For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0083] A connector includes a connector housing and conductive terminals disposed within the connector housing. The conductive terminals are used for soldering to a circuit board. In related technologies, the connector housing typically includes a plastic housing and a shielding housing connected within the plastic housing. The shielding housing is suitable for mounting the outer side of the conductive terminals and serves as electromagnetic shielding. During the production process, the plastic housing and the shielding housing need to be subjected to high-temperature furnace treatment along with the circuit board, with temperatures typically exceeding 200°C. Because the plastic housing is a soft material and the shielding housing is a metal material, when the shielding housing is connected inside the plastic housing, the plastic housing is prone to deformation and detachment from the shielding housing during the high-temperature furnace treatment. Consequently, after the high-temperature furnace treatment, the connection between the plastic housing and the shielding housing is prone to loosening, resulting in a smaller separation force between the plastic housing and the shielding housing, which affects the performance and reliability of the connector.
[0084] Based on the above analysis, this application provides a connector housing. Specifically, the connector housing is used in connectors, which in practical applications can be board-end connectors, wire-end connectors, etc. The connector housing of this application will be described in detail below with reference to the accompanying drawings.
[0085] Referring to Figures 1-19, the connector housing 6 provided in this embodiment may specifically include a plastic housing 1 and a shielding housing 2. The shielding housing 2 is sleeved on the outside of a portion of the plastic housing 1, and at least a portion of the shielding housing 2 extends into the interior of the plastic housing 1. The portion of the shielding housing 2 extending into the interior of the plastic housing 1 is suitable for mounting conductive terminals 3.
[0086] Specifically, one end of the plastic housing 1 is provided with a mating interface, which is suitable for insertion with a mating connector. A portion of the shielding housing 2 extends into the interior of the plastic housing 1 from the other end, and a conductive terminal 3 is provided inside this portion to realize the electrical connection between the conductive terminal 3 and the mating terminal of the mating connector.
[0087] In this embodiment, by fitting the shielding shell 2 onto the outside of a portion of the plastic shell 1, the connection between the plastic shell 1 and the shielding shell 2 is located inside the shielding shell 2. Compared to the connection between the plastic shell 1 and the shielding shell 2 being located outside the shielding shell 2, the deformation of the plastic shell 1 due to thermal expansion and contraction is limited to the inside of the shielding shell 2. The deformation at the connection is smaller, the connection gap is smaller, the connection is more secure, and a greater release force is required, thereby improving the performance and reliability of the connector.
[0088] In some embodiments of this application, the plastic housing 1 includes a body portion 11 and an extension portion 10 connected to each other; the shielding housing 2 is sleeved on the outside of the extension portion 10, and a portion of the shielding housing 2 extends into the interior of the body portion 11.
[0089] Specifically, as shown in Figures 2-4, an extension portion 10 extends outward from the main body 11 of the plastic shell 1. The extension portion 10 and the main body 11 are integrally formed. The main body 11 can be any shape such as square or round. There can be at least two extension portions 10. The two extension portions 10 are respectively disposed on two opposite side walls of the main body 11, and the two extension portions 10 are symmetrically arranged. The presence of at least two extension portions 10 can ensure the reliability of the connection between the plastic shell 1 and the shielding shell 2.
[0090] In practical applications, by placing the extension 10 of the plastic housing 1 inside the shielding housing 2, the contact area between the shielding housing 2 and the plastic housing 1 is reduced. The smaller contact area further reduces the amount of deformation at the connection point. Even if deformation occurs, the shielding housing 2 can effectively limit this deformation. At the same time, the smaller extension 10 is easier to be completely covered by the shielding housing 2. The amount of deformation at the connection point is smaller, the connection gap is smaller, the connection is more secure, and the required release force is greater, thereby improving the performance and reliability of the connector.
[0091] In some embodiments, the shielding housing 2 includes a first shielding housing 21 and a second shielding housing 22; the first shielding housing 21 is sleeved on the outside of the extension 10; the second shielding housing 22 is connected to the extension 10 and the first shielding housing 21, and at least a portion of the second shielding housing 22 extends into the interior of the body portion 11.
