Description

Technical Field

[0001] The present invention relates to a socket connector and a connector assembly, belonging to the technical field of conductive connection devices. Background Art

[0002] With the continuous development of new energy vehicles, in order to meet the demand for large current-carrying, a solution of using metal bars instead of wires has emerged. For example, a connector disclosed in the utility model patent with the authorization announcement number CN221978256U includes a plug and a socket. The plug includes a plug injection molding assembly, a female terminal assembly, an end cover, an anti-touch male pin assembly, and a female bus bar. The plug injection molding assembly includes a plug housing and a plug rubber core (i.e., a plug insulator). The plug rubber core has a cavity, and one end of the female bus bar extends into the cavity and is connected to the anti-touch male pin assembly. The socket includes a socket injection molding assembly, a male terminal assembly, and a male bus bar. The socket injection molding assembly includes a socket housing and a socket rubber core (i.e., a socket insulator) provided in the socket housing. The socket housing is used to be fixed on the installation panel of the device. The socket rubber core has a cavity, and one end of the male bus bar extends into the cavity and is connected to the male terminal assembly. When the plug and the socket are docked, the anti-touch male pin assembly can be inserted into the male terminal assembly.

[0003] The conduction method of the above-mentioned male bus bar and female bus bar can also refer to the connector, connector assembly, and wire harness product disclosed in the utility model patent with the authorization announcement number CN218770178U. The connector assembly includes a plug connector and a socket connector. The plug connector includes a plug copper bar and a plug end copper column; the socket connector includes a socket copper bar, a socket end copper column, and a nut; when the plug connector and the socket connector are connected, a locking bolt sequentially passes through the plug copper bar, the plug end copper column, the socket end copper column, and the socket copper bar and then is connected to the nut to fasten the plug end copper column and the socket end copper column together and realize the conduction of the plug copper bar and the socket copper bar.

[0004] During actual installation, first, the socket connector is fixed to the device panel, and then the socket copper bar (i.e., the socket conductive bar) of the socket connector is connected to the components inside the device. After the plug connector and the socket connector are inserted, the locking bolt is tightened. However, since the socket copper bar is fixedly arranged relative to the socket insulator, after the socket connector is fixed to the device panel, once there is a fitting error between the socket copper bar and the components inside the device, it will not be able to fit with the components inside the device to achieve a good connection. Therefore, the socket copper bar can only be connected to a flexible metal bar or a wire, and the deformable characteristics of the flexible metal bar or wire are used to compensate for the fitting error. If it is connected to a rigid metal bar or a device, the fitting error cannot be absorbed, which results in limitations on the form of the components inside the device connected to the socket copper bar. In addition, the existing plug connector and socket connector have no guidance during insertion, which is not convenient for the connection operation. Summary of the Invention

[0005] The object of the present invention is to provide a socket connector, so as to solve the problem that after the existing socket connector is fixed to the device panel, there is a fitting error between the socket conductive row and the components inside the device, resulting in that the socket conductive row can only be connected to a flexible metal row or a wire, and the application is limited; the object of the present invention is also to provide a connector assembly to solve the above problems.

[0006] To achieve the above object, the socket connector in the present invention adopts the following technical solution: A socket connector includes a socket housing for mounting on a device panel and a socket conductive row mounted on the socket housing.

The side edges of the first row body and the second row body are not aligned on at least one side in the width direction of the socket conductive bar, so as to form a stepped structure facing the connection hole at the transition position between the first row body and the second row body. A stop step for cooperating with the stepped structure to limit the backward movement limit position of the socket conductive bar is provided on the socket insulator. A stop wall for cooperating with the socket conductive bar to limit the forward movement limit position of the socket conductive bar is provided on the socket outer shell.

[0012] Furthermore, an installation hole for installing a locking bolt and a semi-cylindrical end face coaxial with the installation hole are provided at the end of the second row body. The stop wall is an arc wall adapted to the semi-cylindrical end face of the second row body.

[0013] Furthermore, a transfer post is installed in the socket housing. A cooperation hole for the locking bolt to pass through or cooperate with is provided on the transfer post.

[0014] Furthermore, a fixed seat is installed on the socket housing. The transfer post is slidably guided in the fixed seat. An anti-disengagement structure for preventing the transfer post from disengaging from the fixed seat is provided on the fixed seat.

[0015] To achieve the above object, the following technical solution is adopted for the connector assembly in the present invention: A connector assembly includes a plug connector and a socket connector.

