The housing 10 of the present embodiment is assembled by the first housing 100a and the second housing 100b, and if the housing 10 is integrated, the plurality of through grooves 102 are formed on the first inner surface 10a of the housing 10.

The circuit board 11 is disposed in the accommodating space 101 and protrudes from the first end face 10d of the housing 10. In an embodiment, the housing 10 has a plug opening 103, the plug opening 103 is opened on the first end surface 10d of the housing 10, specifically, the circuit board 11 has a connection end 11a and a plug end 11b, the connection end 11a of the circuit board 11 is located in the accommodating space 101, and the plug end 11b of the circuit board 11 is located outside the first end surface 10d of the housing 10.

The shielding element 13 is disposed in the accommodating space 101 and covers the plurality of through grooves 102 to separate the accommodating space 101 from the plurality of through grooves 102, so that the shielding element 13 blocks the communication between the plurality of through grooves 102 and the accommodating space 101, and simultaneously blocks the communication between the accommodating space 101 and the outside of the electrical connector 1. Specifically, the shielding element 13 of the present embodiment is disposed on the first inner surface 10a of the housing 10, the shielding element 13 closes the plurality of first openings 1021 formed on the first inner surface 10a of the housing 10 by the plurality of through slots 102 to block the communication between the plurality of through slots 102 and the accommodating space 101, and the exterior of the electrical connector 1 is communicated with the plurality of through slots 102 but blocked by the shielding element 13 and not communicated with the accommodating space 101. In other words, external air flow of electrical connector 1 can enter corresponding through slots 102 from plurality of second openings 1022 (or plurality of third openings 1023) and flow out from plurality of third openings 1023 (or plurality of second openings 1022). The two sides of the shielding element 13 of the present embodiment are also respectively abutted against the two second inner surfaces 10b, so as to ensure that no gap is formed between the shielding element 13 and the two second inner surfaces 10b, and block the communication between the accommodating space 101 and the outside of the electrical connector 1.

When the electrical connector 1 is plugged into the mating connector, the shielding member 13 can prevent electromagnetic interference generated by the circuit board 11 and the cable 12 during signal transmission, in other words, the shielding member 13 seals the plurality of through slots 102, so as to effectively prevent electromagnetic generated by the circuit board 11 and the cable 12 during signal transmission from leaking from the plurality of through slots 102 to the outside of the electrical connector 1 in a large amount, and prevent external electromagnetic from entering the accommodating space 101 from the plurality of through slots 102 to affect the operation of the circuit board 11 and the cable 12. Therefore, the shielding member 13 of the present embodiment achieves the electromagnetic shielding effect, and effectively reduces the problem of crosstalk occurring in the signal transmission process of the electrical connector 1, so that the electrical connector 1 has good signal transmission performance.

In addition, if the shielding element 13 is made of a material with a better heat conduction effect, such as metal, it can also concentrate heat energy, and when the electrical connector 1 is in use, the heat energy generated by the circuit board 11 and the cable 12 can be concentrated on the shielding element 13. A fan or other air extracting device may be disposed outside the electrical connector 1, where the fan or the air extracting device can disturb the airflow outside the electrical connector 1, that is, the airflow outside the electrical connector 1 can flow, the airflow outside the electrical connector 1 can enter the corresponding through groove 102 from the second opening 1022 (or the third opening 1023), and the airflow entering the through groove 102 takes away the heat energy on the shielding element 13 and flows out from the third opening 1023 (or the second opening 1022), so as to improve the heat dissipation effect of the electrical connector 1.

The shielding element 13 of the present embodiment can be movably disposed on the housing 10, so the material of the shielding element 13 can be different from or the same as the material of the housing 10, and the material of the housing 10 and the material of the shielding element 13 can be selected according to the required performance of the electrical connector 1. When the electrical connector 1 is required to have a good electromagnetic shielding effect and a good heat dissipation effect, the material of the housing 10 and the material of the shielding member 13 may be materials having both electromagnetic shielding effect and heat conduction effect; alternatively, the material of the housing 10 may have a good heat conduction effect, and the material of the shield 13 may have a good electromagnetic shielding effect. If the electrical connector 1 is biased to perform the electromagnetic shielding function, the shielding element 13 may be made of a material with a good electromagnetic shielding effect, such as conductive plastic or electroplated plastic, and the housing 10 may be made of a material with both electromagnetic shielding effect and heat conduction effect, especially a material with an electromagnetic shielding effect better than heat conduction effect. When the electrical connector 1 is subjected to a heavy heat dissipation effect, the shielding element 13 may be made of a material having a good heat conduction effect, such as metal, and the housing 10 may be made of a material having both an electromagnetic shielding effect and a heat conduction effect, especially a material having a heat conduction effect superior to the electromagnetic shielding effect.

As described above, since the shielding element 13 is separated from the housing 10, the material of the housing 10 and the material of the shielding element 13 can be selected according to the required performance of the electrical connector 1, so as to ensure that the electrical connector 1 can achieve the predetermined performance to meet the user's requirement, and the shielding element 13 and the housing 10 are separately manufactured to simplify the manufacturing and save the cost.

When the electrical connector 1 is to be disconnected from the mating connector, the locking member 15 is pulled to release the locking state between the locking member 15 and the mating connector, so that the electrical connector 1 can be disconnected from the mating connector.
