Description

[Technical Field]

[0001] This utility model relates to insulating housings, electrical connectors, and electrical connector assemblies, and in particular to an insulating housing, electrical connector, and electrical connector assembly that can increase the stability of the connection with the mating housing. [Background Technology]

[0002] Electrical connector assemblies generally include electrical connectors and mating connectors. Electrical connectors are typically electrical mating devices used to connect two active devices for the transmission of current or signals. Electrical connectors usually include an insulating housing and conductive terminals passing through the insulating housing. When the electrical connector is mated with a compatible mating connector, the conductive terminals become conductive with the terminals in the compatible mating connector to transmit current or signals.

[0003] Existing insulating shells typically include a main body, a locking structure, a protective structure, and a limiting structure. The locking structure is located on the first surface of the main body, and the protective structure is located on the upper surface of the main body. The protective structure and the first surface of the main body enclose the upper and lower sides of the locking structure. The protective structure generally has a draft channel running through the front-to-back direction. The limiting structure extends along the front-to-back direction and is located on the first surface of the main body, with the limiting structure and the protective structure spaced apart along the left-to-right direction. However, due to the spaced arrangement of the protective structure and the limiting structure, if the insulating shell is dropped during manufacturing and transportation, only the protective structure itself can bear all the impact force. Furthermore, the protective structure has a through channel running front-to-back, and its own strength is relatively poor, making it prone to damage. This means the protective structure cannot protect the locking structure, which is also prone to damage. Consequently, the connection between the insulating shell and the mating shell is unstable. Additionally, the limiting structure consists of only a single strip extending in the front-to-back direction. When the insulating shell and the mating shell are inserted, the end of the limiting structure extending in the front-to-back direction bears all the mating force, easily leading to damage of the limiting structure and thus causing instability in the connection between the insulating shell and the mating shell.

[0004] Therefore, it is necessary to design an insulating housing, electrical connector, and electrical connector assembly that can increase the stability of the connection with the mating housing in order to solve the above-mentioned technical problems. [Utility Model Content]

[0005] The purpose of this utility model is to connect one end of the limiting part to the protective structure and to set a channel between the limiting part and the protruding edge, thereby increasing the overall strength of the limiting structure and the protective structure, and thus realizing an insulating shell, electrical connector and electrical connector assembly that increases the stability of the connection with the mating shell.

[0024] An electrical connector, the electrical connector comprising an insulating housing and conductive terminals housed within the insulating housing;

[0025] The insulating shell includes a main body, a locking structure, a protective structure, a limiting structure, and a protruding edge. The locking structure is disposed on the first surface of the main body and is used to engage with the mating shell.

The first surface extends downward along the side edge in the left-right direction to form a second surface. The second surface is provided with a guide groove extending in the front-back direction.

[0026] A mating connector for mating with the electrical connector, the mating connector including a mating housing and mating terminals housed within the mating housing;

[0027] The docking housing has a docking cavity recessed along the front-to-back direction for inserting the insulating housing. The docking cavity has a first wall surface and second walls located on the left and right sides of the first wall surface. The first wall surface has a limiting groove for engaging with the limiting part for limiting. The width of the limiting groove along the left-to-right direction is greater than or equal to the sum of the widths of the limiting part and the reinforcing part along the left-to-right direction. The second wall surface has a protruding guide rib extending along the front-to-back direction. The guide rib engages with the guide groove for limiting. The width of the guide rib along the up-down direction is less than the sum of the widths of the limiting part and the reinforcing part along the left-to-right direction. The front side of the docking cavity has a retaining wall for retaining the docking terminal. The docking terminal passes through the retaining wall and enters the docking cavity to dock with the conductive terminal.

[0028] Furthermore, the inner wall surface of the retaining wall is provided with a stop portion, which is used to stop the insulating shell in the front-back direction. The retaining wall is provided with a terminal hole that runs through in the front-back direction. A positioning groove is provided recessed inward from the outer wall surface of the retaining wall and runs downward. The upper end of the positioning groove is connected to the terminal hole.

[0029] The docking terminal has a docking section and a bent section formed by bending downward from the docking section. When the docking section is inserted into the terminal hole near the lower end of the retaining wall, the bent section is confined within the terminal hole and the positioning groove and does not extend forward beyond the outer wall surface of the retaining wall.

