Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a receptacle connector and a connector assembly including the receptacle connector.

The present invention relates to a receptacle connector and a connector assembly including the same.

A connector is an electric component that connects an electrical signal by connecting a wire and a wire, a wire and a substrate, or a substrate and a substrate. In such a connector, the receptacle connector and the plug connector inserted and coupled to the receptacle connector constitute one assembly. Korean Patent Laid-Open Publication No. 2012-0103489 discloses a receptacle connector according to the prior art. A locking hook (unshown) is provided on the insertion hood portion 7 of the receptacle connector 1 according to the prior art, and the shell (non-drawing member) substantially defining the outer appearance of the receptacle connector 1. Such a locking hook is elastically deformed in the process of engaging the mating member, that is, the plug connector 31, with the insertion hood portion 7 and is caught by a groove (not shown) formed in the plug connector 31, The texter 1 and the plug connector 31 are inserted and held in a coupled state.

However, in the case of the conventional receptacle connector, a part of the shell formed of a metal material is cut to form a locking hook. Therefore, when the coupling and detachment of the receptacle connector 1 and the plug connector 31 are repeated many times, the receptacle connector 1 and the plug connector 31 are arbitrarily separated by a relatively small external force owing to the lowering of the elastic force of the locking hook Concerns arise. In particular, when the size of the receptacle connector 1 is relatively small, the size of the locking hook is substantially reduced, further increasing the possibility of causing the above-described problem.

FIG. 1 is a perspective view showing a receptacle connector according to a first embodiment of the present invention, FIG. 2 is an exploded perspective view showing a first embodiment of the present invention, and FIG. 3 is a sectional view showing a main part of a first embodiment of the present invention .

Referring to Figs. 1 to 3, a receptacle connector 1 according to the present embodiment includes a shell 100, a housing 200, a cover 300, and a plurality of terminals 400. Particularly, in the present embodiment, at least one locking rib 120 for holding the coupling state of the receptacle connector 1 and the plug connector (not shown) is provided in the shell 100, At least one support rib 320 for elastically supporting the cover 300 is provided on the cover 300.

More specifically, the shell 100 defines the appearance of the receptacle connector 1. The shell 100 is formed of a metal material and is formed in a polyhedral shape in which front and rear ends are opened as a whole. Therefore, a coupling space 100S in which a plug portion (not shown) provided in the plug connector is coupled is defined in the shell 100. [ The plug portion can be coupled substantially through the front end of the engagement space 100S.

In this embodiment, the shell 100 has a pair of first elastic cutouts 110 formed therein. The first elastic incision 110 is formed by cutting a part of an upper surface of the shell 100. The locking rib 120 may be formed at one side of the upper surface of the shell 100 corresponding to one end of the first elastic cutout 110 and toward the inside of the first elastic cutout 110, And extend in a direction to be coupled to the receptacle connector 1. [ The first elastic cutout 110 and the locking rib 120 may be formed by cutting substantially a part of the upper surface of the shell 100 in a substantially 'C' shape. The locking rib 120 includes an extension portion 121 and a locking portion 123. The extension portion 121 extends in a substantially horizontal direction. The locking portion 123 extends at least a part of the distal end of the extended portion 121 so as to be inclined downward. Therefore, at least a part of the locking portion 123 is positioned lower than the extending portion 121 relatively. When the plug connector is coupled to the receptacle connector 1, the locking portion 123 is inserted into a locking opening (not shown) formed in the plug connector. Of course, as shown in FIGS. 1 to 3, the first elastic incision part and the locking rib may be provided on the bottom surface of the shell 100 as well.

The housing 200 is inserted into the engagement space 100S through the rear end of the engagement space 100S. For example, the housing 200 may be formed of an insulating synthetic resin material. The housing 200 is provided with a coupling protrusion 210. The coupling protrusion 210 protrudes from the front surface of the housing 200 and extends toward the front end of the coupling space 100S when the housing 200 is coupled to the coupling space 100S. The coupling protrusion 210 is inserted into a coupling slot (not shown) formed in the plug portion when the plug portion is coupled to the coupling space 100S.

Meanwhile, the cover 300 is coupled to the shell 100 so as to surround the upper surface and both side surfaces of the shell 100. The cover 300 is also formed of a metal material in the same manner as the shell 100. In the cover 300, a pair of second elastic cutouts 310 are formed. The second elastic cutout part 310 is formed by cutting a part of the upper surface of the cover 300. At least a portion of the second elastic incision 310 is communicated with the first elastic incision 110 in the vertical direction while the cover 300 is coupled to the shell 100. A portion of the second elastic incision 310 corresponding to the projection of the locus due to the elastic deformation of the locking rib 120 may be communicated with the first elastic incision 110 up and down.

