Referring to fig. 1 and 2, the connector 100 includes a housing 1, an insulating body 2, a terminal assembly 3 and a light guide 4, wherein the insulating body 2 includes a front wall 21, a top wall 22 and a bottom wall 23 opposite to each other, and two side walls 24 opposite to each other, the insulating body 2 is recessed backward from the front wall 21 to form two insertion portions 25 capable of inserting and holding the adaptive connector, and the two insertion portions 25 are spaced apart from each other by a partition 26 connected between the two side walls 24. The two terminal assemblies 3 can be respectively mounted to the insulative housing 2 from the rear side of the insulative housing 2 with the connection terminals extending into the mating parts 25 to respectively make electrical connection with the terminal assemblies 3 when the mating connector is inserted into any one of the mating parts 25. The upper and lower sides of the insulating body 2 are respectively provided with a slot 27, and the two light guide bodies 4 are respectively inserted and fixed in the two slots 27.

The housing 1 made of metal covers the periphery of the insulating body 2 after the light guide 4 and the terminal assembly 3 are assembled, and is clamped and fixed with the insulating body 2 by the clamping claws 11 connected with the housing. The bottom of the housing 1 is integrally connected with a mounting claw 12 adapted to be fixedly connected with an external circuit board 200, and the pins of the two terminal assemblies 3 are extended downward to be soldered to the circuit board 200, so that the connector 100 is assembled with the circuit board 200 to form a connector module. In the present embodiment, the connector 100 is exemplarily configured as an RJ45 receptacle connector, and the plug portion 25 is correspondingly configured as a jack structure adapted to be plugged with an RJ45 plug connector (i.e., an adapter connector).

As shown in fig. 2 and fig. 3, in order to facilitate the user to determine whether the two terminal assemblies 3 of the RJ45 socket connector are reliably connected and communicated with the RJ45 plug connector, two sets of light emitting elements 300 electrically connected to the two terminal assemblies 3 are disposed on the circuit board 200, and the two sets of light emitting elements 300 are configured to be in a first operating state when the terminal assembly 3 electrically connected thereto is connected and communicated with the RJ45 plug connector, and to be in a second operating state different from the first operating state when the terminal assembly 3 electrically connected thereto is disconnected and communicated with the RJ45 plug connector.

The first working state and the second working state can be either one of light emitting and light out, or light emitting in different colors or flashing at different frequencies. The two light guiding bodies 4 serve as a propagation medium to propagate the light emitted by the two sets of light emitting elements 300 to the front wall 21 of the insulating body 2, so that the user can observe the corresponding light through the window on the metal shell 1, which is opposite to the light guiding body 4, and the user can determine the communication state of the RJ45 socket connector based on whether the light is observed, the observed light color or the light flicker frequency. In this embodiment, light emitting component 300 is LED lamp bead, and the power consumption is reduced.

Specifically, as shown in fig. 4, in the present embodiment, the light guide 4 may be made of a material such as PMMA (polymethyl methacrylate) or PC (polycarbonate) which is an optically dense medium with respect to air and the insulating body 2, so as to improve the reflectivity when light propagates through the light guide 4. Along the propagation direction of the light, two opposite end surfaces of the light guide 4 are a light incident surface 41 and a light emitting surface 42, respectively, and a portion of the light guide 4 extending between the light incident surface 41 and the light emitting surface 42 forms a light guide path for propagating the light. The light incident surface 41 of the light guide 4 faces the light emitting element 300 to receive the light emitted from the light emitting element 300, and the light is transmitted through the light guide path and emitted from the light emitting surface 42, so that the light emission of the light guide 4 is observed from the outside of the connector 100.