[0030] Compared with the prior art, the insulating shell designed in this utility model has the following beneficial effects:

[0031] In this invention, the protective structure forms a through hole with the first surface, allowing the latching structure to pass through in the front-to-back direction. The protective structure restricts the latching structure's range of motion in the vertical and horizontal directions, ensuring that its upward range of motion does not exceed its elastic limit, thus preventing damage. Furthermore, when the insulating shell falls, the protective structure protects the latching structure from both vertical and horizontal directions, extending its service life. The limiting part extends in the front-to-back direction and cooperates with the docking shell for positioning. The rear end of the limiting part, near the latching structure in the horizontal direction, is integrally connected to the protective structure, allowing the limiting part and the protective structure to support each other, thereby strengthening their combined strength. This makes the protective structure less prone to damage, protecting the latching structure and improving the stability of the connection between the insulating shell and the docking shell. The limiting part is connected to the reinforcing part at its front end along the front-rear direction, increasing the stress-bearing area at the end of the limiting part. This avoids stress concentration at the end of the limiting part during mating with the docking shell, enhancing the strength of the limiting part and making its end less prone to damage. This improves the reliability of positioning when the insulating shell and the docking shell are mated. In injection molding of the insulating shell, a channel needs to be set in the front-rear direction of the reinforcing part to demold the insulating shell from the mold. In this design, the reinforcing part is set on the side of the limiting part away from the locking structure. Therefore, the channel for demolding is also set between the limiting part and the protrusion, eliminating the need to open a channel between the limiting part and the protective structure. This ensures a reliable connection between the limiting part and the protective structure, increasing the overall strength of the limiting structure and the protective structure, thereby increasing the stability of the connection between the insulating shell and the docking shell.

Detailed Implementation Methods

[0047] To better understand the content of this utility model, a more detailed description of this utility model will now be provided in conjunction with specific implementation schemes and illustrations.

[0048] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", "front", "back", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the indicated position or component must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0049] like Figures 1 to 12 As shown, the insulating shell, electrical connector, and electrical connector assembly of this utility model are defined in a vertical direction, which is the Z-axis, with the upward direction being the positive Z-axis direction, the front-back direction being the X-axis, the forward direction being the positive X-axis direction, the left-right direction being the Y-axis, and the rightward direction being the positive Y-axis direction. For ease of description, the vertical, left-right, and front-back directions in this utility model are relative positions and do not constitute a limitation on implementation.

[0050] like Figures 1 to 6 As shown, an electrical connector 1000 is used to mate with a mating connector 2000. The electrical connector 1000 includes an insulating housing 1 and conductive terminals 2 housed within the insulating housing 1. The insulating housing 1 protects the internal conductive terminals 2, which are used for electrical connection with mating terminals 4 inside the mating connector 2000 to ensure signal or current transmission. Preferably, the electrical connector 1000 further includes an insulating block embedded in the insulating housing 1 to limit the movement of the conductive terminals 2. The insulating housing 1 includes a main body 11, a locking structure 12, a protective structure 13, a limiting structure 14, and a protruding edge 16 partially protruding from the first surface of the main body 11. The main body 11 is used to allow the conductive terminal 2 to pass through and protect it. The locking structure 12 is used to engage with the mating connector 2000 to ensure the reliability of the connection between the electrical connector 1000 and the mating connector 2000. The limiting structure 14 cooperates with the mating housing 3 of the mating connector 2000 to limit the mating position between the mating connector 2000 and the electrical connector 1000. In this embodiment, the first surface is the upper surface. In other embodiments, the first surface can also be the left side surface, the right side surface, or the lower surface.

[0051] Please see Figures 1 to 4The main body 11 has a rectangular parallelepiped structure. The front left and right sides of the main body 11 have guide surfaces that slope outwards and backwards along the front end of the main body 11. These guide surfaces guide the connection between the insulating shell 1 and the docking shell 3, facilitating the insertion of the insulating shell 1 into the docking shell 3. The first surface of the main body is the upper surface, and a second surface (i.e., the left or right side surface) extends downwards along the left and right side edges of the first surface. The second surface has guide grooves 18 extending in the front-back direction. Specifically, the main body 11 has guide grooves 18 recessed inwards on the left and right side surfaces, extending in the front-back direction. The guide grooves 18 penetrate the front surface of the main body 11 and are used for the insertion of the guide ribs 35 of the docking shell 3. There are two guide grooves 18, which are recessed on the left and right side surfaces of the main body 11 respectively. These guide grooves ensure that the insulating shell 1 is inserted directly into the docking shell 3, preventing oblique or incorrect insertion. The main body 11 has terminal slots extending in the front-back direction, which are used to accommodate conductive terminals 2. The terminal slots are arranged in two rows, aligned vertically. Each row consists of multiple terminal slots extending horizontally. The main body 11 has recessed grooves on its left-right side surfaces, extending horizontally and penetrating the rear surface of the main body 11. These grooves are used to remove the insulating block embedded in the main body. There are two recessed grooves, one on each side of the main body 11, aligned horizontally. The lower surface of the main body 11 has an upwardly recessed mounting groove extending horizontally, used to embed and install the insulating block. The mounting groove communicates with the recessed groove, facilitating the removal of the insulating block through the groove. The mounting groove also communicates with the terminal slots. When the insulating block is embedded in the mounting groove, it limits the position of the terminal in the terminal slot.

