Description

Power socket with integrated fuse Technical Field

[0001] The present invention relates to the technical field of conductive connection devices with built-in fuses, and in particular to a power socket with an integrated fuse. Background Art

[0002] In electric vehicles, fuses are often connected in series in the circuits of small current electrical devices such as compressors and PTCs to prevent short-term overload currents from burning the electrical devices. The general practice is to place the fuse in the PDU power socket, and power the electrical device by plugging the power plug of the electrical device into the power socket. For example, the Chinese invention patent application with application publication number CN115733004A discloses an electrical connector socket with an integrated fuse. The plate-shaped base of this socket is used to be fixed on the battery box, and one side has positive and negative terminals for connecting to the positive and negative conductive parts in the battery box, and the other side has positive and negative contacts for plugging with the plug for plugging. It can be clearly seen that when this electrical connector socket is in use, the plug is plugged in perpendicular to the plate-shaped base, that is, the wall of the battery box. This takes up a large space in the direction perpendicular to the wall of the battery box in actual application, which is not conducive to the miniaturization of the power module of new energy vehicles.

[0003] Summary of the Invention

[0004] The object of the present invention is to provide a power socket with an integrated fuse, so as to solve the problem that the existing power socket occupies a large space in a direction perpendicular to the installation panel of the power socket after an adapter plug is inserted.

[0005] The power socket with an integrated fuse of the present invention includes a socket housing, the socket housing having a housing wall, one end of the housing wall having a connection port for fixedly connecting to the socket mounting panel, an installation cavity formed in the housing wall, a fuse and a conductor assembly installed in the installation cavity, an end of the housing wall opposite to the connection port having a mounting opening, a housing cover being detachably connected to the mounting opening, a plug port for receiving an adapter plug being provided on the housing wall, the conductive assembly having a socket plug end extending to the plug port and an internal connection end extending to the connection port, and the fuse being connected in series between the socket plug end and the internal connection end.

[0006] Furthermore, the length direction of the fuse is perpendicular to the direction of the installation opening, and the fuse is detachably connected to the conductor assembly through both ends.

[0007] Furthermore, the length direction of the fuse is parallel to the direction of the plug port.

[0008] Furthermore, there are two plug-in ports for plugging and connecting with two adapter plugs respectively, and the socket plug-in ends of the two plug-in ports are respectively connected to the same internal connection end through fuses.

[0009] Furthermore, the two plug ports are located on opposite sides of the shell wall.

[0010] Furthermore, the two fuses are arranged side by side in parallel.

[0011] Furthermore, a locking component is provided on the housing cover at the side where the plug port is located, and the locking component is used to interlock with the adapter plug to lock the housing cover in the opening direction when the adapter plug is plugged into the plug port.

[0012] Furthermore, the locking component is a lock buckle extending toward the plugging direction. When the adapter plug is plugged into the plugging port, the lock buckle and the adapter plug are plugged into each other in the plugging direction.

[0013] Furthermore, the shell cover and the shell surrounding wall are connected by snap-fit ​​connection.

[0014] The power socket with an integrated fuse of the present invention forms a connection port at one end of the shell wall, and a plug-in port is provided on the shell wall, so that the plug-in port and the connection port are arranged roughly at right angles to form a bent connection structure.

[0020] The features and performance of the present invention are further described in detail below with reference to the embodiments.

[0021] Embodiment 1 of the power socket with integrated fuse of the present invention:

[0022] The overall design concept and technical principle of the power socket with integrated fuse of the present invention are as follows:

[0023] The power socket of the present invention primarily addresses the structural design of existing power sockets, which results in the plug-in direction of the adapter plug being perpendicular to the surface of the mounting panel on which the power socket is mounted when the adapter plug is inserted into the power socket. This causes the plug to occupy a large space perpendicular to the mounting panel. For example, when the mounting panel is a battery case, this plug-in orientation causes the plug to occupy a large space outside the battery case, hindering the miniaturization of power modules for new energy vehicles. The main design concept of the present invention is to improve the structure of the power socket, designing it as a curved socket, so that the adapter plug, after being inserted into the power socket, can extend entirely along the extension direction of the mounting panel, thereby reducing the space occupied by the plug perpendicular to the mounting panel.

