Definitions

  • the present invention relates to a connector and a method of manufacturing a connector and, more specifically, to a plug connector comprising a button for operating a latch and a method of manufacturing such a connector .
  • connectors In the field of connectors, there is an ongoing strive towards smaller, compacter, cheaper and more robust connectors. Further, connectors tend to become more complex, e.g. by being provided with additional elements such as button operable switches or lights etc. These trends have to compete with maintaining relatively low manufacturing costs and preferably reducing them.
  • a manually operable latch renders the construction and manufacture of a connector more complex, more expensive and possibly more fragile than a connector without such a mechanism does. Consequently, there is a need for a robust connector with a button operable element such as a switch, or a latch, which is relatively simple and inexpensive in construction and manufacture .
  • a connector which comprises a connector body with a connection means block having one or more connection means.
  • the connector further comprises at least one button operable element, such as a switch or a latch, and a button arranged for operating the element.
  • the terminal block is at least partially overmolded with a material forming at least a partial connector body cover.
  • the button is separately attached to the connector body cover, advantageously on the outside thereof .
  • An overmolded cover of a connector provides an electric insulation of the connector body to the outside and facilitates the manufacture of the connector. Further, the cover may shield the connector body against dirt, gas and/or liquid.
  • overmolding techniques allow realising highly diverse shapes and structures for the cover.
  • the overmolding material may not only form a partial or complete connector body cover but may also provide a strain relief when one or more cables are attached to the terminal block.
  • the button, being separately attached to the connector body may be attached to the connector body without being covered and/or immobilised by the overmolding material.
  • the connector may be adapted to accommodate diverse connection means such as optical ferrules, for transmitting optical signals or contact terminals for transmitting electrical signals.
  • both parts, the connector body and the button may be optimised for distinct properties, such as reliability, process economy, material economy and/or aspects of user-friendliness such as colour and/or texture.
  • the connector may be formed according to claim 2.
  • the embodiment defined in claim 3 provides a robust and relatively easy to manufacture connector, since in such a connector, the potted elements of the terminal block and other connector body parts may be substantially immobilised and enclosed tamper proof in a substantially solid piece of material.
  • Particular potting techniques in which voids of an object are filled in a mold with a, preferably substantially fluid material which is let set and solidify, allow to realise and maintain connection means by pressing the contacting parts together during the molding whereafter the relative position of the contacting parts is fixed inside the potting material.
  • Claim 4 defines a particularly robust and simple connector, since essentially the entire connector body is a substantially solid object and undesired relative movement of different parts of the connector is prevented. Overmolding and/or potting molds may be such that the resulting shape of the objects is readily usable for a further assembly process or for vending to customers without requiring post-processing such as milling and turning etc.
  • the embodiment defined in claim 5 does not require additional parts or elements for attaching the button and the connector body to another.
  • the embodiment may easily be realised by virtue of the freedom of design granted by overmolding.
  • An efficient, easily made and reliable connector is defined in claim 6.
  • a further benefit of such a connector is that in case of malfunction of or damage to the button, the button may be removed and the button-operable element may still be operated. Further, a defective button may be replaced without having to replace the entire connector, possibly an attached cable and relatively expensive elements inclusive.
  • the connector body cover and the button may be provided with a ridge behind which the button may snap which is chamfered or filleted.
  • additional force for biasing elements used for snapping is not required and the manufacture of the connector is rendered relatively simple and reliable.
  • the connector may therefore be relatively inexpensive.
  • the button may be of various types, e.g. a lever rotatably attached with a pivot to recesses or eyes etc. in the plug body cover forming a rocking button, a further embodiment is defined in claim 7. This embodiment allows forming both the outer cover of the connector body and the button relatively simply, since a relative position of the button and the connector body may be well defined and the button may even effectively be attached to the connector body in at least one direction by clasping it.
  • a connector according to claim 8 may provide a physically secure connection between the connector and a counterpart.
  • the latch may be located anywhere in or on the connector body and its cover, but should comprise parts for engaging a counterpart.
  • the latch may be attached to or form part of the terminal block and it may be partially or completely covered by the overmolding material.
