Description
Technical Field
[0001] This utility model relates to the field of electrical connector technology, and in particular to a quick-connect connector socket and battery pack. Background Technology
[0002] Pure electric commercial vehicles have large battery capacities and various battery configurations. To meet the battery capacity requirements of different models, commercial vehicles design battery packs as standard packs with different cell capacities. Standard battery packs do not contain contactors, and the battery input and output circuits are always energized. The input and output interfaces of the battery pack mostly use quick-connect connectors. The quick-connect connector socket is installed on the side wall of the battery pack housing, and the quick-connect connector plug connects the cable. The quick-connect connector plug and quick-connect connector socket are mated and plugged into each other to connect the circuit.
[0003] To ensure a reliable connection between the plug and socket, connectors typically feature a locking structure, commonly either bolt-locking or handle-locking. Bolt-locking connectors secure the plug and socket with a bolt. The basic structure of a handle-locking connector can be found in a quick-connect connector disclosed in Chinese Utility Model Patent CN217158818U. This connector has a first part and a second part that interlock, with the first part forming the plug and the second part forming the socket. The first outer shell of the first part forms the plug housing, and the second outer shell of the second part forms the socket housing. The second outer shell has a fixing part for connecting external devices and a first snap-fit protrusion. The fixing part is a fixing plate, which is fixed to the device housing by a bolt. A plug-in body protrudes from the center of the fixing plate. The first snap-fit... The protrusion forms an ear post and is located on the outer wall of the plug body. The outer side of the first housing has a second locking protrusion. The assist wrench has a fixing hole and a sliding track, which is a slide. The fixing hole cooperates with the second locking protrusion to make the assist wrench hinged to the first housing. The assist wrench forms a locking handle. The sliding track cooperates with the first locking protrusion. After the plug and socket are inserted, the first locking protrusion enters from the entrance of the sliding track of the assist wrench. Pressing and rotating the assist wrench causes the sliding track to rotate relative to the first locking protrusion with the hinge point between the assist wrench and the first housing as the center. The first locking protrusion reaches the end position along the sliding track. Since the sliding track is offset relative to the hinge point, the entrance position is far from the hinge point and the end position is close to the hinge point. Therefore, after the first locking protrusion is at the end position of the sliding track, the plug and socket can be locked.
[0004] The aforementioned handle-locking connector requires a large distance between the lugs on the socket housing and the fixed plate because the locking handle on the plug needs to be rotated and the sliding track is offset relative to the hinge point. This provides room for the locking handle to rotate and lock. To accommodate this large distance, the protrusion of the socket housing's plug body relative to the fixed plate is relatively high, resulting in a larger size in the socket's insertion direction and a correspondingly larger size in the plug's insertion direction. This takes up space and is not conducive to cost savings. Utility Model Content

[0035] The features and performance of this utility model will be further described in detail below with reference to the embodiments.
[0036] The principle and concept of the quick-connect connector socket for the battery pack of this utility model is that a handle clearance groove is set on the fixed plate of the socket housing corresponding to the position of the ear post. The thickness of the fixed plate provides space for the locking handle of the plug to rotate. The distance between the ear post and the fixed plate can be shortened, thereby reducing the overall size of the quick-connect connector socket and saving manufacturing costs.
[0037] Based on the above principles and concepts, this utility model provides several embodiments of a quick-connect connector socket.
[0038] In a basic embodiment, such as Figure 1-5 In the provided embodiment, the quick-connect connector socket serves as the input or output interface of the battery pack. In this embodiment, the battery pack is the device on which the socket is installed, and the battery pack housing 12 is the device housing. The quick-connect connector socket is installed on the side wall of the battery pack housing 12. The quick-connect connector socket is adapted to a quick-connect connector plug. The plug can be a handle-locking plug 9. A locking handle 91 is hinged to the housing of the handle-locking plug 9. The locking handle 91 is provided with a slide that is offset relative to the hinge point. The quick-connect connector socket includes a socket housing 1. The socket housing 1 includes a fixing plate 101 for fixing the quick-connect connector socket to the corresponding device and a plug body protruding from the central area of the fixing plate 101 for plugging. The fixing plate 101 is provided with a fixing structure for fixing the socket as a whole to the device. A locking engagement structure is provided on the outer wall of the plug body. The locking engagement structure has an ear post 4 for engaging and fixing with the slide of the locking handle 91 on the handle locking plug 9. The ear post 4 is spaced apart from the fixing plate 101. After the handle locking plug is plugged into the socket, the ear post is pushed and rotated to enter the slide until the ear post is at the end position of the slide, locking the locking handle on the plug housing and keeping the plug and socket locked.
