Description

Electrical connector with shielding plate

The present invention relates to an electrical connector having a shield.

As an electrical connector in which a shield plate made of a metal plate is attached to the outer peripheral surface of a substantially rectangular parallelepiped casing, the technique disclosed in Patent Document 1 is known. According to Patent Document 1, a shield plate attached to a casing has a side plate portion whose position faces the side wall surface of the casing extending in the longitudinal direction, and is bent toward the side plate portion at the end portion in the longitudinal direction of the casing. The position is a connecting portion that connects the opposing side plate portions to each other, and an end plate portion that is bent from the connecting portion toward the end wall surface of the casing and faces the end wall surface. The connecting portion and the end plate portion have an L-shaped cross section and complement each other. At the four corners of the upper surface of the casing, a convex portion facing upward is provided, and the convex portion protrudes from the side wall surface of the casing and from the end wall surface to form a locking portion for the shield plate. The upper edge of the end portion of the side plate portion in the longitudinal direction is locked to the protruding lower edge of the locking portion. When the shield plate is attached to the casing from above, the end portion of the side plate portion is temporarily elastically deformed to be separated from the side wall surface of the casing when the shield plate is attached to the casing, and the elastic deformation is released when the installation is completed, and the card is removed. The protruding lower edge of the stop is locked to prevent the shield from being detached upward.

However, in the shield plate of Patent Document 1, the connecting portion and the end plate portion cover the entire length of the end plate portion, and the L-shaped cross-section is complementarily fitted to each other as described above. Therefore, when the shield plate is attached, the end portion of the side plate portion is elastically deformed. The length of the wrist that is flexed is only a flat portion of the end portion of the side plate portion and is short. The end portion of the side plate portion has a short wrist length and is difficult to flex. Therefore, when the end portion of the side plate portion is elastically deformed to pass over the locking portion, the shield plate must be strongly pressed down. This action exerts a large local stress on the locking portion of the housing and also causes damage to the locking portion.

Further, since the end plate portion is bent and formed into a cross section in an L shape from the joint portion, the end plate portion is located outside the longitudinal direction of the casing with respect to the bent portion required for the bending process, thereby causing shielding in the same direction. The enlargement of the board leads to an increase in the size of the connector.

The present invention has been made in view of such circumstances, and an object thereof is to provide an electrical connector having a shield plate which does not cause a large stress when mounted on a casing and which does not become large.

In the electrical connector having the shield plate of the present invention, a housing for accommodating the housing recess of the target connector is formed to open upwardly in a substantially rectangular parallelepiped shape, and the terminal is held, and a shield plate made of a metal plate is attached to the housing. .

In the electrical connector, in the present invention, the shielding plate is made by moving the metal plate The punching process and the bending process are formed as one member, and the outer peripheral surface of the casing is attached to the outer peripheral surface of the casing so as to surround the receiving recessed portion, and has a flat side plate extending along a side wall surface of the casing extending in the longitudinal direction of the casing. a flat end plate portion along an end wall surface of the case in which the side wall surface is positioned in a direction perpendicular to the side wall, and a connection between the side plate portions at a position on an upper surface of the end portion of the case in the longitudinal direction The end plate portion is formed to be bent at an end portion of the side plate portion in the longitudinal direction, and the connecting portion is formed into a strip shape by forming a flat plate surface parallel to the upper surface of the casing, and the end plate portion is formed. The upper edge of the end plate portion is brought close to one side edge of the connecting portion, and a locking portion is formed at a lower edge portion of the side plate portion. When the shielding plate is attached to the outer peripheral portion of the casing from above, the locking is performed. The fitting is locked to the engaged portion of the housing.

In the present invention, the shield plate is fitted to the locked portion of the casing by the locking portion formed at the lower edge of the side plate portion, and the outer peripheral portion of the casing is attached from above. Therefore, in the casing, it is not necessary to form the locking projection for locking with the upper edge of the side plate portion from the side wall surface of the casing as in a conventional manner, so that when the shield plate is mounted, the side plate portion of the shield plate is installed. It does not bend and deform in order to pass over the above convex portion.

