The conductive terminal 220 further includes a third portion connecting the first portion 221 and the second portion 222, and the third portion is clamped inside the main body 210, so that the conductive terminal 220 is fixedly installed on the main body. The power supply component 412 has an insertion port. During the connector piece 200 is inserted toward the power supply component 412, the first portion 221 is inserted into and connected with the insertion port of the power supply component 412, so that the electrical connection between the connector piece 200 and the power supply component 412 is realized.

The total number of the buckles 211 may be more than three and the total number of the stuck notches 1162 may be more than three.
The light source module 410 described above further includes a light distribution element 413. The light distribution element 413 includes an accommodation portion 413a and an optical portion 413b, the accommodation portion 413a is configured to accommodate the power supply component 412 and a portion of the connector piece 200, and the optical portion 413b is configured to accommodate the light source component 411 and cover the plurality of light emitting units 411b of the light source component 411 to distribute light from the plurality of light emitting units 411b. The light source component 411, the power supply component 412, and the connector piece 200 are quickly assembled and connected by the light distribution element 413.
As shown in
As a modification example, the optical portion 413b and the accommodation portion 413a are respectively disposed at two ends of the light distribution element 413. In this case, the light source component 411 and the power source component 412 are correspondingly arranged at two ends of the light source module, and the connector piece 200 is arranged on the power supply component 412.
The light distribution element 413 further includes a connection portion 413c connecting the accommodation portion 413a and the optical portion 413b, and at least two connection portions 413c divide the accommodation region into at least two separated spaces. The connection portions 413c divide the accommodation region into several separated spaces, which is related to the structures of the accommodation portion 413a and the optical portion 413b. If the accommodation portion 413a (in other words, the power supply component and the connector seat) is arranged in the middle region, and the optical portion 413b (in other words, the light source component) surrounds the accommodation portion 413a and is not directly in contact with the accommodation portion 413a, at least two connection portions 413c divide the accommodation region into at least two separated spaces. For example, two connection portions 413c divide the accommodation region into two separated spaces, and three connection portions 413c divide the accommodation region into three separated spaces. If the accommodation portion 413a is provided at a position deviating the middle region of the accommodation region surrounded by the optical portion 413b and an end of the accommodation portion 413a is in direct contact with the optical portion 413b, the accommodation region is divided into at least three separated spaces by at least two connection portions 413c. For example, two connection portions 413c divide the accommodation region into three separated spaces, and three connection portions 413c divide the accommodation region into four separated spaces.
Referring to
A side of the optical portion 413b facing the light source component 411 has a recess that accommodates the light source component 411 (
The light distribution element 413 has two opposite surfaces, i.e. a first surface and a second surface. Herein, the first surface faces the light source component 411, the connector piece 200, and the power supply component 412, and the second surface is a light emitting surface. The accommodation groove, the recess, and the wire slot, which are described above, are all arranged on the first surface.
In the case that the accommodation portion 413a of the light distribution element 413 is not in direct contact with the optical portion 413b of the light distribution element 413, the power supply substrate and the light source substrate 411a are separately arranged, and the power supply substrate and the light source substrate 411a are connected with each other by a wire, and the wire is arranged in the wire slot of the connection portion 413c. In the case that the accommodation portion 413a of the light distribution element 413 is in direct contact with the optical portion 413b of the light distribution element 413, the power supply substrate and the light source substrate 411a may be arranged integrally or separately. If the power supply substrate and the light source substrate 411a are arranged separately, the power supply substrate and the light source substrate 411a are electrically connected with each other by a wire or an electrical connector, and the electrical connector is arranged at the junction of the accommodation portion 413a and the optical portion 413b.
The light source module 410 further include a cover plate (not shown), which cooperates with the optical portion 413b to seal the recess, thereby sealing the light source component inside the optical portion 413b. The cover plate may further seal the wire slot of the connection portion 413c to protect the wire provided in the wire slot.
