DETAILED DESCRIPTION

[0040] The technical solution of the present application will be described clearly and completely below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0041] Combine the following Figure 1-Figure 8 , describing the connector provided in the embodiment of the present application, including a box body, a female plug 200, a first elastic member 300 and a male plug 400, a cavity is formed inside the box body, and a window hole 121 is opened on the box body; the female plug 200 is arranged at a position corresponding to the window hole 121 in the cavity; the first elastic member 300 is arranged in the cavity, distributed along the circumference of the female plug 200, and can cause the female plug 200 to translate on a first plane through telescopic deformation, and the first plane is a plane perpendicular to the depth direction of the window hole 121; the male plug 400 is used to connect with the female plug 200 at the window hole 121. In some specific embodiments, the box body includes a base 110 and a top shell 120, the top shell 120 is installed on the base 110 by bolts, the window hole 121 is opened on the side of the top shell 120 away from the base 110, and a cavity is formed between the top shell 120 and the base 110, the base 110 is used to be installed on the battery management system mainboard, the female plug 200 is arranged in the cavity, and the male plug 400 is connected with the female plug 200 to realize the connection between the battery management system mainboard and the slave board. Specifically, the male plug 400 is formed with a convex portion, and the female plug 200 is formed with a groove, and pins are provided on the convex portion and in the groove, and the outer wall of the convex portion cooperates with the inner wall of the groove. When the convex portion is inserted into the groove, the pins contact each other to realize the electrical connection between the battery management system mainboard and the slave board. In some embodiments, the convex portion of the male plug 400 is formed with a conical surface, so that the male plug 400 and the female plug 200 can be quickly aligned. In some specific embodiments, a first groove may be provided on the inner wall of the cavity, and a second groove may be provided on the outer surface of the female plug 200, and the ends of the first elastic member 300 may be respectively clamped in the first groove and the second groove to limit the first elastic member 300 and prevent the first elastic member 300 from moving along the hole depth direction of the window hole 121, so that the female plug 200 can only move on a plane perpendicular to the hole depth direction of the window hole 121. In some specific embodiments, the first elastic member 300 may be a spring or a spring sheet. Preferably, the first spring member is a spring sheet. Figure 8As shown, the spring sheet is S-shaped, the inner end of the spring sheet abuts against the outer surface of the female plug 200, and the outer end of the spring sheet abuts against the inner wall of the cavity. Since the spring sheet is not easy to bend in the width direction (i.e., the hole depth direction of the window hole 121), the female plug 200 is prevented from moving along the hole depth direction of the window hole 121; at the same time, through the expansion and contraction deformation of the spring sheet in the length direction, the female plug 200 is translated on a plane perpendicular to the hole depth direction of the window hole 121. Since the spring sheet is arranged along the circumference of the female plug 200, the female plug 200 can be moved in any direction on the plane.

[0042] By utilizing the technical solution of the above embodiment, a first elastic member 300 is arranged in the cavity in the box body, and the first elastic member 300 is distributed along the circumference of the female plug 200. The first elastic member 300 can cause the female plug 200 to translate on a plane perpendicular to the depth direction of the window hole 121 through telescopic deformation. In this way, when the male plug 400 is inserted into the female plug 200, even if the female plug 200 is not aligned with the male plug 400, the female plug 200 can automatically align the female plug 200 with the male plug 400 by generating a small range of deviation, so that the pins of the male plug 400 and the pins of the female plug 200 are parallel to each other, thereby achieving smooth and effortless insertion of the male plug 400 into the female plug 200.

[0043] Reference Figure 2 , Figure 3 As shown, in some embodiments of the present application, the connector further includes a second elastic member 500, which is disposed in the cavity and located on the side of the female plug 200 away from the window hole 121, and can move the female plug 200 along a first direction by telescopic deformation, and the first direction is the hole depth direction of the window hole 121. In some specific embodiments, the second spring member is a spring or a spring sheet, and preferably, the second spring member is a spring. The axis of the spring is parallel to the hole depth direction of the window hole 121, the lower end of the spring is against the base 110, and the upper end of the spring is against the female plug 200. When the male plug 400 is inserted into the female plug 200, under the compression elastic force of the spring, the female plug 200 can have a tendency to move toward the male plug 400, so that the male plug 400 and the female plug 200 are pressed against each other to achieve an anti-drop effect. It should be noted that the pins of the male plug 400 and the female plug 200 are respectively connected to multiple wiring harnesses. That is to say, after the male plug 400 is inserted into the female plug 200, the male plug 400 itself will be subjected to downward pressure under the pressure of the wiring harness. On this basis, the second elastic member 500 drives the female plug 200 to maintain upward pressure, so that the male plug 400 and the female plug 200 are pressed against each other. During the movement of the vehicle, since the male plug 400 and the female plug 200 are always kept in a state of pressing against each other, the connection between the male plug 400 and the female plug 200 can be prevented from loosening due to bumps, and the occurrence of false connection can be effectively avoided.

