Description

Technical Field

[0001] This utility model belongs to the field of electrical connectors, and in particular relates to a panel and panel assembly for an integrated socket connector housing. Background Technology

[0002] Due to the complex installation of internal equipment in new energy vehicles, separate sockets have begun to appear in existing technologies to facilitate the installation of connectors. For example, the utility model patent with authorization announcement number CN217720175U discloses a separate socket for a connector. This connector includes a housing and terminals (wiring components). The terminals are installed inside the housing to form a complete connector. When in use, the housing can be connected to the mounting panel of the device, and the specific connection method is generally a screw connection.

[0003] The aforementioned connectors still require tightening screws during housing assembly, which places certain demands on assembly space and makes assembly inconvenient. To address this, utility model patent CN218005352U discloses an integrated panel and battery pack. This integrated panel has a connector housing integrally formed with the panel body, meaning the panel body and connector housing are integrally molded (die-cast), resulting in higher integration and eliminating the need for a separate housing, thus facilitating assembly.

[0004] To ensure reliable and stable mating of connectors during normal use, an interlocking structure should be provided between the plug connector and the socket connector, a commonly used type being a rotary handle. For example, patent application CN115986494A discloses an electrical connector assembly including a plug connector and a socket connector. The plug connector has a rotatable (swinging) handle with an arc-shaped hole. The socket connector's housing has lugs at both ends laterally (along the handle's rotation axis). When the plug and socket connectors are mated, the lugs can enter the arc-shaped hole, and when the handle is rotated, the lugs can slide along the arc-shaped hole. After the handle is rotated to its final position, a locking piece can be used to fix the handle, achieving interlocking between the plug and socket connectors.

[0005] The aforementioned rotary handle structure is applicable to locking connectors where the board body and connector housing are integrated. Based on the attached drawings of the utility model patent with authorization announcement number CN218005352U, the connector housing also features an ear post. In actual operation, due to improper handling, such as forceful rotation or misalignment of the force point, the handle can easily deform, causing it to shift towards one side of the rotation axis. This results in the ear post dislodging from the arc-shaped hole, making proper locking difficult. For conventional connector housings, to address this issue, a protruding structure is typically added to one end of the ear post. After the ear post enters the arc-shaped hole, the protruding structure engages with the end face of the handle facing away from the connector housing, preventing the handle from shifting towards the rotation axis. However, for integrated panels where the board body and housing are large, and the small protruding structure on the ear post is small and thin, poor demolding quality and difficulty in mold ejection can occur. Therefore, it is difficult to add a protruding structure on the ear post to engage with the arc-shaped hole. This poses a high risk of the handle and earpiece separating during normal locking of the connector, making it difficult to lock properly. Utility Model Content

[0006] The purpose of this invention is to provide a panel for an integrated socket connector housing, thereby solving the technical problem in the prior art where the handle and lugs of an integrated connector housing panel are at high risk of separation when the handle is locked, making it difficult to lock properly. Another purpose of this invention is to provide a panel assembly to solve the same technical problem.

[0007] To achieve the above objectives, the technical solution for the panel of the integrated socket connector housing provided by this utility model is as follows:

[0008] A panel for an integrated socket connector housing includes a plate and a socket connector housing integrally formed with the plate. The socket connector housing has two lugs for engaging with arc-shaped holes at both ends of the rotation axis direction of the rotating handle on the plug connector to lock the plug connector and the socket connector housing. The plate has two limiting protrusions located on the side of the two lugs away from the socket connector housing. There is a limiting interval between the two limiting protrusions and the socket connector housing for the rotating handle to enter and for limiting the rotation of the rotating handle in the rotation axis direction.

[0009] As a further improvement, the limiting protrusion is flat at least on the side closest to the socket connector housing.

[0010] As a further improvement, the limiting protrusion is a triangular plate-shaped structure, and the extension direction of the plate surface of the limiting protrusion is parallel to the radial direction of the trunnion.

[0011] As a further improvement, the panel is made of metal.

[0012] This utility model is an improved invention, and its beneficial effects are as follows: Two limiting protrusions are added to the plate body. When the plug connector is inserted and locked, the two lugs on the socket connector housing can still enter the arc-shaped holes on the plug connector, ensuring proper locking. During panel manufacturing, the limiting protrusions protrude from the plate surface and are not directly connected to the lugs, facilitating demolding. Unlike existing technologies, the rotating handle can enter the limiting gap between the limiting protrusions and the socket connector housing. Under the limiting action of the limiting protrusions, the rotating handle will not move to one side of the rotation axis, thus preventing the rotating handle from separating from the lugs and ensuring proper locking of the rotating handle. Moreover, after the rotating handle is locked, the limiting action of the limiting protrusions also allows the rotating handle to remain more stably in the locked position, improving locking reliability.

