Abstract
Description
Technical Field
[0001] The present application relates to the technical field of electrical connectors, and particularly to a snap-type terminal and an electrical connector. Background Art
[0002] As a key component for realizing circuit connection, the core structure of an electrical connector generally includes an insulator and conductive terminals inserted into its inner hole. In traditional technical solutions, the terminals mainly rely on the outward-turning tongue structure to abut against the stepped limiting part in the inner cavity of the insulator to achieve the anti-retreat function after insertion. However, due to the precision requirements for the fitting clearance between the terminals and the insulator, the outward-turning angle and deformation amount of the tongue need to be strictly controlled, resulting in that the tongue structure is not easily elastically deformed during the insertion process, thus increasing the process difficulty of terminal assembly. Summary of the Invention
[0003] Based on this, it is necessary to provide a snap-type terminal and an electrical connector for the above problems.
[0004] On the one hand, the present application provides a snap-type terminal, which includes a body and a tongue. The body is hollow, and an exposed window is provided on one side of the body. The tongue is an elastic member, which includes a connecting end and a snap end. The connecting end and the snap end are oppositely arranged. The connecting end is connected to the side of the body opposite to the exposed window. The tongue turns towards the inside of the body, and the snap end is exposed outside the body through the exposed window. The snap end is used for snap connection with an insulator.
[0005] In one embodiment, the tongue includes a first section, one end of the first section is the connecting end, the first section is curved and protrudes towards the side where the connecting end is located, and in the direction along the axis of the body, the region of the first section that is farther away from the connecting end is closer to the exposed window in the direction perpendicular to the axis.
[0006] In one embodiment, the tongue includes a second section. One end of the second section is connected to the first section, and the other end is the snap end. The second section is curved and protrudes towards the side away from the side where the connecting end is located, and in the direction along the axis of the body, the region of the second section that is farther away from the connecting end is also farther away from the connecting end in the direction perpendicular to the axis.
[0007] In one embodiment, the ratio of the length to the thickness of the tongue is between 10:1 and 25:1.
[0008] In one embodiment, the tongue can be elastically turned. During the turning process of the tongue, the snap end can respectively move to the positions abutting against the two opposite side walls of the exposed window.
[0009] In one embodiment, the body includes a shell tube and a convex ring. The convex ring protrudes from the shell tube. The convex ring is spaced from the clamping end, and the convex ring is located on a side of the clamping end away from the connection end. The convex ring is used to abut against the insulator.
[0010] In one embodiment, the body includes a plug shaft section and a shell tube. The plug shaft section includes at least two clamping arms. At least two of the clamping arms are connected to the shell tube, and at least two of the clamping arms are arranged at intervals in the circumferential direction around the shell tube. The clamping arms are elastic bodies, and at least two of the clamping arms can elastically open and close in directions approaching and separating from each other. Wherein, each clamping arm includes an arm body and a contact part. The contact part is arranged on the arm body, and the contact part protrudes radially inward in an arc shape. The contact part is used to contact the pin terminal.
[0011] In one embodiment, a forming window is formed on a side of the body opposite to the exposed window. The clamping type terminal includes a forming body. The forming body is used to form a latching tongue. One end of the forming body is connected to the body. The forming body is used to be processed and converted from an initial state to a formed state. The forming body in the initial state is located in the forming window, and the forming body in the formed state is the latching tongue.
[0012] In one embodiment, the clamping type terminal is provided with a docking seam extending along the axis. The docking seam includes an opposite first surface and a second surface. The clamping type terminal can be formed by stamping from an initial state into a formed state. When the clamping type terminal is in the initial state, the clamping type terminal is in a flat plate shape, and the first surface and the second surface are opposite to each other. When the clamping type terminal is in the formed state, the clamping type terminal is in a hollow tubular shape, and the first surface and the second surface are spaced opposite to each other or in contact with each other to form the docking seam.
[0013] On the other hand, the present application also provides an electrical connector, and the electrical connector includes the clamping type terminal as described above.
