Abstract

A connector comprises a body 12 and a push-on connector ring 16 for securing to a female connector 42. A locking ring 18 held by the body is movable relative to the push-on connector ring to lock it in position. This allows a push-on connector to be locked firmly to a female connector, typically associated with an electrical device, so as to obtain the screening (electromagnetic leakage) specification of a push-on connector but the locking specification of a screw connector. The body comprises a shaft portion 14 along which the push-on connector ring slides. The locking ring is pushed in one longitudinal direction along the shaft to engage with the push-on connector ring and lock it to a female connector, and is pushed along the shaft in the other direction to disengage from the push-on connector ring and release the female connector. The locking ring and push-on connector ring are preferably provided with an interengaging ridge 36 and channel 28 capable of locking the locking ring and push-on connector ring in a fixed position with respect to each other. The inner surface of the push-on connector ring may have a threaded portion 24, and channel 28 may be coloured red.

Description

Title: Cable Connector
Field of the invention
This invention relates to a cable connector such as is used to mount a cable onto a female connector associated with a device.
Background to the invention
Cable connectors are joined to the end of cables so that the cable can engage with a connector on an electrical device. Normally a male connector is secured to the cable, io with a female connector on the device. To mount the cable to the device, the male connector is screwed or pushed on to the female connector. With screw connectors, it is very important that the male connector is screwed with the correct torque to the female connector as otherwise the connection is not sufficiently secure to prevent electromagnetic signals leaking from the device or external signals entering the device is and introducing noise into the electrical system. With push-on connectors, a spring grips around the female connector on the device and closes the gap between the female connector and the male connector to stop leakage of electromagnetic signals.
However often the connectors become separated as they are only secured by a push-on connection.
Summary of the invention
n accordance with the present invention, there is provided a cable connector comprising a body joined to a connector element securable to a mating connector, wherein a locking element associated with the body is movable relative to the connector element, thereby to lock the locking element in position. This allows a cable connector to be locked firmly to a mating connector, typically associated with an electrical device, so ensuring the cable connector has the screening (electromagnetic leakage) specification of a push-on connector but the locking specification of a screw connector. The cable connector is sufficiently screened to meet electrical standards whilst ensuring the connector element cannot fall off a mating connector.
Preferably the connector element is a push-on connector ring for securing to a female connector. The locking element may be a locking ring held by the body.
Preferably the body comprises a shaft portion along which the locking element or locking ring is movable, thereby to adjust the locking element position relative to the connector element or push-on connector ring. Typically the body, shaft portion, push-on connector ring and locking ring are all substantially cylindrical. The shaft portion may allow sliding motion of the connector element with the locking element pushed in one direction along the shaft to engage with the connector element and lock it to a mating female connector, and pushed along the shaft in the opposite direction to disengage from the connector element and release the female connector.
The locking element and connector element are preferably provided with interengaging elements capable of locking the locking element and connector element is in a fixed position with respect to each other.
The interengaging elements may be provided in a variety of different ways, and where the connector element is a push-on connector ring and the locking element is a locking ring can be provided by an interengaging channel and protrusion on the respective rings. The channel may be provided by way of an annular groove around an outer surface of the push-on connector ring and the protrusion provided way of a ridge on an inner surface of the locking ring.
The inner surface of the push-on connector ring is preferably provided with a threaded portion thereby to engage with a female connector when in the locked position. The threaded portion preferably extends from an open edge of the push-on connector ring partway along the inner surface and is arranged to only engage with a female connector when the push-on connector ring is locked into position. Thus when introducing a female connector into the aforesaid cable connector, the female o connector is simply pushed into the push-on connector ring initially, with no twisting or screwing movement required, and the threaded portion only engages with the female connector when the locking ring is moved into a locked position.
Preferably the connector element is partially deformable, so as to constrict as the locking element is moved into a locked position, such that in use it is urged against a mating connector, thereby to further secure the mating or female connector in place.
S The invention will now be described, by way of example, and with reference to the accompanying drawings in which: Figure 1 is a cross-section through a cable connector in accordance with the present invention; Figures 2(a) and 2(b) shows the cable connector as it is used to secure a cable to a female connector associated with an electrical device; and Figure 3 shows the cable connector in a fully secured position.
Description
Figure 1 shows a cross-section through a push-on cable connector 10 comprising is cylindrical body 12 associated with cylindrical shaft 14 to which is secured a connector element being push-on connector ring 16. Slideably movable locking element 18 is carried on shaft 14 and disposed between body 12 and connector ring 16. All elements are substantially cylindrical and so generally circular in cross-section, with connector ring 16 nesting within locking ring 18.
The connector ring comprises a hollow cylindrical cap with lid portion 20 formed with a central aperture for receiving shaft 14, and body portion 22 of reduced cross-section compared to portion 22, such that the lid portion 20 extends beyond the circumference of body portion 22. The inner surface of the cylindrical body portion 22 is provided with a threaded portion 24 over part of its surface, with the inner cross-section of body portion 22 gradually tapering such that the circumference decreases along the length of the body portion 22, reaching a minimum at the open mouth of the connector ring. The outer circumference of body portion 22 is constant until near the open mouth furthest from lid 20 where an angled lip 26 extends outwardly, with a 3o circumferential groove 28 provided around the surface of lip 26.
Locking ring 18 is again a hollow cylindrical cap formed with a central aperture in lid for receiving shaft 14. Body 32 of locking ring 18 is of substantially constant internal and external cross-section but the end of the body distal from lid 30 is formed with an inwardly projecting lip 34 with a cylindrical upstanding protrusion or ridge 36.
Figure 1 shows the unlocked position of the connector when it is ready to receive a female connector associated with an electrical device and in the unlocked position, circumferential ridge 36 is spaced from body portion 22 of connector ring 16.
Figures 2(a) and 2(b) show the cable connector as it is used to secure cable 40 to female connector 42. Coaxial cable 40 is secured within body 12, and has a central conductive core 44. Connector ring 16, being of a push-on type, is pushed over the female connector 42 until the female connector 42 is pushed up against shaft 14. No twisting of the female connector is required, merely pushing of the female connector 42 into the connector ring 16.
With the female connector 42 in position, locking ring 18 is deployed as shown in Figure 3 to slide along shaft 14 from the unlocked position shown in Figure 1 to the locked position shown in Figure 3. As locking ring 18 is pushed along shaft 14, ridge 36 remains clear of connector ring 16 until it travels up and over angled lip 26. As ridge 36 travels over angled lip 26, partially deformable ring 16 is urged inwards and its diameter constricted so that threads 24 grip threads of the female connector 42. In the fully locked position, ridge 36 has ridden up and over lip 26 to engage with and sit within channel 28, so locking the push-on connector ring 16 to the female connector 42. To release the female connector 42, the locking ring 18 is simply pushed in the other direction to release the grip of the connector ring 16 and so free the female connector ready for release.
If desired, channel 28 is coloured red such that in the unlocked position the red band is visible and in the locked position, it is not visible. This provides a simple way for users to tell if the connector is locked or not.
By having the locking ring to urge the partially deformable connector ring to grip against the thread of the female connector, the push-on connector ring cannot drop off the female connector. Also the electromagnetic screening of the connector is improved as gaps between the push-on connector and female connector are substantially reduced when in the locked position.
