Abstract

An electrical connector is provided for a mating connector to be inserted thereto. The electrical connector includes an insulating body having a tongue, and multiple terminals. A middle grounding sheet is located between the terminals in upper and lower rows, and has at least one first through hole. Each of left and right sides of the middle grounding sheet has a latch slot and a notch. The insulating body has a first insulating post entering the first through hole and a second insulating post entering the notch. A dimension of the second insulating post is larger than a dimension of the first insulating post. A metal shell frames outside the insulating body to form an insertion space. A first clearance between a first protruding portion and a shielding casing of the mating connector is more than or equal to 0.001 mm and less than or equal to 0.0449 mm.

First claim

What is claimed is:

1. An electrical connector, configured for a mating connector to be inserted thereto, the mating connector having a plastic body and a shielding casing wrapping the plastic body, the shielding casing having a first wall surface and a second wall surface connected with the first wall surface, and the electrical connector comprising:
an insulating body, having a base and a tongue provided at a front end of the base;
a plurality of terminals, formed in an upper row and a lower row, and respectively arranged on an upper surface and a lower surface of the tongue;
a middle grounding sheet, provided in the base and extending to the tongue, wherein the middle grounding sheet is located between the terminals in the upper row and the terminals in the lower row, the middle grounding sheet is provided with at least one first through hole, the middle grounding sheet has two latch slots and two notches concavely provided inward at a left side and a right side of the middle grounding sheet, each of the notches is located behind and adjacent to and connected to a corresponding one of the latch slots, the first through hole is located between the two notches, the insulating body has a first insulating post entering the first through hole and two second insulating posts correspondingly entering the notches, and a dimension of the second insulating post in a front-rear direction is larger than a dimension of the first insulating post in the front-rear direction; and
a metal shell, wrapping the insulating body, wherein the metal shell frames outside the insulating body to form an insertion space for insertion of the mating connector, the metal shell is provided with at least one first protruding portion protruding toward the insertion space, the first protruding portion has a first height along a protruding direction thereof, the first height is greater than or equal to 0.042 mm and less than or equal to 0.08 mm, the first protruding portion has a first position limiting surface facing the first wall surface, a first clearance is provided between the first position limiting surface and the first wall surface, and the first clearance is greater than or equal to 0.001 mm and less than or equal to 0.0449 mm.

2. The electrical connector according to claim 1 , wherein each of the notches is located closer to a central line of the middle grounding sheet in the front-rear direction relatively than each of the latch slots.

3. The electrical connector according to claim 2 , wherein each of the notches has a first inner edge adjacent to and connected to the corresponding one of the latch slots, and the first insulating post is formed integrally with the first inner edge and abuts forward the first inner edge.

4. The electrical connector according to claim 1 , wherein the mating connector has a retaining elastic sheet having a retaining portion fastened with a corresponding one of the latch slots, and when the retaining elastic sheet is fastened with the corresponding one of the latch slots, the retaining portion is located behind a front edge of the first protruding portion.

5. The electrical connector according to claim 1 , wherein the metal shell is provided with at least one second protruding portion protruding toward the second wall surface, the mating connector has a retaining elastic sheet, the corresponding one of the latch slots has a side edge abutting the retaining elastic sheet, and when the retaining elastic sheet is fastened with the corresponding one of the latch slots, the retaining elastic sheet is at least partially located between the second protruding portion and the side edge of the corresponding one of the latch slots in a left-right direction.

6. The electrical connector according to claim 5 , wherein the metal shell is provided with two second protruding portions protruding toward the second wall surface, one of the two second protruding portions is provided to be opposite to the side edge in the left-right direction, and the other of the two second protruding portions is located closer to an opening of the insertion space relative than the side edge.

7. The electrical connector according to claim 1 , wherein the metal shell has two first protruding portions provided opposite to each other in a vertical direction, the tongue is located between the two first protruding portions, the metal shell further has at least one second protruding portion provided on at least one side of the tongue in the left-right direction, a first vertical surface passes through ends of the two first protruding portions facing the insertion space and an end of the second protruding portion facing the insertion space, and the tongue is located behind the first vertical surface.

8. The electrical connector according to claim 7 , wherein the middle grounding sheet passes forward beyond a front end surface of the tongue and located behind the first vertical surface.

9. The electrical connector according to claim 1 , wherein the first height remains unchanged before and after the mating connector is inserted into the insertion space.

10. The electrical connector according to claim 1 , wherein each of the terminals has a mating portion exposed to a surface of the tongue, the terminals comprise at least one signal terminal, and the mating portion of the signal terminal and the first protruding portion are provided at least partially opposite to each other in a vertical direction.

11. The electrical connector according to claim 10 , wherein the mating connector has a plurality of contact terminals, the mating portion of each of the terminals has a horizontal plate surface forming an abutting position with one of the contact terminals, and the first protruding portion extends forward beyond the horizontal plate surface of the signal terminal and extends backward beyond the abutting position formed by the signal terminal and the contact terminal.

12. An electrical connector, configured for a mating connector to be inserted thereto, the mating connector having a plastic body and a shielding casing wrapping the plastic body, and the electrical connector comprising:
an insulating body, having a base and a tongue provided at a front end of the base;
a plurality of terminals, formed in an upper row and a lower row, and respectively arranged on an upper surface and a lower surface of the tongue;
a middle grounding sheet, provided in the base and extending to the tongue, wherein the middle grounding sheet is located between the terminals in the upper row and the terminals in the lower row, the middle grounding sheet is provided with at least one first through hole, the middle grounding sheet has two latch slots and two notches concavely provided inward at a left side and a right side of the middle grounding sheet, the first through hole is located between the two notches, each of the notches has a first inner edge relatively close to a front side of the tongue and connected to a corresponding one of the latch slots, a second inner edge formed to be relatively away from the front side of the tongue, and a third inner edge connecting the first inner edge and the second inner edge, the insulating body has a first insulating post entering the first through hole and two second insulating posts correspondingly entering the notches, and a dimension of the second insulating post in a front-rear direction is larger than a dimension of the first insulating post in the front-rear direction; and
