Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and in particular to an electrical connector and an electrical connector assembly. Background Technology

[0002] With the trend towards integration and miniaturization of electronic devices, multi-core electrical connectors are widely used in industrial automation equipment, automotive electronic systems, medical instruments, and consumer electronics products because they can transmit multiple signals or power simultaneously. Multi-core connectors typically contain a large number of contact pairs, and each contact pair needs to achieve a reliable electrical connection through contact during mating to ensure the stability of signal transmission and the continuity of power supply.

[0003] To ensure reliable contact, each contact pair requires a certain positive contact force. However, as the number of contact pairs increases, the positive contact forces of each pair are superimposed, leading to a significant increase in the overall insertion and extraction force of the electrical connector. Excessive insertion and extraction force, on the one hand, increases the difficulty of manual insertion and extraction operations; on the other hand, it may damage the connector's structure, affecting the contact stability of the contact pairs and causing malfunctions such as poor contact. Utility Model Content

[0004] This utility model provides an electrical connector and an electrical connector assembly that reduces insertion and extraction force, thereby reducing the difficulty of insertion and extraction operations and avoiding damage to the electrical connector caused by excessive insertion and extraction force.

[0006] The first connecting component includes a first insertion slot, a second insertion slot, a first terminal passing through the first insertion slot, and a second terminal passing through the second insertion slot; the depth of the first insertion slot is greater than the depth of the second insertion slot.

[0007] The second connection component includes a first connector, a second connector, a first socket in the first connector, and a second socket in the second connector. The first socket and the second socket are used to connect two cables respectively. The first connector is inserted into the first connector slot, and one end of the first terminal is inserted into the first socket to be electrically connected to the corresponding cable. One end of the second connector is inserted into the second connector slot, and the second terminal is inserted into the second socket to be electrically connected to the corresponding cable. The first connector and the second connector are stepped, and the height of the first connector is greater than the height of the second connector.

[0008] In some embodiments, the entrance of the first socket and the entrance of the second socket are located on the same plane.

[0009] In some embodiments, a housing is further included, the housing having a first opening and a second opening, the second connecting component being able to pass through the housing through the second opening and be inserted into the first connecting component inside the housing, the other ends of the first terminal and the second terminal being exposed through the first opening, and the cable corresponding to the first socket and the second socket being able to pass through the second opening.

[0010] In some embodiments, the second connecting component snaps onto the inner wall of the housing.

[0011] In some embodiments, the device further includes a first shield and a second shield disposed within the housing and connected to each other. The first shield covers the first connecting assembly, and the second shield covers the second connecting assembly. The second connecting assembly is detachably connected to the second shield.

[0012] In some embodiments, the second shield passes through the second opening and is detachably connected to the housing.

[0013] In some embodiments, both the first terminal and the second terminal include a main body portion and a bent portion disposed at an angle, the main body portions of both the first terminal and the second terminal extend along a first direction, and the bent portions of both the first terminal and the second terminal extend along a second direction; the second connecting component is inserted into the first connecting component along the second direction.

[0014] In some embodiments, the first connection assembly includes a first insulator and a retaining buckle. The retaining buckle is mounted on the first insulator along the second direction. The retaining buckle is provided with a first insertion slot and a second insertion slot. The main body is interference-fitted to the first insulator.

[0015] In some embodiments, the main body portion of the first terminal further includes a connecting portion connected to the bending portion, and the connecting portion is inclined toward the second terminal along the direction of the main body portion toward the bending portion.

[0016] An electrical connector assembly includes an electrical connector as described in any of the preceding claims and a mating electrical connector, the electrical connector and the mating electrical connector being capable of mating connection.

[0017] The beneficial effects of this utility model embodiment:

[0018] By employing a stepped design for the first and second connectors, when the first and second connecting components are inserted, the second connector and the second slot are inserted first, while the second terminal and the second socket are simultaneously inserted. Then, the first connector and the first slot are inserted, while the first terminal and the first socket are simultaneously inserted. Reverse insertion is impossible, thus achieving a foolproof design. By inserting some connectors and slots, terminals and sockets first, and others later, compared to inserting all connectors and slots, terminals and sockets simultaneously, this step-by-step insertion avoids peak insertion force collisions, reduces the insertion and extraction forces between the first and second connecting components, simplifies the insertion and extraction process, and prevents damage to the electrical connector due to excessive insertion and extraction forces.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0037] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