[0013] To achieve the above objectives, the technical solution for the panel assembly provided by this utility model is as follows:

[0014] A panel assembly includes a panel, the panel including a plate body and a socket connector housing integrally formed with the plate body, the socket connector housing containing a wiring assembly, the socket connector housing having two lugs respectively for engaging with arc-shaped holes at both ends of the rotation axis direction of a rotating handle on a plug connector to lock the plug connector and the socket connector housing, the plate body having two limiting protrusions respectively located on the side of the two lugs away from the socket connector housing, the two limiting protrusions having a limiting interval between them and the socket connector housing for the rotating handle to enter and for limiting the rotation of the rotating handle in the rotation axis direction.

[0015] As a further improvement, the limiting protrusion is flat at least on the side closest to the socket connector housing.

[0016] As a further improvement, the limiting protrusion is a triangular plate-shaped structure, and the extension direction of the plate surface of the limiting protrusion is parallel to the radial direction of the trunnion.

[0017] As a further improvement, the panel is made of metal, and the wiring assembly includes an insulator and a shield fixed to the insulator. The shield is provided with contact springs that are electrically connected to the socket connector housing.

[0018] As a further improvement, the outer periphery of the insulator is provided with a snap fastener for fixing the wiring assembly and the socket connector housing. At least one end of the snap fastener in the width direction is provided with a guide boss, and the inner periphery of the socket connector housing is provided with a guide groove that cooperates with the guide boss to guide the wiring assembly into place.

[0019] As a further improvement, a gap is provided between the guide boss and the insulator, and a portion of the shield is inserted into the gap to fix the shield to the insulator.

[0020] As a further improvement, the wiring assembly includes an insulator and a contact, the insulator having a mating end for mating with a plug connector and an insertion cavity opposite to the mating end for the blade terminal of the power supply device to enter, the insertion cavity having an opening for the blade terminal to enter.

[0021] As a further improvement, the inner wall of the insertion cavity is provided with a positioning protrusion for entering the positioning hole on the blade terminal to limit the position of the blade terminal.

[0022] As a further improvement, the opening of the insertion cavity is provided with a ramp guide structure for guiding the blade terminal into the insertion cavity.

[0023] This utility model is an improved invention, and its beneficial effects are as follows: Two limiting protrusions are added to the panel body. When the plug connector is inserted and locked, the two lugs on the socket connector housing can still enter the arc-shaped holes on the plug connector, ensuring proper locking. During panel manufacturing, the limiting protrusions protrude from the panel surface and are not directly connected to the lugs, facilitating demolding. Unlike existing technologies, the rotating handle can enter the limiting gap between the limiting protrusions and the socket connector housing. Under the limiting action of the limiting protrusions, the rotating handle will not move axially, thus preventing the rotating handle from separating from the lugs and ensuring proper locking of the rotating handle. Moreover, after the rotating handle is locked, the limiting protrusions also ensure that the rotating handle remains more stably in the locked position, improving locking reliability.

Detailed Implementation

[0036] To address the issue of unreliable and easily detachable locking of the socket connector housing integrated on the panel with the plug connector, the basic technical concept of this utility model is to add limiting protrusions with a set interval to the socket connector housing on both sides of the connector housing in the transverse direction (parallel to the axis of the lug) of the panel. This allows the rotating handle on the plug connector to enter between the limiting protrusions and the socket connector housing, thereby limiting the position of the rotating handle in the direction of rotation axis and preventing the rotating handle from moving in the direction of rotation axis.

[0037] Based on the above concept, the following provides different embodiments to further describe the present invention in detail.

[0038] Specific embodiments of the panel assembly provided by this utility model:

[0039] The panel assembly provided in this embodiment is as follows: Figure 1 As shown, the device includes a panel that can be installed on a corresponding electrical device, such as a battery pack casing. The panel includes a body 1 and a socket connector housing 4, which are integrally formed with the body 1. The specific forming method can be consistent with existing technology, such as die casting (for metal materials) or injection molding (for plastic materials). The socket connector housing 4 contains a wiring assembly that can connect to the wiring elements of the electrical device, specifically as follows... Figure 7As shown, it includes insulator 5, contacts, etc.