[0044] Reference Figure 3 , Figure 4 , Figure 5 As shown, in some embodiments of the present application, the connector further includes a fixed frame 600, the outer wall of the fixed frame 600 is in clearance with the inner wall of the cavity, one end of the first elastic member 300 abuts against the outer surface of the female plug 200, and the other end abuts against the inner wall of the fixed frame 600; one end of the second elastic member 500 abuts against the inner wall of the cavity, and the other end abuts against the fixed frame 600. In some specific embodiments, the fixed frame 600 is a square frame, the first elastic member 300 is a spring sheet, a pair of spring sheets are respectively arranged at the four corners of the square frame, and spring sheets are symmetrically arranged on the two long sides of the square frame, and all the spring sheets together limit the connector in the middle position of the square frame; the second elastic member 500 is a spring, the axis of the spring is parallel to the hole depth direction of the window hole 121, the lower end of the spring abuts against the base 110, and the upper end of the spring abuts against the end of the direction frame. By setting the fixing frame 600 , the first elastic member 300 drives the female plug 200 to move along the depth direction of the window hole 121 by pushing the fixing frame 600 . Meanwhile, the connector can also translate on a plane perpendicular to the depth direction of the window hole 121 .

[0045] Reference Figure 5 , Figure 6 , Figure 7 As shown, in some embodiments of the present application, the fixing frame 600 includes a base 610 and a cover plate 620, the base 610 is formed with a mounting groove 611, the first elastic member 300 is arranged in the mounting groove 611, one end of the first elastic member 300 abuts against the outer surface of the female plug 200, and the other end abuts against the inner side wall of the mounting groove 611, the bottom wall of the mounting groove 611 is provided with a first through hole 612, and the upper end of the female plug 200 extends out from the first through hole 612; the cover plate 620 is arranged at the notch of the mounting groove 611, and the cover plate 620 is provided with a second through hole 621, and the lower end of the female plug 200 extends out from the second through hole 621. In some specific embodiments, a boss is provided on the outer surface of the female plug 200 along the circumferential direction, the first elastic member 300 is a spring sheet, the inner end of the spring sheet abuts against the boss, the depth of the mounting groove 611 is equal to the width of the spring sheet, so that the opposite sides of the spring sheet and the opposite sides of the boss abut against the bottom wall of the mounting groove 611 and the cover plate 620 respectively, and the spring sheet and the female plug 200 are installed in the mounting groove 611. In this way, relative displacement between the first elastic member 300 and the female socket is prevented during the up and down movement of the female socket.

[0046] Reference Figure 2 , Figure 3As shown, in some embodiments of the present application, the connector further includes a guide post 710 and a guide sleeve 720. The guide post 710 is mounted on the base 110, and the central axis of the guide post 710 is parallel to the first direction; the guide sleeve 720 is disposed on the base 610, and the inner wall of the guide sleeve 720 is slidably matched with the outer wall of the guide post 710. The guide sleeve 720 is slidably matched with the guide post 710, so that the second elastic member 500 is limited to be able to expand and contract only along the depth direction of the window hole 121, that is, the push force of the female socket on the male socket is limited to always be along the depth direction of the window hole 121, which can prevent the female socket and the male socket from being subjected to stress during operation.

[0047] Reference Figure 2 , Figure 6 As shown, in some embodiments of the present application, the guide sleeve 720 is arranged on the inner bottom wall of the installation groove 611, and a gap is formed between the inner wall of the guide sleeve 720 and the outer wall of the guide column 710.

One end of the spring abuts against the inner wall of the cavity, and the other end of the spring abuts against the inner bottom wall of the installation groove 611, which is conducive to stably installing the spring on the base 110. The position corresponding to the guide sleeve 720 is provided with an avoidance hole 622 on the cover plate 620. Specifically, the avoidance hole 622 is a U-shaped hole opened at the end of the cover plate 620, and the guide sleeve 720 passes through the U-shaped hole for easy installation.

[0048] Reference Figure 5 , Figure 6 , Figure 7 As shown, in some embodiments of the present application, a limiting portion is provided at the connection between the cover plate 620 and the base 610.

An inclined surface and a stop surface are formed on the block 613, and the inclined surface is located on the inner side of the block 613, and the stop surface is arranged opposite to the notch. Among them, along the direction from the notch to the bottom of the groove, the distance between the inclined surface and the inner side wall of the block 613 gradually increases. The installation process of the cover plate 620: the edge of the cover plate 620 is squeezed along the inclined surface until the cover plate 620 enters behind the stop surface, and the two sides of the cover plate 620 are respectively stopped by the stop surface and the notch, so as to realize the fixing of the cover plate 620 on the base 610, which can be quickly installed, and the cover plate 620 is not easy to open.

[0049] The connector of the above embodiment has at least the following beneficial effects:

[0050] 1. The first elastic member 300 can cause the female plug 200 to translate on a plane perpendicular to the depth direction of the window hole 121 through telescopic deformation. In this way, when the male plug 400 is inserted into the female plug 200, even if the pins of the female plug 200 and the male plug 400 are not parallel, the female plug 200 can produce a small range of offset to make the pins of the male plug 400 parallel to the pins of the female plug 200, so that the female plug 200 is automatically aligned with the male plug 400, so that the male plug 400 can be smoothly inserted into the female plug 200 without effort.

[0051] 2. The second elastic member 500 can keep the upward pressure on the female plug 200, so that the male plug 400 and the female plug 200 are pressed against each other. During the movement of the vehicle, since the male plug 400 and the female plug 200 are always kept in a pressed state, the connection between the male plug 400 and the female plug 200 can be prevented from loosening due to bumps, and the occurrence of false connection can be effectively avoided.

[0052] 3. The first elastic member 300 and the second elastic member 500 can play a role in shock absorption, so that the male plug 400 and the female plug 200 are subjected to less bumps and vibrations, thereby reducing the probability of loosening.
