[0036] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0037] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0038] In the description of this invention, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0039] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0040] like Figures 1 to 11 As shown, this embodiment provides an electrical connector, including a housing 3 and a first connecting component 1 disposed on the housing 3. The housing 3 is provided with a first opening 31 and a second opening 32.

[0041] The first connecting assembly 1 includes a first insulator 15, a retaining buckle 16, and a terminal. The first insulator 15 is provided with a mounting base 151, a mounting hole 152, and a socket 153 sequentially along a first direction. The socket 153 is exposed to the outside through a first opening 31. The retaining buckle 16 is disposed on the mounting base 151 and has a through hole 161 along a second direction, which communicates with the second opening 32. The first and second directions are arranged at an angle. The mounting base 151 and the retaining buckle 16 are positioned by a positioning structure and are detachably connected. The terminal includes a main body 1A and a bent portion 1B. The main body 1A passes through the mounting hole 152 and between the retaining buckle 16 and the mounting base 151, with one end extending into the socket 153 and the other end connected to the bent portion 1B. The bent portion 1B passes through the through hole 161, and the main body 1A and the mounting hole 152 are interference-fitted.

[0042] The terminal and the first insulator 15 are assembled. The main body 1A passes through and is interference-fitted into the mounting hole 152, with one end extending into the socket 153 and the other end connected to the bent portion 1B and located at the mounting base 151. Then, the retaining clip 16 is connected to the mounting base 151, while the other end of the main body 1A is sandwiched between the retaining clip 16 and the mounting base 151. The bent portion 1B passes through the through hole 161. Since the socket 153 is exposed to the outside through the first opening 31, one end of the main body 1A is exposed to the outside through the socket 153 and the first opening 31. Since the through hole 161 and the second opening 32 are connected, the bent portion 1B passes through the through hole 161 and is exposed through the second opening 32, thereby realizing the terminal's function for electrical connection.

[0043] By separating the first insulator 15, the terminal, and the retaining clip 16, the main body 1A of the terminal is fixedly installed to the first insulator 15, the bent part 1B is fixedly installed to the retaining clip 16, and the retaining clip 16 and the first insulator 15 are fixedly installed separately, thus achieving fixed installation of the terminal on the first insulator 15 and the retaining clip 16. The retaining clip 16 and the main body 1A are positioned by a positioning structure before being connected, ensuring the installation accuracy of the retaining clip 16 and the main body 1A, thereby ensuring the relative positional accuracy of the through hole 161 and the mounting hole 152, and thus ensuring the installation accuracy of the terminal. The terminal and the first insulator 15 are interference-fitted, and the through hole 161 of the retaining clip 16 further limits the terminal, ensuring that the terminal does not fall off or move arbitrarily in the first insulator 15 and the retaining clip 16. Therefore, compared with the secondary molding process, the assembly process of the electrical connector improves the positioning accuracy of the terminal, thereby solving the problem of poor mating between the electrical connector and the mating connector.

[0044] The angle between the second direction and the first direction can be 90°, 120°, or 150°, etc. The through hole 161 is provided along the second direction, and the mounting hole 152 is provided along the first direction. That is, the main body 1A installed in the mounting hole 152 extends along the first direction, and the bent part 1B passing through the through hole 161 extends along the second direction. The main body 1A and the bent part 1B form an angle of 90°, 120°, or 150°, etc.

[0045] The electrical connector includes four or more terminals. In one embodiment, the electrical connector includes six terminals: two first terminals 13 arranged along a third direction, two second terminals 14 arranged along a third direction, and two third terminals 17 arranged along a third direction. The main body portions 1A corresponding to the first terminals 13, third terminals 17, and second terminals 14 are arranged sequentially along a second direction, and the corresponding bent portions 1B are arranged sequentially along a first direction, all extending in the same direction. The first terminals 13 are located inside the third terminals 17, and the third terminals 17 are located inside the second terminals 14. The first terminals 13, second terminals 14, and third terminals 17 do not intersect each other. When more terminals are provided, they can be arranged along the second direction or along a third direction.