DETAILED DESCRIPTION

[0029] In view of the technical problems existing in the prior art, the basic concept of the present invention is to change the working relationship between the socket conductive bar and the socket shell. The socket conductive bar is changed from being fixed relative to the socket shell to being floating relative to the socket shell. In this way, the socket conductive bar can fit the components in the equipment by floating, thereby achieving a better fixed connection effect.

[0030] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0031] Embodiment 1 of the connector assembly of the present invention: like Figure 1 , Figure 2 and Figure 3As shown, the connector assembly includes a plug connector and a socket connector. The socket connector includes a socket housing for mounting on the device panel 10 and a socket busbar 3 mounted on the socket housing. The socket housing includes a socket outer shell 1 and a socket insulator 2 fixedly mounted on the socket outer shell 1. The socket outer shell 1 is provided with a connection flange for fixedly connecting with the device panel 10. One end of the socket insulator 2 is inserted into the socket outer shell 1, and the rest is located outside the socket outer shell 1. When the socket connector is mounted on the device panel 10, this part passes through the device panel 10 and extends into the device interior.

[0032] The socket housing has a mounting cavity for mounting the socket busbar 3, and this mounting cavity is jointly formed by the space inside the socket insulator 2 and the space inside the socket outer shell 1. One end of the socket busbar 3 is exposed inside the device, and a connection hole 3-3 penetrating the socket busbar 3 is provided for connecting with the device internal components (in this embodiment, it is the device internal busbar 11, and it is a rigid metal busbar). The socket outer shell 1 is provided with a vertically penetrating connection cavity 1-3. The other end of the socket busbar 3 extends out of the socket insulator 2, passes through a part of the socket outer shell 1, and extends into the connection cavity 1-3.

[0033] There is a floating gap between the socket busbar 3 and the mounting cavity for the socket busbar 3 to float along the penetrating direction of the connection hole 3-3. In this way, when there is a fitting error between the socket busbar 3 and the device internal busbar 11, the socket busbar 3 can absorb the fitting error between the two through floating, realize fitting with the device internal busbar 11, and thus achieve a better fixed connection effect.

[0034] In this embodiment, the socket busbar 3 is a busbar with a consistent thickness direction everywhere. The thickness direction is the up and down direction, the length direction is the front and back direction, and the width direction is the left and right direction. Figure 4 As shown, for the socket insulator 2, the cavity wall of its mounting cavity includes an upper limiting wall 2-1 and a lower limiting wall 2-2 that are parallel up and down. An upper floating gap 2-3 is formed between the upper end face of the socket busbar 3 and the upper limiting wall 2-1, and a lower floating gap 2-4 is formed between the lower end face of the socket busbar 3 and the lower limiting wall 2-2. The part of the socket outer shell 1 through which the busbar 3 passes has a through hole, and the upper and lower hole walls of the through hole are also arranged in parallel, and upper and lower floating gaps are respectively formed between them and the upper and lower end faces of the socket busbar 3 to ensure that the socket busbar 3 can float up and down.

[0035] To prevent the socket conductive bar 3 from moving unrestrictedly before installation of the socket connector (e.g., during transportation), an elastic pressing body (not shown in the figure) for respectively pressing against the two end faces (i.e., the upper and lower end faces) in the thickness direction of the socket conductive bar 3 can be connected to the cavity wall of the installation cavity (including the upper limit wall 2-1, the lower limit wall 2-2, and the upper and lower hole walls of the above-mentioned perforation) to achieve pre-fixing of the socket conductive bar 3. The elastic pressing body can specifically be an elastic claw or an elastic bulge. Since the elastic pressing body can be compressed, after the socket connector is installed, it will not affect the up and down floating of the socket conductive bar 3.

[0036] To restrict the movement of the socket conductive bar 3 in other directions, such as Figure 5 and Figure 6 As shown, there are two socket conductive bars 3, and three side limit walls 2-6 are provided on the socket insulator 2. An adjacent two side limit walls 2-6 are used to accommodate one socket conductive bar 3, and the two side limit walls 2-6 on both sides can restrict the left and right movement of the socket conductive bar 3. Additionally, in combination with Figure 7 As shown, the socket conductive bar 3 includes a first row body 3-1 and a second row body 3-2 that are integrally connected. The above-mentioned connection hole 3-3 is provided on the first row body 3-1. The two side edges of the first row body 3-1 and the second row body 3-2 in the width direction of the socket conductive bar 3 are not aligned, so that two step structures are formed at the transition position between the first row body 3-1 and the second row body 3-2, and one of the step structures 3-4 faces the direction of the connection hole 3-3. A stop step 2-5 ( Figure 6 shown) that is in stop cooperation with the step structure 3-4 to limit the backward movement limit position of the socket conductive bar 3 is provided on the socket insulator 2. At the same time, a stop wall that is in stop cooperation with the socket conductive bar 3 to limit the forward movement limit position of the socket conductive bar 3 is provided on the socket housing 1, so as to prevent the socket conductive bar 3 from moving back and forth in the socket housing.