[0014] In the above snap-in type terminal, the connecting end of the tongue is connected to the side of the body opposite to the exposed window, and the snap-in end of the tongue is exposed outside the body through the exposed window. Compared with directly turning outwards the tongue, in the present application, the tongue turns outwards to the other side through the inside of the body. When the tongue is turned and deformed, it has a larger rotation radius, so it is more convenient to be deformed during the insertion process of the snap-in type terminal, reducing the insertion difficulty. Further, the tongue of the snap-in type terminal provided in the present application has a relatively larger rotation radius. Therefore, when the free end (i.e., the snap-in end) of the tongue moves the same displacement, the turning angle of the tongue is smaller, and the stress at the root of the tongue (i.e., at the connecting end) is lower, and it is less likely to exceed the elastic deformation limit of the tongue. With such a setting, the tongue is not likely to break and has a higher service life. Moreover, as the part of the snap-in type terminal for connecting with the insulator, the tongue is easy to deform, so to a certain extent, it can absorb the vibration transmitted from the outside to the body through the insulator, improving the stability of the electrical connection.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] To make the above objects, features, and advantages of the present application more apparent and understandable, the following provides a detailed description of the specific embodiments of the present application in conjunction with the accompanying drawings. A lot of specific details are set forth in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.
[0022] In the description of the present application, it should be understood that if terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or positional relationship indicated by these terms is based on the orientation or positional relationship shown in the accompanying drawings. These are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present application.
[0023] In addition, if terms such as "first" and "second" appear, these terms are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.
[0024] In the present application, unless otherwise clearly specified and limited, if terms such as "install", "connect", "couple", "fix", etc. appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.
[0025] In this application, unless otherwise clearly specified and defined, if there is a description such as a first feature being "on" or "under" a second feature, the meaning can be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature can mean that the first feature is directly above or obliquely above the second feature, or simply indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature can be that the first feature is directly below or obliquely below the second feature, or simply indicates that the first feature has a lower horizontal height than the second feature.
[0026] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or there can also be an intermediate element. If an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If so, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation.
[0027] Connectors in the traditional technology usually include an insulator and terminals. The insulator is provided with mounting holes, and the terminals are inserted into the mounting holes. At the same time, to improve the axial position stability of the terminals, the terminals are usually also provided with lugs. A positioning platform protrudes in the mounting hole, and the axial position stability of the terminals is improved by the lugs abutting against the positioning platform, facilitating mating. The lugs in the traditional technology usually directly turn outwards relative to the terminal body. However, the terminal body and the mounting hole usually have almost the same radial dimension, and the radial gap between the two is small. Therefore, based on the small gap between the terminal body and the mounting hole, the size of the outward turning of the lugs is also limited, resulting in a small turning radius of the lugs, being not easily deformed, and prone to the problem of stress concentration at the root.
[0028] To solve the above problems, this application provides a snap-in type terminal. The snap-in type terminal includes a body and a lug. The lug turns into the body and extends out of the body from the other side. The part of the lug extending out of the body is used for snap-connecting with the insulator. With such a setting, in the case where the body and the inner hole of the insulator have the same gap size, the lug can have a larger turning radius, so it is more easily deformed, and the smoothness of the insertion of the snap-in type terminal can be improved. The snap-in type terminal and an electrical connector including the snap-in type terminal will be described in detail below in conjunction with specific embodiments and the accompanying drawings of the specification.
[0029] Refer to Figure 1 and Figure 2 , Figure 1 is a schematic cross-sectional view of an exemplary insulator provided by an embodiment of this application. Figure 2The axonometric schematic diagram of the snap-in type terminal provided by an embodiment of the present application is shown. An embodiment of the present application provides an electrical connector, and the electrical connector includes a snap-in type terminal 10. The electrical connector further includes an insulator 20, and the insulator 20 is provided with a mounting hole 21. The snap-in type terminal 10 is inserted through the mounting hole 21 and is in limiting cooperation with the hole wall of the mounting hole 21.
[0030] Referring to Figure 2 , an embodiment of the present application provides a snap-in type terminal 10. The snap-in type terminal 10 is used to be inserted into the insulator 20 and is in snap-fit connection with the insulator 20. The snap-in type terminal 10 includes a body 100 and a tongue 200. The tongue 200 is an elastic member, and the tongue 200 is arranged on the body 100. The tongue 200 is used to be in snap-fit connection with the insulator 20. The body 100 is hollowly arranged, and an exposed window 101 is opened on one side of the body 100. The tongue 200 includes a connecting end 201 and a snap-in end 202. The connecting end 201 and the snap-in end 202 are oppositely arranged. The snap-in end 202 is used to be in snap-fit connection with the insulator 20. The connecting end 201 is connected to the side of the body 100 opposite to the exposed window 101. The tongue 200 turns towards the inside of the body 100. The snap-in end 202 is exposed outside the body 100 through the exposed window 101.
