Description

Technical Field

[0001] This utility model belongs to the field of electrical connectors, and specifically relates to a split-type electrical connector and electrical equipment. Background Technology

[0002] Due to the complex installation of internal equipment in new energy vehicles, separate sockets have emerged in existing technologies to facilitate connector installation. For example, utility model patent CN217720175U discloses a separate socket for a connector, which includes a housing and terminals (i.e., wiring components). The housing can be used to connect to equipment, and the terminals have built-in contacts that can connect wires. The terminals can be assembled onto the housing to form an integral connector; specifically, the terminals and housing can be fixedly assembled using a snap-fit ​​structure.

[0003] In the above technical solution, because the snap-fit ​​is rigidly connected to the terminal, the housing and terminal are assembled. If the housing is damaged, the entire connector set needs to be replaced, which is costly and difficult to operate.

[0004] The utility model patent with authorization announcement number CN221487013U provides a split connector, which includes a panel connector assembly (i.e., housing) and a circuit board connection assembly (i.e., terminal). The panel connector assembly and the circuit board connector assembly are connected by a detachable snap-fit ​​structure. Specifically, one end of the snap-fit ​​is suspended, and the suspended end is a pressing part that is easy to press. Pressing the pressing part can drive the snap-fit ​​to disengage from the slot, thereby detaching the connection between the circuit board connection assembly and the panel connector assembly, and thus allowing the panel connector assembly to be replaced separately.

[0005] In the above technical solution, the clips are located at both ends of the circuit board connecting assembly in the thickness direction, which can easily result in the circuit board connecting assembly being too thick. In some cases, the space reserved for electrical equipment (such as battery packs) is insufficient, making it difficult to install excessively thick circuit board connecting assemblies properly. Utility Model Content

[0006] The purpose of this invention is to provide a split-type electrical connector to solve the technical problem of excessive thickness in existing split-type connectors with detachable housings and terminals. Another purpose of this invention is to provide an electrical device having the aforementioned split-type electrical connector to solve the same technical problem.

[0007] To achieve the above objectives, the technical solution for the split-type electrical connector provided by this utility model is as follows:

[0008] A split-type electrical connector includes a housing and a wiring assembly. The housing is used for mounting on a mounting panel of an electrical device, and the wiring assembly is used for connecting to components inside the electrical device via a cable. One of the housing and the wiring assembly has latches at both ends in the width direction, and the other has a latch engagement structure that corresponds to and engages with the latches to lock them in place. The latches include elastic cantilever sections, which have locking portions that engage with the latch engagement structure and force-bearing portions that withstand external forces to deform the cantilever sections and release the locking portions and the latch engagement structure from their locked state.

[0009] As a further improvement, a snap fastener is provided on the wiring assembly, a snap fastener engagement structure is provided on the housing, and the force-bearing part is provided with a pressing structure for bearing the pressing pressure.

[0010] As a further improvement, the pressing structure is equipped with outward-curving anti-detachment protrusions.

[0011] As a further improvement, the raised surface of the anti-slip protrusion is an arc-shaped surface.

[0012] As a further improvement, the back of the housing has a mating surface for fitting with the mounting panel of the electrical equipment, and the snap-fit ​​structure extends beyond the mating surface to the back side, and the distance beyond the mating surface is sufficient for the snap-fit ​​structure to pass through the mounting panel and extend into the electrical equipment.

[0013] As a further improvement, the snap-fit ​​structure consists of snap-fit ​​plates respectively located at both ends of the housing width direction.

[0014] As a further improvement, the outer periphery of the wiring assembly is provided with a protrusion for engaging with the tail end of the housing to guide the wiring assembly into the housing. Each end of the protrusion in the width direction is provided with a clearance notch for avoiding the snap-fit ​​plate, and the root of the cantilever section is located at the clearance notch.

[0015] As a further improvement, both ends of the wiring assembly in the width direction are provided with clearance grooves to allow for deformation of the cantilever section.

[0016] This utility model relates to an invention based on element modification, and its beneficial effects are as follows: In use, the split-type electrical connector of this utility model allows the housing and terminals to be connected separately to electrical equipment and cables, and then connected as a single unit via a snap-fit ​​structure. If the housing is damaged and needs replacement, after disconnecting the housing from the electrical equipment, force is applied to the stressed portion, causing the cantilever section to elastically deform and unlock the snap-fit, facilitating separate replacement of the housing and reducing costs. Unlike existing technologies, the snap-fit ​​of the split-type electrical connector in this utility model is located at both ends of the housing or terminals in the width direction, without occupying space in the thickness direction of the connector. This allows the connector thickness to be controlled within a suitable range, facilitating installation and use.

