The present application relates to the technical field of automobile electrical systems, in particular to a crimping terminal, a signal receiving module and electronic equipment.

Background technique

With the rapid development of electric vehicles and automotive communications, it is foreseeable that the development of unmanned driving technology will greatly enrich the future world, adding space for the development of intelligent interconnection to the traditional automotive industry. At that time, vehicles can rely on 5G networks Carry out autonomous driving, which can automatically avoid other vehicles and pedestrians during driving to effectively avoid traffic accidents and improve traffic efficiency.

In order to achieve unmanned driving and communication interconnection, more radar modules need to be added to the car, and its signal processing capability and reliability must be greatly improved. At present, the automotive electrical system is in the state shown in FIG. 2 through the cooperation of the crimping terminal 1 commonly used in the industry and the printed circuit board 2 as shown in FIG. Copper plating layer 211 is coated on the inside of the inner side. When the crimping terminal 1 is pressed into the plating hole 21 and contacts the plating layer 211 to realize electrical connection, the signal received by the signal receiving module can be introduced into the internal electronic circuit of the radar module. The reliability of the connection between the crimp terminal 1 and the plated hole 21 of the printed circuit board 2 directly affects the calculation and processing results of the electronic circuit inside the radar module, and even affects the safety performance of the vehicle.

Referring to FIG. 2 , the cross-section of the crimping terminal 1 perpendicular to the length direction is a rectangle with a rounded apex. When the crimping terminal 1 is pressed into the plated hole 21 of the printed circuit board 2, the plated hole 21 will be squeezed to make the plated hole 21 occur. Deformation, after the plated hole 21 is deformed, reverse pressure is applied to the crimping terminal 1, so that the plated hole 21 of the printed circuit board 2 and the crimping terminal 1 are squeezed to generate friction force so as to realize the crimping terminal 1 and the crimping terminal 21. The plated layer 211 contacts to realize electrical reliable connection. Of course, the degree of deformation of the plated hole 21 needs to be controlled to avoid the situation that the plated layer 211 and the plated hole 21 are damaged. According to the regulations of IEC60352-5, the deformation a of the plated layer 211 of the plated hole 21 in FIG. 2 should be less than 70 μm. And the thickness b of the deformed plating layer 211 is not less than 8 μm (as shown in FIG. 1 ), so as to ensure the reliability of the connection and prevent the plating layer 211 and the plated hole 21 from being damaged.

Due to the complexity and harshness of the application scenarios in the automotive industry, the current crimp terminal 1 cannot meet the requirements of cooperating with the printed circuit board 2 to achieve a reliable electrical connection while maintaining the structural integrity of the plated hole 21 .

Contents of the invention

The present application provides a crimping terminal, a signal receiving module and an electronic device, so as to keep the structural integrity of the plated hole of the printed circuit board under the premise that the crimping terminal and the printed circuit board cooperate to realize reliable electrical connection.