[0031] In the above-mentioned snap-in type terminal 10, the connecting end 201 of the tongue 200 is connected to the side of the body 100 opposite to the exposed window 101, and the snap-in end 202 of the tongue 200 is exposed outside the body 100 through the exposed window 101. Compared with the configuration where the tongue 200 directly turns outwards, the tongue 200 provided by the present application turns outwards to the other side through the inside of the body 100. When the tongue 200 is deformed, it has a larger turning radius. Therefore, it is more convenient to deform during the insertion process of the snap-in type terminal 10, reducing the insertion difficulty. Further, the tongue 200 of the snap-in type terminal 10 provided by the present application has a relatively larger turning radius. Therefore, when the free end (i.e., the snap-in end 202) of the tongue 200 moves the same displacement, the turning angle of the tongue 200 is smaller, and the stress at the root of the tongue 200 (i.e., at the connecting end 201) is lower, and it is less likely to exceed the elastic deformation limit of the tongue 200. Therefore, it has a higher service life. Moreover, the tongue 200, as the part of the snap-in type terminal 10 used to connect with the insulator 20, is easy to deform. Therefore, to a certain extent, it can absorb the vibration transmitted from the outside to the body 100 through the insulator 20, improving the stability of the electrical connection.
[0032] In addition, when the tongue 200 still adopts the form of direct outward turning, on this basis, the length of the tongue 200 is extended and the included angle between the tongue 200 and the axis O of the body 100 is reduced, so that the tongue 200 is substantially in a posture that fits the outer periphery of the body 100. Although such a setting can also increase the flipping radius of the tongue 200, on the one hand, the included angle between the tongue 200 and the axis O of the body 100 is too small, which is inconvenient for processing and shaping; on the other hand, the axial dimension of the tongue 200 is relatively long, which will cause the axial dimension of the snap-in terminal 10 to have to be extended accordingly, which is not conducive to the miniaturization design of the electrical connector.
[0033] Please refer to Figure 2 and Figure 4 , in an embodiment, the snap-in terminal 10 has a first side 11 and a second side 12, and the first side 11 and the second side 12 are arranged back to back. The exposed windows 101 are distributed on the first side 11. The connecting end 201 of the tongue 200 is connected to the area of the body 100 located on the second side 12, and the tongue 200 turns inward into the body 100 to flip to the first side 11.
[0034] Please refer to Figure 5 , in combination with Figure 3 and Figure 4 , in an embodiment, the tongue 200 includes a first section 210 and a second section 220. One end of the first section 210 is the connecting end 201, one end of the second section 220 is connected to the first section 210, and the other end of the second section 220 is the snap-in end 202.
[0035] Further, the first section 210 is curved and convex toward the side where the connecting end 201 is located, and the area of the first section 210 that is farther away from the connecting end 201 in the direction along the axis O of the body 100 is closer to the exposed window 101 in the direction perpendicular to the axis O. In other words, taking the perspective shown in Figure 4 and Figure 5 as an example, if a rectangular coordinate system is established with the center of the arc of the first section 210 as the origin, the first section 210 is in the shape of an arc located in the third quadrant. With such a setting, the connecting end 201 can be smoothly connected to the body 100 to reduce the stress concentration at the connecting end 201 and improve the service life of the tongue 200.
[0036] Please refer to Figure 5 , in an embodiment, the first section 210 can be arranged to extend along the first distribution line S1. Figure 4 and Figure 5 In the perspective shown, in the direction along the axis O of the body 100 away from the connecting end 201, the slope of the first distribution line S1 gradually decreases. That is to say, the part of the first section 210 closer to the connecting end 201 has a larger slope, that is, the higher the coincidence degree with the axis O of the body 100, the easier it is to achieve a smooth transition connection.
[0037] Further, the second section 220 is curved and protrudes away from the side where the connection end 201 is located, and in the direction along the axis O of the main body 100, the region of the second section 220 that is farther from the connection end 201 is also farther from the connection end 201 in the direction perpendicular to the axis O. In other words, taking Figure 4 and Figure 5 the shown perspective as an example, if a rectangular coordinate system is established with the center of the arc of the second section 220 as the origin, the second section 220 is in the shape of an arc located in the first quadrant. With such a setting, the clamping end 202 and the region near it have an approximately the same extension direction as the outer periphery of the main body 100. Thus, when the clamping type terminal 10 is inserted into the insulator 20, the second section 220 can have a larger contact area with the inner wall of the insulator 20, facilitating the tongue 200 to be turned and deformed under the action of the insulator 20. In short, such a setting can improve the smoothness of inserting the clamping type terminal 10.
