Abstract
Description
Technical Field
[0001] This utility model specifically relates to an automotive lamp holder. Background Technology
[0002] Automotive lamp holders are an important component of automotive lighting systems, primarily used to secure and connect bulbs, ensuring their proper functioning. They are commonly used in brake lights, turn signals, and reversing lights. However, existing automotive lamp holders suffer from complex structural designs, unreliable bulb-to-holder connections, and a tendency for momentary disconnections in the bulb-to-holder terminals when subjected to vibration. Furthermore, these lamp holders are prone to performance instability and cumbersome assembly. Summary of the Invention
[0003] The purpose of this utility model is to overcome the defects of the prior art and provide an automotive lamp holder that is simple in structure, stable and reliable in performance, reliable in connection and convenient in assembly.
[0004] To achieve the above objectives, this utility model employs an automotive lamp holder, comprising a base body, a fastener disposed within the base body and cooperating with a light bulb, and two contact terminals respectively disposed within the base body and in contact with the light bulb. The fastener has two elastic fastening arms extending into the mounting cavity of the base body at both ends. The tail portions of the two elastic fastening arms are respectively provided with two arc-shaped protrusions that cooperate with the light bulb. The light bulb is provided with two anti-detachment bosses that cooperate with the two arc-shaped protrusions of the two elastic fastening arms. The two arc-shaped protrusions are fastened to the two anti-detachment bosses, forming a limiting cooperation between the two arc-shaped protrusions and the two anti-detachment bosses.
[0005] The beneficial effects of the above structure are: the fastener is engaged with the bulb via two elastic locking arms; when the bulb is inserted into the mounting cavity of the socket, the arc-shaped protrusions of the two elastic locking arms engage with the two anti-disengagement protrusions of the bulb, thus ensuring a more reliable connection between the bulb and the socket. Therefore, this automotive lamp socket has the advantages of simple structure, stable and reliable performance, reliable connection, and convenient assembly.
[0006] Specifically, the two elastic locking arms are provided with two anti-detachment tabs, and the mounting cavity of the seat is provided with two limiting grooves that cooperate with the two anti-detachment tabs. The two anti-detachment tabs are engaged in the two limiting grooves, forming a limiting fit between the two anti-detachment tabs and the seat. The two anti-detachment tabs can play a role in preventing loosening, ensuring a tighter and more secure connection between the buckle and the seat.
[0007] Specifically, one side of the anti-detachment protrusion is provided with an insertion guide slope that mates with the arc-shaped protrusion, and the other side of the anti-detachment protrusion is provided with a pull-out limiting plane that mates with the arc-shaped protrusion. The arc-shaped protrusion slides along the insertion guide slope and engages with the pull-out limiting plane. The insertion guide slope guides the arc-shaped protrusion, which helps to reduce the insertion force, while the pull-out limiting plane limits the arc-shaped protrusion, which helps to increase the pull-out force, thereby ensuring a tighter and more secure connection between the bulb and the base.
[0008] Specifically, one end of each of the two contact terminals has two crimping portions extending outside the housing and connected to two wires. The other end of each of the two contact terminals has two contact springs extending inside the mounting cavity and engaging with the two power lines of the bulb. The two contact springs abut against the two power lines, achieving electrical connection between the two contact springs and the two power lines. The two contact terminals contact the two power lines of the bulb through the two contact springs, employing an elastic contact structure, thereby ensuring more reliable contact between the two contact terminals and the bulb's power lines.
[0009] Specifically, the two contact terminals are provided with two limiting pieces extending into the mounting cavity, and the mounting cavity of the base is provided with two positioning grooves that mate with the two limiting pieces. The two limiting pieces are respectively inserted into the two positioning grooves, forming a limiting fit between the two limiting pieces and the base. The two limiting pieces of the contact terminals are engaged in the positioning grooves of the base, thereby ensuring a tighter and more secure connection between the two contact terminals and the base.
[0010] Specifically, the mounting cavity of the base is provided with two limiting steps that mate with the bulb, and two limiting blocks that mate with the limiting steps are provided on both sides of the bulb. When the bulb is inserted into the mounting cavity, the two limiting blocks abut against the two limiting steps. The two limiting steps of the base serve a limiting function, and when the bulb is inserted into the mounting cavity, the two limiting blocks abut against the two limiting steps, thereby ensuring a tighter connection between the bulb and the base.