Referring to fig. 1 again, in order to facilitate the user to easily observe and determine the light emitting condition of the light guiding body 4 and improve the appearance quality of the connector 100, the light emitting surface 42 of the light guiding body 4 is substantially rectangular, and the length of the rectangle is set to be slightly smaller than the width of the front wall 21 of the housing 1 and the insulating body 2, so that a larger light emitting area is obtained. Compared with the area of the light emitting surface, after the light emitted by the LED lamp beads with smaller irradiation area is emitted from the light emitting surface 42 of the light guide body 4, the light emitting part of the light emitting surface 42 of the light guide body 4 is only concentrated at the part opposite to the LED lamp beads along the light guide path, so that the light emitting brightness of the light emitting surface 42 of the light guide body 4 is uneven, and the visual sense is not good.

To this end, referring to fig. 4 again, in the present embodiment, the light emitting surface 42 of the light guiding body 4 is provided with a first light equalizing structure 44, and the first light equalizing structure 44 is configured to uniformly diffuse the light emitted from the light emitting surface 42, so as to equalize the light emitting brightness of the light emitting surface 42 and improve the visual sensation. The first light equalizing structure 44 is preferably uniformly disposed on all portions of the light emitting surface 42, so as to facilitate processing and further equalize the brightness of the light emitted from each portion of the light emitting surface 42.

As shown in fig. 5, in the present embodiment, the first light-equalizing structure 44 includes a plurality of linearly-distributed light-equalizing teeth 441. Each light-equalizing tooth 441 extends along the thickness direction of the light guide body 4, and a plurality of light-equalizing teeth 441 form an intermittent arc structure, when light emitted by the LED lamp bead enters the light incident surface 41 of the light guide body 4 and propagates to the light emergent surface 42 through the light guide passage, if the light exits the light emergent surface 42 between adjacent light-equalizing teeth 441, since the light emergent surface 42 is substantially perpendicular to the propagation direction of the light in the light guide body 4, the part of light still substantially exits along the original propagation path; if the light is transmitted to the light equalizing teeth 441, since each part of the light equalizing teeth 441 intersects with the transmission direction of the light in the light guide body 4, the transmission path of the light is changed when the light is emitted from the light equalizing teeth 441, so that the light emitted from the light emitting surface 42 is uniformly diffused. The directions of the arrows in fig. 5 are the propagation directions of the light exiting from the light equalizing teeth 441.

Alternatively, in other embodiments, light-equalizing teeth 441 may be distributed in an array on light-exiting surface 42, which is not limited thereto. Meanwhile, the light-equalizing teeth 441 may form other light-equalizing structures such as a continuous arc, an interrupted trapezoid, a continuous trapezoid, or a sine wave, which is not limited herein.

In order to adapt to the assembly of the circuit board 200 and the connector 100, that is, to adapt to the light emitting direction of the LED lamp bead being perpendicular to the light emitting direction of the light guide 4, in the present embodiment, the light guide 4 may be bent, and the bent portion of the light guide 4 has a light reflecting surface 43, so that the light emitted by the LED lamp bead and incident on the light incident surface 41 of the light guide 4 is reflected to the light emitting surface 42 by the light reflecting surface 43, as shown by the arrow in fig. 3.

Preferably, the light reflection surface 43 may be provided with a second light equalizing structure for uniformly diffusing the light reflected to the light exit surface 42 with reference to the first light equalizing structure 44, so that the light can be dispersed when propagating to the light reflection surface 43, thereby improving the light equalizing effect at the light exit surface 42. Further, the light incident surface 41 may be provided with a third light equalizing structure for uniformly diffusing the light incident on the light guide 4 with reference to the first light equalizing structure 44. The first light equalizing structure 44, the second light equalizing structure, and the third light equalizing structure may be formed on the surface or inside the light guide 4 by laser etching.

In other embodiments, the light emitting surface 42, the light incident surface 41, and/or the light reflecting surface 43 of the light guide 4 may be provided with a notch structure different from the above-described light equalizing teeth 441, for example, the light emitting surface 42 may be provided with notch structures having different densities, depths, and shapes at different positions, so as to obtain a specific light emitting effect.

It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Numerous obvious variations, adaptations and substitutions will occur to those skilled in the art without departing from the scope of the utility model. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
