Description

Technical Field

[0001] The present patent application relates to electrical connection technology, and more particularly to a lever-type electrical connector with a novel resilient CPA. Background Art

[0002] Lever type electrical connectors are widely used in the field of electrical and electronic architecture (EEA) of vehicles and various industrial connection fields.

[0003] A typical lever-type electrical connector generally includes a plastic housing for accommodating terminals and an operating lever mounted on the plastic housing. Figure 1A is a schematic diagram of the existing lever-type electrical connector 100 and the matching CPA device 160. Figure 1B show Figure 1A The lever of the lever-type electrical connector 100 is shown in a released state. Figure 1C show Figure 1A The lever locking state of the lever type electrical connector 100 is shown. Figure 1D show Figure 1A A cross-sectional view of a lever-type electrical connector 100 in a locked state is shown.

[0004] like Figure 1A The exemplary lever-type electrical connector 100 shown includes an upper cover 110 and a terminal housing 120 assembled therewith at the lower part. The terminal housing 120 is provided with pivots 122 on both sides. The two arms of a U-shaped operating lever 130 are sleeved and mounted on the pivots 122. The crossbar connected between the two arms of the operating lever is provided for the user to grasp and pivot. The two arms of the operating lever 130 are also provided with cam grooves 133, which can receive the cam shaft on the mating connector (not shown), so that the relative distance between the lever-type electrical connector 100 and the mating connector can be adjusted by rotating the operating lever 130.

[0005] More specifically, the operating lever 130 can be pivotally switched between a lever release position and a lever locking position: in the lever locking position (i.e. Figure 1C The lever 130 can bring the lever connector 100 and the mating connector (not shown) into close relative positions, thereby achieving stable insertion of the two; in the release position (i.e. Figure 1B ), the lever 130 can cause the lever connector 100 to retreat relative to the mating connector, thereby facilitating the separation of the two.

[0006] like Figure 1AThe cover 110 shown is installed at the wire entry end of the terminal plastic shell 120, and is provided with a wire entry port on one side, so as to achieve 90-degree wire entry. A locking structure 115 is provided on the cover 110, and a corresponding clamping portion 135 is provided on the crossbar of the U-shaped operating lever 130. The locking structure 115 may include a locking arm 1151 in the form of a cantilever beam, and a clamping protrusion 1152 is provided at the free end of the locking arm 1151. When the operating lever 130 is placed in the locked position, the clamping portion 135 on the crossbar of the operating lever 130 will be clamped with the locking structure 115 on the cover 110. Specifically, the clamping portion 135 on the crossbar and the clamping protrusion 1152 form a physical interference, preventing the crossbar from rotating clockwise to leave the locked position.

[0007] In order to enhance the stability of this locking, a secondary locking structure, specifically a CPA device 160, can be used. Figure 1B As shown in FIG. 1D , the CPA device 160 is slidably mounted in the locking structure 115 on the housing 110, which can first be pushed to Figure 1B —1D shows the pre-locking position. The CPA device 160 in the pre-locking position relies on the snap-fitting protrusions 162 at the ends of the elastic arms 161 on both sides. Under the action of a larger force, the CPA device 160 can overcome the interference resistance of the snap-fitting protrusions 162 and the snap-fitting protrusions 163 and be pushed further to the left to the final locking position. The CPA device 160 in the final locking position will physically interfere with the locking structure 115, especially preventing the locking arm 1151 of the locking structure 115 from being bent and deformed downward, thereby preventing the locking structure 115 of the housing 110 from releasing the snap-fitting portion 135 of the crossbar.

[0008] It can be understood that the above-mentioned CPA device 160 essentially obtains the locking force by means of the cantilever beam structure of the elastic arm 161. In other implementations, the CPA device can obtain the locking force by a transversely arranged simply supported beam device.