[0046] In one embodiment, the first terminal 13 and the second terminal 14 are used as examples for illustrative description. One end of the main body 1A of the first terminal 13 is provided with a connecting portion 1C that connects to the bending portion 1B. Along the direction from the main body 1A to the bending portion 1B, the connecting portion 1C is inclined toward the main body 1A of the second terminal 14, so that the bending portion 1B of the first terminal 13 is close to the main body 1A of the second terminal 14, and the distance between the other end of the bending portion 1B and the second terminal 14 is reduced. This enables the thinning design of the fixing buckle 16 along the second direction, thereby enabling the miniaturization design of the electrical connector.

[0047] Optionally, the end of the main body 1A is also provided with a connecting part 1F, which connects the bent part 1B and the connecting part 1C. The connecting part 1F passes through the mounting base 151 and the fixing buckle 16. The connecting part 1F is flat and parallel to the mounting base 151 and the fixing buckle 16 respectively. The mounting base 151 and the fixing buckle 16 further limit the connecting part 1F.

[0048] The positioning structure includes a positioning post 162 and a positioning seat 154 that fit together through an interlocking mechanism. One of the mounting base 151 and the fixing buckle 16 has a positioning post 162, and the other has a positioning seat 154. The positioning seat 154 can be a positioning groove or positioning hole that matches the shape and size of the positioning post 162. In one embodiment, the positioning post 162 is located on the fixing buckle 16, and the positioning seat 154 is located on the mounting base 151. The positioning post 162 and the positioning seat 154 are interlocked, thereby achieving the positioning of the mounting base 151 and the fixing buckle 16.

[0049] The positioning seat 154 is a positioning groove, which is provided on one side of the main body 1A along the second direction. For example, the positioning groove is located on one side of the main body 1A of the second terminal 14. The positioning structure does not occupy space in the first and second directions, thereby reducing the size of the electrical connector. By setting the positioning seat 154 as a positioning groove, the positioning post 162 is prevented from contacting the terminal.

[0050] The device has two terminals. For example, the two terminals are a first terminal 13 and a second terminal 14. The main body 1A of the two terminals is arranged along a second direction, and the bent portion 1B of the two terminals is arranged along a first direction. The positioning seat 154 is disposed between the corresponding bent portions 1B of the two terminals along the first direction. By utilizing the installation space between the two bent portions 1B, the volume of the electrical connector can be effectively reduced.

[0051] The positioning structure is located on the side of the terminal along a third direction, which is set at an angle to the first and second directions respectively. For example, the terminal is a third terminal 17, and the two sets of positioning posts 162 and positioning seats 154 of the positioning structure are located on both sides of the two third terminals 17. Since the width of the third terminal 17 is relatively narrow, the space on both sides of the third terminal 17 can be fully utilized, thereby reducing the size of the electrical connector.

[0052] The retaining buckle 16 and the mounting base 151 are engaged. For example, the mounting base 151 has a retaining seat 155, and the retaining buckle 16 has a retaining buckle 163. The retaining buckle 163 and the retaining seat 155 are engaged, thereby achieving a detachable connection between the mounting base 151 and the retaining buckle 16. The mounting base 151 has a mounting groove 156, the retaining buckle 16 is disposed within the mounting groove 156, a positioning post 162 is disposed on the back of the retaining buckle 16, and a positioning seat 154 is disposed within the mounting groove 156. Mounting base 151 has a snap-fit ​​seat 155 on the side opposite to the opening of mounting groove 156. Mounting base 151 is installed into mounting groove 156, and positioning pin 162 and positioning seat 154 are positioned and installed simultaneously. After fixing buckle 16 is installed in place, snap-fit ​​buckle 163 and snap-fit ​​seat 155 are snapped and fixed. Through the above settings, fixing buckle 16 and mounting base 151 are installed along the second direction, realizing that mounting base 151 and fixing buckle 16 are first positioned and then snapped and installed, and the action is continuous.

