DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Please refer to FIG. 1 and FIG. 2. A battery connecting apparatus 100 according to the present invention is illustrated. The battery connecting apparatus 100 includes a housing 10 which has a receiving cavity 110 with an inclined opening 120 at an end thereof for receiving a battery therein, a base 20 shaped for sealing the opening 120, and a connector 30 mounted on the base 20 with a lower portion thereof extending below the base through a assembling hole 211 defined in the base 20 for connecting with a power supply circuit (not shown) of the notebook computer and an upper portion thereof supported by the base 20 for connecting with the battery (not shown).
With reference to FIG. 3, the base 20 defines a recess 210 in a top surface thereof. The recess 210 has a bottom wall serving as a supporter 212 and two sidewalls at two opposite sides thereof. The assembling hole 211 is provided through the supporter 212 to be in communication with the recess 210. Each sidewall of the recess 210 has a portion extending into the recess 210 to form a base sliding rail 213. Accordingly, a base sliding groove 214 is defined between the base sliding rail 213 and the supporter 212. The base 20 further has a latching hole 217 which is disposed in the top surface thereof and behind the assembling hole 211.
Please refer to FIG. 4 and FIG. 5. The connector 30 includes an insulating body 31 and a plurality of contacts 32 disposed in the insulating body 31.
With reference to FIG. 5, a lower portion of the insulating body 31 is shaped as a tetragon prism, which can be inserted into the assembling hole 211 of the base 20 and can laterally slide in the assembling hole 211 only from front to rear. An upper portion of the insulating body 31 forms two connector sliding rails 312, which are disposed at two opposite sides of the insulating body 31 for sliding along and resting in the base sliding grooves 214. Above the two connector sliding rails 312, two retainers 313 are disposed, which are integrally formed at the two opposite sides of the insulating body 31, thereby defining two connector sliding grooves 314 between the two connector sliding rails 312 and the two retainers 313 (the right connector sliding groove not shown). The connector sliding grooves 314 are adapted to retain the base sliding rails 213 therein. A latching arm 316 is integrally formed on the rear side of the insulating body 31 and extending rearward. The latching arm 316 has a hook 317 formed at the free end thereof. The upper portion of the insulating body 31 further provides a plate 315 which is integrally formed on the front side of the insulating body 31 and laterally arranged in the same plane with the connector sliding rails 312.
With reference to FIG. 4 and FIG. 5 again, the insulating body 31 vertically defines a plurality of contact receiving holes 320 therein for respectively vertically holding the contacts 32. The upper portions of the contacts 32 are used for electrically connecting the battery, and the lower portions of the contacts 32 are used for electrically connecting the power supply circuit of the notebook computer.
With reference to FIGS. 6–9, the assembling procedure of the battery connecting apparatus 100 includes three steps. Firstly, the lower portion of the connector 30 is inserted into the assembling hole 211 of the base 20 and the two connector sliding rails 312 of the connector 30 are respectively supported on the supporter 212 of the base 20 (shown in FIG. 6) in a removable position where the connector 30 is removable from the base 20. Next, the connector 30 received in the assembling hole 211 is slid rearwards, during which the two connector sliding rails 312 of the connector 30 respectively slide along the two base sliding grooves 214, and the two base sliding rails 213 of the base 20 respectively guide the two connector sliding grooves 314 (shown in FIG. 9), until the connector 30 is latched in an assembled position where the hook 317 of the latching arm 316 is latched to the latching hole 217 (shown in FIGS. 7 and 8). Finally, the base 20 together with the connector 30 assembled thereon is inserted in the receiving cavity and seals the opening 120 of the insulating housing 10 (shown in FIG. 1).
As mentioned above, with providing a sliding engagement mechanism between the base 20 and the connector 30, the connector 30 can slide between the removable position where the connector 30 is removable from the base 20 and the assembled position where the connector 30 is assembled with the base 20. Furthermore, with providing a latching mechanism between the base 20 and the connector 30, the connector 30 can be latched in the assembled position. As can be seen, these sliding engagement mechanism and latching mechanism can certainty and effectively simplifies the assembling procedure of the battery connecting apparatus 100. According to another aspect, the connector 30 and the base 20 are connected by the sliding engagement mechanism and the latching mechanism disposed on themselves. No additional part is needed. Parts of the battery connecting apparatus 100 are thus minimized.
