The present invention also relates to a control unit for items of clothing having an electrical wiring loom. The present invention also relates to a method of attaching a control unit to a wiring loom included within an item of clothing for use in hazardous environments.
It is known to connect control units to looms contained within items of clothing, as disclosed in US 10,161,611 assigned to the present applicant.
However, problems arise in that many connectors that are generally available for this purpose tend to be either relatively bulky or are intended for semipermanent or permanent connection. Furthermore, problems also arise when part of the connector is attached to a garment that may undergo an industrial washing cycle.

The detailed embodiments show the best mode known to the inventor and provide support for the invention as claimed. However, they are only exemplary and should not be used to interpret or limit the scope of the claims. Their purpose is to provide a teaching to those skilled in the art. Components and processes distinguished by ordinal phrases such as "first" and "second" do not necessarily define an order or ranking of any sort.
BREIF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS Figure 1 shows an embodiment of the present invention, facilitating a method of attaching a control unit to a wiring loom restrained within an item of clothing; Figure 2 shows a wiring-loom plug held securely within a control unit; Figure 3 illustrates the restraining of a control unit within an internal pocket; Figure 4 illustrates a wiring-loom plug; Figure 5 shows an example of a barrel-shaped socket; Figure 6 shows a plug inserted into a socket, such that teeth of the socket have located within indents of the plug; Figure 7 shows an alternative view of a control unit; Figure 8 shows an internal circuit board for the control unit shown in figure 7; and Figure 9 shows a top view of the circuit board identified in Figure 8. DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION Figure 1 An embodiment of the present invention is shown in Figure 1, facilitating a method of attaching a control unit 101 to a wiring loom 102 restrained within an item of clothing 103 for use in hazardous environments. In Figure 1, the item of clothing is a vest but the method may be deployed in other types of clothing, such as jackets, harnesses and trousers etc. Items of clothing of this type are often fabricated from a fluorescent material with strips 104 of light reflective material attached thereto. Often, these strips of light reflective material are located at positions defined by various standards for items of clothing of this type.
The method consists of inserting an insertion end 105 of a wiring-loom plug 106 into a receiving end of a barrel-shaped socket restrained within the control unit 101. The method then continues by pushing the plug 106 into a receiving end 107 of the barrel-shaped socket. The plug is pushed into the barrel-shaped socket, until it is restrained by a restraining portion 108, during which one or more electrical pads secured to the plug 106 slide over one or more spring-loaded pins extending into the barrel-shaped socket, thereby temporarily depressing one or more of these spring-loaded pins.
Figure 2 After insertion of the wiring-loom plug 106 into the barrel-shaped socket of the control unit 101, the wiring-loom plug is held securely in place, as illustrated in Figure 2. The plug includes a grip 201 to facilitate the insertion and removal of the plug from the control unit, with manual force being required to retract the plug in the direction of arrow 202. Thus, if the control unit 101 is released, it will hang freely: supported by the inserted plug and the wiring loom 102.
Figure 3 In an embodiment, as illustrated in Figure 3, after the plug 106 has been fully inserted, the control unit 101 may be restrained within an internal pocket of the item of clothing 103. The control unit may be activated prior to enclosure within the internal pocket but, in an embodiment, it is also possible for activation and deactivation of the control unit to occur when the unit is itself held within a pocket.
Figure 4 The wiring-loom plug 106 is shown in Figure 4, with the wiring loom 102 extending therefrom. The plug 106 may be identified as having an insertion portion 105, a restraining portion 108 and a central portion 401. In this embodiment, the central portion 401 includes a channel 402 with contact pads located therein. In this example, ten contact pads are located within the channel, identified as a first pad 411 to a tenth pad 420. However, alternative configurations of pads are possible. Typically, a minimum of four pads would be required to provide two power cables, a clock cable and a data cable. In the embodiment of Figure 4, an additional six pads are provided to ensure compatibility with existing loom systems and to facilitate further development work.
In the embodiment of Figure 4, the insertion portion 105 is substantially cylindrical, such that this portion may be received within a support orifice in a side wall of the control unit, as described with reference to Figure 7.
In an embodiment, the restraining end 108 is configured to secure an end of the loom 102; to become a permanent fixture of the loom embedded within the item of clothing. As previously described with reference to Figure 2, the restraining end is also configured to define surfaces that facilitate manual insertion into, and removal from, a control unit. Furthermore, although the plug and the control unit provide a complete system, it should be appreciated that a plug forming part of a loom may be inserted within any one of an available set of control units, possible stored within a control-unit-charging device prior to deployment.
It is also anticipated that the life expectancy of items of clothing with plugs attached to looms will be shorter than the life expectancy of control units and, over an operational lifetime, control units may be reprogrammed for use with newly developed items of clothing. Furthermore, programming may occur for deployment within particular environments where, for example, particular light colours for light emitting devices must be adopted. Thus, an aspect of the invention concerns a loom of electrical connectors, for installation within an item of clothing, that includes the plug 106. The plug comprises an insertion portion 105, a restraining portion 108 and a central portion 401. The central portion includes plural contact pads configured to slide over one or more spring-loaded pins upon insertion of the plug within a control unit.
In the embodiment of Figure 4, the loom subassembly includes a strain-relieving support 421 for restraining the electrical conductors. In an embodiment and as illustrated in Figure 2, the restraining portion 108 is configured to define a first external profile that is consistent with a second external profile of a control unit, to present a unified whole when inserted, as described with reference to Figure 2.