[0053] The main body 1A is provided with a locking point 1D, which is a protruding point that protrudes outward. The locking point 1D is interference-fitted with the wall of the mounting hole 152, and the locking point 1D has a large holding force to ensure that the main body 1A is stably installed in the mounting hole 152.

[0054] The main body 1A has a limiting flange 1E on its side. The limiting flange 1E is positioned between the first insulator 15 and the fixing buckle 16 along the first direction, thereby limiting the limiting flange 1E, i.e., the terminal, along the first direction, further improving its installation stability and preventing it from falling off. For example, the main body 1A has limiting flanges 1E on both sides along the third direction, further improving its installation stability.

[0055] The electrical connector also includes a second connecting component 2, which can pass through the second opening 32 for mounting on the housing 3 and is electrically connected to the bend 1B. The second connecting component 2 is used to connect to a cable 28, which is located outside the housing 3, with one end of the cable 28 electrically connected to the bend 1B. The second connecting component 2 and the first connecting component 1 are separate components. The housing 3 and the first connecting component 1 are connected first, and after the housing 3 is installed on the external device, the second connecting component 2 with the cable 28 is then assembled, which facilitates assembly and maintenance.

[0056] In one embodiment, the fixing buckle 16 has a first insertion slot 11 and a second insertion slot 12, the first terminal 13 (i.e., the bent portion 1B) extends into the first insertion slot 11, and the second terminal 14 (i.e., the bent portion 1B) extends into the second insertion slot 12.

[0057] The second connecting assembly 2 includes a second insulator 26 and conductive mounting heads 27 mounted on the second insulator 26. The second insulator 26 is provided with a first connector 21 and a second connector 22. One end of each conductive mounting head 27 forms a first socket 23 and a second socket 24, respectively. The other end of the conductive mounting head 27 is used to connect to a cable 28. After the second connecting assembly 2 passes through the second opening 32, the first connector 21 is inserted into the first socket 11, and the second connector 22 is inserted into the second socket 12 to achieve a mechanical connection. The first terminal 13 is inserted into the first socket 23, and the second terminal 14 is inserted into the second socket 24 to achieve an electrical connection.

[0058] Optionally, the first and second insertion slots 11 and 12 are stepped, as are the first and second connectors 21 and 22. During insertion, the second insertion slot 12 and the second connector 22 are inserted first, while the second terminal 14 and the second socket 24 are inserted simultaneously. Then, the first insertion slot 11 and the first connector 21 are inserted, while the first terminal 13 and the first socket 23 are inserted, thus achieving a foolproof design. Alternatively, some connectors and insertion slots (the second connector 22 and the second insertion slot 12), terminals and sockets (the second terminal 14 and the second socket 24) can be inserted first, while other connectors and insertion slots (the first connector 21 and the first insertion slot 11), terminals and sockets (the first terminal 13 and the first socket 23) are inserted later. This reduces insertion and extraction force, facilitates operation, and avoids damage to the electrical connector due to excessive insertion and extraction force.

[0059] The second insulator 26 has a buckle 25 on its side and a slot 33 on the inside of the housing 3. The buckle 25 is engaged with the slot 33, thereby enabling the second insulator 26 to be engaged in the housing 3. This ensures that the second insulator 26, i.e. the second connecting component 2, is stably installed with the housing 3, thereby ensuring the stable installation of the second connecting component 2 with the first connecting component 1, as well as the stable connection of the first terminal 13 and the first socket 23, the second terminal 14 and the second socket 24, and thus ensuring the reliability of the electrical connection.

[0060] The end of the second insulator 26 is provided with a limiting stop 261, which can limit the end of the housing 3 at the second opening 32. During the insertion process of the second connecting component 2 and the first connecting component 1, the limiting stop 261 and the housing 3 limit each other to prevent the first connecting component 1 and the second connecting component 2 from being over-inserted.

[0061] The second connecting component 2 is sealed to the housing 3 through the sealing ring 5, thereby achieving internal sealing of the housing 3.

