Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and in particular to an electrical connector that can form a self-locking mechanism after the socket and plug are mated, and can maintain an effective and stable connection signal under high-frequency vibration environment. Background Technology

[0002] In electrical connectors, maintaining a secure fit between the plug and socket effectively ensures stable connection signals.

[0003] Currently, Chinese invention patent CN111934137B discloses an electrical connector, its manufacturing method, and a locking component. The electrical connector includes a first connector (plug connector) mounted at the front end of a cable and a locking component mounted on the first connector. The first connector has a conductive first contact that is electrically connected to a contact of a second connector (receptacle connector), which is a peer connector. The first contact has a cylindrical fitting portion that engages with the contact of the second connector, and a cover portion that closes and covers one side of the opening of the fitting portion. The outer diameter of the fitting portion is configured to expand when inserted or removed relative to the contact of the second connector. The locking component has a flat plate portion that covers the cover portion; a pair of arms that face the flat plate portion in the fitting direction of the first and second connectors and extend parallel to the flat plate portion in the axial direction of the cable; and guide portions that extend from both ends of the pair of arms in the flat plate portion in the direction of the connector width towards the pair of arms in the fitting direction. The upper extension and the positioning part, at a position further back from the front end of the cable toward the base end of the cable than the guide part, extend from both ends of the connector width direction in the flat part along the mating direction. The pair of arms do not have portions that extend further back in the axial direction of the cable than the rear end of the guide part, and when the mating part that is mated to the contact of the second connector is removed, it clamps the mating part from the radial outside, thereby limiting the expansion diameter of the mating part. In the restricted state where the pair of arms restrict the expansion diameter of the mating part, the positioning part faces the rear part of the first connector located further back than the mating part in the connector width direction, suppressing the movement of the rear part in the connector width direction. The locking member is mounted on the first connector in such a way that it can move between the restricted state position and the standby state position where the pair of arms do not restrict the expansion diameter of the mating part, and when the locking member moves in the movement direction, the positioning part abuts against a part of the first connector, thereby suppressing further movement of the locking member in the movement direction.

[0004] In summary, while conventional electrical connectors in the prior art can achieve a secure connection between the plug connector (i.e., the first connector) and the socket connector (i.e., the second connector) through conventional locking components, thus enabling effective and stable signal connections, these conventional electrical connectors lack a pre-assembly stage (the stage where the conventional locking components are pre-installed into the plug to form a pre-assembled unit) or do not restrict the movement freedom of the conventional locking components in the axial direction of the cable, the width direction of the connector, and the mating direction of the first and second connectors during the pre-assembly stage. As a result, conventional electrical connectors in the prior art can only ship the plug connector and conventional locking components haphazardly to the end customer, requiring the end customer to install the plug connector, conventional locking components, and socket connector themselves. This increases the end customer's assembly costs and difficulty. Furthermore, if the end customer's assembly is not up to standard, the connection between the plug connector and the socket connector may be unstable or unreliable, causing the conventional electrical connector to be unable to maintain an effective and stable signal connection in complex environments such as high-frequency vibration. Utility Model Content

[0005] The electrical connector provided by this utility model aims to solve at least some of the defects of existing electrical connectors.

[0006] This utility model provides an electrical connector. The electrical connector includes a socket with a self-locking groove and a plug with a housing, and further includes:

[0007] A locking component, comprising a base, a piercing structure, a limiting structure, and a locking structure, wherein the limiting structure is located between the piercing structure and the locking structure, and the base has a pair of side plates in a first direction;

[0008] The puncture structure is formed by stamping at least a portion of the side plate and protrudes toward the interior of the substrate along the first direction;

[0009] The limiting structure is formed by at least a partial bending of the side plate, and bends inward toward the interior of the base along the first direction, and encloses the side plate to form a track space;

[0010] The housing has a flat cover, a hollow cylindrical fitting part, and a pair of bent track parts, and the pair of track parts are respectively disposed on the opposite two sides of the cover in the first direction.

