Description

Technical Field

[0001] This application relates to the field of electrical connector technology, and in particular to male connectors and electrical connectors. Background Technology

[0002] Electrical connectors, also known as circuit connectors or electronic connectors, are used to bridge two electrical components in a circuit, allowing current or signals to flow from one component to another. Because electrical connectors are easy to manufacture into standardized components and offer high electrical connection reliability, they are particularly suitable for modular components.

[0003] Electrical connectors typically consist of a male and a female connector that are connected to each other. The male connector includes a housing, terminals, and a terminal fixing structure. In the prior art, the terminal fixing structure is usually made separately from the housing. During the packaging process, the terminal fixing structure and the housing are packaged separately. Therefore, during the assembly process, the user needs to align the terminal fixing structure with the housing before assembling, which reduces assembly efficiency. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model proposes a male electrical connector, aiming to solve the technical problem of low assembly efficiency of traditional male electrical connectors at the user end.

[0005] To achieve the above objectives, the male connector proposed in this utility model includes:

[0006] The housing is provided with a limiting part, and the housing has an interconnected mounting port and a mounting cavity;

[0007] A terminal assembly is inserted into the mounting cavity through the mounting port, and the terminal assembly is provided with a stop member; and

[0008] A terminal locking element is movably connected to the housing;

[0009] The terminal locking member includes a limiting engagement part and a locking part connected to each other. The limiting engagement part includes an upper limit block and a lower limit block that are spaced apart along a first direction. The upper limit block, the lower limit block and the limiting part all extend along a second direction, and the first direction is perpendicular to the second direction.

[0010] The terminal locking member has a pre-pressed position and a locking position. In the pre-pressed position, the upper limit block and the lower limit block clamp the limiting part so that the locking part and the stop member are spaced apart.

[0011] In the locked position, the upper limit block is located on the side of the limiting portion near the terminal assembly, so that when the terminal locking member is pressed along the first direction, the upper limit block squeezes and expands the limiting portion, causing the locking portion to extend into the mounting cavity, and causing the locking portion to abut against the stop member to restrict the terminal assembly from exiting the mounting port.

[0012] In one embodiment, the terminal locking member further includes a body portion, the upper limit block and the lower limit block protruding from the side wall of the body portion, and the locking portion protruding from the bottom wall of the body portion near the terminal assembly;

[0013] The mounting cavity is provided with a boss, and the side wall of the body extends toward the terminal assembly to form a positioning part. In the locked position, the positioning part abuts against the boss to restrict the terminal locking member from pressing against the terminal assembly in the first direction.

[0014] In one embodiment, the limiting portion has a first guide slope away from the wall surface of the terminal assembly. The first guide slope is inclined from the outer wall surface of the housing toward the terminal assembly and toward the outer side of the housing.

[0015] Both the upper limit block and the lower limit block have a second guide slope that cooperates with the first guide slope on the wall surface near the terminal assembly.

[0016] In one embodiment, the terminal locking member has a lifting groove on the side away from the terminal assembly, and the groove wall of the lifting groove is used to be lifted to switch the terminal locking member from the locking position to the pre-pressed position.

[0017] In one embodiment, the limiting portion has a third guide slope near the wall surface of the terminal assembly, the third guide slope is inclined from the inside of the housing to the outside and toward the terminal assembly;

[0018] The lower limit block has a fourth guide slope that cooperates with the third guide slope on the wall surface near the lifting groove.

[0019] In one embodiment, the terminal assembly includes a main body portion and a locking portion connected to each other, the locking portion and the stop member being disposed on the side of the main body portion near the terminal locking member;

[0020] The housing is provided with a limiting wall that extends along a first direction. The locking portion is used to abut against the limiting wall to restrict the terminal assembly from exiting the mounting port. The first direction is perpendicular to the length direction of the terminal assembly.

[0021] In one embodiment, the terminal assembly further includes terminals and wire retainers, the terminals and wire retainers being respectively disposed at opposite ends of the main body portion in the length direction of the housing, the terminals being used to connect to terminals of the connector socket.