[0017] To achieve the above objectives, the technical solution for the electrical equipment provided by this utility model is as follows:

[0018] An electrical device is provided with a mounting panel, on which an electrical connector is mounted. The electrical connector is electrically connected to components inside the electrical device via a cable. The electrical connector includes a housing and a wiring assembly. The housing is mounted on the mounting panel of the electrical device, and the wiring assembly is connected to the components inside the electrical device via a cable. One of the housing and the wiring assembly has latches at both ends in the width direction, and the other has a latch engagement structure that corresponds to and engages with the latches to lock the latches. The latches include an elastic cantilever section, which has a locking part that engages with the latch engagement structure and a force-bearing part for bearing external force to deform the cantilever section and release the locking part and the latch engagement structure from the locked state.

[0019] As a further improvement, a snap fastener is provided on the wiring assembly, a snap fastener engagement structure is provided on the housing, and the force-bearing part is provided with a pressing structure for bearing the pressing pressure.

[0020] As a further improvement, the pressing structure is equipped with outward-curving anti-detachment protrusions.

[0021] As a further improvement, the raised surface of the anti-slip protrusion is an arc-shaped surface.

[0022] As a further improvement, the back of the housing has a mating surface that fits against the mounting panel of the electrical equipment, and the snap-fit ​​structure extends beyond the mating surface to the back side, and the distance beyond the mating surface is sufficient for the snap-fit ​​structure to pass through the mounting panel and extend into the interior of the electrical equipment.

[0023] As a further improvement, the snap-fit ​​structure consists of snap-fit ​​plates respectively located at both ends of the housing width direction.

[0024] As a further improvement, the outer periphery of the wiring assembly is provided with a protrusion for engaging with the tail end of the housing to guide the wiring assembly into the housing. Each end of the protrusion in the width direction is provided with a clearance notch for avoiding the snap-fit ​​plate, and the root of the cantilever section is located at the clearance notch.

[0025] As a further improvement, both ends of the wiring assembly in the width direction are provided with clearance grooves to allow for deformation of the cantilever section.

[0026] As a further improvement, the cable length is such that the electrical connector can be pulled outward relative to the electrical equipment to expose the stressed part.

[0027] This utility model is an improved invention, and its beneficial effects are: if the housing of the electrical connector is damaged and needs to be replaced, after disconnecting the housing from the electrical equipment, force can be applied to the stressed part, causing the cantilever section to elastically deform and thus unlocking the latch, facilitating the replacement of the housing separately and reducing costs. Unlike existing technologies, the latches of the split-type electrical connector in this utility model are located at both ends in the width direction of the housing or terminal, without occupying space in the thickness direction of the connector. This allows the thickness of the connector to be controlled within a suitable range, facilitating installation and use. Attached Figure Description

[0039] To provide a modular electrical connector that allows for individual shell replacement without excessive thickness, the basic technical concept of this invention is to arrange the snap-fit ​​and corresponding snap-fit ​​mating structure that can be unlocked and detached from the snap-fit ​​on both sides of the width direction of the modular electrical connector. This allows for better utilization of the width dimension of the modular electrical connector to arrange the snap-fit, preventing the connector from becoming too thick and facilitating installation. Furthermore, in actual use, if the shell is damaged, the snap-fit ​​and snap-fit ​​mating structure can still be separated to complete the individual replacement of the shell.

[0040] Based on the above concept, the present invention will be further described in detail below with reference to different embodiments.

[0041] Specific embodiments of the split-type electrical connector provided by this utility model:

[0042] The split-type electrical connector provided in this embodiment includes a housing 1 and a wiring assembly 2, as shown in the figure. Figure 1 As shown, it is used to connect electrical equipment. Specifically, the electrical equipment can be a vehicle's battery pack, DC / DC device, PDU branching device, etc., and the electrical equipment is equipped with a mounting panel 3. For example, when the electrical equipment is a battery pack, see [reference needed]. Figure 3 Mounting panel 3 can be the battery pack housing or a separate panel mounted on the housing. The housing 1 of the split-type electrical connector can be mounted on mounting panel 3. Wiring assembly 2, such as... Figure 2 As shown, it includes insulators, contacts, etc. Depending on actual needs, contacts can be divided into power contacts and signal contacts. The specific arrangement of the contacts is not limited here and can be consistent with existing technology. For example... Figure 4 and Figure 5 As shown, generally, the end of the connector used to mate with the adapter connector is the front end or the first end. The front end of the wiring assembly 2 can be inserted into the housing 1 to complete the assembly, and the rear end can be connected to the cable 5, which then makes a conductive connection to the corresponding components (such as circuit boards) inside the electrical equipment. Compared with integrated connectors, this split-structure connector allows the housing 1 and wiring assembly 2 to be installed separately and then assembled into a whole, which is convenient and efficient.

