Abstract

A data card with a USB plug (207) includes a housing (201) and a cap (203). A data card antenna (205) is disposed in the cap. The cap further has at least one cap wing (209) extending from an opening of the cap. A cap antenna contact (211) is provided on the cap wing. The cap antenna contact is electrically connected with the antenna in the cap. A housing antenna contact (213) is provided on an end portion of the housing. The housing antenna contact is electrically connected with a circuit in the housing. When the cap is relatively fixed to a bottom end of the housing, the cap antenna contact is electrically connected with the housing antenna contact. The disposition of the antenna in the cap reduces a body size of the data card, and therefore reduces a size of the entire data card.

Claims

1. A data card with a Universal Serial Bus (USB) plug, comprising:

a housing including a housing antenna contact that is provided on an end portion of the housing, wherein the housing antenna contact is electrically connected with a circuit in the housing; and

a cap, wherein a data card antenna is disposed in the cap, the cap further has at least one cap wing extending from an opening, a cap antenna contact is provided on the at least one cap wing, and the cap antenna contact is electrically connected with the data card antenna in the cap;

wherein the cap is relatively fixed to a bottom end of the housing, and the cap antenna contact is electrically connected with the housing antenna contact;

wherein an interface end guide groove is disposed near a USB interface end on the housing, and a bottom end guide groove is disposed near the bottom end of the housing;

an end of the interface end guide groove towards the USB interface is open, and an opposite end of the interface end guide groove is closed;

an end of the bottom end guide groove towards the bottom end is open, and an opposite end of the bottom end guide groove is closed after traveling across the housing antenna contact; and

the cap antenna contact is configured to freely slide along the groove in the interface end guide groove and the bottom end guide groove.

2. The data card according to claim 1, wherein an opening end of the cap has enough space for accommodating a USB interface of the data card.

3. The data card according to claim 1, wherein the cap antenna contact is a cone, a hemisphere, a column, or a domed column.

4. A data card with a Universal Serial Bus (USB) plug, comprising:

a housing including a housing antenna contact that is provided on an end portion of the housing, wherein the housing antenna contact is electrically connected with a circuit in the housing; and

a cap, wherein a data card antenna is disposed in the cap, the cap further has at least one cap wing extending from an opening, a cap antenna contact is provided on the at least one cap wing, and the cap antenna contact is electrically connected with the data card antenna in the cap, wherein the cap is relatively fixed to a bottom end of the housing, and the cap antenna contact is electrically connected with the housing antenna contact;

wherein a housing guide groove is further disposed on the housing, the housing guide groove extends along a long axis of the housing, two ends of the housing guide groove are closed, the housing antenna contact is located at one end of the housing guide groove near the bottom end; and

wherein the cap is disposed with two cap wings opposite to each other, the cap antenna contact is disposed on one of the cap wings, the cap antenna contact is configured to slide along the housing guide groove, but is not configured to depart from the housing guide groove.

5. The data card according to claim 4, wherein:

a same second guide groove is also disposed on a side opposite to a side of the housing disposed with the guide groove;

a second cap antenna contact or a bump with a shape similar to that of the cap antenna contact is disposed on the cap wing opposite to the cap wing disposed with the cap antenna contact; and

the second cap antenna contact or the bump with a shape similar to that of the cap antenna contact is configured to slide along the second guide groove, but is not configured to depart from the second guide groove.

6. The data card according to claim 4, wherein when the cap antenna contact slides to an end of the housing guide groove, the cap is configured to rotate with the cap antenna contact as an axis, so as to dock with the housing.

7. The data card according to claim 4, wherein the opening of the cap has enough space for accommodating a USB interface of the data card.

8. The data card according to claim 4, wherein the cap antenna contact is a cone, a hemisphere, a column, or a domed column.

9. A data card with a Universal Serial Bus (USB) plug, comprising:

a housing including a housing antenna contact that is provided on an end portion of the housing, wherein the housing antenna contact is electrically connected with a circuit in the housing; and

a cap, wherein a data card antenna is disposed in the cap, the cap further has at least one cap wing extending from an opening, a cap antenna contact is provided on the at least one cap wing, and the cap antenna contact is electrically connected with the data card antenna in the cap, wherein the cap is relatively fixed to a bottom end of the housing, and the cap antenna contact is electrically connected with the housing antenna contact;

wherein an interface end guide groove is disposed near a USB interface end on the housing, and a bottom end guide groove is disposed near the bottom end;

either end of the interface end guide groove is connected with another communication guide groove biasing against the interface end guide groove and the bottom end guide groove, and an opposite end of the interface end guide groove is closed;

an end of the bottom end guide groove away from the housing antenna contact is connected with the communication guide groove, and an opposite end of the bottom end guide groove is closed after traveling across the housing antenna contact; and

the cap antenna contact is configured to freely slide along the groove in the interface end guide groove, the communication guide groove, and the bottom end guide groove, but the cap antenna contact is not configured to depart from any of the communication guide groove, or the bottom end guide groove.

10. The data card according to claim 9, wherein the communication guide groove is of an arc shape or a multi-curve shape.

11. The data card according to claim 9, wherein the opening of the cap has enough space for accommodating a USB interface of the data card.

12. The data card according to claim 9, wherein the cap antenna contact is a cone, a hemisphere, a column, or a domed column.
