Preferably, the signal transmission part is copper post, one end of the copper post is screwed fixing end, copper post
The other end is equipped with and is screwed into end face.
Preferably, the fixing end of the signal transmission part penetrates the hole that pcb board is opened up, and tightened admittedly by nut
So that pcb board is tightly attached on panel surely.
Preferably, one end of the spring and the bottom connection of through-hole touch, the other end is screwed into signal transmission part
End face is in contact, and when signal transmission part is tightened, spring is in compressive state.
It is opened with what outer signals connector contacted for signal transmission part preferably, being offered on the pallet end face
Mouthful.
Preferably, the signal transmission part is at least provided with two.
The beneficial effects of the utility model are：Flexible dress is installed on the pallet of signal transmission part with contact copper sheet one end
It sets, keeps signal connection to be maintained at stable state by spring force, avoiding contact firmly from generating abrasion leads to poor contact.
Description of the drawings
Fig. 1 is the overall structure diagram of the utility model.

Opening；21, through-hole；31, spring；32, nut；41, hole；51, fixing end；52, it is screwed into end face.
Specific implementation mode
Detailed introduction is done to the utility model below in conjunction with attached drawing：As shown in Fig. 1, the utility model includes pallet
1, a panel 2 is installed on the pallet 1, and elastic device 3 is equipped with by the panel 2；The elastic device 3
On at least two signal transmission parts 5 are installed, the signal transmission part 5 is connect with 4 signal of signal source；The signal source 4
Including pcb board or other signal parts with equivalent effect, the signal transmission part 5 is in contact with the pcb board to be used in combination
Signal is transmitted, which is located at the lower end of elastic device 3, and positioned at the lower section of panel 2；It is opened on 1 end face of pallet
Equipped with the opening 11 contacted with outer signals connector for signal transmission part 5, and the opening 11 by being opened up on 1 end face of pallet
Facilitate the signal transmission of signal transmission part 5；Made by the elastic force of the spring 31 because including spring 31 in elastic device 3
Signal transmission part 5 on elastic device 3 remains a contact resilient power when being in contact with another contact, makes
It obtains and is in stable state between the two, avoiding contacting firmly generating to wear leads to poor contact.
The elastic device 3 includes spring 31, nut 32, which is mounted in the through-hole 21 that panel 2 is opened up,
And signal transmission part 5 is mounted in spring 31, and nut 32 is used in combination to limit, the spring 31 after limit is in compressive state；Also it can adopt
With with nut 32 there is the fixing piece of same fixed effect to replace therewith, spring 31 can be made to protect always by the fixed structure mode
It holds in the through-hole 21 that panel 2 is opened up so that spring 31 obtains limit on axial position and fixes；Wherein the spring 31 can
The elastic component with equivalent effect is thought to replace.
The signal transmission part 5 is copper post, and one end of the copper post is screwed fixing end 51, and the end carries M3
Screw thread, the other end of copper post, which is equipped with, is screwed into end face 52；Signal transmission part 5, which may be other, has the Transmission Part that can transmit signal
To replace this copper post.
The fixing end 51 of the signal transmission part 5 penetrates the hole 41 that pcb board is opened up, and tightens fixation by nut 32
Pcb board is set to be tightly attached on panel 2.
One end of the spring 31 is touched with the bottom connection of through-hole 21, and the other end is screwed into end face with signal transmission part 5
52 are in contact, and when signal transmission part 5 is tightened, spring 31 is in compressive state；During sound column use, in order to make signal pass
Defeated part 5 is in signal connection status always with another contact, and the spring 31 for being now in compressive state can slow release tension
To keep signal connection status.
The operation principle of the utility model is：Signal transmission part 5 is sleeved in spring 21, is used in combination nut 32 by signal transmission
Part 5 is tightened with pcb board, and spring 21 is in complete compressive state at this time, and signal transmission part 5 be screwed into end face 52 toward
The opening 11 opened up on 1 end face of pallet；When sound column connects, as long as by end face 52 is screwed on the signal transmission part 5 of sound column
The signal connector that panel is installed with sound column is in contact, and then transmits a signal to signal transmission part 5 by pcb board, and
The signal connector that sound column installs panel is transmitted a signal to by signal transmission part 5.
The utility model is not limited to the above embodiment, makees any variation no matter being constituted in its shape or material, all
