Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present application based on the embodiments herein.

As described above, the inventors have found in the study of the package that the existing package is generally fixedly connected to the circuit board through the pins, and that the external force applied to the package can be transferred to the pins and, without buffering, to the connection of the pins to the circuit board through the pins. The pins are typically connected to the circuit board by soldering or the like, and during the transfer of external forces from the pins to the circuit board, the external forces may cause the solder to break, thereby damaging the card, e.g., the card may not be able to use the pins disconnected from the circuit board to transfer electrical signals. In addition, the card may be fixedly connected to the circuit board through a plurality of pins, which may have different lengths due to tolerance or over-constraint, etc., so that at least some of the pins may be disconnected from the circuit board due to uneven stress during the process of fixing the pins to the circuit board or during the process of subjecting the card to external force. On the other hand, the sealing between the insert and the shell is usually carried out by applying sealant, and the sealant can fail with the advancement of time, so that the sealing of the insert is failed; in addition, the sealant may also cause difficulty in disassembly, thereby causing problems that are disadvantageous for after-market maintenance.

The utility model will be better explained by the following detailed description of the embodiments with reference to the drawings. References herein to terms such as "upper", "lower", "inner" and "outer" refer to the orientation of FIG. 2. The position of the circuit board 2 with respect to the base plate 12 is defined as "up"; the position of the mating end 32 extending from the card connecting hole 11 with respect to the card body 31 is defined as "outside".

In order to solve the above technical problems, an embodiment of the present application provides an insert, in which an insertion end of the insert is formed by extending from one side of an insert body, and pins extending from an outer side of a housing to an inner side of the housing through the insert body and the insertion end may be fixedly connected to a circuit board. Because the middle part of pin is formed with spiral structure, therefore this spiral structure can transmit the external force that transmits the pin and cushion to reduce the possibility that the junction of pin and circuit board breaks away, improved the damage resistance performance of plug-in components, controller etc..

As shown in fig. 1 to 5, the insert 3 provided in the embodiment of the present application includes: the plug-in connector comprises a plug-in connector body 31 fixedly connected with the shell 1 and a plug-in end 32 penetrating through the plug-in connector hole 11, wherein the plug-in end 32 is formed by extending from one side of the plug-in connector body 31; the plug-in 3 is further provided with a pin 4, one end of the pin 4 is fixedly connected with the circuit board 2, the other end of the pin 4 penetrates through the plug-in main body 31 and the plug-in end 32 to extend to the outer side of the shell 1, and a spiral structure is formed in the middle of the pin 4.

In an exemplary embodiment, the insert 3 may be formed by injection molding. For example, the pins 4 may be placed in an injection mold, and then injection molded based on the injection mold. In this case, the gaps between the pins 4 and the card body 31 and between the pins 4 and the mating ends 32 can be reduced to satisfy waterproof requirements, such as IP67 waterproof requirements. The spiral structure of the pin 4 can be realized with reference to a spiral spring. In a state where the card 3 is assembled to the housing 1, the card body 31 may be located inside the housing 1, and the insertion end 32 passes through the card connection hole 11 and extends to the outside of the housing 1. Accordingly, the pins 4 extend from the inside of the housing 1, through the card body 31 and the mating end 32, and to the outside of the housing 1. The spiral structure of the pins 4 may be located inside the housing 1. The pins 4 may be soldered to the circuit board 2.

It should be appreciated that the spiral structure of the pin 4 may buffer the external force transmitted to the pin 4 to reduce the possibility of the connection between the pin 4 and the circuit board 2 being broken by the external force, so that the damage resistance of the card 3 and the controller or the like provided with the card 3 may be improved. When there are a plurality of pins 4, a tolerance or over-constraint, etc. may cause the lengths of the portions of the plurality of pins 4 located inside the housing 1 to be different. In this case, the external force to which the plurality of pins 4 are subjected will be different. However, since the helical structure of the pins 4 may buffer the external forces, the force of the plurality of pins 4 will be relatively uniform to reduce the likelihood of one or more of the plurality of pins 4 being disconnected from the circuit board 2. It follows that the insert 3 of the exemplary embodiment has relatively high impact resistance.

Further, a sealing strip mounting groove 33 is formed on the side end surface of the plug-in unit body 31, which contacts with the housing 1, and a plug-in sealing strip 5 is disposed in the sealing strip mounting groove 33, and the plug-in unit body 31 is used for pressing the plug-in sealing strip 5 to seal the plug-in unit 3 when the plug-in end 32 is inserted into the plug-in unit connection hole 11.

