in the prior art, part of the flashlight is convenient to charge by using a double-end double-electrode battery shown in fig. 7 and is provided with a special flashlight end cover. The double-ended double-electrode battery has an outer shape similar to a conventional dry battery, but has both the positive electrode 15 and the negative electrode 16 at both ends. The battery with double ends and double electrodes is expensive due to the special structure, and the specially-made flashlight end cover in the prior art is not suitable for a common dry battery, so that two conductive pieces on the flashlight end cover are short-circuited when the common dry battery is used, and certain safety risk is caused. Therefore, the utility model provides a charging connection assembly 9, it contains flashlight end cover and battery holder.

Referring to fig. 1 to 4, in the present embodiment, a pen light end cap includes a tail cap 1 for covering a battery slot 6 of a pen light, and a first conductive member 2 and a second conductive member 4 disposed on the tail cap 1; the first conductive member 2 is higher than the second conductive member 4; the tail cover 1 is made of conductive materials, the first conductive piece 2 is electrically connected to the tail cover 1, and the second conductive piece 4 penetrates through the tail cover 1 and is insulated from the tail cover 1; the tail cap 1 can be disposed on the charging dock.

The first conductive piece 2 and the second conductive piece 4 can be electrically connected to two electrodes of the battery, respectively, and the tail cover 1 can be connected to the charging base, so that the tail cover 1 and the second conductive piece 4 are electrically connected to the charging base, respectively. Specifically, a common dry battery is a double-end single electrode, that is, two ends are respectively a positive electrode and a negative electrode, the positive electrode is a protrusion, and the negative electrode is flat. As shown in FIG. 6, when the dry cell is used, the cap of the pen light is abutted against the negative electrode of the dry cell. Because the first conductive piece 2 is higher than the second conductive piece 4, the cathode of the pen lamp can only contact the first conductive piece 2, so the dry battery can not cause short circuit between the first conductive piece 2 and the second conductive piece 4, even if the dry battery is forgotten to be taken out when being used as a power supply, the pen lamp is arranged on the charging base, the short circuit can not be caused, and the pen lamp has good practical significance. When a double-ended double-electrode battery, i.e., a battery having both ends provided with positive and negative electrodes, is used, as shown in fig. 5, a first conductive member 2 and a second conductive member 4 are electrically connected to the positive and negative electrodes of the same end of the battery, respectively.

As shown in fig. 2 and 4, in this embodiment, the first conductive member 2 is a compression spring, an avoidance channel 5 is disposed in the middle, and the second conductive member 4 faces the avoidance channel 5. Specifically, the pressure spring passes through the mounting groove of tail-hood 1 recess lateral wall to be fixed on tail-hood 1, and the bottom of the 1 recess of second conductive piece 4 embedding tail-hood, and from the axial direction, first conductive piece 2 is around the second conductive piece 4, should arrange for tail-hood 1 need not distinguish the direction when using, and also can not bump second conductive piece 4 after the pressure spring is compressed, and the short circuit does not take place for assurance that can be fine.

As shown in fig. 2 and 4, in the present embodiment, an insulating member 3 is disposed between the second conductive member 4 and the tail cover 1, and a groove 26 is disposed between the insulating member 3 and the second conductive member 4. Specifically, the second conductive member 4 protrudes from the bottom of the groove 26, and the protruding portion is located inside the groove 26 and does not protrude out of the groove 26, so that the structure can increase the contact area of the second conductive member 4, which is very practical. And the end of the second conductive member 4 is a compressible elastic structure, so that it can be pressed when abutting against the battery, thereby ensuring the conductive effect.

As is less common in the prior art, in order to facilitate replacement, as shown in fig. 7, the charging connection assembly 9 further includes a connector 17 disposed on an electrode of the double-ended double-electrode battery for heightening one of the two electrodes at the end of the battery. Specifically, the connector 17 is disposed at one end of the two-terminal two-electrode battery such that the positive electrode and the negative electrode of the same end are higher and lower, so that the two-terminal two-electrode battery with two planar ends can be fitted to the pen lamp end cap.

Referring to fig. 8 to 12, in the present embodiment, a battery holder of a pen light is configured to be mounted on a double-ended single-electrode battery 18, which includes: the battery comprises a shell 11, a first contact member 12 which is arranged on the shell 11 and is electrically connected with a first electrode 24 of the battery, and a second contact member 13 which is arranged on the shell 11 and is electrically connected with a second electrode 23 of the battery, wherein the first contact member 12 is annular, and the second contact member 13 is positioned in the middle of the annular first contact member 12 and penetrates through the first contact member 12. Specifically, the first contact 12 and the second contact 13 can conduct electricity. The two ends of the double-ended single-electrode battery 18 are respectively a positive electrode and a negative electrode, and are electrically connected to the first contact member 12 and the second contact member 13 through conductive members. The case 11 is disposed at one end of the double-ended single-electrode cell 18, and covers the electrode at the one end, so that the double-ended single-electrode cell 18 has a structure in which one end is a single electrode and one end is a double electrode. As shown in fig. 13, if two battery holders are installed on one double-end single-electrode battery 18 at the same time, a double-end double-electrode structure can be realized, so that the manufacturing cost of the double-end double-electrode battery is greatly saved, and the practical significance is good.

