120 and 140. The first terminal 120 and the second terminal 140 can be firmly contact-connected to each other by the fixation and support of the terminal fixing portion 160. The connection between the first terminal 120 and the first electronic component 110 or the second terminal 140 and the second electronic component 130 may include a direct fixed contact connection or an indirect connection through a wire. As shown in fig. 4, the second terminal 140 may be directly fixedly connected to the control portion 13 and connected in contact with the first terminal 120; the first terminal 120 is fixed to the functional part 11 by the terminal fixing part 160 and is indirectly connected to the functional part 11 by a lead wire. This example is described in detail below.

As shown in fig. 8, the first terminal 120 is formed in a hollow rectangular parallelepiped columnar structure having a first end 121 and a second end 122 opposite to each other.

The first end 121 is an end of the first terminal 120 indirectly connected to the functional portion 11 by a wire or the like. The second end 122 is disposed on the opposite side of the first end 121 for contact connection with the second terminal 140 to form an electrical connection. The first end 121 and the second end 122 are formed in a rectangular shape. Referring to fig. 8, an upper end of the first terminal 120 is formed as a first end 121 and a lower end of the first terminal 120 is formed as a second end 122. The first end 121 is provided with a boss 123. The projection 123 is a flat plate shape extending perpendicularly outward from a specific position of the outer circumference of the first end 121, and includes a first face 123-1 and a second face 123-2 opposite to each other with respect to the longitudinal direction. The longitudinal direction includes a direction from the first end to the second end, or a direction from the second end to the first end.

The main body 161 is provided with an accommodating space 163 accommodating the first terminal 120. Specifically, the receiving space 163 may be formed by the terminal fixing sidewall 162 extending longitudinally perpendicular to the fixing portion bottom surface 161-1 of the body 161. For example, a through hole may be formed on the fixing portion bottom surface 161-1 of the body 161, and a terminal fixing sidewall 162 may be formed at an edge of the through hole to extend vertically to the fixing portion bottom surface 161-1 of the body 161, and a space formed by the terminal fixing sidewall 162 is a receiving space 163 for receiving the first terminal 120. Opposite ends of the receiving space 163 form an insertion port 163-1 and a penetration port 163-2. The exit 163-2 is closer to the second terminal 140. Referring to fig. 9, the upper end of the terminal-fixing sidewall 162 extending in the longitudinal direction forms an insertion opening 163-1 and the lower end thereof forms a penetration opening 163-2. When the first terminal 120 is assembled into the accommodating space 163, the second end 122 of the first terminal 120 enters the accommodating space 163 from the insertion port 163-1.

The insertion port 163 is provided with an insertion port guide surface 164 inclined from the outer periphery to the inner periphery and toward the insertion port 163-2. The insertion port guide surface 164 may facilitate the insertion of the first terminal 120 into the receiving space 163.

As described above, boss 123 extends perpendicularly outwardly from first end 121 of first terminal 120 to extend out of insertion opening 163-1. That is, in the mounted state, the second end 122 of the first terminal 120 enters the accommodating space 163 from the insertion port 163-1 and enters the accommodating space 163 in the longitudinal direction until the second end 122 passes out of the accommodating space 163 from the passing-through port 163-2 with the first end 121 located in the vicinity of the insertion port 163-1 and the projection 123 is caught on the terminal fixing side wall 162 around the insertion port 163-1 to restrict the first terminal 120 from continuing downward in the longitudinal direction, thereby fixing and supporting the first terminal 120.

Specifically, as shown in fig. 10, the lateral width of first terminal 120 including projection 123, i.e., the distance L1 from projection outer peripheral surface 123-3 of projection 123 to the opposite side, is larger than the width L2 of the corresponding position of insertion port 163-1 so that projection 123 can be fitted to insertion port 163-1 in the mounted state.

The terminal fixing portion 160 may further include a rib 165. Rib 165 protrudes from a part of the outer periphery of insertion port 163-1 in the longitudinal direction in the opposite direction to outlet port 163-2, and has a top surface farther from outlet port 163-2 than insertion port 163-1. In the mounted state, the predetermined positional relationship between the ribs 165 and the bosses 123, which can be used to identify the mounting direction of the first terminals 120, enables the mounting direction of the first terminals 120 to be quickly determined for proper contact connection with the second terminals 140. In the case where the bosses 123 are provided directly above the notches 124 that identify the contact-connection positions with the second terminals 140 as described above, the ribs 165 may be located on the opposite side or adjacent side of the bosses 123. As an example, the ribs 165 may be located on the opposite side of the bosses 123 as shown in fig. 9. When the first terminal 120 is mounted, the first terminal 120 is inserted into the accommodating space 163 from the insertion opening 163-1 in the direction in which the projection 123 is opposite to the projection 165 by the position of the projection 165 and the position of the projection 123 on the first terminal 120, so that the second end 122 of the first terminal 120 is just in contact connection with the second terminal 140, and therefore, the mounting direction of the first terminal 120 can be quickly determined by the projection 165 and the projection 123, facilitating mounting and assembling.

