Connector with locked wire pair board

Abstract

This application provides a connector with a locking wire-to-wire plate. In practical use, the conductive terminals are first crimped or soldered to the connecting wires, and then inserted into the housing through the connecting hole. The isolator is inserted vertically into the through slot. After its positioning part engages with the housing, the abutment part extends to the mounting slot and fits against its slot wall, completing position guidance and limiting. At this time, the abutment protrusion is located directly above the connection area between the connecting wire and the conductive terminal, and applies a stable holding force to the connection area perpendicular to the insertion force direction. The force prevents the connection area from being in a free-floating state, but is firmly clamped between the housing and the isolator, completely restricting its lateral displacement space. The lateral pressure applied by the abutment protrusion forms a clamping relationship between the connection and the housing, significantly improving structural stability and preventing the conductive terminals and connecting wires from shaking or colliding with the inner wall of the housing during use. By three-dimensionally limiting and fixing the connection, the connector life is effectively extended.

Description

Technical Field

[0001] This application relates to the field of connectors, and more particularly to a connector with a locking wire pair board. Background Technology

[0002] Connectors are typically used to connect electrical equipment to cables to enable data or electrical transmission. A connector generally consists of a housing, terminals, and connecting cables. The terminals and the ends of the connecting cables are fixed together and then installed into the housing to form a fixed connection for subsequent use.

[0003] Existing terminals and connecting wires are usually fixed by pressing or welding. During the fixing process, there is only one axial force. However, during use, the connector is subjected to not only axial force but also perpendicular force. The connection between the conductive terminal and the connecting wire is in a free state inside the housing. This causes the connection to collide with the inner wall of the housing during shaking. Over time, this collision can damage or detach the connection, rendering the connector unusable.

[0004] Existing connectors use isolators to separate two adjacent terminals. However, the isolators only serve to separate the terminals and cannot fix the connection between the terminals and the connecting wires during use. This results in some wobbling during use, which affects the use of the connector. Utility Model Content

[0005] In view of this, it is necessary to provide a connector with a locking wire pair board to solve the above problems.

[0006] Embodiments of this application provide a connector with a locking wire pair board, comprising:

[0007] The housing has a connecting hole, a mounting groove and a through groove. The connecting hole is connected to the mounting groove and the through groove respectively. The connecting hole is opened along a first direction, and the mounting groove and the through groove are opened perpendicular to the first direction.

[0008] The isolator has a positioning part and an abutting part. The abutting part has a protruding abutting protrusion. The positioning part passes through the through groove and engages with the housing so that the abutting part extends into the mounting groove and abuts against the mounting groove, thereby applying a force perpendicular to the first direction to the conductive terminal and connecting wire in the communicating hole to fix the connection of the conductive terminal and connecting wire.

[0009] In at least one embodiment of this application, there are two positioning parts and multiple abutting parts. A connecting groove is formed between the two positioning parts, and the multiple abutting parts are equidistantly disposed in the connecting groove. Each abutting part is disposed between two adjacent conductive terminals to separate the two adjacent conductive terminals.

[0010] In at least one embodiment of this application, the positioning part is provided with a mounting hole, the mounting hole is opened along the first direction, and both the mounting hole and the communicating groove are provided with abutting protrusions;

[0011] The abutting protrusion abuts against the conductive terminal to fix the conductive terminal between the insulating member and the housing.

[0012] In at least one embodiment of this application, a limiting protrusion and a locking protrusion are provided on the positioning part, and a locking block is provided on the inner wall of the through groove, the locking block being able to engage with the limiting protrusion or the locking protrusion.

[0013] In this process, after connecting the conductive terminals and the connecting wires, the isolator is inserted so that the engaging protrusion engages with the locking block, preventing the isolator from detaching from the housing. This allows the assembled conductive terminals and connecting wires to pass through the connecting hole, the mounting hole, or the mounting groove. The isolator is then pressed together, with it passing through the through groove towards the housing, so that the locking block abuts against the limiting protrusion. The abutting protrusion sequentially fixes multiple conductive terminals between the isolator and the housing.

[0014] In at least one embodiment of this application, the conductive terminal is provided with a first retaining plate, and the communicating hole is provided with a first retaining groove, wherein the first retaining plate engages with the first retaining groove.

