Description
Technical Field
[0001] The present application belongs to the technical field of battery connectors, and in particular relates to a thin and lightweight battery connector that is easy to process. Background Art
[0002] As an important component of storage batteries, battery connectors have been widely used in the battery field. The battery connector includes a current transmission pin and a signal transmission pin connected to the battery, and the current transmission pin is welded with a current wire to connect the battery, and the signal transmission pin is welded with a signal wire to connect the battery. In traditional technology, in order to meet the welding surface of the current transmission pin and the current wire, and the signal transmission pin and the signal wire, welding wire cups are usually set at the ends of the current transmission pin and the signal transmission pin respectively. When welding, the current wire and the signal wire need to be placed in the welding wire cups respectively before welding. In this way, on the one hand, the operator needs to place the current wire and the signal wire in the welding wire cups first when welding, which makes the welding process more complicated; on the other hand, the setting of the welding wire cup will occupy a large vertical space, thereby increasing the vertical height of the battery connector, which is not conducive to the miniaturization of the battery connector. At the same time, the use of welding wire cups for welding will also increase the processing cost of the battery connector.
[0003] In addition, in order to enhance the signal transmission capability of the signal transmission pins, the signal transmission pins are usually first connected in series by welding and then connected to the signal line through a welding cup, which further increases the processing difficulty of the battery connector. Utility Model Content
[0004] The present application provides a thin and lightweight battery connector that is easy to process, so as to solve the technical problems of the traditional battery connector being too large in size and having complex welding.
[0005] The technical solution adopted in this application is:
[0006] A thin and lightweight battery connector that is easy to process comprises a connector body and a circuit board. The connector body comprises a current transmission part and a signal transmission part. The current transmission part comprises an outwardly extending current transmission needle. The signal transmission part comprises an outwardly extending signal transmission needle. The circuit board is provided with a current channel and a signal channel connected to a battery. The current transmission needle and the signal transmission needle are both welded to the circuit board. The current transmission needle and the signal transmission needle are respectively connected to the battery through the circuit board.
[0007] The thin and light battery connector that is easy to process described in this application also includes the following additional technical features:
[0008] The number of the signal transmission needles is multiple, and the signal channel includes multiple independent signal transmission pathways and signal transmission lines respectively connected to the signal transmission pathways and the battery, and the signal transmission pathway has a first welding end welded to the signal transmission needle.
[0009] The number of the signal transmission pins is an even number and every two of the signal transmission pins form a signal transmission group. The signal transmission pins of each signal transmission group are welded to the same signal transmission path, and the signal transmission pins of each signal transmission group are connected in series through the signal transmission path.
[0010] There are multiple current transmission needles, and the current channel includes a current transmission path and current transmission lines respectively connected to the current transmission path and the battery. The current transmission path has a second welding end welded to the current transmission needle.
[0011] The connector body includes a first plug-in slot, and the current transmission portion includes a first mounting shell sleeved on the outside of the current transmission pin, and the first mounting shell is interference-fitted with the first plug-in slot to fix the current transmission pin to the first plug-in slot.
[0012] The first mounting shell and the first plug-in slot are both multiple in number. The first mounting shell includes a first abutting portion located at the first plug-in slot and a first extending portion located outside the first plug-in slot. Epoxy resin is poured between the first mounting shell and the first plug-in slot.
[0013] The connector body includes a second plug-in slot, and the signal transmission portion includes a second mounting shell sleeved on the outside of the signal transmission pin, and the second mounting shell is interference-fitted with the second plug-in slot to fix the signal transmission pin to the second plug-in slot.
[0014] The second mounting shell and the second plug-in slot are both multiple in number. The second mounting shell includes a second abutment portion located at the second plug-in slot and a second protruding portion located outside the second plug-in slot. The multiple second protruding portions are connected by epoxy resin.
[0015] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:
[0016] 1. The battery connector of the present application is provided with a connector body and a circuit board, wherein the current transmission pin and the signal transmission pin extending out of the connector body are respectively welded to the circuit board, and are respectively connected to the battery through the current channel and the signal channel. It is not necessary to provide welding wire cups at the ends of the current transmission pin and the signal transmission pin to complete the welding of the current transmission pin and the signal transmission pin to the circuit board respectively. The alignment of the current transmission pin, the signal transmission pin and the circuit board is relatively simple, which reduces the difficulty of welding.
