Description

Technical Field

[0001] This invention belongs to the field of connector technology, and particularly relates to a board-end connector housing and a board-end connector. Background Technology

[0002] Board-end connectors are electrical connectors used to enable electrical conduction between circuit boards and cables or other electronic devices. The housing of a board-end connector includes a plastic housing and a shielding housing disposed within the plastic housing. The shielding housing covers the outside of the conductive terminals to prevent the influence of external electrostatic or electromagnetic induction on the internal current or signal.

[0003] Currently, some board-end connectors on the market have shielding shells composed of two shielding parts to improve the ease of assembly between the conductive terminals and the shielding shell. However, the assembly method of the two shielding parts is as follows: one shielding part is assembled inside the other, with the inner shielding part connected to the circuit board and the outer shielding part connected to the outer shell. This connection method results in insufficient connection strength between the two shielding parts, making them prone to detachment, thus leading to a shorter lifespan for the board-end connector. Furthermore, the electromagnetic induction between the conductive terminals of the connected circuit board protruding from the shielding shell can easily affect each other, resulting in poor shielding effectiveness.

[0004] Therefore, there is an urgent need for a board-end connector housing and a board-end connector to solve the above-mentioned technical problems. Summary of the Invention

[0040] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0041] like Figures 1 to 5 As shown, this embodiment provides a board-end connector, which includes a conductive terminal 10, an insulator 30, a circuit board 20, and a board-end connector housing. One end of the board-end connector housing along a first direction is provided with a mating interface 13 for insertion with a mating connector. A terminal mounting channel through which the conductive terminal 10 passes is provided inside the board-end connector housing. The insulator 30 is disposed inside the terminal mounting channel and sleeved on the conductive terminal 10. The circuit board 20 is connected to the board-end connector housing. One end of the conductive terminal 10 passes through the first channel opening 231 of the terminal mounting channel and is connected to the circuit board 20, and the other end extends to the second channel opening 232 of the terminal mounting channel. The end of the conductive terminal 10 located at the second channel opening 232 is used for electrical connection with the mating terminal of the mating connector.

[0042] Specifically, such as Figure 1 and Figure 2 As shown, the board-end connector housing provided in this embodiment includes a shielding housing 2. The shielding housing 2 has multiple terminal mounting channels. The two ends of the terminal mounting channels are a first channel opening 231 and a second channel opening 232, respectively. The terminal mounting channels are used to pass through conductive terminals 10. One end of the conductive terminal 10 extends into the second channel opening 232 for electrical connection to the mating terminal of the connector. The other end of the conductive terminal 10 passes through the first channel opening 231 and is electrically connected to the circuit board 20. The shielding housing 2 includes a first shielding shell 21 and a second shielding shell 22 assembled and connected to the first shielding shell 21. Figure 5 As shown, a first circuit board soldering part 217 is provided on the first shielding shell 21, and a second circuit board soldering part 224 is provided on the second shielding shell 22. The first circuit board soldering part 217 and the second circuit board soldering part 224 are connected to each other, and the first circuit board soldering part 217 and / or the second circuit board soldering part 224 are provided to block any two adjacent first channel openings 231.

[0043] The board-end connector housing provided in this embodiment includes a shielding housing 2 comprising a first shielding housing 21 and a second shielding housing 22. The first shielding housing 21 and the second shielding housing 22 are assembled and connected. The first circuit board welding portion 217 of the first shielding housing 21 and the second circuit board welding portion 224 of the second shielding housing 22 can be simultaneously welded to the circuit board 20, thereby improving the connection strength between the first shielding housing 21 and the second shielding housing 22. Moreover, the first circuit board welding portion 217 and / or the second circuit board welding portion 224 are provided to block any two adjacent first channel openings 231. The first circuit board welding portion 217 and the second circuit board welding portion 224 are welded to the circuit board 20 to form a closed barrier wall, which blocks the conductive terminals 10 passing through the two adjacent first channel openings 231, thereby improving the shielding effect between the conductive terminals 10.

