(34) As shown in FIG. 10, the stopping pieces 1110 are configured to abut against the end portions of the base plate 4200 to limit a movement of the base plate 4200 in a length direction thereof. The foldable tongue pieces 1140 are configured to be fitted into the notches 4210 formed in the end portions of the base plate 4200 and limit a movement of the base plate 4200 in a width direction thereof. A long edge of the base plate 4200 is held between the elastic holding members 1130 and the protruding pieces 1120 to limit a movable distance of the base plate 4200 in the thickness direction thereof.

(35) As shown in FIG. 8, the elastic holding members 1130 are a hooked elastic piece. A plurality of elastic holding members 1130 are formed on each long edge of the temperature exchange device receiving section 1100, and evenly spaced from each other. A pair of stopping pieces 1110 and one foldable tongue piece 1140 are formed on each short edge of the temperature exchange device receiving section 1100, and the one foldable tongue piece 1140 is located between the pair of stopping pieces 1110.

(36) As show in FIG. 8, in an exemplary embodiment, the elastic holding members 1130 and the positioning members (1110, 1120, 1140) are integrally formed on the bottom case 1000 and manufactured by punching the bottom case 1000.

(37) FIGS. 11A-11E are illustrative in showing a process of mounting the temperature exchange device 4000 of FIG. 9 with the temperature exchange device receiving section 1100 in the bottom case 1000 of FIG. 8.

(38) Firstly, as shown in FIG. 11A, the fin 4100 of the temperature exchange device 4000 is installed in the temperature exchange device receiving section 1100 of the bottom case 1000.

(39) Secondly, as shown in FIGS. 11B-11C, the temperature exchange device 4000 is tilted in order to interpose one side (left side in FIGS. 11B-11C) of the base plate 4200 of the temperature exchange device 4000 between the elastic holding members 1130 and the protruding piece 1120 of the bottom case 1000.

(40) Thirdly, as shown in FIGS. 11D-11E, the temperature exchange device 4000 is moved leftward and rotated to interpose the other side (right side in FIGS. 11D-11E) of the base plate 4200 of the temperature exchange device 4000 between the elastic holding members 1130 and the protruding pieces 1120 of the bottom case 1000. Then the temperature exchange device 4000 is moved rightward.

(41) Finally, as shown in FIG. 10, the foldable tongue piece 1140 is bent and fit in the notches 4210 in the end portions of the base plate 4200 of the temperature exchange device 4000, respectively.

(42) In this way, the temperature exchange device 4000 is mounted in the temperature exchange device receiving section 1100 of the bottom case 1000.

(43) As shown in FIGS. 12-13, pin receiving passageways 5200 mated with pins (not shown) of the top case 2000 and pin receiving passageways 5300 mated with pins 1200 (see FIG. 13) of the bottom case 1000 are formed in the circuit board 5000 around the opening 5100.

(44) With respect to FIG. 14, a partition 3000 is shown and includes a spring 3200 is formed on a surface 3100 of the partition 3000 facing the bottom case 1000 and configured to exert a spring force on the mating connector that is to be inserted into the port 1. In this way, a contact force between the temperature exchange device 4000 mounted on the bottom case 1000 and the mating connector inserted into the connector is enhanced, so that the temperature exchange device 4000 can reliably and tightly contact the mating connector, increasing the heat conducting effect between the mating connector and the temperature exchange device 4000.

(45) Similarly, if the connector includes only a single layer of ports, as shown in FIGS. 1-4, a spring may be formed on an inner surface of the top case, so as to exert a spring force on the mating connector inserted into the port.

(46) In an exemplary embodiment, the temperature exchange device 4000 may be mounted on a location of the bottom case 1000 corresponding to each port 1.

(47) In an exemplary embodiment, an additional temperature exchange device, for example the temperature exchange device 400 shown in FIGS. 1-4, is mounted on an outer surface of the top case. As shown in FIGS. 1-4, the additional temperature exchange device 400 is held on the outer surface of the top case 200 by means of a spring clamp 500, and the light guide pipe 600 is mounted on the additional temperature exchange device 400.

(48) In an exemplary embodiment, the connector is a female Small Form Factor (SFF) connector. The top case, the bottom case and the partition are made of metal.

(49) In another exemplary embodiment, as shown in FIG. 7, there is also provided a connector assembly. As shown in FIG. 7, the connector assembly includes a circuit board 5000 having a first surface and a second surface opposite to the first surface and formed with an opening 5100 therein, and the above connector set forth in the embodiments. The connector is mounted on the first surface of the circuit board 5000, and the temperature exchange device 4000 passes through the opening 5100 and protrudes from the second surface of the circuit board 5000.

(50) In another exemplary embodiment, an electrical apparatus (not shown) is also provided. The electrical apparatus includes a housing as well as a connector assembly set forth in the aforementioned embodiments. The circuit board 5000 of the connector assembly is assembled in the housing, and the fin 4100 of the temperature exchange device 4000 is located in a space between the second surface of the circuit board 5000 and an inner wall surface of the housing.

(51) Generally, the circuit board is mounted in the housing of the electrical apparatus, and the connector is mounted on the circuit board. In this case, in order to prevent metal soldering joints and metal pins of elements on the circuit bottom from contacting the metal housing of the electrical apparatus, there is always a space between the bottom of the circuit board and the inner wall of the housing, and the space between the bottom of the circuit board and the inner wall of the housing is large enough to receive the fin of the temperature exchange device therein. In this way, an additional heat radiating passage between the bottom case of the connector and the housing of the electrical apparatus is built up, improving the heat radiating effect for the connector.