[0022] In one embodiment, the housing has a plug-in interface opposite to the mounting port, the plug-in interface is connected to the mounting cavity, and the plug-in interface is used for power supply connector female socket insertion;

[0023] The upper wall of the housing is arched to form a sloping protrusion. The height of the sloping protrusion gradually decreases from the insertion interface toward the middle of the housing. The inner wall of the sloping protrusion is provided with anti-foolproof ribs.

[0024] In one embodiment, a wall recess in the housing opposite to the ramp protrusion forms a foolproof groove.

[0025] This utility model also proposes an electrical connector, including a connector female and a connector male as described above, wherein the connector female is used for insertion and mating with the connector male.

[0026] This invention combines a terminal locking component and a housing into a single module. The terminal locking component is movably connected to the housing, providing both a pre-pressed position and a locked position. Through the cooperation of a limiting part and a limiting portion, in the pre-pressed position, the limiting portion mates with the limiting part, and the locking part is spaced apart from the stop. In the locked position, the limiting portion is closer to the terminal assembly, and the locking part extends into the mounting cavity and abuts against the stop, preventing the terminal assembly from exiting the mounting opening. During assembly, the terminal locking component is first installed in the pre-pressed position for temporary fixation, at which point it does not lock the terminal assembly. The connector male is then packaged and transported to the user. After the user completes the wiring process, the terminal assembly is inserted into the mounting cavity, and finally, the terminal locking component is pressed into the locked position to complete the fixation. During this process, the terminal locking component is pre-assembled in the pre-pressed position at the factory, eliminating the need for manual alignment by the user and saving on alignment steps, thus improving the installation efficiency of the connector male.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0042] refer to Figure 1 As shown in the figure, this utility model proposes a male connector 100, including a housing 10, a terminal assembly 20, and a terminal locking member 30. The housing 10 is provided with a limiting part 11, and the housing 10 has an installation port 12a and an installation cavity 13a. The terminal assembly 20 is installed in the installation cavity 13a through the installation port 12a, and the terminal assembly 20 includes a stop member 21. The terminal locking member 30 is movably connected to the housing 10. The terminal locking member 30 includes a limiting mating part 31 and a locking part 32 connected to each other. The limiting mating part 3131 includes an upper limiting block 311 and a lower limiting block 312 spaced apart along a first direction. The upper limiting block 311, the lower limiting block 312, and the limiting part 11 all extend along a second direction. The first direction is perpendicular to the second direction. The housing 10 is elongated, the second direction is the width direction of the housing 10, and the first direction is the height direction of the housing 10. The terminal locking member 30... Terminal assembly 20 has a pre-pressed position and a locked position. In the pre-pressed position, the upper limit block 311 and the lower limit block 312 clamp the limiting part 11 so that the locking part 32 and the stop member 21 are spaced apart. In the locked position, the upper limit block 311 is located on the side of the limiting part 11 close to the terminal assembly 20 so that when the terminal locking member 30 is pressed in the first direction, the upper limit block 311 squeezes and expands the limiting part 11, so that the locking part 32 extends into the mounting cavity and abuts against the stop member 21 to restrict the terminal assembly 20 from exiting the mounting port 12a.

[0043] In this embodiment, the housing 10 is the outer shell of the male connector 100, which can be made of an insulating material such as plastic, and its overall shape is a long rectangular shape. The mounting port 12a is opened on the side wall of the housing 10, and the mounting cavity 13a is connected to the mounting port 12a.

[0044] Terminal assembly 20 is the part of the connector used to achieve electrical connection, and is typically made of a conductive metal material such as copper or brass. Terminal assembly 20 is installed from mounting port 12a into mounting cavity 13a along the length of housing 10.

[0045] Terminal locking member 30 is used to secure terminal assembly 20, preventing it from moving out of mounting cavity 13a during assembly. Terminal locking member 30 is generally movably connected to housing 10, meaning it can move relative to housing 10. For example, terminal locking member 30 has a pre-pressed position and a locked position, thus providing pre-pressing and locking functions to ensure efficient installation of terminal locking member 30 and housing 10, as well as stability of terminal assembly 20 after installation. Terminal locking member 30 may be made of insulating material such as plastic and can be snapped onto housing 10.

