Description

Technical Field

[0001] This utility model relates to the field of electrical connectors, and in particular to a connector assembly, a connector and its housing and shielding sleeve. Background Technology

[0002] In some scenarios with complex electrical structures, such as in new energy vehicles, a large number of electronic components are used. Therefore, the electromagnetic fields generated by high voltage and high current will cause electromagnetic interference to communication equipment. This requires the whole vehicle and components to have anti-interference and anti-radiation functions. As an important component, the electrical connector plays the role of connecting the system circuit, and its anti-interference and anti-radiation capabilities are particularly important.

[0003] The interference and radiation resistance of connectors are mainly achieved by setting a shielding sleeve inside the cavity of their housing. For example, an inner-lined shielding sleeve is set inside the connector housing cavity, with the tail end of the shielding sleeve extending backward outside the connector cavity. After the connector is installed, the tail end of the shielding sleeve is connected to the connector mounting plate, so that the connector housing, shielding sleeve and mounting plate together form a complete shielding path to shield and protect the terminals inside the connector housing.

[0004] A typical connector structure is as follows Figure 1-2 As shown, the connector includes a connector housing 1, within which connector terminals (not shown) are installed. A terminal mounting module 101 is disposed within the inner cavity of the housing. The terminal mounting module 101 is connected to the inner wall of the connector housing 1 via connecting ribs. Adjacent connecting ribs form a gap for inserting a shielding sleeve. To ensure contact with the mounting panel, the tail end of the shielding sleeve 3 needs to extend beyond the rear end of the connector housing 1. Therefore, a cutout 301 corresponding to the connecting ribs is provided on the shielding sleeve 3. Furthermore, to ensure reliable contact between the shielding sleeve and the mounting panel, a strip-shaped elastic protrusion is provided on the outer wall of the shielding sleeve 3. When the connector is installed in place, the elastic protrusion is compressed by the inner wall of the mounting hole on the mounting panel, thereby reliably abutting against the inner wall of the mounting hole. Since it is installed in the connector housing by insertion, to reduce the resistance when the shielding sleeve is installed into the connector housing, a clearance notch is provided on the wall of the housing corresponding to the elastic protrusion.

[0005] The aforementioned connector achieves high shielding performance through the use of a shielding sleeve, effectively ensuring its anti-interference and anti-radiation performance. However, due to the aforementioned cutouts, a tongue 302 (or cantilever) is formed in the middle of each side of the shielding sleeve. Because the shielding sleeve 3 has a relatively thin wall thickness (typically 0.3mm), the tongue 302 is prone to warping and deformation outwards during installation or transportation. This causes the end of the tongue 302 to frequently press against the edge of the corresponding mounting hole 201 on the mounting panel when installing the connector, obstructing the connector installation. Forcing installation may damage the tongue of the shielding sleeve, leading to a decrease in its shielding performance. Utility Model Content

[0006] The purpose of this invention is to provide a connector that solves the problem that the tongue on the shielding sleeve of existing connectors easily gets stuck with the mounting panel during installation.

[0007] Meanwhile, the purpose of this utility model is also to provide a connector housing and a shielding sleeve for the above-mentioned connector, as well as a connector assembly using the above-mentioned connector.

[0008] To achieve the above objectives, the connector of this utility model adopts the following technical solution: A connector includes a connector housing and a shielding sleeve.

The shielding sleeve has a cut corresponding to the connecting rib, forming a tongue between the cuts. The tip of the tongue faces backward. The tongue has a contact protrusion for contacting and connecting with a mounting panel. A limiting structure is provided on the outer side of the tongue on the connector housing. A limiting mating structure corresponding to the limiting structure is provided on the tongue.

[0017] Furthermore, the shielding sleeve is rectangular, and two or more contact protrusions are arranged side by side on each side wall of the shielding sleeve, with at least some of the contact protrusions on each side wall being staggered in the front-back direction.

[0018] Furthermore, the connector housing has a notch corresponding to the inner side of the tongue to allow space for the tongue to deform inward.