[0052] like Figure 2 , Figure 3As shown, the locking structure 12 is disposed on the upper surface of the main body 11 and extends along the front-to-back direction. In the left-to-right direction, the locking structure 12 is located in the middle of the main body 11. The locking structure 12 includes a connecting part 121, an elastic part 122 connected to the connecting part 121, and a locking part 123 protruding above the elastic part 122. The connecting part 121 is connected and fixed to the main body 11. The elastic part 122 passes through the protective structure 13 along the front-to-back direction. The upper surface of the locking part 123 is inclined from the upper surface of the elastic part 122 to the rear and upward. The locking part 123 is used to engage with the docking housing 3. Specifically, there are two joints 121, spaced apart in the left-right direction. There are also two elastic parts 122, with their front ends connected to the two joints 121 respectively, and their rear ends connected to a fixing part located behind the protective structure 13. The fixing part is used to press and control the height of the elastic part 122 relative to the main body 11 in the up-down direction. In this embodiment, the joints 121 extend in the up-down direction, with their upper ends fixedly connected to the elastic parts 122 and their lower ends fixedly connected to the upper surface of the main body 11. The elastic parts 122 extend longitudinally in the front-back direction. In the up-down direction, there is a gap between the elastic part 122 and the upper surface of the main body 11, allowing the elastic part 122 to move relative to the main body 11 in both the up-down and left-right directions. By controlling the height of the gap between the elastic part 122 and the upper surface of the main body 11 in the up-down direction, the insertion and removal of the insulating shell 1 and the mating shell 3 can be achieved. The elastic portion 122 behind the locking portion 123 includes a horizontal area and a limiting area along the left direction. The horizontal areas of the two elastic portions 122 are close to each other to allow the limiting protrusion in the docking housing 3 to be inserted. The limiting areas of the two elastic portions 122 are set relatively far from the horizontal areas in the left-right direction to limit the range of left-right movement of the limiting protrusion in the docking housing 3. The fixing portion has a "T" shaped structure. The left and right ends of the fixing portion are respectively connected to the limiting areas of the two elastic portions 122. The lower end of the fixing portion is inserted between the gaps of the two elastic portions 122 and is respectively connected to the horizontal areas of the two elastic portions 122.

[0053] like Figures 2 to 4As shown, the protective structure 13 is disposed on the upper surface of the main body 11. The protective structure 13 and the upper surface together form a through hole 134 for the locking structure to pass through in the front-to-back direction, thereby protecting the latching structure 12 from impact damage in the vertical and horizontal directions and increasing the service life of the latching structure 12. The protective structure 13 extends in the horizontal direction, and its lower end is fixedly connected to the upper surface of the main body 11. In the horizontal direction, the protective structure 13 is located in the middle of the upper surface of the main body 11, and in the front-to-back direction, the protective structure 13 is close to the rear end of the main body 11. Specifically, the protective structure 13 and the upper surface of the main body 11 together form a through hole 134. The through hole 134 allows the elastic part 122 of the locking structure 12 to pass through in the front-back direction, thereby limiting the range of motion of the elastic part 122 of the locking structure 12 in the vertical and horizontal directions. It also ensures that the upward range of motion of the locking structure 12 does not exceed the elastic limit of the locking structure 12, thus preventing damage to the locking structure 12. Furthermore, it provides protection for the locking structure 12 in the vertical and horizontal directions. When the insulating shell 1 falls, the protective structure 13 can protect the locking structure 12 from the vertical and horizontal directions, thereby extending the service life of the locking structure 12. In this embodiment, the protective structure 13 includes a first protective section 131 and an extension section 133 arranged at intervals in the front-back direction, and a second protective section 132 connected between the first protective section 131 and the extension section 133. The first protective section 131 extends in the left-right direction and is plate-shaped. In the left-right direction, the first protective section 131 is centrally located on the upper surface of the main body 11. The left and right ends of the protective structure 13 are respectively connected to the two second protective sections 132. The middle of the first protective section 131 has a through hole 134 for the locking structure 12 to pass through. In the left-right direction, the through hole 134 is located in the middle of the first protective section 131. In the up-down direction, the through hole 134 extends to the upper surface of the main body 11. It has more space in the up-down direction, which is more conducive to pressing the locking structure 12 in the up-down direction to release it, and makes it easier to pull out the insulating shell 1 from the docking shell 3. The second protective section 132 is located on the upper surface of the main body 11. The height of the second protective section 132 in the vertical direction is equal to that of the first protective section 131 in the vertical direction. There are two second protective sections 132. The two second protective sections 132 extend obliquely from the left and right ends of the first protective section 131 away from the locking structure 12. The two second protective sections 132 can evenly distribute the load of the first protective section 131. Moreover, the obliquely arranged second protective sections 132 can absorb part of the impact load through their own deformation, thereby reducing the load of the first protective section 131 and the extension section 133 and improving the strength of the protective structure 13.The extension segment 133 extends in the left-right direction. The height of the extension segment 133 in the vertical direction gradually decreases from the second protective segment 132 towards the direction away from the second protective segment 132, thereby reducing the material required for manufacturing the insulating shell 1. The extension segment 133 is located behind the first protective segment 131 and at the rear end of the upper surface of the main body 11 in the front-rear direction. In the left-right direction, the end of the extension segment 133 closest to the first protective segment 131 connects to the second protective segment 132, and the end of the extension segment 133 away from the second protective segment 132 connects to the limiting part 141. This allows the force experienced by the insulating shell 1 when it docks with the mating shell 3 to be distributed along the extension segment 133 and the first protective segment 131 to different positions in the front-rear direction of the main body 11, preventing stress concentration in the first protective segment 131 when the insulating shell 1 falls or is impacted, thereby enhancing the strength of the entire protective structure 13. Specifically, two extension segments are provided, arranged in the left-right direction on both sides of the first protective segment 131, so that the impact load on both sides of the first protective segment 131 is evenly distributed. In other embodiments, the two second protection segments 132 extend vertically directly in the front-back direction.

