Connector and connector device

This invention relates to connectors and connector devices. In particular, the present invention relates to a connector for plugs and sockets for electrical connection between two printed wiring boards, and a connector device comprising a plug and a socket.

In the past, connector devices for directly electrically connecting two printed wiring boards without a cable have been known. The connector device is composed of a plug that is mounted on one printed circuit board and a socket that is mounted on the other printed circuit board. By fitting the plug to the socket, the brushing lines of the two printed circuit boards are electrically connected to each other ( For example, refer to Patent Document 1).

In recent years, with the small size and thinness of the connector, the strength of the connector is lowered. This is because the connector housing is formed of a resin material, and it is difficult to maintain the required strength because of its small size or thinning. Therefore, there is a possibility that the stress generated during the insertion and removal of the connector cannot be resisted, resulting in destruction of the casing.

Fig. 19(a) is a view showing a state in which the connector is removed. Connecting two printed lines by fitting the plug 10 and the socket 20 In the state of the road plates 30 and 40, the end portion of one of the printed wiring boards 30 is lifted by the fingers 50, whereby the plug 10 is detached from the socket 20 mounted on the other printed wiring board 40. However, in this operation, in the 19th (b)th drawing and the 19th (c) drawing of the enlarged view of the A part, the symbol B indicates that there is a possibility that stress concentration causes damage to the casing. This portion is formed of a resin material only in a thin wall, and is weaker than other portions, and is incapable of withstanding an external force applied to the plucking operation, and is liable to cause breakage or the like. For this reason, the periphery is reinforced with a reinforced metal member (for example, refer to Patent Document 1).

The plug connector disclosed in Patent Document 1 is a metal plug member provided with a reinforcing member function in the first plug wall portion. The metal plug member has a pair of third plug plate portions embedded in the second plug wall portion, and strengthens the joint between the first plug wall portion and the second plug wall portion.

Moreover, the receptacle connector disclosed in Patent Document 1 is provided with a metal socket member having a function of a reinforcing member in the first socket wall portion. The metal socket member has a pair of sixth socket plate portions that are embedded in the second socket wall portion, and strengthens the connection between the first socket wall portion and the second socket wall portion.

[First Embodiment]

Fig. 1(a) is a perspective view showing the plug 10 from above, (b) is a perspective view shown from below, and (c) is a cross-sectional view taken along line I-I of (a). The plug 10 is a synthetic resin plug case 11 having a structure as a whole, and a plurality of metal plug contacts 12 and 13 as shown in Figs. 1(a) and 1(b). The plug contacts 12, 13 are electrically connected by contacting the socket contacts 22, 23 of the socket 20 of the opposite side connector, respectively. The plug 10 can be manufactured, for example, by insert molding.

The plug housing 11 is provided with a plug peripheral wall 11c having a substantially rectangular frame shape. The plug peripheral wall 11c has a pair of plug first wall portions 11a and a pair of plug second wall portions 11b. The pair of plug first wall portions 11a are disposed apart from each other in parallel. The pair of plug second wall portions 11b are disposed to be parallel to each other in a direction (y-axis direction) orthogonal to the longitudinal direction of the pair of first wall portions 11a, and the longitudinal direction of each of the pair of plug first wall portions 11a Both end portions (in the x-axis direction) are connected to the opposite inner side faces of the pair of plug second wall portions 11b. The bottom wall 11d is provided on the inner side surrounded by the plug peripheral wall 11c.

The plug housing 11 is a molded product of a synthetic resin such as liquid crystal polymer (LCP), and has insulation for maintaining the structure and insulation for ensuring insulation between the plug contacts 12 and 13.

The plurality of plug contacts 12 and 13 are disposed at intervals between the pair of plug first wall portions 11a along the longitudinal direction of the plug first wall portion 11a. The plug 10 shown in Fig. 1 is provided with a total of three plug contacts 12 and 13 in each plug first wall portion 11a, but the number is not limited to three, and may be more than three or more if it is two or more. less.

Fig. 5(a) is a perspective view showing the arrangement of all the plug contacts 12, 13 used in the plug 10 of Fig. 1 as in the plug housing 11, and (b) is a perspective view from below, ( c) is a VV cross-sectional view of (a). As shown in the fifth (a) and (b), the plug contacts 13 which are present at the end portions of the both end portions of the first wall portion 11a of the plug in the longitudinal direction (x-axis direction) are sandwiched between these and the like. The intermediate plug contact 12 is disposed between.

The intermediate plug contact 12 and the plug contact 13 at the end are configured to have a cross section of the plug outer side faces 12b, 13b and the plug inner side faces 12a, 13a which are connected in parallel with the respective end portions.