[0092] As shown in Figures 1-3, the shielding housing 2 can be divided into two shielding parts, namely the first shielding housing 21 and the second shielding housing 22. The first shielding housing 21 is sleeved on the outside of the extension 10. The second shielding housing 22 has an installation channel inside, which is suitable for passing through the conductive terminal 3. A part of the second shielding housing 22 is disposed inside the main body 11, and another part of the second shielding housing 22 is disposed outside the main body 11. The part of the second shielding housing 22 disposed outside the main body 11 is connected to the extension 10 and the first shielding housing 21, thereby realizing the mutual connection of the plastic housing 1, the first shielding housing 21 and the second shielding housing 22.
[0093] In this embodiment, by dividing the shielding housing 2 into two parts, during assembly, the second shielding housing 22 can be assembled with the plastic housing 1 first, and then the first shielding housing 21 can be assembled with the second shielding housing 22. This simplifies the structure of the shielding housing 2 and facilitates the assembly process of the connector housing 6. The first shielding housing 21 is sleeved on the outside of the extension 10, which can reduce the deformation of the connection between the plastic housing 1 and the shielding housing 2, improve the release force, and thus improve the reliability and performance of the connector.
[0094] In some embodiments of this application, the first shielding housing 21 is open on the side near the extension 10, and closed on the side away from the extension 10.
[0095] Specifically, as shown in Figures 1-2 and 10, the first shielding shell 21 can be a rectangular structure formed by multiple side walls. The side of the rectangular structure near the extension 10 is an open end, and the side wall away from the extension 10 is a closed end. As shown in Figure 21, an abutment surface is formed on the conductive terminal 3. The abutment surface is adapted to abut against the shielding member to shield the interference of the conductive terminal 3. The abutment surface of the conductive terminal 3 may include a first abutment surface 320 and a second abutment surface 330.
[0096] In practical applications, the side wall of the closed end of the first shielding housing 21 can abut against the first contact surface 320 of the conductive terminal 3 located inside the second shielding housing 22. Thus, the interference of the conductive terminal 3 can be shielded by the closed end of the first shielding housing 21 without the need to set more shielding sheets, which can reduce costs.
[0097] In some embodiments, the second shielding shell 22 includes a shielding shell body 221 and a plurality of shielding sleeves 222 connected to each other, the shielding sleeves 222 passing through the interior of the body portion 11; the shielding shell body 221 abuts against the outer wall of the body portion 11 and is connected to the extension portion 10; the first shielding shell 21 is sleeved on the outside of the extension portion 10 and the shielding shell body 221.
[0098] Specifically, as shown in Figures 1-19, multiple shielding sleeves 222 are arrayed on the shielding shell body 221. The shielding sleeves 222 are hollow columnar structures and are connected to the shielding shell body 221. The shielding sleeves 222 and the shielding shell body 221 are used to form an installation channel, which is used to pass through the conductive terminals 3.
[0099] While the shielding sleeve 222 is inserted into the interior of the main body 11, the shielding shell body 221 abuts against the outer wall of the main body. The shielding shell body 221 is inserted into or snapped into the extension 10. The first shielding shell 21 is sleeved on the outside of the extension 10 and the shielding shell body 221. On the one hand, the first shielding shell 21 can simultaneously restrict the movement of the second shielding shell 22 and the extension 10, improving the reliability of the connector housing 6. On the other hand, the first shielding shell 21 and the shielding shell body 221 can make multiple surfaces of the extension 10 surrounded by metal, so that the deformation of the extension 10 in any direction can be restricted by the shielding shell 2, further reducing the deformation of the connection between the plastic housing 1 and the shielding shell 2, improving the release force, and improving the performance and reliability of the connector.
[0100] In some embodiments, the shielding shell body 221 is provided with a first insertion portion 2210 corresponding to the position of the extension 10; the inner wall of the first shielding shell 21 is provided with a second insertion portion 211; the extension 10 is inserted into the first insertion portion 2210 along the first direction Z; the second insertion portion 211 is inserted into the extension 10 and the first insertion portion 2210 along the second direction Y; wherein the first direction Z and the second direction Y intersect.
