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.
