Title: Embedded short leaf-spring-equipped crystal head and extractor thereof

Description:
BACKGROUND OF THE INVENTION 
     1. Technical Field 
     The present invention relates to the field of internet cable crystal heads and more particularly to an embedded short leaf-spring-equipped crystal head and an extractor thereof. 
     2. Description of Related Art 
     An internet cable crystal head, an important peripheral apparatus dedicated to network connection, is a connector which is plugged in a fixed direction, capable of preventing spontaneous disconnection, applicable to network-based communication, and for use in connecting with a network card port, a hub, a switchboard, or a phone. A leaf spring is disposed above a conventional crystal head. The crystal head is inserted into a base and thus fastened to the base by the leaf spring. The length of the leaf spring is configured to be larger than the depth of a base slot. It is easy for a user to pull out the crystal head by pressing the leaf spring. 
     However, a conventional crystal head has drawbacks as follows: 
     1. the leaf spring is exposed from the base and thus likely to be hit by any external object; as a result, the leaf spring is likely to sever and deform; and 
     2. the conventional crystal head in operation may be pulled out by any unauthorized person, thereby leading to data loss. 
     BRIEF SUMMARY OF THE INVENTION 
     In view of the aforesaid drawbacks of the prior art, it is an objective of the present invention to provide an embedded short leaf-spring-equipped crystal head and an extractor, characterized advantageously in that the embedded short leaf-spring-equipped crystal head cannot be pulled out by any unauthorized person, thereby preventing data loss. 
     In order to achieve the above and other objectives, the present invention provides an embedded short leaf-spring-equipped crystal head, comprising: a crystal head body insertable into a base slot of a base and a leaf spring disposed above the crystal head body to fasten the crystal head body to the base, characterized in that a length of the leaf spring is less than or equal to a length of the base slot. 
     A protrusion portion is disposed at an end portion of the leaf spring. 
     In order to achieve the above and other objectives, the present invention further provides an embedded short leaf-spring-equipped crystal head extractor, comprising a handle with a front end having an extraction bump corresponding in position to the leaf spring. 
     The front end of the extraction bump is of a smaller thickness than the rear end of the extraction bump. 
     The advantages of the present invention are described below. The length of the leaf spring is configured to be less than or equal to the length of the base slot. After the crystal head body has been inserted into the base slot of the base, the leaf spring is fully disposed inside the base and thus is not exposed; hence, not only does the space utilization rate of the crystal head body increase, but the positioning of the crystal head body is not compromised as a result of damage otherwise caused to the leaf spring. The crystal head body can only be taken out with a dedicated extractor, so as to prevent any unauthorized person from taking out the crystal head body, thereby enhancing data security.

     DETAILED DESCRIPTION OF THE INVENTION 
     Referring to  FIGS. 1-5 , the present invention relates to an embedded short leaf-spring-equipped crystal head which comprises: a crystal head body  1  insertable into a base slot  21  of a base  2 ; and a leaf spring  11  disposed above the crystal head body  1  to fasten the crystal head body  1  to the base  2 . The length of the leaf spring  11  is less than or equal to the length of the base slot  21 . 
     Compared with the prior art, the present invention is characterized in that the length of the leaf spring  11  is configured to be less than or equal to the length of the base slot  21 . After the crystal head body  1  has been inserted into the base slot  21  of the base  2 , the leaf spring  11  is fully disposed inside the base  2  and thus is not exposed; hence, not only does the space utilization rate of the crystal head body  1  increase, but the positioning of the crystal head body  1  is not compromised as a result of damage otherwise caused to the leaf spring  11 . A protrusion portion  111  is disposed at the end portion of the leaf spring  11 . The leaf spring  11  extends upward obliquely in a direction opposite to a direction of the head body  1  being inserted into the base slot  21 , and a top surface of the protrusion portion  111  is in contact with an inner surface of the base slot  21 . 
     Since the protrusion portion  111  is disposed at the end portion of the leaf spring  11 , the crystal head body  1  is fastened to the base slot  21  to thereby prevent disconnection of the crystal head body  1 . 
     Referring to  FIG. 3 , an embedded short leaf-spring-equipped crystal head extractor comprises a handle  31 . An extraction bump  32  is disposed at the front end of the handle  31  and corresponds in position to the leaf spring  11 . The front end of the extraction bump  32  is of a smaller thickness than the rear end of the extraction bump  32 . 
     Unlike its conventional counterparts, the crystal head body  1  of the present invention can only be taken out with a dedicated extractor, so as to prevent any unauthorized person from taking out the crystal head body  1 , thereby enhancing data security. 
     Since the front end of the extraction bump  32  is of a smaller thickness than the rear end of the extraction bump  32 , a user takes the crystal head body  1  out of the base  2  by inserting the extraction bump  32  into the base slot  21  of the base  2  to press the leaf spring  11  with the extraction bump  32 . 
     The present invention is illustrated with a specific embodiment and further described below. 
     After the crystal head body  1  has been inserted into the base slot  21  of the base  2 , the leaf spring  11  is fully disposed inside the base  2 , and the protrusion portion  111  at one end of the leaf spring  11  fastens the crystal head body  1  to the base slot  21 , as shown in  FIG. 4 . 
     To take out the crystal head body  1 , the user inserts the extraction bump  32  of the extractor into the base slot  21  from above the leaf spring  11  to thereby press the leaf spring  11 , as shown in  FIG. 5 . 
     Although the present invention is disclosed above by preferred embodiments, the embodiments are not restrictive of the present invention. Any persons skilled in the art can make various changes and modifications to the embodiments without departing from the spirit the present invention. Accordingly, the legal protection for the present invention should be defined by the appended claims.