[0039] To reduce the connector size, the fixing plate 101 is provided with a handle clearance groove 104 at the position corresponding to the ear post 4 in the direction of insertion of the socket and plug. This provides clearance space for the part of the locking handle 91 with the slide when the locking handle 91 of the handle-locking plug 9 rotates along the ear post 4, preventing interference between the locking handle 91 and the fixing plate 101. Moreover, since the handle clearance groove 104 is provided on the fixing plate 101, the rotation space of the locking handle is provided by the thickness of the fixing plate 101, which can reduce the distance between the ear post 4 and the fixing plate 101 to a certain extent. This can reduce the protrusion height of the plug body of the socket housing 1 relative to the fixing plate 101, reduce the volume of the socket housing 1, save assembly space, and reduce the manufacturing cost of the socket.
[0040] Based on the above embodiments, in one embodiment, such as Figure 1-5 In the provided embodiment, the plug body is a plug sleeve 102, the fixing plate 101 has a portion located around the periphery of the plug sleeve, the socket housing 1 includes a plug protrusion 103 disposed inside the plug sleeve, a plug terminal is disposed in the plug protrusion 103, the plug terminal has an interlock terminal 6 and a power socket terminal 7; a shielding cover 8 is fitted on the plug protrusion 103. The locking mechanism includes a side protrusion 105 on the outer wall of the socket 102, and an ear post 4 on the side of the side protrusion 105 furthest from the socket 102. When the socket and plug are connected, the side protrusion 105 is inserted into the corresponding side protrusion insertion groove 94 on the plug housing. Since the ear post 4 is mainly used to cooperate with the slide on the locking handle 91 to fix the handle-locking plug 9 and the socket, if the extension length of the ear post 4 is long and there is no bottom support, it is easy to break. By setting the side protrusion 105 on the locking mechanism and setting the ear post 4 on the side protrusion 105, the extension length of the ear post 4 is reduced and the structural strength of the ear post 4 is improved.
[0041] Based on the above embodiments, in one embodiment, such as Figure 1-5 In the provided embodiment, the side protrusion 105 is connected to the fixing plate 101. In this embodiment, the socket housing is a one-piece molded structure, and the side protrusion 105 is integrally connected to the fixing plate 101 to improve the structural strength of the side protrusion 105. In other embodiments, the side protrusion may not be connected to the fixing plate.
[0042] Based on the above embodiments, in one embodiment, such as Figure 1-5 In the provided embodiment, the outer side of the side protrusion 105 away from the insert sleeve 102 is flush with the groove wall of the handle clearance groove 104, which maximizes the clearance effect while making full use of the fixing plate to support the side protrusion 105.
[0043] Based on the above embodiments, in one embodiment, such as Figure 1-5In the provided embodiment, the side protrusion 103 is a hollow structure, and the side protrusion 103 and the outer wall of the insert sleeve form a square frame structure. The ear post 4 is set on the frame wall of the square frame structure furthest from the insert sleeve. By making the side protrusion 103 a hollow structure, the material used to make the side protrusion 103 can be reduced while ensuring support for the ear post 4, thus saving costs.