"Below," "below," and "under" the second feature includes the first feature 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 this utility model 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 first connecting component 1 and a second connecting component 2. The first connecting component 1 includes a first insertion slot 11, a second insertion slot 12, a first terminal 13 passing through the first insertion slot 11, and a second terminal 14 passing through the second insertion slot 12. The second connecting component 2 includes a first connector 21, a second connector 22, a first socket 23 provided in the first connector 21, and a second socket 24 provided in the second connector 22. The first socket 23 and the second socket 24 are used to connect two cables 28 respectively. The first connector 21 is inserted into the first insertion slot 11, one end of the first terminal 13 is inserted into the first socket 23 for electrical connection with the corresponding cable 28, one end of the second connector 22 is inserted into the second insertion slot 12, and the second terminal 14 is inserted into the second socket 24 for electrical connection with the corresponding cable 28.

[0041] The first connector 21 is inserted into the first connector slot 11, and the second connector 22 is inserted into the second connector slot 12, thereby realizing the mechanical structural connection between the first connecting component 1 and the second connecting component 2. The first terminal 13 is inserted into the first socket 23, and the second terminal 14 is inserted into the second socket 24, thereby realizing the electrical connection between the first connecting component 1 and the second connecting component 2. Thus, the first terminal 13 is electrically connected to the corresponding cable 28 through the first socket 23, and the second terminal 14 is electrically connected to the corresponding cable 28 through the second socket 24.

[0042] The depth of the first socket 11 is greater than the depth of the second socket 12. The first connector 21 and the second connector 22 are stepped, and the height of the first connector 21 is greater than the height of the second connector 22.

[0043] Due to the stepped design of the first connector 21 and the second connector 22, when the first connecting component 1 and the second connecting component 2 are connected, the second connector slot 12 and the second connector 22 are connected first, and the second terminal 14 and the second socket 24 are connected at the same time; then the first connector slot 11 and the first connector 21 are connected, and the first terminal 13 and the first socket 23 are connected at the same time. They cannot be connected in reverse, thus achieving a foolproof design.

[0044] Some connectors and slots (second connector 22 and second slot 12), terminals and sockets (second terminal 14 and second socket 24) are inserted first with a first insertion force. The remaining connectors and slots (first connector 21 and first slot 11), terminals and sockets (first terminal 13 and first socket 23) are then inserted with a second insertion force. Compared to inserting all connectors and slots, terminals and sockets simultaneously with a third insertion force, both the first and second insertion forces are less than the third insertion force. By performing the insertion in stages, peak insertion force collisions are avoided, reducing the insertion and extraction forces between the first connecting component 1 and the second connecting component 2, facilitating operation, and preventing damage to the electrical connector due to excessive insertion and extraction forces.

[0045] The entrances of the first insertion slot 11 and the second insertion slot 12 are located on the same plane. Using this plane as a reference plane facilitates the design of the first insertion slot 11, the second insertion slot 12, the first connector 21, and the second connector 22. Furthermore, the bottom of the first insertion slot 11 and the bottom of the second insertion slot 12 are stepped, and the height difference between the first insertion slot 11 and the second insertion slot 12 is equal to the height difference between the first connector 21 and the second connector 22.

[0046] Both the first terminal 13 and the second terminal 14 include a main body portion 1A and a bent portion 1B arranged at an angle. The main body portion 1A of both the first terminal 13 and the second terminal 14 extends along a first direction, and the bent portion 1B of both the first terminal 13 and the second terminal 14 extends along a second direction. The second connecting component 2 is inserted into the first connecting component 1 along the second direction. The second direction and the first direction are arranged at an angle, which can be 90°, 120°, or 150°, etc. That is, the main body portion 1A and the bent portion 1B form an angle of 90°, 120°, or 150°, etc., realizing the bending setting of the electrical connector.

[0047] 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.

[0048] The electrical connector also includes a housing 3, which has a first opening 31 and a second opening 32. The second connecting component 2 can pass through the second opening 32 through the housing 3 and be inserted into the first connecting component 1 inside the housing 3. The other ends of the first terminal 13 and the second terminal 14 are exposed through the first opening 31, and the cable 28 corresponding to the first socket 23 and the second socket 24 can pass through the second opening 32. Specifically, the first connecting component 1 passes through the first opening 31 and is installed on the housing 3. One end of the first terminal 13 and the second terminal 14 is exposed in the first opening 31 for connection with the mating electrical connector, while the other end, as well as the first insertion slot 11 and the second insertion slot 12, are located inside the housing 3. The housing 3, the second connecting component 2, and the first connecting component 1 are separately arranged. During installation, the housing 3 and the first connecting component 1 are connected first. 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.