The light source component 411 may be installed and fixed on the light distribution element 413 by the cover plate, or be connected with the light distribution element 413 in a screwed manner, or may be installed on and connected with the light distribution element 413 in a buckling manner. As shown in
The light source substrate 411a of the light source component may have a circular ring shape, a square ring shape, or any other approximate ring shape. The light source substrate 411a may have a closed circular ring shape, a closed square ring shape, or any other approximate closed ring shape, or may have a circular shape having an opening, a square ring shape having an opening, or other approximate ring shape having an opening. Correspondingly, the shape of the optical portion 413b of the light distribution element may be changed accordingly. The orthographic projection of the accommodation portion 413a of the light distribution element on the base may be a circular shape, a square shape, a rectangular shape, or any other irregular shape. In the case that the light source substrate 411a and the power supply substrate are integrally formed, the integrated substrate of the two substrates may have a circular shape, a triangular shape, a rectangular shape, a polygonal shape, or other irregular shape.
The light source module 410 in the illumination device 100 and the connector piece installed on the light source module 410 have been described above. The base 420 in the illumination device and the connector seat 100 installed on the base 420 will be described in detail below.
As shown in
The connector seat 100 is configured to connect the connector piece 200 and the wire that correspond to the connector seat 100, so that the wire 430 and the connector piece 200 are electrically connected with each other.
Referring to
The wire connection portion 120 includes a first conductive sheet 123, a first elastic member 121, and a control key 122. The first elastic member 121 applies elastic force toward the first conductive sheet 123 to press the wire tightly onto the first conductive sheet 123. The control key 122 drives the first elastic member 121 to move away from the first conductive sheet 123 to reduce the pressing force of the first elastic member 121 on the wire, thereby facilitating the separation of the wire 430 from the connector seat 100. During the wire 430 is connected with the connector seat 100, the elastic force that is generated upon the wire resisting against the first elastic member 121 is directly introduced between the first conductive sheet 123 and the first elastic member 121, and the wire is pressed tightly onto the first conductive sheet 123 by the first elastic member 121 to realize quick electrical connection of the connector seat 100 and the wire. In the case that the wire needs to be detached from the connector seat, the first elastic member 121 is driven to move away from the first conductive sheet 123 by the control key 122, so that the pressing force exerted on the wire is reduced, and the connector seat 100 is quickly separated from the wire.
The first elastic member 121 is provided such that the plane where the first elastic member 121 is located intersects the middle portion of the first conductive sheet 123, which ensures that the wire can still be pressed tightly onto the first conductive sheet 123 even when the first elastic member 121 is displaced. The first elastic member 121 may abut against and connect with the middle portion of the first conductive sheet 123, or may maintain a gap with the middle portion of the first conductive sheet 123. The gap should be smaller than the diameter of the wire so that the wire can be pressed tightly onto the first conductive sheet 123.
As a modification example, the plane where the first elastic member 121 is located may intersect two ends of the first conductive sheet 123 other than the middle portion.
The first elastic member 121 includes a pressing edge adjacent to the first conductive sheet 123 for abutting against and connecting with the wire, the pressing edge is parallel to the first conductive sheet 123, and the distance between the pressing edge and the first conductive sheet 123 is smaller than the diameter of the wire.
The first elastic member 121 is inclined with respect to the first conductive sheet 123, and the wire passes between the first elastic member 121 and the first conductive sheet 123 at an acute angle between the first elastic member 121 and the first conductive sheet 123. In other words, the first elastic member 121 is set as a first half plane, and the first conductive sheet 123 has a second half plane and a third half plane separated by the first half plane. Herein, the angle between the first half plane and the second half plane is A, the angle between the first half plane and the third half plane is B, and the sum of A and B is 180 degrees. If A is an acute angle, the wire passes between the first elastic member 121 and the first conductive sheet 123 at A. If B is an acute angle, the wire passes between the first elastic member 121 and the first conductive sheet 123 at B. The wire passes between the first elastic member 121 and the first conductive sheet 123 at the acute angle, so that the wire can conveniently pass with resisting a small elastic force.
In practical application, the first elastic member 121 with a sheet shape may be perpendicular to the first conductive sheet 123.
