The second lead frame 28 may be coupled to the receptacle body 20 so as to be positioned on the side of the control element 24 in the second direction (SD arrow direction, shown in FIG. 3).

The optical element 22 is for transmitting an optical signal. The optical element 22 may be coupled to the receptacle body 20. The optical element 22 may be coupled to the receptacle body 20 such that the optical element 22 faces upward from the bottom surface 205 of the receptacle body 20 (direction of UD arrows, as shown in FIG. 2). The optical element 22 is located between the control element 24 and the plug assembly 4. The optical element 22 and the control element 24 may be electrically connected by wire bonding. When the optical connector 1 according to the present invention is used as a transmitter, the optical device 22 may be a light emitting device such as a laser diode, a vertical cavity surface-emitting laser (VCSEL) Device.

That is, the control element 24 is coupled to the receptacle body 20 so as to be positioned between the optical element 22 and the first lead frame 26.

Therefore, the optical connector 1 according to the present invention can improve the connection stability by reducing the length of the bonding wire and reduce the production cost through material reduction.

Specifically, since the control device 24 must receive the ground and data signals D1 + and D1- from the first lead frame 26 to drive the optical device 22, the optical device 22 22 and the first lead frame 26, respectively. On the other hand, when the control element 24 and the first lead frame 26 are disposed with the optical element 22 therebetween, the distance between the control element 24 and the first lead frame 26 is The length of the bonding wire for connecting the control element 24 and the first lead frame 26 becomes long. Further, when the optical element 22 and the control element 24 are disposed with the first lead frame 26 therebetween, the distance between the optical element 22 and the control element 24 becomes longer The length of the bonding wire for connecting the optical element 22 and the control element 24 is increased. When the length of the bonding wire is increased, the risk of disconnection of the bonding wire due to an external force such as vibration or shaking increases, and the production cost increases due to the increase of the material. Therefore, the optical connector 1 according to the present invention is characterized in that the control element 24 is positioned between the optical element 22 and the first lead frame 26 with respect to the second axial direction (Y-axis direction) The connection stability by the bonding wire can be improved and the production cost can be reduced.

The elastic connecting member 282b may be disposed between the connecting member 282a and the frame body 280 with reference to the first axial direction (X-axis direction). The elastic connecting member 282b and the connecting member 282a may be integrally formed. In this case, the elastic connecting member 282b and the connecting member 282a may be formed by bending a plate material.

Accordingly, the optical connector 1 according to the present invention can further increase the connecting force between the second lead frame 28 and the cover portion 3 through the increase of the elastic displacement.

The inclination angle of the connecting member 282a inclined with respect to the frame body 280 may be an acute angle. Accordingly, the optical connector 1 according to the present invention allows the cover portion 3 to be easily connected to the connecting member 282a, while the connecting force between the connecting mechanism 282a and the cover portion 3 Can be increased. This is because when the inclined angle is a right angle or an obtuse angle, the connecting member 282a is not elastically moved as the cover portion 3 is connected to the connecting member 282a.

The insertion member 37 may be formed on the cover body 30 so as to be positioned between the inner side wall 203 of the receptacle body 20 and the receiving groove 201. The insertion member 37 may be formed to surround the coupling hole 36 together with the cover body 30, but the present invention is not limited thereto.

The insertion member 37 may be inserted into the engagement groove 41a or may be spaced apart from the engagement groove 41a depending on the position of the cover body 30. [ The insertion member 37 is spaced from the latching groove 41a in a state where the cover body 30 is coupled to the receptacle body 20 as shown in FIG. 11b, and the cover body 30 is separated from the second The insertion member 37 can be inserted into the latching groove 41a as it moves in the direction of arrow SD. Thus, the plug main body 40 can be guided by the insertion member 37 inserted in the latching groove 41a and moved in the upward direction (the direction of the arrow UD). Therefore, the optical connector 1 according to the present invention can improve the ease and accuracy of the operation of releasing the engagement of the plug main body 40.

16, the projecting member 41 includes a guide surface 41b which is disposed in the direction of the engagement groove 41a and guides movement of the insertion member 37 inserted into the engagement groove 41a can do.

The guide surface 41b may be formed so that the height with respect to the third axis direction (Z-axis direction) becomes higher toward the first direction (FD arrow direction). When the projecting member 41 includes the guide surface 41b, the insertion member 37 inserted into the retaining groove 41a has a shape corresponding to the guide surface 41b of the projecting member 41 (Shown in FIG. 12).

The guide surface 37a of the insertion member 37 may be formed so that the height with respect to the third axis direction (Z-axis direction) decreases toward the second direction (SD arrow direction). The guide surface 41b of the projecting member 41 and the guide surface 37a of the insertion member 37 are formed to have inclined surfaces corresponding to each other, (UD arrow direction) by being guided by the guide surface 37a of the insertion member 37 inserted in the guide groove 37a. Therefore, the optical connector 1 according to the present invention can improve ease of operation for moving the plug main body 40.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Will be clear to those who have knowledge of.