Specifically, the first terminal 120 is a female terminal and is a metal sheet with hooks on both sides, and the second terminal 140 is a male terminal and is a flat plate-shaped insert. During installation, the inserting piece at the male end is inserted into the hook at the female end, so that the inserting piece is in close contact with the metal sheet to be connected and electrically connected. Therefore, when the installation direction is correct, the male end and the female end are parallel. Otherwise, the male end and the female end are in an intersecting state. Specifically, in the case where the cross section of the first terminal 120 is rectangular and the long side of the rectangle is parallel to the blades, when the first terminal 120 and the second terminal 140 are rotated 90 degrees from each other, the blades of the second terminal 140 cannot be inserted into the hook insertion ports of the first terminal 120. Further, since only one side of the first terminal 120 can sandwich the second terminal 140, the second terminal 140 cannot be inserted even when the first terminal 120 is turned over by 180 degrees, and the first terminal 120 and the second terminal 140 cannot be electrically connected. Therefore, the proper mounting direction of the first terminal 120 is ensured by the predetermined positional relationship of the

ribs

123 and 165 on the first terminal 120 to achieve the electrical connection with the second terminal 140.

In the mounted state, the second terminal 140 is disposed opposite to the receiving space 163 of the terminal fixing portion 160. That is, at least a part of the second terminal 140 can be seen when viewed from the insertion opening 163-1 to the insertion opening 163-2 of the accommodation space 163 of the terminal fixing portion 160. The second terminal 140 is disposed adjacent to the first terminal 120, i.e., the second terminal 140 is adjacent to the first terminal 120 with no other components therebetween, and the second terminal 140 is directly connected in contact with the first terminal 120.

The electrical connection structure 100 according to the present invention may further include a covering portion 166.

As shown in fig. 10, the covering portion 166 is for covering the insertion port 163-1 on the terminal fixing portion 160. In the mounted state, the first end 121 of the first terminal 120 is located between the insertion port 163-1 and the covering portion 166. The longitudinal distance L3 between the cover 166 and the rib 165 is less than the longitudinal thickness L4 of the boss 123. That is, the longitudinal distance L3 between the cover 166 and the top surface of the rib 165 is less than the longitudinal distance L4 between the first face 123-1 and the second face 123-2 of the boss 123.

In the present embodiment, the covering portion 166 is provided on the functional bracket 111 of the functional portion 11, specifically, is integrally molded with the bracket top surface 115 of the functional bracket 111.

The utility model also provides an use above-mentioned electric connection structure's air supply arrangement 10. The air blowing device 10 includes the housing 101, at least one function unit 11, a control unit 13, and an air blowing unit 15 as described above. The terminal fixing part 160 of the electrical connection structure 100 according to the present invention is integrally formed with the functional part 11, and the functional part 11 and the control part 13 are electrically connected to each other through the electrical connection structure 100 according to the present invention. The terminal fixing portion 160 is formed integrally with the functional portion 11, and the first terminal 120 is fixed to the terminal fixing portion 160 so as to be formed integrally, and can be electrically connected to the control portion 13 as an integral module. And the first terminal 120 is directly connected in contact with the second terminal 140 fixed to the control part 13, thereby avoiding inconvenience due to wire connection.

In addition, the blower device 10 may further include a stopper structure 102 for positioning the functional unit 11 with respect to the control unit 13 when the functional unit is mounted in the housing 101. As shown in fig. 11, the position limiting structure 102 includes: a stopper wall 12 provided on the housing 101 and having a stopper face 12-1 facing the terminal fixing part 160 of the electrical connection structure 100; and a guide rib 14 extending perpendicularly outward from the outer peripheral surface of the terminal fixing portion and forming an end surface 14-1 interacting with the stopper surface 12-1 at an extended end, which is an end point at which the guide rib 14 extends, i.e., an end portion near the stopper wall 12.

As an example, the guide rib 14 may be formed in a plate-like structure extending laterally outward from the outer peripheral surface of the terminal fixing portion 160. The end face 14-1 of the guide rib 14 includes a click face 14-10 extending in the longitudinal direction from the insertion port 163-1 toward the outlet port 163-2 and a guide face 14-20 continuing from the click face 14-10 toward the outlet port 163-2 while inclining inward. Referring to fig. 11, the engaging surface 14-10 has a straight edge extending in the longitudinal direction, and the guide surface 14-20 has an oblique line inclined in the longitudinal direction toward the outlet 163-2 and away from the stopper surface 12-1.

