As shown in fig. 1-3, the interlocking connector 100 includes a housing 110, two movable protrusion members 120a, 120b, a spring 130, an actuator 140, a cover member 150, and a screw 160. The housing 110 has a generally cylindrical body 112, the body 112 having a central axis x. The housing 110 also has insert plates 114a, 114b arranged on both sides of the cylindrical main body 112, substantially parallel to the central axis x. As shown, the insert plates 114a, 114b are substantially parallel to the central axis x, and have a thickness that tapers from one end to the other in the axial direction. The housing 110 defines an interior space and includes two slots 116a, 116b and an opening, the slots 116a, 116b extending through the respective insert plates 114a, 114b generally radially of the main body 112 and communicating with the interior space of the housing 110, the opening of the housing being disposed at an axial end of the main body 112 and communicating with the interior space of the housing 110. As best shown in fig. 2, the movable protrusions 120a, 120b, the spring 130, and the actuator 140 are accommodated in the inner space of the main body 112. The movable protrusions 120a, 120b extend generally in a radial direction of the main body 112 and are arranged to be movable in the radial direction within the housing 110. The movable tabs 120a, 120b are aligned with the two notches 116a, 116b, respectively, and are extendable from the respective notches 116a, 116b under the action of the spring 130, and retractable from the respective notches 116a, 116b under the action of the actuator 140. As shown in fig. 2, the radially inner ends of the movable protrusions 120a, 130b engage the spring 130 to protrude from the respective notches 116a, 116b under the elastic force of the spring 140. The movable projections 120a, 120b are also formed with generally axially extending posts 122a, 122b adjacent their radially inner ends, the posts 122a, 122b extending into the actuator 140 for interaction therewith, the posts 122a, 122b having collars 124a, 124b respectively fitted thereon which are rotatable relative to the posts 122a, 122 b. The radially outer ends of the movable protrusions 120a, 120b are formed with slopes 126a, 126b, respectively. The actuator 140 has a cylindrical body 142 to be rotatable in the inner space of the housing 110. One axial end of the actuator 140 is provided with an actuating portion to engage with the posts 122a, 122b of the movable protrusion members 120a, 120b (the specific operation is described below). The other axial end of the actuator 140 includes a handle portion 146 that projects axially from an opening in the housing 110. The interlocking connector 100 also includes a cap 150 and a screw 160. Screws 160 secure the cover 150 to the open end of the housing 110 through corresponding holes 154 in the cover 150 to confine the actuator 140, etc., within the interior space of the housing 110.
Fig. 4A and 4B are cross-sectional views illustrating the interaction between the actuator 140 and the movable protrusions 120a, 120B. As shown, the actuation portion of the actuator 140 includes actuation surfaces 144a, 144 b. The actuating surfaces 144a, 144b extend substantially in a circumferential direction with respect to the centre axis, with a gradually increasing distance from the centre axis x from one end to the other end thereof. In the position shown in fig. 4B, the movable projections 120a, 120B are in a radially outward position under the spring force of the spring 130 therebetween, such that their radially outer ends protrude from the notches 116a, 116B. Upon rotation of the actuator 140 about the central axis in a counterclockwise direction in fig. 4B, the posts 122a, 122B of the movable tabs 120a, 120B (and the collars 124A, 124B) move against the actuation surfaces 124A, 124B such that the actuation surfaces 124A, 124B move the movable tabs 120a, 120B in a radially inward direction such that the movable tabs 120a, 120B retract from the slots 116a, 116B, as shown in fig. 4A.
Fig. 5A-5D illustrate the process of connecting the interlocking connector 100 with the light fixture 200, where fig. 5A-5C illustrate the internal operation of the interlocking connector 100 during the connection process. As shown in fig. 5D, the light fixture 200 includes four connection portions 210 evenly spaced around its perimeter, the connection portions including slots adapted to receive the insert plates 114a, 114b of the interlocking connector 100, and apertures 212 in the slots. The operation of connecting the interlocking connector 100 with the light fixture 200 is very simple, simply by inserting the insert plate of the interlocking connector 100 into the slot of the corresponding connecting portion 210 of the light fixture 200. Fig. 5A shows the state of the interlocking connector 100 before being inserted into the slot of the connection portion 210 of the light fixture 200. After the card board of the interlocking connector 100 is inserted into the socket, the socket bottom surface presses against the inclined surfaces 126a, 126B of the movable protrusion pieces 120a, 120B, causing the movable protrusion pieces 120a, 120B to retract from the notches 116a, 116B in the direction indicated by the arrows in fig. 5B. As the insert plate of the interlocking connector 100 is further inserted into the socket, the movable tab members 120a, 120b are moved into alignment with the apertures 212 in the socket, at which point the movable tab members 120a, 120b project from the respective notches 116a, 116b into the apertures 212 due to the spring force of the spring 130, thereby securing the interlocking connector 100 and the light fixture 200 in position relative to each other.
Fig. 6A-6D illustrate the process of removing the interlocking connector 100 from the light fixture 200. Fig. 6A shows the interior of the interlocking connector 100 when the interlocking connector 100 and the light fixture 200 are connected together, with the insert plate of the interlocking connector 100 inserted into the slot of the light fixture 200 and the movable tab members 120a, 120b protruding from the respective notches 116A, 116b into the aperture 212. Next, as shown in fig. 6B, the handle portion 146 of the actuator 140 is rotated 90 degrees counterclockwise, causing the movable tabs 120a, 120B to retract from the slots 116a, 116B by interaction between the actuating surfaces 124a, 124B of the actuator 140 and the posts 122a, 122B of the movable tabs 120a, 120B (and the collars 124a, 124B), as shown in fig. 6B. At this point, the interlocking connector 100 may be removed from the light fixture 200 in the direction indicated by the arrow in fig. 6D, since the movable tabs 120a, 120b have been retracted from the notches 116a, 116b (and the aperture 212). After the insert plates of the interlocking connector 100 are withdrawn from the slots of the light fixture 200, the radially outer ends of the movable protrusion members 120a, 120b are caused to protrude from the notches 116a, 116b by the elastic force of the springs 130, as shown in fig. 6C.
As described above, the connection and the disconnection between the interlocking connector 100 and the lighting fixture 200 are very simple, wherein the firm connection between the interlocking connector 100 and the lighting fixture 200 can be achieved only by inserting the insert plate of the interlocking connector 100 into the slot of the lighting fixture 200. In addition, during the connection process, when the movable protrusion pieces 120a, 120b of the interlocking connector 100 enter the opening 212 under the elastic force of the spring 130, the user can hear a sound such as a click, thereby clearly knowing that the interlocking connector 100 and the lighting fixture 200 have been interlocked together. When detaching the interlocking connector 100 from the lighting fixture 200, it is only necessary to rotate the handle portion 146 of the actuator 140 of the interlocking connector 100 by 90 degrees counterclockwise and then pull out the interlocking connector 100 from the socket of the lighting fixture 200. In addition, the interlocking connector 100 has a simple structure, includes a small number of components, and is low in manufacturing cost.
