Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a bent connector socket. Background Technology

[0002] With the rapid development of new energy vehicles, the number and complexity of electronic and electrical equipment have increased significantly. Electronic components in new energy vehicles, such as motors, battery management systems, and on-board chargers, generate electromagnetic interference during operation. Ensuring the normal operation of these electronic systems requires a high level of electromagnetic environmental control; poor electromagnetic compatibility can lead to malfunctions, communication interruptions, or data errors. Connectors are crucial electronic devices in new energy vehicles. Chinese invention patent application CN118232066A discloses a bent high-voltage connector socket. This socket includes a socket housing and a front insulator assembly and a rear insulator assembly installed within the housing. The socket housing is a plastic insulating shell. The front and rear insulator assemblies are fitted inside the housing. The front insulator assembly includes a front insulator and a front shield, with the front shield fitted over the front insulator. The rear insulator assembly includes a rear insulator and a rear shield, with the rear shield fitted over the rear insulator. The shielding structure uses a front and rear shield overlap method, which not only makes the assembly process cumbersome but also results in fewer shielding contacts at the overlap, with some overlap edges lacking shielding contacts altogether, failing to achieve 360° shielding contact, and leaving gaps at the overlap, leading to poor shielding performance.

[0003] Chinese utility model patent CN216121011U discloses a novel connector, which is a bent connector. It includes a metal shell, a base (i.e., a front insulator) fixedly installed in the inner cavity of one end of the metal shell, and a shielding shell fixedly fitted outside the base, contacting the metal shell. Signal pins and power pins are fixedly installed inside the base. A plug assembly (i.e., a rear insulator) is fixedly installed in the inner cavity of the other end of the metal shell, with a signal socket and a power socket fixed inside the plug assembly. The signal pins and power pins are respectively inserted into the signal socket and power socket. The front end of the shielding shell is rolled outwards with several flanges, each flange abutting against the inner wall of the metal shell, thus providing shielding contact between the shielding shell and the metal shell. This provides dual shielding, which, compared to the aforementioned front and rear shielding overlap method, can improve shielding performance to a certain extent. However, the connector has a problem: the rear insulator has a snap-fit ​​structure at its rear end, and the metal shell has a corresponding snap-fit ​​hole. The rear insulator is fixed inside the metal shell by the snap-fit ​​structure engaging with the snap-fit ​​hole. This snap-fit ​​structure is a cantilever snap-fit, including a cantilever arm that extends rearward along the axial direction of the rear insulator and a snap-fit ​​on the cantilever arm. The snap-fit ​​engages with the snap-fit ​​hole on the metal shell, and the cantilever arm extends outside the metal shell. When the rear insulator needs to be removed, the cantilever arm can be pressed inward to remove the rear insulator from the socket housing. Since the snap-fit ​​structure protrudes outside the metal shell, after the connector is fixed on the device panel, the flange face of the metal shell is sealed with the device panel, the rear end of the rear insulator passes through the mounting hole on the device panel, and the cantilever arm of the snap-fit ​​structure at the rear end of the rear insulator extends outside the mounting hole on the device panel. However, the vehicle experiences significant vibration and impact during operation, so the snap-fit ​​structure is easily disengaged from the snap-fit ​​hole on the metal shell due to vibration, impact, or other forces, resulting in the failure to fix the rear insulator and the problem of the rear insulator falling off. Utility Model Content

[0004] The purpose of this invention is to provide a bent connector socket to solve the problem of poor reliability of the connector due to the poor fixation reliability of the rear insulator in existing bent connectors.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bent connector socket includes a socket housing, a rear insulator is inserted and fixed in the inner cavity of one end of the socket housing, the rear insulator is provided with barbs, the socket housing is provided with a rear insulator limiting groove, the barbs of the rear insulator are inserted into the rear insulator limiting groove to fix the rear insulator in the socket housing, and the rear insulator is also provided with a secondary fixing structure for cooperating with the device panel to fix the rear insulator.