It should be noted that the connector seat 100 further includes a first installation portion 1211 integrally formed with the first elastic member 121. The first installation portion 1211 is fixedly installed in the electrical cavity 111, and the first installation portion 1211 has a bendable flat plate shape. The first elastic member 121 is close to the first conductive sheet 123, while the first installation portion 1211 is away from the first conductive sheet 123. The first installation portion 1211 and the first elastic member 121 form a V-shape, and the included angle between the first installation portion 1211 and the first elastic member 121 is an acute angle, so that the first elastic member 121 has a large elastic force and can be reset when the external force disappears.
The base body 110 of the connector seat 100 has an annular shape, and the side wall of the base body 110 surrounds the electrical cavity 111. The side wall of the base body has a wire passing hole 113 through which the wire passes from an outer side of the connector seat into the electrical cavity 111. The opening of the acute angle formed by the first elastic member 121 and the first conductive sheet 123 faces the wire passing hole 113, and the axial direction of the wire passing hole 113 is parallel to the first conductive sheet 123.
In the examples of the present disclosure, the electrical cavity 111 has two wire connection portions 120 which are symmetrically arranged, and the base body 110 has two wire passing holes 113, so that two wires 430 respectively penetrate into the electrical cavity 111 through the wire passing holes 113 and are respectively connected with the corresponding wire connection portions 120.
The electrical cavity 111 has an opening 1114 and a bottom wall, herein the bottom wall is arranged opposite to the opening 1114. The first elastic member 121 and the first conductive sheet 123 are arranged on the bottom wall. A control key installation portion configured to install the control key 122 is arranged on the bottom wall. The control key 122 is installed on the control key installation portion in a reciprocally slidable manner, and the control key 122 drives the first elastic member 121 to approach to or depart from the first conductive sheet 123 by reciprocally sliding at the bottom wall.
In the examples of the present disclosure, the control key 122 is arranged in parallel with the first conductive sheet 123 and opposite to the first elastic member 121. If the control key 122 slides toward the first elastic member 121, the first elastic member 121 is pressed away from the first conductive sheet 123, so that the pressing force applied by the first elastic member 121 on the wire or the first conductive sheet 123 is reduced. If the control key 122 slides away from the first elastic member 121, the pressed first elastic member 121 is reset, and the pressing force applied by the first elastic member 121 on the wire or the first conductive sheet 123 increases again.
As a modification example, the control key 122 is directly connected with the first elastic member 121 to control the distance between the first elastic member 121 and the first conductive sheet 123. For example, the control key 122 is arranged at a side of the first elastic member 121 close to the first installation portion 1211, the first elastic member 121 is pulled toward the first installation portion 1211 when the control key 122 slides toward the first installation portion 1211, and the pressing force applied by the first elastic member 121 on the wire or the first conductive sheet 123 is reduced. When the control key 122 slides toward the first conductive sheet 123, the first elastic member 121 is pushed toward the first conductive sheet 123, and the pressing force applied by the first elastic member 121 on the wire or the first conductive sheet 123 increases.
The control key installation portion includes a sliding platform 1111 and a drive hole 1112 adjacent to each other, the sliding platform 1111 is disposed on the inner surface of the bottom wall, and the drive hole 1112 penetrates through the bottom wall. Correspondingly, the control key 122 has an L shape and includes a push portion 1221 and a drive portion 1222 which are perpendicular to each other. The push portion 1221 is installed on the sliding platform 1111, and is configured to be in contact with the first elastic member 121 and move along the extension direction of the sliding platform 1111. The drive portion 1222 penetrates through the drive hole 1112 and reciprocally moves in the radial direction in the driving hole 1112 under the action of an external force. The drive hole 1112 can not only allow the drive portion 1222 to slide therein, but also limit the sliding distance of the control key 122.
Herein, the extension direction of the sliding platform 1111 is perpendicular to the plane where the first conductive sheet 123 is located, so that the distance between the first elastic member 121 and the first conductive sheet 123 can be controlled with the shortest sliding distance.