[0043] The housing 1 and the wiring assembly 2 are locked together by a snap-fit ​​structure. It is easy to understand that the snap-fit ​​201 can be located on the wiring assembly 2, and correspondingly, a snap-fit ​​structure 101 should be provided on the housing 1 to lock the snap-fit ​​201. Alternatively, the snap-fit ​​201 can also be located on the housing 1, and correspondingly, a snap-fit ​​structure 101 should be provided on the wiring assembly 2 to lock the snap-fit ​​201.

[0044] Unlike existing technologies, in this embodiment, the latch 201 is disposed at both ends of the width direction at the corresponding position. Taking the example shown in the figure where the latch 201 is disposed on the wiring assembly 2, the latch 201 is disposed at both ends of the width direction (i.e., the arrangement direction of the power contacts) of the wiring assembly 2. Of course, when the latch 201 is disposed on the housing 1, the latch 201 is disposed at both ends of the width direction of the housing 1.

[0045] To facilitate easy replacement of housing 1 later, housing 1 and wiring assembly 2 are also connected by a detachable snap-fit ​​structure 201. Specifically, snap-fit ​​201 includes a flexible cantilever section, which has a locking part 202 that engages with snap-fit ​​structure 101 to lock snap-fit ​​201. Specifically, locking part 202 can be a barbed structure, a semi-circular protrusion, etc., which guides snap-fit ​​201 to move relative to snap-fit ​​structure 101 during installation and locks it in place. Simultaneously, the cantilever section also has a force-bearing part to withstand external force, causing deformation of the cantilever section and thus releasing the locking part 202 and snap-fit ​​structure 101 from their locked state. In other words, if housing 1 is damaged and needs replacement during subsequent use, force can be applied to the force-bearing part to deform snap-fit ​​201, thereby unlocking snap-fit ​​201 and snap-fit ​​structure 101, facilitating the separate removal and replacement of housing 1.

[0046] by Figure 2 , Figures 4-9 The buckle 201 shown is installed in the wiring assembly 2 and the buckle mating structure 101 as an example. The force-bearing part mentioned above is a pressing structure used to withstand pressing pressure. Figure 6 and Figure 7 As shown, the buckle 201 can be pressed inward (specifically, by hand or with a tool) to separate the locking part 202 from the buckle engagement structure 101, thereby releasing the locked state and allowing the housing 1 to be removed separately.

[0047] Specifically, regarding how to achieve the locking and engaging of the snap-fit ​​structure 101 and the snap-fit ​​201, such as... Figure 1 As shown, the snap-fit ​​structure 101 can be provided with a snap-fit ​​hole 102, which can be a blind hole or a through hole. Of course, a boss can also be provided on the snap-fit ​​structure 101, which can "hook" with the locking part 202. The specific locking method can be the same as the prior art, and will not be specifically limited here.

[0048] Based on the above embodiments, in some preferred embodiments, to overcome the friction between the housing 1 and the wiring assembly 2 when separating them, and to facilitate operation, such as... Figure 2 As shown, the aforementioned pressing structure is provided with an outwardly protruding anti-slip protrusion 203. It is easy to understand that during operation, the anti-slip protrusion 203 can engage with the operator's fingers or pressing tool to prevent slippage. However, it should be emphasized that those skilled in the art will understand that in other embodiments, the end of the cantilever section, i.e., the pressing structure, can also be a straight structure, and the operator can wear gloves with a rough surface to increase friction during pressing.

[0049] Furthermore, when the buckle 201 is pressed (squeezed) by hand, in order to increase the contact area between the anti-detachment protrusion 203 and the operator's fingers, such as... Figure 2 As shown, the raised surface of the anti-slip protrusion 203 is curved. This increases the contact area between the anti-slip protrusion and the finger, and also avoids the unpleasant experience caused by the edge partially contacting the finger.