[0007] Furthermore, a secondary limiting boss is provided on the outer surface of the rear insulator. The secondary limiting boss is used to press against the equipment panel and engage with the equipment panel for limiting. The secondary limiting boss constitutes the secondary fixing structure of the rear insulator.

[0008] Furthermore, the secondary limiting boss is in the shape of an "I". The two parallel sides of the "I"-shaped secondary limiting boss are arranged at intervals along the axial direction of the rear insulator. The side of the two parallel sides closer to the rear end of the rear insulator is used to press against the equipment panel and cooperate with the limiting mechanism of the equipment panel.

[0009] Furthermore, a boss receiving groove is provided on the rear inner wall of the socket housing, and the secondary limiting boss is received in the boss receiving groove.

[0010] Furthermore, the inner wall of the socket housing is provided with a rear insulator barb avoidance groove extending along the rear insulator insertion direction, so as to avoid the rear insulator barb during the rear insulator insertion process.

[0011] Furthermore, the socket housing is provided with a rear insulator mounting anti-misalignment groove, and the rear insulator is provided with an anti-misalignment protrusion. The anti-misalignment protrusion cooperates with the rear insulator mounting anti-misalignment groove to realize the rear insulator being inserted into the socket housing in an anti-misalignment manner.

[0012] Furthermore, a front insulator assembly is inserted and fixed in the inner cavity of the other end of the socket housing. The front insulator assembly includes a front insulator and a shielding shell fixedly fitted outside the front insulator. The front insulator is provided with a rearwardly extending front insulator positioning claw. The extended end of the front insulator positioning claw has a forward-facing hook. The socket housing is provided with a front insulator positioning stop. The front insulator positioning claw hooks onto the front insulator positioning stop to fix the front insulator assembly inside the socket housing.

[0013] Furthermore, the shielding shell is a rectangular shell with a spring claw contact on the long side and a convex contact on the short side. The socket shell is a metal shell, and the shielding shell makes shielding contact with the socket shell through the spring claw contact and the convex contact.

[0014] Furthermore, the front insulator has a guide ramp at its front end for guiding the assembly of the shielding shell onto the front insulator.

[0015] Furthermore, signal pins and power pins are fixed inside the front insulator, and a front insulator assembly guide groove is provided inside the socket housing to guide the front insulator into the socket housing in a direction that is guided and engaged with the signal pins and power pins along the insertion direction.

[0016] Beneficial Effects: This utility model of a bent connector socket is an improved invention. By providing barbs on the rear insulator and a limiting groove inside the socket housing, the barbs and the limiting groove engage to fix the rear insulator within the socket housing, achieving primary fixation. Since the barbs are hidden within the socket housing cavity and not exposed, they effectively prevent the barbs from dislodging from the limiting groove due to vibration, impact, or other forces, ensuring the reliability of the primary fixation. Simultaneously, a secondary fixing structure is provided on the rear insulator. This secondary fixing structure, in conjunction with the device panel's limiting mechanism, provides secondary fixation of the rear insulator. This secondary fixation further ensures the reliability of the rear insulator's fixation, thereby guaranteeing the reliability of the connector's use. Attached Figure Description

[0028] In existing bent connectors, the rear insulator is fixed inside the metal housing via a cantilevered snap-fit ​​structure that engages with a locking hole on the metal housing. This cantilevered snap-fit ​​structure protrudes from the metal housing, making it prone to detachment due to vibration, impact, or other stresses. This leads to instability in the rear insulator's fixation and potential detachment. To address this, this invention proposes a bent connector socket that improves the reliability of the rear insulator's fixation. The basic inventive concept involves simultaneously incorporating a primary fixation structure and a secondary fixation structure on the rear insulator. The primary fixation structure uses barbs that engage with a limiting groove inside the socket housing to secure the rear insulator. After the connector socket is mounted onto the device panel, the secondary fixation structure engages with the panel to further secure the rear insulator. This dual fixation improves the reliability of the rear insulator's fixation.

