Description
Technical Field
The present invention relates to an electrical connector for a lighting device and a lighting device including the same.
Background
For a lighting device commonly used at present, such as a tube type lighting device having a light engine of a conventional light source, the light engine needs to be electrically connected to a power supply through a connector device and a fixation of a position and a lighting direction of the light engine is achieved. However, the illumination direction of the light engine cannot be adjusted after the known connector device is connected to the light engine, i.e. the connection between the light engine and the connector device is mechanically fixed and cannot be changed, for example, the light engine cannot be rotated relative to the connector device, so that the illumination direction of the light engine can be changed.
In addition, according to other types of connector devices known at present, a user must detach the connector device from the light engine, i.e., separate the connector device from the light engine, to adjust the illumination direction of the light engine, and then re-connect the light engine and the connector device after the adjustment is completed. The above design of the connector device is very disadvantageous for flexible use of the lighting device, and the user cannot flexibly and conveniently adjust the lighting direction and lighting angle of the light engine to adapt the lighting of the lighting device to a specific application environment. The design of such lighting devices inevitably limits the applicable places for the lighting device and the user has to find a lamp holder matching the light engine to ensure that the light is shining in the correct direction, which is also unfriendly for the user.
Disclosure of Invention
In order to solve the technical problems described above, the present invention provides a novel electrical connector for a lighting device and a lighting device including the same. With the lighting device using the electrical connector according to the present invention, the lighting direction and lighting angle of the lighting device can be adjusted without removing the electrical connector. In addition, the electrical connection structure according to the present invention is simple, easy to manufacture and assemble, convenient for a user to actually operate, and has good user-friendliness.
The first object of the present invention is achieved by an electrical connector comprising a first member and a second member mounted on the first member, characterized in that the electrical connector further comprises a first locking structure, wherein the first locking structure comprises a first sub-structure provided on the first member and a second sub-structure provided on the second member, wherein the first member and the second member are locked to each other in a first position and the first member and the second member are separated by a predetermined distance in a second position in which the locking of the first sub-structure and the second sub-structure is released, thereby enabling the first member and the second member to rotate relative to each other.
The electrical connector according to the invention is designed to comprise two parts which are locked to each other in the locked state, i.e. in the first position, but which, after separating the two parts by a predetermined distance, are preferably moved axially one of the parts away from the other part, the two parts then enter the second position, so that the locking of the two parts is released, i.e. one of the parts can be rotated relative to the other part. Furthermore, according to one embodiment of the invention, one of the two parts can be rotated continuously relative to the other part and, after an angle of rotation, locked again by bringing the two parts closer to one another again.
The electrical connector according to the invention is further preferably designed such that the first substructure can be moved out of the second substructure when the second part is moved from the first position into the second position and the first substructure can be moved into the second substructure again when the second part is moved back from the second position into the first position. This provides a reusable electrical connector in which a user can adjust the angle of rotation between the first and second members at will according to the particular needs of use, and always return the first and second members to the locked state after the adjustment is completed.
According to a preferred embodiment of the invention, the first substructure can be brought into contact with the second substructure in the first position in a form-fitting manner. The first sub-structure may have a specific shape as required by the process of manufacture and the second sub-structure may in turn have a structure matching the first sub-structure such that the first sub-structure is able to lock the first and second parts of the electrical connector when it is received at least partially in the second sub-structure by entering the second sub-structure.
Preferably, the second sub-structure is circumferentially arranged on the inner surface of the sidewall of the second part. The provision of the locking structure particularly inside the first and second components avoids the locking structure being visible from the outside of the electrical connector, thereby providing a good appearance. Furthermore, the second substructure provided on the inner surface of the side wall of the second part is capable of interacting with the first substructure provided on the first part and facing the side wall of the second part.
Preferably, the first substructure is designed as a projection and the second substructure as a recess, or the first substructure is designed as a recess and the second substructure as a projection. Thus, in the locked state, the first substructure can enter the second substructure and be at least partially accommodated therein, or the second substructure can enter the first substructure and be at least partially accommodated therein.
Preferably, the grooves are uniformly arranged on the inner surface of the side wall. In the case where the grooves are uniformly distributed on the inner surface of the side wall, the first member can be smoothly locked with the second member again after the first member is continuously rotated by any angle or a predetermined angle with respect to the second member.
The electrical connector according to the invention is further preferably designed in that the second component further comprises a second locking structure, wherein the second locking structure is capable of defining a predetermined distance separating the first component and the second component. The second locking structure can prevent the first component from completely disengaging from the second component during separation of the first component from the second component. In other words, the travel of the first partial structure on the first component relative to the second partial structure on the second component is defined according to the distance that the first component and the second component are separated from each other and is allowed by the second locking structure.
Preferably, the second part comprises a cover, wherein the second locking formation extends from the plane of the cover and is connected to the first part after the second part has been mounted on the first part. The second locking structure can thus be made integral with the cover of the second component, which facilitates assembly and subsequent operation of the electrical connector.