The crimp terminal provided in the present application can be applied to electronic equipment of an automobile electrical system, specifically, it can be arranged in a signal receiving module of the electronic equipment, and serve as a signal output terminal of the signal receiving module. In application, press the crimp terminal and insert it into the plated hole on the printed circuit board of the processing module of the electronic device, so that the crimp terminal and the plating layer in the plated hole are extruded to achieve electrical connection. The friction force generated by mutual extrusion between the holes keeps the electrical connection stable and reliable (the following description only involves the fit between the crimp terminal and the plated hole, ignoring the plating layer). The crimp terminal is formed by bending and curling a continuous metal sheet. Specifically, it can include a contact section, a connecting section and a guide section formed at both ends of the contact section. Of course, the connection between the guide section and the contact section has a smooth transition, and the connection section and the contact section The junctions are also smooth transitions. Wherein, the maximum radial dimension of the contact section is larger than the diameter of the plated hole of the printed circuit board, and when the crimp terminal is inserted into the plated hole of the printed circuit board, the contact section is squeezed into the plated hole. Specific to the structure of the contact section, at least a part of the outer surface of the contact section forms an arc surface, so that when the crimp terminal is crimped and fitted with the printed circuit board, the outer surface of the contact section is pressed and fitted with the inner wall of the plated hole of the printed circuit board . The above-mentioned arc surface has an axis line extending along the arrangement direction of the connecting section, the contact section and the guiding section. The direction is parallel to the axis line of the plated hole, the arc surface formed by the outer surface of the contact section matches the inner wall of the plated hole, and the axis line of the arc surface is collinear with the axis line of the plated hole. The arc surface formed on the outer surface of the contact section is equivalent to the surface fit with the inner wall of the plated hole, and there is a large contact area between the two. The force exerted by the crimp terminal on the plated hole is dispersed, so that the extrusion force per unit area of the plated hole Reduced, and thus the deformation of the plated hole is reduced, which can reduce the degree of damage to the plated hole by the crimping terminal, and ensure the integrity of the plated hole as much as possible. Along the circumferential direction of the axis line of the above-mentioned arc surface, the two sides of the contact section are formed with abutting parts bent toward the axis line of the arc surface; Hole crimp fit, the two abutting parts are extruded by the plated hole until the two abutting parts are in contact. At this time, the two abutting parts are equivalent to two simply supported beams forming the crimped terminal. When the crimped terminal and the printed circuit The plated holes of the board provide support for the entire structure so that the crimp terminal and the printed circuit board maintain a stable and reliable connection; at this time, when the contact section is perpendicular to the arrangement direction of the connection section, contact section and guide section of the crimp terminal In the cross section, the geometric center of the contact section is equivalent to a fulcrum of the crimp terminal, and the abutment point of the two abutting parts is equivalent to the other fulcrum of the crimp terminal. The two fulcrums ensure the structural stability of the crimp terminal, and can also Keep a large friction force between the crimp terminal and the plated hole to meet the reliability of the connection between the crimp terminal and the plated hole.

In a possible implementation manner, in order to facilitate the abutment portion to curl toward the circular axis of the arc surface formed on the outer surface of the contact section, the thickness of each abutment portion is from one end of the abutment portion close to the contact section to the thickness of the abutment portion. The free end (for each abutment portion, the free end refers to the end away from the contact segment) gradually decreases. In order for the two abutting parts to abut more stably and smoothly after being squeezed, the free end of each abutting part may be curved.

Specifically, the guide section of the crimp terminal is to guide the contact section into the plated hole of the printed circuit board so that the contact section and the plated hole are press-fitted, so along the arrangement direction of the guide section, the contact section and the connecting section, the guide section The cross-sectional area of is smaller than the cross-sectional area of the contact segment. In order to optimize the guiding effect of the guide section, the cross-sectional area of the guide section gradually decreases from the end of the guide section close to the contact section to the free end of the guide section (that is, the end of the guide section away from the contact section), so that the guide section is equivalent to A tapered structure (the radial small end of the tapered structure is away from the contact section); during the process of inserting the crimp terminal into the plated hole of the printed circuit board to achieve crimp fit, the free end of the guide section first enters the plated hole and guides The guide section completely passes through the plated hole until the contact section extends into the plated hole and cooperates with the plated hole to realize the electrical connection between the crimp terminal and the printed circuit board. At the junction of the guide section and the contact section, a number of through holes through the crimp terminal can be provided, which can reduce the extrusion force applied by the crimp terminal to the plated hole when the crimp terminal is inserted into the plated hole, thereby Reduce the damage of the crimp terminal to the internal circuit of the printed circuit board.

The connecting section of the crimping terminal is used to connect the external fixing part. The external fixing part can be the signal output end of a signal receiving module. When the connecting section of the crimping terminal is connected with the external fixing part of the signal receiving module, the crimping terminal It can be used as a signal output port of the signal receiving module to cooperate with printed circuit boards of other modules to realize electrical connection.

