In addition, with the integration of domain control hosts, the shielding performance between connectors and wiring harnesses is required to be higher to resist mutual interference between signals; and the outer conductor of the vehicle-mounted connector that plays a shielding role is particularly critical in terms of its structural form. The outer conductor of the current vehicle-mounted connector is mainly made of the following two processes: 1. The stamping and rounding process is used. The stamping and rounding process is to stamp and roll the metal plate multiple times. There is a seam at the end of the top, and the seam cannot be completely fitted, resulting in electromagnetic signals still leaking through the seam; 2.

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1, reference Figures 1 to 7 , which is the first embodiment of the present invention, provides a high-shielding vehicle-mounted connector, which can achieve the purpose of shielding electromagnetic signals by manufacturing an integrally formed outer conductor of connectors of different sizes through a deep drawing process, and comprises an insulator 1, a center pin 2, an outer conductor 3 and a cable 4. An installation channel 101 is provided in the insulator 1, and the center pin 2 is fixedly installed inside the installation channel 101. The center pin 2 is inserted into the installation channel 101 from the end of the insulator 1 close to the cable 4 for installation. When the center pin 2 is not connected to the cable 4, the end of the center pin 2 close to the cable 4 is dovetailed. By bending and pressing the dovetail, the center pin 2 and the cable 4 are fixedly connected. The outer conductor 3 is a thin copper material. The shielding tube is integrally formed by a deep drawing process, and the outer conductor 3 is divided into a matching area 301, an assembly area 302 and a crimping area 303. The outer conductor 3 shielding tube integrally formed by the deep drawing process has no seams on the surface, better overall rigidity and better shielding performance. After the center pin 2 is installed inside the installation channel 101 of the insulator 1, the matching area 301 of the outer conductor 3 is sleeved and inserted from the end of the insulator 1 where the center pin 2 is installed, so that the matching area 301 and the assembly area 302 of the outer conductor 3 are sleeved on the outside of the insulator 1. At the same time, the cable 4 is peeled layer by layer, and then the cable 4 is inserted from the end of the outer conductor 3 away from the insulator 1, so that the core of the cable 4 is electrically connected to the center pin 2. The crimping area 303 of the outer conductor 3 is sleeved with a sleeve 5. The sleeve 5 is sleeved on the outside of the cable 4 before the cable 4 and the center pin 2 are fixedly connected, and then sleeved on the outside of the crimping area 303 of the outer conductor 3 after the cable 4 and the center pin 2 are connected, and the sleeve 5 is sleeved on the end away from the outer conductor 3 and the unstripped part of the cable 4, and the matching area 301 and the assembly area 302 on the outer conductor 3 that are sleeved on the outside of the insulator 1 correspond to the center pin 2 inside the insulator 1, so that when the connector is connected to the peripheral equipment through the center pin 2, the outer conductor 3 integrally formed by the deep drawing process shields the electromagnetic signal, so that there is no seam for the electromagnetic signal to leak.

[0030] A plurality of claw buckles 304 are arranged in an annular array on the mating area 301 on the outer conductor 3, and the gaps between the claw buckles 304 in the annular array form limiting grooves 305, and protrusions 306 are arranged on the claw buckles 304 in the annular array. A limiting strip 102 is arranged in an annular array on the circumferential side wall of the insulator 1, and the limiting strip 102 and the limiting groove 305 are correspondingly plugged, and an avoidance cavity 103 is opened between the limiting strips 102 in the annular array on the insulator 1, and the avoidance cavity 103 shrinks inwardly corresponding to the elastic deformation of the avoidance claw buckle 304, and a retaining ring 107 is arranged on the end of the insulator 1 away from the outer conductor 3, and the retaining ring 107 and the limiting strip 102 are fixedly connected.

[0031] When the outer conductor 3 is sleeved on the outside of the insulator 1, the limiting groove 305 at one end of the outer conductor 3 is correspondingly plugged into the limiting strip 102 on the insulator 1, thereby avoiding rotation between the outer conductor 3 and the insulator 1 after the sleeve connection. After the limiting strip 102 on the insulator 1 and the limiting groove 305 at one end of the outer conductor 3 are correspondingly plugged into, the limiting strip 102 and the claw 304 on the outer conductor 3 have the same outer diameter, and the protrusion 306 arranged on the claw 304 and the outer conductor 3 are integrally formed, which is also a feature formed by a deep drawing process. When the connector and the peripheral connector are matched and connected, the peripheral connector is sleeved on one end of the connector of the present invention. During the sleeve connection process, the protrusion 306 will be squeezed, causing the claw 304 to shrink inwardly toward the avoidance cavity 103. Therefore, after the peripheral connector is sleeved in place, when the protrusion 306 and the card slot of the peripheral connector match the position, the claw 304 that is squeezed and elastically retracted is reset, thereby realizing the card connection between the protrusion 306 and the card slot.

[0032] A positioning groove 104 is provided on the circumferential side wall of the insulator 1, and an inner concave point 307 is provided on the outer conductor 3, and the inner concave point 307 is clamped with the positioning groove 104. The positioning groove 104 is an annular groove. The inner concave point 307 on the outer conductor 3 is formed by punching after the limiting strip 102 on the insulator 1 and the limiting groove 305 at one end of the outer conductor 3 are correspondingly plugged into place, so that the inner concave point 307 and the positioning groove 104 are clamped, preventing the outer conductor 3 and the insulator 1 from detaching along their axial direction after being sleeved and installed, thereby realizing the assembly and fixation between the insulator 1 and the outer conductor 3.

[0033] A wedge-shaped deformation block 201 is arranged on the circumferential side wall of the middle end of the center needle 2, and a penetrating anti-slip groove 105 is opened on the inner wall of the installation channel 101, and the wedge-shaped deformation block 201 and the anti-slip groove 105 are clamped.

