Description

  The present invention relates to a connector including a shield, and more particularly to a connector including a shield having a corner defined by a plate portion.

  Patent Document 1 describes a connector that includes a plurality of terminals, a housing that holds the terminals, and a shield that covers the housing. The shield of Patent Document 1 has an upper plate portion that covers a plurality of surfaces of the housing, a pair of side plate portions, and a rear plate portion, and the upper plate portion, the side plate portion, and the rear plate portion are one sheet. This conductive member is formed by bending.

JP 2001-85115 A

  As in Patent Document 1, when the conductive member is bent, a gap is generated at a corner defined by the upper plate portion, the side plate portion, and the rear plate portion. The gap generated in the corner promotes the diffusion of radiation noise, and deteriorates the EMI (Electromagnetic Interface) countermeasure performance of the connector.

  An object of this invention is to provide the connector provided with the shield whose EMI countermeasure performance is higher than before.

  The first connector includes a contact, a housing that holds the contact, and a shell that covers at least a portion of the housing. The shell includes a first plate portion and a second plate portion that are integrally bent. It has a 3rd board part and a cover part, and the cover part is arrange | positioned so that the corner | angular part prescribed | regulated by a 1st board part, a 2nd board part, and a 3rd board part may be covered. Therefore, it is possible to reduce the diffusion of radiation noise from the corners and improve the shielding performance as compared with the conventional case.

  The second connector is a first connector in which the second plate portion and the third plate portion extend from the first plate portion, and the shell extends from the second plate portion to the third plate. A fourth plate portion extending so as to cover at least a part of the portion is further provided, and the cover portion extends from the fourth plate portion.

  A 3rd connector is a 2nd connector, and a cover part has a 1st site | part and a 2nd site | part, and a 1st site | part is a 3rd board from the side edge part of a 4th board part. The second portion extends along the portion toward the second plate portion, and the second portion extends from the second plate portion side end portion of the first portion into the corner portion.

  In the fourth connector, the cover has a notch between the first part and the second part. Therefore, the radius of the bent part between the first part and the second part is made small so that the cover is square. It can be easily stored in the club.

  In the present invention, the shield performance can be improved as compared with the conventional one by providing the cover at the corner.

  As shown in the perspective view of FIG. 1 and the exploded perspective view of FIG. 2, the connector 1 of this embodiment includes a housing 10, a shell 11, and two contacts 12. In addition, the left-right direction, the up-down direction, and the front-back direction are defined for convenience of explanation.

  As shown in FIG. 2, the housing 10 is formed in a rectangular parallelepiped shape with an insulating material, and has a slot 20 opened in a rectangular shape toward the front. The slot 20 is formed so that a mating connector can be fitted therein. The housing 10 has an upper surface 22 facing upward, a lower surface 23 facing downward, a right side surface 24a facing right, a left side surface 24b facing left, and a rear surface 25 facing rear. . Further, the housing 10 has two slits 21 that penetrate the right side surface 24a and the left side surface 24b from the outside in the left-right direction into the slot 20, respectively.

  As shown in FIG. 2, the two contacts 12 are each formed in an L shape. The contact 12 is held in the housing 10 by being inserted into the slot 20 from the outside of the rear surface 25 of the housing 10. The contact 12 has a straight line portion 12a extending in the insertion direction and another straight line portion 12b extending downward from the straight line portion 12a and formed so as to be connectable to the substrate. The terminal portions of the other straight portions 12b protrude below the lower surface 23 of the housing 10 and are connected to the substrate (not shown).

  As shown in the exploded perspective view of FIG. 2 and the perspective view of FIG. 3, the shell 11 includes an upper plate portion 30, a right plate portion 31a, a left plate portion 31b, a rear plate portion 32, a right bent portion 33a, and a left bent portion 33b. And a right cover part 34a, a left cover part 34b, four soldering parts 35, and two claw parts 36. The shell 11 is formed by bending a single conductive plate material.

  The upper plate portion 30 has a rectangular shape that extends in the left-right direction and the front-rear direction, and extends so as to cover the upper surface 22 of the housing 10.

  The right plate portion 31a and the left plate portion 31b extend downward from the right edge portion and the left edge portion of the upper plate portion 30, respectively, and are suitable for covering the right side surface 24a and the left side surface 24b of the housing 10. Has a rectangular shape extending in the front-rear direction and the up-down direction.

  The rear plate portion 32 extends downward from the rear edge of the upper plate portion 30 and has a rectangular shape that extends in the vertical direction and the horizontal direction so as to cover the rear surface 25 of the housing 10.

  The right bent portion 33a and the left bent portion 33b extend forward from the right edge portion and the left edge portion of the rear plate portion 32, respectively, near the rear ends of the right plate portion 31a and the left plate portion 31b. It extends so as to cover a part. The right bent portion 33a is formed between the right plate portion 31a and the rear plate portion 32 and covers a gap extending in the vertical direction. The left bent portion 33b is formed between the left plate portion 31b and the rear plate portion 32 and covers a gap extending in the vertical direction.

  As shown in FIGS. 3 and 4, the shell 11 includes a right corner portion 37 a surrounded by the upper plate portion 30, the rear plate portion 32, and the right plate portion 31 a, the upper plate portion 30, the rear plate portion 32, and the left plate portion. A left corner 37b surrounded by 31b is defined. The connection portion between the upper plate portion 30 and the right plate portion 31a, the connection portion between the upper plate portion and the left plate portion 31b, and the connection portion between the upper plate portion 30 and the rear plate portion 32 are bent gently. Since the margin is provided, recesses are formed in the right corner portion 37a and the left corner portion 37b, and a gap 38a and a gap 38b are formed in the right corner portion 37a and the left corner portion 37b.

  As shown in FIG. 3, the right cover portion 34 a and the left cover portion 34 b are disposed at the side edges of the right bent portion 33 a and the left bent portion 33 b, that is, at the upper end portions close to the upper plate portion 30, respectively. As shown in FIG. 4, the right cover portion 34 a has an L shape that includes a first portion 41 and a second portion 42. The first portion 41 is connected to the right bent portion 33a at the front end and extends in the front-rear direction. The second portion 42 extends from the rear end of the first portion 41 toward the right corner portion 37a and covers the gap 38a. The left cover part 34b having a mirror image-like shape with the right cover part 34a covers the gap 38b in the left corner part 37b.

  By providing the right cover portion 34a and the left cover portion 34b, the gap 38a and the gap 38b formed in the right corner portion 37a and the left corner portion 37b can be covered, and the EMI countermeasure performance can be improved as compared with the conventional case. Furthermore, since the right cover part 34a and the left cover part 34b can be formed integrally with the other components of the shell 11 by a series of pressing processes, they can be easily manufactured without increasing the number of parts. Furthermore, by providing the right cover portion 34a and the left cover portion 34b, it is possible to prevent dust and dirt from entering the shell 11 from the gap 38a and the gap 38b.
