[0002] An electrical connector is an electronic engineering device used to achieve electrical connections between devices, between apparatuses, and between electrical components. Currently, electrical connectors generally include a plug and a socket that are inserted into each other. The plug usually has pin terminals, and the socket has jack terminals, and electrical connection is achieved through the insertion of the two terminals into each other.

[0003] However, due to factors such as assembly errors, it may be impossible for the two terminals to be inserted accurately in alignment, which needs to be solved urgently. Summary of the Utility Model

[0004] Based on this, in view of the problem that it is difficult for the two inserted terminals in an electrical connector to be inserted accurately in alignment, it is necessary to provide a jack-type terminal structure and a terminal strip.

[0005] On the one hand, the present application provides a jack-type terminal structure. The jack-type terminal structure includes a first section and a second section. The first section is used for limited cooperation with an insulator; the second section is connected end to end with the first section. The second section is provided with an insertion cavity. One end of the second section away from the first section protrudes radially outward to form a guiding disc. The guiding disc includes a guiding surface on a side facing away from the first section. The central region of the guiding surface is concave inward along the axis relative to the edge region. The insertion cavity forms an opening in the central region of the guiding surface for a pin to be inserted into.

[0006] In one embodiment, the second section includes at least two claws. At least two claws are arranged along the circumferential direction of the second section to enclose the insertion cavity. One end of at least part of the claws away from the first section is folded radially inward, so that in the direction away from the first section along the axis of the jack-type terminal structure, the size of at least part of the region of the insertion cavity gradually decreases; the guiding disc includes a plurality of disc parts, and the plurality of disc parts are respectively arranged at one end of the claws away from the first section, and the disc parts protrude radially outward relative to the claws.

[0007] In one embodiment, in the circumferential direction of the second section, adjacent claws are arranged at intervals.

[0008] In one embodiment, a limiting part is protrudingly arranged on the outer periphery of the first section, and the limiting part is used for interference press-fitting with the insulator.

[0009] In one embodiment, the limiting portion includes a first limiting portion, and in the direction gradually approaching the second section along the axis of the socket-type terminal structure, the size of at least a part of the structure of the first limiting portion gradually decreases.

[0010] In one embodiment, the limiting portion further includes a second limiting portion, and the second limiting portion extends along the axis of the socket-type terminal structure and is strip-shaped.

[0011] In one embodiment, the number of the first limiting portions is multiple, and the number of the second limiting portions is also multiple; along the circumferential direction of the first section, the multiple first limiting portions are arranged at equal intervals, and the multiple second limiting portions are arranged at equal intervals; along the axis of the first section, at least one of the first limiting portions is arranged in a staggered manner with one of the second limiting portions.

[0012] In one embodiment, the first section is hollow to form a through hole, the first section includes a cup mouth at one end far from the second section, the cup mouth is communicated with the through hole, the second section is provided with a blocking portion, and the blocking portion is formed by inward concavity of an area on the outer periphery of the first section, so that the cross-sectional dimension of the through hole at the blocking portion is smaller than other areas of the through hole.

[0013] In one embodiment, the socket-type terminal structure is provided with a docking seam extending along the axis, the docking seam includes an opposite first surface and a second surface, and the socket-type terminal structure can be wound from a processing state to a forming state by stamping;

[0014] When the socket-type terminal structure is in the processing state, the socket-type terminal structure is in a flat plate shape, and the first surface and the second surface are arranged back to back;

[0015] When the socket-type terminal structure is in the processing state, the socket-type terminal structure is in a hollow tubular shape, and the first surface and the second surface are arranged at intervals facing each other or in contact with each other to form the docking seam.

[0016] The present invention itself also provides a terminal strip, which includes a connecting strip and a plurality of the socket-type terminal structures as described above, and the plurality of socket-type terminal structures are connected to the connecting strip at intervals.

[0017] In the above-mentioned socket-type terminal structure, the second section is provided with a guiding disc, the central area of the guiding disc is provided with an opening for the insertion pin to insert, and the central area of the guiding surface of the guiding disc is concave. Therefore, when there is a certain alignment deviation between the insertion pin and the socket-type terminal structure, the guiding surface can guide the insertion pin to gradually insert into the opening to achieve accurate insertion. Further, since the guiding disc is formed by the end of the second section protruding radially outward, the guiding disc can also reduce the probability of the insertion pin inserting into the gap between the insulator and the socket-type terminal structure, and improve the smoothness of the insertion.