[0034] A clamping piece 202 is symmetrically provided at one end of the center needle 2 away from the cable 4, and a guide block 203 is provided at one end of the clamping piece 202 away from the center needle 2. A retaining ring 106 is provided at one end of the installation channel 101 away from the cable 4, and the retaining ring 106 conflicts with the guide block 203 on the clamping piece 202.

[0035] like Figure 7 As shown, the cross-section of the wedge-shaped deformation block 201 is in the shape of a right-angled triangle. When the center pin 2 is plugged into the installation channel 101 in the insulator 1, the acute-angled end of the wedge-shaped deformation block 201 of the right-angled triangle is first inserted into the installation channel 101. During the insertion process, the inclined surface of the wedge-shaped deformation block 201 is squeezed into the center pin 2 by the inner wall of the installation channel 101 and deformed. The inner diameter of the retaining ring 106 is smaller than the inner diameter of the installation channel 101. When the guide block 203 on the clamping piece 202 contacts the retaining ring 106, the insertion cannot continue. At this time, the wedge-shaped deformation block 201 just reaches the position of the anti-slip groove 105, so that the wedge-shaped deformation block 201 is reset, thereby completing the assembly of the center pin 2 and the insulator 1, and the right-angled side of the wedge-shaped deformation block 201 and the anti-slip groove 105 are clamped together to prevent the center pin 2 from being detached from the insulator 1 when the peripheral connector is inserted.

[0036] Among them, a guide chamfer is set on the side of the retaining ring 106 away from the center pin 2. Through the setting of the guide chamfer, the male pin of the peripheral connector is prevented from being misaligned during insertion, resulting in insertion into the gap between the female pin and the hole.

[0037] Furthermore, the clamping piece 202 is elastically arranged. In the initial state, the end of the clamping piece 202 away from the center pin 2 approaches the center axis. When the connector of the present invention is plugged into the peripheral connector, the communication connector of the peripheral connector will first contact the guide block 203, and then be guided to the axis of the center pin 2 by the guide surface on the guide block 203, so as to be inserted into the center pin 2. After the peripheral connector and the center pin 2 are plugged into each other, the clamping piece 202 will be expanded, and the expanded guide block 203 and the clamping piece 202 will clamp the plugged peripheral connector, thereby improving the performance of the electrical connection.

[0038] The sleeve 5 is divided into an outer conductor crimping section 501, an anti-slip section 502 and a cable crimping section 503, and the inner diameter of the anti-slip section 502 is larger than the inner diameters of the outer conductor crimping section 501 and the cable crimping section 503. An anti-slip opening 308 is provided at one end of the crimping area 303 on the outer conductor 3 away from the assembly area 302, and the anti-slip opening 308 is matched and arranged inside the anti-slip section 502.

[0039] The crimping area 303 on the outer conductor 3 is the connection area between the outer conductor 3 and the cable 4, and a mesh embossing 309 is provided on the outer wall at one end of the crimping area 303. Through the setting of the mesh embossing 309, when the sleeve 5 is crimped, the friction force between the sleeve 5 and the outer conductor 3 is increased, thereby improving the connection performance and further ensuring the stability of the connection between the outer conductor 3 and the cable 4.

[0040] A wire clamp 6 is provided inside the anti-slip section 502 of the sleeve 5 , and one end of the wire clamp 6 abuts against an end of the anti-slip section 502 of the sleeve 5 away from the outer conductor 3 .

[0041] When the sleeve 5 is sleeved and assembled with the outer conductor 3 and the cable 4, the sleeve 5 is a cylindrical tube, and its diameter matches the outer diameter of the anti-slip opening 308. After the sleeve assembly, the two ends of the sleeve 5 are compressed to form an outer conductor crimping section 501 that matches the outer conductor 3 and a cable crimping section 503 that matches the cable 4, so that the sleeve 5 and the outer conductor 3 and the cable 4 are fixedly connected.

[0042] It should be noted that before the cable 4 and the outer conductor 3 are connected, the sleeve 5 and the wire clamp 6 are first sleeved on the cable 4. After the cable 4 and the outer conductor 3 are plugged in, the sleeve 5 is moved and sleeved on the crimping area 303 of the outer conductor 3. When the two ends of the sleeve 5 are crimped, the wire clamp 6 is located in the anti-detachment section 502, which improves the connection performance between the cable 4 and the sleeve 5, thereby improving the connectivity between the cable 4 and the outer conductor 3, and avoiding the movement of the cable 4, which may cause poor contact between the cable 4 and the center pin 2.

[0043] Embodiment 2 is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides an outer conductor drawing process, which is applied to a high-shielding vehicle-mounted connector. S1: Load the copper strip onto the drawing equipment, and perform two copper sheet drawing operations with different punch sizes and punch strokes according to the structure of the matching area 301, thereby completing the drawing of the matching area 301; S2: Based on the structure of the crimping area 303, after the copper sheet of the matching area 301 has been drawn, the copper sheet is drawn twice with different punch sizes and different punch strokes, thereby completing the drawing of the crimping area 303; S3: Based on the structure of the assembly area 302, on the basis of the copper sheets of the matching area 301 and the crimping area that have been drawn, a copper sheet is drawn to match the punch size and punch stroke of the assembly area 302, thereby forming the assembly area; S4: Perform a deep drawing to match the punch size and punch stroke of the crimping area 303, thereby opening the crimping area 303, and then expand one end of the crimping area of ​​the opened outer conductor 3 through the lower die to form an anti-slip opening 308; S5: A limiting groove 305 is formed in the matching area on the deep-drawn outer conductor 3, and a mesh embossing 309 is formed by knurling in the crimping area 303 .

[0044] The rest of the structure is the same as that of Example 1.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
