 15 similar to the shield described in detail in the applicant's pending patent application NL1023662 ("Shield"), with respect to the structure of the metal plate part 15 This application is incorporated in this application by reference, both as regards the manner in which the sheet metal part 15 is attached to the die cast metal part 14 . Additionally, the pending application provides information for mounting die cast metal portion 14 onto PCB 7.

The cable connector 2 comprises a locking arm 16 with a first locking portion 17 pivotally supported by a pivot joint 18 extending towards the board connector housing 4 and protruding from the cable connector 2 The locking arm 16 is thus guided in a rotational movement about the pivot joint 18 . The pivot joint 18 may be formed by fasteners such as screws, snap joints, pins, or other suitable forms of connection. The locking arm 16 may have an expanded pressing surface S for manual operation. A cover 19 is attached to the cable connector housing portion 11 to provide a second space for receiving a portion of the locking arm 16 . Cover 19 may be attached to housing part 11 by pivot joint 18 . The pivot joint 18 may be incorporated into the cover 19 . The locking arm 16 is preferably stainless steel. Stainless steel can be stamped and has proven to be a suitable combination of stiffness and resilience characteristics.

It should be noted that, alternatively, the cable connector 2 comprises a housing for exposing the locking arm 16 so that said locking arm 16 can guide the rotational movement. The housing may, for example, include a hole for inserting a tool, such as a screwdriver. Preferably the locking arm 16 is actuatable by a structure (not shown) that converts the rotational movement of a screwdriver into actuation of the locking arm 16 . The rotary movement of the screwdriver does require very little space for the operator to operate on a high-density panel.

FIG. 3 shows a perspective view of the board connector housing 4 . The board connector housing part 14 has an inlet 20 for the locking arm 16 into the receiving space 21 . The receiving space 21 has a second locking portion 22 for engaging with the first locking portion 17 of the locking arm 16 by a rotational movement of the locking arm 16, which will be described in more detail below. The receiving space 21 also includes a support structure or ledge 23 . The function of the support structure 23 will be described in further detail below. The inlet 20 includes a ground spring 24 surrounding said inlet 20 . The grounding spring 24 can improve the electromagnetic shielding effect of the board connector housing 4 when the cable connector 2 is unlocked or unplugged. Additionally, the inlet 20 may include a chamfered guide wall 25 to facilitate insertion of the locking arm 16 . The board connector housing 4 may also include at least one threaded hole 26 . The threaded holes 26 allow conventional cable connectors without pivotally supported locking arms 16 to be locked to the board connector 4 . It should be understood that the board connector housing 4 could also be a one-part housing formed of die-cast metal or any other type of convenient material. It should be noted that the chamfered guide wall 25 can be placed backwards or even omitted so that the board connector housing 4 has a single entry for the cable connector 2 and the locking arm 16 . In such an embodiment, the cable connector 2 may comprise elements forming said walls when the cable connector 2 is inserted into the board connector housing 4 . This embodiment is advantageous, for example, because the elements for the cable connector can further protect the locking arm 16, while the adapted access to the board connector housing can improve the electromagnetic shielding effect.

Figures 4A, 4B and 5 show detailed views of the connector system 1 in the inserted and locked state. Fig. 4A shows a top view of the connector system 1, while Fig. 4B shows a top view of the area delimited by dashed lines in detail.

The locking arm 16 has a first locking portion 17 in the form of a hook with a guide surface 30 and a first locking surface 31 , as shown in FIG. 2A . The lock arm 16 is formed to be in contact with the board connector housing 4 . If this internal spring function can provide sufficient force between the locking arm 16 and the board connector housing 4, then the support structure 23 shown in FIG. 3 can be omitted. In addition, the contact between the metal locking arm 16 and the housing 4 can improve the electromagnetic shielding effect. The bold arrows in FIG. 4B show the force on the locking arm 16 . F1 is the expected preload exerted by the shape of the locking arm 16 on the mated connector surface. F2 and F3 are reaction forces. F2 can be adjusted eg by tightening or loosening a screw. Due to tolerances and friction in the desired function of the locking arm 16, it can be optimized by adjusting the preload.

FIG. 5 shows a detailed perspective view of a portion of the connector system 2 in the inserted and locked state in FIG. 2B , with the cover 19 of the cable connector 2 and the cover of the board connector housing 4 omitted for clarity. side wall. Only a small part of the support structure 23 is visible because it is blocked by the front of the locking arm 16 .

The locking arm 16 has a hook portion 17 with a guide surface 30 and a first locking surface 31 for pressing against a second locking surface 32 of the second locking part 22 in the locked position. The second locking part 22 also includes a ramp surface 33 for guiding the guide surface 30 of said first locking part 17 when the locking arm 16 is inserted into the entrance 20 of the receiving space 21 . The lower part of the hook portion 17 can be bent towards the board connector housing 4 along the dotted line B, thereby ensuring that the locking arm 16 can be supported by the support structure 23 .

Additionally, the locking arm 16 includes an integrated spring member or bias spring 34 for applying a biasing force to the locking arm 16 to urge said locking arm to remain in the locked position shown in FIG. 5 . The spring member 34 is supported in the second space defined by the connector housing part 11 and the cover 19 . If the locking arm 16 is pulled out as shown in FIG. 4B , the spring member 34 can also return the locking arm 16 to its original position. Furthermore, the internal loading of the locking arm 16 may provide an audible click if, for example, a connector supported by a support structure locks into a corresponding part. As previously mentioned, the spring member 34 may also be a separate spring member 34 for the locking arm 16 .

The spring member may also be used to exert a biasing force F4 perpendicular to the plane of the first and second rotational movements R1 and R2 (see Figures 8 and 9). By locating or configuring the spring member 34 so that it exerts a spring force both in the rotational direction and in the lateral direction, the locking arm 16 can contact the support structure 23 without the need for an internal preload. Additionally, lateral forces can be used to eliminate backlash in the system.