As shown in fig. 11 and 12, in the present embodiment, the first contact 12 has a plate shape, and the second contact 13 has a circular cross section. Specifically, the first contact piece is a circular ring-shaped piece having a certain thickness, i.e., a diameter in the radial direction is larger than a height in the axial direction, and the second contact piece 13 is a cylindrical body.

As shown in fig. 11 and 12, in the present embodiment, the second contact 13 is located at the center of the circular ring of the first contact 12 and extends in the axial direction of the first contact 12 such that the end surface of the second contact 13 is higher than the end surface of the first contact 12. Specifically, the height only indicates that the end surface of the second contact 13 protrudes from the plane where the first contact 12 is located. As shown in fig. 4, the first contact 12 and the second contact 13 are downward with respect to the battery, and therefore the end face of the second contact 13 is higher than the end face of the first contact 12, that is, the end face of the second contact 13 is below the first contact 12. In fig. 10, the first contact 12 and the second contact 13 are upward with respect to the battery, and therefore the end face of the second contact 13 is higher than the end face of the first contact 12, that is, the end face of the second contact 13 is above the first contact 12.

As shown in fig. 9, 10, and 12, in the present embodiment, the housing 11 has a tubular portion 14 that is fitted over the second contact 13. Specifically, the first contact member 12 has a circular ring shape, the second support member is located at the center of the circular ring, and the tubular portion 14 is sleeved on the second contact member 13, so that the first contact member 12 and the second contact member 13 are isolated by the tubular portion 14. The second contact 13 can be effectively prevented from being electrically connected with the first contact 12 due to bending in the using process, and the short circuit can be prevented. And the creepage distance between the second contact piece 13 and the first contact piece 12 is increased, and the safety of the battery bracket is greatly improved. And the diameter of the tubular part 14 is matched with the groove 26 arranged between the insulating part 3 and the second conductive part 4, when the battery bracket is matched with a pen lamp end cover for use, the first conductive part 2 abuts against the first contact part 12 and is electrically connected, the tubular part 14 and the second contact part 13 penetrate through the first conductive part 2, and the tubular part 14 is inserted into the groove 26, so that the second conductive part 4 and the second contact part 13 abut against and are electrically connected. When the two circuits are electrically connected, the two circuits can be well ensured not to interfere with each other, and the method has good practical significance. And the end of the second contact member 13 is a compressible elastic structure, so that it can be pressed when abutting against the conductive member of the end cap, to ensure the conductive effect.

As shown in fig. 10 and 12, in the present embodiment, the housing 11 has a cylindrical cavity, and a first supporting portion 20 which is used to connect a side wall of the cavity and the tubular portion 14 and is arranged along a radial direction of the cavity. Specifically, the tubular portion 14 separates the first contact member 12 and the second contact member 13 from the radial direction, and the first contact member 12 and the second contact member 13 are respectively located on both sides of the first supporting portion 20, so that the first supporting member separates the first contact member 12 and the second contact member 13 from the axial direction, ensuring the insulation strength between the first contact member 12 and the second contact member 13.

As shown in fig. 10 and 12, in the present embodiment, the housing 11 further has a limiting groove 19 located on the side wall of the cavity and adjacent to the first supporting portion 20, and a second supporting portion 21 located on the side wall of the cavity and arranged along the radial direction of the cavity, a gap for placing the second contact element 13 is provided between the first supporting portion 20 and the second supporting portion 21, and the first contact element 12 can be received in the limiting groove 19; the second contact member 13 is a geometric body having an inverted "T" shape in cross section. . Specifically, the second contact 13 has a columnar portion in a cylindrical shape passing through the second tubular portion 14, and a third support portion in a square sheet shape at one end of the columnar portion. The columnar portion does not protrude from the middle of the tubular portion 14, i.e., the end surface of the columnar portion is flush with the end surface of the tubular portion 14 or slightly lower than the end surface of the tubular portion 14. The upper end surface of the third support portion is supported by the first support portion 20, and the lower end surface of the third support portion is supported by the second support portion 21, so that the second contact 13 cannot swing. The first contact member 12 is far away from one side of the second contact surface, an annular limiting groove 19 is formed at the joint of the first contact member 12 and the side wall of the accommodating cavity, and the first contact member 12 can be embedded into the limiting groove 19 so as to be fixed on the shell 11.
