Description




FIELD OF THE INVENTION




The present invention relates to an improved connector protection cover structure and, more particularly, to an improved connector protection cover structure, which can protect a connector, and can be conveniently connected with or separated from the connector.




BACKGROUND OF THE INVENTION




Nowadays, along with higher and higher use frequency of computers by common people, the requirements of processing, execution, contents, and equipments of computers become more and more stringent. In order to let computers be more diversified, products related to computers like mice, keyboards, digital still cameras, scanners, modems, and printers have been continually developed. All the above products utilize connectors to connect with computers. Therefore, in order to let connectors have good quality, connector protection covers have been provided to protect the connectors.




As shown in

FIGS. 1 and 2

, a protection cover


11


integrally formed of several plastic by molding ejection and a corresponding connector


12


are connected together to protect terminals


121


in the connector


12


and avoid deformation of the terminals due to transportation or stacking, hence increasing the yield of the connector


12


.




However, the above connector protection cover


11


has at least the following drawbacks in use.




(1) Because the terminals


121


of the connector


12


are separately arranged and form several blocks, the protection cover


11


needs to correspond to the terminals


121


of the blocks. Therefore, it is necessary to increase greatly the number of the protection covers


11


.




(2) The connector


12


and the protection cover


11


are U-shaped and inversely U-shaped, respectively. After they are connected together, there is no gap. Therefore, there is difficulty in separating the connected connector


12


and protection cover


11


. It is necessary to take advantage of a professional tool (e.g., a screwdriver).




(3) When the professional tool is inserted between the connector


12


and the protection cover


11


, the wall edge of the connector may easily be damaged.




(4) Because the inversely U-shaped protection cover


11


is inserted into the inner edge of the U-shaped connector


12


, the terminals


121


may easily deform.




(5) When the inversely U-shaped protection cover


11


is formed by molding ejection, because there is no buffer region, it may easily tilt and deform, hence lowering the yield.




(6) Decrease of the yield not only wastes the material, but also increases the production cost.




Accordingly, the above conventional connector protection cover has inconvenience and drawbacks in practical installation and use. The present invention aims to resolve the problems in the prior art.




SUMMARY OF THE INVENTION




The primary object of the present invention is to provide an improved connector protection cover structure to effectively increase the yield in manufacturing the protection cover integrally formed of plastic by molding ejection, thereby saving the material and lowering the production cost. Moreover, the strength of the top face of the protection cover can be reinforced to facilitate stacking of the connectors during transportation.




Another object of the present invention is to provide an improved connector protection cover structure, whereby a connector can be separated from the protection cover without any professional tool (e.g., a screwdriver). Therefore, scrapes on the surface of the connector can be avoided.




To achieve the above objects, the present invention provides an improved connector protection cover structure, wherein an elastic locking structure is disposed at two sides of the protection cover. An abutting portions having a ‘<’-shaped part and a ‘>’-shaped part is formed on the locking structure to abut against the outer edge wall of the connector so that the protection cover and the connector can be firmly connected together.




The present invention also provides an improved connector protection cover structure, wherein reinforcement portions are formed at the inner top face and two inner sides of the protection cover to effective increase the strength of the top face of the protection cover, hence preventing the inner top face of the protection cover from crushing the terminals due to stacking of the connectors.




The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing, in which:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




As shown in

FIGS. 3 and 4

, the present invention relates to an improved connector protection cover structure and, more particularly, to an improved connector protection cover structure, which can be conveniently connected with or separated from a connector to protect the connector. The present invention is a protection cover


20


integrally formed of plastic by molding ejection. The protection cover


20


is connected with a corresponding connector


30


to protect terminals


31


in the connector


30


and avoid deformation of the terminals due to transportation or stacking, hence increasing the yield of the connector


30


. The above structure is the same as the prior art and thus will not be further described.




As shown in

FIGS. 3

,


4


, and


5


, the protection cover


20


is inversely U-shaped to correspond to the U-shaped connector


30


for connection.




A projective piece


23


and an elastic locking structure


21


are disposed at the top face and two sides of the protection cover


20


, respectively. The projective piece


23


is used to separate the protection cover


20


from the connector


30


. The locking structure


21


is an elastic sheet body. An abutting portion


211


is formed on the locking structure


21


. The abutting structure


211


has a ‘<’-shaped part and a ‘>’-shaped part.




The abutting portion


211


can abut against the outside of the U-shaped connector with its only elasticity (as shown in

FIG. 5

) so that the protection cover


20


and the connector


30


can be firmly connected together.




Moreover, because the protection cover


20


is integrally formed of plastic by molding ejection, a buffer region will be formed when forming the abutting portion


211


, hence avoiding generation of tilt and deformation. Therefore, the yield can be increased to save the material and lower the production cost.




Besides, reinforcement portions


22


are formed at the inner top face and the link positions at two inner sides of the protection cover


20


. The reinforcement portions


22


can effectively enhance the strength of the top face of the protection cover


20


to prevent the inner top face of the protection cover


20


from crushing the terminals


31


due to stacking of the connector


30


.




As shown in

FIG. 6

, the projective piece in

FIG. 3

can be saved. When the protection cover


20


and the connector


30


are separated, two sides of the protection cover


20


can be exploited for direct extraction.




As shown in

FIG. 7

, the projective piece


23


in

FIG. 3

can be several projective ears to facilitate separation of the protection cover


20


from the connector


30


.




To sum up, the improved connector protection cover of the present invention has the following advantages.




(1) The elastic locking structure


21


formed at two sides of the protection cover


20


abuts against the U-shaped connector


30


so that the protection cover


20


and the connector


30


can be firmly connected together.




(2) The abutting portion


211


has a ‘<’-shaped part and a ‘>’-shaped part to facilitate separation of the protection cover


20


from the connector


30


. Moreover, scrapes on the surface of the connector


30


can be avoided.




(3) A buffer region is formed when the abutting portion


211


is formed of plastic by molding ejection, hence avoiding tilt and deformation. The yield can thus be increased. Moreover, the material can be saved and the production cost can be lowered.




(4) The reinforcement portions


22


are formed at the inner top face and the link positions at two inner sides of the protection cover


20


to effectively enhance the strength of the top face of the protection cover


20


, hence preventing the inner top face of the protection cover


20


from crushing the terminals


31


due to stacking of the connector


30


.




Using the present inventive construction, it is not necessary to use a professional tool like a screwdriver to separate the protection cover from the connector. Scrapes on the surface of the connector can also be avoided. Further, the reinforcement portions are formed at the inner top face at two inner sides of the protection cover to prevent the protection cover from crushing terminals in the connector due to stacking of the connectors during transportation.




Although the present invention has been described with reference to the preferred embodiment thereof, it will be understood that the invention is not limited to the details thereof. Various substitutions and modifications have been suggested in the foregoing description, and other will occur to those of ordinary skill in the art. Therefore, all such substitutions and modifications are intended to be embraced within the scope of the invention as defined in the appended claims.