[0054] like Figures 2 to 4 As shown, the limiting structure 14 is disposed on the first surface of the main body 11. The limiting structure 14 includes a limiting part 141 and a reinforcing part 142 for reinforcing the limiting part 141. The limiting part 141 extends forward from the protective structure 13 and has a longitudinal structure, which is used to cooperate with the docking shell 3 for limiting. Specifically, the rear end of the limiting part 141 is connected to the extension section 133 of the protective structure 13. The extension direction of the limiting part 141 is perpendicular to the extension direction of the protective structure 13, so that the limiting part 141 can provide support for the protective structure 13 in the front-to-back direction, thereby enhancing the strength of the protective structure 13, extending the service life of the protective structure 13, and the protective structure 13 can also provide lateral support for the limiting part 141, improving the strength of the limiting structure 14, thereby improving the stability of the connection between the insulating shell 1 and the docking shell 3. In this embodiment, there are two limiting parts 141, which are respectively connected to the two ends of the protective structure 13 in the left-right direction. The two limiting parts 141 ensure that the force on the protective structure 13 is evenly distributed between them, preventing the protective structure 13 from being damaged by excessive impact force and thus improving the overall strength of the protective structure. In other embodiments, there are multiple limiting parts 141, arranged side-by-side in the left-right direction, with the rear ends of each limiting part 141 connected to the protective structure 13. Specifically, there can be three, four, five, or six limiting parts 141.

[0055] like Figures 2 to 4As shown, the reinforcing part 142 is connected to the front end of the limiting part 141, protruding in the left-right direction on the side of the limiting part 141 away from the locking structure 12. In the front-back direction, the reinforcing part 142 is located at the front end of the upper surface of the main body 11. The reinforcing part 142 extends longitudinally in the left-right direction, dispersing the force borne by the front end of the limiting part 141 and preventing stress concentration at the front end of the limiting part 141 during engagement with the docking housing 3, thus enhancing the strength of the front end of the limiting part 141. In this embodiment, there are two reinforcing parts 142. The two reinforcing parts 142 are respectively connected to the front ends of the two limiting parts 141, and the two reinforcing parts 142 extend away from each other from the two limiting parts 141, respectively increasing the length of the front ends of the two limiting parts 141 in the left-right direction. This increases the force-bearing area of ​​the front ends of the two limiting parts 141, preventing stress concentration at the front ends of the limiting parts 141 during engagement with the docking housing 3, and enhancing the strength of the front ends of the two limiting parts 141. In other embodiments, there are multiple reinforcing portions 142, which are aligned along the front-to-back direction. Specifically, there may be three, four, five, or six reinforcing portions 142.