In the present embodiment, the guide rib 14 is provided on the terminal fixing portion 160, protrudes outward from the outer peripheral surface of the terminal fixing portion 160 integrally formed with the functional portion 11, and has an end surface 14-1 that is further outward than the outer peripheral surface. The engaging surface 14-10 and the guiding surface 14-20 are both located on the end surface 14-1. That is, the guide rib 14 protrudes and extends outward from the fixing portion side wall 161-2 of the terminal fixing portion 160 integrally formed with the functional portion 11. Further, in the direction from insertion port 163-1 to insertion port 163-2, engaging surface 14-10 is farther from insertion port 163-2 than guide surface 14-20.

When the functional part 11 is installed in the longitudinal direction, the guide surface 14-20 first contacts the stopper surface 12-1, and the functional part 11 can be easily moved downward by the inclination of the guide surface 14-20. As the longitudinal installation of the functional part 11 continues, the engaging face 14-10 comes into contact with the stopper face 12-1 to engage the installation of the functional part 11 in the lateral direction.

In the present embodiment, the air blowing device 10 includes a plurality of guide ribs 14 and a stopper wall 12. The stopper wall 12 is provided on the housing 101 or the blower 15, and in the mounted state, is engaged with the guide rib 14 in contact therewith, and the stopper wall 12 and the guide rib 14 form a T-shape as viewed from the insertion opening 163-1 toward the insertion opening 163-2.

In addition to the structure described in the present embodiment, in order to achieve the same effect, the guide rib 14 may be formed to protrude from a member other than the functional portion such as the housing 101 or the blowing portion 15 toward the functional portion 11, and in this case, the guide surface 14-20 is farther from the inlet/outlet 163-2 than the engaging surface 14-10. Accordingly, when the guide rib 14 is provided on a member other than the functional portion 11, the stopper wall 12 that engages with the guide rib 14 is provided on the functional portion 11, for example, constituting a part of the outer peripheral surface of the functional portion 11.

Specifically, the guide rib is provided on the housing 101 and has an end face that guides the functional part 11 to be mounted into the housing 101, and the stopper wall is provided on the functional part 11 and has a stopper face facing the end face, the end face including an engaging face that extends from the outlet 163-2 in the direction of the insertion port 163-1 and a guide face that continues from the engaging face to the insertion port 163-1 and is inclined in a direction away from the functional part 11.

The structure of the embodiment of the present invention is explained above, and the following describes the assembly process.

In this embodiment, when the blower device 10 is assembled, the first terminal 120 is first fixed to the functional unit 11 by the terminal fixing portion 160, and the functional unit 11 is then mounted in the housing 101, so that the first terminal 120 and the second terminal 140 are brought into contact with each other.

First, the second end 122 of the first terminal 120 is inserted into the insertion port 163-1 of the terminal fixing portion 160 in a direction in which the boss 123 and the rib 165 are opposite to each other, and is pushed toward the insertion port 163-2 along the terminal fixing sidewall 162 of the terminal fixing portion 160. The second end 122 of the first terminal 120 will be guided by the terminal holding sidewall 162 to move toward the outlet 163-2. Thereby, the second end 122 of the first terminal 120 enters the receiving space 163 of the terminal fixing part 160. Since the first end 122 of the first terminal 120 is provided with the projection 123 and the projection 123 protrudes and extends outward from the outer circumference of the first end 121 of the first terminal 120, as the second end 122 of the first terminal 120 moves toward the insertion opening 163-2, the projection 123 on the first end 121 also moves toward the insertion opening 163-2, the distance between the projection 123 and the insertion opening 163-1, that is, the distance between the projection 123 and the terminal fixing sidewall 162 around the insertion opening 163-1 becomes smaller, and when the first surface 123-1 of the projection 123 contacts the terminal fixing sidewall 162 around the insertion opening 163-1, the projection will interfere with the terminal fixing sidewall 162 and cannot move to the side of the insertion opening 163-2 any more, at this time, the first end 121 of the first terminal 120 is caught on the insertion opening 163-1 and the second end 122 has already passed through the insertion opening 163-2. Accordingly, the movement of the first terminal 120 in the direction from the insertion port 163-1 to the insertion port 163-2 is restricted, thereby preventing the first end 121 of the first terminal 120 from penetrating through the accommodation space 163 and being not fixed to the terminal fixing portion 160, and achieving the fixing and supporting functions of the first terminal 120.

Since the first terminal 120 is fixed to the terminal fixing portion 160, when the functional portion 11 is mounted inside the housing 101, the first terminal 120 is prevented from moving inside the housing 101 and interfering with other components, thereby preventing the first terminal 120 from being damaged and improving the mounting efficiency.