[0011] The fitting portion protrudes from the middle position of the cover portion along the second direction, and the track portion protrudes from the edge position of the cover portion along the second direction;

[0012] The fitting part is provided with a locking groove and a self-locking protrusion at one end opposite to the cover part in the second direction. The locking groove is recessed into the outer cylindrical surface of the fitting part along the circumference of the fitting part, and the self-locking protrusion protrudes from the inner cylindrical surface of the fitting part along the circumference of the fitting part.

[0013] When the locking component is pre-installed into the plug to form a pre-assembly unit along a third direction, the track portion can sequentially pass through the piercing structure and the limiting structure to enter the track space to guide the locking component to move along the third direction. At this time, the side of the track portion away from the fitting portion in the first direction abuts against the side plate, the side of the track portion away from the cover portion in the second direction abuts against the limiting structure, and the side of the piercing structure close to the limiting structure in the third direction abuts against the track portion to restrict the degree of freedom of movement of the locking component in the pre-assembly unit in the first direction, the second direction, and the third direction.

[0014] When the plug in the pre-assembled unit is inserted into the socket, the self-locking protrusion engages with the self-locking groove. At this time, an external force is applied to the locking component to force the locking component to move along the third direction until the locking structure engages with the locking groove.

[0015] The first direction, the second direction, and the third direction are orthogonal to each other, and the second direction is the mating direction of the plug and the socket.

[0016] In some embodiments, the piercing structure is wedge-shaped, and the surface of the piercing structure facing the interior of the substrate is inclined.

[0017] The inclined surface has a first side and a second side opposite to each other in the third direction, and the first side is close to the limiting structure;

[0018] The first side and the side plate have a preset first height in the first direction, and the second side and the side plate have a preset second height in the first direction;

[0019] The first height is greater than the second height.

[0020] In some embodiments, the puncture structure and the side plate are integrally formed, and the limiting structure and the side plate are integrally formed.

[0021] In some embodiments, the plug further includes:

[0022] The plug body is embedded inside the housing, and the plug body is provided with signal terminals inside;

[0023] A cable, one end of which is connected to the plug body and communicates with the signal terminal, and the other end of which extends in a direction away from the plug body along the third direction.

[0024] In some embodiments, the socket includes:

[0025] A hollow cylindrical fitting protrusion is provided inside the fitting protrusion, which is adapted to the signal terminal, and the self-locking groove is recessed into the outer cylindrical surface of the fitting protrusion.

[0026] A grounding component in the shape of a flat plate, wherein the fitting protrusion protrudes from the grounding component along the second direction;

[0027] When the plug is inserted into the socket, the signal pin can be inserted into the signal terminal, at which time the signal pin is connected to the signal terminal.

[0028] In some embodiments, the substrate further includes:

[0029] A base plate that abuts against the cover to support the housing;

[0030] The top plate, wherein the locking structure is formed by at least partial stamping of the top plate;

[0031] The pair of side plates, the bottom plate, and the top plate are integrally formed.

[0032] In some embodiments, the locking structure includes:

[0033] The arc-shaped part, a pair of clamping arms, and a pair of anti-reverse steps;

[0034] One of the pair of clamping arms is respectively connected to one of the pair of anti-reverse steps and one end of the arc-shaped portion;

[0035] The other clamping arm of the pair of clamping arms is respectively connected to the other anti-reverse step of the pair of anti-reverse steps and the other end of the arc-shaped portion;

[0036] The arc-shaped portion, the pair of clamping arms, and the pair of anti-reverse steps together enclose and form a locking space.

[0037] In some embodiments, the locking component in the pre-assembled unit can move a preset target distance along the third direction to make the locking component reach a preset locking position. At this time, a pair of clamping arms are engaged in the locking groove, and the arc-shaped portion and a pair of anti-retraction steps together restrict the housing from disengaging from the locking space.

[0038] In some embodiments, the cover portion is provided with a preset first positioning structure on the surface of the fitting portion facing away from the fitting portion in the second direction;

[0039] A notch is provided in the middle of the base plate, the notch extends through the two opposite sides of the base plate in the second direction, and the notch can expose the first positioning structure;

[0040] The base plate is provided with a preset second positioning structure, and the second positioning structure is located on both sides of the notch in the first direction;

[0041] When the locking component in the pre-assembled unit moves upward in the third direction and the first positioning structure and the second positioning structure correspond, it can be determined that the locking component has reached the locking position.