[0056] like Figures 2 to 4As shown, the insulating shell 1 also includes a reinforcing structure 15, which protrudes from the upper surface of the main body 11 and extends longitudinally in the front-back direction. The reinforcing structure 15 is connected between the joint 121 and the protective structure 13, so that the impact load borne by the locking structure 12 can be transferred to the protective structure 13 through the reinforcing structure 15, and then the protective structure 13 can disperse the load borne by the locking structure 12, thereby improving the stability of the connection position between the locking structure 12 and the main body 11. In this embodiment, the reinforcing structure 15 includes a first reinforcing block 151 and a second reinforcing block 152 connected to the front end of the first reinforcing block 151. The first reinforcing block 151 extends longitudinally in the front-back direction and is arranged on one side of the locking structure 12 in the left-right direction. The rear end of the first reinforcing block 151 is connected to the first protective section 131, which can apply a supporting force in the front-back direction to the protective structure 13. When the protective structure 13 is subjected to a thrust in the front-back direction, the protective structure 13 is less likely to tilt in the front-back direction, thereby improving the strength of the protective structure 13. The second reinforcing block 152 extends in the left-right direction and extends from the first reinforcing block 151 in the left-right direction to the joint 121, dispersing the stress borne by the joint 121 and improving the reliability of the connection between the locking structure 12 and the main body 11. Specifically, there are two reinforcing structures 15, located on the left and right sides of the locking structure 12, respectively. Two second reinforcing blocks 152 extend towards the locking structure 12 and connect to two joints 121 within the locking structure 12, thus dispersing the impact load on both joints 121 of the locking structure 12. In other embodiments, the reinforcing structure 15 extends longitudinally in the front-to-back direction and is located below the locking structure 12. The front end of the reinforcing structure 15 connects to the joint of the locking structure 12, and the rear end connects to the first protective section 131 of the protective structure 13.

[0057] like Figure 1 and Figure 4As shown, the protruding edge 16 is located at the edge of the rear end of the main body 11, so that the rear end of the main body 11 is surrounded and protected by the protruding edge 16, so as to prevent the insulation shell 1 from being damaged when it falls and to enhance the strength of the main body 11. The protruding edge 16 is at least partially provided on the upper surface of the main body 11 and is located on the side of the limiting part 141 away from the locking structure 12. A channel 17 is provided between the protruding edge 16 and the limiting part 141, so that the protrusion is fully exposed in the channel 17 in the front-back direction, which facilitates the mold core to be pulled out from the channel 17 when the insulation shell 1 is injection molded. The channel 17 is also correspondingly provided between the limiting part 141 and the protruding edge 16, ensuring a reliable connection between the limiting part 141 and the protective structure 13, thereby increasing the overall strength of the protective structure 13 and the limiting structure 14. In this embodiment, the protruding edge 16 includes a bottom edge strip 163, side edge strips 162 respectively disposed at both ends of the bottom edge strip 163, two top edge strips 161 respectively connected to the side edge strips 162 on both sides, and two guide strips 164 respectively connected to the two top edge strips 161. The bottom edge strip 163 is elongated and arranged along the left-right direction on the lower surface of the main body 11. The two side edge strips 162 extend from both ends of the bottom edge strip 163 along the up-down direction towards the upper surface of the main body 11. The two top edge strips 161 are both disposed on the upper surface of the main body 11, extending towards each other from the side edge strips 162 on both sides. The two top edge strips 161 are arranged opposite each other on both sides of the protective structure 13 in the left-right direction. The two top edge strips 161 are spaced apart corresponding to the limiting portions 141 on both sides of the protective structure 13 to form two channels 17. The two channels 17 correspond to the positions of the two protrusions in the front-back direction. Channel 17 extends along the front-to-back direction and also extends vertically away from the main body 11. During the manufacturing of the insulating shell 1, the dimensions of the mold core in the vertical direction are no longer restricted when it is inserted into channel 17 in the front-to-back direction. This prevents the mold core from being easily bent or broken during demolding, thus extending its service life. Guide strips 164 are arranged on the upper surface of the main body 11. These guide strips 164 are elongated strips extending from the top edge strip 161 in the front-to-back direction, serving as guides when docking with the mating shell 3. Two guide strips 164 are located on the left and right sides of the upper surface of the main body 11, respectively, guiding the insulating shell 1 from the left and right sides to prevent it from being inserted obliquely into the mating shell 3. The side surfaces of the guide strips 164 away from the protective structure 13 are flush with the side surfaces of the main body 11 in the left-to-right direction. The guide strips 164 further protect the left and right edges of the main body 11, preventing damage to the main body 11 if the insulating shell 1 falls.

[0058] like Figure 1 , Figure 5 , Figure 6As shown, the conductive terminal 2 extends in the front-to-back direction and is housed within the insulating housing 1 in the front-to-back direction. One end of the conductive terminal 2 is used to connect with the cable 5, and the other end of the conductive terminal 2 is used to mate with the mating terminal 4 of the mating connector 2000. The conductive terminal 2 includes a mating portion 21 and a crimping portion 23 located behind the mating portion 21. The mating portion 21 is used to mate with the mating terminal 4 of the mating connector 2000, and the crimping portion 23 is used to connect with the cable 5. The mating portion 21 has a cavity 22 extending in the front-to-back direction for the mating terminal 4 of the mating connector 2000 to be inserted. The cavity 22 has a first sidewall 211 and a second sidewall 212 on its left and right sides. The cavity 22 is provided with a contact spring 215 and a retaining spring 216 extending opposite to each other in the front-to-back direction. The contact spring 215 is used to contact the mating terminal 4, and the retaining spring 216 abuts against the lower part of the contact spring 215, making the connection between the contact spring 215 and the mating terminal 4 inserted into the cavity 22 more stable. The contact spring 215 and the abutment spring 216 are connected to the first sidewall 211 to facilitate bending during the manufacturing of the conductive terminal. An extension wall 213 extends from the front side of the second sidewall 212 towards the first sidewall 211. The extension wall 213 has a downwardly protruding anti-misplacement part 217 to prevent incorrect insertion of the conductive terminal 2 into the insulating housing 1. A stop wall 214 extends from the rear side of the second sidewall 212 towards the first sidewall 211, covering the area below the contact spring 215 and the abutment spring 216. Specifically, the abutment spring 216 is connected to the rear side of the first sidewall 211, and the contact spring 215 is connected to the front end of the first sidewall 211.

