Description

Technical Field

[0001] The utility model belongs to the technical field of connectors, and in particular relates to a battery connector with a lock. Background Art

[0002] The battery connector is a very critical component in the electrical system, which plays the role of connecting the battery to the electrical system. The quality of the battery connector is directly related to the stability and safety of the electrical system, so it is very important to choose a high-quality connector. First of all, the battery connector needs to have good conductivity. The battery connector is a channel for current and needs to be able to withstand a large amount of current passing through. Therefore, the conductivity of the connector directly determines the stability of the entire electrical system. A good connector should have the characteristics of low resistance and high conductivity to ensure that the current can pass smoothly.

[0003] Secondly, the battery connector also needs to have good corrosion resistance. Electrical systems are often exposed to moisture, high temperature and chemical erosion, so the connector needs to be able to resist corrosion from these external environments. Good connectors should be made of corrosion-resistant materials, such as copper, aluminum, stainless steel, etc., so that the connector can work stably for a long time. In addition, the battery connector also needs to have good structural strength. The basic principle of the battery connector is to connect the power and signal lines together through a connector composed of a metal conductor and an insulating material. These connectors are usually composed of a steel shell and a copper conductive pin, which has good conductivity and mechanical strength. The insulating material inside the connector can effectively isolate the conductive part to prevent current short circuits and signal interference.

[0004] However, in some specific application scenarios, such as vehicle-mounted battery connectors, they are often frequently subjected to forces such as vibration, impact and pulling. In order to ensure that the connector can still work stably, normally and efficiently under environments such as vibration, impact and pulling, it is necessary to design a battery connector with a lock that can not only pass large currents, but also lock the battery connectors when they are plugged in and paired, to prevent failure during the power supply process due to vibration, impact, pulling and other forces in the application environment, thereby affecting the energy supply of the entire system.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The embodiment of the utility model provides a battery connector with a lock, including a board-end connector and a wire-end connector plugged therewith, specifically:

[0029] like Figures 1 to 4 As shown, in this embodiment, the board-end connector includes a board-end plastic body 1, a board-end power terminal 2 and a board-end grounding plate 3, wherein the board-end plastic body 1 includes a docking portion 101 for plugging with the line-end connector and a fixing portion 102 for fixing to the circuit board inside the battery module, and a plug-in cavity 103 is provided in the docking portion 101, and a guide groove 104 with a lock hole 105 is provided above the plug-in cavity 103. A barb 201 is provided in the middle of the board-end power terminal 2, and is fixed in the board-end plastic body 1 by an insert injection molding process. One end of the board-end power terminal 2 is located parallel to the plug-in cavity 103, and the other end is located outside the board-end plastic body 1, and is vertically bent and tightly attached to the outer end surface of the fixing part 102 to form a power terminal welding foot 202; one end of the board-end grounding plate 3 is embedded in the outer side of the fixing part 102, and the other end is vertically bent and parallel to the outer end surface of the fixing part 102 to form a grounding terminal welding foot 301, so as to facilitate subsequent welding with the circuit board.

[0030] like Figure 3 and Figure 5 As shown, in this embodiment, the wire end connector includes a wire end plastic body 4, a buckling structure 5 matching the lock hole 105 is provided above the plug-in section 401 of the wire end plastic body 4, and a wire end power terminal 6 plugged into the board end power terminal 2 is provided inside the wire end plastic body 4; the wiring section 402 of the wire end plastic body 4 is perpendicular to the plug-in section 401, and is installed with a wire end back cover 7 in a snap-fitting manner to press and fix the wire end power terminal 6 and the cable 9.

[0031] As a preferred embodiment, the buckle structure 5 includes a support portion 501, an elastic arm 502 and a hook 503. The support portion 501 is fixedly arranged above the end of the plug-in section 401 of the wire end plastic body 4. One end of the elastic arm 502 is integrally connected to the support portion 501, and the other end extends toward the wiring section 402 of the wire end plastic body 4 to form a press-unlocking portion 504. The hook 503 is arranged in the middle of the elastic arm 502. The size of the elastic arm 502 matches the guide groove 104, and can be inserted into the wire end connector as the wire end connector is inserted. The wire-end connector slides back and forth along the guide groove 104. When the plug-in section 401 of the wire-end connector is fully inserted into the plug-in cavity 103 of the board-end connector, the hook 503 will bounce upward under the elastic force of the elastic arm 502 and engage with the locking hole 105, thereby locking the connection state between the wire-end connector and the board-end connector. When the wire-end connector needs to be separated from the board-end connector, it is only necessary to press the push-to-unlock portion 504 to make the hook 503 move downward and disengage from the locking hole 105, and then the wire-end connector can be smoothly pulled out.

[0032] Furthermore, the line-end power terminal 6 is L-shaped and is formed by integral stamping of metal sheets. The line-end power terminal 6 includes a plug-in portion 601 located in the plug-in section 401 and a wire clamp portion 603 located in the wiring section 402. The plug-in portion 601 is hollow for the board-end power terminal 2 to be inserted into, and a contact spring 602 is provided inside the plug-in portion 601. The plug-in portion 601 relies on elastic deformation during insertion to ensure that the plug-in portion 601 can form a close contact with the board-end power terminal 2. The side wall of the wire clamp portion 603 adopts an open design and is bent to form a clamping piece 604 to better fix the line-end power terminal 6 to the cable 9.

[0033] Furthermore, in order to make the line-end power terminal 6 be fixed more firmly on the line-end plastic body 4, a fixing hole 403 is also opened through the side wall of the line-end plastic body 4, and a terminal fixing pin 8 is clamped and installed in the fixing hole 403. The terminal fixing pin 8 is located between the plug-in part 601 and the wire clamp part 603 of the line-end power terminal 6, thereby limiting and fixing the line-end power terminal 6 well, ensuring the stability of the connection, preventing the line-end power terminal 6 from loosening after frequent plugging and unplugging, and extending the service life of the connector.

[0034] The above-mentioned embodiments only express the implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