[0042] In some embodiments, the clamping arm is provided with rounded corners, and at least a portion of the side plate and the bottom plate are provided with chamfers on the side of the third direction away from the arcuate portion.

[0043] At least one beneficial effect of the electrical connector provided by this utility model embodiment is that it proposes a novel electrical connector that achieves a stable connection between the plug and the socket by employing a locking component with a piercing structure, a limiting structure, and a locking structure. The piercing structure and the limiting structure restrict the locking component's movement freedom in the first, second, and third directions when it is pre-installed into the plug to form a pre-assembly unit, preventing the locking component and the plug in the pre-assembly unit from detaching during packaging and shipping to the end customer, thereby reducing the end customer's assembly cost and assembly difficulty. Furthermore, during the final assembly of the pre-assembly unit, the user first installs the socket onto the plug in the pre-assembly unit until the self-locking protrusion engages with the self-locking groove to form a self-lock, and then pushes the locking component in the pre-assembly unit until the locking structure engages with the locking groove to form a reliable fixation. In summary, this electrical connector can form a self-lock after the socket and plug are mated, and can maintain an effective and stable connection signal under high-frequency vibration environments.

[0064] In the following description, such as Figures 1-9 As shown, the following situation exists: the first direction, the width direction of the locking member 100 or the base 11 is set as the X direction, the third direction, the axial direction of the cable, and the length direction of the locking member 100 or the base 11 are set as the Y direction, and the second direction, the mating direction of the socket 200 and the plug 300, the thickness direction of the locking member 100 or the base 11, the axial direction of the mating part 312, and the axial direction of the mating protrusion 21 are set as the Z direction; wherein, the X direction, the Y direction, and the Z direction are orthogonal to each other.

[0065] It should be noted that the electrical connector 1000 can electrically connect the signal transmission medium such as the cable 33 to the circuit of the substrate, such as an RF (Radio Frequency) connector; wherein, the so-called signal transmission medium refers to the medium used to transmit various signals; in addition, the substrate is, for example, a printed wiring substrate; that is, the electrical connector 1000 of this embodiment is an RF connector that electrically connects the RF cable to the circuit of the printed wiring substrate.

[0066] It is understood that the plug 300 engages with the socket 200, which is mounted on the substrate as an object connector, thereby electrically connecting the cable 33 to the circuitry of the substrate.

[0067] Generally speaking, the socket 200 is located at the end customer's location, so the plug 300 and locking component 100 need to be pre-installed before packaging and shipping to the end customer.

[0068] Specifically, the end of the locking component 100 that is close to the piercing structure 12 in the Y direction is designated as the front end, and the end of the locking component 100 that is opposite to the front end in the Y direction is designated as the rear end.

[0069] In addition, the direction from the front end to the rear end will be described as the rear; during the pre-installation process, the plug 300 enters the interior of the base 11 from the front end and passes through the piercing structure 12, the limiting structure 13 and the locking structure 14 in sequence, and finally reaches the preset locking position at the rear.

[0070] Furthermore, the side of the locking member 100 where the bottom plate 112 is located in the Z direction and the side of the housing 31 where the cover 311 is located in the Z direction are positioned downwards, and the side of the locking member 100 where the top plate 113 is located in the Z direction and the side of the housing 31 where the locking groove 3121 is located in the Z direction are positioned upwards.

[0071] Specifically, the area where the puncture structure 12 and the limiting structure 13 are located is defined as the pre-installation area, and the area where the locking structure 14 is located is defined as the final installation area.

[0072] Please see Figures 1-7 The electrical connector 1000 includes a socket 200 having a self-locking groove 211 and a plug 300 having a housing 31.

[0073] Specifically, the aforementioned electrical connector 1000 also includes a locking component 100.