[0009] Whether locking with a cantilever beam structure or a simply supported beam structure, it essentially relies on the clamping of the elastic arm structure. However, in many practical applications, especially in miniaturized development scenarios, the plastic elastic arm is prone to deformation or breakage, resulting in low stability of the connector product, and even difficult to meet the development requirements of the locking force proposed by downstream manufacturers (such as OEM manufacturers) (for example, the GM 3191 standard proposes a force requirement of 110N min). Summary of the invention

[0010] According to one aspect of the present application, a lever-type electrical connector is proposed, comprising: a terminal shell for accommodating a terminal; a connector cover shell for being installed on the incoming line end of the terminal shell, the side of the connector cover shell being provided with an arc guide rail; an operating lever for being pivotally installed on the terminal shell; and a CPA device, the CPA device being constructed to be installed on the transverse connecting portion of the operating lever, the CPA device comprising a main body and a locking arm extending from the side of the main body, the CPA device also comprising an elastic structure arranged at or formed at the front end of the main body, wherein after the CPA device is installed on the operating lever, when the elastic structure is not deformed, the end of the locking arm is located at a first position, at which time the pivotal movement of the operating lever is interfered by the arc guide rail, and when the elastic structure contracts and deforms, the end of the locking arm moves to a second position, at which time the pivotal movement of the operating lever is not interfered by the arc guide rail.

[0011] According to the scheme of the lever-type electrical connector of the present application, as an optional implementation method, sliders are provided at both ends of the body of the CPA device, and the CPA device is installed in the corresponding installation grooves on the joystick through the sliders at both ends.

[0012] In the solution of the lever-type electrical connector according to the present application, as an optional implementation, the mounting groove is arc-shaped.

[0013] In the lever-type electrical connector solution of the present application, as an optional implementation, the arc-shaped mounting slot is used to convert the forward and backward movement of the body of the CPA device into the up and down movement of the end of the locking arm.

[0014] In the solution of the lever-type electrical connector according to the present application, as an optional implementation, the elastic structure is an elastic ring structure formed at the front end of the body of the CPA device.

[0015] In the solution of the lever-type electrical connector according to the present application, as an optional implementation, the elastic structure is a spring provided at the front end of the body of the CPA device.

[0016] In the scheme of the lever-type electrical connector according to the present application, as an optional implementation method, the locking arm of the CPA device extends from the sliders at both ends of the CPA device, and the extension direction of the locking arm is not coplanar with the body but forms an angle, and the angle is selected so that when the CPA device is installed on the joystick, the extension direction of the far end of the locking arm is basically consistent with the extension direction of the left arm and the right arm of the joystick.

[0017] In the solution of the lever-type electrical connector according to the present application, as an optional implementation, a locking block is provided at the end of the locking arm.

[0018] In the scheme of the lever-type electrical connector according to the present application, as an optional implementation method, a notch opening inward is provided at the distal end of the locking arm of the CPA device and at the connection with the locking block, and the size of the notch is constructed to be able to accommodate the arc-shaped guide rail on the terminal plastic shell.

[0019] In the scheme of the lever-type electrical connector according to the present application, as an optional implementation method, when the CPA device is installed into the operating lever, the elastic structure can be deformed by applying a force to the CPA device, so that the body of the CPA device can be further pushed in along the installation groove, causing the position of the locking block at the end of the locking arm on the side of the body to drop.

[0020] In the scheme of the lever-type electrical connector according to the present application, as an optional implementation method, when the force applied to the CPA device is released, the elastic structure rebounds, and its rebound force will cause the main body of the CPA device to retreat along the mounting groove and cause the position of the locking block at the end of the locking arm on the side of the main body to rise again.

[0021] In the scheme of the lever-type electrical connector according to the present application, as an optional implementation, when the elastic structure contracts and deforms, the end of the locking arm moves to a second position, so that during the pivoting process of the operating lever, the notch of the elastic arm always accommodates the arc guide rail.

[0022] In the scheme of the lever-type electrical connector according to the present application, as an optional implementation method, in the pre-locking state of the lever-type electrical connector, the end of the locking arm is in the first position, and the front end of the locking block abuts against the end of the arc guide rail, thereby preventing the operating lever from pivoting to the final locking state.

