Description

Connector for LED module substrate
Technical Field
The present invention relates to a connector for electrical connection of a chip-on-board type LED module substrate.
Background
A COB (Chip on board) type LED module substrate in which an LED element is mounted on a substrate is used in the field of lighting and the like.
In this case, a connector for supplying power to the LED module substrate is used.
For example, patent document 1 discloses a cap assembly in which a deflection terminal provided on a cap is brought into contact with an anode and a cathode of an LED array (LED module substrate) and the cap is fixed to a support to sandwich the LED array.
However, in the structure in which the LED module substrate is vertically sandwiched by the cover, the support, and the like, the contact pressure of the deflection terminal (connection terminal) of the power supply terminal, which elastically contacts the power supply pad of the LED module substrate, is changed by the fastening force of the screw.
Further, a structure in which an upper cover member and a lower cover member are provided separately in advance and the LED module substrate is sandwiched between the upper and lower cover members is conceivable, but in this case, the upper cover member and the lower cover member need to be managed separately and need to be packaged separately at the time of transportation.
In addition, the contact may be accidentally brought into contact with a connection terminal (contact) provided in the upper cover member and deformed.

Disclosure of Invention
The invention aims to provide a connector which is easy to hold and electrically connect an LED module substrate and has high reliability of electrical connection.
The connector for an LED module substrate according to the present invention is a connector for holding an LED module substrate and performing electrical connection, comprising a lower cover member for placing an LED module substrate thereon, and an upper cover member rotatably attached to an end portion of the lower cover member, wherein the upper cover member has 2 connection terminals for power supply which are elastically contacted with a power supply pad provided in the LED module substrate, the connection terminals extend in a direction not orthogonal to a rotation direction of the cover member, and contact portions of the 2 connection terminals are provided at mutually different distances from a rotation center of the upper cover member and a rotation center of the lower cover member, and the contact portions of the connection terminals are elastically connected to a surface of the power supply pad while sliding in both directions of an elastic displacement direction of the connection terminals and the rotation direction of the upper cover member with respect to a surface of the power supply pad, the contact portion closer to the rotation center approaches the light emitting portion of the LED module substrate as the rotation proceeds.
Here, the structure for rotatably attaching the upper cover member to the lower cover member is not limited, and for example, the upper cover member and the lower cover member are hingedly coupled to each other at the end portions thereof by a hinge structure.
There is no limitation on other connection structures such as hinge structure, shaft joint, and pivot joint.
The present invention holds an LED module substrate by upper and lower cover members by placing the LED module substrate on a lower cover member and rotating an upper cover member to close the LED module substrate toward the lower cover member.
Thus, the power supply connection terminal provided on the upper cover member slides on the surface of the power supply pad of the LED module substrate and elastically contacts the surface in accordance with the rotation of the upper cover member, and the contact portion performs a self-cleaning function.
In this case, the connection terminal extends in a direction not orthogonal to the rotation direction of the upper cover member, and when the upper cover member is rotated in the closing direction, the contact portion of the connection terminal is elastically connected to the surface of the power supply pad while sliding in both the elastic displacement direction of the connection terminal and the rotation direction of the upper cover member with respect to the surface of the power supply pad, and the contact portion generates a stronger self-cleaning action.
Here, the term "the connection terminal extends in a direction not orthogonal to the rotation direction of the upper cover member" means that, for example, when an elastic piece having a tip portion serving as a free end of the contact portion extends from a contact provided on the upper cover member for connection to an external power supply, the extending direction is not orthogonal to the rotation axis direction of the upper cover member.
The present invention has the following effects.
In the connector according to the present invention, since the upper cover member is rotatably attached to the lower cover member in advance, the upper and lower cover members can be managed integrally, and the connection terminals provided on the inner side of the upper cover member are not accidentally brought into contact with each other and deformed.
Further, since the connection terminal of the upper cover member slides on and is connected to the power supply pad of the LED module board in accordance with the rotation of the upper cover member, a self-cleaning function is generated, and the reliability of the electrical connection is high.