[0074] In this embodiment, the materials used to manufacture the locking component 100 include, but are not limited to, SUS304-1 / 2H250-310Hv, SUS301-H350-450HV, SUS301EH430-530HV, and other materials with a preset elastic modulus and preset stiffness; wherein, SUS304-1 / 2H250-310Hv is a semi-hardened 304 stainless steel with a hardness range between 250 and 310 Vickers hardness; SUS301-H350-450HV is a hardened 301 stainless steel with a hardness range between 350 and 450 Vickers hardness; SUS301EH430- 530HV is a type of 301 stainless steel that has undergone a stronger hardening treatment, with a hardness range between 430 and 530 Vickers hardness. In addition, the material used to make the locking part 100 usually has a certain degree of hardness and corrosion resistance, and the thickness of the material used to make the locking part 100 is, but is not limited to, 0.10 mm, 0.12 mm, 0.15 mm and 0.20 mm.

[0075] The locking component 100 includes: a base 11, a piercing structure 12, a limiting structure 13, and a locking structure 14.

[0076] In addition, the limiting structure 13 is located between the piercing structure 12 and the locking structure 14, and the base 11 has a pair of side plates 111 in the X direction.

[0077] Furthermore, the puncture structure 12 is formed by stamping at least a portion of the side plate 111 and protrudes into the interior of the base 11 along the X direction.

[0078] Specifically, the limiting structure 13 is formed by at least a partial bending of the side plate 111, and bends inward toward the base 11 in the X direction, and encloses the side plate 111 to form a track space.

[0079] To further explain, the housing 31 has a cover portion 311 in the shape of a flat plate, a fitting portion 312 in the shape of a hollow cylinder, and a pair of track portions 313 in the shape of a bent plate, and the pair of track portions 313 are respectively disposed on the opposite two sides of the cover portion 311 in the X direction.

[0080] It should be noted that the track section 313 can enter the aforementioned track space to guide the locking component 100 to move in the Y direction; in other words, the track section 313 entering the track space allows the housing 31 to enter the aforementioned pre-assembly area and final assembly area more smoothly.

[0081] In this embodiment, the fitting portion 312 protrudes from the middle position of the cover portion 311 along the Z direction, and the track portion 313 protrudes from the edge position of the cover portion 311 along the Z direction.

[0082] In other words, since the interior of the fitting part 312 is hollow, the fitting part 312 has openings at both opposite ends in the Z direction, and the cover part 311 covers the opening below the fitting part 312 in a closed manner.

[0083] It is understood that the fitting part 312 is provided with a locking groove 3121 and a self-locking protrusion 3122 at the end opposite to the cover part 311 in the Z direction. The locking groove 3121 is recessed into the outer cylindrical surface of the fitting part 312 along the circumference of the fitting part 312, and the self-locking protrusion 3122 protrudes from the inner cylindrical surface of the fitting part 312 along the circumference of the fitting part 312.

[0084] It should be noted that when the locking component 100 is pre-installed into the plug 300 along the Y direction to form the pre-assembly unit 1001, the track portion 313 can sequentially pass through the piercing structure 12 and the limiting structure 13 to enter the track space to guide the locking component 100 to move along the Y direction. At this time, the side of the track portion 313 away from the fitting portion 312 in the X direction abuts against the side plate 111, the side of the piercing structure 12 close to the limiting structure 13 in the Y direction abuts against the track portion 313, and the side of the track portion 313 away from the cover portion 311 in the Z direction abuts against the limiting structure 13 to restrict the degree of freedom of movement of the locking component 100 in the X, Y and Z directions in the pre-assembly unit 1001.

[0085] Specifically, the process of matching the plug 300 in the pre-assembly unit 1001 with the socket 200 at the end customer is called terminal assembly.

[0086] In this embodiment, restricting the movement freedom of the locking component 100 in the X, Y and Z directions in the pre-assembly unit 1001 can prevent the pre-assembly unit 1001 from becoming scattered during the packaging and shipping process to the end customer, thereby avoiding the need for the end customer to reassemble the plug 300 and the locking component 100 during the terminal assembly process, and thus reducing the assembly cost and assembly difficulty for the end customer.

