  With the above configuration, a hole (cut) is required in the metal case, which is not preferable from the viewpoint of EMC (Electro-Magnetic Compatibility), and another structure that covers the hole (cut) is required. In order to fix the position of the shield plate, for example, a method of insert molding in a resin body may be considered. The problem with this method is that the cost increases due to complication of molding. Further, a method is conceivable in which the shield plate is formed into a barbed shape and press-fitted and fixed to the resin body. The problem with this method is that the degree of freedom of the product shape is limited.

  In view of the above, an object of the present invention is to provide a connector that allows good conduction between a metal case and a shield plate without providing a hole (cut) in the metal case, and that can fix the shield plate to the metal case satisfactorily. And

  The connector of the present invention includes a metal case and a contact assembly housed in the metal case.

  The contact assembly includes a resin body, a plurality of contacts fixed to the resin body, and a shield plate fixed to the resin body and blocking radio wave propagation between predetermined contacts. The first case is formed on the inner surface of the metal case. When the contact assembly is accommodated in the metal case, the shield plate is formed with a second fukurin that engages with the first fukurin and fixes the metal case and the contact assembly.

  According to the connector of the present invention, the metal case and the shield plate can be satisfactorily conducted without providing a hole (cut) in the metal case, and the shield plate can be satisfactorily fixed to the metal case.

  Hereinafter, embodiments of the present invention will be described in detail. Note that components having the same functions are given the same reference numerals, and redundant description is omitted.

  Hereinafter, a schematic configuration of the connector according to the first embodiment will be described with reference to FIG. FIG. 1 is an exploded perspective view of the connector 1 of the present embodiment. As shown in FIG. 1, the connector 1 of the present embodiment includes a metal case 11 and a contact assembly 12 housed in the metal case 11.

  Here, the connection direction of the connector 1 is defined as a front direction, and the pull-out direction of the connector 1 is defined as a rear direction. The vertical direction and the horizontal direction are defined based on the front direction and the rear direction. The metal case 11 is partially open in the front direction and the downward direction. On the left and right inner surfaces of the metal case 11, a pair of first fukurins 111 protruding inwardly of the case are formed one by one on each inner surface. The first fukurin 111 may be, for example, circular. Fukurin is a gentle projection formed by embossing and projecting a part of a metal plate without penetrating it, and is also called a dowel.

  Hereinafter, a schematic configuration of the contact assembly 12 will be described with reference to FIG. FIG. 2 is an exploded perspective view of the contact assembly 12 of the present embodiment. As shown in FIG. 2, the contact assembly 12 includes a resin body 121, a plurality of first contacts 122 fixed to the resin body 121, a plurality of second contacts 123 also fixed to the resin body, Also includes a shield plate 124 fixed to the resin body 121 and blocking radio wave propagation between the first and second contacts. The first contact 122 and the second contact 123 are paired up and down, and their numbers are equal.

  On the front surface of the resin body 121, holes 1211 corresponding to the number of the first and second contacts are provided in two rows vertically. Similarly, holes 1212 corresponding to the number of the first and second contacts are provided on the lower surface of the resin body 121 in two rows. The first and second contacts 122 and 123 are L-shaped metal pieces extending in the forward and downward directions. Notches are provided at front ends of the first and second contacts 122 and 123 in a forward direction to form a forked shape. The first contact 122 is formed one size smaller than the second contact 123. The first contacts 122 are arranged in a line in the left-right direction and fixed to the resin body 121. The second contacts 123 are arranged in a line in the left-right direction, respectively, behind and above the paired first contacts 122 so as to cover the paired first contacts 122, respectively. Fixed to 121. The front ends of the first and second contacts 122 and 123 are exposed and fixed in the holes 1211 on the front surface of the resin body 121. The male terminal (not shown) of the mating connector is inserted into the hole 1211 on the front surface of the resin body 121 and makes electrical contact with the front ends of the first and second contacts 122 and 123. The lower ends of the first and second contacts 122 and 123 extend downward through a hole 1212 in the lower surface of the resin body 121 and are fixed in such a manner as to project a predetermined length from the lower surface of the resin body 121. Is done. The lower ends of the first and second contacts 122 and 123 are connected to a cable (not shown) or the like.