  • the connector may have a single latch or two or more latches, whereas at least one of the latches may be operable by means of the button.
  • the connector body With a connector defined in claim 9 the connector body needs only be designed to provide an exposed part of the button operable element.
  • the exposed part may e.g. be formed by not covering or uncovering a part of the latch by the overmolding and/or potting material.
  • the button and (the exposed parts of) the connector body may thus be shaped to form cooperating structures for the operation of the element.
  • the connector body may be a substantially solid object from which protrudes a movable part of the button operable element.
  • the button operable element may also be partly embedded in the connector body.
  • the exposed part may be relatively small.
  • a connector defined in claim 10 provides a reliable latch, since a biased latch is capable of returning to its previous position after operation. Further, the biased position may be accurately determined by the position of parts of the final product or during assembly of the final product, allowing less stringent tolerances on (the manufacture of) the constituent parts of the connector.
  • the connector may be formed according to claim 11. This also allows operating separate button-operable structures and/or multiple latches independently.
  • a connector which comprises a connector body with a terminal block having one or more terminals such as for connecting wires thereto.
  • the connector body has at least one latch for securing the connector body to a counterpart.
  • the connector further comprises a button arranged for operating the at least one latch.
  • the terminal block is at least partially overmolded with a material which forms at least a partial outer cover of the connector body, and which leaves one or more parts of the latch exposed.
  • the button is separately attached to the connector body cover, preferably to the outside thereof, and is arranged for engaging at least one of said exposed parts of the latch for the operation thereof.
  • a connector comprising a connector body with a terminal block having one or more terminals such as for connecting wires thereto, and with at least one latch for securing the connector body to a counterpart.
  • the connector body further comprises a button arranged for operating the at least one latch.
  • the terminal block is at least partially overmolded with a material forming at least a partial outer cover of the connector body, and which leaves one or more structures of the latch exposed.
  • the button is separately attached to the connector body cover and attached thereto by means of a snap-fit and is arranged for engaging at least one of said exposed structures of the latch for the operation thereof.
  • the connector may be easily assembled from separately manufactured connector body parts and button parts without having to revert to additional fastening means and/or elements.
  • the connector may be manufactured relatively inexpensively.
  • a method for the manufacture of a connector according to any one of claims 14-22 is provided.
  • the elements of the connector body and the button thus may be provided as separate parts.
  • the manufacture process, material or materials, shape etc. of the connector body and its cover as well as the button may therefore be optimised independently.
  • a method is provided for obtaining a relatively inexpensive connector with a button operable element.
  • the step of attaching the button to the connector body cover may be the final step in the assembly of the connector. This allows performing tests on the connector body beforehand and to optimise the manufacture process of both connector body and button separately.
  • the method allows forming a cover tightly and reliably around the terminal block according to substantially any moldable shape. Further, elements such as a strain relief for a cable attached to the connector body may be integrally formed.
  • the method of claim 15 allows to produce a substantially solid and robust connector body, and at the same time to fix parts of the connector to other parts.
  • the method of claim 16 combines the benefits of potting and overmolding in one integrated (overmolding) step, such that no separate overmolding sleeve may be required but that the potting material may form the connector body cover.
  • the shape of the overmolding and/or potting material is generally determined by the mold and particular predetermined parts may be left uncovered and exposed. Voids or cavities may be realised underneath an overmolded cover by overmolding a sleeve around the object. Generally, however, such cavities result in weak spots in the cover and frequent flexing or other forms of wear may cause rupture thereof. In case of potting, intended cavities and movable parts may be hard to provide within the potted volume. Similarly, in a hard shell cover of a connector body, a perforation inherently presents a weak spot in the cover. The method of claim 17 obviates the requirement of providing such cavities or openings for the button, since part of the button operable element may generally be exposed. In particular a latch should be at least partially exposed in order to operably engage the connector counterpart, thus the connector may be easily provided with a latch.
  • the button may be attached in a straightforward and generally simple manner according to the method of claim 18.
  • the method of claim 19 facilitates manufacturing the connector.