Detailed ways

Based on the basic structure of the crimp terminal 1 shown in FIG. 1 , a common crimp terminal 1a with a hollow structure is shown in FIG. 3 . A hollow can be formed in the middle part M of the crimp terminal 1a. The cross-sectional structure at A-A shown in Fig. 3 is shown in Fig. 4a). Combining the mating form of the crimping terminal 1 and the printed circuit board 2 shown in FIG. 2 , in order to increase the frictional force for maintaining reliable connection when the crimping terminal 1a is mated with the plated hole 21 of the printed circuit board 2 , it can be shown in FIG. 4a The hollow area M of the crimping terminal 1a shown is simply supported Z to transition to the crimping terminal 1b of a solid structure (the appearance of this crimping terminal 1b is similar to that of the crimping terminal 1a shown in FIG. 3 , here The schematic diagram of its outline structure is omitted, and only the cross-sectional schematic diagram of the hollow area M of the crimp terminal 1b is shown in Fig. 4b and Fig. 4c), so as to obtain a larger holding force; however, compared with the The crimping terminal 1a, the crimping terminal 1b of solid structure shown in FIG. 4b and FIG. 4c are used to extrude the outer contour of the plated hole 21. The outer contours are all rectangular and rounded, and have not changed. The contact area with the inner wall of the plated hole 21 There will be no change, but the crimping terminal 1b with a solid structure will exert a greater pressing force on the plated hole 21, and the damage to the plated hole 21 will be aggravated, and the connection requirements may not be met. As shown in FIG. 4 d , the cross-sectional schematic diagram of the cooperation structure between the crimping terminal 1c of the C-shaped structure and the plated hole 21 of the printed circuit board 2, the friction force generated by extrusion between the crimping terminal 1c and the plated hole 21 Only relying on the elastic force generated by the deformation of the crimping terminal 1c itself cannot meet the application scenarios with relatively harsh vibrations, and risks such as loosening and falling off are prone to occur, the connection reliability is low, and there is a possibility of functional failure.

It can be seen that none of the above-mentioned crimp terminals 1a, 1b, and 1c can meet the electrical connection requirements of the automotive industry with complex application environments. Therefore, the embodiment of the present application provides a crimp terminal 10 as shown in FIG. On the premise of keeping the structural integrity of the printed circuit board 2 (the cooperation between the crimping terminal 10 and the printed circuit board 2 is not shown in FIG. 5 ). Specifically, FIG. 5 shows the three-dimensional structure of the crimp terminal 10 provided by the embodiment of the present application. The crimp terminal 10 is formed by bending and curling a continuous metal sheet, and includes a guide section 11 and a contact section 12 along its length direction. And the connection section 13, of course, the guide section 11 and the contact section 12 have a smooth transition, and the connection section 13 and the contact section 12 also have a smooth transition. It is set here that the arrangement direction of the guide section 11 , the contact section 12 and the connection section 13 is the length direction of the crimp terminal 10 .

Fig. 6 shows the schematic diagram of the process of cooperating the crimp terminal 10 shown in Fig. 5 with the plated hole 21 of the printed circuit board 2, along the direction of the arrow shown in Fig. The plated hole 21 makes the contact section 12 contact with the inner side of the plated hole 21, where the diameter of the contact section 12 is greater than the diameter of the plated hole 21, when the contact section 12 enters the plated hole 21, the contact section 12 is interference fit with the plated hole 21, and the contact section 12 squeezes the plated hole 21 to generate a frictional force between the two, and this frictional force can keep the electrical fit between the crimping terminal 10 and the printed circuit board 2 stable and reliable. It can be understood that since the crimp terminal 10 in this embodiment is formed plastically from a continuous sheet metal, the surface roughness of the contact section 12 can be controlled in the sheet metal rolling process to obtain a lower roughness. The section 12 is press-fitted with the plated hole 21 of the printed circuit board 2, and the contact section 12 of the crimped terminal 10 is used to match the roughness of the contact surface of the plated hole 21, which can be reduced to that of the crimped terminal 1 with a common solid structure (as shown in Fig. The crimping terminal 1b shown in 4b or the crimping terminal 1c) shown in FIG.

Referring to Fig. 5 and Fig. 6, the guide section 11 is in order to guide the contact section 12 into the plated hole 21 of the printed circuit board 2, the guide section 11 needs to pass through the plated hole 21 smoothly, so along the length direction perpendicular to the contact section 12, The cross-sectional area of the guide section 11 needs to be smaller than the cross-sectional area of the contact section 12; in the structure of the crimp terminal 10 shown in Figure 5 and Figure 6, the guide section 11 has a tapered structure, and the cross-sectional area of the guide section 11 is used for connecting From one end of the contact section 12 to the free end (ie, the end of the guide section 11 away from the contact section 12 ) gradually decreases.