[0015] In at least one embodiment of this application, the positioning part has a first positioning surface, the engaging protrusion has a first engaging surface, the first engaging surface is perpendicular to the first positioning surface, and the locking block has a second engaging surface, the second engaging surface is perpendicular to the first positioning surface.

[0016] In at least one embodiment of this application, the connector with locking wire pair board further includes:

[0017] The outer shell has a positioning cavity inside, and both the outer shell and the isolation member are disposed in the positioning cavity and abut against the inner wall of the positioning cavity.

[0018] In at least one embodiment of this application, a second slot is provided on the outer shell, and an elastic plate is provided on the outer shell, the elastic plate engaging with the second slot.

[0019] In at least one embodiment of this application, the outer casing has a through hole, the through hole is connected to the connecting hole, and a conductive terminal extends through the through hole into the connecting hole.

[0020] In at least one embodiment of this application, the housing is provided with a protective block protruding from it, and a conductive terminal is located between two of the protective blocks.

[0021] The connector with a locking wire-to-wire board implemented in this embodiment will have at least the following beneficial effects:

[0022] In practical use, the aforementioned connector with locking wire-to-wire plate involves first crimping or soldering the conductive terminals to the connecting wires, and then inserting them into the housing through the connecting holes. The isolator is inserted vertically into the through slot; after its positioning part engages with the housing, its abutment part extends to the mounting slot and fits against its slot wall, completing position guidance and limiting.

[0023] At this point, the abutting protrusion is positioned directly above the connection area between the connecting wire and the conductive terminal, applying a stable holding force perpendicular to the direction of the insertion force. This force prevents the connection area from being in a free-floating state, instead firmly clamping it between the housing and the spacer, forming a rigid support and completely restricting its lateral displacement.

[0024] By abutting the lateral pressure applied by the protrusion, the connection point is clamped to the housing, which significantly improves the structural stability and prevents the conductive terminals and connecting wires from shaking or colliding with the inner wall of the housing during use.

[0025] By using three-dimensional limiting and fixing at the connection point, the lifespan of the connector is effectively extended and the probability of failure is reduced. Attached Figure Description

[0041] The embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0042] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have an intervening component. When a component is considered to be "placed" on another component, it can be directly placed on the other component or may also have an intervening component. The terms "top," "bottom," "upper," "lower," "left," "right," "front," "back," and similar expressions used in this article are for illustrative purposes only.

[0043] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0044] Embodiments of this application provide a connector 100 with a locking wire pair board, comprising:

[0045] The housing 110 has a connecting hole 110a, a mounting groove 110b and a through groove 110c. The connecting hole 110a is connected to the mounting groove 110b and the through groove 110c respectively. The connecting hole 110a is opened along a first direction A, and the mounting groove 110b and the through groove 110c are opened perpendicular to the first direction A.

[0046] The isolator 120 has a positioning part 121 and an abutting part 122. The abutting part 122 has an abutting protrusion 1221. The positioning part 121 passes through the through groove 110c and engages with the housing 110, so that the abutting part 122 extends into the mounting groove 110b and abuts against the mounting groove 110b, thereby applying a force perpendicular to the first direction A to the conductive terminal 130 and the connecting wire 140 in the connecting hole 110a, so as to fix the connection between the conductive terminal 130 and the connecting wire 140.

[0047] Please refer to Figures 1-8 In this embodiment, in actual use, the conductive terminal 130 is first crimped or welded to the connecting wire 140, and then inserted into the housing 110 through the connecting hole 110a. The isolator 120 is inserted vertically into the through groove 110c. After its positioning part 121 engages with the housing 110, its abutment part 122 extends to the mounting groove 110b and fits against its groove wall, thus completing the position guidance and limiting.

[0048] At this moment, the abutting protrusion 1221 is located directly above the connection area between the connecting line 140 and the conductive terminal 130, and applies a stable holding force to the connection area perpendicular to the direction of the insertion force. The force causes the connection area to no longer be in a free-floating state, but to be firmly clamped between the housing 110 and the spacer 120, forming a rigid support and completely restricting its lateral displacement space.

