Description

Spring clip-type speaker terminal for sound equipments {A Structure For Sealant Connecting Speaker Terminal Of Spring Clip Type For Sounder}

The present invention relates to a speaker terminal sealed connection structure for sealingly installing a speaker terminal connected to a speaker wire to the rear side of an acoustic device, and more specifically, bonding a shielding cushion to a spring clip type speaker terminal to which the speaker wire is connected. The terminal insertion hole is formed on the rear side of the sound equipment so that the connection terminal of the terminal can be inserted so that the speaker terminal can be sealedly installed outside the sound equipment to structurally change the sound that may occur when air flows through the assembly gap. A spring clip type speaker terminal hermetic connection structure for an acoustic device can be reduced.

Generally, the speaker cable connection terminal of the speaker has a spring clip type and a binding post terminal type, and the expensive speaker or receiver has a binding post for easy detachment, attachment, and accurate connection. The terminal of type is null.

In addition, several methods are used to connect the speaker wire to the reserver or the speaker. The simplest method is a method of directly connecting the speaker wire to the spring clip type connection terminal, but the spade connector (for easy attachment and detachment and accurate connection) is used. Spade Connectors, Pin Type Connectors, Banana Plugs, and the like are used.

In addition, shield, called shielding, prevents unnecessary noise, and there are various kinds of objects to be prevented. For example, an electromagnetic shield that blocks electromagnetic waves generated in a far-field electromagnetic field, and an electromagnetic shield that induces an inductive bond.

On the other hand, the spring clip-type speaker terminal so far, as shown in the use state diagram of Figure 4, the hole until the terminal housing 112 of the speaker terminal 110 is inserted into the rear side of the sound device 130 can be fixed Formed so that the middle portion of the terminal housing 112 is fixed in position to be coupled to the hole.

However, a method of exposing the terminal housing 112 from the inside of the acoustic device 130 to the outside by forming a hole in the acoustic device 130 to the extent that the terminal housing 112 can be inserted is substantially Irrespective of the connection terminal 116 to which the speaker wire (not shown) is connected, the size of the hole was larger than necessary because the hole should be formed as large as the size of the speaker terminal 110, and the sound device 130 As airtightness between the holes and the speaker terminal 110 is lowered between the holes and the speaker terminal 110, the precision of the acoustic device is reduced due to the change of sound.

The present invention is to solve the problems as described above, by forming a terminal insertion hole in the rear side of the sound equipment only enough to be connected to the connection terminal of the speaker terminal sealed installation of the speaker terminal bonded shielding cushion outside the sound equipment The spring clip-type speaker terminal sealed connection structure for sound equipment can be improved by structurally preventing air from passing through these assembly gaps, thereby minimizing the change of sound caused by air resistance, and dramatically improving the precision of sound equipment. The purpose is to provide.

Spring clip-type speaker terminal hermetic connection structure for the sound device of the present invention for achieving the above object, the sealing cushion is bonded to the shield housing on the rear side of the terminal housing of the speaker terminal protruding the connection terminal connected to the sound device on the opposite side of the pushbutton The terminal insertion hole is formed through the rear side of the sound device in such a size that only the connection terminal of the speaker terminal can be inserted, and the connection terminal of the speaker terminal is inserted into the terminal insertion hole of the sound device to mediate the closed cushion. Furnace assembly is characterized in that the coupling is fixed to be sealed.

In addition, the closed cushion is characterized in that the through-hole is formed so that the through-hole is passed through the bonding when the screw through-hole is formed to correspond to the through-hole formed in the terminal housing.

Hereinafter, with reference to the accompanying drawings for a preferred embodiment of the present invention will be described in detail the configuration and effect.

1 and 2 are the combined state in which the sealed cushion 20 according to the present invention is bonded and bonded as a shielding bond 26 to the rear side of the terminal housing 12 of the speaker terminal 10 and the shielding bond 26 is applied. The rear side of the terminal housing 12 is a separate state before the bonding of the sealed cushion 20 is bonded, respectively, Figure 3 is a speaker terminal 10 bonded to the sealed cushion 20 in accordance with the present invention is a sound device The cross-sectional view shows a use state in which only the connection terminal 16 is inserted into the terminal insertion hole 32 of 30 to be coupled and fixed.

As shown in Figures 1 and 2, the splicing-type speaker terminal 10 of the present invention is a speaker terminal protruding the connection terminal 16 is connected to the sound device 30 on the opposite side of the push button 14 ( The rear end of the terminal housing 12, the sealing cushion 20 is bonded to the secondary sealed bond (26).

That is, a shield bond 26 is applied to the rear side of the terminal housing 12 of the speaker terminal 10 in which the connection terminal 16 for applying a power signal to the sound device 30 protrudes and the screw through hole 18 is formed. Meanwhile, a flexible material having a size formed in accordance with the rear side area of the terminal housing 12 and having a terminal passage hole 22 and a screw passage hole 24 penetrated in accordance with the connection terminal 16 and the terminal passage hole 18. The sealed cushion 20 is attached to the shield bond 26 of the rear side of the terminal housing 12 and bonded.

At this time, the connection terminal 16 of the speaker housing 12 is exposed and inserted into the terminal through-hole 22 of the sealed cushion 20, and at the position of the screw through hole 18 of the speaker housing 12, the sealed cushion Of course, the screw passing hole 22 of 20 is positioned.

As described above, the speaker terminal 10 of the present invention, in which the closed cushion 20 is bonded to the rear side of the terminal housing 12, is connected to the terminal insertion hole 32 of the acoustic device 30 as shown in FIG. 3. By inserting the connection terminal 16 of the terminal 10 to ensure that the sealed cushion 20 of the speaker terminal 10 is securely sealed to the rear side of the sound device 30, the sound device 30 of the In a state in which the speaker terminal 10 is in close contact with the rear side, a separate screw may be fastened to the screw passing hole 18 of the speaker terminal 10 to be coupled and fixed from the inside of the sound apparatus 30.

Therefore, the shielding cushion 20 is bonded to the spring clip type speaker terminal 10 to which the speaker wires (not shown) are connected, and the sound device is provided so that the connection terminal 16 of the speaker terminal 10 can be inserted. The terminal insertion hole 32 is formed on the rear side of the device 30, so that the speaker terminal 10 can be easily sealed and installed outside the sound device 30, which results in an assembly gap between the sound device 30 and the speaker terminal 10. This prevents air from passing through, which can dramatically reduce sound changes caused by air resistance.

As described above, according to the hermetic connection structure of the spring clip type speaker terminal for the sound device of the present invention, the shielding cushion is bonded to the spring clip type speaker terminal to which the speaker wire is connected, so that the connection terminal of the speaker terminal can be inserted into the speaker unit. The terminal insertion hole is formed on the rear side so that the speaker terminal can be sealedly installed outside the sound equipment, thereby structurally reducing the sound change that can occur when air flows through the assembly gap, thereby improving the precision of the sound equipment. have.