[0029] Based on the above inventive concept, the embodiments of this utility model are described in detail below.

[0030] like Figure 1As shown, the bendable connector socket of this utility model includes a socket housing 1, which has a 90° bend. A front insulator assembly is inserted and fixed in the inner cavity of one end of the socket housing 1. The front insulator assembly includes a front insulator 2 and a shielding shell 3 fixedly fitted outside the front insulator 2. A signal pin 4 and a power pin 5 are fixed inside the front insulator 2. A rear insulator 7 is inserted and fixed in the inner cavity of the other end of the socket housing 1. A signal jack terminal 8 and a power jack terminal 9 are fixed inside the rear insulator 7. A signal sealing plug 13 is provided on the signal jack terminal 8. The signal pin 4 is inserted into the signal jack terminal 8, and the power pin 5 is inserted into the power jack terminal 9. After the terminals of the signal jack terminal 8 and the power jack terminal 9 are wired, the anti-skewing upper buckle 10 and the anti-skewing lower buckle 11 cooperate to lock the cable and prevent the cable from skewing. The rear end of the socket housing 1 has a flange portion 1-1, on which bolt mounting holes are provided for fixing the connector socket to the device panel 12 (see...). Figure 10 The rear end face of the flange 1-1 is provided with a mounting groove, and a sealing ring 6 is installed in the mounting groove to achieve a sealed fit between the connector socket and the equipment panel 12.

[0031] like Figure 2-3 As shown, the front insulator 2 is a plastic shell, and the signal pin 4, power pin 5, and front insulator 2 are injection molded into one piece, resulting in a compact structure and increased bonding strength between the signal pin 4, power pin 5, and front insulator 2. The signal pin 4 and power pin 5 are generally L-shaped, with their horizontal sides accommodated in corresponding recesses in the front insulator 2, and their vertical sides extending outside the front insulator 2. The front insulator 2 is provided with two rearwardly extending front insulator positioning claws 2-1, spaced apart across the width of the front insulator 2. The extended ends of the front insulator positioning claws 2-1 have forward-facing hooks 2-2. A claw deformation space 2-3 is reserved inside the front insulator positioning claws 2-1, and a claw deformation avoidance chamfer 2-4 is provided behind the claw deformation space 2-3 to provide sufficient space for the front insulator positioning claws 2-1 to deform under pressure. The front insulator positioning claw 2-1 is used to engage with the front insulator positioning stop 1-2 inside the socket housing 1 (see... Figure 8 The front insulator assembly is secured to the socket housing 1 in conjunction with the insulator assembly to prevent it from detaching.

[0032] Symmetrical shielding shell limiting steps 2-5 are provided on the left and right sides of the front insulator 2. The shielding shell 3 is assembled onto the front insulator 2 from the front end. The shielding shell 3 is blocked from moving forward by the shielding shell limiting steps 2-5, thus limiting the forward movement of the shielding shell 3. Symmetrical shielding shell positioning grooves 2-6 are provided on the upper and lower sides of the front insulator 2. The shielding shell positioning grooves 2-6 are used to engage with the shielding shell positioning claws 3-1 on the shielding shell 3 (see... Figure 4The shielding shell 3 is positioned rearward to prevent it from detaching from the front insulator 2. The shielding shell 3 is assembled onto the front insulator 2 from its front end. Therefore, a guide ramp 2-7 is provided at the front end of the front insulator 2 to guide the assembly of the shielding shell 3 onto the front insulator 2. The guide ramp 2-7 facilitates rapid assembly of the shielding shell 3, improving assembly efficiency. The assembly process involves no forced installation structures, ensuring convenient assembly without deformation or burrs.