[0017] 2. As a preferred embodiment of the present application, the number of the signal transmission needles is multiple, the signal channel includes multiple independent signal transmission paths and signal transmission lines respectively connected to the signal transmission paths and the battery, and the signal transmission path has a first welding end welded to the signal transmission needle. With such a configuration, when welding the signal transmission needle, the signal transmission needle can be attached to the first welding end for welding. Since the thickness of the circuit board is much smaller than the height of the welding wire cup, such a welding method greatly reduces the vertical height of the battery connector. Compared with the method of setting the welding wire cup at the end of the current transmission needle and the signal transmission needle, the battery connector of the present application has been greatly reduced in vertical height, which is conducive to the flattening and miniaturization of the battery connector; in addition, the number of signal transmission needles is multiple, and the circuit board is provided with a signal transmission path matching the number of signal transmission needles, so that a single circuit board can meet the signal transmission requirements of multiple signal transmission needles and batteries, further improving the miniaturization of the battery connector.

With such a configuration, when welding the current transmission needle, the current transmission needle can be attached to the second welding end for welding. Since the thickness of the circuit board is much smaller than the height of the welding wire cup, such a welding method greatly reduces the vertical height of the battery connector. Compared with the method of setting the welding wire cup on the current transmission needle and the end of the current transmission needle, the battery connector of the present application has been greatly reduced in vertical height, which is conducive to the flattening and miniaturization of the battery connector.

[0034] like Figure 1 , Figure 2As shown, a thin and lightweight battery connector that is easy to process includes a connector body 5 and a circuit board 3. The connector body 5 includes a current transmission part 1 and a signal transmission part 2. The current transmission part 1 includes an outwardly extending current transmission needle 11, and the signal transmission part 2 includes an outwardly extending signal transmission needle 21. The circuit board 3 is provided with a current channel and a signal channel connected to the battery. The current transmission needle 11 and the signal transmission needle 21 are both welded to the circuit board 3, and the current transmission needle 11 and the signal transmission needle 21 are respectively connected to the battery through the circuit board 3.
[0035] The battery connector of the present application is provided with a connector body 5 and a circuit board 3, wherein the current transmission pin 11 and the signal transmission pin 21 extending out of the connector body 5 are respectively welded to the circuit board 3, and are respectively connected to the battery through the current channel and the signal channel on the circuit board 3. There is no need to set welding wire cups at the ends of the current transmission pin 11 and the signal transmission pin 21 to complete the welding of the current transmission pin 11 and the signal transmission pin 21 to the circuit board 3 respectively. The alignment of the current transmission pin 11, the signal transmission pin 21 and the circuit board 3 is relatively simple, which reduces the difficulty of welding.
[0036] As a preferred implementation of the present application, Figure 1 , Figure 2 As shown, the number of the signal transmission pins 21 is multiple, and the signal channel includes multiple independent signal transmission paths and signal transmission lines 6 respectively connected to the signal transmission paths and the battery, and the signal transmission path has a first welding end welded to the signal transmission pin 21. In this way, when welding the signal transmission pin 21, the signal transmission pin 21 can be attached to the first welding end for welding. Since the thickness of the circuit board 3 is much smaller than the height of the welding cup, such a welding method greatly reduces the vertical height of the battery connector. Compared with the method of setting the welding cup at the end of the current transmission pin 11 and the signal transmission pin 21, the battery connector of the present application has been greatly reduced in vertical height, which is conducive to the flattening and miniaturization of the battery connector; in addition, the number of the signal transmission pins 21 is multiple, and the circuit board 3 is provided with a signal transmission path matching the number of the signal transmission pins 21, so that a single circuit board 3 can meet the signal transmission requirements of multiple signal transmission pins 21 and the battery, further improving the miniaturization of the battery connector.
[0037] As a preferred embodiment of this implementation, Figure 1 , Figure 2As shown, the number of the signal transmission pins 21 is an even number and every two of the signal transmission pins 21 form a signal transmission group. The signal transmission pins 21 of each signal transmission group are welded to the same signal transmission path, and the signal transmission pins 21 of each signal transmission group are connected in series through the signal transmission path. Setting two signal transmission pins 21 as a signal transmission group and welding the signal transmission pins 21 of each signal transmission group to a signal transmission path increases the signal transmission strength of the signal transmission pin 21 to the signal transmission path, which helps to improve the transmission sensitivity of the battery connector to the battery signal; in addition, each signal transmission path can realize signal transmission with two signal transmission pins 21, reducing the number of signal transmission paths opened on the circuit board 3, which helps to reduce the manufacturing difficulty of the circuit board 3.
