Description

Cable connector and connector assembly thereof

[ technical field ] A method for producing a semiconductor device

The present invention relates to a cable connector and a connector assembly thereof, and more particularly to a cable connector and a connector assembly thereof capable of preventing an oblique insertion.

[ background of the invention ]

A conventional cable connector is used to mate with a mating connector, and the cable connector includes a mating circuit board, a cable and an insulating body. The front end of the butt joint circuit board protrudes forwards to form an insulation body for being inserted into the butt joint connector, the flat cable is welded at the rear end of the butt joint circuit board, and the insulation body is formed on the butt joint circuit board and the cable in an cladding mode. The butting connector comprises a butting main body, an upper row of conductive terminals and a lower row of conductive terminals which are inserted in the butting main body, and a butting iron shell which is coated outside the butting main body, wherein the butting iron shell comprises two side plates and a top plate which is connected with the two side plates, and an opening of the butting iron shell is positioned behind the butting main body.

The butt joint process of the cable connector and the butting connector comprises the following steps: the butt-joint circuit board of the cable connector is inserted into the opening of the butt-joint iron shell of the butt-joint connector forwards until the butt-joint circuit board is clamped between the conductive terminals, so that the front end of the butt-joint circuit board is electrically connected with the conductive terminals, and the butt joint of the cable connector and the butt-joint connector is realized.

However, since the front end of the insulating body is provided with only the mating circuit board, a gap between the mating circuit board and the opening of the mating iron case is large and the guide device is not provided. When the butt circuit board is inserted forward into the opening of the butt iron shell, the butt circuit board is easily inserted into the opening of the butt iron shell in an inclined manner due to lack of a guiding device and inaccurate alignment, which causes scratches on the butt circuit board and the butt connector, and further affects the butt performance of the cable connector and the butt connector.

Therefore, there is a need for an improved cable connector to overcome the above problems.

(1) since the metal guide 5 is added to shield the abutting portion 12 and the inserting portion 31 and guide the abutting connector 100 to accurately abut against the abutting portion 12 and the inserting portion 31 to prevent oblique insertion, the first guide tab 514 and the second guide tab 523 guide the abutting end 71 of the shielding shell 7 to be inserted backwards, the first limiting groove 511 limits the movement of the abutting end 71 in the Y-axis direction, the second limiting groove 521 limits the movement of the abutting end 71 in the Z-axis direction, thereby ensuring accurate abutting of the cable connector 100 and the abutting connector 200, effectively avoiding the scratch and damage of the cable connector 100 and the abutting connector 200 due to incorrect alignment, enhancing the abutting performance of the cable connector 100 and the abutting connector 200, and the upper end of the two side plates 51 is integrally connected with the top plate 52, the lower ends of the two side plates 51 are disconnected from each other, so that the structure of the metal guide 5 is simplified to facilitate the molding of the metal guide 5, and the cable connector 100 better meets the requirements of users.

(2) The two side plates 51 and the top plate 52 simultaneously shield the butting portion 12 and the inserting portion 31, the inserting portion 31 is effectively prevented from being scratched and damaged by an external environment, the third limiting groove 512 is communicated with the fourth limiting groove 522 and is used for accommodating the electric connecting seat 6, the third limiting groove 512 limits the movement of the electric connecting seat 6 in the Y-axis direction, the fourth limiting groove 522 limits the movement of the electric connecting seat 6 in the Z-axis direction, and the electric connecting seat 6 and the inserting portion 31 can be guaranteed to be reliably electrically butted all the time.

(3) When the cable connector 100 is mated with the mating connector 200, the bottom surface of the side plate 51 is higher than the bottom surface of the mating portion 12, so that the bottom surface of the side plate 51 is spaced from the top surface of the printed circuit board 8, thereby preventing the bottom surface of the side plate 51 from contacting the conductive circuit on the top surface of the printed circuit board 8 to cause short circuit, and further ensuring the mating performance of the cable connector 100 and the mating connector 200.

(4) The notch 528 exposes the locking portion 21, so that a user can observe the locking condition of the locking portion 21 and the locking hole 733 through the notch 528.

The above detailed description is only for the purpose of illustrating the preferred embodiments of the present invention, and not for the purpose of limiting the scope of the present invention, therefore, all the equivalent technical changes applying the present specification and the drawings are included in the scope of the present invention.