[0019] The beneficial effects of the connector technical solution of this utility model are as follows: The connector of this utility model is an improved invention. By correspondingly setting a limiting structure and a limiting mating structure on the connector housing and the shielding sleeve, when the shielding sleeve is installed into the connector housing, the limiting mating between the limiting structure and the limiting mating structure can prevent the tongue of the shielding sleeve from warping outward, thereby preventing the tip of the tongue from pressing against the mounting panel due to outward warping when the connector is installed on the mounting panel, thus solving the problem of jamming between the shielding sleeve and the mounting panel.

[0020] The connector assembly of this utility model adopts the following technical solution: A connector assembly includes a plug and a socket, which are mutually compatible. The plug or socket includes a connector housing and a shielding sleeve. The connector housing has a terminal mounting module. A shielding sleeve mounting gap is left between the outer periphery of the terminal mounting module and the connector housing, and the module is connected to the connector housing via a connecting rib. The shielding sleeve has cutouts corresponding to the connecting ribs, forming a tongue with its tip facing backward. A contact protrusion for contact with a mounting panel is provided on the tongue. A limiting structure is provided on the outer side of the tongue on the connector housing, and a limiting mating structure corresponding to the limiting structure is provided on the tongue. The limiting structure and the limiting mating structure cooperate to constrain the outward warping of the corresponding tongue, preventing the tip of the tongue from abutting the edge of the mounting hole on the mounting panel corresponding to the connector.

[0021] Furthermore, the fit between the limiting structure and the limiting mating structure is an abutting fit, a contact fit, or a clearance fit.

[0022] Furthermore, the limiting fit structure is composed of limiting protrusions provided on the tongue.

[0023] Furthermore, the tongue is provided with a strip-shaped protrusion extending in the front-back direction, and the limiting protrusion is formed by a portion of the strip-shaped protrusion.

[0024] Furthermore, the contact protrusion is formed by another portion of the strip-shaped protrusion.

[0025] Furthermore, the strip-shaped protrusion is a simply supported beam structure, and the limiting protrusion and the contact protrusion are respectively composed of two parts of the top of the simply supported beam.

[0026] Furthermore, the limiting structure is formed by the wall surface at the corresponding position of the connector housing.

[0027] Furthermore, the connector housing has a notch at the mounting path corresponding to the contact protrusion to avoid the contact protrusion, thereby reducing the installation resistance of the shielding sleeve to the connector housing.

[0031] The beneficial effects of the connector assembly of this utility model: The connector assembly of this utility model is an improved invention. By correspondingly setting a limiting structure and a limiting mating structure on the connector housing and shielding sleeve of the connector, which serves as a plug or socket, when the shielding sleeve is installed into the connector housing, the limiting mating between the limiting structure and the limiting mating structure can prevent the tongue of the shielding sleeve from warping outward. This prevents the tip of the tongue from pressing against the mounting panel when the connector is installed on the mounting panel due to outward warping, thus solving the problem of jamming between the shielding sleeve and the mounting panel.

[0032] The connector housing of this utility model adopts the following technical solution: The connector housing has an inner cavity for mounting connector terminals and a shielding sleeve. The inner cavity contains a terminal mounting module. A shielding sleeve mounting gap is left between the outer periphery of the terminal mounting module and the connector housing, and the module is connected to the connector housing via a connecting rib. A limiting structure is provided on the outer side of the tongue corresponding to the shielding sleeve on the connector housing. The limiting structure is used to cooperate with the limiting mating structure on the tongue of the shielding sleeve to constrain the outward warping of the corresponding tongue, so as to prevent the tip of the tongue from hitting the edge of the mounting hole on the mounting panel corresponding to the connector.

[0037] Furthermore, the connector housing has a notch corresponding to the inner side of the tongue to allow space for the tongue to deform inward.

[0038] The beneficial effects of the connector housing of this utility model: The connector housing of this utility model is an improved invention. Specifically, the connector housing of this utility model is provided with a limiting structure corresponding to the tongue on the shielding sleeve installed during use. Through the cooperation of the limiting structure and the limiting matching structure on the tongue, the tongue can be restricted from warping outward after the shielding sleeve is installed, thereby preventing the tip of the tongue from pressing against the mounting panel due to outward warping when the connector is installed on the mounting panel, thus solving the problem of jamming between the shielding sleeve and the mounting panel.

