DETAILED DESCRIPTION OF EMBODIMENTS

(10) This and other aspects of the present disclosure will now be described in more detail, with reference to the appended drawings showing a currently preferred embodiment of the invention.

(11) As shown in FIGS. 1-9, an embodiment of the present disclosure provides a hard disk data interface pitch converter which comprising a converting part 1. The converting part 1 comprises converting terminals 5 and contact terminals 6. The contact terminals 6 comprise a plurality of metallic conductors which are independent from one another. The converting terminals 5 comprise a plurality of metallic conductors, and are arranged in such a manner that the plurality of metallic conductors have a relatively large interval at one end and a relatively small interval at the other end for realizing pitch conversion. In this way, a large pitch is converted into a small pitch, so that the cost of product is reduced. The end of the converting terminals 5 with a large interval between metallic conductors is connected in a one-to-one manner to an end of the metallic conductors in the contact terminals 6.

(12) The hard disk data interface pitch converter further comprises a short connection part 2. The short connection part 2 connects any two or more non-adjacent metallic conductors in the contact terminals 6 through metallic conductors. It is noted that, the short connection part 2 are not only used for connecting non-adjacent metallic conductors, but also for connecting two neighboring conductors. However, if it is necessary to connect two neighboring metallic conductors, there is no need for the short connection part 2, since two neighboring metallic conductors in the converting terminals 5 can be directly connected with each other. This also leads to no occupation in volume. Therefore, in the present disclosure, the short connection part 2 mainly functions to connect non-adjacent metallic conductors.

(13) The hard disk data interface pitch converter further comprises a base 3. The base 3 is provided with a channel 7 for accommodating the contact terminals 6 and a slot for fixing the short connection part 2.

(14) The hard disk data interface pitch converter further comprises a cover body 4, which cooperates with the base 3 for protecting the converting part 1 and the short connection part 2.

(15) An extension part 9 is formed by digging each of the metallic conductors of the contact terminals 6. The extension part 9 exactly shields a gap between contact terminals 6 and the channel 7. In the prior art, an additional blocking piece is provided to at the gap. In this case, not only a piece (i.e., the blocking piece) is added, but also a set of procedure is added, which increases the production cost. In the present disclosure, the extension part 9 is formed from the metallic conductors themselves by digging. The extension part 9 functions to prevent dust, foreign objects, and adhesives. Further, the gap is shielded once the converting part 1 is assembled, which not only makes full use of the raw material, but also saves a procedure.

(16) In another embodiment of the present disclosure, the base 3 is provided with raised blocks 10 to be hot melt for fixing the converting terminals 5. The raised blocks 10 are arranged alternately between the converting terminals 5. The raised blocks 10 by themselves are made from a hot melting type plastic. When the raised blocks are hot pressed, they soften and flow to a surface of the converting terminals 5. After cooling, the raised blocks firmly fix the converting terminals 5 to the base 3. The raised blocks 10 can prevent metallic conductors in the converting terminals 5 from being short circuited.

(17) In a further embodiment of the present disclosure, the raised blocks 10 are provided with a first guiding angle 11 at the top, and have a height which is 0.5-2 times larger than an interval between the raised blocks 10. The first guiding angle 11 functions in such a manner that when the raised blocks 10 are melt by hot pressing, the melt plastic adhesive uniformly spreads to both sides and covers the surface of metallic conductors of the converting terminals 5. A ratio between the height of the raised blocks 10 and the interval between the raised blocks 10 is controlled precisely, so that an adhesive content in the raised portion of the raised blocks 10 is defined. In this way, it is ensured that the amount of adhesives from the melt raised blocks can exactly cover and fix the metallic conductors, without adhesive overflowing and adhesive breaking.

(18) In a further embodiment of the present disclosure, preferably, the converting terminals 5 and the contact terminals 6 can be formed into an integral part (as shown in FIG. 2) or can be connected by soldering, i.e., of a split type construction (as shown in FIG. 9).

(19) In a further embodiment of the present disclosure, the base 3 is provided with stop holes 12 at both ends, and the cover body 4 is provided with stop columns 13 corresponding to the stop holes 12.

(20) In a further embodiment of the present disclosure, each of the stop columns 13 is provided with a stop block 14 at the bottom and a second guiding angle 15 at the top. The stop columns 13 have a cross section identical with that of the stop holes 12. The second guiding angle 15 functions to provide guiding during assembling, so that the top of the stop columns 13 easily enter the stop holes 12 and then are stopped by the stop block 14.

(21) In a further embodiment of the present disclosure, the cover body is provided with a first hook 16 at one side and a first groove 17 at the other side, the base is provided with a second groove 18 at one side which cooperates with the first hook 16 and a second hook 19 on the other side which cooperates with the first groove 17. The first hook 16 and the stop block 14 are arranged at a same side. In this design, during assembling, the first groove 17 and the second hook 19 snap-fit firstly, the cover body 4 and the base 3 form an inclined angle which helps the stop columns 13 to be guided into the stop holes 12, and the first hook 16 and the second groove 18 snap-fit finally. This assembling manner is more fast than a manner in which the cover body 4 and the base 3 snap-fit in a straight up and down way. Besides, in this assembling manner, a small force is asserted on the hook, so that small and precise parts like hooks are less prone to damage. Therefore, this assembling manner not only increases the efficiency of assembling, but also decreases the defective percentage of the final product.

(22) In a further embodiment of the present disclosure, the cover body is provided with a check block 20 for protecting the converting terminals. The check block 20 mainly functions to prevent dust and foreign objects.

(23) In a further embodiment of the present disclosure, the cover body is provided with flat cable holes 21 through which flat cables pass.

(24) The hard disk data interface pitch converter are produced by steps of stamping forming a raw material, injection molding, electroplating, assembling, inspection, packaging, and shipment.

(25) The above are merely embodiments of the present disclosure. It should be appreciated that, a person skilled in the art may make further improvements and modifications without departing from the principle of the present disclosure, and these improvements and modifications shall also fall within the scope of the present disclosure.
