Abstract
An anti-reverse-insertion structure of a micro connector shell comprises a plug shell and a socket shell, wherein the same side of the width direction of the butt joint end of the plug shell is provided with a matched convex circular arc which is in a continuous round angle shape; the corresponding part of the socket shell is provided with a corresponding convex circular arc, the top of the convex circular arc is provided with a straight line section, and the other parts of the butt joint end of the plug and the socket shell except the convex circular arc are provided with a straight line section and a transition fillet. The utility model has the advantages of small occupied space and favorable development of products to miniaturization. The micro-electric connector is suitable for the micro-electric connector with the contact pitch not greater than 0.635 mm.
Description
One, technical field
The utility model relates to a kind of micro connector shell, belongs to technical field of electric connectors.
Two, background technology
Electric connector is divided into plug and socket, instead inserts for preventing plugs and sockets, and the connector shell structure generally has two kinds: a kind of is to adopt the counnter attack of angled oblique angle to insert, as shown in Figure 1.Another kind is that the big or small fillet counnter attack on the outer shell is inserted, as shown in Figure 2.But this dual mode all has certain limitation, and mode 1 is to prevent reciprocal plugging together by the oblique angle, and Angular Dimension has taken bigger space undoubtedly; Process angled inclined-plane in addition, size be cannot say for sure to demonstrate,prove, and micro connector is harsh more to the required precision of plug and socket fit dimension, has increased the difficulty of processing with this structure, and can't guarantee the merging precision of plug and socket.Mode 2 is subjected to the influence of Milling Process tool dimension, and the fillet size can not be done very for a short time, and this structure can only be used for the bigger product of profile.Therefore these two kinds of shell mechanisms all have corresponding limitation in the microminiaturization that realizes the connector product.For realizing the microminiaturization development of connector product, need a kind of shell mechanism that is applicable to microminiaturized product of exploitation, solve the counnter attack of little interval connector product casing and insert problem.
Three, summary of the invention
The purpose of this utility model provides a kind of, solves the counnter attack of micro connector product and inserts problem.
The utility model micro connector shell protective design to avoid insterting by mistake is made up of plug body and jack housing, and Width the same side of plug body butt end is provided with the protruding arc of cooperation, and this circular arc is continuous rounded shapes; The jack housing corresponding site is provided with corresponding protruding circular arc, and this projection circular arc top is a straightway.
Other position that protruding circular arc is removed in plug, jack housing butt end is set to straightway and knuckle.
When plugging together, the straightway that jack housing increases can get out of the way the circular arc at plug place, realizes plugging together smoothly, oppositely then can not plug together, and has played the effect that counnter attack is inserted; The quality of fit of shell guarantees by the straight line position of butt end.Because important cooperation is straightway, precision is easier to guarantee that handling ease realizes.In addition, the utility model adopts the circular arc in shell Width projection to come counnter attack to insert, as long as a very little crown height size (greater than the maximum fit clearance of shell) can realize, therefore the utlity model has and take up room for a short time, be beneficial to the advantage of product to the microminiaturization development.Be applicable to that the contact spacing is not more than the miniature electric connector of 0.635mm.
Four, description of drawings
Fig. 1 is the protective design to avoid insterting by mistake schematic diagram that the oblique angle is arranged in the prior art
Fig. 2 is with big or small fillet protective design to avoid insterting by mistake schematic diagram in the prior art
Fig. 3 is a plug body structural representation of the present utility model
Fig. 4 is a jack housing structural representation of the present utility model
Among the figure: 1-plug body, 2-plug projection circular arc, 3-jack housing, 4-socket bumps circular arc, 5-straightway.
Five, embodiment
As shown in Figure 3, Figure 4, the utility model micro connector shell protective design to avoid insterting by mistake is made up of plug body 1 and jack housing 3, and Width the same side of plug body 1 butt end is provided with the protruding circular arc 2 of cooperation, and this circular arc is continuous rounded shapes; Jack housing 3 corresponding sites are provided with corresponding protruding circular arc 4, this projection circular arc top is provided with straightway 5, other position of plug, jack housing butt end is set to guarantee the straightway and the knuckle of quality of fit, the protruding circular arc 2,4 of Width can realize that the counnter attack of micro connector shell is slotting like this, and the cooperation of straightway can guarantee the quality of fit of plug, jack housing.