[0023] In the scheme of the lever-type electrical connector according to the present application, as an optional implementation method, in the final locking state of the lever-type electrical connector, the end of the locking arm is in the first position, and the rear end of the locking block abuts against the end of the arc guide rail, thereby preventing the operating lever from pivoting to the initial locking state.

[0024] In the solution of the lever-type electrical connector according to the present application, as an optional implementation, the arc-shaped guide rail is provided on one side or both sides of the connector cover.

[0025] In the solution of the lever-type electrical connector according to the present application, as an optional implementation, a receiving cavity for receiving the elastic structure of the CPA device is provided in the transverse connecting portion of the joystick.

[0026] According to one aspect of the present application, a CPA device for a lever-type electrical connector is proposed, comprising: a body; an elastic ring structure formed at the front end of the body; and locking arms extending from both side surfaces of the body, wherein the extension direction of the locking arm is not coplanar with the body but is angled, the horizontal component of the angle corresponds to the front end of the body, and the vertical component of the angle corresponds to the lower side of the body, wherein a locking block is formed at the end of the locking arm, and a notch opening inward is provided at the distal end of the locking arm of the CPA device at the connection with the locking block.

However, those skilled in the art will recognize that various embodiments can be implemented without one or more specific details or with other replacement and / or additional methods, materials or components.

However, this patent application can be implemented without specific details. In addition, it should be understood that the various embodiments shown in the drawings are illustrative representations and are not necessarily drawn to scale.

[0049] The various embodiments and variations of the present patent application are further described below in conjunction with the accompanying drawings.

[0050] Figure 2 A schematic diagram showing a lever-type electrical connector 200 with a resilient CPA device 260 according to an embodiment of the present application is shown. Figure 3 show Figure 2 Schematic diagram of the lever-type electrical connector 200 and the resilient CPA device 260 in a separated state. Figure 2 and Figure 3 As shown, according to one implementation of the present application, a lever-type electrical connector 200 includes a terminal housing 220 for accommodating terminals, a cover 210 for mounting on the incoming line end of the terminal housing 220, and an operating lever 230 for pivotally mounting on the terminal housing 210. The operating lever 230 of the lever-type electrical connector 200 can use a connection position retaining device (CPA) to achieve position locking in an initial locking state and a final locking state. This CPA device is referred to as a resilient CPA device 260, or simply a CPA device 260, in the present application. Further, as Figure 2 As shown, the lever 230 is configured to be pivotally mounted on the terminal housing 220, and as a whole comprises a pair of left and right arms, and a transverse connecting portion 235 (which may also be called a transverse handle, a crossbar, or an operating portion, etc., as customary) connecting the ends of the left and right arms. The lever 230 may thus have a substantially U-shaped structure, but the present application is not limited thereto.

[0051] The transverse connection portion 235 of the operating rod 230 is configured to receive the resilient CPA device 260 and enable the CPA device 260 to move forward and backward within a certain range of travel after being mounted on the operating rod 230 .

[0052] Figure 4A yes Figure 3 A first perspective view of the resilient CPA device 260 is shown, Figure 4B yes Figure 3FIG. 5 is a schematic diagram showing the positional movement of the resilient CPA device 260 relative to the joystick 230 after the resilient CPA device 260 is pressed. Figure 4A and Figure 4B As can be seen, the CPA device 260 includes a flat and roughly rectangular body 261, and an elastic ring 262 structure is provided at the front of the body 261 (the front of the body corresponds to the direction in which it is installed in the joystick 230). At the rear of the body 261, a raised pressing portion 266 may be provided for easy operation. On the left and right sides of the body 261, raised sliders 265 may be provided.

