Description

  The present invention relates to a connector and a connector device. In particular, the present invention relates to a connector such as a plug and a socket used for electrical connection between two printed wiring boards, and a connector device including a plug and a socket.

  2. Description of the Related Art Conventionally, a connector device for directly connecting two printed wiring boards directly without using a cable is known. This connector device comprises a plug mounted on one printed wiring board and a socket mounted on the other printed wiring board. By fitting the plug into the socket, the printed wirings of both printed wiring boards can be connected to each other. They are electrically connected (see, for example, Patent Document 1).

  In recent years, the connector has been reduced in size and thickness, and the strength of the connector has been reduced. This is because the housing of the connector is made of a resin material, and it has become difficult to maintain the required strength due to the reduction in size and thickness. For this reason, there is a possibility that the housing may be broken because it cannot withstand the stress generated during the connector insertion / extraction operation.

  FIG. 19A shows the state of the connector removal work as an example. From the state in which the two printed wiring boards 30 and 40 are connected by the fitting of the plug 10 and the socket 20, the end of one printed wiring board 30 is lifted with a finger 50 and mounted on the other printed wiring board 40. The plug 10 is removed from the socket 20 formed. However, in such an operation, there is a possibility that stress is concentrated at a position indicated by reference character B in FIG. 19 (b) and FIG. . This is because this portion is thin and formed only from a resin material, and has a lower strength than the other portions, cannot withstand external forces applied during the extraction operation, and easily breaks. For this reason, this periphery is reinforced with a reinforcement metal fitting (for example, refer to patent documents 1).

  In the plug connector disclosed in Patent Document 1, a metal plug member functioning as a reinforcing member is provided on 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 reinforces the connection portion between the first plug wall portion and the second plug wall portion.

  Moreover, in the receptacle connector disclosed in Patent Document 1, a metal receptacle member that functions as a reinforcing member is provided on the first receptacle wall. The metal receptacle member has a pair of sixth receptacle plate portions embedded in the second receptacle wall portion, and reinforces the connection portion between the first receptacle wall portion and the second receptacle wall portion.

Japanese Patent Laying-Open No. 2006-331679 (FIGS. 3, 4, 7, and 8)

  However, in the plug connector disclosed in Patent Document 1, since the plug member having the third plug plate portion, which is a reinforcing metal fitting, is configured separately from the plug contact, the plug contact located at the end and the reinforcing metal fitting are provided. In between, there were not a few thin and weak housing parts made only of resin material. Further, when a separate reinforcing metal fitting is provided, there is a problem in that it is impossible to meet the demand for further miniaturization of the connector because an installation space is required for the housing.

  Further, in the receptacle connector disclosed in Patent Document 1, since the receptacle member having the sixth receptacle plate portion which is a reinforcing metal fitting is configured separately from the receptacle contact, the receptacle contact located at the end and the reinforcing metal fitting are provided. In between, there were not a few thin and weak housing parts made only of resin material.

[First Embodiment]
1A is a perspective view of the plug 10 as viewed from above, FIG. 1B is a perspective view of the plug 10 as viewed from below, and FIG. 1C is a cross-sectional view taken along the line II of FIG. As shown in FIGS. 1A and 1B, the plug 10 includes a synthetic resin plug housing 11 and a plurality of metal plug contacts 12 and 13 that form the entire structure. The plug contacts 12 and 13 are adapted to achieve electrical connection by making contact with the socket contacts 22 and 23 of the socket 20 which is a counterpart connector, respectively. The plug 10 can be manufactured by insert molding, for example.

  The plug housing 11 includes a plug outer peripheral wall 11c having a substantially rectangular frame shape. The plug outer 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 spaced apart from each other in parallel. The pair of plug second wall portions 11b are spaced apart from each other in a direction perpendicular to the longitudinal direction of the pair of plug first wall portions 11a (y-axis direction), and the length of each of the pair of plug first wall portions 11a. Both ends in the direction (x-axis direction) are connected to opposing inner side surfaces of the pair of plug second wall portions 11b. A bottom wall 11d is provided on the inner side surrounded by the plug outer peripheral wall 11c.

  The plug housing 11 is a molded product of a synthetic resin such as a liquid crystal polymer (LCP), and has rigidity 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 on each of the pair of plug first wall portions 11a at intervals along the longitudinal direction of the plug first wall portion 11a. In the plug 10 shown in FIG. 1, a total of three plug contacts 12 and 13 are arranged on each plug first wall portion 11a. However, the number is not limited to 3, and 3 as long as it is 2 or more. More or less.

  FIG. 5A is a perspective view showing all the plug contacts 12 and 13 used in the plug 10 of FIG. 1 as arranged in the plug housing 11, and FIG. 5B is a perspective view seen from below. (C) is VV sectional drawing of (a). As shown in FIGS. 5 (a) and 5 (b), the plug contacts 13 at the ends existing at both ends in the longitudinal direction (x-axis direction) of the plug first wall portion 11a are disposed between them. An intermediate plug contact 12 is used.