[0040] In automotive environments, the vibration resistance of mating connectors is particularly critical. For example... Figure 2 As shown, after the plug connector 9 pairs are mated, a locking structure is often needed to ensure reliable interlocking of the connectors. A rotary handle structure is a commonly used locking method. Figure 2 and Figure 3 As shown, specifically, the plug connector 9 is provided with a rotating handle 8. The rotating handle 8 can be consistent with the prior art, that is, the opening faces the mating end of the plug connector 9 in a U-shape. The socket connector housing 4 is provided with two lugs 2, which are respectively located on the lateral sides of the socket connector housing 4. Two arc-shaped holes 801 are provided at both ends of the rotation axis direction of the rotating handle 8. The two lugs 2 can respectively enter the two arc-shaped holes 801 and cooperate with the arc-shaped holes 801 to lock the plug connector 9 and the socket connector housing 4. Accordingly, in order to ensure that the lugs 2 can smoothly enter the arc-shaped holes 801 in the initial state, a clearance notch can be provided at the arc-shaped holes 801. The lugs 2 can enter the arc-shaped holes 801 through the clearance notch in the initial state, and as the rotating handle 8 rotates, the lugs 2 can slide in the arc-shaped holes 801.

[0041] In addition, such as Figures 2-6 As shown, the plug connector 9 is also provided with a locking piece 10. After the rotating handle 8 swings to the position, the locking piece 10 can be inserted into the corresponding mating position of the rotating handle 8 to reliably lock the rotating handle 8.

[0042] It is easy to understand that if the operator applies too much force or the force point is not centered when rotating the handle 8, the handle 8 may deform, causing the ear post 2 to come out of the handle 8 and making it difficult to lock. To solve this problem, the plate 1 is also provided with two limiting protrusions 3 located on the side of the two ear posts 2 away from the socket connector housing 4, where "protrusion" refers to protruding from the surface of the plate 1. There is a gap between the limiting protrusions 3 and the socket connector housing 4, such as... Figures 2-6 As shown, this gap allows the rotary handle 8 to enter, specifically a portion of the swing arms at both ends of the rotary handle 8 along its rotation axis. Throughout the entire process of the rotary handle 8 swinging from its initial state to its locked state, a portion of the rotary handle 8 remains within the gap between the limiting protrusion 3 and the socket connector housing 4. In other words, the gap between the limiting protrusion 3 and the socket connector housing 4 is essentially the same as the width of the swing arms of the rotary handle 8. The rotary handle 8 can be reliably limited by the limiting protrusion 3, preventing it from moving outwards along its rotation axis and facilitating the operator's operation to lock the rotary handle 8. Furthermore, even after the rotary handle 8 is locked in place, the limiting protrusion 3 still prevents axial movement of the rotary handle 8, improving the locking reliability of the rotary handle 8 in the locked state.

[0043] In a preferred embodiment, to improve the limiting effect of the limiting protrusion 3 on the rotating handle 8, the side of the limiting protrusion 3 near the socket connector housing 4 can be made flat. In this case, there is surface contact between the rotating handle 8 and the limiting protrusion 3, resulting in a more stable effect. Of course, in other embodiments, it is not excluded that the side of the limiting protrusion 3 near the socket connector housing 4 may be curved.

[0044] To facilitate demolding and avoid the limiting protrusion 3 occupying too much space, in some preferred embodiments, while ensuring the limiting effect, such as Figure 1 As shown, the limiting protrusion 3 is a triangular plate-shaped structure, and the extension direction of the plate surface of the limiting protrusion 3 is parallel to the radial direction of the ear post 2. Compared with other plate-shaped structures such as rectangles, the triangular plate-shaped structure is convenient for demolding, occupies less space, has higher bonding strength with the plate body 1, and is also more aesthetically pleasing.

[0045] Based on any of the above embodiments, in a more preferred embodiment, the panel is preferably made of metal, such as... Figures 7-9 As shown, the wiring assembly includes a shielding cover 6 fixed to the insulator 5. The shielding cover 6 has a contact spring 601 that contacts the socket connector housing 4 to achieve electrical conduction. Compared with other embodiments that use a plastic shell for the panel, the above preferred method has a simpler structure while ensuring shielding effect.

