Description

Technical Field

[0001] This invention relates to the field of sound columns, and more particularly to a safe and stable electrode connection structure that prevents loosening. Background Technology

[0002] A column speaker is a type of sound output device used in modern electronic devices such as computers and portable music players. It is frequently used to reproduce sound effectively and is also employed in broadcasting systems, often outdoors. A typical column speaker consists of four to ten paper cone loudspeakers arranged vertically in sequence. This arrangement gives the column a strong directional characteristic, with particularly pronounced high-frequency directivity. Column speakers are well-suited for use in larger spaces such as parks, plazas, and schools.

[0003] Currently, for sound columns with several adjustable height levels, the circuit connection and disconnection are generally achieved by sliding contact between the female electrode pin on the sound column guide rail and the male electrode pin on the sound column. However, because the sound column vibrates when it produces sound, this connection method is prone to loosening, causing playback to stop. Therefore, it is necessary to improve this structure to overcome the above-mentioned defects. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a safe and stable electrode connection structure that prevents loosening. This invention is achieved through the following technical solution:

[0005] A secure and stable electrode connection structure to prevent loosening includes a guide rail support plate and an electrode female head. A button assembly is slidably disposed on the guide rail support plate. The button assembly can be close to or away from the electrode female head. The button assembly includes a sliding button and an electrode rear cover is also disposed on the button assembly. The sliding button can be close to or away from the electrode rear cover. An electrode front end is fixedly connected to one end of the electrode rear cover near the electrode female head. Two slots are also arranged parallel to each other on the guide rail support plate, and the slots engage with the sliding button.

[0006] In the above technical solution: the guide rail support plate is used to set the remaining structure; the electrode female head is used to connect the circuit; the button assembly is used to control the position of the electrode back cover; the electrode back cover is used to control the position of the electrode front end; the electrode front end and the electrode female head cooperate to realize the cutting and connection of the circuit; the slot is used to restrict the position of the sliding button, so that the electrode front end will not move arbitrarily when not connected and after being connected, thereby avoiding the sudden disconnection of the circuit.

[0007] A further configuration of the present invention is that the button assembly further includes a sliding link and a spring, the sliding link being slidably connected to the sliding button, one end of the spring being sleeved on the sliding link, and the other end being in contact with the sliding button.

[0008] In the above technical solution: the sliding linkage is used to notify the electrode back cover to move, and also to limit the position of the spring; the spring is used to provide elastic force so that the sliding button can engage with the slot in the initial position and the circuit-on position.

[0009] A further provision of the present invention is that an electrode needle female head is provided inside the electrode female head, and an electrode needle male head is provided inside the electrode front end.

[0010] In the above technical solution, the female electrode needle and the male electrode needle achieve circuit disconnection and connection through separation and assembly.

[0011] A further feature of the present invention is that an assembly hole is provided on the lower surface of the electrode rear cover, and the sliding connecting rod is fixedly connected to the assembly hole.

[0012] In the above technical solution: the mounting hole is used to assemble with the sliding link, so that the electrode back cover can be displaced when the sliding button is slid or pressed.

[0013] A further feature of the present invention is that the shape of the female electrode head corresponds to the shape of the front end of the electrode.

[0014] In the above technical solution, the shape of the female electrode head corresponds to that of the front end of the electrode, making it less likely to loosen after assembly and reducing the relative shaking between the two.

[0015] A further feature of the present invention is that two guide rail limiting plates are symmetrically arranged on the guide rail support plate, and the distance between the two guide rail limiting plates is less than the width of the electrode back cover.

[0016] In the above technical solution: the guide rail limiting plate is used to limit the maximum height of the electrode back cover movement.

[0017] A further feature of the present invention is that a first limiting step is provided on the guide rail limiting plate, and a second limiting step is provided on the electrode rear cover, wherein the first limiting step and the second limiting step cooperate with each other.

[0018] In the above technical solution, the setting of the first limiting step and the second limiting step can reduce the left and right offset when the electrode back cover slides horizontally, making the assembly between the electrode front end and the electrode female head smoother.

[0019] This invention discloses a safe and stable electrode connection structure that prevents loosening, compared with the prior art:

[0020] 1. By setting up a slot and button assembly, the present invention enables the electrode tip to be limited by the engagement between the sliding button and the slot after the electrode tip is moved by controlling the sliding button, thereby reducing the possibility of separation between the electrode tip and the electrode head and avoiding the circuit being disconnected unexpectedly.

[0021] 2. The present invention also improves the smoothness of assembly between the electrode front end and the electrode female head by setting a guide rail limiting plate, which makes the movement trajectory of the electrode back cover more stable. Attached Figure Description