Detailed Description
Hereinafter, a structural example of a connector according to the present invention will be described with reference to the drawings, but the present invention is not limited thereto.
As shown in fig. 1 and 2, the connector according to the present invention is configured such that a rotatable upper cover member 10 is coupled to an end portion of a lower cover member 20 via a hinge structure, wherein the lower cover member 20 has a mounting portion 21 for mounting and mounting an LED module board 30 thereon.
Although the hinge structure is not limited, in the present embodiment, as shown in fig. 4, a pair of pivot protrusions 22 are disposed opposite to each other at the end of the lower cover member 20, and a pair of pivot recesses 12 are provided at the corresponding end of the upper cover member 10.
Thus, the upper cover member 10 can be rotated relative to the lower cover member 20 by fitting and pivoting the pivot convex portion 22 of the lower cover member 20 into the pivot concave portion 12 of the upper cover member 10.
In fig. 1, the pivot axis is shown by a chain line as a rotation center O.
The lower cover member 20 has a mounting portion 21 for mounting the LED module board 30 thereon, and the LED module board 30 is mounted on this portion.
The LED module board 30 includes a light emitting portion 31 in which an LED element is packaged, and power supply pads 32 and 33 for supplying power to the packaged LED element.
In addition, in order to mutually determine the mounting positions when the LED module board 30 is mounted on the lower cover member 20, positioning recesses 34a and 34b are provided at the corners of the LED module board, and positioning protrusions 21a and 21b are provided at the corners of the mounting portion 21 of the lower cover member 20.
The upper cover member 10 has an opening 11 for emitting light emitted from the light emitting section 31 of the LED module board 30 to the outside, and contacts 13 and 14 for connection to an external power source via a cable or the like.
As shown in fig. 3, in the present embodiment, the contacts 13 and 14 include connection portions 13b and 14b into which core wires of a connection cable are inserted, and connection terminals 13a and 14a each including a leaf spring-like elastic piece serving as a free end from a main body portion of the contact.
The connection terminals 13a and 14a are arranged at a predetermined angle (including parallel to the pivot axis direction) so that the extending direction of the free ends from the joint portion of the contact body portion is not orthogonal to the pivot axis direction (pivot axis direction).
Fig. 1(c) and 3 show the operation of the contact portions when the upper cover member 10 is closed and the connection terminals 13a and 14a are brought into elastic contact with the power feeding pads 32 and 33 of the LED module board 30.
Since the connection terminals 13a, 14a which become free ends extend as elastic pieces from the contacts 13, 14 attached to the upper cover member 10, in the present embodiment, the one connection terminal 14a on the side close to the rotation center O is first brought into elastic contact with the power feeding pad 33, and the other connection terminal 13a on the side far from the rotation center O is then brought into elastic contact with the power feeding pad 32.
The contact portions 113a and 114a of the connection terminals 13a and 14a are subjected to a sliding force in an elastic displacement direction in accordance with the elastic deformation of the connection terminals, and a sliding force moving in a rotational direction from the rotational center side toward the free end side of the upper cover member 10 by the rotation of the upper cover member 10 in the closing direction, and the resultant of the vectors slides in the oblique arrow direction.
This also slides in the rotational direction other than the elastic displacement direction of the connection terminals 13a and 14a, and therefore the self-cleaning action of the contact portions is high.
When the module board 30 is held by the upper and lower cover members 10 and 20 in advance and the upper cover member 10 is closed so that a stable contact pressure of the power supply pad part can be secured, the engaged parts 15a and 15b provided on the upper cover member 10 and the engaging parts 23a and 23b provided on the lower cover member 20 are engaged with each other.
In order to facilitate the opening and closing operation, as shown in fig. 2, the handle portions 24a and 24b are provided upright on both sides of the lower cover member 20 and are easily gripped with fingers.
As shown in fig. 5, the LED module board 30 is fixed to the heat sink 1 or the like by fixing tools 4a, 4b such as screws through mounting holes 16a, 16b provided in the upper cover member 10 in a state where the LED module board is mounted on the connector.
Next, the core wires of the cables 2, 3 are inserted into the connection portions 13b, 14b connected to the contacts 13, 14.