[0038] Please refer to Figure 5 , in one embodiment, the second section 220 can extend along the second distribution line S2. Figure 4 and Figure 5 In the shown perspective, in the direction along the axis O of the main body 100 away from the connection end 201, the slope of the second distribution line S2 gradually increases. That is to say, the closer the part of the second section 220 is to the clamping end 202, the greater the slope, which means the higher the coincidence degree with the axis O of the main body 100, and thus the easier it is to have a larger contact area with the insulator 20.
[0039] In one embodiment, the ratio of the length to the thickness of the tongue 200 is between 10:1 and 25:1. It can be understood that the larger the ratio of the length to the thickness of the tongue 200, the more convenient it is for the tongue 200 to deform. If the ratio of the length to the thickness of the tongue 200 is too large, it is not conducive to stably abutting against the insulator. Therefore, the ratio of the length to the thickness of the tongue 200 can be designed according to the actual situation. In this embodiment, the ratio of the length to the thickness of the tongue 200 can be adaptively designed according to factors such as the thickness, inner diameter of the clamping type terminal 10, and the size of the tongue 200 required to protrude out of the exposed window 101, which will not be elaborated here. As an example, the length of the tongue 200 can be the dimension of the tongue 200 along its distribution line (the first distribution line S1 or the second distribution line S2), and the thickness of the tongue 200 is the dimension of the tongue 200 in the direction perpendicular to the distribution line.
[0040] Please refer to Figure 4 and Figure 5, in one embodiment, the exposed window 101 has a certain axial span for the tongue 200 to flip and move. Further, the tongue 200 can flip elastically. During the flipping process of the tongue 200, the clamping end 202 can move to positions abutting against two opposite side walls of the exposed window 101 respectively. That is to say, under the abutting and limiting action of the exposed window 101, the tongue 200 cannot flip back into the body 100, so as to reduce the risk that the tongue 200 cannot rebound due to being limited by the body 100.
[0041] Please refer to Figure 3 , in combination with Figure 4 , in one embodiment, the body 100 includes a shell tube 110, a plug-in shaft section 120 and a convex ring 130. The convex ring 130 is arranged on the shell tube 110. The plug-in shaft section 120 is connected to one end of the shell tube 110 and is used for plugging and electrically connecting with the other terminal. It can be understood that on the axis O of the body 100, the clamping end 202 is farther away from the plug-in shaft section 120 in the direction of the axis O of the body 100.
[0042] Please refer to Figure 4 , in combination with Figure 1 , in one embodiment, the convex ring 130 protrudes from the shell tube 110 and is used for abutting against the insulator 20. The convex ring 130 and the clamping end 202 are arranged at intervals, and the convex ring 130 is located on the side of the clamping end 202 away from the connection end 201. The convex ring 130 and the clamping end 202 respectively abut against the insulator 20, and they cooperate with each other to completely position the clamping type terminal 10 relative to the insulator 20. Please refer to Figure 1 , when the clamping type terminal 10 is inserted into the mounting hole 21, the movement direction is denoted as the positive direction, and the direction opposite to the positive direction is the reverse direction. The insulator 20 includes a positioning table 22, and the positioning table 22 protrudes from the inner wall of the mounting hole 21. The clamping type terminal 10 can move along the positive direction to the position where the convex ring 130 abuts against the positioning table 22, and at this time, the clamping type terminal 10 is inserted in place. And at this time, the tongue 200 abuts against the other side of the positioning table 22 along the reverse direction to prevent the clamping type terminal 10 from retracting. The tongue 200 and the convex ring 130 cooperate with each other to enable the clamping type terminal 10 to be completely positioned axially.