[0087] In summary, the piercing structure 12, the limiting structure 13, and the locking structure 14 are arranged sequentially in the Y direction; in other words, the piercing structure 12 is located closer to the front end, while the locking structure 14 is located closer to the rear end, and the limiting structure 13 is located between the piercing structure 12 and the locking structure 14.

[0088] Specifically, when the socket 200 at the end customer is installed above the plug 300 in the pre-assembled unit 1001, the self-locking protrusion 3122 engages with the self-locking groove 211. At this time, an external force is applied to the locking member 100 to force the locking member 100 to move in the Y direction until the locking structure 14 engages with the locking groove 3121.

[0089] It should be noted that the plug 300 and locking component 100 of this electrical connector 1000 need to be pre-assembled to form an integrated pre-assembly unit 1001. Then, the pre-assembly unit 1001 is packaged and shipped to the end customer. After the end customer mates the plug 300 and socket 200 in the pre-assembly unit 1001, the locking component 100 in the pre-assembly unit 1001 is pushed to move further back along the Y direction until it enters the locking space formed by the locking structure 14. This causes the clamping arm 142 in the locking structure 14 to clamp the mating part 312, thereby making the plug 300 and socket 200 self-locking after mating. Finally, the electrical connector 1000 can maintain an effective and stable signal connection even in complex environments.

[0090] In some embodiments, combined with Figure 1 , Figure 4 and Figure 5 It can be seen that the piercing structure 12 is wedge-shaped, and the surface of the piercing structure 12 facing the interior of the substrate 11 is an inclined surface 121.

[0091] Specifically, the inclined surface 121 has a first side 1211 and a second side 1212 in the Y direction, and the first side 1211 is close to the limiting structure 13.

[0092] To further explain, the first side 1211 and the side plate 111 have a preset first height in the X direction, and the second side 1212 and the side plate 111 have a preset second height in the X direction.

[0093] In this embodiment, the first height is greater than the second height, so the piercing structure 12 is wedge-shaped with a lower front and a higher rear, so as to guide the locking component 100 to be pre-installed into the housing 31.

[0094] In some embodiments, refer to Figure 4 and Figure 5 It can be seen that the puncture structure 12 and the side plate 111 are integrally formed, and the limiting structure 13 and the side plate 111 are integrally formed.

[0095] In some embodiments, according to Figure 1 , Figure 2 and Figure 6 It can be seen that the plug 300 also includes: plug body 32 and cable 33.

[0096] It is understandable that the plug body 32 is embedded inside the housing 31, and the plug body 32 is provided with signal terminals 321.

[0097] It should be noted that one end of the cable 33 is connected to the plug body 32 and communicates with the signal terminal 321, and the other end of the cable 33 extends in the Y direction away from the plug body 32.

[0098] In some embodiments, by Figure 2 and Figure 7 It is known that the socket 200 includes: a hollow cylindrical fitting protrusion 21 and a flat grounding component 22.

[0099] The mating protrusion 21 has a signal pin 2001 that is compatible with the signal terminal 321 inside, and the self-locking groove 211 is recessed into the outer cylindrical surface of the mating protrusion 21.

[0100] In addition, the fitting protrusion 21 protrudes from the grounding component 22 along the Z direction.

[0101] Furthermore, when the plug 300 is inserted into the socket 200, the signal pin 2001 can be inserted into the signal terminal 321. At this time, the signal pin 2001 is connected to the signal terminal 321, thereby forming a communication connection between the cable 33 and the circuit of the substrate.

[0102] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 6 The base 11 also includes a bottom plate 112 and a top plate 113.

[0103] Specifically, the base plate 112 can abut against the cover 311 to support the housing 31.

[0104] It is understood that the locking structure 14 is formed by at least a partial stamping of the top plate 113.

[0105] It should be noted that the pair of side plates 111, bottom plate 112 and top plate 113 are integrally formed structures.

[0106] In some embodiments, such as Figure 5 As shown, the locking structure 14 includes: an arc-shaped portion 141, a pair of clamping arms 142, and a pair of anti-reverse steps 143.

[0107] One of the clamping arms 142 is connected to one of the anti-reverse steps 143 and one end of the arc-shaped part 141.