  The shield plate 124 is a flat metal plate developed in the front-rear and left-right directions, and is fixed to the resin body 121 so as to be interposed between the first and second contacts 122 and 123 which are paired up and down. . As a result, radio wave propagation between the first contact 122 and the second contact 123 is blocked. The shield plate 124 has a pair of protruding portions 1241 extending upward from the left and right ends thereof. The protruding portions 1241 protrude from the left and right ends of the resin body 121 and are exposed outside the resin body 121. Each of the left and right protrusions 1241 is provided with an elliptical second fukurin 12411 that protrudes outward.

  Next, the positional relationship between the first fukurin 111 and the second fukurin 12411 will be described with reference to FIGS. FIG. 3 is a perspective view illustrating a positional relationship between the metal case 11 and the shield plate 124 according to the present embodiment. FIG. 4 is a perspective view showing a state where the hatch 112 of the metal case 11 of the present embodiment is opened. 3, all components other than the metal case 11 and the shield plate 124 are omitted. For convenience, the metal case 11 is shown as being transparent. When the contact assembly 12 is accommodated in the metal case 11, as shown in FIG. At the time of insertion, the second fuchlin 12411 contacts the first fuchlin 111 from the rear side and prevents the contact assembly 12 from being inserted into the metal case 11. By pushing the contact assembly 12 forward with sufficient force, the second fuchlin 12411 rides over the first fuchlin 111 and moves to the front of the first fuchlin 111 as shown in FIG. In this state, the curved surface on the front side of the first fukurin 111 and the curved surface on the back side of the second fukurin 12411 are engaged with each other, thereby preventing the contact assembly 12 from being displaced rearward with respect to the metal case 11. Since the first fukurin 111 and the second fukurin 12411 are both conductors, the first fukurin 111 and the second fukurin 12411 are engaged (contact) with each other, so that the shield plate 124 and the metal case 11 are in contact with each other. Can be conducted. Therefore, the first and second fukurins 111 and 12411 have both roles of positioning and shield grounding.

[Modification 1]
Hereinafter, with reference to FIG. 5, a description will be given of a connector of Modification 1 in which the second fukurin is configured differently. FIG. 5 is a right side view illustrating the positional relationship between the first and second fukurins of the first modification. In FIG. 5, the metal case 11a is shown as being transparent.

  As shown in FIG. 5, the connector 1a according to the present modification is characterized in that first two fukurins 111a and 111b are formed on the left and right inner side surfaces of a metal case, and are arranged in a line in the front-rear direction. . Other configurations such as the second fukurin 12411 are the same as those in the first embodiment.

  In the present modification, when the contact assembly 12 is inserted, the second fukurin 12411 comes into contact with the first fukurin 111b from the rear side to prevent the contact assembly 12 from being inserted into the metal case 11. By pushing the contact assembly 12 forward with sufficient force, the second fuchlin 12411 rides over the first fuchlin 111b and, as shown in FIG. 5, in front of the first fuchlin 111b and in the first fuchlin 111b. It moves rearward, that is, between the two first fuchlins 111a and 111b, and stabilizes. In this state, the curved surface on the front side of the first fukurin 111b and the curved surface on the rear side of the second fukurin 12411 are engaged with each other, thereby preventing the contact assembly 12 from being displaced rearward with respect to the metal case 11. At the same time, the curved surface on the rear side of the first fukurin 111a and the curved surface on the front side of the second fukurin 12411 are engaged to prevent the contact assembly 12 from being displaced forward with respect to the metal case 11. By providing two first fukurins in this way, the contact assembly 12 is fixed to the metal case 11 in two directions (front and rear directions), so that the contact assembly 12 is further stabilized.

  The connector 1a disclosed in the present modification can be generally considered to be a connector having N as an integer of 2 or more and having N pieces of the first fukurin on the left and right inner surfaces. In this case, the second fuclin is located between the N first fuclins and is stable. In other words, the N first fuclins are stable in a position surrounding the second fuclin. The N first and second fukurins can prevent the contact assembly 12 from being displaced in the N direction with respect to the case 11a.
