DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Embodiments of the present invention are described in detail below. It should be understood that the embodiments only illustrate specific ways to implement and use the present invention, and they do not limit the scope of the invention. When describing the structure and spatial relationship of the components, directional terms such as up, down, top, bottom etc. are not absolute, but are relative. The spatial relationship among components may change from those shown in the drawings, and the directional terms used to describe them will change accordingly.

Referring to FIGS. 1 and 2, the self-enclosed electrical assembly with a wire crimping structure may be used in various practical applications, including power outlet socket, ground-fault circuit interrupter (GFCI), electrical switch, light dimmer, etc. FIG. 1 shows the electrical assembly as a part of a switch, and FIG. 2 shows the electrical assembly as a part of a socket. In each of these practical applications, the electrical assembly includes an installation faceplate 1, a front assembly 2 and a back assembly 3 that are fastened to each other using resilient buckles. In different practical applications, the front assembly 2 may be different structure, such as a switch lever in FIG. 1, a socket faceplate in FIG. 2, etc.

The structure and assembly process of a self-enclosed electrical assembly with wire crimping structure according to an embodiment of the present invention are described below with reference to FIGS. 3-8, using the power outlet socket application shown in FIG. 2 as an example.

In this embodiment, the front assembly 2 includes a base plate 200, and an enclosure member 201 which is perpendicular to and extends from the base plate and which has an open top. Disposed inside the enclosure member 201 are plug insertion pieces that have wire receiving slots, including neutral line insertion piece 4, hot line insertion piece 5, and ground line insertion piece 6. As shown in FIGS. 7a, 7b and 8, the neutral line insertion piece 4, hot line insertion piece 5 and ground line insertion piece 6 respectively include neutral wire receiving slots 403, hot wire receiving slots 503, and ground wire receiving slots 603, as well as neutral contact terminal 402, hot contact terminal 502, and ground contact terminal 602 for receiving the respective prongs of a power plug in order to output power. Each wire receiving slot has a U shaped guiding slot at the wire receiving end, such as the neutral wire guiding slots 401, hot wire guiding slots 501, and ground wire guiding slots 601. The U shaped guiding slots can accommodate at least two wires, making it possible to crimp at least two wires at once, simplifying the wire crimping process.

The back assembly 3 includes a top panel 300, and a shell body 310 which is perpendicular to and extends from the top panel 300. Disposed within the shell body 310 is a wire crimping structure, which includes a wire crimping block 308 which spatially corresponds to the wire receiving slots of the insertion pieces of the front assembly 2, and an inserted member. The wire crimping block 308 has multiple wire crimping notches 3081, 3082 and 3083, respectively spatially corresponding to the wire guiding slots or wire receiving slots. The inserted member may be one or more screws 301 (two are shown in the drawings) inserted from the top panel 300 of the back assembly 3. The wire crimping structure further includes a pressing plate 307 which cooperates with the wire crimping block 308, where the screws 301 pass through the washers 305 to contact and press on the pressing plate 307. The pressing plate 307 and the wire crimping block 308 are spatially registered with each other; for example, as shown in FIG. 8, the wire crimping block 308 has positioning posts 3084 and the pressing plate 307 has corresponding positioning holes 3071. When assembling the back assembly 3, the washers 305 are first placed in the back assembly 3; the screws 301 are screwed in, riveted and then withdrawn. The pressing plate 307 is aligned and registered with the wire crimping block 308 via the positioning holes and positioning posts, and they are together inserted into the shell body 310 of the back assembly 3. This completes the assembly of the back assembly 3.

When installing the electrical assembly (socket) at the intended location, as shown in FIG. 7b, two power cables 9 are provided, each cable having three metal wires, each individually covered with an insulator, and an outer cover that enclosed the three insulated metal wires. The outer PVC cover for a segment of each cable is stripped to expose the three insulated metal wires. The insulating layer of the wires are not removed at this time. The insulated wires may be shaped as desired if necessary. The two neutral wires and two hot wires of the two cables are respectively fitted into the neutral wire guiding slots 401 of the neutral line insertion piece 4 and the hot wire guiding slots 501 of the hot line insertion piece 5, and the two ground wires are fitted into the ground wire guiding slots 601 of the ground line insertion piece 6. Then, the back assembly 3 and the front assembly 2 are affixed to each other via buckles. The screws 301 are screwed into the back assembly 3 using an electric screw driver, so that the wire crimping notches of the wire crimping block 308 press the wires into the corresponding wire receiving slots. When the wires are pressed into the wire receiving slots, the wire receiving slots puncture the insulating layers of the wires and tightly clamp the wires. This completes the wiring of the self-enclosed power outlet socket.

The wire crimping structure additionally includes at least one spring 306 (two are shown in the drawings) disposed between the top panel 300 and the pressing plate 307 of the back assembly 3. As shown in FIGS. 4 and 5, the springs 306 are in their natural state when the screws 301 are not yet screwed in and the pressing plate 307 and the wire crimping block 308 are in the un-pressed position. After the screws 301 are screwed in, under the force of the screws, the springs 306 are stretched, and the pressing plate 307 and wire crimping block 308 move downwards to press the wires into the wire receiving slots. While in the illustrated embodiment the two springs 306 are respectively affixed to the positioning posts 3084, in other embodiments, they may be affixed to the screws 301, for example they may be respectively disposed around the screws.