In an embodiment, it is possible for the restraining portion 108 to include an optional-functionality circuit. Thus, the optional-functionality circuit may include an electronic gyroscope, additional communication devices (such as those using established low frequency radio protocols) detection devices for detecting the presence of gas or for measuring levels of ambient noise or a battery pack. Consequently, it is possible for generic functionality to be provided by the control unit, with optional functionality being provided by the plug, thereby reducing the cost of an entry-level system.
In an embodiment, the central portion 401 also includes indents for receiving teeth extending from a barrel, as described with reference to Figure 5. In the embodiment of Figure 4, a first indent 431 is provided with a second indent 432; although in other configurations, a different number if indents may be selected. Furthermore, in the embodiment of Figure 4, the second indent 432 is on the opposite side to the first indent 431 but in alternative embodiments, the indents could be provided at different positions.
Figure 5 An example of a barrel-shaped socket is shown in Figure 5, of the type that may be restrained within a control unit of the type described with reference to Figure 1. In this embodiment, the socket 501 includes a first arm 511 and a second arm 512. The first arm 511 includes a first tooth 521 extending therefrom, for insertion within the first indent 431. Similarly, the second arm 512 includes a second tooth 522 extending therefrom, for insertion within the second indent 432.
In this embodiment, the socket includes plural pin holes, each aligned to receive an individual pin. In an alternative embodiment, a shared slot may be provided but the configuration shown in Figure 5 provides extra support for spring-loaded pins during the insertion of a plug. In this embodiment, ten spring-loaded pins engage with respective pads 411 to 420, therefore ten pin holes are provided, consisting of a first pin hole 531 to a tenth pin hole 540. An aspect of the present invention therefore extends to a control unit for items of clothing having an electrical wiring loom, with a plug insertable within the control unit. In particular, a barrel, of the type described with reference to Figure 5, is arranged to present spring-loaded pins, each for making electrical contact with a contact pad of an inserted plug. Furthermore, the spring-loaded pins are configured to be forced to retract upon the insertion of the plug within the barrel, during which one or more contact pads slide over and temporarily depress one or more of the spring-loaded pins.
to Figure 6 Referring to Figure 6, the wiring-loom plug 106 has been inserted into the barrel-shaped socket 501, such that the first tooth 521 has located within the first indent 431 and the second tooth 522 has located within the second indent 432. The insertion portion 105 extends beyond the socket 501.
Figure 7 An alternative view of the control unit described with respect to Figure 2, is shown in Figure 7. The wiring loom 102 extends from the restraining portion 108. The first external profile 422 aligns with a second external profile 701 defined by a restraining cap.
The control unit 101 presents an orifice 702 for receiving the substantially cylindrical extension of the insertion portion 105. Activation and deactivation of the control unit is achieved by manually pressing a large button 703 and the item of clothing 103 may include an indication as to where pressure should be applied to achieve activation of the large button 703 when the control unit is restrained within a pocket; substantially as described in US 10,161,611 assigned to the present applicant. The control unit also includes a visual display device 704, along with a first control button 705 and a second control button 706.
Figure 8 An internal circuit board 801 for the control unit is shown in Figure 8, before application of a front cover. Spring-loaded pins (often referred to as "pogo pins") are inserted into respective holes within the circuit board 801. This embodiment includes ten pins of this type, identified as a first pin 811 to a tenth pin 820. In established use, the bottom of the pins shown in Figure 8 are intended to be soldered directly onto a circuit board and thereafter extend therefrom. Pads are originally intended to be brought into contact with the pins by being moved in an axial direction, substantially perpendicular to the plane of the circuit board. However, in accordance with the present invention, upon insertion of the plug within the socket, as described with reference to Figure 6, one or more of the contact pads slides over and temporarily depresses one or more of the spring-loaded pins, until each spring-loaded pin has established electrical contact with a respective contact pad.
Thus, in this embodiment, the pins are approached in a transverse direction, as indicated by arrow 821, and therefore apply a bending moment when the sliding operation is being performed. Thus, when deployed in a conventional configuration, lateral force would be applied to the pins in this application, which in turn could cause their soldered joints to give way. To avoid this possibility, the pins are effectively inverted and, as an alternative to extending away from the circuit board, holes are created within the circuit board for each respective pin, such that the pins are restrained by these circuit-board holes. Further restraint is then provided by the holes 531 to 540 present within the barrel, as described with reference to Figure 5.
Processing circuitry, to achieve the required functionality of the control unit, is included on the circuit board 801 and a battery for powering the control unit is retained under the circuit board 801 and is therefore obscured in Figure 8.
Figure 9 A top view of the circuit board 801 is shown in Figure 9. Each pin, such as pin 811, extends through a respective hole in the circuit board 801. As previously described, under conventional operation, the pins expect to receive an applied force in the direction of a second arrow 901. However, in this application, the pins initially receive a lateral force in the direction of a third arrow 902, during the insertion of the plug.
During insertion, pins 811 to 820 are depressed and then released between pads until each is brought into contact with its respective pad upon full insertion of the plug. Thus, after insertion, the pins are depressed in the direction of arrow 901 to achieve electrical contact. During insertion, the pins are held in place by holes in the circuit board. Furthermore, the socket includes plural pin holes, as described with reference to Figure 5, with each pin hole receiving one of the spring-loaded pins 811 to 820.