[0049] By abutting the lateral pressure applied by the protrusion 1221, the connection point and the housing 110 are clamped together, which significantly improves the structural stability and prevents the conductive terminal 130 and the connecting wire 140 from shaking or colliding with the inner wall of the housing 110 during use.

[0050] During vibration, cable pulling, or transportation, traditional connectors often suffer accelerated fatigue damage due to free swaying at the connection point; however, this structure effectively extends the connector's lifespan and reduces the probability of failure by providing three-dimensional limiting and fixing at the connection point.

[0051] The housing 110 serves as the main body for supporting and positioning the entire connector. It has sequentially opened through holes 110a along the first direction A (i.e., the direction of wire insertion force) to allow conductive terminals 130 and connecting wires 140 to pass through the housing 110. The mounting groove 110b and the through groove 110c are opened perpendicular to the first direction A and are used to accommodate the abutment part 122 and the positioning part 121 of the isolator 120, respectively. The three are interconnected to form a three-dimensional interlocking structural channel, so that the conductive elements and the positioning structure cooperate with each other in different directions.

[0052] The isolator 120 is composed of a positioning part 121 and an abutment part 122. The positioning part 121 penetrates the through groove 110c of the housing 110 and engages with the housing 110 to ensure the stable positioning of the isolator 120 in the housing 110. The abutment part 122 extends into the mounting groove 110b perpendicular to the insertion force direction and forms a stable abutment relationship with the groove wall of the housing 110. The abutment part 122 is provided with a protruding structure - an abutment protrusion 1221. After assembly, this structure can abut against the connection between the conductive terminal 130 and the connecting line 140 and apply a lateral support pressure to press the connection between the housing 110 and the isolator 120.

[0053] In at least one embodiment of this application, there are two positioning parts 121 and multiple abutting parts 122. A connecting groove 121a is formed between the two positioning parts 121. The multiple abutting parts 122 are equidistantly disposed in the connecting groove 121a, and any one of the abutting parts 122 is disposed between two adjacent conductive terminals 130 to separate the two adjacent conductive terminals 130.

[0054] Please refer to Figures 1-8 In this embodiment, during the connector assembly process, after the conductive terminal 130 and the connecting wire 140 are crimped or soldered, they are inserted into the communicating hole 110a of the housing 110. Subsequently, the isolator 120 is inserted into the through slot 110c of the housing 110 guided by the double positioning part 121 and engages with the housing 110.

[0055] At this time, the multiple abutment portions 122 in the connecting groove 121a will be inserted together into the gap area between two adjacent conductive terminals 130. Each abutment portion 122 is usually provided with a protruding structure, which can physically limit the range of swing of the terminal and prevent contact or interference between adjacent conductive terminals 130.

[0056] The final structure consists of a housing 110, a conductive terminal 130, and an isolator 120, with the abutment portion 122 sandwiching the housing from the top and bottom, providing lateral positioning and longitudinal limiting, so that the conductive terminal 130 is in a stable supported state in multiple dimensions.

[0057] The dual positioning part 121 structure, together with the through groove 110c of the housing 110, can provide a more secure engagement effect, prevent the isolation part 120 from shifting itself, and enhance the overall structural rigidity of the connector assembly.

[0058] Multiple contact parts 122 are equidistantly arranged and positioned between adjacent terminals to achieve physical isolation between the terminals, significantly reducing electrical interference and short-circuit risk between adjacent channels, making it particularly suitable for high-speed, high-frequency, or high-voltage connector environments.

[0059] The abutment part 122 not only serves as a separator, but also forms a point-like clamp at the connection between the connecting wire 140 and the terminal through its lateral support characteristics, effectively limiting its lateral sway and significantly improving its vibration resistance and fatigue resistance.

[0060] There are two positioning parts 121, that is, each end of the isolator 120 is provided with an independent positioning part 121. These two positioning parts 121 can be inserted into the two through slots 110c on the housing 110 respectively and engage with the housing 110 to ensure that the entire isolator 120 is stably positioned after installation and is not easy to loosen or shift. The dual positioning point setting has stronger installation stability than the single positioning structure and can effectively prevent the isolator 120 from rotating or warping during use.

[0061] The two positioning parts 121 are connected by a connecting groove 121a to form a central bridging area. The connecting groove 121a not only serves as a structural connection, but also provides space and a foundation for the subsequent arrangement of the abutment part 122.