  • the method may be employed to set or adjust at least a part of the button operable element, e.g. a latch, to a predetermined position, e.g. establishing a bias force, such that even with non-optimally assembled parts or parts conforming to relatively less stringent tolerances may be used for the connector. It also allows assembling the connector along guiding structures which may be optimised for the assembly step, but which may not be required for operation of the button.
  • the method according to the invention may further allow to form a robust connector using straightforward overmolding techniques and to provide it with a manually operable latch as well.
  • the method according to the invention may also allow rendering the manufacture of a connector with a button-operable latch relatively easy and straightforward.
  • the method according to the invention may also allow manufacturing an overmolded connector with a manually operable latch, which may be designed in various shapes and be made of various materials.
  • the method according to the invention may be executed such that at least one structure of the latch is biased to a predetermined position, which allows the final product to be reliable in operation and to conform to tight tolerances.
  • the present connector and method of manufacture thereof allow a button operable element, such as a switch or a latch, to be formed of various designs and with relatively small structures, since the button may provide a convenient contact surface for manual operation and which can be attached in a final manufacturing step.
  • a connector may be provided with added customer attractiveness and/or user friendliness by coloring and texture effects, reducing stress on the equipment and thus prolonging its lifetime.
  • the connector may have a manually operable latch allowing a relatively high retention force.
  • the present connector may maintain the robustness of a basic connector, especially an overmolded one.
  • a connector with a latch may require only one additional part relative to a connector having a passive (not operable) or an immobile latch.
  • the same design of the connector body cover may be used for a passively lockable connector having just friction lock structures.
  • Figs. 1-7B show views in perspective of various steps of a method of manufacture of a connector body.
  • Figs. 8A-8D show different views in perspective of a button for the connector of Figs. 1-7B.
  • Figs. 9 shows a view in perspective of a method of manufacture a connector by assembling the connector body and the button of Figs. 1-7B and 8A-8D, respectively.
  • Fig. 10 shows an embodiment of the assembled connector.
  • Fig. 11 shows a receptacle for use with a connector according to Fig. 10.
  • Figs. 12A-12C show the mating and unmating of a connector and a receptacle.
  • Figs. 1-10 show a plug connector according to the invention and a method of manufacture thereof.
  • Fig 1 shows a cable 1 comprising an insulating sheath 2, a shielding braid 3, and a plurality of wires 4.
  • Fig. 2 shows a terminal block 5 having a plurality of terminals 6 for connecting wires 4 thereto. It further has two latch arms 7 each provided with a latch protrusion 8 and a protruding portion 9, the function of which will become apparent later.
  • the terminal block 5 has a mating side or front side FS and a rear side RS opposite the front side.
  • a first step of manufacturing (Fig. 1), the sheath 2 of the cable 1 is stripped over part of its length and the shielding braid 3 is folded back over the sheath 2, exposing the wires 4. Then, (Fig. 2) the wires 4 of the cable 1 are connected to the terminal block 5.
  • the cable is connected to the rear side RS of the terminal block 5.
  • the latch arms 7 are resilient and may be, but not necessarily, conductive, e.g. such as being stamped or cut from relatively thin beryllium copper sheet.
  • the latch arms 7 may be integrated in the structure of the terminal block or be separate parts.
  • the terminal block 5 may be provided with any suitable number or design of latches 8 or latch arms 7.
  • Fig. 3 shows, as a further optional step of manufacturing, in which the rear portion of the terminal block 5 is potted with a molding material forming a first overmoulding part 10, which has a flange 11 at its rear side.
  • the first overmoulding part 10 covers the connection of the wires 4 to the terminals 6.
  • the wires and the connections are to a certain extent protected against outside influences and against mechanical stresses and forces.
  • the first overmoulding part may be used to press-connect the wires 4 to the terminals 6, in ways known in the art, obviating soldering of the connections.
  • a portion of the latch arms 7 comprising the latches 8 and the protrusions 9 is movably exposed by the first overmoulding part.
  • Fig. 4 shows, as another step of manufacturing, the terminal block of Fig. 3 being covered with a front shield 12, such that the connector body 13 may be seen to take shape.