Even if it is assumed that there is a relative manufacturing dimensional error between the shield plate and the casing, the curved portion between the joint portion and the side plate portion and the lower end of the opposite side plate portion are elastically deformed to a certain degree of opening degree by the above-mentioned dimensional error portion, There is a large deflection in the conventional manner over the above-mentioned locking projection. Since the end plate portion and the connecting portion are separated by a gap, the reinforcing portion is reinforced by a curved portion between the connecting portion and the end plate portion in a conventional manner. In contrast, the flat connecting portion that is not accompanied by the curved portion is easily deflected by itself, and the entire length thereof contributes to the deflection of the side plate portion in the thickness direction of the plate. Further, the curved portion between the joint portion and the side plate portion is not in a shape resisting the direction of the deflection, and the width thereof is narrow, so that the side plate portion is easily deflected in the thickness direction of the plate. Therefore, when the shield plate is mounted, no large stress is generated in the locked portion of the casing, and damage of the engaged portion can be prevented.

In the end plate portion, since the upper edge of the end plate portion is close to one side edge of the connecting portion, the shield plate does not increase in size in the longitudinal direction of the casing, and the connector is not enlarged in the same direction.

In the present invention, the end plate portion is formed by bending the side plate portion at both end portions of the side plate portion, and has a substantially U-shaped planar shape together with the side plate portion, and has a free end at an intermediate position of the end wall surface of the casing.

In the present invention, the end plate portion is preferably located in a range corresponding to the joint portion in the longitudinal direction of the casing. By arranging the end plate portion in a range corresponding to the connection portion, the size of the shield plate in the longitudinal direction of the casing can be reduced, and the size of the connector can be reduced.

According to the present invention, as described above, the side plate portion, the end plate portion, and the connecting portion of the shield plate have a flat plate shape, and are not bent and deformed beyond the locking convex portion of the casing as in the prior art, so that the casing is easily attached. Install and lock the shield. Further, even if there is a relative manufacturing dimensional error between the shield plate and the casing, since the joint portion is separated from the end plate portion, the belt-shaped joint portion covers the entire length thereof to contribute to the deflection in the plate thickness direction of the flat side plate portion. The lower end of the side panel is easy for each other It is easy to open and easy to install on the housing. Therefore, when the shield plate is mounted, no large stress is generated in the locked portion of the casing, and damage of the locked portion can be prevented.

According to the invention, in the end plate portion, the upper edge of the end plate portion is close to one side edge of the connecting portion, so that the shield plate does not increase in size in the longitudinal direction of the casing, and the connector in the same direction does not increase in size. .

The two end plate portions 32 located at the respective end portions in the longitudinal direction cover the surfaces of the end wall surface 12A of the casing 10 on both sides of the groove portion 12A-1 in the short-side direction. That is, a gap having the same width as the groove portion 12A-1 is formed between the free ends extending in the vertical direction with respect to the two end plate portions 32. The end plate portion 32 has an upper edge of the end plate portion 32 and a side edge on the outer side in the longitudinal direction of the two side edges of the connecting portion 33 extending in the short side direction, with a slight gap therebetween. Close.

In the present embodiment, the end plate portion 32 is positioned within a range corresponding to the connecting portion 33 in the longitudinal direction. Therefore, this portion can achieve miniaturization of the shield plate 30 in the longitudinal direction described above, and further downsizing of the connector 1.

Next, the manufacturing procedure of the shield plate 30 will be described based on Fig. 2 . FIG. 2 is a perspective view of a plate-shaped material which is a semi-finished product in a state before the bending process of the shield plate obtained by punching and bending a metal plate. In Fig. 2, the portion corresponding to each portion of the shield plate 30 is displayed with the figure number of "'" in the figure number of each portion shown in Fig. 1. On the other hand, in the second drawing, the bending positions I to IV are displayed with a slight chain line at the bending position of the bending process of the plate material.

