Description
Technical field
The utility model relates to the encapsulation technology field of charactron, refers specifically to the combination hub protection knot on a kind of wiring board
Structure.
Background technology
Existing LED charactron typically uses PIN needle realizing the function of pin, but client is for erection & lift efficiency
And the convenience installed, start to use PIN needle instead combination hub and realize.
For example, Authorization Notice No. is Chinese utility model patent " a kind of interconnection system charactron " (Shen of CN204650936U
Please number: CN201520206808.5) i.e. disclosing a kind of such structure, this structure includes pcb board, REF and is encapsulated in REF
LED chip, REF and pcb board be connected, and the pcb board back side is provided with plug connector, and plug connector electrically connects with pcb board, and REF sets with pcb board
Put in integral type, can be attached with other circuit on circuit board by plug connector, facilitate the assembly and disassembly of product, by it
It is arranged on end product, be also convenient for keeping in repair after sale.But, when LED charactron assembles, need embedding epoxy in housing
Resin, owing to the material of current combination hub typically uses LCP material, and LCP material is different from the coefficient of expansion of epoxy resin, this
Result in the product being completed and be susceptible to cracking in reliability cold shock test, affect the qualification rate of product.
Utility model content
Technical problem to be solved in the utility model is the present situation for prior art, provides a kind of simple in construction to close
Reason, the combination hub that can effectively improve on the wiring board of product percent of pass protection structure.
The technical scheme that the above-mentioned technical problem of the utility model solution is used is: the combination hub protection on a kind of wiring board
Structure, described combination hub is located on wiring board, it is characterised in that: described protection structure includes being nested with the guarantor in combination hub periphery
Sheath, this protection set side has the breach that the exit for combination hub exposes, outside the inwall of described protection set is with combination hub
It is formed with a gap between wall, in this gap, be filled with epoxy resin.
As preferably, the width in described gap is 0.13～0.18mm, more preferably 0.15mm.This excesssive gap meeting
Reducing the protective action of protection set butt-joint socket outer wall, this gap is too small, can affect the loading of epoxy resin in gap, enter
And affect the bonding strength between protection set and combination hub, and use preferred gap width of the present utility model, then avoid
State the appearance of problem.
Preferably, the thickness of described protection set is 1.3～1.7mm, more preferably 1.5mm.The utility model is selected
PPO material makes protection set, and the thickness of protection set is crossed conference and caused waste of material, and thickness is too small, does not has the anti-of needs
Protect effect, select above-mentioned thickness, can guarantee to save material usage on the basis of protective action is good.
In above-mentioned each preferred version, described protection puts and has the mouth of stepping down being connected with combination hub for external lug, should
Mouth of stepping down is opened on the described protection set sidewall relative with breach.Use such structure, be not only convenient for by external lug with
Combination hub connects, and also further saves the material usage of protection set, reduces cost.
Compared with prior art, the utility model has the advantage of: the utility model provides a kind of simple and reasonable for structure
Combination hub safeguard structure, be nested with the protection set in combination hub periphery and there is preferable intensity, and this protection set and combination hub it
Between be filled with a small amount of epoxy resin, on the one hand certain fixation can be played to protection set, on the other hand, increase two
Cushioning effect between person, so that the charactron after Zu Zhuaning can pass through reliability cold shock test, effectively improves product
The qualification rate of product.

Fig. 2 is the part-structure schematic diagram of Fig. 1；
Fig. 3 is the structural representation protecting set in Fig. 1；
Fig. 4 is the structural representation of another angle of Fig. 3.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As shown in Figure 1, 2, combination hub 2 is located on wiring board 3, the combination hub protection structure bag on the wiring board of the present embodiment
Including the protection set 1 being nested with in combination hub 2 periphery, this protection set 1 side has the breach that the exit 21 for combination hub 2 exposes
11, it is formed with a gap 4 between the inwall of protection set 1 and the outer wall of combination hub 2, in this gap 4, be filled with epoxy resin.Such as figure
3rd, shown in 4, protection set 1 having the mouth 12 of stepping down being connected for external lug with combination hub 2, this mouth 12 of stepping down is opened in protection set
On 1 sidewall relative with breach 11, this mouth 12 of stepping down is not only convenient for being connected external lug with combination hub 2, also saves protection
The material usage of set 1, reduces cost.
As shown in Figure 1, 2, the width in gap 4 can be 0.13～0.18mm, and the width of the present embodiment intermediate gap 4 is
0.15mm.The protective action that conference reduces protection set 1 butt-joint socket 2 outer wall is crossed in this gap 4, and this gap 4 is too small, between affecting
Bonding strength between the loading of epoxy resin in gap 4, and then impact protection set 1 and combination hub 2, and use the present embodiment
Gap width, then avoid the appearance of the problems referred to above.The thickness d of protection set 1 can be 1.3～1.7mm, protects in the present embodiment
The thickness d of set 1 is 1.5mm, and the present embodiment selects PPO material to make protection set 1, and the thickness of protection set 1 is crossed conference and caused material
Material waste, thickness is too small, does not has the protective action of needs, selects above-mentioned thickness, can guarantee the good basis of protective action
Upper saving material usage.
The combination hub safeguard structure of the present embodiment is simple and reasonable, is nested with protection set 1 employing in combination hub 2 periphery
PPO material makes, and has between preferable intensity, and this protection set 1 and combination hub 2 and is filled with a small amount of epoxy resin, and one
Protection set 1 can be played certain fixation by aspect, on the other hand, increases cushioning effect therebetween, so that
Charactron after assembling can pass through reliability cold shock test, effectively improves the qualification rate of product.
Including the present embodiment protects the charactron of structure when assembling, and first moulds in shell at the REF of charactron and injects
Then the PCB being mounted with combination hub is put into REF and is moulded shell by liquid-state epoxy resin, treats that PCB sinks to liquid
In epoxy resin, then protection set 1 is enclosed within combination hub 2 periphery, makes liquid-state epoxy resin naturally enter protection set 1 and combination hub 2
Between gap 4 in, solidification dry.