[0039] The shielding sleeve of this utility model adopts the following technical solution: The shielding sleeve has a cut on its sleeve wall to avoid the connecting ribs in the corresponding connector housing. A tongue is formed between adjacent cuts. The tip of the tongue faces backward. A contact protrusion for contacting and connecting with the mounting panel is provided on the tongue. A limiting fit structure corresponding to the limiting structure provided on the connector housing is provided on the tongue. The limiting structure and the limiting fit structure cooperate to constrain the outward warping of the corresponding tongue to prevent the tip of the tongue from hitting the edge of the mounting hole on the mounting panel corresponding to the connector.

[0040] Furthermore, the fit between the limiting structure and the limiting mating structure is an abutting fit, a contact fit, or a clearance fit.

[0041] Furthermore, the limiting fit structure is composed of limiting protrusions provided on the tongue.

[0042] Furthermore, the tongue is provided with a strip-shaped protrusion extending in the front-back direction, and the limiting protrusion is formed by a portion of the strip-shaped protrusion.

[0043] Furthermore, the contact protrusion is formed by another portion of the strip-shaped protrusion.

[0046] The beneficial effects of the shielding sleeve of this utility model: The shielding sleeve of this utility model is an improved invention. By setting the limiting fit structure on the tongue of the shielding sleeve, when the shielding sleeve is installed on the corresponding connector housing, the limiting fit structure can cooperate with the limiting structure set on the connector housing to constrain the tongue from warping outward, thereby preventing the tip of the tongue from hitting the mounting panel due to outward warping when the connector is installed on the mounting panel, thus solving the problem of jamming between the shielding sleeve and the mounting panel.

[0049] The inner shielding sleeve of a connector is typically made of copper or copper alloy, with a wall thickness of approximately 0.3mm. Therefore, its strength is relatively low, and its resistance to deformation is extremely weak. In actual production, the shielding sleeve is installed onto the connector housing at the factory and sold and used along with the connector. During transport with the connector and during installation onto the corresponding mounting panel, the tongue on the shielding sleeve is prone to warping. When the tongue warps inward (towards the center of the connector), the problem is not obvious. However, if the tongue warps outward, it can easily press against the edge of the mounting hole during the installation of the connector onto the mounting panel, leading to installation difficulties or damage to the tongue due to forced installation. Because it is located at the end of the connector, damage to the tongue is sometimes difficult to detect, which will affect the shielding performance of the shielding sleeve to some extent, thereby reducing the connector's anti-interference and anti-radiation capabilities.

[0050] To avoid the aforementioned problems, the most readily conceived method in the art is to increase the stiffness of the tongue, for example, by increasing the wall thickness of the shielding sleeve or changing the material of the shielding sleeve. However, increasing the wall thickness of the shielding sleeve will inevitably lead to an increase in the size and weight of the connector, which is inconsistent with the current trend of connector miniaturization and will increase the cost of the shielding sleeve and connector. If the stiffness is improved by changing the material of the shielding sleeve, the overall shielding performance of the shielding sleeve may decrease due to the change in material, and the development and application of new materials may also lead to an increase in the cost of the shielding sleeve and connector. In fact, given the limited overall size of the connector, even increasing the wall thickness of the shielding sleeve or improving its material will result in a very limited increase in the stiffness of the tongue.

[0051] Against the backdrop described above, this invention employs a completely different inventive concept from existing technologies. By utilizing the easily deformable nature of the tongue on the shielding sleeve and using the connector housing as a supporting base, it restricts the outward warping and deformation of the tongue, thereby solving the problem of the tongue on the connector's shielding sleeve easily getting stuck with the mounting panel. Based on the above inventive concept, this invention proposes technical solutions for a connector, a connector assembly, a connector housing, and a connector shielding sleeve.