[0046] The limiting part 11 is a structure within the housing 10 used to limit the position of the terminal locking member 30, ensuring that the terminal locking member 30 is in the pre-compression position or the locked position. For example, when the terminal locking member 30 is in the pre-compression position, the limiting mating part 31 engages with the limiting part 11, thereby achieving a limiting connection between the two and preventing the terminal locking member 30 from shifting. However, the locking part 32 and the stop member 21 remain spaced apart, allowing the terminal assembly 20 to be freely inserted. Specifically, the limiting mating part 31 is a protruding structure of the terminal locking member 30. The upper limiting block 311 and the lower limiting block 312 limit the movement of the terminal locking member 30 by changing their relative positions.

[0047] The locking part 32 can be the portion of the terminal locking member 30 extending towards the terminal assembly 20, and the stop member 21 can be a structure of the terminal assembly 20 protruding towards the terminal locking member 30, used to cooperate with the locking part 32 to prevent the terminal assembly 20 from falling off the housing 10 during installation or use. In the pre-pressed position, the locking part 32 and the stop member 21 are spaced apart to ensure that the terminal locking member 30 does not lock the terminal assembly 20 in the pre-pressed position, and the terminal assembly 20 can be freely inserted for easy installation; in the locked position, the locking part 32 and the stop member 21 abut against each other to prevent the terminal assembly 20 from exiting the mounting port 12a, thereby locking the terminal assembly 20 and ensuring the stability and safety of the connector. Specifically, in the pre-pressed position, the upper limit block 311 and the lower limit block 312 clamp the limiting part 11, preventing the locking part 32 from extending into the mounting cavity 13a. In the locked position, the upper limit block 311 is located on the side of the limiting part 11 closest to the terminal assembly 20. When the terminal locking member 30 is pressed, the upper limit block 311 compresses and expands the limiting part 11, thereby pushing the locking part 32 into the mounting cavity 13a, where it contacts the stop member 21, locking the terminal assembly 20. This improves the assembly efficiency of the connector male 100. For example, during assembly, the terminal assembly 20 is easily inserted into the housing 10. In the pre-pressed position, the terminal assembly 20 is in an adjustable state. When the terminal locking member 30 is pressed to the locking position, the cooperation between the limiting block and the limiting part 11 automatically locks the terminal assembly 20, thereby avoiding the need for the user to manually align or insert other auxiliary fixing parts, greatly simplifying the assembly process and improving production efficiency.

[0048] This invention combines the terminal locking member 30 and the housing 10 into a single module. The terminal locking member 30 is movably connected to the housing 10, giving it a pre-pressed position and a locked position. Through the cooperation of the limiting part 11 and the limiting part 31, when the terminal locking member 30 is in the pre-pressed position, the limiting part 31 mates with the limiting part 11, and the locking part 32 is spaced apart from the stop member 21. When in the locked position, the limiting part 31 is positioned near the side of the terminal assembly 20, and the locking part 32 extends into the mounting cavity 13a and abuts against the stop member 21, preventing the terminal assembly 20 from exiting the mounting opening 12a. During assembly, the terminal locking element 30 is first installed in the pre-compression position to provide temporary fixation. At this time, it does not lock the terminal assembly 20. Then, the connector male 100 is packaged and transported to the user. After the user completes the wiring steps, the terminal assembly 20 is inserted into the mounting cavity 13a. Finally, the terminal locking element 30 is pressed into the locking position to complete the fixation. In this process, the terminal locking element 30 of the electrical connector 300 is already assembled in the pre-compression position at the factory, so the user does not need to manually align the terminal locking element, thus saving the user the alignment and installation steps and improving the installation efficiency of the connector male 100.

[0049] In one embodiment, the terminal locking member 30 further includes a body portion 33, an upper limit block 311 and a lower limit block 312 protruding from the side wall of the body portion 33, and a locking portion 32 protruding from the bottom wall of the body portion 33 near the terminal assembly 20.