[0059] like Figures 7 to 12 As shown, an electrical connector assembly 10000 includes an electrical connector 1000 and a mating connector 2000 connected to the electrical connector 1000. In actual use of this embodiment, the insulating shell 1 of the electrical connector 1000 is inserted into the mating cavity 34 of the mating shell 3 of the mating connector 2000, and the conductive terminal 2 is mated and connected to the mating terminal 4 to achieve electrical conductivity. The mating connector 2000 includes a mating shell 3 and a mating terminal 4. The mating shell 3 is used to mate with the insulating shell 1, and the mating terminal 4 is housed within the mating shell 3. One end of the mating terminal 4 is used to connect to a circuit board (not shown in the figure), and the other end of the mating terminal 4 is used to mate with the conductive terminal 2 in the electrical connector 1000.

[0060] like Figures 11 to 12As shown, the mating housing 3 has a mating cavity 34 recessed along the front-rear direction. The mating cavity 34 is used for inserting the insulating housing 1. The front side of the mating cavity 34 has a retaining wall 31, the upper side of the mating cavity 34 has a first wall surface 32, and the left and right sides of the mating cavity 34 have second wall surfaces 33. The two second wall surfaces 33 are respectively connected to the left and right sides of the first wall surface 32. The retaining wall 31 is used to hold the mating terminal 4. The mating terminal 4 passes through the retaining wall 31 and enters the mating cavity 34 to mate with the conductive terminal 4. The inner wall surface of the retaining wall 31 is also provided with a stop portion 311 extending along the front-rear direction. The stop portion 311 is used to stop the insulating housing 1 along the front-rear direction. There are four stop portions 311, which are located at the four corners of the inner surface of the retaining wall 31. When the insulating housing 1 is inserted into the mating housing 3 from back to front, the four stop portions 311 stop on the front side of the insulating housing 1 to prevent the insulating housing 1 from being inserted too deeply. The retaining wall 31 has terminal holes 312 extending in the front-to-back direction, through which mating terminals 4 are inserted. Multiple terminal holes 312 are arranged in two rows, one above the other. Each row of terminal holes 312 extends in the left-to-right direction. A positioning groove 313 extending in the up-down direction is recessed from the outer wall surface of the retaining wall 31. The positioning groove 313 communicates with the terminal holes 312 near the lower end of the retaining wall 31, and is used to limit the mating terminals 4 inserted into the lower row of terminal holes. The first wall surface 32 has a limiting groove 321 for engaging with the limiting part 141. The width of the limiting groove 321 in the left-to-right direction is greater than or equal to the sum of the widths of the limiting part 141 and the reinforcing part 142 in the left-to-right direction. The second wall surface 33 has a protruding guide rib 35 extending in the front-to-back direction. The guide rib 35 engages with the guide groove 18 for limiting. The width of the guide rib 35 in the up-down direction is less than the sum of the widths of the limiting part and the reinforcing part in the left-to-right direction. The first wall surface 32 is also provided with a locking protrusion for engaging and limiting the locking part 123. When the insulating housing 1 and the docking housing 3 are docked, the locking protrusion engages and locks with the locking part 123. The second wall surface 33 extends forward to form two blocking walls. The two blocking walls are located on the left and right sides of the retaining wall 31 in the left and right directions. In the left and right directions, the blocking walls block the docking terminal 4 inserted into the terminal hole 312.

[0061] like Figure 9As shown, the mating terminal 4 includes a mating section 41 and a bent section 42 connected to the mating section 41, which is formed by bending downwards from the mating section 41. The mating section 41 is used to insert into the mating portion 21 of the conductive terminal 2, achieving electrical connection with the conductive terminal 2; the lower end of the bent section 42 is used to insert into the mounting hole (not shown in the figure) of the circuit board, achieving electrical connection with the circuit board. When the mating section 41 is inserted into the terminal hole 312 near the lower end of the retaining wall 31, the bent section 42 of the mating terminal 4 inserted into the lower row of terminal holes 312 is limited to the terminal groove and the positioning groove 313, and does not extend forward beyond the outer wall surface of the retaining wall 31, thereby reducing the area of ​​the circuit board occupied by the mating terminal 4 in the front-back direction, and also shortening the length of the mating terminal 4 inserted into the upper row of terminal holes 312 extending forward from the outer wall surface of the retaining wall, further reducing the area of ​​the circuit board occupied by the mating terminal 4 in the front-back direction.