[0062] Inside the connecting groove 121a, there are multiple plate-shaped abutment portions 122. These abutment portions 122 are arranged at equal intervals along the length of the connecting groove 121a. The position of each abutment portion 122 is exactly between two adjacent conductive terminals 130. Its function is to support, separate and laterally limit the connection line 140 or welding point between the terminals. The presence of multiple abutment portions 122 can form point-to-point interval support for the entire conductive terminal 130 arrangement structure, enhancing its overall shock resistance and stability.

[0063] In at least one embodiment of this application, the positioning part 121 is provided with a mounting hole 121b, the mounting hole 121b is opened along the first direction A, and both the mounting hole 121b and the communicating groove 121a are provided with abutting protrusions 123.

[0064] The abutting protrusion 123 abuts against the conductive terminal 130 to fix the conductive terminal 130 between the isolator 120 and the housing 110.

[0065] Please refer to Figures 1-8In this embodiment, the mounting hole 121b is formed on the positioning part 121 and arranged along the insertion force direction, which can match the conductive structure. One of its main functions is to provide space and mounting reference position for the conductive terminal 130 in the insertion direction, and at the same time, it guides the arrangement direction of the abutment protrusion 123 to be consistent with the conductive terminal 130 in terms of structure.

[0066] A protruding structure, the abutting plate 123, is provided in the mounting hole 121b and the connecting groove 121a respectively. During the process of inserting the isolator 120 into the housing 110, the abutting plate 123 will automatically align with the corresponding area of ​​the terminal. After assembly, the abutting plate 123 will make physical contact with the surface of the conductive terminal 130 and structurally press and limit the terminal between the housing 110 and the isolator 120.

[0067] At this time, the conductive terminal 130 is no longer in a free-floating state, but is stably clamped by the double-sided abutment plate 123 structure, forming a stable clamping structure.

[0068] The abutting plate 123 restricts the vertical displacement of the terminal from the top and bottom directions, and the engagement relationship between the mounting hole 121b and the positioning part 121 restricts the lateral sliding. At the same time, due to the presence of multiple abutting parts 122, lateral isolation can also be provided between the terminals, further enhancing the three-dimensional stability of the overall structure.

[0069] The abutting protrusion 123 acts directly on the body of the conductive terminal 130 to achieve clamping and fixing in the vertical direction, which completely solves the problem of the conductive terminal 130 floating or shaking in the housing 110 and greatly improves the stability of the connection structure under mechanical impact or vibration.

[0070] The connection between the conductive terminal 130 and the connecting wire 140 is often a solder joint or crimp joint, which is the most vulnerable part of the entire connector. By using structural clamping force, the stress on this part under working conditions can be reduced, indirectly protecting the solder joint from tearing or fatigue damage, extending its service life, and ensuring the continuous stability of the electrical connection.

[0071] In at least one embodiment of this application, a limiting protrusion 1211 and a locking protrusion 1212 are protruding on the positioning part 121, and a locking block 111 is protruding on the inner wall of the through groove 110c. The locking block 111 can engage with the limiting protrusion 1211 or the locking protrusion 1212.

[0072] After connecting the conductive terminal 130 to the connecting wire 140, the isolator 120 is inserted so that the engaging protrusion 1212 engages with the locking block 111, preventing the isolator 120 from detaching from the housing 110. This allows the combined conductive terminal 130 and connecting wire 140 to pass through the connecting hole 110a, the mounting hole 121b, or the mounting groove 110b. The isolator 120 is then pressed together, with it passing through the through groove 110c towards the housing 110, so that the locking block 111 abuts against the limiting protrusion 1211. The abutting protrusion 123 sequentially fixes multiple conductive terminals 130 between the isolator 120 and the housing 110.

[0073] Please refer to Figures 1-8 In this embodiment, firstly, the spacer 120 is inserted into the through slot 110c of the housing 110. In the initial stage of insertion, the engaging protrusion 1212 on the spacer 120 first engages with the engaging block 111 on the inner wall of the housing 110, at which time the spacer 120 is in a preliminary engaging state.

[0074] In this state, although the isolation component 120 has not yet been pressed into its final position, it already has a basic anti-slip function, which can prevent it from accidentally slipping out during operation.