[0053] Figure 5A and Figure 5B 2 is a schematic diagram showing the positional movement of the resilient CPA device relative to the joystick 230 after being pressed. Fig. 6A A diagram showing the front end of the operating lever 230 according to an embodiment of the present application (the front end of the operating lever corresponds to the direction in which the operating lever is facing when it rotates from the pre-locking to the final locking). Figure 6B A diagram showing the rear end of the operating lever 230 according to an embodiment of the present application (the rear end of the operating lever corresponds to the direction in which it is facing when it rotates from the final lock to the pre-lock). Figure 6C A bottom side view of a joystick 230 is shown according to an embodiment of the present application. Fig.6D A vertical cross-sectional view of a joystick 230 according to an embodiment of the present application is shown. Fig. 6E A side view of a joystick 230 according to an embodiment of the present application is shown.

[0054] Combination Figure 5A-5B 6A-6E show that, with the aid of the sliders 265 on the left and right sides of the main body 261, the CPA device 260 can be installed into a pair of mounting grooves 2302 on the inner sides of the upper ends of the left arm 239L and the right arm 239R of the joystick 230, and the elastic ring 262 can be installed into a accommodating cavity structure 2303 of the transverse connecting portion 235 of the joystick 230.

[0055] Reference again Figure 4A and Figure 4B, a locking arm 263 is extended from each slider 265 on both sides of the body 261. A locking block 264 is provided at the end of each locking arm 263. The extension direction of the locking arm 263 is not coplanar with the body 261, but forms an angle with the body 261. The horizontal component of the angle corresponds to the front end of the body, and the vertical component of the angle corresponds to the lower side of the body. Further, the angle formed by the locking arm 263 and the body 261 is constructed so that when the CPA device 260 is installed on the joystick 230, the extension direction of the rear half of the locking arm 263 is substantially consistent with the extension direction of the left arm and the right arm of the joystick 230. As further shown in FIG. 5 , the mounting slot 2302 is arc-shaped, so that the forward and backward movement of the body 261 of the CPA device 260 is converted into the up and down movement of the end of the locking arm 263.

[0056] The elastic ring 262 is configured to be deformable under a certain force. For example, the elastic ring 262 may be initially circular, and when its two sides are squeezed, it becomes an ellipse. Figure 5A When the CPA device 260 is installed in the operating rod 230, the elastic ring 262 is deformed by applying force to the pressing portion 266, so that the body 261 of the CPA device 260 can be further pushed along the installation slide groove 2302, and the positions of the locking blocks 264 at the ends of the locking arms 263 on both sides of the body 261 are lowered (such as Figure 5A After the CPA device 260 is pressed into place, the position of the locking block 264 at the end of the locking arm 263 finally drops to Figure 5B It can be understood that when the force applied to the pressing portion 266 is released, the elastic ring 262 rebounds, and its rebound force causes the body 261 of the CPA device 260 to retreat along the installation slot 2302, and causes the positions of the locking blocks 264 at the ends of the locking arms 263 on both sides of the body 261 to rise again and return to the position shown. Figure 5A Position shown.

[0057] Further Figure 4A and 4B As shown, a notch 2635 opening inward is provided at the distal end of the locking arm 263 of the CPA device 260 and at the connection with the locking block 264. The size of the notch 2635 is configured to receive the arc-shaped guide rail 225 on the terminal housing 220.

[0058] Fig. 7A 2 is a cross-sectional view showing the positional relationship between the resilient CPA device 260 and the connector housing 210 when the lever 230 is in the pre-lock position. Figure 7B show Fig. 7A In the state shown, there is a physical interference relationship between the resilient CPA device 260 and the arc-shaped guide rail 225 on the surface of the cover 210 for achieving pre-locking. Figure 8 2 is a cross-sectional view showing the positional relationship between the resilient CPA device 260 and the connector housing 210 during the process of the operating lever 230 rotating from the pre-locking position to the final locking position. Fig. 9A It is a cross-sectional view showing the positional relationship between the resilient CPA device 260 and the connector housing 210 when the operating lever 230 is in the final locking position. Fig. 9B show Fig. 9A In the state shown, there is a physical interference relationship between the resilient CPA device 260 and the arc-shaped guide rail 225 on the surface of the cover 210 for achieving final locking.