[0044] Based on the above embodiments, in one embodiment, such as Figure 1-5 In the provided embodiment, a side protrusion insertion groove 94 is provided on the housing of the quick-connect connector plug to avoid the side protrusion 103 and to be adapted to the side protrusion 103. When the plug and socket are connected, the side protrusion 103 is inserted into the side protrusion insertion groove 94, and the plug housing 1 provides support for the locking engagement part. At the same time, the side protrusion 103 and the side protrusion insertion groove 94 with corresponding shapes can guide the insertion.
[0045] Based on the above embodiments, in one embodiment, such as Figure 1-5 In the provided embodiment, a plurality of reinforcing ribs 106 are also provided on the outer wall of the insert sleeve 102. The reinforcing ribs 106 extend along the insertion direction of the socket. There are two reinforcing ribs 106 on the same side wall of the insert sleeve 102. The side protrusion 105 is located between the corresponding two reinforcing ribs 106, which can enhance the structural strength of the thin-walled insert sleeve 102.
[0046] Based on the above embodiments, in one embodiment, such as Figure 1-5 In the provided embodiment, the reinforcing rib 106 is arranged along the insertion direction of the quick-connect connector plug and socket, and the reinforcing rib 106 is connected to the fixing plate 101 to further improve the strength of the reinforcing rib 106. At the same time, a reinforcing rib 106 insertion groove 93 corresponding to the shape of the reinforcing rib 106 is provided on the housing of the quick-connect connector plug. When inserted, the reinforcing rib 106 is adapted to be inserted into the reinforcing rib 106 insertion groove 93. The plug housing provides support for the locking mating part and can also guide and limit the plug and socket of the quick-connect connector when inserted.
[0047] Based on the above embodiments, in one embodiment, such as Figure 3 , Figure 6In the provided embodiment, the fixed plate 101 is further provided with bolt connection parts for fixed connection with the bolt locking plug 10 by bolts. There are four bolt connection parts located at the four corners of the rectangle. The handle avoidance groove 104 on the fixed plate 101, which avoids the part of the locking handle 91 with a slide, is provided between two bolt connection parts on the same side. In the embodiment provided by this utility model, the handle avoidance groove 104 is through along the connector insertion direction. The handle avoidance groove 104 has an inclined groove wall. The side protrusion 105 is flush with the bottom of the groove. The two bolt connection parts on the same side are spaced apart. The gap between the two is used to form the handle avoidance groove 104. The projection of the ear post 4 on the plane is located at the middle position of the handle avoidance groove 104, so as to avoid the locking handle 91 to the greatest extent.
[0048] Based on the above embodiments, in one embodiment, such as Figure 3 , Figure 6 In the provided embodiment, the bolt connection includes a fixing boss 2 and an embedded nut 3 installed inside the fixing boss 2. The bolt-locking plug 10 is fixed to the socket by the bolt engaging with the embedded nut 3. The thickness of the fixing boss 2 in the insertion direction between the socket and the plug is greater than that of the fixing plate 101 to accommodate the axial dimension of the embedded nut 3, while avoiding excessive thickness of the fixing plate 101. The two thicker fixing bosses 2 can also form a handle clearance groove with greater clearance space.
[0049] Based on the above embodiments, in one embodiment, such as Figure 1-4 In the provided embodiment, the fixing structure on the fixing plate 101 for fixing the quick-connect connector socket to the corresponding device is the fixing hole 5. The socket is fixed to the corresponding device by using bolts in conjunction with the fixing holes. There are a total of 4 fixing holes 5, which are respectively located at the four corners of the fixing plate 101, and the positions of the upper and lower sets of fixing holes 5 correspond to each other to improve the stability of the fixing plate 101.
[0050] Based on the above embodiments, in one embodiment, such as Figure 1-4 In the provided embodiment, the insertion protrusion 103 is a rectangular boss, and its length direction is along the length direction of the fixing plate 101. The insertion sleeve 102 is a rectangular frame corresponding to the shape of the insertion protrusion 103. An annular cavity for inserting the corresponding part of the plug is formed between the insertion sleeve 102 and the insertion protrusion 103. The height of one short side of the insertion sleeve 102 is lower, forming a clearance opening to avoid the plug housing of the quick-connect connector with right-angle cable exit.