[0037] Specifically in this embodiment, as Figure 7 shown, an installation hole 3-5 for installing the locking bolt 6 and a semi-cylindrical end face 3-6 coaxial with the installation hole 3-5 are provided at the end of the second row body 3-2. The above-mentioned stop wall is an arc wall adapted to the semi-cylindrical end face 3-6 of the second row body 3-2. As Figure 5 shown, this can not only achieve stopping but also facilitate the insertion of the second row body 3-2 into the socket housing 1 for convenient assembly. Moreover, there are also side limit walls in the socket housing 1 that can restrict the left and right movement of the socket conductive bar 3.

[0038] As Figure 2 , Figure 3 and Figure 8As shown, a transfer post 5 is installed inside the socket housing 1. A mating hole for the locking bolt 6 to pass through is provided on the transfer post 5. The socket busbar 3 has a first mating surface (i.e., a part of the upper end surface of the socket busbar 3) that fits against one side end surface (i.e., the lower side end surface) of the transfer post 5. The transfer post 5 is arranged to be floatingly movable in the socket housing 1 in a direction perpendicular to the first mating surface (i.e., the up and down direction). In this way, when the socket busbar 3 moves upward to connect with the busbar 11 inside the device, the socket busbar 3 can push the transfer post 5 upward; when the socket busbar 3 moves downward to connect with the busbar 11 inside the device, the transfer post 5 can move downward, so that the lower side end surface is in contact with the upper end surface of the socket busbar 3 in a fitting manner.

[0039] Furthermore, a fixed seat 4 is fixedly installed on the socket housing 1. The transfer post 5 is arranged to be guidingly slidable inside the fixed seat 4, which facilitates the up and down floating movement of the transfer post 5. A anti-disengagement structure for preventing the transfer post 5 from disengaging upward from the fixed seat 4 is provided on the fixed seat 4. The anti-disengagement structure can be in various forms. For example, a limit protrusion can be provided on the fixed seat 4, and a vertically extending limit groove can be provided on the transfer post 5. The limit protrusion extends into the limit groove. When the transfer post 5 moves upward to the limit position, the groove wall at the lower end of the limit groove engages with the limit protrusion to prevent the transfer post 5 from disengaging. Of course, the anti-disengagement structure can also be a flange provided at the upper end of the fixed seat 4 and extending inward. When the transfer post 5 moves upward to the limit position, the upper end surface of the transfer post 5 engages with the flange.

[0040] As Figure 1 , Figure 2 , Figure 3 , Figure 8 As shown, the plug connector includes a plug housing 7 and a plug busbar 8 installed on the plug housing 7. During installation, the plug connector is inserted into the socket connector from top to bottom. The plug busbar 8 has a second mating surface for fitting against the other side end surface (i.e., the upper side end surface) of the transfer post 5. A nut 9 that can move in a direction perpendicular to the first mating surface or the second mating surface (i.e., the up and down direction) is provided inside the plug housing 7. The outer peripheral surface of the nut 9 is in anti-rotation fit with the plug housing 7. The locking bolt 6 passes through the socket busbar 3, the transfer post 5, the plug busbar 8 from bottom to top and is connected to the nut 9. By operating to rotate the locking bolt 6 in the connection cavity 1-3, since the nut 9 can only move up and down, under the principle of the screw-nut mechanism, the nut 9 moves downward and presses the plug busbar 8 into contact with the transfer post 5, realizing the pressing and conduction among the plug busbar 8, the transfer post 5, and the socket busbar 3.

[0041] Further, when the adapter post 5 moves upward to the extreme position, its upper end face still does not protrude from the fixed seat 4, which can prevent the human hand from accidentally touching the adapter post 5 and play a protective role. Of course, an anti-touch sleeve with an upper end higher than the upper end face of the adapter post 5 can be installed on the adapter post 5 at the same time to improve the anti-touch effect. Based on this, a boss 8-1 for extending into the fixed seat 4 is provided on the plug conductive row 8, and the second joint surface is the lower end face of the boss 8-1, ensuring that the plug conductive row 8 can be in contact with the adapter post 5. As Figure 9 shown, the boss 8-1 is annular, and the inner hole in the center is for the locking bolt 6 to pass through.