[0059] Fig. 7A This corresponds to the state of the connector when it is initially shipped. At this time, the CPA device 260 is pre-installed on the operating lever 230, and the pressing portion 266 of the CPA device 260 is not subjected to force. In this state, the front end surface of the locking block 264 at the end of the locking arm 263 of the CPA device 260 abuts against the first end surface (i.e., the left end surface in the figure) of the arc-shaped guide rail 225 on the surface of the housing 210, thereby forming a hard interference. Figure 7B As shown, a locking protrusion 2645 may be further provided in the middle of the front end surface of the locking block 264, so as to prevent the locking block 264 from being raised and increase the stability of the assembly.

[0060] Figure 8 The corresponding operation stage is that the connector lever 230 rotates from the pre-locking position to the final locking position. At this time, the interference between the locking block 264 and the arc-shaped guide rail 225 is released. This release is achieved by lowering the position of the locking block 264. More specifically, by applying an operating force to the pressing portion 266 of the CPA device 260, the elastic ring 262 of the CPA device 260 can be deformed, and the body 261 of the CPA device 260 is therefore further pushed into the lever 230, which in turn causes the locking arm 263 and the locking block 264 to descend. In the lowered position, the notch 2635 on the locking arm 263 can just accommodate the arc-shaped guide rail 225, so that the connector lever 230 can be as shown. Figure 8 At the same time, because of the matching relationship between the notch 2635 on the locking arm 263 and the arc-shaped guide rail 225, even if the pressing portion 266 is not continuously subjected to operating force, the position of the locking block 264 will not be lifted.

[0061] Fig. 9A This corresponds to the final locking state of the connector. At this time, the locking block 264 has rotated beyond the second end face of the arc-shaped guide rail 225 (i.e., the right end face in the figure), and the notch 2635 on the locking arm 263 and the arc-shaped guide rail 225 have been disengaged. Therefore, under the rebound force of the elastic ring 262, the position of the locking arm 263 and the locking block 264 is automatically raised. At this time, Fig. 9BAs shown, the rear end of the locking block 264 abuts against the second end surface of the arc-shaped guide rail 225. This hard interference ensures that the operating rod 230 will not release the final lock due to accidental counterclockwise rotation.

[0062] It is worth pointing out that, since it is not necessary to keep pressing the pressing portion 266 of the CPA device during the process of rotating the joystick, the position lifting of the locking arm 263 and the locking block 264 will automatically occur after entering the final locking position.

[0063] Similarly, during the reverse rotation from the final locking position to the initial locking position, it is not necessary to keep pressing the pressing portion 266 of the CPA device, so the position lifting of the locking arm 263 and the locking block 264 will automatically occur after entering the pre-locking position.

[0064] Optionally, a snap-fit ​​structure may be provided at the lower front end of the CPA device 260 , so that when the lever is rotated to the final locking position, the CPA device 260 is snap-fitted with the matching structure on the cover 210 by means of the snap-fit ​​structure.

[0065] As a variation, the arc-shaped guide rail 225 may be provided on only one side of the connector housing 210 .

[0066] As a variation, the elastic ring 262 can be replaced by other structures with elastic resilience, such as a spring. In fact, any elastic structure in a broad sense can be arranged on one side of the body of the CPA device to apply a resilience to the CPA device.

[0067] Compared with the technology described in the background technology section, the above-mentioned embodiments of the present application have one or more of the following technical benefits: 1) The embodiments of the present application integrate a joystick locking structure on the CPA device to ensure the high stability and large holding force of the joystick in the initial position and the final locking position; 2) The CPA device designed in the present application does not include a traditional lever arm structure, avoiding the problem of easy deformation and breakage of the elastic lever arm of the CPA device; 3) The design of the embodiments of the present application is more ergonomic and has good operability. After the unlocking operation is released, the CPA device can automatically return to the locked position, and the main body surface of the CPA device provides a larger operating area, which is conducive to the operation of miniaturized equipment.