[0050] In other preferred embodiments, such as Figure 1 , Figure 4 and Figure 5 As shown, the back of the housing 1 has a mating surface for fitting with the mounting panel 3. After the housing 1 is installed, the mating surface is tightly fitted to the mounting panel 3, and a sealing ring can be installed between this surface and the mounting panel 3. The aforementioned snap-fit ​​structure 101 extends towards the back and beyond the mating surface, with the extension distance sufficient to allow the snap-fit ​​structure 101 to be inserted into the back of the mounting panel 3 during use. At this time, the snap-fit ​​structure 101 can engage with the through hole on the mounting panel 3 to determine the position of the housing 1, facilitating the installation of the housing 1 and also facilitating the connection of the snap-fit ​​201. Furthermore, the snap-fit ​​structure 101 does not affect the normal setting of related components within the housing 1. However, it should be noted that in other optional embodiments, the snap-fit ​​structure 101 may not extend beyond the mating surface, but rather be located at the opening of the insertion hole for the wiring assembly 2 on the back of the housing 1, essentially flush with the mating surface.

[0051] Furthermore, in some preferred embodiments, such as Figure 1 As shown, the snap-fit ​​structure 101 is composed of snap-fit ​​plates respectively disposed at both ends of the housing 1 in the width direction. Compared with the structure with a complete ring, this structure is simpler and saves materials while ensuring the basic locking function.

[0052] Furthermore, such as Figure 2 , Figure 4 , Figure 5As shown, the outer periphery of the wiring assembly 2 (insulator) is provided with a protruding edge 204 for engaging with the tail end of the housing 1. During assembly of the wiring assembly 2 and the housing 1, the protruding edge 204 engages with the tail end of the housing 1 to guide the wiring assembly 2 into the housing 1. At both ends of the protruding edge 204 in the width direction, corresponding to the positions of the two snap-fit ​​plates, there are clearance notches 205 to avoid the snap-fit ​​plates. Furthermore, the root of the cantilever section of the snap-fit ​​201 is located at the clearance notch 205. Compared to other positions where the snap-fit ​​201 is located outside the clearance notch 205, this allows the snap-fit ​​201 to be recessed overall, reducing the overall width of the wiring assembly 2 and facilitating installation and use.

[0053] In some other preferred embodiments, such as Figure 2 As shown, the two ends of the wiring assembly 2 in the width direction are also provided with relief grooves 206 for the deformation of the cantilever section. Similarly, the cantilever section does not need to be extended too "high" in this case, which can further shorten the overall width of the wiring assembly 2 and facilitate installation and use.

[0054] It should be emphasized here that the attached drawings only show the preferred configuration where the latch 201 is located on the wiring assembly 2 and the latch engagement structure 101 is located on the housing 1. In this configuration, the latch 201 can be released by pressing the latch 201's pressing structure. However, for the case where the latch 201 is located on the housing 1, for example, it can be... Figure 4 and Figure 5 The latching structure 101 in the middle can be regarded as a latch, and at this time, an outward force needs to be applied to the force-bearing part to expand the latch. It is not difficult to understand that it is more convenient and efficient to set the latch 201 on the wiring assembly 2 and unlock it by pressing the latch 201.

[0055] Furthermore, in some preferred embodiments, a shielding structure may be provided inside the housing 1. Compared to embodiments without a shielding structure or where the shielding is located in the wiring assembly 2, it is clear that providing a shielding structure can effectively prevent crosstalk, while the housing 1 can also protect the shielding structure.

[0056] To facilitate the installation and disassembly of housing 1, such as Figure 1 and Figure 3 As shown, the housing 1 and the mounting panel 3 can be connected using connecting bolts 4. Specifically, bolt holes 103 for the connecting bolts 4 to pass through are provided at the four corners of the housing 1. Compared with the prior art that uses two connecting bolts 4, this method obviously has a better locking effect.

[0057] In summary, the split-type electrical connector in this embodiment utilizes the space in the width direction of the connector to set a detachable snap-fit ​​structure. While ensuring that the housing 1 can be replaced individually, the thickness of the connector can be controlled within a small range, making it convenient for installation and use.

[0058] Specific embodiments of the electrical equipment in this utility model:

[0059] The electrical equipment includes a mounting panel on which a separate electrical connector, as described in the embodiments above, is mounted (and will not be further described here). The separate electrical connector is electrically connected to the corresponding components (e.g., circuit boards or controllers) of the electrical equipment via cable 5.

[0060] More preferably, to facilitate replacement of housing 1, the length of cable 5 can be appropriately extended, leaving a certain slack, so that the electrical connector can be pulled outward relative to the mounting panel 3 to expose the aforementioned stress-bearing part. For example... Figures 6-9 As shown, when it is necessary to replace housing 1, the connection between mounting panel 3 and housing 1 can be disconnected first, and then the connector can be pulled out of the electrical equipment until the stressed part is exposed, thus directly completing the disassembly and replacement of housing 1. In this way, it is not necessary to remove the entire mounting panel 3 when replacing housing 1, which is convenient and efficient.

[0061] 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.