[0024] In terms of the structure of the power socket, the power socket of the present invention includes a socket housing having a housing wall. The housing wall is arranged around a centerline to enclose a hollow space, which forms an installation cavity. The housing wall has a connection port at one end extending along the centerline for fixed connection to the socket installation panel, and an installation opening at the other end extending along the centerline. The installation opening communicates with the installation cavity, forming an operating port for installing internal components into the installation cavity. A housing cover is also provided at the operating port. The housing cover is removably connected to the installation opening to seal the installation cavity after the internal components are installed, thereby ensuring the sealing performance of the power socket. The housing wall is also provided with a plug port for connecting with an adapter plug to achieve a plug-and-socket connection. A fuse and a conductor assembly are installed in the installation cavity. The conductive assembly has a socket plug-in end extending to the plug port and an internal connection end extending to the connection port. The socket plug-in end is used to engage with the plug contact of the adapter plug, and the internal connection end is used to connect to the power supply or circuit inside the installation panel. The fuse is connected in series between the socket plug-in end and the internal connection end.

[0025] In the power socket adopting the above solution, since the power socket forms a connection port at one end of the shell wall, and the plug port is provided on the shell wall, the plug port and the connection port are arranged approximately at right angles to form a bent connection structure. In this way, when the adapter plug is plugged into the power socket, it is plugged into the power socket in a direction approximately parallel to the installation panel of the power socket, which greatly saves space in a direction perpendicular to the installation panel of the power socket.

[0026] Based on the above overall concept and technical principles, more specific embodiments are provided below:

[0027] As shown in Figures 1-3, considering the miniaturization and compactness of the structure, the cross-section of the housing wall 1 is generally rectangular. One end of the housing wall 1 has an external flange, which is fixedly connected to the mounting panel via the external flange. The port where the external flange is located is the connection port 10. A slotted cover is disposed at the other end of the housing wall 1. On opposite sides of the slotted cover are latches 32 formed by elastic cantilevers. Hooks are provided on the housing wall at positions corresponding to the latches 32. When the slotted cover is engaged with the connection port 10, the latches 32 engage and lock with the hooks, thereby forming the housing cover 3. Of course, the housing cover 3 can also take various forms. For example, if the mounting opening has a mating flange surface, the housing cover 3 can be directly mated with the mating flange surface and connected to the mounting opening via screws. The fuse is a long strip-shaped structure, connected to corresponding conductor components at both ends and connected in series in the circuit. To facilitate the removal and installation of the fuse, in this embodiment, the length direction of the fuse is perpendicular to the direction of the installation opening, that is, the extension direction of the center line surrounded by the above-mentioned shell wall 1. In this way, after opening the shell cover 3, the two ends of the fuse can be directly removed from the installation opening relatively conveniently.

[0028] Furthermore, as a more preferred embodiment, the length direction of the fuse is parallel to the direction of the plug port 11. Because the extension direction of the conductor assembly at the plug port 11 is consistent with the extension direction of the plug port 11, setting the length direction of the fuse to be parallel to the direction of the plug port 11 can facilitate the electrical connection between the fuse and the conductor assembly. Of course, depending on the different arrangements of the conductor assemblies in the installation cavity, the arrangement of the fuse can of course change accordingly. The above-mentioned embodiments cannot be considered to exclude other embodiments of the present invention. For example, some equally feasible embodiments, when the height of the shell wall 1 is greater than the length of the fuse, can be arranged in the installation cavity in a manner that its length direction extends along the height direction of the shell wall 1, and is located at the side wall position of the shell wall 1 adjacent to the plug port 11.