[0075] After the isolator 120 is initially positioned, the conductive terminal 130 and the connecting wire 140 assembly, which has been crimped or welded, are inserted from the direction of the connecting hole 110a of the housing 110, passing through the mounting hole 121b or the mounting groove 110b, so that the terminal is correctly positioned in the target location area between the isolator 120 and the housing 110.

[0076] Subsequently, an axial pressing force is applied to the isolation member 120, causing it to continue to penetrate deeper into the through groove 110c.

[0077] As the isolator 120 is pressed further in, the limiting protrusion 1211 on it eventually contacts the locking block 111 inside the housing 110 and forms an abutment relationship. At this time, the isolator 120 reaches the final installation depth, the structure is closed, and it can no longer be withdrawn outward.

[0078] At the same time, the abutting protrusion 123 inside the isolation member 120 is also pressed down onto the surface of the conductive terminal 130 during the pressing action, forming a pressing effect on each terminal and firmly fixing them between the housing 110 and the isolation member 120.

[0079] By engaging the engaging protrusion 1212 with the limiting protrusion 1211, the isolation component 120 completes the process from initial positioning to final limiting, effectively avoiding displacement or loosening caused by incomplete insertion or accidental external force.

[0080] After the isolator 120 is pressed to the bottom, its internal abutting protrusion 123 will directly act on the conductive terminal 130 to achieve lateral clamping, enhance the shock resistance and tensile strength of the connection structure, and solve the problem of the terminal floating and swaying in the traditional structure.

[0081] In at least one embodiment of this application, the conductive terminal 130 is provided with a first retaining plate 131, and the communicating hole 110a is provided with a first retaining groove 110d, and the first retaining plate 131 engages with the first retaining groove 110d.

[0082] Please refer to Figures 1-8 In this embodiment, during the assembly process, when the conductive terminal 130 is inserted into the connecting hole 110a along the insertion force direction, the first locking plate 131 will slide past the edge of the first locking groove 110d and generate a certain elastic deformation during the sliding process. When the first locking plate 131 is aligned with the first locking groove 110d, it will automatically embed into the first locking groove 110d due to the structural springback or guiding effect, and achieve locking and fixing. At this time, the terminal cannot continue to move forward or backward along the insertion force direction, thereby completing the axial limiting and anti-dislodgement functions.

[0083] The engagement of the first card plate 131 with the first card slot 110d prevents the conductive terminal 130 from moving freely in the axial direction after it is inserted into place. This effectively avoids problems such as terminal retraction or unstable insertion caused by mechanical pulling, thermal expansion and contraction, or vibration, ensuring connection reliability.

[0084] Since the snap-fit ​​structure usually has automatic positioning and "click" feedback functions, it can be used as a structural judgment standard for insertion into place in actual assembly, which helps to quickly determine whether the terminal is assembled correctly, thereby improving assembly efficiency and yield.

[0085] This locking structure is a self-locking fixation mechanism that eliminates the need for additional screws, retaining rings, gluing, or other secondary processes, simplifying the assembly process, reducing production costs, and improving the overall integration of the structure.

[0086] The first locking plate 131 is a protruding or extended structure on the body of the conductive terminal 130, usually located in the middle or tail end. Structurally, it acts as a retaining shoulder or locking tooth and is the active element for locking connection.

[0087] The housing 110 has a first slot 110d inside the communicating hole 110a that mates with the first card plate 131. The first slot 110d corresponds to the first card plate 131 in size and position. When the terminal is inserted to a predetermined depth, the two are perfectly aligned.

[0088] In at least one embodiment of this application, the positioning part 121 has a first positioning surface 121c, the engaging protrusion 1212 has a first engaging surface 1212a, the first engaging surface 1212a is perpendicular to the first positioning surface 121c, and the locking block 111 has a second engaging surface 111a, the second engaging surface 111a is perpendicular to the first positioning surface 121c.

[0089] Please refer to Figures 1-8 In this embodiment, during the insertion stage, the isolator 120 is inserted into the housing 110 along the first direction A (insertion force direction), and the first positioning surface 121c on the positioning part 121 gradually approaches the inner stop surface of the housing 110 to complete the longitudinal positioning.