[0052] Based on the above inventive concept, the specific implementation of the connector of this utility model is as follows: like Figure 7-13 As shown, the connector of this utility model includes a connector housing 1. The front end of the connector housing 1 corresponds to the plug end of the connector, and the rear end corresponds to the mounting end of the connector. The plug end is the end that mates with the adapter connector during use, and the mounting end is the end that cooperates with the mounting panel 2 to install the connector onto the mounting panel 2 during use. An inner cavity 102 is provided in the connector housing 1, and a terminal mounting module 101 is provided in the inner cavity. The terminal mounting module 101 is used to mount connector terminals (not shown in the figure). Connector terminals are components used to mate with the adapter connector to conduct current or signals.

[0053] like Figure 7As shown, the outer periphery of the terminal mounting module 101 is connected to the cavity wall of the connector housing 1 via connecting ribs 103. A gap is left between the cavity wall of the housing and the outer periphery of the terminal mounting module 101. This gap allows the shielding sleeve 3 to be installed from front to back between the terminal mounting module 101 and the inner wall of the connector housing, thereby achieving shielding protection for the connector terminals. Connector terminals are mounted on the terminal mounting module 101. For example, terminal mounting holes can be provided on the terminal mounting module 101, and the connector terminals can be installed in the corresponding terminal mounting holes with an interference fit. Alternatively, after the connector terminals are inserted into the terminal mounting holes, they can be pressed and fixed by a pressure plate on one side of the terminal mounting module 101. Of course, in this case, the connector terminals themselves must have a structure that can stop and cooperate with the terminal mounting module 101 to prevent them from directly coming out of the corresponding terminal mounting holes and failing to be pressed. Alternatively, the connector terminals can be directly cast and fixed to the terminal mounting module 101 during the casting process. In fact, there are various types of terminal and terminal mounting module mounting structures in the prior art, and all of these mounting structures are applicable to the connector of this utility model.

[0054] To prevent the connector terminal 102 from being subjected to external electromagnetic interference and radiation, a shielding sleeve 3 is also provided inside the connector housing 1. The shielding sleeve 3 surrounds the connector terminal 102 at its periphery and has a cross-section that approximately matches the cross-section of the inner cavity of the connector housing 1, for example, in... Figure 7 In the illustrated embodiment, the connector is a rectangular connector, and the cross-section of its inner cavity is rectangular, as is the cross-section of the shielding sleeve 3. Of course, in other embodiments, if the connector is a circular connector and the cross-section of the inner cavity of the connector housing 1 is circular, the cross-section of the shielding sleeve 3 can also be set to circular accordingly. To avoid the connecting rib 103, cutouts 301 are provided on both sides of the shielding sleeve 3. The presence of the cutouts 301 on both sides creates a cantilever structure in the middle of the corresponding side. This cantilever structure actually forms a tongue 302, where the cantilever end of the tongue 302 forms its tip, and the other end forms its root.

[0055] To ensure reliable contact with the mounting holes 201 on the mounting panel 2, contact protrusions 303 are provided on the side wall of the shielding sleeve 3. These contact protrusions 303 are elastic protrusions formed by localized deformation of the tongue, for example, as shown in the image. Figure 1-6 It can be designed as a strip (bent shape) as shown, or it can be designed as a convex hull. When the connector is installed on the mounting panel 2, the contact protrusion 303 will contact the inner wall of the mounting hole 201, thereby forming a passage between the shielding sleeve 3 and the mounting panel 2.

[0056] To prevent the tongue 302 from warping outwards (away from the connector terminal) and affecting installation, a limiting engagement structure is provided on the tongue 302. This limiting engagement structure engages with a limiting structure on the connector housing 1. After the shielding sleeve 3 is installed in place on the connector housing 1, the limiting engagement structure abuts against the limiting structure on the connector housing 1, thereby providing a constraint force from the connector housing 1 to limit its outward warping. This constraint force can, for example, not act on the tongue 302 before it warps outwards, but act on it when it warps, or act continuously on the tongue 302, always driving it to tend to warp inwards. Figure 1-14 In the embodiment shown, the limiting fit structure is formed by setting a limiting protrusion 304 on the tongue 302. The limiting protrusion 304 and the contact protrusion 303 mentioned above adopt an integral structure. The two are formed by two different parts of a strip protrusion on the tongue 302, thus having the advantage of being easier to process.