[0101] Specifically, the first direction Z is the Z-axis direction as shown in Figure 3, and the second direction Y is the Y-axis direction as shown in Figure 3. The first direction Z specifically refers to the direction in which the plastic shell 1 is inserted into the first shielding shell 21. The first direction Z intersects with the second direction Y, and preferably, the first direction Z and the second direction Y are perpendicular. The first direction Z and the second direction Y are applicable in all the following embodiments.
[0102] As shown in Figures 2-19, the extension 10 extends outward from the main body 11 along the first direction Z, the first insertion part 2210 extends along the first direction Z on the shielding shell body 221, and the second insertion part 211 extends along the second direction Y on the inner wall of the first shielding shell 21. The extension 10 can be inserted into the shielding shell body 221 in the first direction Z, so that the plastic shell 1 is connected to the shielding shell body 221. The second insertion part 211 can be inserted into the extension 10 and the first insertion part 2210 along the second direction Y, so that the first shielding shell 21 is simultaneously connected to the plastic shell 1 and the shielding shell body 221. In practical applications, by setting the first insertion part 2210 and the second insertion part 211, the movement of the plastic shell 1 and the first shielding shell 21 in any direction can be restricted, thereby improving the connection reliability between the shielding shell 2 and the plastic shell 1.
[0103] In some embodiments, the extension 10 includes a plug post 101 extending along a first direction Z; the first plug-in portion 2210 includes a first slot 22101 extending along the first direction Z; the plug post 101 is inserted into the first slot 22101. Specifically, the plug post 101 is a rectangular columnar structure extending along the first direction Z, and the first slot 22101 is a rectangular groove structure extending along the first direction Z. The plug post 101 is inserted into the first slot 22101 to realize the mating insertion of the extension 10 and the shielding shell 2. In this way, by mating the plug post 101 and the first slot 22101, the contact area between the extension 10 and the shielding shell body 221 can be increased, and the reliability of the connection between the plastic shell 1 and the second shielding shell 22 can be improved.
[0104] In some embodiments of this application, the plug post 101 is provided with a first protrusion 102 protruding along a third direction X, the third direction X intersecting with the first direction Z and the second direction Y; the first plug part 2210 further includes a second protrusion 22102 protruding along a third direction X, the first protrusion 102 and the second protrusion 22102 being aligned in the second direction Y; the second plug part 211 includes a second slot 2111 extending along the second direction Y; the first protrusion 102 and the second protrusion 22102 are inserted into the second slot 2111.
[0105] As shown in Figures 2-8, specifically, a first protrusion 102 is provided at the middle position or the tail end of the insertion post 101. The first protrusion 102 protrudes along the third direction X. A second protrusion 22102 is correspondingly provided at the middle position or the tail end of the first slot 22101. The third direction X is the X-axis direction as shown in Figure 3. The third direction X intersects the first direction Z and the second direction Y in pairs. Preferably, the third direction X is perpendicular to the first direction Z and the second direction Y in pairs. The second protrusion 22102 protrudes along the third direction X. The shapes of the first protrusion 102 and the second protrusion 22102 are adapted to the shape of the second slot 2111 and can both be rectangular. The first protrusion 102 and the second protrusion 22102 are aligned in the second direction Y. In this way, the first protrusion 102 and the second protrusion 22102 can be inserted into the second slot 2111 at the same time.
[0106] In practical applications, the first protrusion 102 and the second protrusion 22102 are simultaneously inserted into the second slot 2111. The first shielding shell 21 can simultaneously fix the extension 10 and the shielding shell body 221 in the second direction Y. This can increase the connection area between the plastic shell 1, the first shielding shell 21 and the second shielding shell 22, restrict the movement of the plastic shell 1 and the first shielding shell 21, and improve the reliability of the connection between the plastic shell 1 and the shielding shell 2.
[0107] In other embodiments, as shown in Figures 2-10, there can be two second protrusions 22102. The two second protrusions 22102 are respectively disposed on both sides of the middle part or the tail end of the first slot 22101 along the second direction Y. The first protrusion 102 is disposed between the two second protrusions 22102. The two second protrusions 22102 and the first protrusion 102 are all inserted into the interior of the second slot 2111. The middle part or the tail end of the first slot 22101 is correspondingly provided with the second protrusions 22102, which can further increase the connection area between the plastic shell 1, the first shielding shell 21 and the second shielding shell 22, restrict the movement of the plastic shell 1 and the first shielding shell 21, and improve the reliability of the connection between the plastic shell 1 and the shielding shell 2.