[0046] Furthermore, it can also be referenced. Figures 7-9 A snap-fit ​​fixing structure can be used to fix the wiring assembly to the socket connector housing 4. Specifically, the outer periphery of the insulator 5 is provided with a snap-fit ​​501, and correspondingly, the socket connector housing 4 is provided with a corresponding slot that mates with the snap-fit ​​501. In order to ensure that the snap-fit ​​501 can be smoothly snapped into place, guide protrusions 502 are provided at both ends of the snap-fit ​​501 in the width direction, and the inner periphery of the socket connector housing 4 is provided with a guide groove 401 that mates with the guide protrusions 502 to guide the wiring assembly into place. During the installation of the wiring assembly, the guide protrusions 502 and the guide groove 401 guide and cooperate, which facilitates the installation of the wiring assembly and the snap-fit ​​501 into place.

[0047] The figure illustrates a preferred embodiment where, to ensure the reliable fixation of the wiring assembly and the socket connector housing 4, multiple snap fasteners 501 can be provided circumferentially on the insulator 5. However, the specific number is not limited here. For example, in some embodiments, only two snap fasteners 501 may be provided, and the two snap fasteners 501 may be located at the same end or opposite ends of the insulator 5. As for the guide boss 502, in other embodiments, it is not excluded that the guide boss 502 may only be provided at one end in the width direction of the snap fastener 501.

[0048] It should be noted that in other embodiments, the wiring assembly and the socket connector housing 4 are not completely excluded from being fixed in other ways. The wiring assembly and the socket connector housing 4 are forcibly fixed by interference fit, or the wiring assembly and the socket connector housing 4 are fixed by riveting.

[0049] Furthermore, as a preferred method for fixing the shielding cover 6, such as Figure 8 As shown, a gap is provided between the guide boss 502 and the insulator 5. This gap is approximately equal to the wall thickness of the shield 6. A portion of the shield 6 is inserted into this gap, and under the action of friction, the shield 6 is fixed to the insulator 5. In this case, in addition to its guiding function, the guide boss 502 also has the function of "clamping" and fixing the shield 6, eliminating the need for additional structures to fix the shield 6.

[0050] In addition, to facilitate contact and electrical connection between the contacts and the wiring terminals of the electrical equipment, for example... Figures 8-10 The configuration shown includes blade-type blade terminals 7, and the insulator 5 has a mating end facing away from the plug connector 9 for mating with it. Figure 1 The upper end has an insertion cavity for inserting the blade terminal 7, the insertion cavity having an opening for the blade terminal 7 to enter, and a contact element for contacting and communicating with the blade terminal 7 is located in the insertion cavity. Of course, in other embodiments, the structure of the back of the insulator 5 and the contact element can also be adapted to change according to the different types of wiring terminals of the electrical equipment. For example, the contact element can also be made to protrude from the back of the insulator 5, and the wiring terminal of the electrical equipment can be crimped to the contact element.

[0051] Furthermore, to prevent over-insertion of the blade terminal 7 and to ensure the stability of the blade terminal 7, such as... Figure 10 As shown, the inner wall of the insertion cavity is provided with a positioning protrusion 504 for entering the positioning hole 701 on the blade terminal 7 to limit the position of the blade terminal 7. Correspondingly, the positioning hole 701 is opened on the blade terminal 7. The positioning protrusion 504 can be set on the side of the contact near the opening of the insertion cavity, as long as it does not interfere with the contact. The specific shape of the positioning protrusion 504 is not specifically limited, as long as it fits the positioning hole 701. Compared with the scheme without the positioning protrusion 504 and the positioning hole 701, when inserting the blade terminal 7, the positioning protrusion 504 inserting into the positioning hole 701 indicates that the blade terminal 7 is inserted in place, preventing over-insertion that could damage the blade terminal 7 and the contact. The blade terminal 7 is also more stable during subsequent normal use.

[0052] To facilitate the insertion of the blade terminal 7, preferably, as follows: Figure 9As shown, the opening of the insertion cavity is provided with a ramp guide structure 503 to guide the blade terminal 7 to be inserted smoothly. However, it should be noted that in other embodiments, it is possible that the opening of the insertion cavity is basically flush with the end face of the insulator 5. In this case, a high positional accuracy needs to be ensured when inserting the blade terminal 7.

[0053] Specific embodiments of the panel of the integrated socket connector housing in this utility model:

[0054] The panel of the integrated socket connector housing is the same as the panel structure described in the panel assembly embodiment, and will not be described in detail here.

[0055] Finally, it should be noted that the above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
