Description

Slim bayonet connector

Technical field

The utility model relates to a kind of slim bayonet connector, espespecially the slotted eye of insulating base frame and the irregularly-shaped hole place of first end subgroup utilize plastics to mold holder overhead kick shape clad structure to inlay shoot mode, can promote first end subgroup engage with insulating base frame after structural strength and heating time ability to thermal deformation resistant, overall structure is more stable.

Background technology

Electronics technology and multimedia messages fast development now, the electronic installations such as computer, notebook computer, panel computer, running gear (MID) are made all to be prevalent in each corner of society, and tend to light, thin, short, little gradually, to be easy to carry about with one and computing and transmission speed are accelerated direction and strided forward, in order to various electronic installation volume-diminished can be made, the electronic component of the inner difference in functionality effect of electronic installation then needs small but excellent close, overall construction intensity also needs to strengthen thereupon, to comply with current development trend.

Moreover, along with electronic installation is applied widely, for periphery expansion board, the demand of the adapter mass data transmission such as display adapter, the bus transfer framework of early stage extended interface has not applied and has used, and in order to solve the problem of the wide deficiency of conventional adaptation cassette tape, just dealer is had to develop PCI Express framework adapter, but the size of this kind of PCI Express adapter is larger, cannot meet for volume and the higher light and thin type running gear of dimensional requirement, institute is to have developed Mini PCI Express, M.2 the adapter of the distinct interface specification such as (or claim NGFF), and this NGFF adapter to have the standard design of different size to make in application more flexible, SATA and PCIe interface can be supported, overall volume is less, more power saving and transmission speed is faster, be used for replacing the usual mSATA interface of light and thin type running gear and become the main flow specification in high-order market.

Because various running gear is all developing direction with light and thin type now, the whole height of the bayonet connector that can insert for Mini PCI Express adapter is in early days 4.0mm, the height reduction of bayonet connector just can be made to reduce the pattern that highly certainly will can only develop into brokenly plate or heavy plate again, and the bayonet connector of the M.2 adapter of new spec is respectively equipped with upper row's terminal and lower row's terminal in insulating base frame upper and lower both sides place, and in lower row terminal part as assembled to interfere the mode of assembling, then insulating base frame need suitable meat thick interfere fixing, certainly will will cannot reach the demand of height reduction, if insulating base frame meat is thick thinning, also can cause assembling and require uprise and be difficult to guarantee overall structural strength.

And in order to reduce the thickness of electric connector, and can effectively solve because meat thick thinning causing interferes assembling mode to derive the problem having Stability Analysis of Structures undercapacity, just dealer is had to develop this kind of bayonet connector, as Fig. 9, Figure 10 shows that three-dimensional exploded view and the part isometric exploded view of existing bayonet connector, wherein this insulating body A inside is provided with slot A0, and be provided with relative the first side wall A1 and the second sidewall A2 in slot A0 both sides place, and the first side wall A1 is provided with the first end pilot trench A11 run through in the face of the internal face of the slot A0 installed surface A10 contrary with internal face, and each first end pilot trench A11 inner position of the first side wall A1 has the first holding parts B1 of the first terminal B, and the second terminal groove A21 of accommodating second terminals C is provided with in the second sidewall A2, the installed surface A10 of another the first side wall A1 is provided with the scrobicula district A12 corresponding to the first holding parts B1 place, and the molten sheet D posting lengthwise in scrobicula district A12, to fix the first holding parts B1 on the first side wall A1, just the thickness of the first side wall A1 can be reduced, and meet the trend of bayonet connector miniaturization.

But, this insulating body A is only molten in the scrobicula district A12 of the first side wall A1 posts sheet D, the scrobicula district A12 of this kind of sheet D and the first side wall A1, the first holding parts B1 of the first terminal B there is no any for mutual buckle, the position engaged, overall construction intensity is comparatively not enough and unstable, time in the slot A0 of external electrical card (not shown) insertion insulating body A, the first contact arm pressurized strain of the first terminal B and be positioned at first end pilot trench A11 and move, just can cause insulating body A and sheet D easily because of the excessive extruding of the first holding parts B1 to produce and be out of shape or the doubt of structural failure, so be difficult to the consideration taken into account at bayonet connector height and structural strength under, how effectively to can reduce whole height, and can effectively solve sheet D melt subsides mode derive and have the not enough problem with damaging of structural strength, then need to be engaged in this journey dealer redesign effectively to be solved.