[0108] In some embodiments, as shown in Figures 2-10, a boss 103 is provided on one side of the first protrusion 102 along the first direction Z; a first flange 22103 is provided on one side of the second protrusion 22102 along the first direction Z; the boss 103 contacts the second slot 2111, and the second protrusion 22102 is press-fitted with the second slot 2111 through the first flange 22103.
[0109] Specifically, the boss 103 is disposed on the side of the first protrusion 102 near the body portion 11 along the first direction Z. The boss 103 can be a rectangular protrusion or a dot. The first flange 22103 is disposed on the side of the second protrusion 22102 near the body portion 11 along the first direction Z. The first flange 22103 is a strip-shaped protrusion post, and the amount of protrusion is specifically set according to the actual situation. For example, the amount of protrusion can not exceed 0.3 mm. In the first direction Z, the first protrusion 102 can be press-fitted with the second slot 2111 through the boss 103. 2. The boss 103 can be interference-fitted with the second slot 2111. This reduces the gap between the first protrusion 102 and the second protrusion 22102 and the second slot 2111, thus reducing the dimensional tolerance transfer between the plastic housing 1 and the first shielding housing 21, and between the first shielding housing 21 and the second shielding housing 22. This, in turn, reduces dimensional tolerances and improves the reliability of the planes between the plastic housing 1 and the first shielding housing 21, and between the first shielding housing 21 and the second shielding housing 22. Furthermore, by providing the boss 103, the surface contact between the first protrusion 102 and the second slot in the insertion direction becomes a point contact, making it easier to limit wobbling along the first direction Z.
[0110] In addition, during the high-temperature furnace process, the boss 103 can soften and fill the gap between the plastic shell 1 and the first shielding shell 21, and reduce the deformation of the extension 10, so that the extension 10 and the first shielding shell 21 can reliably abut against each other after the high-temperature furnace exit, further improving the reliability of the connection between the plastic shell 1 and the first shielding shell 21.
[0111] In other embodiments, the plug post 101 is provided with a recessed portion 104 recessed along the second direction Y; the second plug portion 211 includes a third protruding portion 2112 protruding along the second direction Y; the third protruding portion 2112 is inserted into the recessed portion 104.
[0112] As shown in Figures 12 and 13, a board-end connector housing 6 according to a second embodiment of this application is provided. The structure differs from that of the first embodiment in that the insertion post 101 is provided with a recessed portion 104 recessed along the second direction Y, and the second insertion portion 211 is a third protruding portion 2112 protruding in the second direction Y. By inserting the third protruding portion 2112 into the recessed portion 104, the insertion of the extension portion 10 into the shielding shell body 221 is realized, which can simplify the connection structure between the second shielding shell 22 and the plastic shell 1 and reduce costs.
[0113] In some embodiments, the first insertion portion 2210 further includes a pin 22104 extending along the second direction Y; the second insertion portion 211 includes a pin hole 2113 disposed along the second direction Y, and the pin 22104 is inserted into the pin hole 2113.
[0114] As shown in Figures 14-15, a board-end connector housing 6 according to a third embodiment of this application is provided. The structure differs from that of the first embodiment in that its first insertion part 2210 is a pin post 22104 arranged along the second direction Y, and the corresponding second insertion part 211 is a pin hole 2113 arranged along the second direction Y. The pin hole 2113 is inserted into the pin post 22104, realizing the insertion between the first shielding housing 21 and the second shielding housing 22. This simplifies the connection structure between the first shielding housing 21 and the second shielding housing 22 and reduces costs.
[0115] In some embodiments, the main body 11 is provided with a plurality of mounting holes 110, and a shielding sleeve 222 passes through a mounting hole 110; wherein, the shielding sleeve 222 is provided with a second flange 2222, and the shielding sleeve 222 is interference-fitted with the mounting hole 110 through the second flange 2222.