In a direction from the inner surface of the bottom wall to the outer surface of the bottom wall, the drive portion 1222 has a wedge shape narrowing gradually in the drive hole 1112, that is, the width of the drive portion 1222 gradually decreases in the drive hole 1112, so as to facilitate an external force applying object to extend into the drive hole 1112 from the outer surface of the bottom wall to apply the drive force to the drive portion 1222. In the examples of the present disclosure, the bottom wall is located directly below the electrical cavity, the drive portion 1222 has an inverted quadrangular pyramid shape.
The electrical cavity 111 further includes a terminal connection portion 130 corresponding to the wire connection portion 120, and the terminal connection portion 130 is connected with the conductive terminal of the connector piece. The terminal connection portion 130 includes a second conductive sheet 132, a second elastic member 131, and an arc-shaped hole 1113. The second conductive sheet 132 is electrically connected with the first conductive sheet 123, thereby realizing the electrical connection of the wire connection portion 120 with the terminal connection portion 130, and the second conductive sheet 132 and the first conductive sheet 123 may be integrally formed. The second elastic member 131 may apply pressure to the second conductive sheet 132 to press the second conductive sheet 132 tightly onto the conductive terminal 220 to realize the electrical connection between the conductive terminal 220 and the second conductive sheet 132. The arc-shaped hole 1113 is provided in the bottom wall of the electrical cavity 111 for the conductive terminal 220 to be in a rotatable connection with the second conductive sheet 132 after being inserted into the electrical cavity 111.
The second elastic member 131 may be a coil spring, one end of which is fixedly connected in the electrical cavity 111, and the other end of which is connected to the first surface of the second conductive sheet 132. The second elastic member 131 may apply a force that directs toward the arc-shaped hole 1113 onto the second conductive sheet 132. The conductive terminal 220 abuts against and connects with the second surface of the second conductive sheet 132, and the second surface is opposite to the first surface.
The opening of the central angel of the projection of the arc-shaped hole 1113 in the direction perpendicular to the arc-shaped hole 1113 faces the second conductive sheet 132, and the projection of the second conductive sheet 132 in the direction perpendicular to the arc-shaped hole 1113 has an arch shape, and the arch shape protrudes toward the arc-shaped hole 1113. Therefore, the projection of the central arc segment of the arc-shaped hole 1113 may be partially overlapped with the projection of the second conductive sheet 132. The conductive terminal 220 is inserted into the electrical cavity 111 from one of the two ends of the arc-shaped hole 1113 and rotates toward the central arc segment of the arc-shaped hole 1113. During the rotating of the conductive terminal 220, the second conductive sheet 132 and the second elastic member 131 are pressed, so that the conductive terminal 220 is effectively connected with the second conductive sheet 132.
If the projection of the central arc segment of the arc-shaped hole 1113 in the direction perpendicular to the arc-shaped hole 1113 does not overlap with the projection of the second conductive sheet 132, it may be configured such that the opening size of the two ends of the arc-shaped hole 1113 is larger and the opening size of the central arc segment is smaller, and the conductive terminal 220 of the connector piece may be configured such that the diameter of the end portion of the conductive terminal 220 is larger and the diameter of the root portion of the conductive terminal 220 is smaller. The conductive terminal 220 is inserted into the electrical cavity from one of the two ends of the arc-shaped hole 1113. The conductive terminal 220 is rotated to the arc segment in the middle portion of the arc-shaped hole 1113, the root portion of the conductive terminal 220 is stuck in the arc-shaped hole 1113, and the end portion of the conductive terminal 220 is effectively connected with the second conductive sheet 132.
The first conductive sheet 123 and the second conductive sheet 132 are integrally formed, and the first conductive sheet 123 is subjected to the pressure force from the first elastic member 121 while the second conductive sheet 132 is subjected to the pressure force from the second elastic member 131. In order to prevent the first conductive sheet 123 and the second conductive sheet 132 from being unable to be effectively connected with the wire and the conductive terminal if the first conductive sheet 123 and the second conductive sheet 132 are displaced, the connector seat 100 further includes a conductive sheet installation portion 140 arranged in the electrical cavity 111. The conductive sheet installation portion 140 is integrally formed with the second conductive sheet 123 and has a flat plate shape.