[0015] like Figures 1-4 As shown, this utility model embodiment is an automotive lamp holder, including a base 10, a fastener 12 disposed within the base 10 and cooperating with a bulb 11, and two contact terminals 13 respectively disposed within the base 10 and in contact with the bulb 11. The fastener 12 has two elastic fastening arms 121 at both ends extending into the mounting cavity 100 of the base 10. The tails of the two elastic fastening arms 121 are respectively provided with two arc-shaped protrusions 122 that cooperate with the bulb 11. The bulb 11 is provided with two anti-detachment bosses 111 that cooperate with the two arc-shaped protrusions 122 of the two elastic fastening arms 121. The two arc-shaped protrusions 122 are fastened to the two anti-detachment bosses 111, and a limiting cooperation is formed between the two arc-shaped protrusions 122 and the two anti-detachment bosses 111. Two anti-detachment tabs 123 are provided on the two elastic fastening arms 121. Two limiting grooves 101 are provided in the mounting cavity 100 of the seat body 10 to cooperate with the two anti-detachment tabs 123. The two anti-detachment tabs 123 are engaged in the two limiting grooves 101, forming a limiting fit between the two anti-detachment tabs 123 and the seat body 10. The two anti-detachment tabs can prevent loosening, ensuring a tighter and more secure connection between the fastener and the seat body. An insertion guide slope 1111 is provided on one side of the anti-detachment boss 111 to cooperate with the arc-shaped protrusion 122. A pull-out limiting plane 1112 is provided on the other side of the anti-detachment boss 111 to cooperate with the arc-shaped protrusion 122. The arc-shaped protrusion 122 slides along the insertion guide slope 1111 and engages with the pull-out limiting plane 1112. The insertion guide bevel acts as a guide for the arc-shaped protrusion, which helps to reduce the insertion force. The pull-out limiting plane acts as a limit for the arc-shaped protrusion, which helps to increase the pull-out force, thus ensuring a tighter and more secure connection between the bulb and the base.
[0016] like Figures 2-4As shown, one end of each of the two contact terminals 13 has two crimping portions 131 extending outside the base 10 and connected to two wires 14. The other end of each of the two contact terminals 13 has two contact springs 132 extending inside the mounting cavity 100 and cooperating with the two power lines 112 of the bulb 11. The two contact springs 132 abut against the two power lines 112, achieving electrical connection between the two contact springs 132 and the two power lines 112. The two contact terminals contact the two power lines of the bulb through the two contact springs, employing an elastic contact structure, thereby ensuring more reliable contact between the two contact terminals and the power lines of the bulb. The two contact terminals 13 are provided with two limiting pieces 133 extending into the mounting cavity 100. The mounting cavity 100 of the base body is provided with two positioning grooves 102 that mate with the two limiting pieces 133. The two limiting pieces 133 are respectively inserted into the two positioning grooves 102, forming a limiting engagement between the two limiting pieces 133 and the base body 10. The two limiting pieces of the contact terminals are engaged in the positioning grooves of the base body, thereby ensuring a tighter and more secure connection between the two contact terminals and the base body.
[0017] The mounting cavity 100 of the base 10 is provided with two limiting steps 103 that cooperate with the bulb 11. Two limiting blocks 113 that cooperate with the limiting steps 103 are provided on both sides of the bulb 11. When the bulb 11 is inserted into the mounting cavity 100, the two limiting blocks 113 abut against the two limiting steps 103. The two limiting steps of the base serve a limiting function; when the bulb is inserted into the mounting cavity, the two limiting blocks abut against the two limiting steps, thus ensuring a tighter connection between the bulb and the base.
[0018] The fastener is secured to the bulb via two elastic locking arms. When the bulb is inserted into the mounting cavity of the socket, the arc-shaped protrusions of the two elastic locking arms engage with the two anti-disengagement protrusions of the bulb, thus ensuring a more reliable connection between the bulb and the socket. Therefore, this automotive lamp socket has the advantages of simple structure, stable and reliable performance, reliable connection, and convenient assembly.