[0044] Specifically, both the first shielding shell 21 and the second shielding shell 22 are provided with a plurality of circuit board connecting posts 215. The circuit board connecting posts 215 are inserted into the connecting holes 201 of the circuit board 20 one by one, so as to realize the simultaneous connection of the circuit board 20 and the first shielding shell 21 and the second shielding shell 22, further improving the connection strength between the first shielding shell 21 and the second shielding shell 22.

[0045] Specifically, the board-end connector housing also includes an outer shell 1. A shielding sleeve through hole 11 is provided on one side wall along the first direction, and a first opening is provided on the other end. A second opening is provided on one side of the outer shell 1 along the second direction. The first direction is perpendicular to the second direction. A first shielding shell 21 is assembled inside the outer shell 1 along the first direction. A second channel port 232 is provided at one end of the first shielding shell 21, and this end passes through the shielding sleeve through hole 11. A second shielding shell 22 is assembled inside the outer shell 1 along the second direction and is inserted into the other end of the first shielding shell 21 along the second direction. The first channel port 231, the first circuit board soldering part 217, and the second circuit board soldering part 224 are all exposed through the second opening. The first shielding shell 21 is assembled inside the outer shell 1 along the first direction, and one end of the first shielding shell 21 passes through the shielding sleeve through hole 11. Therefore, all movements of the first shielding shell 21 except for retraction in the first direction are constrained by the outer shell 1. The second shielding shell 22 is assembled inside the outer shell 1 along the second direction and is inserted into the other end of the first shielding shell 21 along the second direction. Therefore, the second shielding shell 22 restricts the retraction of the first shielding shell 21, that is, all movements of the first shielding shell 21 in any direction are constrained, improving the reliability of the first shielding shell 21's fixation. Moreover, the second shielding shell 22 is simultaneously inserted into both the first shielding shell 21 and the outer shell 1, resulting in higher fixation reliability for the second shielding shell 22. Therefore, the board-end connector housing proposed in this embodiment improves the assembly reliability of the shielding shell 2 and the outer shell 1.

[0046] Specifically, such as Figure 2 and Figure 3 As shown, the inner wall of the outer shell 1 is provided with a first insertion portion 12, the end of the first shielding shell 21 near the first opening is provided with a third insertion portion, and the second shielding shell 22 is provided with a second insertion portion 221 and a fourth insertion portion spaced apart from each other. The second insertion portion 221 is inserted into the first insertion portion 12 along a second direction, and the fourth insertion portion is inserted into the third insertion portion along the second direction. The cooperation between the second insertion portion 221 and the first insertion portion 12 realizes the cooperative insertion of the outer shell 1 and the second shielding shell 22. The cooperation of the fourth insertion portion into the third insertion portion along the second direction realizes the cooperative insertion of the first shielding shell 21 and the second shielding shell 22.

[0047] Specifically, such as Figure 1 and Figure 2 As shown, the third connector includes a slot 2111 extending along the second direction, and the fourth connector includes a plug 2221, which is inserted into the slot 2111. The mating of the plug 2221 and the slot 2111 enables the connection between the first shielding shell 21 and the second shielding shell 22.

[0048] More specifically, slot 2111 is a U-shaped recess, and plug 2221 is a U-shaped protrusion. The insertion of the U-shaped recess and the U-shaped protrusion makes the connection between the first shielding shell 21 and the second shielding shell 22 more secure.

[0049] Specifically, such as Figure 4 and Figure 5 As shown, the third insertion part further includes a first strip-shaped protrusion 2112 extending along the second direction, and the fourth insertion part further includes a first strip-shaped groove 2222 extending along the second direction. The first strip-shaped protrusion 2112 is inserted into the first strip-shaped groove 2222. The cooperation between the first strip-shaped protrusion 2112 and the first strip-shaped groove 2222 plays a limiting and guiding role for the second shielding shell 22.

[0050] More specifically, the first strip-shaped protrusion 2112 and the slot 2111 are distributed along the second direction, and the first strip-shaped groove 2222 and the plug 2221 are distributed along the second direction. This arrangement makes the structure of the third and fourth plug-in portions compact and occupies little space.