[0062] In summary, the insulating shell 1 of this utility model has the following beneficial effects:

[0063] (1) In this utility model, the protective structure 13 forms a through hole 134 with the first surface for the locking structure 12 to pass through in the front-back direction. The protective structure 13 restricts the range of motion of the locking structure 12 in the up-down and left-right directions, ensuring that the upward range of the locking structure 12 does not exceed the elastic limit of the locking structure 12, thus avoiding damage to the locking structure 12. When the insulating shell 1 falls, the protective structure 13 can protect the locking structure 12 from the up-down and left-right directions, thereby extending the service life of the locking structure 12. The limiting part 141 extends in the front-back direction and cooperates with the docking shell 3 for limiting. The rear end of the limiting part 141 is integrally connected with the protective structure 13 on the side close to the locking structure 12 in the left-right direction, so that the limiting part 141 and the protective structure 13 support each other, thereby strengthening the strength of the limiting part 141 and the protective structure 13, making the protective structure 13 less prone to damage, protecting the locking structure 12, avoiding damage to the locking structure 12, and thus improving the stability of the connection between the insulating shell 1 and the docking shell 3. The front end of the limiting part 141 in the front-rear direction is connected to the reinforcing part 142, which increases the stress-bearing area at the end of the limiting part 141. This avoids stress concentration at the end of the limiting part 141 during the mating process with the docking housing 3, enhances the strength of the limiting part 141, and makes the end of the limiting part 141 less prone to damage, thereby improving the reliability of the positioning when the insulating housing 1 and the docking housing 3 are docked. When the insulating housing 1 is injection molded, in order to demold the insulating housing 1 from the mold, a channel 17 needs to be set in the front-rear direction of the reinforcing part 142. In this solution, the reinforcing part 142 is set on the side of the limiting part 141 away from the locking structure 12. Therefore, the channel 17 for demolding is also set between the limiting part 141 and the protrusion 16, without the need to open a channel 17 between the limiting part 141 and the protective structure 13. This ensures a reliable connection between the limiting part 141 and the protective structure 13, increases the overall strength of the limiting structure 141 and the protective structure 13, and thus increases the connection stability between the insulating housing 1 and the docking housing 3.

[0064] (2) The extension section 133 and the first protective section 131 are staggered in the front-rear direction, so that the force received by the insulating shell 1 when it docks with the docking shell 3 is distributed to different positions of the main body 11 along the extension section 133 and the first protective section 131, thereby improving the strength of the protective structure 13 and extending the service life of the protective structure 13; the extension section 133 and the second protective section 132 are arranged on both sides of the first protective section 131, so that the impact load on both sides of the first protective section 131 is evenly distributed, improving the strength of the protective structure 13, making the structure of the insulating shell 1 more stable, and making the conductive terminals 2 of the insulating shell 1 and the docking terminals 4 in the docking shell 3 more stable. A stable electrical connection is provided; and the second protection segment 132 is inclined from the first protection segment 131 and in a direction away from the locking structure 12. The inclined second protection segment 132 can also absorb a certain impact load through its own deformation, thereby reducing the load on the first protection segment 131 and the extension segment 133, which can further improve the strength of the protection structure 13. At the same time, the inclined second protection segment 132 makes the space formed by the second protection segment 132 and the first protection segment 131 larger, which is more ergonomic and makes it easier for the user to press the locking structure 12 located in the space formed by the second protection segment 132 and the first protection segment 131 to unlock.

[0065] (3) The front end of the first reinforcing block 151 of the reinforcing structure 15 is connected to the joint 121 of the locking structure 12, which can support the locking structure 12 from the left and right directions, improve the strength of the locking structure 12, and increase the overall width of the locking structure 12 in the left and right directions. When the insulating shell 1 and the mating shell 3 are mated, the force on the joint of the locking structure 12 can be distributed to the first reinforcing block 151 to avoid damage to the locking structure 12. The second reinforcing block 152 of the reinforcing structure 15 extends in the front and back direction and is perpendicular to the direction of extension of the first reinforcing block 151, which can support the locking structure 12 from the front and back directions. The first reinforcing block 151 is supported, increasing its strength. The rear end of the second reinforcing block 152 is connected to the protective structure 13. At the same time, the second reinforcing block 152 is perpendicular to the extension direction of the protective structure 13, which also provides a front-to-back supporting force to the protective structure 13, further improving its strength. When the insulating shell 1 and the docking shell 3 are docked, the reinforcing structure 15 can also disperse the force borne by the protective structure 13, preventing damage to the protective structure 13, thereby further increasing the stability of the connection between the insulating shell 1 and the docking shell 3.