[0108] In addition, the other clamping arm 142 of the pair of clamping arms 142 is connected to the other anti-reverse step 143 of the pair of anti-reverse steps 143 and the other end of the arc-shaped portion 141.

[0109] In addition, the arc-shaped portion 141, a pair of clamping arms 142, and a pair of anti-reverse steps 143 together enclose and form a locking space.

[0110] It is understandable that when the locking component 100 has been assembled at the end and is in the final assembly area, the arc-shaped part 141 can increase the structural strength while saving size.

[0111] In some embodiments, combined with Figures 1-8 It is known that the locking component 100 in the pre-assembly unit 1001 can move a preset target distance 1002 along the Y direction so that the locking component 100 reaches the preset locking position. At this time, a pair of clamping arms 142 are engaged in the locking groove 3121, and the arc-shaped part 141 and a pair of anti-retraction steps 143 together restrict the housing 31 from leaving the above-mentioned locking space.

[0112] In some embodiments, according to Figures 1-9 It can be seen that the cover portion 311 has a preset first positioning structure 3111 on its surface facing away from the fitting portion 312 in the Z direction.

[0113] In this embodiment of the application, a notch 1121 is provided at the middle position of the base plate 112. The notch 1121 extends through the two opposite sides of the base plate 112 in the Z direction, and the notch 1121 can expose the first positioning structure 3111.

[0114] Specifically, a preset second positioning structure 1122 is provided on the base plate 112, and the second positioning structure 1122 is located on opposite sides of the notch 1121 in the X direction.

[0115] To further explain, when the locking component 100 in the pre-assembly unit 1001 moves in the Y direction and the first positioning structure 3111 and the second positioning structure 1122 correspond, it can be determined that the locking component 100 has reached the locking position.

[0116] In summary, the first positioning structure 3111 and the second positioning structure 1122 facilitate the end user's visual identification of whether the locking component 100 is assembled in place or to check whether the locking component 100 is in a locked state; the locked state can be understood as the terminal assembly state when the locking component 100 reaches the preset locking position.

[0117] It is understood that when the locking component 100 is located in the aforementioned pre-installation area, it indicates that the locking component 100 is in an unlocked state; when the locking component 100 is located in the aforementioned final installation area, it indicates that the locking component 100 is in a locked state.

[0118] In this embodiment of the application, the target distance 1002 can be 1.2 mm, which can be understood as the displacement from the unlocked state to the locked state; and in the locked state, the locking component 100 has a free sliding space 1003 in the Y direction, and the space 1003 can be 0.30 mm.

[0119] In some embodiments, refer to Figure 5 It is known that the clamping arm 142 is provided with a rounded corner 1421, and at least a portion of the side plate 111 and the bottom plate 112 are provided with a chamfer 1101 on the side away from the arc-shaped portion 141 in the Y direction.

[0120] It should be noted that the rounded corner 1421 can prevent wear from plugging and unplugging, and the chamfer 1101 facilitates the guidance of the locking component 100 when it is pre-installed into the plug.

[0121] In summary, the electrical connector provided by this utility model embodiment achieves a secure connection between the plug and socket by employing a locking component with a piercing structure, a limiting structure, and a locking structure. The piercing structure and the limiting structure restrict the locking component's movement freedom in the first, second, and third directions when it is pre-installed into the plug to form a pre-assembly unit. This prevents the locking component and the plug in the pre-assembly unit from detaching during packaging and shipping to the end customer, thereby reducing assembly costs and difficulty for the end customer. Furthermore, during the final assembly of the pre-assembly unit, the user first installs the socket onto the plug in the pre-assembly unit until the self-locking protrusion engages with the self-locking groove to form a self-lock, and then pushes the locking component in the pre-assembly unit until the locking structure engages with the locking groove to form a reliable fixation. In conclusion, this electrical connector can form a self-lock after the socket and plug are mated and can maintain an effective and stable connection signal under high-frequency vibration environments. Therefore, the electrical connector provided by this utility model embodiment has a certain novelty compared to traditional electrical connectors.

[0122] The above description, in conjunction with specific / preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. Those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and all of these fall within the protection scope of the present invention.
