Description

Technical Field

[0001] This utility model belongs to the field of connector technology, and in particular relates to a connector for battery power lines. Background Technology

[0002] With the development of lithium battery technology, more and more devices on the market can be miniaturized by electric drive. The devices are becoming more and more dependent on the development of battery technology. In the production process of lithium batteries, wire harnesses need to be connected in series to form a power supply combination. At the end of the power line that connects to the outside world, connectors are usually used to help the power supply combination complete the electrical connection with the device.

[0003] The connectors used in current power cords mainly use a standard interface on one end and are used to fix the power cord harness on the other end. Most common harness fixing methods use a cover plate with a snap-fit ​​structure to fix the harness. The connectors here mostly use a simple snap-fit ​​structure, which has poor stability and is prone to the risk of the harness falling off in some high-movement equipment. Utility Model Content

When the wire harness to be connected is inserted into the cable cavity, the flip cover 200 is deflected and pressed onto the wire harness.

[0031] Specifically, the flip cover 200 includes a cover 210 and two sets of parallel partitions 220. An inner slot 202 is formed between the two sets of partitions 220. An upper wire harness slot 201 is provided on the outer side of the two sets of partitions 220. The cable cavity is provided with a central ridge 110, which divides the cable cavity into two sets of lower wire harness slots 101. The upper wire harness slot 201 and the lower wire harness slot 101 correspond one-to-one and serve as the fixing area of ​​the battery power harness. The public interface 300 is a suitable connector selected by those skilled in the art as needed, and is not limited to the connector structure given in this application.

[0032] The flip cover 200 is provided with an inner slot 202, and the central ridge 110 is provided with a limiting plate 120 that is adapted to the inner slot 202. Both ends of the limiting plate 120 are arc-shaped structures. When the flip cover 200 is flipped and pressed onto the cable, the limiting plate 120 is inserted into the inner slot 202.

[0033] The locking tongue unit 130 includes a locking plate 131, an upper locking tongue 132, a lower locking tongue 133, and an elastic rod 134. The flip cover plate 200 is provided with an inner locking groove 203 and an outer locking groove 204. The inner locking groove 203 and the outer locking groove 204 have a stepped structure. The outer locking groove 204 includes an upper limit area and a lower limit area. The upper limit area and the lower limit area have a stepped structure. When the upper locking tongue 132 is engaged with the inner locking groove 203, the locking plate 131 is simultaneously engaged with the upper limit area and the lower limit area. The lower locking tongue 133 is engaged with the upper limit area.

[0034] The locking tongue unit 130 is elastically connected to the central ridge 110. During the process of the flip cover 200 deflecting and pressing against the cable cavity, the flip cover 200 pushes out the locking tongue unit 130. When the flip cover 200 deflects parallel to the cable cavity, the upper locking tongue 132 and the lower locking tongue 133 are engaged in the inner locking groove 203 and the outer locking groove 204.

[0035] In this embodiment, a power terminal is provided in the lower wire harness groove 101. After the wire harness is stripped, it is arranged in the lower wire harness groove 101 and connected to the power terminal. The power terminal is electrically connected to the electrode plate of the public interface 300 connector. A pressure strip 250 is provided in the upper wire harness groove 201. After pressing, the pressure strip 250 generates additional holding force to tightly hold the wire harness against the power terminal and inside the power terminal.

[0036] In this application, the upper locking tongue 132 and the lower locking tongue 133 form a cross T-shaped structure. The vertically arranged upper locking tongue 132 and lower locking tongue 133 are adapted to the inner locking groove 203 and the outer locking groove 204, thereby improving the connection strength between the flip cover plate 200 and the connector base 100. At the same time, during the locking process, the locking tongue unit 130 uses an elastic linkage mechanism to improve the convenience of the overall structure assembly process, thus improving the ease of assembly while satisfying the fixing effect.

[0037] As a preferred embodiment of this embodiment, the inner slot 202 is further provided with a driving block 230. During the deflection of the flip cover plate 200, the driving block 230 contacts and connects with the upper locking tongue 132 of the locking tongue unit 130 and pushes the locking tongue unit 130 away from the central ridge 110. The end face of the driving block 230 that contacts and connects with the locking tongue unit 130 is a beveled structure.

[0038] The upper locking tongue 132 is arranged parallel to the central ridge 110 at the top of the locking plate 131, and the lower locking tongue 133 is arranged perpendicular to the central ridge 110 on the side wall of the locking plate 131. The upper locking tongue 132 and the lower locking tongue 133 form a T-shaped structure, which will engage in the inner locking groove 203 and the outer locking groove 204 after the locking tongue unit 130 is reset.

[0039] The central ridge 110 is provided with a sliding groove 102; the portion of the locking plate 131 away from the upper locking tongue 132 slides in the sliding groove 102, and a guide sliding hole is provided in the sliding groove 102.