In addition, a rib 165 is provided on one end of the terminal fixing side wall 162 of the terminal fixing portion 160 at the insertion port 163-1. When the first terminal 120 is inserted into the receiving space 163 through the insertion opening 163-1, if one side of the first end 121 of the first terminal 120 on which the projection 123 is provided corresponds to one side of the terminal fixing sidewall 162 on which the projection 165 is provided, the distance between the projection 123 and the projection 165 becomes smaller as the second end 122 of the first terminal 120 moves toward the insertion opening 163-2, and when the first surface 123-1 of the projection 123 contacts the top surface of the projection 165, the projection 123 cannot move further toward the insertion opening 163-2. At this time, the second end 122 of the first terminal 120 may not be in contact with the second terminal 140.

Therefore, when the first terminal 120 is mounted and the side of the first end 121 of the first terminal 120 on which the projection 123 is provided is opposed to the side of the terminal fixing side wall 162 on which the projection 165 is provided, the first surface 123-1 of the projection 123 can be brought into contact with the end of the terminal fixing side wall 162 located at the insertion port 163-1, and the second end 122 of the first terminal 120 can be brought into contact with the second terminal 140. This prevents the functional unit 11 and the control unit 13 from being disconnected due to an erroneous attachment direction of the first terminal 120.

Further, in the present embodiment, the air blowing device 10 further includes a covering portion 166 for covering the insertion port 163-1 on the terminal fixing portion 160, and the distance between the covering portion 166 and the top surface of the rib 165 on the terminal fixing portion 160 in the mounted state is smaller than the thickness of the boss 123. When the first terminal 120 is mounted in the wrong mounting direction, for example, when the bosses 123 correspond to the ribs 165, the first faces 123-1 of the bosses 123 contact the top faces of the ribs 165, and the covering portions 166 contact the second faces 123-2 of the bosses 123, and the distance between the covering portions 166 and the top faces of the ribs 165 is equal to the thickness of the bosses 123, which is increased from the normal mounting state, which may cause a gap between the covering portions 166 and the terminal fixing portions 160. This prevents the functional unit 11 and the control unit 13 from being disconnected due to an erroneous mounting direction of the first terminal 120.

After the first terminal 120 is fixed to the terminal fixing portion 160, the functional portion 11 is push-fitted into the inside from the fitting opening 101-6 of the housing 101 simultaneously with the first terminal 120. Specifically, the functional portion 11 moves in the longitudinal direction. The fixing portion side wall 161-2 formed integrally with the bracket side wall of the function bracket 111 of the function portion 11 is provided with a guide rib 14 extending outward on the outer peripheral surface thereof, and the guide rib 14 is provided with an inclined guide surface 14-20. The engaging surface 14-10 is disposed farther from the outlet 163-2 than the guide surface 14-20. The case 101 or the air blowing part 15 is provided with a stopper wall 12 facing the guide rib 14. When the functional part 11 moves in the longitudinal direction, the guide surface 14-20 contacts with one end of the stopper surface 12-1 on the stopper wall 12 first relative to the engaging surface 14-10, and at this time, the functional part 11 moves obliquely under the guide of the guide surface 14-20, whereby the accuracy and convenience of mounting the functional part 11 can be improved. The functional part 11 is guided by the guide surface 14-20 to move toward the side of the outlet 163-2 until the stopper surface 12-1 comes into contact with the engaging surface 14-10. At this time, since the contact area between the stopper wall 12 and the guide rib 14 increases, the frictional force increases, and the functional unit 11 can be fixed inside the housing 101, so that the movement of the functional unit 11 is suppressed, and the disconnection of the first terminal 120 and the second terminal 140 due to the looseness of the functional unit 11 can be prevented.

When the engaging surface 14-10 of the guiding rib 14 is completely contacted with the limiting surface 12-1, since the second terminal 140 is disposed opposite to the through hole 163-2 of the terminal fixing portion 160 and the second terminal 140 is disposed adjacent to the second end 122 of the first terminal 120, when the functional portion 11 is moved and fixed to the inside of the housing 101, the second end 122 of the first terminal 120 will be contacted with the second terminal 140, thereby forming an electrical connection. Accordingly, the electric power of the control unit 13 can be transmitted to the first terminal 120 through the second terminal 140, and further transmitted to the function unit 11, so that the electric power is supplied to the function unit 11 to control the operation of the function unit 11.

The above is a description of the process of attaching and connecting the function unit 11 and the control unit 13.

To sum up, the utility model discloses in provide an electric connection structure and applied this electric connection structure's air supply arrangement convenient to connection function portion and control part. This can improve the efficiency of assembly and mounting. Even more, since the first terminal is fixed on the functional portion, the installation of the functional portion can be adapted to modern production such as automated production, and the efficiency of installation production is further improved.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