[0042] The plug housing 7 and the socket housing 1 are guided and matched through the guide posts and guide holes and the guide posts and guide grooves during mating insertion, so as to facilitate the mating insertion assembly. Specifically, as Figure 1 , Figure 2 , Figure 3 and Figure 10 shown, the guide posts include a convex post 1-1 protruding from the socket housing 1 and integrally connected to the socket housing 1 on one side. The guide posts also include two parallel and spaced cylindrical columns 7-2 located on the plug housing 7. Two guide holes 1-2 for guiding and mating with the cylindrical columns 7-2 are provided on the socket housing 1, and a guide groove 7-1 for guiding and mating with the convex post 1-1 is also provided on the plug housing 7. The guide groove 7-1 and the two cylindrical columns 7-2 are arranged in a triangular shape, so that after the plug connector and the socket connector are mated, the two cylindrical columns 7-2 and the convex post 1-1 are arranged in a triangular shape. The end of the cylindrical column 7-2 is provided with a chamfer structure to facilitate guiding the mating insertion, realizing the absorption of normal tolerance, and the cooperation between the guide groove 7-1 and the convex post 1-1 can correct the angular tolerance.

[0043] In this embodiment, the plug conductive row 8 is fixedly arranged relative to the plug housing 7. When the locking bolt 6 is rotated to make the nut 9 move downward, the downward pressure of the nut 9 on the plug conductive row 8 causes the plug housing 7 to move downward synchronously, and the plug connector will be inserted more tightly. This requires that there is enough mating insertion stroke between the plug connector and the socket connector to ensure that the plug conductive row 8, the adapter post 5, and the socket conductive row 3 can be tightly squeezed before the plug connector is inserted to the bottom.

[0044] When the connector assembly of the present invention is assembled, first, the socket housing 1 of the socket connector is fixed on the device panel 10, and then the socket conductive row 3 is connected to the conductive row 11 inside the device. During the connection process, the socket conductive row 3 can be closely attached to the conductive row 11 inside the device through floating. Then, the plug connector is inserted into the socket connector under the guidance of the mating and guiding structure, and then the locking bolt 6 is installed. The locking bolt 6 passes through the socket conductive row 3, the adapter post 5, and the plug conductive row 8 and is connected in cooperation with the nut 9. The locking bolt 6 is tightened, so that the nut 9 moves downward to press the plug conductive row 8, the adapter post 5, and the socket conductive row 3 to achieve reliable connection. Among them, the socket conductive row 3 in the socket connector is pre-fixed through the elastic pressing body, which is beneficial to the modular customization of the connector.

[0045] Embodiment 2 of the connector assembly in the present invention: Different from Embodiment 1, as Figure 11 shown, the socket insulator is two half-insulators arranged along the thickness direction (i.e., the up and down direction) of the socket conductive row. One of the half-insulators or both half-insulators are provided with accommodation grooves for accommodating the socket conductive row. The two half-insulators are joined together to jointly form an installation cavity on the socket insulator. And a limiting post 2-7 penetrating the socket conductive row is provided in the accommodation groove. A perforation for the limiting post 2-7 to pass through is opened on the socket conductive row. The limiting post 2-7 is integrally connected with one of the half-insulators. At this time, when installing the socket conductive row, directly place the socket conductive row into the accommodation groove of one of the half-insulators, and then join the two half-insulators together. During the process, ensure that the limiting post 2-7 passes through the perforation on the socket conductive row. Finally, install the two half-insulators and the socket conductive row together into the plug housing, and the two half-insulators can be fixed to the socket housing through buckles respectively.

[0046] Embodiment 3 of the connector assembly in the present invention: Different from Embodiment 2, instead of opening a perforation on the socket conductive row, a notch is provided on the edge. At this time, the limiting post penetrates the notch on the edge of the socket conductive row, and the outer peripheral surface of the limiting post is adapted to the shape of the notch. For example, when the limiting post is cylindrical, the notch is semi-circular; when the limiting post is a quadrangular prism, the notch is U-shaped.