[0050] The mounting cavity 13a is provided with a boss 14, and the side wall of the body part 33 extends toward the terminal assembly 20 to form a positioning part 34. In the locked position, the positioning part 34 abuts against the boss 14 to restrict the terminal locking member 30 from being pressed against the terminal assembly 20 in the first direction.

[0051] In this embodiment, the boss 14 is a protruding component within the mounting cavity 13a, protruding from the bottom of the mounting cavity 13a, and is used to cooperate with the positioning part 34 of the terminal locking member 30, thereby restricting the movement of the terminal locking member 30. When the terminal locking member 30 is in the locked position, the contact between the positioning part 34 and the boss 14 provides a physical restriction, preventing the terminal locking member 30 from further pressing the terminal assembly 20 along the first direction, thereby avoiding excessive pressure on the terminal locking member 30 and protecting the terminal assembly 20 from damage. The user only needs to press the terminal locking member 30 to the locked position, without additional positioning or adjustment steps, which greatly simplifies the assembly process and improves production efficiency.

[0052] In one embodiment, the limiting part 11 is provided with a first guide slope 111 away from the wall surface of the terminal assembly 20. The first guide slope 111 is inclined from the outer wall surface of the housing 10 toward the terminal assembly 20 and toward the outer side of the housing 10. The upper limit block 311 and the lower limit block 312 are both provided with a second guide slope 313 that cooperates with the first guide slope 111 on the wall surface near the terminal assembly 20.

[0053] In this embodiment, the first guide ramp 111 is a ramp of the limiting part 11 inside the housing 10. Its function is to guide the terminal locking member 30 to move smoothly in a certain direction, so as to ensure that the terminal locking member 30 can smoothly enter its locking position. The first guide ramp 111 is provided on the wall surface of the limiting part 11 opposite to the terminal assembly 20, and is inclined from the outer wall surface of the housing 10 towards the terminal assembly 20, forming a gradual ramp. In this way, when the terminal locking member 30 is inserted, the upper limit block 311 and the lower limit block 312 can slide smoothly and align to the locking position, reducing friction and resistance caused by incorrect angle or inaccurate insertion. Secondly, the design of the second guide ramp 313 allows the upper limit block 311 and the lower limit block 312 to cooperate parallel with the first guide ramp 111 inside the housing 10 during the insertion process, ensuring that the terminal locking member 30 smoothly enters the mounting cavity 13a of the housing 10 and finally reaches the correct locking position.

[0054] In one embodiment, a lifting groove 35 is provided on the side of the terminal locking member 30 away from the terminal assembly 20. The groove wall of the lifting groove 35 is used to be lifted so that the terminal locking member 30 is switched from the locked position to the pre-pressed position.

[0055] In this embodiment, the lifting groove 35 is a groove-shaped structure provided on the terminal locking member 30, located on the side of the terminal locking member 30 away from the terminal assembly 20. Its function is to allow the terminal locking member 30 to switch from the locked position to the pre-compression position by applying pulling force manually or mechanically. By providing the lifting groove 35, the terminal locking member 30 can be switched from the locked position to the pre-compression position by a simple lifting operation without disassembling the connector. In this way, the terminal locking member 30 can return to an unlocked state, facilitating the disassembly or adjustment of the terminal assembly 20.

[0056] In one embodiment, the limiting part 11 is provided with a third guide slope 112 near the wall of the terminal assembly 20. The third guide slope 112 is inclined from the inside of the housing 10 to the outside and faces the terminal assembly 20. The lower limiting block 312 is provided with a fourth guide slope 314 near the wall of the lifting groove 35, which cooperates with the third guide slope 112.

[0057] In this embodiment, the design of the third guide ramp 112 and the fourth guide ramp 314 ensures that the terminal locking member 30 slides along the correct trajectory during lifting. This guiding effect reduces the resistance and friction of the terminal locking member 30, making the lifting operation smoother and more stable. Through this coordinated design of the guide ramps, operators can more easily switch from the locked position to the pre-pressed position when lifting the terminal locking member 30. Whether operated manually or on an automated production line, the smoothness of the lifting process is significantly improved, reducing the risk of human error and improper assembly.