[0043] Please refer to Figure 1, in one embodiment, the positioning table 22 has a third side 24 and a fourth side 25, and the third side 24 and the fourth side 25 are arranged axially away from each other. The third side 24 is used to abut against the convex ring 130, and the fourth side 25 is used to be clamped with the tongue 200. The positioning table 22 further has a chute 23, and the chute 23 penetrates from the third side 24 to the fourth side 25, and the chute 23 allows the tongue 200 to move from the third side 24 to the fourth side 25. Since the positioning table 22 is configured with the chute 23, the deformation amount of the tongue 200 during the sliding process from the third side 24 to the fourth side 25 is relatively reduced. At the same time, since the chute 23 is opened in a region on the circumference of the positioning table 22, the convex ring 130 can still be fully abutted and limited with the positioning table 22.
[0044] Please refer to Figure 2 and Figure 4 , in one embodiment, the plug shaft section 120 includes at least two clamping arms 121, and at least two clamping arms 121 are both connected to the shell tube 110, and at least two clamping arms 121 are arranged at intervals in the circumferential direction around the shell tube 110. The clamping arms 121 are elastic bodies, and at least two clamping arms 121 can elastically open and close in directions approaching and away from each other. Thus, the elastic opening and closing of the clamping arms 121 can clamp and fix the other terminal inserted with the snap-in type terminal 10. It can be understood that since at least two clamping arms 121 are arranged at intervals in the circumferential direction around the shell tube 110, at least two clamping arms 121 can enclose to form a jack 124 for the other terminal to be inserted. The elastic opening and closing of the clamping arms 121 can cause the jack 124 to elastically expand and retract accordingly.
[0045] Further, the clamping arm 121 includes an arm body 122 and a contact portion 123, and the contact portion 123 is arranged on the arm body 122. The contact portion 123 is convexly arranged in an arc shape toward the radial inner side, and the contact portion 123 is used to contact the pin terminal. Configuring the arc-shaped convex contact portion 123 can improve the stability of the clamping arm 121 when clamping the other terminal.
[0046] Please refer to Figure 4 and Figure 5 , in one embodiment, one side of the body 100 opposite to the exposed window 101 has a forming window 102. The snap-in type terminal 10 includes a forming body, and the forming body is used to form the tongue 200. One end of the forming body is connected to the body 100, and the other end is configured as a free end. The forming body is used to be processed and converted from an initial state to a formed state. The forming body in the initial state is located in the forming window 102, and the forming body in the formed state is the tongue 200. In other words, the solid area at the forming window 102 can be cut, turned inward into the body 100 and exposed through the exposed window 101 to form the tongue 200. In this embodiment, the tongue 200 is integrally provided with the body 100, so the processing and manufacturing are convenient. For example, the area where the forming window 102 is located can be stamped to obtain the forming body, and the forming body is turned inward into the body 100 and exposed through the exposed window 101 by relying on multiple stampings.
[0047] It should be emphasized that the present application does not limit that the formed body in the initial state completely fills the forming window 102. In other words, the present application does not limit that the shape of the formed body in the initial state is the same as that of the forming window 102, and the shape of the formed body and the shape of the forming window 102 can be configured according to actual needs.
[0048] In one embodiment, the snap-type terminal 10 as a whole can be formed by stamping a plate-shaped base material. For example, the snap-type terminal 10 is provided with a docking seam (not shown in the figure, the same below) extending along the axis O. The docking seam includes an opposite first surface (not shown in the figure, the same below) and a second surface (not shown in the figure, the same below). The snap-type terminal 10 can be wound from the initial state to the formed state by stamping. When the snap-type terminal 10 is in the initial state, the snap-type terminal 10 is in a flat plate shape, and the first surface and the second surface are arranged back to back. When the snap-type terminal 10 is in the formed state, the snap-type terminal 10 is in a hollow tubular shape, and the first surface and the second surface are spaced opposite or in contact with each other to form a docking seam. In this embodiment, the position of the docking seam can be specifically set according to actual processing requirements.
[0049] Furthermore, the interval between adjacent clamping arms 121 can be formed by stamping and removing part of the solid structure. Similarly, the forming window 102 and the exposed window 101 can also be formed by stamping and removing part of the solid structure. Shapes such as the bending or protruding of the contact portion 123, the locking tongue 200, and the convex ring 130 can also be formed by stamping.
[0050] Please refer to Figure 3 , in one embodiment, the main body 100 further includes a connecting shaft section 140. The connecting shaft section 140 is connected to one end of the shell tube 110 away from the plugging shaft section 120. The connecting shaft section 140 is used for connecting with a wire or for connecting with electronic components such as a circuit board. The connecting shaft section 140 can be connected to the wire or the circuit board by forms such as welding, riveting, and crimping.