[0051] More specifically, the slot 2111 is located on the side of the first strip-shaped protrusion 2112 near the second opening, and the plug 2221 is located on the side of the first strip-shaped groove 2222 near the second opening. This arrangement ensures that when the second shielding shell 22 is assembled into the outer shell 1 along the second direction, the first strip-shaped protrusion 2112 and the first strip-shaped groove 2222 first engage to guide and limit the movement of the second shielding shell 22. Just as the second shielding shell 22 is about to be fully installed, the plug 2221 is inserted into the slot 2111 until it is fully inserted.

[0052] Specifically, such as Figure 2 As shown, the first insertion portion 12 includes a second strip-shaped groove 121 extending along the second direction, and the second insertion portion 221 includes a second strip-shaped protrusion 2211 extending along the second direction. The second strip-shaped protrusion 2211 is inserted into the second strip-shaped groove 121. The mating insertion of the second strip-shaped groove 121 and the second strip-shaped protrusion 2211 realizes the connection between the second shielding shell 22 and the outer shell 1.

[0053] Specifically, see [link to relevant documentation] Figure 2 The first insertion portion 12 includes at least two second strip-shaped grooves 121 arranged at intervals along a first direction. Correspondingly, the second insertion portion 221 includes at least two second strip-shaped protrusions 2211 arranged at intervals along the first direction. The second strip-shaped grooves 121 and the second strip-shaped protrusions 2211 are inserted into each other in a one-to-one correspondence. This further improves the connection strength between the second shielding shell 22 and the outer shell 1.

[0054] Specifically, such as Figure 1 and Figure 6 As shown, the first shielding shell 21 has an extension plate 214 extending toward the second shielding shell 22 on the side opposite to the first channel opening 231, and the second shielding shell 22 has a notch 223 on the side opposite to the first channel opening 231. The extension plate 214 is fitted into the notch 223. The fit between the notch 223 and the extension plate 214 improves the assembly accuracy and reliability of the first shielding shell 21 and the second shielding shell 22.

[0055] Specifically, such as Figure 4 and Figure 6 As shown, the third insertion portion further includes a third strip-shaped protrusion 2113 extending along the first direction, which is disposed on the extension plate 214. The fourth insertion portion further includes a third strip-shaped groove 2223 extending along the first direction, which is located within the notch 223, and the third strip-shaped protrusion 2113 is inserted into the third strip-shaped groove 2223. The cooperation between the third strip-shaped protrusion 2113 and the third strip-shaped groove 2223 further improves the assembly accuracy and assembly reliability of the first shielding shell 21 and the second shielding shell 22.

[0056] More specifically, the outer casing 1 has a first insertion portion 12 on each of its two opposing inner walls along a third direction, the third direction being perpendicular to the first and second directions. The second shielding shell 22 has a second insertion portion 221 on each of its two opposing outer walls along the third direction. The first insertion portions 12 and the second insertion portions 221 are inserted into each other in a one-to-one correspondence. That is, both sides of the second shielding shell 22 are connected to the outer casing 1, which improves the connection strength between the second shielding shell 22 and the outer casing 1.

[0057] Specifically, such as Figure 2 and Figure 4As shown, multiple shielding sleeve perforations 11 are spaced apart from each other. The first shielding shell 21 includes a shielding block 212 and multiple shielding sleeves 213. The shielding block 212 is disposed inside the outer shell 1. One end of each of the multiple shielding sleeves 213 is inserted through the shielding sleeve perforation 11, and the opening at that end is a second channel port 232. The other end of each of the multiple shielding sleeves 213 is connected to the shielding block 212. The shielding block 212 has several grooves 2121 on the side away from the shielding sleeves 213. A number of shielding sleeves 213 are connected to several grooves 2121. The several grooves 2121 and the second shielding shell 22 form several first channel ports 231. The second shielding shell 22 has several first channel ports 231 that are connected to the remaining number of shielding sleeves 213. This arrangement further improves the ease of assembly between the conductive terminal 10 and the shielding shell 2. Furthermore, both the first shielding shell 21 and the second shielding shell 22 are partially exposed through the second opening, ensuring that the circuit board 20 is connected to both the first shielding shell 21 and the second shielding shell 22, which helps to improve the fixing strength of the circuit board 20. In this embodiment, the circuit board 20 is simultaneously soldered to both the first shielding shell 21 and the second shielding shell 22.