After the wiring step is completed, the front assembly 2 and the faceplate 1 are assembled together in a screw-less manner using buckles. To achieve this, the faceplate 1 is provided with multiple resilient cone shaped buckles 101 (four are shown in FIG. 8). Correspondingly, the base plate 200 of the front assembly 2 is provided with multiple buckle receivers 204. When assembling the faceplate 1 and the front assembly 2, the multiple cone shaped buckles 101 are respectively aligned with and inserted into the multiple buckle receivers 204. Because the mid-section of each cone shaped buckle 101 is slanted so that buckle is wider toward the top, the cone shaped buckle 101 becomes stuck in the buckle receiver 204, which achieves spring-loaded mounting of the faceplate 1 with the front assembly 2. FIG. 8 also shows that the faceplate 1 is provided with a pry slot 102 on at least one side, which allows a tool to be inserted to separate the faceplate 1 and the front assembly 2 by prying. Because the cone shaped buckles 101 are resilient, with a sufficient prying force, they will slide out of the buckle receivers 204, allowing the faceplate 1 and the front assembly 2 to separate.

As mentioned earlier, the back assembly 3 and the front assembly 2 are affixed to each other by buckles. To achieve this, the side walls of the enclosure member 201 of the front assembly 2 are provided with multiple resilient hooks, and the side walls of the shell body 310 of the back assembly 3 are provided with multiple hook receiving structures. Alternatively, hooks may be provided on the shell body 310 and hook receiving structures may be provided on the enclosure member 201, or opposing hooks may be provided on the shell body 310 and the enclosure member 201, etc. In a preferred embodiment, of the multiple hooks and hook receiving structures, the ones located near the two ends of the side wall have a smaller amount of engagement between the hook and the hook receiving structure as compared to the ones located near the center of the side wall. As shown in FIG. 8, the side wall of the front assembly 2 is provided with three hooks (there are three other hooks on the opposite side wall, not visible in FIG. 8), including a larger hook 202 near the center of the side wall and two smaller hooks 203 near the two ends of the side wall. Correspondingly, the side wall of the back assembly 3 is provided with three hook receiving structure s (there are three other ones on the opposite side wall, not visible in FIG. 8), including a larger hook receiving structure 303 near the center of the side wall and two smaller hook receiving structures 304 near the two ends of the side wall. Using three sets (and three more sets on the opposite side wall) of hooks and hook receiving structures, the front assembly 2 and the back assembly 3 can be securely fastened to each other. In addition, when the front assembly 2 and the back assembly 3 need to be separated, such as to replace the socket or to add or change wires, the above-described structure is easier to operate than conventional devices. Conventional devices typically have multiple hooks and hook receiving structures that are independent of each other; when one hook is pried to disengage from its hook receiving structure, the other hooks are still engaged with their hook receiving structures, making it hard to separate the two pieces. In the embodiment of the present invention, the three hooks or the three hook receiving structures are formed integrally; when separating the two pieces, one only needs to pry from an end of the side wall toward the center, and because the amount of engagement of the hook is smaller for the hooks near the end, less amount of prying is required so it is relatively easy to pry the back assembly 3 off from the front assembly 2.

In one embodiment, the electrical assembly additionally includes at least one install stop. As shown in FIG. 8, two install stops 8 are provided near the two opposing side walls of the front assembly 2. Each install stop 8 includes a screw hole 801 and an arm 802, where the screw hole 801 receives an install screw 7. On the corresponding side walls of the shell body 310 of the back assembly 3, corresponding wings 309 are provided. After the wiring of the self-enclosed socket is completed, the socket is placed in the hollow space of the wall, and the install screw 7 is screwed in using an electric screw driver. The install stop 8 rotates in a clockwise direction due to the rotation of the install screw 7, until it contacts the wing 309 of the back assembly 3, where the install stop 8 stops and presses the wing 309. When the install screw 7 continues to be screwed in, the install stop 8 causes the front assembly 2 and the back assembly 3 to be tightly affixed to each other. This completes the installation of the electrical device.

As shown in FIGS. 3, 6 and 8, the front assembly 2 further includes at least one blocking plate 205 which extends outwardly from the side wall of the enclosure member 201 adjacent the install stop, in a substantially perpendicular direction with respect to the side wall. Two blocking plates 205 on opposite side walls are shown in the Figures. The blocking plates 205 can block the arm 802 of the corresponding install stop 8 to prevent it from rotating too far, e.g. beyond a defined range, in a counter-clockwise direction.

The self-enclosed electrical assembly with a wire crimping structure according to embodiments of the present invention can achieve the result that during installation, after the front assembly and back assembly are affixed to each other by the buckles, the wire crimping structure can simultaneously crimp multiple wires into the wire receiving slots. This process is reliable and greatly saves the time and cost related to the wire crimping steps. The electrical assembly according to embodiments of the present invention is easy to install and uninstall, and is suitable for a variety of practical applications.

It will be apparent to those skilled in the art that various modification and variations can be made in the electrical assembly and related method of the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover modifications and variations that come within the scope of the appended claims and their equivalents.