The support rib 320 may be formed at one side of the upper surface of the cover 300 corresponding to one end of the second elastic incision 310 and in the direction of the locking ribs 120 in the same direction.

The supporting rib 320 elastically supports a part of the locking rib 120 and the extending part 121 substantially corresponding to the base of the locking rib 120. In this embodiment, To this end, the bottom surface of the support rib 320 is in contact with or in close proximity to all or a portion of the extension 121. Therefore, in the present embodiment, when the locking rib 120 is elastically deformed while the supporting rib 320 is in contact with the locking rib 120, or when the locking rib 120 is elastically deformed, The support rib 320 elastically supports the locking rib 120 by contacting the locking rib 320 with the locking rib 120. In other words, the elastic deformation distance of the locking rib 120 may be limited by the supporting rib 320.

The terminal 400 is installed in the housing 200. The terminals 400 are spaced apart from each other in a direction orthogonal to the direction in which the plug connectors are coupled to the receptacle connector 1. A part of the terminal 400 is selectively connected to a terminal (not shown) provided in the plug connector, and another part of the terminal 400 is connected to a substrate (not shown). A part of the terminal 400 connected to the terminal of the plug connector is located on the upper surface of the coupling protrusion 210 and another part of the terminal 400 connected to the substrate is connected to the outside of the housing 200 . Although a part of the terminal 400 connected to the terminal of the plug connector, that is, the contact part 410 is shown as being disposed only on the upper surface of the coupling protrusion 210 in the present embodiment, The contact part 410 is disposed on the upper surface of the coupling protrusion 210 and the rest of the terminal 400 is disposed on the bottom surface of the coupling protrusion 210.

In this embodiment, the locking rib 120 is resiliently supported by the supporting rib 320. Therefore, in the process of engaging and disengaging the receptacle connector 1 with the plug connector, the locking rib 120 is resiliently deformed in a state where the locking rib 120 is elastically supported by the supporting rib 320 , A reduction in elastic force of the locking rib 120 and a disconnection of the plug connector from the receptacle connector 1 can be prevented.

Hereinafter, a receptacle connector according to a second embodiment of the present invention will be described in detail with reference to the accompanying drawings.

4 is a perspective view showing a receptacle connector according to a second embodiment of the present invention. The same components as those of the first embodiment of the present invention among the constituent elements of the present embodiment are referred to with reference to Figs. 1 to 3, and a detailed description thereof will be omitted.

Referring to FIG. 4, in the receptacle connector 2 according to the present embodiment, the support ribs 330 elastically support the locking portions 123 corresponding to the tip ends of the locking ribs 120. The support rib 330 extends from one side of the cover 300 corresponding to the other end of the second elastic cutout 310 in the direction opposite to the locking rib 120. [ And the bottom surface of the supporting rib 330 is positioned in contact with or adjacent to the upper surface of all or a part of the locking portion 123. [ Therefore, in the present embodiment, the tip end of the locking rib 120 is elastically supported by the supporting ribs 330, thereby minimizing the elastic force of the locking rib 120.

Hereinafter, a receptacle connector according to a third embodiment of the present invention will be described in detail with reference to the accompanying drawings.

5 is a perspective view showing a receptacle connector according to a third embodiment of the present invention. The same components as those of the first embodiment of the present invention among the constituent elements of the present embodiment are referred to with reference to Figs. 1 to 3, and a detailed description thereof will be omitted.

Referring to FIG. 5, in the receptacle connector 3 according to the present embodiment, a part of the cover 300 adjacent to the second elastic cutout 340 elastically supports the locking rib 120. To this end, the bottom surface of a portion of the cover 300 is positioned in contact with or adjacent to the base of the locking rib 120, i.e., the top surface of all or a portion of the extension 121. Therefore, in the present embodiment, it can be said that the second elastic cutout 340 is substantially smaller than the elastic cutout 310 of the first and second embodiments of the present invention described above. Also, in this embodiment, the bottom of the locking rib 120 is elastically supported by a part of the cover 300, so that a reduction in elastic force of the locking rib 120 can be minimized.

It is to be understood that the scope of the present invention is defined by the appended claims rather than by the embodiments described above and that various modifications and alterations made by those skilled in the art It is obvious that it can be done.