[0033] like Figure 4 As shown, the shielding shell 3 is a rectangular shell. Symmetrically arranged on the upper and lower sides of the shielding shell 3 are shielding shell positioning claws 3-1 extending inwards from front to back. The shielding shell positioning claws 3-1 engage with the shielding shell positioning grooves 2-6 on the front insulator 2 to limit the rearward movement of the shielding shell 3 on the front insulator 2, preventing the shielding shell 3 from detaching from the front insulator 2. The rear end of the shielding shell 3 is rolled inwards with a rolled edge structure 3-4, and the front end of the front insulator 2 is secured within the rolled edge structure 3-4. Multiple rearwardly extending claw contacts 3-2 are evenly distributed on the upper and lower sides of the shielding shell 3, with the claw contacts 3-2 on the same side spaced apart. Two convex contacts 3-3 are respectively provided on the left and right sides of the shielding shell 3, with the two convex contacts 3-3 on the same side spaced apart. (See diagram below.) Figure 5-6 As shown, the socket housing 1 is a metal housing, and the shielding shell 3 achieves shielding contact with the socket housing 1 through various spring-loaded contacts 3-2 and raised contacts 3-3, providing dual shielding performance. Multiple spring-loaded contacts 3-2 are evenly distributed along the long side of the shielding shell 3 to achieve shielding contact; the spring-loaded contact reduces assembly force and facilitates assembly. The short side is smaller, therefore multiple raised contacts 3-3 are provided on the short side to achieve shielding contact and ensure shielding performance. Two to four contacts are provided on each side of the shielding shell 3 to contact the socket housing 1, thus achieving 360° shielding contact, minimizing gaps, and the metal shell is located outside the gaps, providing dual shielding and significantly improving the product's shielding performance.

[0034] It should be noted that the number of spring-loaded contacts 3-2 and convex contacts 3-3 on each side of the shielding shell 3 is unlimited and can be flexibly adjusted according to the size of the shielding shell 3. Furthermore, in the above embodiment, the shielding shell 3 makes shielding contact with the socket housing 1 through multiple spring-loaded contacts 3-2 and convex contacts 3-3. This is partly due to the size of each side of the shielding shell 3, which determines whether to use spring-loaded contacts 3-2 or convex contacts 3-3, and partly to minimize assembly force. Of course, in other embodiments, spring-loaded contacts 3-2 can be provided on each side of the shielding shell 3 to achieve shielding contact; or convex contacts 3-3 can be provided on each side of the shielding shell 3 to achieve shielding contact. In this case, the assembly force is larger, and assembly is relatively more difficult.

[0035] The internal structure of socket housing 1 can be referenced. Figure 7-8 .like Figure 8As shown, the socket housing 1 has a front insulator positioning stop 1-2 inside. When the front insulator assembly is inserted into the socket housing 1, the hook part 2-2 of the front insulator positioning claw 2-1 passes over the front insulator positioning stop 1-2 and hooks onto the front insulator positioning stop 1-2. The rear end of the front insulator 2 abuts against the socket housing 1, thereby preventing the front insulator 2 from detaching and fixing it inside the socket housing 1, thus achieving primary fixation of the front insulator 2. After the rear insulator 7 is assembled, the signal pin 4 and power pin 5 fixed inside the front insulator 2 are inserted into the signal socket terminal 8 and power socket terminal 9 of the rear insulator 7, respectively, thus achieving secondary fixation of the front insulator 2.

[0036] like Figure 8 As shown, the socket housing 1 has a rear insulator limiting groove 1-3 inside, which is used to fix the rear insulator 7 inside the socket housing 1. Figure 9 As shown, symmetrical barbs 7-1 are provided on the two opposite outer surfaces of the rear insulator 7. After the rear insulator 7 is inserted, the barbs 7-1 engage with the rear insulator limiting grooves 1-3, thus securing the rear insulator 7 to the socket housing 1 and achieving primary fixation of the rear insulator 7. Since the barbs 7-1 are hidden within the inner cavity of the socket housing 1 and are not exposed, they can effectively prevent the barbs 7-1 from dislodging from the rear insulator limiting grooves 1-3 due to vibration, impact, or other forces, ensuring the reliability of the primary fixation. The rear insulator 7 is also provided with a secondary fixation structure for cooperating with the device panel 12 to perform secondary fixation of the rear insulator 7. Specifically, secondary limiting protrusions 7-2 are symmetrically provided on the two opposite outer surfaces of the rear insulator 7, such as... Figure 10 As shown, after the connector is installed on the device panel 12, the secondary limiting boss 7-2 presses against the device panel 12. The device panel 12 limits the secondary limiting boss 7-2 from the rear, thereby achieving secondary fixation of the rear insulator 7. The secondary limiting boss 7-2 constitutes a secondary fixing structure for the rear insulator. Through these two fixations, the fixing reliability of the rear insulator 7 is greatly improved.