[0116] Specifically, the main body 11 has a plurality of arrayed mounting holes 110 on its side wall along the first direction Z. A shielding sleeve 222 passes through a mounting hole 110. Each shielding sleeve 222 has a second flange 2222 at the end that contacts the mounting hole 110. The second flange 2222 protrudes in the second direction Y. In this way, the second flange 2222 on the shielding sleeve 222 can be interference-fitted with the end face of the mounting hole 110, thereby improving the reliability of the connection between the shielding sleeve 222 and the main body 11, and thus improving the reliability of the connection between the plastic shell 1 and the second shielding shell 22.
[0117] In some embodiments, both the first shielding housing 21 and the second shielding housing 22 are provided with a welding part 23, which is adapted to be welded to the circuit board 4.
[0118] Specifically, as shown in Figures 16-17, a board-end connector housing 6 according to the fourth embodiment of this application is provided. The structure differs from that of the first embodiment in that the welding part 23 can be a welding surface 231 or a welding post 230. The welding part 23 can include multiple welding surfaces 231 and multiple welding posts 230. The multiple welding surfaces 231 and multiple welding posts 230 are respectively disposed on the bottom surfaces of the first shielding housing 21 and the second shielding housing 22 in contact with the circuit board 4. The circuit board 4 is provided with connection holes and welding points. The welding posts 230 pass through the connection holes and are welded to the circuit board 4. The welding surfaces 231 are welded to the welding points of the circuit board 4. In practical applications, disposing of the welding parts 23 on the first shielding housing 21 and the second shielding housing 22 can improve the reliability of the connection between the first shielding housing 21 and the second shielding housing 22 and the circuit board 4.
[0119] It should be noted that the number of multiple welding surfaces 231 and multiple welding pillars 230 can be specifically set according to the actual situation, and this application embodiment does not make specific limitations in this regard.
[0120] In summary, the connector housing 6 of this application embodiment may include at least the following advantages:
[0121] In this embodiment, by fitting the shielding shell 2 onto the outside of a portion of the plastic shell 1, the connection between the plastic shell 1 and the shielding shell 2 is located inside the shielding shell 2. Compared to the connection between the plastic shell 1 and the shielding shell 2 being located outside the shielding shell 2, the deformation of the plastic shell 1 due to thermal expansion and contraction is limited to the inside of the shielding shell 2. The deformation at the connection is smaller, the connection gap is smaller, the connection is more secure, and a greater release force is required, thereby improving the performance and reliability of the connector.
[0122] This application embodiment also provides a connector 7, as shown in FIG18. The connector 7 may specifically include the connector housing 6 of any of the above embodiments. Referring to FIG18-FIG22, the connector 7 in the figures may specifically include the connector housing 6 and conductive terminals 3 of any of the above embodiments; the conductive terminals 3 are disposed inside the connector housing 6. Further, the conductive terminals 3 include metal terminals 30 and insulators 31, with the insulators 31 covering the outside of the metal terminals 30.
[0123] Specifically, the connector housing 6 has a mating interface at one end along the first direction Z, which is suitable for insertion into a mating connector. The metal terminal 30 can be inserted into or encapsulated in an insulator 31, which can support the metal terminal 30. The first shielding housing 21 of the connector housing 6 includes a shielding housing body 221 and multiple shielding sleeves 222 connected to each other. The multiple shielding sleeves 222 are arrayed on the shielding housing body 221 and are connected to the shielding housing body 221. The shielding housing body 221 includes multiple sidewalls arranged opposite each other along the third direction X. An installation channel is formed between two sidewalls of the shielding sleeves 222 and the shielding housing body 221 arranged opposite each other along the third direction X. One end of the conductive terminal 3 passes through the shielding sleeve 222 and the other end is clamped between the two opposite sidewalls. One end of the conductive terminal 3 extends out from the installation channel and connects to the circuit board 4, and the other end is suitable for electrical connection with the mating terminal of the mating connector.
[0124] It should be noted that in this embodiment, the structure of the connector housing 6 is the same as that of the connector housing 6 in any of the above embodiments, and its beneficial effects are similar, so it will not be described in detail here.