Detailed Description of the Embodiments

[0026] In order to make the above objects, features and advantages of the present application more obvious and understandable, the following detailed description of the specific embodiments of the present application will be given in conjunction with the accompanying drawings. Many specific details are set forth in the following description in order to fully understand 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.

[0027] In the description of the present application, it should be understood that if there are 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., the orientation or positional relationship indicated by these terms is based on the orientation or positional relationship shown in the 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 thus should not be construed as a limitation on the present application.

[0028] In addition, if there are terms such as "first" and "second", these terms are only used 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 there is a term "plurality", the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0029] In the present application, unless otherwise clearly specified and limited, if there are terms such as "mounted", "connected", "coupled", "fixed", etc., these terms should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may 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.

[0030] In the present application, unless otherwise clearly specified and limited, if there is a description such as a first feature being "on" or "under" a second feature, the meaning may 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 may mean that the first feature is directly above or obliquely above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. The first feature being "under", "beneath" and "underneath" the second feature may be that the first feature is directly below or obliquely below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] It should be noted that if an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there may 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 present, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are only for illustrative purposes and do not represent the only implementation.

[0032] The current terminal structure is generally in the shape of a slender rod or column. Therefore, in order to clearly illustrate the jack-type terminal structure 100 in the embodiments of the present application, with reference to the axis O of the slender rod or column structure, the circumferential direction S described in the following embodiments is the direction around the axis O.

[0033] Refer to Figures 1 to 4 , a jack-type terminal structure 100 provided in an embodiment of the present application includes a first section 200 and a second section 300 connected end to end. The first section 200 is used for limiting and cooperating with an insulator (not shown in the figure, the same below). The second section 300 is provided with an insertion cavity 310 for inserting and cooperating with a pin (not shown in the figure, the same below). One end of the second section 300 away from the first section 200 protrudes radially outward to form a guiding disk 320. The guiding disk 320 includes a guiding surface 320a on the side facing away from the first section 200. The central region 321 of the guiding surface 320a is concave inward along the axis O relative to the edge region 322. The insertion cavity 310 forms an opening 311 in the central region 321 of the guiding surface 320a for the pin to insert.

[0034] In the above jack-type terminal structure 100, the second section 300 is provided with a guiding disk 320. The central region 321 of the guiding disk 320 is provided with an opening 311 for the pin to insert, and the central region 321 of the guiding surface 320a of the guiding disk 320 is concave. Therefore, when there is a certain alignment deviation between the pin and the jack-type terminal structure 100, the guiding surface 320a can guide the pin to gradually insert into the opening 311 to achieve accurate insertion. Further, since the guiding disk 320 is formed by the end of the second section 300 protruding radially outward, the guiding disk 320 can also reduce the probability of the pin inserting into the gap between the insulator and the jack-type terminal structure 100 and improve the smoothness of insertion.

[0035] It should be understood that the central region 321 of the guiding surface 320a is relative to the edge region 322 (as Figure 2 shown), and the size of the concave region 323 on the guiding disk 320 can be adjusted according to requirements without being limited by the size of the central region 321, and no specific limitation is made here.

[0036] Further, the embodiments of the present application do not limit the concave form of the guiding surface 320a. For example, the guiding surface 320a can be concave in the form of an inclined surface, a curved surface, etc.

[0037] Please continue to refer to Figure 4 , in one embodiment, the second section 300 includes at least two clamping claws 330. The at least two clamping claws 330 are arranged along the circumferential direction S of the second section 300 to enclose the above-mentioned insertion cavity 310. One end of at least a part of the clamping claws 330 away from the first section 200 is turned over radially inward, so that in the direction away from the first section 200 along the axis O of the jack-type terminal structure 100, the size of at least a part of the area of the insertion cavity 310 gradually decreases. Therefore, when the insertion cavity 310 is used for inserting a pin, the clamping claws 330 can more firmly clamp the pin to achieve stable insertion.

[0038] Such as Figure 4 , the guiding disk 320 includes a plurality of disk parts 324. The plurality of disk parts 324 are respectively arranged at one end of the clamping claws 330 away from the first section 200, and the disk parts 324 protrude radially outward relative to the clamping claws 330. Arranging the disk parts 324 at one end of the clamping claws 330 away from the first section 200 can reduce the probability of the problem that the inward turning of the clamping claws 330 results in a small end size and inconvenience in aligning the pin with the opening 311.

