The state of the snap between the small package hot plug transceiver 1 and the electrical connection slot is easily known. Specifically, as shown in FIG. 5, when the small package hot plug transceiver 1 and the electrical connection slot are engaged with each other, the unlocking member 21 will substantially shield the top surface opening 10G; as shown in FIG. 6, when the unlocking member 21 is opposite to The body 10 is inclined, and most of the area of the top opening 10G is not shielded, and when the portion of the unlocking member 21 is obviously convexly protruded from the front end 10a of the body 10, the small package hot plug transceiver 1 is indicated. The electrical connection slots are in a state of not being engaged with each other.

Please refer to FIG. 12 to FIG. 15 , which are schematic diagrams of a third embodiment of a small package hot plug transceiver according to the present invention. As shown, the small package hot plug transceiver 1 includes a body 10, an unlocking assembly 20, two electrical signal connectors 30, two sets of flexible board assemblies 40, and a circuit board 50; the body 10 may include an upper cover The plate 11, the lower cover 12 and the front cover 13'. In the following, only the differences between the embodiment and the foregoing embodiments will be described in detail. For the parts that are not described, please refer to the foregoing embodiments.

One difference between this embodiment and the foregoing embodiment is that when the upper cover 11 , the lower cover 12 and the front cover 13 ′ are connected to each other, the front cover 13 ′ corresponds to a side exposed to the front end 10 a of the body 10 . It may be flush with an end surface of the front end 10a of the main body 10 corresponding to the upper cover 11 and the lower cover 12. The front cover 13' of the present embodiment is the same as the previous embodiment, and may have a metal layer 132 and a plastic layer 131. The plastic layer 131 is correspondingly exposed to the front end 10a of the body 10, and the metal layer 132 corresponds to For the detailed description of the metal layer 132 and the plastic layer 131, refer to the second embodiment, and details are not described herein again.

In the following, the embodiment of the present invention will be described in detail with particular reference to the parts not mentioned in the foregoing embodiments. However, the following detailed description is not limited to the application to the embodiment, and may be applied. In any of the foregoing embodiments.

As shown in FIG. 13 and FIG. 14 , the opposite ends of the two electrical signal connectors 30 are respectively defined as a plug end 30 a and a connecting end 30 b . The plug end 30 a is exposed at the front end 10 a of the body 10 , and the connecting end 30 b is It is correspondingly located in the accommodating space SP (as shown in FIG. 10). The circuit board 50 is fixedly disposed in the body 10, and the circuit board 50 is located in the accommodating space SP. Two flexible board assemblies 40, the opposite ends of each of the flexible board assemblies 40 are detachably connected to the electrical signal connector 30 and the circuit board 50, respectively, and each of the flexible board assemblies 40 transmits signals of the opposite electrical signal connectors 30 to Circuit board 50. The flexible board assembly 40, the electrical signal connector 30 and the circuit board 50 are detachably connected to each other. Thus, the flexible board assemblies 40, the electrical signal connectors 30 and the circuit board 50 can be independently detected before being assembled with each other. After the mutual assembly, it is easy to perform the detection independently; and since the electrical signal connector 30, the soft board assembly 40, and the circuit board 50 are detachably connected to each other, if any of the components are detected after the three are connected to each other, In the case of a problem, the component can only be replaced. It is particularly emphasized that each of the flexible board assemblies 40 and the circuit board 50 is not a composite board structure.

In addition, since the electrical signal connector 30, each of the flexible board assemblies 40, and the circuit board 50 are independently manufactured, the assembly of the flexible board assembly 40 can be performed by the replacement of the soft board assembly 40, so that the assembly can be completed. The small package hot plug transceiver 1 has good impedance matching and good signal transmission. It is worth mentioning that in the prior art, the electrical signal connector is directly soldered to the circuit board, so that the force generated during the plugging and unplugging of the electrical signal connector will directly act on the electrical signal connector and the circuit board. The solder joint between the two easily leads to the destruction of the solder joint between the electrical signal connector and the circuit board, which in turn leads to the destruction of the entire small package hot plug transceiver. In contrast, the electrical signal connector 30 of the small package hot plug transceiver 1 of the present invention is Through the flexible board assembly 40, the circuit board 50 is connected, and most of the force generated by the electrical signal connector 30 during the insertion and removal process will be absorbed by the soft board assembly 40, and the above-mentioned conventional knowledge will not easily occur. The problem of technical solder joint destruction.

In a practical application, the connection end 30b of each of the electrical signal connectors 30 may be provided with a signal terminal 31 and four ground terminals 32, and one end of each of the flexible board assemblies 40 may have a plurality of positioning holes; each electrical signal When the connector 30 and the flexible board assembly 40 are connected to each other, the signal terminal 31 and the ground terminal 32 can be correspondingly disposed in the plurality of positioning holes, and can be connected to each other by soldering.

As shown in FIG. 15, each of the flexible board assemblies 40 may include a flexible board body 41 and a support board 42. The support board 42 is disposed at one end of the board assembly 40 connected to the electrical signal connector 30. The support board 42 is used to strengthen The structural strength of the flexible board body 41. In practical applications, the structural rigidity of the support plate 42 may be higher than that of the soft plate body 41; in different applications, the support plate 42 and the soft plate assembly 40 may have the same structure and material.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