[0038] As a preferred implementation of the present application, Figure 1 , Figure 2 As shown, the number of the current transmission needles 11 is multiple, and the current channel includes a current transmission path and a current transmission line 7 connected to the current transmission path and the battery respectively, and the current transmission path has a second welding end welded to the current transmission needle 11. In this way, when welding the current transmission needle 11, the current transmission needle 11 can be attached to the second welding end for welding. Since the thickness of the circuit board 3 is much smaller than the height of the welding wire cup, this welding method greatly reduces the vertical height of the battery connector. Compared with the method of setting the welding wire cup on the current transmission needle 11 and the end of the current transmission needle 11, the battery connector of the present application has been greatly reduced in vertical height, which is conducive to the flattening and miniaturization of the battery connector.
[0039] As a preferred implementation of the present application, Figure 1 , Figure 2 As shown, the connector body 5 includes a first plug-in slot 4, and the current transmission part 1 includes a first mounting shell 12 sleeved on the outside of the current transmission pin 11, and the first mounting shell 12 is interference-fitted with the first plug-in slot 4 to fix the current transmission pin 11 to the first plug-in slot 4. By setting the first plug-in slot 4, a mounting position is provided for the current transmission pin 11, and the first mounting shell 12 can wrap the current transmission pin 11 on the one hand, thereby playing a certain protective role for the current transmission pin 11, reducing the risk of damage to the current transmission pin 11 due to collision during installation or use; on the other hand, the first mounting shell 12 can be interference-fitted with the first plug-in slot 4 to install the current transmission pin 11 in the first plug-in slot 4, and the current transmission pin 11 can be installed by inserting the first mounting shell 12 equipped with the current transmission pin 11 into the first plug-in slot 4, which greatly reduces the difficulty of installing the current transmission pin 11.
[0040] As a preferred embodiment of this implementation, Figure 1 , Figure 2 As shown, the first mounting shell 12 and the first plug-in slot 4 are both multiple in number, the first mounting shell 12 includes a first abutment portion 121 located at the first plug-in slot 4 and a first extension portion 122 located at the outside of the first plug-in slot 4, and epoxy resin is poured between the first mounting shell 12 and the first plug-in slot 4. Specifically, the connector body 5 also includes a first installation cavity located outside the first plug-in slot 4, and at least a portion of the first extension portion 122 is located in the first installation cavity. After a plurality of first installation shells 12 equipped with current transmission needles 11 are inserted into the first plug-in slot 4, the plurality of first extension portions 122 are located in the first installation cavity. At this time, epoxy resin can be poured into the first installation cavity. During the pouring process, the epoxy resin will also be poured into the gap between the first plug-in slot 4 and the first installation shell 12, thereby sealing the first plug-in slot and preventing external dust, debris, etc. from entering the connector body 5 through the gap between the first installation shell 12 and the first plug-in slot 4. In addition, the epoxy resin can also fix the first installation shell 12 in the first plug-in slot 4, thereby improving the plugging stability of the first installation shell 12.
[0041] As a preferred implementation of the present application, Figure 1 , Figure 2 As shown, the connector body 5 includes a second plug-in slot, and the signal transmission part 2 includes a second mounting shell 22 sleeved on the outside of the signal transmission pin 21, and the second mounting shell 22 is interference fit with the second plug-in slot to fix the signal transmission pin 21 to the second plug-in slot.
[0042] By setting up the second plug-in slot, an installation position is provided for the signal transmission pin 21, and the second mounting shell 22 can wrap the signal transmission pin 21, so as to provide a certain degree of protection for the signal transmission pin 21 and reduce the risk of damage to the signal transmission pin 21 due to collision during installation or use; on the other hand, the second mounting shell 22 can be interference fit with the second plug-in slot to install the signal transmission pin 21 in the second plug-in slot, and the signal transmission pin 21 can be installed in the second plug-in slot by simply inserting the second mounting shell 22 with the signal transmission pin 21 into the second plug-in slot, which greatly reduces the difficulty of installing the signal transmission pin 21.
[0043] As a preferred embodiment of this implementation, Figure 1 , Figure 2As shown, the number of the second mounting shell 22 and the second plug-in slot are both multiple, and the second mounting shell 22 includes a second abutment portion 221 located at the second plug-in slot and a second extension portion 222 located outside the second plug-in slot, and the multiple second extension portions 222 are connected by epoxy resin. Specifically, the connector body 5 also includes a second mounting cavity located outside the second plug-in slot, and at least part of the second extension portion 222 is located in the second mounting cavity. After the multiple second mounting shells 22 equipped with signal transmission pins 21 are inserted into the second plug-in slot, the multiple second extension portions 222 are located in the second mounting cavity. At this time, epoxy resin can be poured into the second mounting cavity, and the viscosity of the epoxy resin is relied on to connect the second extension portions 222 and the connector body 5 as a whole, thereby enhancing the connection strength between the signal transmission portion 2 and the connector body 5.