[0062] The housing 3 has a connection hole 34 for connecting to external equipment. Optionally, a mounting platform protrudes from the outer side of the housing 3, and the mounting platform has a connecting ring 36. The connecting ring 36 forms the connection hole 34. Screws pass through the connecting ring 36 for connecting to external equipment. By setting the connecting ring 36, which is like a metal ring, its structural strength is high, and it can prevent damage during the direct connection of the housing 3 with fasteners such as screws. The first connecting component 1 is installed with the housing 3, and the housing 3 is fixed to the external equipment by screws. Then, the second connecting component 2 with cable 28 is installed into the housing 3 and plugged into the first connecting component 1. Finally, the electrical connector is plugged into the socket 153 of the first connecting component 1 and electrically connected to the main body 1A inside the socket 153.

[0063] The electrical connector also includes a first shield 41 and a second shield 42 disposed within the housing 3 and interconnected. The first shield 41 covers the first connecting assembly 1, and the second shield 42 covers the second connecting assembly 2. The first shield 41 passes through a first opening 31 to be disposed within the housing 3, and the first shield 41 is detachably connected to the housing 3 and the first connecting assembly 1. The second shield 42 passes through a second opening 32 to be disposed within the housing 3, and the second shield 42 is detachably connected to the housing 3 and the second connecting assembly 2.

[0064] The first shielding cover 41 has an installation port 411 on the side facing the second shielding cover 42. The second shielding cover 42 is installed into the installation port 411. The installation port 411 and the second shielding cover 42 are connected around their perimeter to form a contact point 4C, so that the first shielding cover 41 and the second shielding cover 42 completely cover the first connecting component 1 and the second connecting component 2, resulting in a good shielding effect.

[0065] The first shield 41 has an opening at one end, and a hook 412 is provided at the opening. The first connecting component 1 passes through the opening and is installed inside the first shield 41. It is connected to the first insulator 15 through the hook 412. After that, the first connecting component 1 and the first shield 41 are assembled together and then pass through the first opening 31 and installed into the housing 3.

[0066] The second shield 42 is provided with a folded edge 421, which can abut against the outer edge of the housing 3. The second shield 42 is first installed into the housing 3 so that the second shield 42 is connected to the first shield 41. Then the second connecting component 2 is installed into the second shield 42 and connected to the first connecting component 1.

[0067] Both the first shielding cover 41 and the second shielding cover 42 are provided with a locking protrusion 4D, and the inner side of the housing 3 is provided with a limiting groove 35. The locking protrusion 4D and the limiting groove 35 are connected to realize that the first shielding cover 41 and the second shielding cover 42 are respectively limited and connected to the housing 3.

[0068] Both the first shielding cover 41 and the second shielding cover 42 are provided with a first spring piece 4A. The first spring piece 4A and the inner wall of the housing 3 elastically abut against each other, so that the first shielding cover 41 and the second shielding cover 42 are elastically connected to the housing 3 respectively.

[0069] Both the first shielding cover 41 and the second shielding cover 42 are provided with second spring pieces 4B. The first shielding cover 41 elastically abuts against the first connecting component 1, i.e., the first insulator 15, through the second spring pieces 4B, thereby achieving an elastic connection between the first insulator 15 and the first shielding cover 41. The second shielding cover 42 elastically abuts against the second connecting component 2, i.e., the second insulator 26, through the second spring pieces 4B, thereby achieving an elastic connection between the second insulator 26 and the second shielding cover 42.

[0070] The second shield 42 is provided with a clearance opening, and the buckle 25 on the side of the second insulator 26 passes through the clearance opening to engage with the slot 33 on the housing 3.

[0071] This embodiment also provides an electrical connector assembly, including an electrical connector and a mating electrical connector, wherein the socket 153 of the electrical connector and the plug of the mating electrical connector are inserted into each other, and the main body 1A of the electrical connector is electrically connected to the mating electrical connector.

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.