First, the metal plate material is punched out to obtain a plate-like material 30' having the shape shown in Fig. 2 . Next, the plate-like material 30' is bent at respective positions in the order of the bending lines I, II, III, and IV. In other words, first, the intermediate portion of the grounding leg portion 31C' in the short-side direction of the side plate portion 31' is bent at a right angle to the bending line I extending in the longitudinal direction of the side plate portion 31'. The grounding leg portion 31C of Fig. 1 is obtained. Then, the intermediate portion of the grounding wrist portion 31A' in the short-side direction is bent and bent by the bending line II extending in the longitudinal direction, whereby the grounding wrist portion 31A of Fig. 1 is obtained.

Further, the boundary portion between the end plate portion 32' and the side plate portion 31' in the longitudinal direction is bent at right angles to the bending line III extending in the short side direction, whereby the end plate portion 32 of Fig. 1 is obtained. And will be in the short side above The boundary portion between the connecting portion 33' and the side plate portion 31' is bent at right angles to the bending line IV extending in the longitudinal direction, whereby the connecting portion 33 of Fig. 1 is obtained. Thereby, the plate material 30' is bent in this manner, and the shield plate 30 shown in Fig. 1 is completed. In the present embodiment, the plate-like material 30' is bent at the respective positions in the order of the bending lines I, II, III, and IV, and the order is not essential, and may be replaced as necessary.

Next, the assembly of the connector 1 will be described based on Fig. 1 . First, the terminal 20 is press-fitted to the terminal holding portion 16 of the casing 10 from below and attached to the casing 10 to obtain the connector body 2. Next, as shown in Fig. 1, the shield plate 30 is placed above the connector body 2, and then the shield plate 30 is moved downward and brought into the connector body 2 from above (arrow in Fig. 1) by The connector 1 is completed by mounting the outer peripheral portion of the casing 10. When the shield plate 30 is attached, the grounding arm portion 31A of the shield plate 30 is housed in the housing groove portion 17 of the casing 10. The lower end edge of the end plate portion 32 of the shield plate 30 is brought into contact with the upper surface of the protruding portion 18 of the casing 10, and the neck portion 19A of the locked portion 19 of the casing 10 is embedded in the shield plate from below. In the groove-shaped locking portion 31B formed by the side plate portion 31 of the 30, the locking portion 31B and the locked portion 19 are fitted to each other. The side plate portion 31 is prevented from floating from the side wall surface 11A of the casing 10 by the projecting portion 19B of the plated portion 19 of the plate portion.

In the present embodiment, as described above, the locking portion 31B of the shield plate 30 is fitted into the locked portion 19 of the casing 10 to be locked. Therefore, in the casing 10, it is not necessary to form a locking projection for locking with the upper edge of the side plate portion from the side wall surface of the casing, so that the screen is required. When the shield is mounted, the side plate portion of the shield plate does not flex and deform in order to pass over the convex portion.

Even if it is assumed that there is a relative manufacturing dimensional error between the shield plate 30 and the casing 10, the curved portion between the joint portion 33 and the side plate portion 31 and the lower end of the side plate portion 31 are slightly supported by the above-mentioned dimensional error degree. The degree of opening is elastically deformed, and unlike the conventional method, there is a large deflection in order to pass over the locking projection of the casing. Since the end plate portion 32 connecting portion 33 is separated by a gap, it is similar to the conventional method in which the bent portion is reinforced by the bent portion between the connecting portion 33 and the end plate portion 32, and the flat portion is not accompanied by the curved portion. The body of the connecting portion 33 covers the entire length thereof and is easily deflected in the thickness direction of the plate. Further, the flat portion-like connecting portion 33 is formed, and the curved portion between the connecting portion 33 and the side plate portion 31 is formed to have a narrow width except for a shape that does not resist the deflection direction, so that the bending portion of the portion is easily opened. Also improved. As a result, the side plate portion 31 can be easily bent in the thickness direction of the plate, so that the shield plate 30 described above can be easily attached to the casing 10. Therefore, in the present embodiment, when the shield plate 30 is attached, no large stress is generated on the locked portion 19 of the casing 10, and damage of the locked portion 19 can be prevented.