An example of the operation of the connector system 1 is shown in Figures 6-11. Like reference numerals are used to identify like parts of the connector system 1 .

6A-6C show in detail a plan view of the connector system 1 prior to insertion of the cable connector 2 and board connector housing 4 . The locking arm 16 has a position determined by the spring member 34 so that the guide surface 30 can follow the ramp surface 33 of the second locking part 22 during insertion. Clearly, the locking arm 16 is bent towards the board connector housing 4, as shown in the enlarged top view in FIG. 6A.

7A-7E show in detail plan and perspective views of the connector system 1 during insertion of the cable connector 2 and board connector housing 4 . Clearly, the guide surface 30 follows the ramp surface 33 while the locking arm 16 rotates about the pivot joint 18, as best shown in Figures 7C and 7D. During insertion, the insertion rotation of the hook portion 17 of the locking arm 16 is deflected outward as the sidewall of the board connector housing 4 presses the flexible locking arm 16 in this direction, as best shown in FIG. 7E . It is clear in FIG. 7D , which shows that the side walls of the support surface 23A of the support structure 23 are raised relative to the flat portion 33A of the ramp surface 33 so that the guide surface 30 does not protrude beyond the support surface 23A at this stage.

If the hook 17 passes the last substantially flat portion 33A of the ramp surface 33, the locking arm 16 undergoes a first rotational movement R1 in which a second locking of the hook 17 with the board connector housing 4 Part 22 engages into a locking position to lock said cable connector 2 . 8A-8C show in detail plan views of the connector system 1 in this locked state. It is clear that the hook 17 of the locking arm 16 is deflected outwards. The spring member 34 exerts a spring force on the locking arm 16 to hold the locking arm in the locked position. From the above it is clear that the locking of the connector system can be done by insertion by the operator using only one hand.

If the cable connector 2 and the board connector are to be unplugged, the first locked position is canceled. 9A-9D detail plan and perspective views of the cable connector and board connector housing after unlocking and before unplugging. For example, by manually operating the protruding portion of the locking arm 16 to guide the locking arm 16 to generate the second rotational movement R2 to disengage the hook portion 17 from the second locking portion 22 . The shape of the locking arm 16 and/or the hook portion 17 ensures that the locking arm 16 is supported by the support structure 23 after said second rotational movement R2 and prevents it from rotating backwards into the locked position as shown in Figs. 8A-8C. A ledge 23 is preferably bounded by the board connector housing 4 adjacent to and spaced from the second locking portion or protrusion 22 and the ramp surface 33 .

By providing the system with means for supporting the locking arm 16 in the unlocked position when the cable connector 2 has not been unplugged, the operator can first unlock the cable connector 2 and then unplug or separate at a later convenient time. they. Therefore, the locking system according to the present invention does not require complex operations for unplugging the cable connector 2 from the board connector housing 4 or the panel 5 as described above.

10A-10D show in detail plan and perspective views of the connector system during unplugging of the cable connector 2 and board connector housing 4 . It is clear that the hook 17 is guided by the support surface 33A so that the first locking surface 31 passes over the second locking surface 32 , thus avoiding relocking. In order to establish a subsequent locking, the cable connector 2 and the board connector housing 4 should in this embodiment be unplugged at least to the stage where the hook 17 is no longer supported by the support surface 33A. The hook 17 is no longer deflected outwards.

Finally, Figures 11A-11D show in detail the connector system 1 in plan and perspective views during further unplugging of the cable connector and board connector housings. In this state, the guide surface 30 of the hook portion 17 follows the ramp surface 33 while the locking arm 16 is urged by the spring member 34 to rotate about the pivot joint 18 .

The locking arm 16 can be attached to the first connector 2 or the second mating connector 4 or the board 5 . Similarly, the second locking portion 22 , the ramp surface 33 and the ledge 23 may be delimited by the first connector 2 or the second mating connector 4 or the plate 5 . Once mated, the first and second connectors 2 and 4 can resist large forces such as 120N, typical twisting, bending and pulling tests without unlocking.

It should be noted that the various features of the connector system 1 described above may be modified within the scope of the invention, for example as shown in Figures 12A and 12B. In this embodiment, the connector system 1 is arranged such that relocking can be performed without having to unplug the cable connector 2 . The ledge surface 23A' of the ledge 23 forms an angle α with respect to the horizontal of the support surface 23A shown in FIG. The hour hook 17 can slide from the ledge surface to the locked position. The angle α can be varied to optimize the force used to return the locking arm 16 to the locked position either inadvertently or intentionally. It should therefore be noted that in the embodiment of FIG. 12, the feature of the invention which prevents the locking arm 16 from rotating backwards into said locked position should be interpreted as substantially preventing the locking arm from rotating backwards, since in this embodiment the locking arm 16 16 may re-rotate to the locked position under anticipated action. It should be understood that other embodiments performing this re-locking function are contemplated in which the locking arm 16 includes a flange corresponding to a recess, hole or slot in the support structure 23 . At the same time the system 1 can be used to allow the locking arm 16 or at least the hook 17 to move sideways so that the hook 17 clears the support structure 23 and the locking arm 16 is rotated back into the locked position.

In addition, it should be noted that other modifications of the illustrated embodiment should fall within the scope of the invention, these include embodiments in which the locking arm 16 is mounted on the board connector and an additional spring member 34 is applied, Embodiments where the board connector housing 4 comprises only a single space for the cable connector 2 and the locking arm 16, and where more than one locking arm 16 is used for the connector system 1 to be mounted on a single cable connector 2, for example the embodiment.