[0047] Embodiment 4 of the connector assembly in the present invention: Different from Embodiment 1, a rigid limiting body is connected to the cavity wall of the installation cavity of the socket housing. The rigid limiting body is used to cooperate with the two end faces in the thickness direction of the socket conductive row to temporarily limit the floating of the socket conductive row. The rigid limiting body is detachable or can be destroyed. For example, the rigid limiting body is a small rib, and the connection position with the cavity wall is relatively weak. It can be broken off with a tool. At this time, the rigid limiting body can be destroyed before connecting the socket conductive row to the components inside the device. Of course, if the rigid limiting body limits the edge position of the socket conductive row, it does not have to be destroyed before connection. During the connection process, the rigid limiting body can be destroyed by the extrusion force when the socket conductive row floats. Of course, the rigid limiting body can also be a top screw threadedly assembled on the socket housing. The top screw penetrates the side wall of the socket housing and extends into the installation cavity and temporarily abuts against the end face of the socket conductive row. At this time, the rigid limiting body needs to be removed before connecting the socket conductive row to the components inside the device.

[0048] Embodiment 5 of the connector assembly in the present invention: Different from Embodiment 1, the plug housing has an assembly cavity for assembling the plug conductive row. There is a moving gap between the plug conductive row and the assembly cavity for the plug conductive row to move closer to the socket conductive row. At this time, when the nut presses the plug conductive row to move, only the plug conductive row moves, and the plug housing no longer moves with it.

[0049] In other embodiments of the connector assembly: The plug housing and the socket housing can be inserted and guided only through the cooperation of the guide posts and the guide holes or only through the cooperation of the guide posts and the guide grooves.

[0050] In other embodiments of the connector assembly: No additional guide posts are provided. At this time, no corresponding guide holes and / or guide grooves are provided either. At this time, only the plug housing and the socket housing itself are used for guiding.

[0051] In other embodiments of the connector assembly: The fixed seat may not be installed on the socket housing. At this time, the adapter post is directly guided and assembled in the socket housing, and the corresponding anti-disengagement structure is provided on the socket housing. In addition, at this time, the end face of the adapter post may protrude from the socket housing. At this time, there is no need to provide a boss on the plug conductive row. Of course, the end face of the adapter post may not protrude from the socket housing. At this time, a boss still needs to be provided on the plug conductive row to extend into the socket housing and contact the adapter post.

[0052] In other embodiments of the connector assembly: The nut can be arranged in the socket housing. At this time, the locking bolt is assembled from one side of the plug housing.

[0053] In other embodiments of the connector assembly: The nut may not be provided. In this case, the adapter post and the plug conductive row, and the adapter post and the socket conductive row are respectively connected by independent locking bolts. The two conductive rows still press against the two end faces of the adapter post. In this case, the mating holes on the adapter post are threaded holes.

[0054] In other embodiments of the connector assembly: The end face of the second row body may be a flat surface. In this case, the stop wall is also flat.

[0055] In other embodiments of the connector assembly: The first row body and the second row body may be misaligned only on one side in the width direction of the socket conductive row, as long as a stepped structure can be formed.

[0056] In other embodiments of the connector assembly: The socket conductive row may be a straight-extending conductive row, that is, both sides in the width direction of the socket conductive row are straight-extending. In this case, the front-back and left-right limits of the socket conductive row in the socket housing can rely on limit pins. Of course, in this case, a split socket insulator needs to be provided. Of course, it can also rely on locking bolts. In this case, the insulator is integral. The locking bolt is threadedly connected to the adapter post, and the locking bolt is directly pre-installed on the socket connector. Since the locking bolt passes through the socket conductive row, it can limit it.

[0057] In other embodiments of the connector assembly: The elastic pressing body is no longer connected to the cavity wall of the installation cavity, and the rigid limiting body is no longer connected either. In this case, the socket conductive row can float freely along the through direction of the connection hole.

[0058] In other embodiments of the connector assembly: The socket conductive row may be a bent L-shaped conductive row. In this case, the thickness directions of the two parts of the L-shaped conductive row are perpendicular. In this case, the socket conductive row floats along the through direction of the connection hole, and can still adjust the distance from the components in the device. In other embodiments, the socket conductive row may also be a multi-bent conductive row, such as a Z-shaped conductive row, and the effect is the same.

[0059] In other embodiments of the connector assembly: The components in the device may also be rigid component devices. Of course, they may also be flexible metal rows or wires.

[0060] In other embodiments of the connector assembly: The socket housing may be an integrally injection-molded housing, and is no longer divided into a socket outer shell and a socket insulator. In this case, the installation cavity is provided on the integral socket housing.

[0061] The embodiment of the socket connector in the present invention is: The specific structure of the socket connector is the same as that of the socket connector in the above-mentioned connector assembly embodiment, and will not be repeated here.

[0062] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. The scope of patent protection of the present invention is subject to the claims. All equivalent structural changes made by using the content of the specification and drawings of the present invention should, by the same token, be included within the protection scope of the present invention.