[0039] It should be noted that since the installation hole (not shown in the figure, the same below) for the jack-type terminal structure 100 to penetrate and be installed in the insulator is generally a cylindrical hole, the inward turning of the clamping claws 330 easily causes a certain gap between the outer periphery of the second section 300 and the inner wall of the installation hole. Therefore, arranging the guiding disk 320 as described above in combination with the inward-turned clamping claws 330 can block and guide the pin to be inserted into the opening 311, so as to reduce the probability that the pin is misinserted into the gap when the pin is inserted into the jack-type terminal structure 100.

[0040] Please refer to Figure 1 and Figure 4 , in one embodiment, in the circumferential direction S of the second section 300, the adjacent clamping claws 330 are arranged at intervals to reduce the probability of mutual interference and jamming between the adjacent clamping claws 330. Figure 4 The number of the shown clamping claws 330 is two, and the number of the clamping claws 330 can also be set to 3, 4, 5, 6, etc. according to requirements, and no limitation is made here. The clamping claws 330 have elastic properties.

[0041] Please refer to Figure 1 and Figure 5 , in one embodiment, a limiting portion 210 is convexly provided on the outer periphery of the first section 200. The limiting portion 210 is used for interference press-fitting with the insulator. Through the interference fit of the limiting portion 210 and the insulator, the stability of the jack-type terminal structure 100 installed in the insulator can be improved.

[0042] Please refer to Figure 5 , in one embodiment, the limiting portion 210 includes a first limiting portion 211. In the direction of gradually approaching the second section 300 along the axis O of the socket-type terminal structure 100 ( Figure 5 the O1 direction shown), the size of at least part of the structure of the first limiting portion 211 gradually decreases. It can be understood that the second section 300 is the end of the socket-type terminal structure 100 for plugging with the pin, so the second section 300 is usually also the part that first penetrates into the insulator. Therefore, for the structures of each region on the first limiting portion 211, the closer to the second section 300, the earlier it contacts the insulator. For the structures of each region on the first limiting portion 211, the larger the size, the greater the resistance during interference fit and the better the stability. Thus, by setting the size of at least part of the structure of the first limiting portion 211 to gradually decrease in the direction of gradually approaching the second section 300 along the axis O of the socket-type terminal structure 100, the region with a smaller size can gradually guide the region with a larger size to have an interference fit with the insulator, facilitating installation.

[0043] Please refer to Figure 1 , in one embodiment, the thickness dimensions of each region of the first limiting portion 211 in the radial direction can be equal, and the shape of the first limiting portion 211 in the arc-shaped cross-section perpendicular to the radial direction can be a triangle, a trapezoid, etc.

[0044] Furthermore, the number of the first limiting portions 211 can be multiple. Along the circumferential direction S of the first section 200, the multiple first limiting portions 211 are arranged at equal intervals to improve the limiting effect.

[0045] Please refer to again Figure 1 and Figure 5 , in one embodiment, the limiting portion 210 further includes a second limiting portion 212. The second limiting portion 212 extends along the axis O of the socket-type terminal structure 100 and is strip-shaped. Therefore, the second limiting portion 212 has a large contact area with the insulator on the axis O, which can reduce the probability of the socket-type terminal structure 100 moving axially relative to the insulator and improve the stability of the plugging of the socket-type terminal structure 100.

[0046] Furthermore, the number of the second limiting portions 212 can also be multiple. Along the circumferential direction S of the first section 200, the multiple second limiting portions 212 are arranged at equal intervals to improve the limiting effect.

[0047] Please refer to Figure 2 , in one embodiment, along the axis O of the first section 200, at least one first limiting portion 211 and one second limiting portion 212 are arranged in a staggered manner, which is convenient for giving full play to the limiting effects of the first limiting portion 211 and the second limiting portion 212.