[0058] Specifically, in this embodiment, the first shielding shell 21 is provided with two grooves 2121 spaced apart along a third direction. The two grooves 2121 and the second shielding shell 22 form two first channel openings 231 spaced apart along a third direction. The second shielding shell 22 is provided with two first channel openings 231 spaced apart along a third direction. The four first channel openings 231 are arranged in two rows and two columns, forming a configuration as shown in the figure. Figure 1 The grid-shaped structure shown has a circuit board connecting post 215 at each of its four corners, ensuring a reliable connection between the shielding shell 2 and the circuit board 20. Correspondingly, as... Figure 4 As shown, four shielding sleeves 213 are provided. Two shielding sleeves 213 near the second opening are respectively connected to two grooves 2121. The other two shielding sleeves 213 are respectively connected to one end of two through slots on the shielding block 212. The other ends of the two through slots are respectively connected to two connecting ports of the second shielding shell 22. The two connecting ports are respectively connected to two first channel ports 231 on the second shielding shell 22.

[0059] More specifically, in this embodiment, the first circuit board soldering part 217 and the second circuit board soldering part 224 are connected to form a cross-shaped structure. The four ends of the cross-shaped structure are respectively disposed between the four first channel openings 231, blocking the conductive terminals 10 passing through the four first channel openings 231, thereby improving the shielding effect between the conductive terminals 10.

[0060] Specifically, both the first shielding shell 21 and the second shielding shell 22 are provided with a plurality of circuit board connecting posts 215, which extend outward through a second opening. The circuit board connecting posts 215 are inserted into the connecting holes 201 of the circuit board 20, thereby achieving simultaneous connection of the circuit board 20 and the first shielding shell 21 and the second shielding shell 22. Moreover, since the movement of the first shielding shell 21 in any direction is constrained, the movement of the second shielding shell 22, except for the retraction in the second direction, is constrained by the outer shell 1 and the first shielding shell 21. Furthermore, since the circuit board 20 is connected to both the first shielding shell 21 and the second shielding shell 22, the movement of the second shielding shell 22 in the retraction direction is constrained by the circuit board 20. This further restricts the movement of the second shielding shell 22 in any direction, thus improving the stability of the second shielding shell 22.

[0061] Specifically, such as Figure 4 As shown, the inner wall of the outer shell 1 has an abutment surface 14 facing the second opening. The side walls of the first shielding shell 21 and the second shielding shell 22 are provided with abutment protrusions 216 near the second opening. The abutment protrusions 216 abut against the abutment surface 14, which improves the reliability of fixing the first shielding shell 21 and the second shielding shell 22.

[0062] More specifically, one end of the second strip groove 121 extends to the abutment surface 14, and the other end extends toward the side away from the second opening. One end of the second strip protrusion 2211 is connected to the abutment boss 216, and the other end extends toward the side away from the second opening. With this configuration, after the first shielding shell 21 and the second shielding shell 22 are assembled inside the outer shell 1, the abutment boss 216 covers the second strip protrusion 2211 and the second strip groove 121, which not only improves the reliability of the connection between the shielding shell 2 and the outer shell 1, but also widens the connection area between the first shielding shell 21 and the second shielding shell 22 and the circuit board 20.

[0063] Specifically, in this embodiment, the first insertion portion 12 includes two second strip-shaped grooves 121, one of which is longer than the other. The second insertion portion 221 includes two second strip-shaped protrusions 2211, one of which is longer than the other. The longer second strip-shaped protrusion 2211 and the longer second strip-shaped groove 121 fit loosely together for limiting and guiding, while the shorter second strip-shaped protrusion 2211 and the shorter second strip-shaped groove 121 fit tightly together to ensure connection strength.

[0064] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