In the exemplary embodiment, when the plugging end 32 of the plug-in main body 31 is inserted into the plug-in connection hole 11, the plug-in sealing strip 5 arranged in the sealing strip mounting groove 33 can be extruded by the plug-in main body 31, so that water is restricted from entering the inner side of the shell 1 through deformation of the plug-in sealing strip 5, sealing of the plug-in 3 relative to the shell 1 is realized, and the IP67 sealing requirement can be further satisfied. The likelihood of seal failure due to sealant failure is reduced as compared to sealing with a sealant. In addition, since the insert seal 5 is provided in the seal mounting groove 33 and can be separated from the housing 1 together with the insert body 31 when the insert body 31 is separated from the housing 1, the effect of easy disassembly can be achieved, and the after-sales maintenance difficulty can be reduced.

Further, the insert body 31 is provided with a second insert mounting hole 34 corresponding to the first insert mounting hole 14 on the housing 1, and the insert body 31 is fixedly connected with the housing 1 by the first fastener 6 penetrating through the first insert mounting hole 14 and the second insert mounting hole 34.

In an exemplary embodiment, the first fastener 6 may be a bolt. In the mounting process, the alignment between the plugging end 32 and the plug-in connection hole 11 of the housing 1 can be achieved by aligning the first plug-in mounting hole 14 with the second plug-in mounting hole 34, so that the effect of reducing the mounting difficulty can be achieved.

Further, a weather strip mounting groove 33 is provided along the second card mounting hole 34 and the outer periphery of the mating end 32. By providing the seal strip mounting groove 33 along the outer circumferences of the second card mounting hole 34 and the mating end 32, the card seal strip 5 can be correspondingly provided along the outer circumferences of the second card mounting hole 34 and the mating end 32, so that both the second card mounting hole 34 and the mating end 32 can be spaced apart from the space inside the housing 1.

Further, a plurality of second insert mounting holes 34 are provided around the mating end 32. The plurality of second package mounting holes 34 provided around the mating end 32 can share the external force transmitted from the mating end 32 to the package main body 31 during use, and can also make the pressing force of the package main body 31 received by the package sealing tape 5 relatively uniform.

Further, the controller according to another embodiment of the present utility model includes: a shell 1 provided with a plug-in connection hole 11; a circuit board 2 disposed inside the housing 1 and fixedly connected to the housing 1; an insert 3; the plug-in unit 3 is connected with the shell 1 through the plug-in unit connecting hole 11, and the plug-in unit 3 is fixedly connected with the circuit board 2 through the pin 4.

The controller provided in this embodiment has the plug-in unit provided in any one of the embodiments, so that the controller has all the beneficial effects of the plug-in unit provided in any one of the embodiments, and will not be described herein.

Further, the housing 1 includes a bottom plate 12 and side plates 13, and the side plates 13 are formed extending upward from the end surfaces of the bottom plate 12. The bottom panel 12 and the side panels 13 may be at a predetermined angle, for example, an angle between 60 degrees and 120 degrees, such as 90 degrees.

Further, the insert connecting hole 11 is formed in the side plate 13, and the insert body 31 of the insert 3 is fixedly connected to the side plate 13.

In an exemplary embodiment, the card connecting hole 11 and the first card mounting hole 14 may be opened in the side plate 13. Accordingly, by the fixed connection of the insert body 31 and the side plate 13, the insert body 31 presses the insert sealing strip 5 in a direction approaching the side plate 13, thereby realizing the seal between the insert 3 and the side plate 13.

Further, a mounting table 15 is fixedly arranged on the bottom plate 12, and the circuit board 2 is fixedly connected with the bottom plate 12 through the mounting table 15.

It should be understood that, by the mounting table 15, the lower surface of the circuit board 2 fixedly connected to the bottom plate 12 is prevented from directly contacting the bottom plate 12, and a space is reserved for components provided on the lower surface of the circuit board 2.

Further, the circuit board 2 is provided with a first circuit board mounting hole 21, the mounting table 15 is provided with a second circuit board mounting hole 16, and the circuit board 2 is fixedly connected with the mounting table 15 through a second fastener 7 penetrating through the first circuit board mounting hole 21 and the second circuit board mounting hole 16.

It should be noted that the second fastening member 7 may be a bolt; by aligning the first circuit board mounting holes 21 with the second circuit board mounting holes 16, the circuit board 2 can be disposed at a position set in advance on the base plate 12, thereby facilitating the mounting of the circuit board 2 by reducing the time taken to adjust the position of the circuit board 2.