[0029] The power socket of the present invention can be an ordinary power socket or a PDU socket. Taking the PDU socket as an example, the power socket needs to have a power distribution function. As shown in Figures 1-3, two plug ports 11 are provided on the shell wall 1 of the power socket. The two plug ports 11 are used to plug in two adapter plugs 2 respectively. The conductor assembly inside the power socket includes a positive conductor assembly and a negative conductor assembly corresponding to the positive and negative poles respectively. The positive conductors of the two adapter sockets are connected to the positive conductor assembly in the power socket through fuses, and the negative conductors of the two adapter sockets are directly connected to the negative conductor assembly in the power socket, thereby realizing a one-to-two power distribution. Of course, when more power distribution channels are required, the adapter plug 2 can be a two-way plug 2 including two positive and negative poles, thereby realizing a one-to-four power distribution. Since the internal structure of the power socket does not involve the improvement scheme claimed for protection by the present invention, it will not be described in detail herein.

[0030] When the power socket is provided with two plug ports 11 to realize one-to-two power distribution, the two plug ports 11 are preferably arranged on opposite sides of the shell wall 1, so that the adapter plug 2 can be plugged in and out from opposite sides respectively, and the conductive components and fuses in the installation cavity are easier to arrange. For example, in one embodiment, the two fuses can be arranged side by side in parallel, and the extension direction of the two fuses is parallel to the plugging direction of the adapter plug 2. Of course, in the embodiment shown in Figure 4, the two plug ports are arranged on adjacent sides of the shell wall. Alternatively, in other embodiments, the shape of the installation cavity enclosed by the shell wall can be a regular hexagon, and there can be three plug ports, which are arranged in three directions of the shell wall and evenly distributed circumferentially.

[0031] The present invention also provides a more optimized embodiment of a power outlet with an integrated fuse. In this embodiment, a locking member is provided on the housing cover 3 on the side where the plug port 11 is located. The locking member is configured to interlock with the adapter plug 2, locking the housing cover 3 in the open direction when the adapter plug 2 is plugged into the plug port 11. This arrangement prevents the housing cover 3 from opening when the adapter plug 2 is plugged into the power outlet. This prevents electric shock caused by accidentally opening the housing cover 3 while the socket is plugged in, thereby improving the safety of the power outlet.

[0032] Based on this idea, different implementation methods can be used to achieve the locking between the shell cover 3 and the adapter plug 2. For example, a hook is provided on one of the shell cover 3 and the adapter plug 2, and a hook is provided on the other. When the adapter plug 2 is plugged into the power socket, the hook is hooked with the hook to prevent the shell cover 3 from moving in the opening direction. At this time, the hook or hook provided on the shell cover 3 constitutes the above-mentioned locking component; the embodiment shown in Figures 1-3 is a simpler embodiment, in which a lock buckle 31 extending outward is provided on the groove wall of the groove-shaped buckle cover. When installed on the mounting port, the lock catch 31 is located at the plug-in port 11 and extends toward the adapter plug 2. The adapter plug 2 adopts an existing adapter plug 2, such as the plug disclosed in a fused connector disclosed in Chinese Utility Model Patent No. CN218101836U, which has a set housing. When the adapter plug 2 is plugged into the power socket, the set housing covers the outside of the lock catch 31, and the lock catch 31 extends into the set housing. That is, the two are plugged in the plugging direction, so that the lock catch 31 is blocked by the set housing, and the housing cover 3 cannot move in the opening direction.

[0033] In the embodiment shown in FIG4 , two plug ports are provided on adjacent sides of the housing wall. Since the housing cover 3 is locked by two opposing latches 32 that hook and lock with corresponding latches on the housing wall 1, it is inconvenient to provide a latch 31 where the latches 32 are located. Instead, the housing cover 3 is provided with an outwardly extending latch 31 only on one sidewall adjacent to the sidewall where the latch 32 is located, and the latch 31 interlocks with the corresponding adapter plug 2. Of course, as in the example above, when the housing cover and the connection port are connected via flanges, a latch can be provided on the housing cover at a position corresponding to each plug port, and interlocked with the corresponding adapter plug.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The scope of patent protection of the present invention shall be based on the claims. Any equivalent structural changes made using the description and drawings of the present invention shall be included in the scope of protection of the present invention.