[0058] In one embodiment, the terminal assembly 20 includes a main body 22 and a locking part 23 connected to each other. The locking part 23 and the stop member 21 are disposed on the side of the main body 22 near the terminal locking member 30. The housing 10 is provided with a limiting wall 113, which extends along a first direction. The locking part 23 is used to abut against the limiting wall 113 to restrict the terminal assembly 20 from exiting the mounting port 12a. The housing 10 is elongated, and the first direction, the length direction of the housing 10, and the width direction of the housing 10 are perpendicular to each other.

[0059] In this embodiment, the limiting wall 113 extends in a first direction, providing a physical position to ensure that the terminal assembly 20 cannot easily detach from the mounting opening 12a of the housing 10. The locking part 23 can be a spring piece, having a first end and a second end. The first end is connected to the top wall of the main body 22, and the second end is spaced apart from the main body 22. When the terminal assembly 20 is inserted into the mounting cavity 13a, the second end abuts against the main body 22 to smoothly pass through the limiting wall 113. After the locking part 23 smoothly passes through the limiting wall 113, the second end springs upward to abut against the limiting wall 113, thereby restricting the terminal assembly 20 from exiting the mounting opening 12a. Thus, when the connector male head 100 is initially packaged, i.e., when the terminal locking member 30 is in the pre-pressed position, the terminal assembly 20 will not easily detach from the mounting opening 12a, improving the stability of the terminal assembly 20. When the terminal assembly 20 needs to be pulled out, the locking part 23 can be pulled out by bending backward.

[0060] In one embodiment, the terminal assembly 20 further includes a terminal 24 and a wire-holding member 25. The terminal 24 and the wire-holding member 25 are respectively disposed at opposite ends of the main body 22 along the length of the housing 10. The terminal 24 is used to connect with the terminal 24 of the connector female 200. In this embodiment, the terminal assembly 20 includes the terminal 24 and the wire-holding member 25, so that the terminal assembly 20 can not only connect to the connector female 200, but also fix the cable.

[0061] In one embodiment, the housing 10 has a plug-in interface 15a opposite to the mounting port 12a. The plug-in interface 15a is connected to the mounting cavity 13a and is used for the power supply connector 300 female socket 200 to be plugged in. The upper wall surface of the housing 10 is arched to form a ramp protrusion 16. The height of the ramp protrusion 16 gradually decreases from the plug-in interface 15a toward the middle of the housing 10. The inner wall surface of the ramp protrusion 16 is provided with anti-fooling ribs 17.

[0062] In this embodiment, the insertion interface 15a is an interface on the housing 10 specifically designed for inserting the electrical connector female socket 200. It communicates with the mounting cavity 13a, forming an electrical connection channel between the socket and the plug. The ramp protrusion 16 is a structure with a gradually decreasing height formed on the upper wall of the housing 10, gradually sloping towards the center of the housing 10. This gradient design forms a guide surface, helping the connector female socket 200 to be more accurately aligned during insertion, avoiding the possibility of incorrect insertion. The ramp protrusion 16 provides a natural guiding effect, enabling the socket to automatically align, reducing insertion problems caused by improper operation.

[0063] The anti-misalignment rib 17 is located on the inner wall of the ramp protrusion 16 and serves to prevent incorrect mating during socket insertion. Its design prevents the connector female 200 from being incorrectly inserted into a mismatched position within the housing 10, thereby improving the reliability and stability of the entire connection process. This ensures correct mating through physical barriers or guidance, avoiding malfunctions caused by incorrect socket orientation.

[0064] Furthermore, the wall recesses opposite to the ramp protrusion 16 of the housing 10 form a foolproof groove 18. The cooperation between the foolproof groove 18 and the ramp protrusion 16 provides another layer of physical protection, preventing mismatched insertion between the socket and the housing 10. When the socket is inserted, the foolproof groove 18 guides the socket into the correct direction, ensuring that the connection between the two is correct.

[0065] This utility model also proposes an electrical connector 300, which includes a connector female socket 200 and a connector male head 100. The specific structure of the connector male head 100 is as described in the above embodiments. Since this electrical connector 300 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The connector female socket 200 is used for mating with the connector male head 100.

[0066] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