[0037] The secondary limiting boss 7-2 is I-shaped. Its two parallel edges are spaced apart along the axial direction of the rear insulator 7. The edge closer to the rear end of the rear insulator 7 is used to press against the equipment panel 12 for a limiting engagement. The I-shape of the secondary limiting boss 7-2 ensures high structural strength and the ability to withstand certain compressive forces, thus guaranteeing the reliability of the secondary fixation of the rear insulator 7. In other embodiments, the secondary limiting boss 7-2 can also be rectangular, square, trapezoidal, or other structures, as long as a reliable limiting engagement between the secondary limiting boss 7-2 and the equipment panel 12 is ensured. In other embodiments, the secondary limiting boss 7-2 may not be provided on the outer surface of the rear insulator 7. Instead, a rearward-facing limiting step surface can be formed on the outer surface of the rear insulator 7. This limiting step surface engages with the equipment panel 12 to achieve secondary fixation of the rear insulator 7. In this case, the rearward-facing limiting step surface constitutes the secondary fixation structure of the rear insulator.

[0038] like Figure 7 As shown, a boss receiving groove 1-4 is provided on the inner wall of the rear end of the socket housing 1. The secondary limiting boss 7-2 on the rear insulator 7 is accommodated in the boss receiving groove 1-4. This arrangement helps to reduce the volume of the socket housing 1. A rear insulator barb avoidance groove 1-5 extending along the insertion direction of the rear insulator 7 is also provided on the inner wall of the socket housing 1 to avoid the rear insulator barb 7-1 during the insertion of the rear insulator 7, thus preventing the rear insulator barb 7-1 from continuously interfering with the inner wall of the socket housing 1 and generating strong friction, which could lead to burrs. The front wall of the rear insulator barb avoidance groove 1-5 is inclined to ensure that the rear insulator barb 7-1 can pass smoothly. Of course, in other embodiments, the rear insulator barb avoidance groove 1-5 may not be provided in the socket housing 1. Of course, the rear insulator barb 7-1 can also be an elastic barb. In this case, it is not necessary to set the rear insulator barb relief groove 1-5 in the socket housing 1. The rear insulator barb 7-1 is inserted with a slight interference fit with the inner wall of the socket housing 1, which can also ensure a small insertion force. The friction between the rear insulator barb 7-1 and the inner wall of the socket housing 1 is also relatively light.

[0039] like Figure 7 As shown, the socket housing 1 is provided with a rear insulator mounting anti-misalignment groove 1-6, which is used to engage with the anti-misalignment protrusion 7-3 on the rear insulator 7 (see...). Figure 9 This, in conjunction with other components, enables the rear insulator 7 to be assembled correctly to prevent misalignment of the socket housing 1. For example... Figure 8As shown, the socket housing 1 has a front insulator assembly guide groove 1-7 inside. There are three front insulator assembly guide grooves 1-7 in total. The two grooves on both sides guide and cooperate with the two power pins 5 along the insertion direction, and the middle groove guides and cooperates with the two signal pins 4 along the insertion direction, thereby guiding and preventing the front insulator 2 from being assembled into the socket housing 1.

The patent protection scope of the present utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present utility model shall also be included within the protection scope of the present utility model.