[0048] Please refer toFigure 6 , in one embodiment, a through hole 220 is formed in the first section 200 in a hollow manner. The first section 200 includes a cup mouth 230 at one end away from the second section 300. The cup mouth 230 is used for welding with a cable, and the cup mouth 230 communicates with the through hole 220. The second section 300 is provided with a blocking portion 240, which is formed by concaving a region on the outer periphery of the first section 200, so that the cross-sectional dimension of the through hole 220 at the blocking portion 240 is smaller than that of other regions of the through hole 220. Since the cup mouth 230 is connected to the cable by welding, there will be flowing solder (in a molten state) at the cup mouth 230 during welding. Therefore, the blocking portion 240 is provided to block the solder at the cup mouth 230 to reduce the probability of its flowing in the through hole 220. The dimension of the blocking portion 240 concaved into the through hole 220 can be set according to actual requirements.

[0049] Furthermore, the blocking portion 240 can be arranged at a position on the axis O of the second section 300 close to the cup mouth 230 to effectively block the solder.

[0050] Please refer to Figure 5 , in one embodiment, the jack-type terminal structure 100 is provided with a butting seam 250. The butting seam 250 extends along the axis O, and the butting seam 250 includes opposite first surface 251 and second surface 252. The jack-type terminal structure 100 can be wound from a processing state to a forming state by stamping. When the jack-type terminal structure 100 is in the processing state, the jack-type terminal structure 100 is in a flat plate shape, and the first surface 251 and the second surface 252 are arranged back to back. When the jack-type terminal structure 100 is in the forming state, the jack-type terminal structure 100 is in a hollow tubular shape, and the first surface 251 and the second surface 252 are spaced opposite or in contact with each other to form the butting seam 250.

[0051] In other words, the jack-type terminal structure 100 provided in the present application can be formed by stamping a plate-shaped part to be processed, and the processing method is simple. Moreover, compared with the traditional turning-processed terminal structure, such an arrangement saves more materials. Further, the jack-type terminal structure 100 is formed by stamping, and the sizes of the openings, the size of the insertion cavity 310, and the consistency of the insertion and extraction forces are good, so that the reliability is high and the insertion and extraction are smooth when the jack-type terminal structure 100 is inserted and mated with the pin.

[0052] It should be noted that the jack-type terminal structure 100 provided in each embodiment of the present application can be easily formed by stamping. For example, during the stamping process, the guiding plate 320 and the plate portion 324 it includes can be extruded to form a convex structure. The inward turning of the claw 330 can be synchronously pressed radially inward during the winding process of the jack-type terminal structure 100 to form an inward-turned state. Similarly, the insertion cavity 310 in the first section 200 and the through hole 220 in the second section 300 can be formed as hollow cavities during the winding process. The first limiting portion 211, the second limiting portion 212, and the blocking portion 240 can also be directly formed into a convex or concave state by stamping.

[0053] Please refer to Figure 7 , an embodiment of the present application further provides a terminal strip 10. The terminal strip 10 includes a connecting strip 400 and a plurality of jack-type terminal structures 100, and the plurality of jack-type terminal structures 100 are connected to the connecting strip 400 at intervals. During stamping processing, the plate-shaped workpiece to be processed can be directly stamped to obtain the terminal strip 10. Since the jack-type terminal structures 100 are connected by the connecting strip 400, continuous local electroplating can be used during surface treatment to reduce the electroplating cost.

[0054] In one embodiment, positioning holes 410 are provided on the connecting strip 400 for positioning during stamping. To facilitate understanding of the stamping process of the jack-type terminal structure, a simple description is given below:

[0055] S1, Provide a sheet. The shape and specific dimensions of the sheet can be adaptively selected according to the required jack-type terminal structure 100.

[0056] S2, Punch positioning holes 410 in the sheet to facilitate positioning in subsequent processes.

[0057] S3, Punch the shape of one end of the jack-type terminal structure 100 when it is unfolded on the sheet. For example, at this time, the shapes of the claw 330, the plate portion 324, and the guiding surface 320a can be punched out.

[0058] S4, Punch the shape of the other end of the jack-type terminal structure 100 when it is unfolded on the sheet. For example, at this time, the shape of the cup mouth 230 when it is unfolded can be punched out.

[0059] S5, Stamp and remove the connecting material between adjacent jack-type terminal structures 100 on the sheet.

[0060] S6, Stamp the limiting portion 210 and the blocking portion 240 on the sheet.

[0061] S7, Round the sheet to form the jack-type terminal structure 100.

[0062] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0063] The above-described embodiments only express several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