[0090] During the engagement stage, when the engagement protrusion 1212 is inserted into the area of ​​the engagement block 111, the first engagement surface 1212a and the second engagement surface 111a come into contact and engage, thereby completing the structural locking in the horizontal or lateral direction.

[0091] Since the first engaging surface 1212a and the first positioning surface 121c are perpendicular to each other, the entire structure forms a locking system with interfaces in three spatial directions, effectively preventing the isolator 120 from moving freely or loosening in the longitudinal, transverse and other directions.

[0092] By setting mutually perpendicular positioning surfaces and engaging surfaces, the isolation component 120 forms a stable structural fit similar to an "L-shape" or "boss-groove" after assembly, which restricts the insertion force in the direction, side and opposite directions, preventing any free shaking or falling off.

[0093] The multiple orthogonal facets in the structure work together to prevent the isolator 120 from loosening even under high-frequency vibration or pulling impact, thus improving the overall vibration resistance of the connector.

[0094] The first positioning surface 121c is provided on the positioning part 121 of the isolation member 120. It is a planar structure that serves as an assembly positioning reference. Usually, this surface is perpendicular to the insertion direction of the isolation member 120 (i.e., the first direction A) and serves as the end surface or stop surface of the assembly depth.

[0095] The first engaging surface 1212a is disposed on one side of the engaging protrusion 1212 and is a contact surface used to engage with the structure of the housing 110 engaging block 111. The first engaging surface 1212a is perpendicular to the first positioning surface 121c mentioned above, forming a spatial orthogonal geometric relationship.

[0096] The second engaging surface 111a formed on the housing 110 latch 111 is used to engage with the engaging protrusion 1212. This surface is also perpendicular to the first positioning surface 121c, ensuring that the entire mating system is orthogonal to each other in the assembly direction and locking direction.

[0097] In at least one embodiment of this application, the connector 100 with locking wire pair board further includes:

[0098] The outer shell 150 has a positioning cavity formed inside. The outer shell 110 and the isolation member 120 are both disposed in the positioning cavity and abut against the inner wall of the positioning cavity.

[0099] Please refer to Figures 1-8 In this embodiment, the isolator 120 and the housing 110 are first pre-assembled into one unit. At this time, the isolator 120 has been mechanically engaged with the housing 110, and the conductive terminal 130 and the connecting wire 140 are clamped, isolated and pressed and fixed. This component forms the core functional part of the connector and is a key structural unit for realizing electrical connection and mechanical fixation.

[0100] Then, the overall structure of the housing 110 and the isolator 120 is embedded into the positioning cavity provided inside the outer shell 150. In the positioning cavity, the overall structure forms a surface contact or point contact with the cavity wall, that is, the outer contours of the housing 110 and the isolator 120 are tightly restricted by the cavity.

[0101] The positioning cavity of the housing 150 provides structural constraints in both the direction of insertion force (axial) and the lateral direction (left and right, up and down). Whether it is the front and back force caused by the insertion and removal of the terminal, or the vibration and pulling in the external environment, this abutment structure can effectively prevent the housing 110 and the isolator 120 from undergoing micro-displacement or structural loosening within the connector.

[0102] The outer casing 150 provides a second layer of protection by adding a mechanical limiting barrier between the inner casing 110 and the isolation member 120. Combined with the structural guidance and enclosure restriction of the positioning cavity, it can effectively prevent the components from loosening or shifting due to long-term use or vibration.

[0103] The housing 150 also has a protective function, which can effectively isolate external dust, moisture, oil and other harmful media from entering the interior of the housing 110, making it particularly suitable for electrical connection scenarios that require waterproofing and dustproofing.

[0104] In at least one embodiment of this application, the outer shell 150 is provided with a second slot 150a, and the outer shell 110 is provided with an elastic plate 112, which engages with the second slot 150a.

[0105] Please refer to Figures 1-8In this embodiment, the housing 110 is inserted into the outer shell 150 along the axial direction during assembly. During the insertion process, the elastic locking plate 112 is constrained by the inner wall of the outer shell 150 and undergoes inward bending deformation. When the locking plate is aligned with the second locking groove 150a, it springs back under its own elastic force and accurately locks into the locking groove. After the locking is completed, the housing 110 is reliably locked in the outer shell 150 and cannot be pulled out or shaken.