  • the front shield 12 comprises a relatively flat portion at its front side, at least a part of which forms a mating portion, and a relatively wide portion at its rear side, which fitsover the first overmoulding part 10 and abuts the flange 11 thereof.
  • the shield 12 leaves at least a portion of the latches 8 and of the protrusions 9 movably exposed.
  • a preformed shield 12 may be mounted, e.g. by sliding, onto the terminal block 5 from the mating or front side FS thereof.
  • the shield 12 mechanically protects the terminal block 5.
  • a conductive shield 12, e.g. made of metal, also shields the terminal block 5 against electromagnetic noise.
  • Figs. 5 and 6 show manufacturing steps, following the step of Fig. 4, wherein a portion of the shielding braid 3 is folded forward over the shield 12 (Fig. 5) and the rear part of the connector body and the front portion of the cable are provided with a covering material.

  • Figs. 7A-7B show two views of the connector body 13 provided with a connector body cover 15 which substantially determines the outer shape of the connector body 13.
  • the connector body cover 15 covers a portion of the shield 12, leaving at least another portion thereof exposed.
  • the connector body cover 15 has been applied as a second overmoulding part 16, exposing a mating section and (the access to) the movable parts of the terminal block 5.
  • the overmoulding part 16 comprises a strain relief section 17, a main section having a gripping feature 18 and a button mounting section 19.
  • the button mounting section 19, which here is recessed with regard to the upper and side walls of the connector body cover 15, has an upper groove 20, a ledge 21 and side grooves 22 on either side, the functions of which will be explained in the following.
  • the shape may be determined in essentially a single manufacturing step.
  • overmolding material need only be applied to parts of the connector body covered by a closed part of the shield 12, thus preventing overmolding material from entering the interior of the shield and immobilising parts. Therefore, relatively simple and cost efficient molds may be used.
  • Figs. 8A-8C show various perspective views of a button
  • the button 23 having an upper plane 24 and two legs 25 on either side of the upper plane 24.
  • the button 23 has a substantially U- shaped cross-section, clearest visible in Fig. 8B.
  • the upper plane 24 is divided in a rear portion 26, fixed to the legs 25 and an actuating portion 27 which is movably attached to the rear portion 26.
  • the button is further provided with two ribs 28, 29.
  • the front rib 28 is arranged on the actuating portion 27 and the rear rib 29 is arranged on the rear portion 26.
  • the legs 25 are each provided with a side ridge 30 on the inside of the button 23.

  • the button 23 and the connector body 13 may be slid onto another from the mating side of the connector (see the bold arrow in Fig. 9), such that the side ridges 30 of the button 23 fit into the grooves 22 of the connector body cover 15 and the rear rib 29 of the button 23 snaps into the groove 20 behind the ledge 21 of the connector body 13.
  • Ledge 21 and rib 29 are chamfered to facilitate mounting the button to the connector body 13.
  • the button 23 may be snapped to the connector body 13 from the top thereof (not shown) .
  • the front rib 28 is arranged for engaging the protrusions 9 and depressing them (deeper) into the shield 12 thus operating the latches 8.
  • the button 23 should thus be shaped and/or dimensioned to be attached to the connector body 13 such that at least the actuating portion 27, possibly the entire button 23, is movable with respect to the connector body 13 and engaging, or at least engageable to, the button operable elements of the connector.

  • the tolerances of the second overmoulding part 16 with regard to the shield 12 may be relatively small, due to the shape and stiffness of the overmolding mold. Similarly, the tolerances for manufacturing the button 23 may be relatively small. Thus, the button 23 and the connector body cover 15 may be manufactured to relatively tight tolerances with respect to another .
  • the front rib 28 may engage the protrusions 9 with some force, such that the latching arms 7, and thus the latches 8, are biased, improving reliability of the repositioning of the latches 8 after their operation. It also allows relatively large tolerances for manufacturing the movable elements of the connector body such as the latches 8, latch arms 7 and/or their mounting to the terminal block 5 and shield 12. Application of the bias force during assembly of the connector is facilitated by chamfering or filleting the rib 28.
