The shielding case is positioned smoothly with good stability during the assembly; and the positioning clamp is endowed with the guiding function during the assembly, thereby facilitating the assembly of the shielding case.
Description
Technical field:
The utility model relates to the shielding device of network connector, a kind of SFP network connector shielding case of saying so exactly.
Background technology:
The SFP shielding case is used for the fiber optic network connector apparatus, plays shielding action, and it is made and requires is to meet optical-fibre channel, gigabit Ethernet and InfiniBand* standard.
The existing SFP shielding case that is used for according to the needs of structure and use, has two kinds of forms.A kind of is welded type, is welded direct on the pcb board, is uneven but this product is prone to welding when wave-soldering, and tin boiling itself and stove hot gas cause product floating high in the tin stove.And difficult production operation, the quality instability can not satisfy the quality requirements of high-end product, and performance is not too latent fixed; Another kind of compression joint type is commonly called as riveting type.Be directly with the riveting tool PIN pin to be pressed into pcb board by force, circuit forms conducting naturally, and need not weld again.No left and right sides detent mechanism in the middle of the product bottom when shortcoming of this frame mode is riveting, need during riveting the correcting shielding case till, the riveting operation is not very smooth and easy.
The utility model content:
In order to overcome above-mentioned defective, the purpose of this utility model is to provide a kind of shielding case of the SFP of being used for connector, and this shielding case is simple in structure, easily welding, and reliability is good, the suitable batch work production.
In order to achieve the above object, the utility model is achieved in that
A kind of shielding case that is used for the SFP connector, it includes housing, lower housing portion is provided with card base, it is characterized in that described housing lower surface is provided with locator card, and this locator card protrudes in surface of shell, and identical with described screens highly at least.
This shielding case by the setting of locator card, can the time be located smoothly in assembling, good stability, and locator card can also lead when assembling, is convenient to the assembling of shielding case.
Described locator card, it is a platy structure, is convenient to guiding to make in the location.
Described locator card, it is provided with 2 at least, positions guiding can make shielding case when combining with pcb board.
Described locator card, it is half serpentine structure, with the accuracy of increase location, and has guidance quality.
Described shielding case, its lower housing portion both sides are provided with screens, screens is a platy structure, and be arranged at the same horizontal line of card base on, be convenient to the time block pcb board in assembling.
Above-mentioned screens, its horizontal both sides have outstanding guide protrusions, and along the direction of assembling, the guiding that can be well on of the guide protrusions in the screens is convenient to the assembling of shielding case.
In order to increase the accuracy of location, described locator card is provided with three, becomes " product " font to be distributed in the bottom surface of housing.
Specifically, above-mentioned structure is when being applied to welded type SFP shielding case: increase screens respectively at bottom outside the right and left PIN pin, the effect of this screens has two, one is to block PCB, solving product causes product to float high phenomenon because of tin boiling itself and stove hot gas in the tin stove through wave-soldering the time, the screens front end also has guide function, can play the effect of being convenient to plug, and makes plug more smooth and easy.Increase by three left and right sides locator cards at shielding case bottom zone line in addition, make product when plug, not only play guide effect, and plug can be more smooth and easy.
When being applied to riveting and making the SFP shielding case: zone line increases by three left and right sides locator cards in the product bottom, make product not only play guide effect when plug, and plug can be more smooth and easy.
Description of drawings:
Fig. 1 is the stereographic map of the utility model embodiment one,
Fig. 2 is the structural representation of the shielding case bottom of mode shown in Figure 1,
Fig. 3 is the structural representation in shielding case when assembling of mode shown in Figure 1,
Fig. 4 is the stereographic map of the utility model embodiment two,
Fig. 5 is the structural representation of the shielding case bottom of mode shown in Figure 4,
Fig. 6 is the structural representation in shielding case when assembling of mode shown in Figure 4.
Embodiment:
Below, in conjunction with the accompanying drawings enforcement of the present utility model is elaborated.
Fig. 1-shown in Figure 3, for the utility model is applied to the structural representation of welded type SFP shielding case, among the figure, the housing 10 of this shielding case is a box like structure, the both sides of its bottom have the card base 11 that stretches out downwards, to carry out welding assembly.
Wherein, be positioned at same horizontal housing 10 both sides with card base 11, also be provided with screens 12, screens 12 is a platy structure, and a side of screens 12 has outstanding guide protrusions, makes screens 12 1 can block pcb board, solves product and causes product to float high phenomenon because of tin boiling itself and stove hot gas in the tin stove through wave-soldering the time, two by guide protrusions, makes plug more smooth and easy.
It is shown in Figure 2 again, and the bottom of housing 10 has three locator cards 13 that are " product " font structure distribution, this locator card 13 is tabular, and has certain arc, forms the structure of half " S " shape, make shielding case when plug, not only play guide effect, and plug can be more smooth and easy.
Shown in Figure 3, when housing 10 was assembled with pcb board 14, under the effect of locator card 13 and screens 12, housing 10 can be aimed at the assembly hole on the pcb board 14 smoothly, the situation of the pin that is installed can not occur missing.This structural design is the pcb board of compatible different-thickness simultaneously, and solves and floating high phenomenon that prevention may exist in processing procedure, and the lifting quality is enhanced productivity, and cuts down finished cost.
Fig. 4-shown in Figure 6, for the utility model is applied to the structural representation of riveting type SFP shielding case, among the figure, the housing 20 of this shielding case is a box like structure, the both sides of its bottom have the card base 21 that stretches out downwards, to carry out welding assembly.
Shown in Figure 5, in this mode, only set up locator card 22 on the lower surface of housing 20, and locator card 22 is tabular, and has certain arc, forms the structure of half " S " shape, locator card 22 has three, arranges at zone line formation " product " font of housing 20 lower surface.
Shown in Figure 6, when this shielding case and pcb board assembling, under the effect of locator card 23, housing 20 can be aimed at the assembly hole on the pcb board 23 smoothly, and this structural design not only plays guide effect when plug, and plug can be more smooth and easy.
Simultaneously, two kinds of above-mentioned embodiments, described shielding case adopts Cu alloy material, utilizes effective arrangement design of reasonable structural design and grounding leg position to improve data transmission, prevents the interference of external magnetic field.
In a word, the said goods has the following advantages:
1, reasonable in design has solved the existing floating height of existing product technology and difficult plate problem, makes product have more stability.
2, structural design has compatibility, utilizes the design of locator card, has effectively solved unsettled phenomenon in the shielding case assembling process, is convenient to rapid processing, promotes quality, can carry out a large amount of batch machining, enhances productivity, and cuts down finished cost.