[0106] The second slot 150a is located on the inner wall of the housing 150 and is a recessed structure used to receive the engaging structure from the housing 110. The position and size of the slot are preset and matched with the insertion path to achieve accurate alignment and accommodation.

[0107] The elastic plate 112 is disposed on the housing 110 and is a protruding structure with elastic deformation capability. During the assembly process, the elastic plate 112 can be temporarily pressed and rebounded during insertion to complete the "give way" and "pop out" actions. When the housing 110 is inserted to the predetermined depth, the elastic plate 112 automatically pops up and is embedded in the second slot 150a to form a locking and fixing.

[0108] By using the structural cooperation between the second card plate and the second card slot 150a, the axial and lateral movement of the housing 110 in the outer shell 150 can be effectively restricted, solving the problems of the housing 110 loosening, sliding or even falling off, and significantly improving structural safety.

[0109] The flexible locking structure has a certain buffering and shock absorption capacity, which can effectively absorb small deformation stress when the connector is subjected to micro-vibration, impact or temperature change, avoid hard impact on the structure, and improve the stability and reliability of long-term use.

[0110] In at least one embodiment of this application, the housing 150 has a through hole 150b, the through hole 150b is connected to the connecting hole 110a, and the conductive terminal 130 extends through the through hole 150b into the connecting hole 110a.

[0111] Please refer to Figures 1-8 In this embodiment, when the conductive terminal 130 enters from the outside, it first passes through the through hole 150b of the housing 150, and then continues to be inserted into the connecting hole 110a of the housing 110. During this process, the housing 150 and the housing 110 together guide, limit and protect the terminal, ensuring that its insertion direction is correct and the path is smooth.

[0112] By providing a through hole 150b and connecting it to the connecting hole 110a of the housing 110, a through insertion path is provided for the terminal, which can achieve precise guidance from the outside to the inside and reduce the risk of offset, jamming or incorrect insertion when the conductive terminal 130 is inserted.

[0113] The through hole 150b is provided on the outer shell 150 of the connector. It is a through hole that completely penetrates the outer shell 150. The position of the hole corresponds to the connecting hole 110a on the inner shell 110, forming a through structural link.

[0114] In at least one embodiment of this application, the housing 150 is provided with a protective block 151 protruding from it, and the conductive terminal 130 is located between two of the protective blocks 151.

[0115] Please refer to Figures 1-8 In this embodiment, the protective block 151 is part of the housing 150 and is designed as a structure that protrudes outward from the surface of the housing 150. It is usually arranged symmetrically as a pair. The two protective blocks 151 are located on both sides of the conductive terminal 130 and are arranged in a staggered or symmetrical manner to form a clamping or enclosure structure.

[0116] When the conductive terminal 130 protrudes from the housing 150, its exposed section (especially the plug-in end) is located in the gap between the two protective blocks 151. This space is usually slightly larger than the width of the terminal, which does not affect the plug-in function of the terminal, and plays a guiding and protective role in the structure.

[0117] During connector mating or external operation, if a tool collision or foreign object impact occurs, the external force is first absorbed or blocked by the protective block 151, thereby avoiding direct action on the conductive terminal 130. At the same time, a channel or slot is formed between the two protective blocks 151, which can guide the insertion direction and prevent incorrect insertion or deviation. The overall structure realizes the triple functions of mechanical protection, insertion guidance and spatial limitation.

[0118] The protective block 151 provided on the housing 150 can effectively prevent external impacts or misoperation from directly contacting the conductive terminal 130, reducing terminal deformation, breakage and other failures caused by accidental collisions.

[0119] The structural channel formed between the protective blocks 151 can guide the insertion direction in terms of physical structure, reduce the insertion angle deviation, and reduce the probability of misaligned insertion or failure to insert, thereby improving the ease of operation and positioning accuracy of connector insertion and removal.

[0120] Because the conductive terminal 130 has a more robust structure and a more balanced stress distribution, it avoids poor contact caused by terminal damage or displacement. The protective structure can also reduce the risk of micro-vibration interference at the contact points, which helps to improve the overall shock resistance of the connector.

[0121] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
