Abstract

An electrical connector is provided to be mated with a mating component. The electrical connector includes: a main body extending along a transverse direction; multiple terminals fixed to the main body and arranged along the transverse direction; and at least one insulating member connected with the main body and provided above the terminals. When the mating component is mated with the electrical connector, the terminals are electrically connected with the mating component, and each insulating member is in contact with at least one corresponding terminal, such that the insulating member move in a vertical direction and a front-rear direction simultaneously, which is equivalent to the case where a section of each terminal exposed from the main body is turned to be covered by the insulating member instead of being exposed in air.

First claim

a main body, extending along a transverse direction, wherein the main body has a grounding member, and at least one fixing arm extends from the grounding member;
a plurality of terminals, fixed to the main body and arranged along the transverse direction; and
at least one insulating member, connected with the main body and provided above the terminals, wherein when the mating component is mated with the electrical connector, the terminals are electrically connected with the mating component, and each of the at least one insulating member is in contact with at least one corresponding terminal of the terminals, such that the insulating member moves in a vertical direction,
wherein the at least one fixing arm is connected with the insulating member.

2. The electrical connector according to claim 1 , wherein the terminals comprise at least one pair of differential signal terminals, and when the mating component is not mated with the electrical connector, the insulating member is in contact with the at least one pair of differential signal terminals.

3. The electrical connector according to claim 1 , wherein when the mating component is not mated with the electrical connector, the insulating member is in contact with the at least one corresponding terminal, a contact area of the insulating member and the at least one corresponding terminal when the mating component is not mated with the electrical connector is smaller than the contact area of the insulating member and the at least one corresponding terminal when the mating component is completely mated with the electrical connector.

4. The electrical connector according to claim 1 , wherein the insulating member is not in contact with the mating component.

5. The electrical connector according to claim 1 , wherein the insulating member has an inclined surface, a portion of the inclined surface is not in contact with the at least one corresponding terminal when the mating component is not mated with the electrical connector, and the whole inclined surface is in contact with the at least one corresponding terminal when the mating component is completely mated with the electrical connector.

6. The electrical connector according to claim 5 , wherein:
the inclined surface is a lower surface of the insulating member slantly extending upward and backward from front thereof, and the inclined surface comprises a first region and a second region provided in a front-rear direction;
when the mating component is not mated with the electrical connector, only the first region is in contact with an upper surface of each of the at least one corresponding terminal; and
when the mating component is mated with the electrical connector and is in contact with the lower surface of each of the terminals, both the first region and the second region are in contact with the upper surface of each of the at least one corresponding terminal.

7. The electrical connector according to claim 1 , wherein each of the terminals comprises an extending section extending out of the main body, and the insulating member is provided on the extending section.

8. The electrical connector according to claim 7 , wherein the extending section comprises a contact portion located at a front end thereof and a connecting portion extending backward from the contact portion, the contact portion is electrically connected with the mating component, and the insulating member is located right above the connecting portion.

9. The electrical connector according to claim 7 , further comprising a plurality of insulating members and a shell accommodating the main body, the terminals and the insulating members, wherein the shell has a socket and a plurality of reserved slots located at one side of the socket and communicated with the socket, each of the insulating members is accommodated in at least one corresponding reserved slot of the reserved slots, and the extending section of each of the terminals is accommodated in a corresponding one of the reserved slots and is partially exposed from the socket.

10. An electrical connector configured to be mated with a mating component, the electrical connector comprising:
a main body, extending along a transverse direction, wherein the main body has a grounding member, and at least one fixing arm extends from the grounding member;
a plurality of terminals, fixed to the main body and arranged along the transverse direction, wherein the terminals comprises at least one pair of differential signal terminals; and
at least one insulating member, connected with the main body and provided on at least one corresponding pair of the differential signal terminals, wherein when the mating component is mated with the electrical connector, the mating component is electrically connected with the terminals, each of the at least one insulating member is in contact with the at least one corresponding pair of differential signal terminals, and the at least one corresponding pair of differential signal terminals drives a corresponding one of the at least one insulating member to move,
wherein the at least one fixing arm is connected with the insulating member.

11. The electrical connector according to claim 10 , wherein the insulating member is attached to surfaces of the at least one corresponding pair of the differential signal terminals.