[0066] (4) The bottom edge strip 163 and the two side edge strips 162 of the protruding edge 16 protect the rear end of the lower surface and side surface of the main body 11 respectively, preventing the main body 11 from being damaged when the insulating shell 1 falls, thereby enhancing the strength of the main body 11 and extending the service life of the insulating shell 1. The top edge strip 161 of the protruding edge 16 is arranged at intervals corresponding to the limiting parts 141 on both sides of the protective structure 13 to form two channels 17. The channels 17 extend in the vertical direction away from the main body 11. When manufacturing the insulating shell 1, the mold core is inserted into the channel 17 in the front-back direction, and the size of the mold core in the vertical direction is no longer restricted. When the mold core is pulled out from the channel 17 during demolding, it is not easy to be bent or broken, thereby extending the service life of the mold core. In addition, the top edge strip 161 extends in the left-right direction to provide support force in the left-right direction to the guide strip 164 connected to it, which can increase the strength of the guide strip 164, extend the service life of the guide strip 164, and further increase the stability of the connection between the insulating shell 1 and the docking shell 3.

[0067] (5) The contact spring 215 and the abutment spring 216 of the conductive terminal 2 are connected to the first side wall 211, which facilitates bending during manufacturing. The abutment spring 216 abuts against the lower part of the contact spring 215, making the connection between the contact spring 215 and the mating terminal 4 inserted into the cavity 22 more stable. An extension wall 213 extends from the front part of the second side wall 212 and a misalignment part 217 is provided to prevent the conductive terminal 2 from being inserted incorrectly when inserted into the insulating housing 1. When the insulating block is embedded in the terminal groove inside the insulating housing 1, When the terminal is limited, a stop wall 214 extends from the rear section of the second side wall 212 to block the contact spring 215 and the abutment spring 216 below. The stop wall 214 can prevent the insulating block from damaging the contact spring 215 and the abutment spring 216, thereby extending the service life of the conductive terminal 2. At the same time, when the conductive terminal 2 is not inserted into the position, the stop wall 214 prevents the insulating block from being assembled into the position, so as to avoid affecting the docking of the contact spring 215 of the conductive terminal 2 with the docking terminal 4.

[0068] (6) The docking cavity 34 of the docking housing 3 allows the insulating housing 1 to be inserted. The first wall surface 32 of the docking cavity 34 is provided with a limiting groove 321, which can cooperate with the limiting part 141 of the insulating housing 1 to limit the position, so that the docking housing 3 and the insulating housing 1 are not easy to shake up and down when docking, thereby maintaining a stable connection between the docking housing 3 and the insulating housing 1 from the vertical direction. The second surface of the insulating housing 1 is provided with a guide groove 18 in the front-back direction. The second wall surface 33 of the docking housing 3 is provided with a guide rib 35 extending in the front-back direction. The guide rib 35 can cooperate with the guide groove 18 to limit the position, so that the docking housing 3 and the insulating housing 1 can dock. It is not easy to sway left and right, thereby improving the stability of the connection between the insulating shell 1 and the docking shell 3 from the left and right directions. Moreover, the width of the guide rib 35 in the vertical direction is less than the sum of the widths of the limiting part 141 and the reinforcing part 142 in the horizontal direction. The combination of the limiting part 141 and the reinforcing part 142 in this solution makes the width of the front end of the limiting part 141 wider than the width of the general guide rib 35. During the process of the insulating shell 1 and the docking shell 3, the force-bearing area at the end of the limiting part 141 is larger than the force-bearing area of ​​the guide rib 35, which can avoid stress concentration at the end of the limiting part 141, thereby enhancing the strength of the limiting part 141.

[0069] (7) The retaining wall 31 of the docking housing 3 is recessed inward and extends downward through a positioning groove 313. The upper end of the positioning groove 313 is connected to the terminal hole 312, so that the bent section 42 of the docking terminal 4 inserted into the terminal hole 312 near the lower end of the retaining wall 31 is limited in the terminal groove and the limiting groove 321, avoiding the docking terminal 4 from shifting left and right, and making it easy for the docking terminal 4 to be accurately inserted into the circuit board below. The bent section 42 does not extend forward beyond the outer wall surface of the retaining wall 31, so that the docking terminal 4 is close to the retaining wall 31 in the front-back direction, thereby reducing the area of ​​the circuit board occupied by the docking terminal 4 in the front-back direction.

[0070] The above detailed description is only a description of the preferred embodiment of this utility model and is not intended to limit the patent scope of this utility model. Therefore, all equivalent technical changes made using the content of this invention's specification and illustrations are included within the patent scope of this invention.