  The intermediate plug contact 12 and the plug contact 13 at the end have a substantially U-shaped cross section in which the plug outer surface portions 12b and 13b and the plug inner side surface portions 12a and 13a that are parallel to each other are connected between the respective end portions as a common configuration. It has plug U-shaped parts 12u and 13u. Both the plug outer surface portions 12b and 13b and the plug inner side surface portions 12a and 13a are arranged to face the side surface of the plug first wall portion 11a. That is, each of the plug contacts 12 and 13 is arranged such that the plug U-shaped portions 12u and 13u cover the plug first wall portion 11a.

  Further, as a common configuration, engagement recesses 12d and 13d are formed in the plug outer surface portions 12b and 13b of the plug U-shaped portions 12u and 13u in the plug contacts 12 and 13, respectively. The engagement recesses 12d and 13d are engaged with engagement protrusions 22f and 23f formed on the socket inner side surfaces 22a and 23a of the socket U-shaped portions 22u and 23u on the socket contacts 22 and 23 side shown in FIG. It is like that. Thereby, the contact of the plug contacts 12 and 13 and the socket contacts 22 and 23 becomes more reliable.

  Moreover, each plug contact 12 and 13 has the plug terminal piece 12c and 13c which protrude outside from the lower end part of the plug U-shaped part 12u and 13u as a common structure. The plug contacts 12, 13 can be formed, for example, by stamping and bending a thin metal plate such as a copper alloy and then performing gold plating or the like.

  As shown in FIGS. 5A and 5B, among the plurality of plug contacts 12 and 13 arranged on each plug first wall portion 11a, the plug located at the end in the longitudinal direction of the plug first wall portion 11a. Each of the contacts 13 is provided with a plug reinforcing portion 13e. The plug reinforcing portion 13e is integrally extended from the end plug contact 13 along the longitudinal direction, and at least a part of the plug reinforcing portion 13e is embedded in the plug second wall portion 11b. ing.

  Since the plug reinforcing portion 13e is integrally formed from the plug contact 13 at the end, it is convenient to manufacture the plug reinforcing portion 13e using the same metal material as the plug contact 13. However, since the plug reinforcing portion 13e is intended to reinforce the plug housing 11, gold plating or the like may be omitted as necessary.

  The plug reinforcement portion 13e is a rectangular plate material as viewed from the width direction (y-axis direction) of the plug first wall portion 11a. However, as long as it has a reinforcing function, the plug reinforcement portion 13e can be a plate material having an arbitrary shape. Instead, for example, a rod-like member can be used.

  With the configuration described above, in the plug 10 according to the present embodiment, each of the end plug contacts 13 has the plug reinforcing portion 13e, and the plug reinforcing portion 13e is integrally formed with each of the end plug contacts 13 along the longitudinal direction.

Therefore, the plug housing 11 in the range from the housing portion of the plug first wall portion 11a where the end plug contact 13 exists to the plug second wall portion 11b can be reliably reinforced without leakage. Since the plug housing 11 in this range is a portion where breakage or the like is likely to occur when the plug 10 is inserted or removed, breakage such as breakage during the insertion or removal operation can be effectively prevented. Even if breakage such as breakage occurs in the above range of the plug housing 11 during the insertion / extraction operation, the shape of the plug housing 11 itself can be maintained by the plug reinforcing portion 13e formed integrally from the plug contact 13 at the end. . The end plug contact 13 itself is also formed integrally with such a plug reinforcing portion 13e, so that the end plug contact 13 against the external force in the width direction (y-axis direction) of the plug first wall portion 11a. The strength of can be increased. Further, although it is possible to coexist with a separate reinforcing metal fitting from the plug contact 13 at the end, effective reinforcement can be performed without using a separate reinforcing metal fitting. Since it is not necessary to use a separate reinforcing metal fitting, it is not necessary to secure an installation space for the plug housing 11, and the plug 10 can be downsized.

  The plug second wall portion 11b of the plug housing 11 is provided with a metal plug lock portion 18 shown in FIG. The plug lock portion 18 is made of, for example, copper alloy plated with silver, tin, or the like, and has an outer surface provided with a lock recess 18a and an inner surface lower end provided with an outward fixing piece 18b. When the plug 10 is fitted into the socket 20, the lock recess 18 a of the plug lock portion 18 is engaged with the lock protrusion 28 a provided on the inner surface of the reinforcing metal fitting 28 on the socket 20 side, so that the plug 10 and the socket 20 are engaged. The fitting is more secure.

  As shown in detail in FIGS. 5 (a) and 5 (b), the plug reinforcing portion 13e integrally extends outward in the longitudinal direction from the plug inner side surface portion 13a of the plug U-shaped portion 13u in the plug contact 13 at the end. It is formed in a plate shape. The thickness of the plate-like plug reinforcing portion 13e is equal to the thickness of the integrally formed plug inner side surface portion 13a, but the thickness may be changed as necessary.

  Therefore, the plate-like plug reinforcing portion 13e is arranged so as to be substantially parallel to the inner side surface of the plug first wall portion 11a of the plug housing 11. That is, the plate-like plug reinforcing portion 13e is erected in the height direction (z-axis direction) of the plug first wall portion 11a and the plug second wall portion 11b of the plug housing 11. For this reason, it has high rigidity with respect to the external force applied from the height direction to the connection portion between the plug first wall portion 11a and the plug second wall portion 11b of the plug housing 11 and the periphery thereof when the connector is inserted and removed.