[0049] 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.

[0050] The first connecting assembly 1 includes a first insulator 15 and a retaining buckle 16. The retaining buckle 16 is mounted on the first insulator 15 along a second direction. The retaining buckle 16 has a first insertion groove 11 and a second insertion groove 12. The main body 1A is interference-fitted onto the first insulator 15. The bent portions 1B of the first terminal 13 and the second terminal 14 extend into the first insertion groove 11 and the second insertion groove 12 respectively. By setting separate first insulator 15, retaining buckle 16, first terminal 13 and second terminal 14, the terminals are assembled onto the first insulator 15 and retaining buckle 16. The interference fit of the main body 1A onto the first insulator 15 improves the installation accuracy of the terminals and the first insulator 15. Specifically, the retaining buckle 16 has through holes 161 at the bottom of the first insertion groove 11 and the second insertion groove 12. The terminals pass through the through holes 161 to extend into the corresponding insertion grooves. The through holes 161 further restrict the bent portions 1B to prevent the terminals from loosening.

[0051] The first insulator 15 is provided with a mounting base 151, a mounting hole 152, and a socket 153 in sequence along a first direction. The socket 153 is exposed to the outside through a first opening 31. A fixing buckle 16 is provided on the mounting base 151. The fixing buckle 16 is provided with a through hole 161 along a second direction. The through hole 161 communicates with the second opening 32. The first direction and the second direction are arranged at an angle. The mounting base 151 and the fixing buckle 16 are positioned by a positioning structure. The mounting base 151 and the fixing buckle 16 are detachably connected. The main body 1A passes through the mounting hole 152 and between the fixing buckle 16 and the mounting base 151. One end extends into the socket 153, and the other end is connected to the bent part 1B. The bent part 1B passes through the through hole 161. The main body 1A and the mounting hole 152 are interference-fitted.

[0052] The main body 1A of the first terminal 13 also includes a connecting part 1C connected to the bending part 1B. Along the direction from the main body 1A to the bending part 1B, the connecting part 1C is inclined toward the second terminal 14, so that the bending part 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 part 1B and the second terminal 14 is reduced. This enables the thinning design of the retaining buckle 16 along the second direction, thereby saving the material used to make the retaining buckle 16, reducing costs, and realizing the miniaturization design of the electrical connector.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] The two terminals are the first terminal 13 and the second terminal 14. The main body 1A of the two terminals is arranged along the second direction, and the bent portion 1B of the two terminals is arranged along the first direction. The positioning seat 154 is disposed between the corresponding bent portions 1B of the two terminals along the first direction, thereby utilizing the installation space between the two bent portions 1B to effectively reduce the size of the electrical connector.

[0059] 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.

[0060] 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.

[0061] The second connection 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 the two conductive mounting heads 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 the cable 28.

[0062] The second connecting component 2 is snapped into the inner wall of the housing 3. Specifically, the side of the second insulator 26 is provided with a buckle 25, and the inner side of the housing 3 is provided with a slot 33. The buckle 25 is snapped into the slot 33, thereby realizing the second insulator 26 being snapped into the housing 3, so that the second insulator 26, i.e. the second connecting component 2, is stably installed with the housing 3, ensuring the stable installation with the first connecting component 1, as well as the stable connection between the first terminal 13 and the first socket 23, the second terminal 14 and the second socket 24, thereby ensuring the reliability of the electrical connection.

[0063] 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.

[0064] The second connecting component 2 is sealed to the housing 3 through the sealing ring 5, thereby achieving internal sealing of the housing 3.

[0065] The electrical connector also includes a first shield 41 and a second shield 42 disposed within the housing 3 and connected to each other. The first shield 41 covers the first connecting component 1; the second shield 42 covers the second connecting component 2, and the second connecting component 2 is detachably connected to the second shield 42.

[0066] A first shielding cover 41 passes through a first opening 31 and is disposed within the housing 3. The first shielding cover 41 is detachably connected to the housing 3 and the first connecting assembly 1. A second shielding cover 42 passes through a second opening 32 and is disposed within the housing 3 and the second connecting assembly 2.

[0067] 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.

[0068] 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.

[0069] 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, and then the second connecting component 2 is installed into the second shield 42 and connected to the first connecting component 1.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] This embodiment also provides an electrical connector assembly, including the electrical connector as described above and a mating electrical connector, which are capable of being paired and connected.