It is further preferred that the second locking structure is arranged coaxially with the first and second parts. The first member and the second member may each have a cylindrical shape, and the second locking structure may be provided at a central region of the second member, so that the second locking structure can be simultaneously aligned and coupled with the second member after the first member is mounted on the second member, and when the first member or the second member is rotated, the second locking structure does not interfere with the rotation but coaxially rotates with the second member with respect to the first member.
Another object of the invention is achieved by a lighting device comprising an electrical connector according to the above. The lighting device according to the present invention has the electrical connector designed according to the present invention, which is simple in structure, easy to manufacture and assemble, and enables a user to conveniently adjust the lighting direction and angle of the lighting device.

Detailed Description
Fig. 1 shows an exploded schematic view of an electrical connector 100 according to the present invention. An electrical connector 100 according to the present invention comprises a first member 1 and a second member 2, wherein the second member 2 is rotatably mounted on the first member 1. In particular, the second component 2 can be mounted on the first component 1 about a rotational axis. When the first and second parts 1, 2 are locked, the second part 2 cannot rotate relative to the first part 1. However, after separating the first member 1 from the second member 2, the second member 2 can be rotated relative to the first member 1, and after re-coupling the second member 2 to the first member 1, the first member 1 and the second member 2 are locked again.
Fig. 2 shows a partially enlarged view of the first member 1 of the electrical connector 100 according to the present invention. The first member 1 of the electric connector 100 according to the present invention has the boss 11 protruded from the bottom, and the extension 12 is extended from the edge of the boss 11, however, the extension 12 is not directly contacted with the second member 2 when the first member 1 is connected with the second member 2. A projection is provided on the extension 12, which projection serves as a first substructure 31 of the first locking structure 3. The first substructure 31 is able to directly contact a second substructure 32 arranged on the second component 2 when the first component 1 is connected to the second component 2 to form a locking of the first component 1 and the second component 2. The protrusion as the first substructure 31 is formed to be stationary with respect to the first component 1, i.e. the protrusion does not move with respect to the first component 1 when the second component 2 or the first component 1 is rotated. Furthermore, two or more projections may be provided, wherein in the case of two projections, for example, the projections may be arranged symmetrically with respect to the axis of rotation.
Fig. 3 shows a partially enlarged view of the second part 2 of the electrical connector 100 according to the invention. The second part 2 of the electrical connector 100 according to the present invention has grooves which in the present embodiment may preferably be designed to be evenly distributed in the circumferential direction on the inner surface of the side wall of the second part 2. This recess acts as a second substructure 32 of the first locking structure 3, which interacts with the first substructure 31. Furthermore, the recesses can also preferably be designed to be spaced apart from one another, or at different distances from one another. When the first member 1 and the second member 2 of the electric connector 100 are connected, the projection on the first member 1 enters the groove on the second member 2. The recess is designed in particular to have a shape matching the projection, i.e. for example the projection can be designed to have a circular cross section as shown in the figures, and the recess can accordingly have a circular cross section, or the projection can be designed to have a polygonal cross section, not shown, and the recess can accordingly have a polygonal cross section. The shape of the projections and the grooves may be selected as the actual case may be, in the case of facilitating the manufacture of the electrical connector 100.
Fig. 4 shows a side view of the first locking structure 3 of the electrical connector 100 according to the present invention. Fig. 4 shows an exemplary side view of the projection on the first component 1 when it is removed from the recess on the second component 2. After separating the first part 1 from the second part 2 by a predetermined distance, the protrusion can be removed from the recess, i.e. from a state in which the protrusion is at least partly received in the recess to a state in which the protrusion is not received in the recess. In this case, the first 31 and second 32 sub-structures are unlocked, and the first part 1 can then become rotatable relative to the second part 2 around the rotation axis, for example to rotate the light engine of the lighting device, thereby adjusting the lighting direction of the lighting device.
Fig. 5 shows a cross-sectional view of the second locking structure 4 of the electrical connector 100 according to the present invention in the first position. After the first component 1 of the electrical connector 100 is mounted on the second component 2, the projection on the first component 1 as the first substructure 31 is at least partially received in the recess on the second component 2 as the second substructure 32, whereby the first component 1 and the second component 2 are locked. In this case, the second locking structure 4 extending from the cover 5 of the second part 2 extends into the second part 2 but is not locked with the second part 2, i.e. the second locking structure 4 in this case allows the second part 2 to be separated from the first part 1, i.e. the second part 2 can be moved away from the first part 1 in the direction of the axis of rotation, but the distance of separation of the second part 2 from the first part 1 is limited by the depth of the second locking structure 4 into the second part 2.
Fig. 6 shows a cross-sectional view of the second locking structure 4 of the electrical connector 100 according to the present invention in the second position. In contrast to the situation shown in fig. 5, in fig. 6, after separating the first component 1 from the second component 2 by a predetermined distance, the barbs of the second detent structures 4 catch on the second component 2, so that the second component 2 can no longer be separated from the first component 1. Nevertheless, the travel of the second component 2 defined by the second latch structure 4 allows the projection on the second component 2 to move sufficiently out of the recess on the first component 1 to unlock the first and second components 1, 2.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
