Abstract

An electrical connector used for mating a mating connector includes an insulating body having multiple terminal slots in communication with an insertion space, multiple terminals, an insulating block. Each terminal slot has at least one side wall from which a depressed portion is depressed, the depressed portion is laterally in communication with the terminal slot. Each terminal has a connection portion connected to a contact portion and a soldering portion, a stopping portion protrudes from the connection portion and is located at the depressed portion. The insulating block is insert molded at a back end of the insulating body. A protruding portion protrudes from a front end of the insulating block and enters the depressed portion. The stopping portion is stopped in front of the protruding portion.

First claim

What is claimed is:

an insulating body, having an insertion space located at a front end thereof and a plurality of terminal slots in communication with the insertion space, wherein each of the terminal slots has two side walls disposed opposite to each other, a depressed portion is depressed from at least one of the side walls, and the depressed portion is laterally in communication with the terminal slot;
a plurality of terminals, respectively assembled to the terminal slots, wherein each of the terminals has one end provided with a contact portion located in the insertion space, and the other end provided with a soldering portion protruding from a back end of the insulating body, the terminal has a connection portion connected to the contact portion and the soldering portion, and a stopping portion protrudes from at least one side of the connection portion toward the depressed portion, so that the stopping portion is located at the depressed portion; and
an insulating block, insert molded at the back end of the insulating body, and wrapping the soldering portions, wherein a protruding portion protrudes from a front end of the insulating block forward and enters each of the depressed portions, and the stopping portions are stopped in front of the protruding portion.

2. The electrical connector according to claim 1 , wherein each of the stopping portions punctures a plate surface of the corresponding connection portion and extends backward.

3. The electrical connector according to claim 1 , wherein each of the depressed portion is depressed from a back end surface of the insulating body forward, and a distance exists between the depressed portion and each of a top wall and a bottom wall of the terminal slot.

4. The electrical connector according to claim 1 , wherein the depressed portion is depressed from the two side walls of each of the terminal slots, stopping portions protrude separately from two opposite sides of the connection portion of each of the terminals along opposite directions, the two stopping portions are disposed along a direction from front to rear, and the two stopping portions correspondingly resist inner wall surfaces of the two depressed portions.

5. The electrical connector according to claim 1 , wherein an accommodating space is depressed from a back end surface of the insulating body forward, a circuit board is partially accommodated in the accommodating space, the soldering portion of each of the terminals is soldered to one end of the circuit board, and the insulating block, the soldering portions and the circuit board are insert molded as integrally, and fill the accommodating space.

6. The electrical connector according to claim 1 , further comprising a metal shell wrapping the insulating body, wherein the metal shell is formed in a drawing manner, the insulating block is partially located in the metal shell, and the metal shell, the insulating body and the insulating block are fixed as a unit.

7. The electrical connector according to claim 1 , wherein the connection portion of each of the terminals is provided with a retaining portion close to the soldering portion, the retaining portion and an inner wall surface of the corresponding terminal slot are in interference fit, and the stopping portion protrudes from a plate surface of the retaining portion.

8. The electrical connector according to claim 7 , wherein a supporting portion protrudes from each of the connection portions close to the contact portion, the supporting portion is located between the contact portion and the retaining portion, the supporting portion protrudes toward a horizontal center surface of the insulating body, and the supporting portion resists the inner wall surface of the terminal slot.

9. The electrical connector according to claim 1 , wherein two rows of terminal slots are provided to run through the insulating body along a direction from front to rear, the terminals are correspondingly located at the two rows of terminal slots and are arranged into an upper row and a lower row in the insulating body, a shielding sheet is inserted into the insulating body and is located between the upper and lower rows of terminals, and a plate surface of each of the terminals is perpendicular to a plate surface of the shielding sheet.

10. The electrical connector according to claim 9 , wherein the shielding sheet has a base portion located at a back end of the terminal slot, a latch arm extends from each of two opposite sides of the base portion forward, a hollowing portion is depressed from each of two opposite sides of the insulating body and is in communication with the insertion space, the latch arms are respectively accommodated in the hollowing portions and stretched into the insertion space, two retaining arms protrude from the base portion between the two latch arms, each of the retaining arms is located between a terminal at the outermost side and a terminal adjacent to the terminal at the outermost side, the insulating body is provided with two fixing slots between the two rows of terminal slots, and the two retaining arms are correspondingly fixed to the two fixing slots.

11. An electrical connector for mating a mating connector, comprising:
an insulating body, having an insertion space located at a front end thereof for the mating connector to be inserted therein, and a plurality of terminal slots in communication with the insertion space, wherein each of the terminal slots has two side walls disposed opposite to each other, a depressed portion is depressed from at least one of the side walls, and the depressed portion is laterally in communication with the terminal slot; and
a plurality of terminals, respectively assembled to the terminal slots, wherein each of the terminals has one end provided with a contact portion located in the insertion space and mating the mating connector, and the other end provided with a soldering portion protruding from the insulating body, the terminal has a connection portion located between the contact portion and the soldering portion, a stopping portion protrudes from at least one side of the connection portion toward the depressed portion, and the stopping portion resists an inner wall surface of the depressed portion,
wherein each of the depressed portions is depressed from a back end surface of the insulating body forward, and a distance exists between the depressed portion and each of a top wall and a bottom wall of the terminal slot.

12. The electrical connector according to claim 11 , wherein each of the stopping portions punctures a plate surface of the connection portion of the corresponding terminal and extends backward.

13.