Figure 7 shows a possible structure of the crimp terminal 10, in which a through hole 14 through the crimp terminal 10 can be opened at the junction of the guide section 11 and the contact section 12 (the number of through holes 14 is not limited, Fig. 7 shows that the crimp terminal 10 is symmetrically provided with two through-holes 14 with respect to the length direction, and only one of the through-holes 14 is shown in FIG. 7 due to limited viewing angle). During the process of inserting the crimp terminal 10 into the plated hole 21 of the printed circuit board 2, the guide section 11 first enters the plated hole 21, and when the junction of the guide section 11 and the contact section 12 enters the plated hole 21, these through holes 14 can be reduced. The extrusion force applied to the plated hole 21 when the small crimp terminal 10 is inserted into the plated hole 21 of the printed circuit board 2 can reduce damage to the internal circuit of the printed circuit board 2 by the crimped terminal 10 .

Fig. 8 shows the front view of the crimp terminal 10 shown in Fig. 7, the sectional view of the crimp terminal 10 shown in Fig. 9 is obtained according to the section A-A in Fig. 8, and the section B-B is in the contact section 12, therefore, Fig. 8 The cross section in is also the cross section of the contact segment 12 perpendicular to the length direction of the crimp terminal 10 . Referring to FIG. 9, at least a part of the outer surface of the contact section 12 forms an arc surface K, which extends along the length direction of the crimp terminal 10 and has an axis line parallel to the direction of the length of the crimp terminal 10. The central angle α corresponding to the axis line of the surface K is within the range of 220°±5° (Figure 9 shows the case where the central angle α corresponding to the arc surface K is 220°); when the crimp terminal 10 and the printed circuit board 2 plated hole 21, and the arc surface K is used to cooperate with the inner wall of the plated hole 21. Along the circumferential direction of the axis of the arc surface K, both sides of the contact segment 12 are formed with abutting portions 121a, 121b that bend in the direction of the axis of the arc surface K (center O shown in FIG. 9 ). The distance between the free end of the abutting portion 121a and the free end of the abutting portion 121b is close, so that when the crimp terminal 10 is inserted into the plated hole 21 of the printed circuit board 2, the free end of the abutting portion 121a is free from the free end of the abutting portion 121b. End contact offset. When the contact section 12 of the crimp terminal 10 is press-fitted with the plated hole 21 of the printed circuit board 2, the cross-sectional structure schematic diagram when the contact section 12 is matched with the plated hole 21 shown in Figure 10 is obtained in combination with the view angle shown in Figure 9 ( The printed circuit board 2 is omitted in Fig. 10, and the plated hole 21 is shown in the form of a solid structure), the arc surface K formed on the outer surface of the contact section 12 and the inner wall of the plated hole 21 realize a surface fit with a larger contact area, crimping The force exerted by the terminal 10 on the plated hole 21 is evenly dispersed, and the extrusion force per unit area of the plated hole 21 is reduced, and the deformation of the plated hole 21 is also reduced accordingly, thereby reducing the pressure on the crimped terminal 10. The degree of damage to the plated hole 21 ensures the integrity of the plated hole 21 as much as possible. The contact area between the crimp terminal 10 and the plated hole 21 of the printed circuit board 2 here is equivalent to that of a crimp terminal 1 with a common solid structure. (The crimp terminal 1b shown in FIG. 4b or the crimp terminal 1c shown in FIG. 4c) is 4 times the contact area with the plated hole 21 of the printed circuit board 2; at the same time, the abutment portion 121b and the abutment portion 121a are respectively Curl in the direction of the arc surface K-axis until the abutting portion 121b abuts against the abutting portion 121a. At this time, the abutting portion 121b and the abutting portion 121a are equivalent to two simply supported beams of the crimping terminal 10, and provide support for the entire structure when the crimping terminal 10 is mated with the plated hole 21 of the printed circuit board 2, thereby improving the crimping performance. The friction between the terminal 10 and the plated hole 21 of the printed circuit board 2 makes the crimp terminal 10 and the printed circuit board 2 maintain a stable and reliable connection.

Please continue to refer to the schematic diagram of the sectional structure when the contact section 12 cooperates with the plated hole 21 shown in Figure 10, the geometric center Q1 of the contact section 12 is equivalent to a fulcrum of the crimp terminal 10; The free ends of the crimping terminal 10 are equivalent to two simply supported beams of the crimping terminal 10, and the contact point Q2 between the two is equivalent to another fulcrum of the contact section 12; the two fulcrums ensure the structural stability of the crimping terminal 10, and also A large frictional force is maintained between the crimping terminal 10 and the plated hole 21 to meet the reliability of the connection between the crimping terminal 10 and the plated hole 21 .
