This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification made to the present embodiment and do not create contribution after reading this specification, but only
It will be in the scope of the claims of the utility model all by the protection of Patent Law.
Embodiment one: the present embodiment is related to a kind of multilayer printed circuit board, as shown in Figure 1, comprising: circuit board body 1, electricity
Be symmetrically arranged with clamping structure 2 on the opposite two sides of road plate ontology 1, clamping structure 2 for realizing adjacent circuit plate ontology 1 it
Between detachable assembly.In other embodiments, it can also be installed using screw between adjacent circuit plate ontology 1, or
Using inserting column memory grafting.
In conjunction with described in Fig. 1,2,3, clamping structure 2 includes: mounting bar 3 and strip 4；The side of mounting bar 3 is provided with card
Slot 5.Strip 4 is set to side opposite with 5 place side of card slot on mounting bar 3, and strip 4 is used for and next circuit board body 1
5 phase of card slot assembly.
In conjunction with described in Fig. 1,2,3, in the present embodiment, mounting bar 3 and circuit board body 1 are integrally formed, strip 4 and installation
Item 3 is integrally formed.Card slot 5 is T-slot, and strip 4 is the T-bar mutually assembled with T-slot.In order to be promoted between T-slot and T-bar
The compactness and fastness of installation, are symmetrically arranged with two pieces of elastic slices 6 on the end face that T-bar is abutted with the slot bottom of T-slot, and two pieces
Edge and T-bar fixing assembling of the elastic slice 6 close to T-bar, two pieces of elastic slices 6 with the cell wall of T-slot for abutting, to be promoted
The stability installed between T-slot and T-bar.
In conjunction with shown in Fig. 4,5, in order to reduce the convenience installed between T-bar and T-slot, by setting on the T-bar
There is mounting groove, rolling assembly 7 is provided in the mounting groove, rolling assembly 7 is used to reduce the friction between T-bar and T-slot.
Rolling assembly 7 includes: ball 8 and sub- pearl 9；8 part of ball is placed in mounting groove, and another part exposes mounting groove and T shape
The cell wall of slot is in rolling contact, and ball 8 is used to the sliding friction between T-bar and T-slot being converted into rolling friction.Sub- pearl 9 sets
Be placed between ball 8 and the slot bottom of mounting groove, sub- pearl 9 for reducing frictional force between ball 8 and slot bottom, meanwhile, sub- pearl 9 it is resistance to
Mill ability is better than the inner wall of mounting groove, and sub- pearl 9 can directly contact to avoid ball 8 with the cell wall of mounting groove, so as to avoid rolling
The abrasion of pearl 8 or mounting groove.
In conjunction with shown in Fig. 4,5, in the present embodiment, eight groups of rolling assemblies 7, every group of rolling group are provided on a T-bar