[0057] like Figure 1-7 , Figure 13-14 As shown, in some embodiments, the strip-shaped protrusion has a simply supported beam structure, that is, a trapezoid without a bottom edge, and its top forms the highest point of the protrusion. The part near the front end of the connector constitutes the aforementioned limiting protrusion 304, and the part near the rear end of the connector constitutes the aforementioned contact protrusion 303. In order to fix the connector to the mounting panel 2, a mating surface 104 that fits against the mounting panel 2 is provided on the connector housing 1. When the connector is installed in place on the mounting panel 2, the limiting protrusion 304 is located in front of the mating surface 104 of the connector housing, and the contact protrusion 303 is located behind the mating surface 104, that is, it extends out of the inner cavity of the connector housing 1.

[0058] Although Figure 1-7 In the illustrated embodiment, both the contact protrusion 303 and the limiting protrusion 304 are composed of two parts of the same strip-shaped protrusion. However, those skilled in the art should understand that in other embodiments, such as... Figure 15-16 As shown, the strip-shaped protrusion can also be replaced by a cantilever beam structure. In this case, one end of the cantilever beam near the tip of the tongue can be connected to the tongue, and the other end forms a cantilever structure.

[0059] Because the contact protrusion 303 and the limiting protrusion 304 have relatively high protrusion heights, they generate significant resistance when inserted into the connector housing 1. Therefore, in a preferred embodiment, to reduce this resistance, such as... Figure 13-14 As shown, a notch 105 is provided on the wall of the connector housing 1, directly opposite the contact protrusion and the limiting protrusion. When the shielding sleeve 3 is installed in place, the limiting protrusion 304 is still located in the notch 105 and is pressed against or attached to the bottom of the notch. At this time, the part in contact with the limiting protrusion 304 constitutes the aforementioned limiting structure.

[0060] In addition to generating resistance during installation to the connector housing 1, the shielding sleeve 3 also generates frictional resistance between itself and the inner wall of the mounting hole 201 during the installation of the connector to the mounting panel 2. To reduce this resistance and further reduce the resistance during the installation of the shielding sleeve 3 onto the connector housing, a notch 106 is provided on the inner side of the connector housing 1 opposite to the contact protrusion 303. This notch 106 provides a larger deformation space for the contact protrusion 303, making it easier to deform, thereby reducing the installation resistance.

[0061] In a preferred embodiment, each side of the shielding sleeve 3 is provided with a plurality of contact protrusions 303. In this case, in order to reduce the insertion resistance when the connector is installed onto the mounting panel 2, the contact protrusions 303 on each side are at least partially staggered from each other in the insertion direction of the shielding sleeve 3. For example, in Figure 1-7 In the illustrated embodiment, three contact protrusions 303 are provided on each side of the shielding sleeve 3, with the middle contact protrusion 303 positioned further forward than the two side contact protrusions. It should be noted that although the contact protrusions 303 on each side of the shielding sleeve 3 in the above embodiment are arranged in a staggered configuration, in other embodiments, the contact protrusions 303 can of course be aligned front to back. Furthermore, when the contact protrusions 303 are staggered, the staggered arrangement is not limited to the aforementioned configuration of the middle protrusion being further forward and the two side protrusions being further back.

[0062] In the above embodiments, each tongue 302 is provided with only one contact protrusion 303 and a limiting protrusion 304, which is actually determined by the width of the tongue 302. When the width of the tongue 302 is wider, in order to have sufficient contact area with the mounting panel 2, more contact protrusions 303 and limiting protrusions 304 can be provided on each tongue 302. In addition, in the above embodiments, only one tongue 302 is provided on each side of the shielding sleeve 3, while in other embodiments, when the side of the shielding sleeve is wider, multiple tongues 302 arranged side by side can be provided on each side, and correspondingly, contact protrusions and limiting protrusions are provided on each tongue.

The plug and socket are also typically referred to individually as connectors. In the connector assembly of this invention, the connector of this invention can be used as either a plug or a socket; the other of the plug or socket can be a connector adapted to the connector of this invention, which will not be elaborated here.
