BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention generally relates to an electrical connecting module and an electrical connecting assembly and, more particularly, to an electrical connecting module for a jacket of a handheld electronic device and an electrical connecting assembly for the jacket and the handheld electronic device.

2. Description of the Related Art

With the continuous improvement of semiconductor technology, new kinds of handheld electronic devices, such as handheld computers, handheld game consoles, mobile phones, e-book readers, smart phones, tablets or phablets, are put into the consumer market rapidly and frequently. By the digital content installed inside, these handheld electronic devices can provide various functions such as communication, document processing and entertainment.

Due to the increased functions of such a handheld electronic device, the handheld electronic device is often used for a longer duration of time, leading to the development of a variety of jackets of the handheld electronic device, such as the one with a cooling function which allows the heat of the handheld electronic device to be properly dissipated during the use of said device (such as during the game play). Such a jacket can be seen in China Patent No. 204028752U.

When a conventional jacket with a cooling function is in use, a fan inside the jacket requires DC power for operations. Although the DC power can be provided through a transmission port and a transmission cable (such as micro USB or Lightening USB) of the handheld electronic device, the handheld electronic device is often designed with a single transmission port in order to reduce the volume of said device. However, the single transmission port can only be used for data transmission purposes or charging purposes at the same time. In words, when the transmission port of the handheld electronic device is used to power the jacket, data cannot be transmitted through the transmission port at the same time, and the original charging function of said device is affected. To solve the problem, different cables may be used where one of which is used to power the jacket and the other one is used to provide data transmission function or charging function of the handheld electronic device. However, the use of multiple cables and the difference in the lengths of the cables may cause troubles to the user. Therefore, it is necessary to provide a solution for powering the jacket while providing data transmission function or charging function of the handheld electronic device.

DETAILED DESCRIPTION OF THE INVENTION

The term “transmission line” used hereinafter in the present invention refers to a transmission medium that can connect to a transmission port of a handheld electronic device in order to supply the power to or provide data transmission function for said device, such as a micro USB to USB cable or a lightning USB cable. As shown in FIG. 1, the transmission line “T” includes one end forming a connecting plug T1 for the handheld device and another end forming a USB plug T2. Each of the connecting plug T1 and the USB plug T2 includes a plurality of conductive terminals, which can be appreciated by the persons ordinarily skilled in the art.

Please refer to FIG. 1, an electrical connecting module for a jacket of a handheld electronic device according to a first embodiment of the present invention includes a body 1 and a conducting wire 2. The body 1 can be made of a flexible, insulating material such as plastic or resin. The body 1 may include a retaining hole 11 and a plurality of electrical contact 12. The retaining hole 11 is adapted to partially receive the connecting plug T1 of the transmission line “T.” The plurality of electrical contact 12 may be located at an end of the body 1, and the conducting wire 2 is electrically connected to the plurality of electrical contact 12. As an example, the conducting wire 2 may be directly connected to the plurality of electrical contact 12 or coupled to the electrical contact 12 via a conducting path.

In this embodiment, the body 1 shown in FIG. 1 may include front and rear surfaces 13 spaced from each other along a length direction, top and bottom surfaces spaced from each other along a height direction perpendicular to the length direction, and two lateral surfaces spaced from each other along a width direction perpendicular to the length and height directions. However, the length, height and width directions may not be perpendicular to each other. The retaining hole 13 extends through the front and rear surfaces 13. The plurality of electrical contact 12 may be located at two opposite sides of the retaining hole 11 respectively adjacent to the two lateral surfaces, but is not limited thereto. One end of the conducting wire 2 is connected to the body 1, and another end of the conducting wire 2 is connected to a connector 21, such as a USB connector. A fixing portion 22 (such as a groove) is formed on an outer surface of the conducting wire 2 for receiving the transmission line “T,” thus preventing damage to the transmission line T resulting from frequent bending of said line “T.” Therefore, the transmission line T and the conducting wire 2 can be assembled together.

Please refer to FIG. 2, an electrical connecting module for a jacket of a handheld electronic device according to a second embodiment of the present invention is shown.

In this embodiment, the body 1 may include a dust cover 17′ to prevent accumulation of dust in the receiving channel 14. The dust cover 17′ has one end that is connected with the body 1 in a bendable manner, so that the dust cover can be bent in order to be received in or disengaged from the receiving channel 14.

Please refer to FIG. 6, an electrical connecting module for a jacket of a handheld electronic device according to a fifth embodiment of the present invention is shown. In FIG. 6, the body 1 further includes a second connecting port 18 for insertion of the USB plug T2 of the transmission line “T,” and the second connecting port 18 is electrically connected to the conducting wire 2. Therefore, the conducting wire 2 can deliver power to the connecting plug T1 of the transmission line “T” and the plurality of electrical contacts 12 of the body 1 at the same time. In this regard, a user can plug the USB plug T2 of the transmission line “T” into the second connecting port 18 of the body 1 to power the handheld electronic device and the jacket at the same time.

Please refer to FIGS. 1, 2, 4 and 6, a positioning portion 15 (such as a shoulder) may be formed on the inner periphery of the body 1, and is adapted to abut with the connecting plug T1 of the transmission line “T” so as to securely fix the connecting plug T1 in the retaining hole 11 (as shown in FIG. 4). To provide a reinforced engagement between the transmission line “T” and the body 1, the connecting plug T1 may be fixed in the retaining hole 11 in a press fit manner, and a covering material, such as a thermoplastic sleeve, a resin sleeve, a silicone sleeve or a shell, is used to envelop the body 1 and the transmission line “T” altogether. Alternatively, at least one through-hole 16 may be arranged on the top surface of the body 1 and communicates with the retaining hole 11 as shown in FIGS. 1 and 2. The through-hole 16 may be filled with gel to adhere the body 1 and the connecting plug T1 to each other. As shown in FIGS. 4-6, the through-hole 16′ may be in the form of a countersink, and may be arranged on the top surface of the body 1 and communicates with the retaining hole 11. The through-hole 16′ may include a screwed portion 161′ and a head portion 162′ to be screwed by a screw for engagement of the body 1 and the connecting plug T1. However, the implementation is not taken as a limited sense.
