## Abstract

A connector includes a housing and a base. The housing has a receiving hole for receiving a first-type plug. The base is assembled with the housing and has at least one foolproof structure. The foolproof structure and the base are formed as a single piece. The foolproof structure is protruded inside the receiving hole for blocking an insertion of an incompatible plug.

## Claims

### Claim 1

A connector comprising:
a housing having a receiving hole for receiving a first-type plug; and
a base assembled with the housing and having at least one foolproof structure protruding inside the receiving hole;
wherein the foolproof structure and the base are formed as a monolithic piece, and the foolproof structure is used to block an insertion of an incompatible plug.

### Claim 2 (depends on 1)

The connector according to claim 1, further comprising a circuit board connected with the base.

### Claim 3 (depends on 2)

The connector according to claim 2, wherein the circuit board has a circuit or an electric element disposed thereon.

### Claim 4 (depends on 1)

The connector according to claim 1, further comprising a shielding covering the housing and the base.

### Claim 5 (depends on 4)

The connector according to claim 4, wherein the shielding is metal or conductive material.

### Claim 6 (depends on 1)

The connector according to claim 1, wherein the material of the housing is plastic, carbon fiber or insulating material.

### Claim 7 (depends on 1)

The connector according to claim 1, wherein the base is plastic, carbon fiber or insulating material.

### Claim 8 (depends on 1)

The connector according to claim 1, wherein the foolproof structure comprises a barricade and an extension direction of the barricade tilts with an angle related to that of the end of the foolproof structure.

### Claim 9 (depends on 8)

The connector according to claim 8, wherein the barricade and the foolproof structure are formed as a single piece.

### Claim 10 (depends on 1)

The connector according to claim 1, wherein the foolproof structure is rotated or deformed when a first-type plug is inserted into the receiving hole.

### Claim 11 (depends on 1)

The connector according to claim 1, wherein the connector is an RJ11 connector, an RJ45 connector, a USB connector or a bridge.

### Claim 12 (depends on 1)

The connector according to claim 1, wherein the quantity of the foolproof structure is one or more.

### Claim 13 (depends on 1)

The connector according to claim 1, wherein the base is disposed at back side of the housing.

### Claim 14 (depends on 1)

The connector according to claim 1, wherein the base further comprises at least one lead electrically connected to a circuit board, an electric element or a system.

### Claim 15 (depends on 1)

The connector according to claim 1, wherein the base is formed by injection molding, molding or cutting.