[0125] In some embodiments, the conductive terminal 3 includes at least one first conductive terminal 32 and at least one second conductive terminal 33, and the connector 7 further includes a shielding sheet 5. The first conductive terminal 32 and the second conductive terminal 33 are spaced apart within the connector housing 6. The shielding sheet 5 is connected within the connector housing 6 and is disposed between the first conductive terminal 32 and the second conductive terminal 33.
[0126] Specifically, the conductive terminal 3 may include a first conductive terminal 32 and a second conductive terminal 33. The difference between the first conductive terminal 32 and the second conductive terminal 33 is the length. The first conductive terminal 32 is a long conductive terminal, and the second conductive terminal 33 is a short conductive terminal. There may be multiple first conductive terminals 32 and second conductive terminals 33. The specific selection can be made according to the actual situation. In this embodiment, two first conductive terminals 32 and two second conductive terminals 33 are used as an example.
[0127] One end of each of the two first conductive terminals 32 is disposed in the two upper shielding sleeves 222 in the second direction Y, and the other end of each of the two first conductive terminals 32 is sandwiched between the two side walls of the shielding shell body 221 that are arranged opposite to each other in the third direction X. One end of each of the two second conductive terminals 33 is disposed in the two lower shielding sleeves 222 in the second direction Y, and the other end of each of the two second conductive terminals 33 is sandwiched between the two side walls of the shielding shell body 221 that are arranged opposite to each other in the third direction X. This can isolate the adjacent first conductive terminals 32 and second conductive terminals 33, thereby improving the shielding effect between the conductive terminals 3.
[0128] The shielding sheet 5 is connected to the shielding shell body 221 and is located inside the two second conductive terminals 33 and the two first conductive terminals 32. The shielding sheet 5 is a metal sheet, which can shield electromagnetic interference generated between the first conductive terminals 32 and the second conductive terminals 33. Furthermore, only one shielding sheet 5 is required, reducing the number of shielding sheets 5 and lowering the cost of the connector 7.
[0129] In some embodiments, as shown in Figures 6-9, the shielding shell body 221 of the connector housing 6 has a insertion groove 2212 on the side away from the shielding sleeve 222. The insertion groove 2212 is suitable for inserting the shielding sheet 5. Specifically, the shielding shell body 221 includes a plurality of sidewalls arranged sequentially along a third direction X. The insertion groove 2212 is provided on the sidewall at the middle position. The shielding sheet 5 is provided with an assembly groove 50. The shielding sheet 5 is inserted into the insertion groove 2212 on the shielding shell body 221 along the second direction Y. The insertion groove 2212 and the assembly groove 50 are press-fitted together, thereby fixing the shielding sheet 5 inside the first shielding shell 21. The contact surface 51 of the shielding sheet 5 abuts against the second abutting surface 330 of the second conductive terminal 33, fixing the second conductive terminal 33 onto the shielding shell body 221. In addition, the first conductive terminal 32 can also be fixed inside the first shielding shell 21 by abutting against the first abutting surface 320 of the first conductive terminal 32 on the inner wall surface of the second shielding shell 22 along the first direction Z. In this way, the shielding plate 5, the first conductive terminal 32, and the second conductive terminal 33 can be more firmly fixed inside the connecting housing, improving the reliability and stability of the connector 7.
[0130] In some embodiments, the connector housing 6 includes a plastic housing 1, a first shielding housing 21, and a second shielding housing 22; the conductive terminal 3 passes through the second shielding housing 22 along the first direction Z, the plastic housing 1 is connected to the second shielding housing 22 along the first direction Z, and the first shielding housing 21 is sleeved on the outside of a portion of the plastic housing 1 and a portion of the second shielding housing 22 along the second direction Y.
[0131] Specifically, during assembly, the conductive terminal 3 is first inserted into the shielding shell body 221 and shielding sleeve 222 of the second shielding shell 22 along the first direction Z. The body portion 11 of the plastic shell 1 is sleeved on the outside of the shielding sleeve 222 along the first direction Z. The extension portion 10 of the plastic shell 1 is connected to the shielding shell body 221 along the first direction Z. The first shielding shell is sleeved on the outside of the extension portion 10 and the shielding shell body 221 along the second direction Y.
