Description

Battery connector and battery for protection circuit system

technical field

The invention relates to a battery connector and a battery of an electronic device, in particular to a battery connector and a battery for protecting a circuit system.

Background technique

Please refer to Figures 1 and 2. General electronic device, such as mobile phone 10 shown in Figure 1 has a combination groove 12 for accommodating battery 11; Battery 11 has a plurality of electrical connection terminals 111; The plurality of electrical connection terminals 111 correspond to the electrical connection terminals 13 having elasticity. One ends of the plurality of terminals 13 respectively protrude from the plurality of slot holes 122 combined with the bottom wall 121 of the slot 12 . When the battery 11 is accommodated in the coupling slot 12 , the multiple terminals 13 of the battery connector are in elastic contact with the multiple terminals 111 of the battery respectively, so as to achieve the function of electrical connection. The plurality of terminals 13 and the plurality of terminals 111 have a corresponding power terminal (BT+), two signal terminals (SCL, SDA) and a grounding terminal GND, as shown in FIG. 2 .

When the battery 11 is inserted into the coupling slot 12, the corresponding grounding terminals (GND) of the battery 11 and the battery connector must be in contact first, so that the electronic components on the electronic device will work normally. If the two corresponding power supply terminals (BT+) are contacted first, the electronic device will not work normally, and even the electronic parts of the electronic device will be damaged.

China Taiwan Patent Announcement No. 347932 discloses a surface contact connector with a plurality of terminals for contacting the connection surface of the connection object and electrically connecting with the connection object; wherein the aforementioned connection object is a battery assembly, and the aforementioned terminals are formed by The terminal for power supply, the terminal for grounding and the terminal for signal are constituted, and the protruding amount of the contact part of the above-mentioned terminal for grounding is the largest, the protruding amount of the contact part of the terminal for power is the second largest, and the contact part of the terminal for signal is the second largest. The amount of protrusion is minimal.

In the above-mentioned Taiwan patent, under normal circumstances, although the grounding terminal of the connector can first contact the grounding terminal of the battery, the design of the battery connector of each electronic device is not the same, and the difference in mechanism will cause the battery to be grounded. The difference in insertion angle, for example, when the battery is tilted at an angle, so that the battery and the power terminal (BT+) of the battery connector have a closer distance and contact with the two power terminals (GND) earlier, it will still cause the electronic device to work abnormal, and even cause damage to the electronic parts of the electronic device.

Contents of the invention

In order to overcome the defect that the design of the battery connector and battery of the known circuit system cannot ensure that the grounding terminals of the two contact first, the present invention provides a battery connector and battery for protecting the circuit system. The invention can ensure that the battery connector and the grounding terminal of the battery are in contact first, and make the circuit system safer when electrically connecting the battery without causing abnormal operation of the system or damage to electronic parts.

The technical solution adopted by the present invention is: a battery connector used to protect the circuit system, used for electrical connection with the battery, the connector includes a plurality of terminals elastically protruding from the slot holes, and the plurality of terminals include terminals for power supply and a grounding terminal, which is characterized in that: the terminals on both outer sides of the plurality of terminals are grounding terminals, and the contact portion of the two grounding terminals has a longer protrusion than the contact portion of other terminals of the plurality of terminals , when the connector is electrically connected to the battery by the plurality of terminals, the ground terminals of the battery and the connector are first contacted.

The present invention also proposes a battery, including a plurality of terminals, the plurality of terminals include terminals for power supply and terminals for grounding, wherein the terminals on both outer sides of the plurality of terminals are terminals for grounding.

Detailed ways

Please refer to Figure 3. The embodiment of the battery connector used to protect the circuit system of the present invention is described as follows by taking the mobile phone 20 as an example: a mobile phone 20 has a coupling groove 22 for accommodating the battery 21; the coupling groove 22 is combined with a battery connector, and the connector has multiple Terminal 23. The elastic contact portions at one end of the plurality of terminals 23 respectively protrude from the plurality of slot holes 221 , 222 , 223 , 224 , 225 combined with the bottom wall 220 of the slot 22 . The present invention mainly makes the terminals on both sides of the plurality of terminals 23 of the connector all be grounding terminals (GND) 231, 232, while the other terminals are respectively power supply terminals (BT+) 233 and signal terminals (SCL, SDA). ) 234, 235; In this embodiment, the power supply terminal (BT+) 233 is placed in the center, as shown in Figures 4, 5A, and 5B. The contact parts of the grounding terminals 231, 232 on both sides of the connector of the present invention have a longer protrusion than the contact parts of the power supply terminals 233 and signal terminals 234, 235, as shown in Figure 5A; and the grounding terminals can be further used The width of the contact portion of 231, 232 is larger than the width of the power supply terminal 233 and the signal terminals 234, 235, as shown in FIG. 5B.

Please refer to Figure 3. The battery 21 of the embodiment of the present invention has terminals 24 corresponding to the plurality of terminals 23 of the connector; wherein the two outer sides of the plurality of terminals 24 are terminals 241 and 242 for grounding respectively, and the other terminals are respectively power terminals (BT+) 243 and signal terminals 244, 245; the power supply terminal (BT+) 243 is placed in the center, as shown in FIG.

In the present invention, the terminals on both outer sides of the corresponding terminals of the connector and the battery are grounding terminals, and the grounding terminals of the connector have relatively protruding contact parts, and the power supply terminals of the two are placed in the center. , and the power supply terminal has a short contact portion, so no matter which side the battery tilts to contact the connector, at least one ground terminal of the battery will first contact at least one ground terminal of the connector, and then the two power supply terminals The terminal and the signal terminal are in contact; since the contact portion of the power terminal of the connector is shorter than that of the ground terminal and is placed between the two ground terminals, the battery power terminal will not contact the battery connector before the ground terminal Corresponding terminals, so it can ensure that the grounding terminals of the battery and the connector are in contact first, so that the circuit system is safer when connecting the battery, and it will not cause the system to work abnormally or damage the electronic components of the system.
