Description

Technical Field

[0001] This utility model relates to the field of motor socket technology, and in particular to the structure of motor socket housing. Background Technology

[0002] As the core actuator of the automotive engine idle speed control system, the idle speed motor adjusts the intake air volume by driving the valve core with a motor to precisely maintain the engine idle speed. The motor socket housing is the key interface component for realizing the signal and power transmission between the motor and the vehicle ECU (electronic control unit), which is directly related to the response speed and accuracy of idle speed control.

[0003] Existing motor socket housings consist of a main body base and conductive pin assemblies. The current defects of motor socket housings used in idle speed motors are that the pins and the main body of the existing socket housings are mostly integrally molded, and the motor socket housing part is also integrally molded. This makes it difficult to replace the pins individually when they wear out or deform after long-term use, or when poor contact causes signal transmission failure. Instead, the entire housing must be scrapped and replaced with a new one, which increases maintenance costs and causes unnecessary material waste. Moreover, the replacement process requires disassembling and reassembling the entire housing and other components of the idle speed motor, further extending the maintenance time.

[0004] Furthermore, this one-piece molded structure makes it difficult to flexibly adjust the housing to avoid assembly interference with components such as coils and transmission mechanisms when facing the compact internal space of the idle speed motor. This often requires additional grinding and cutting of the housing edges, which not only compromises the structural integrity and original sealing performance of the housing, allowing contaminants such as oil and moisture to more easily penetrate and affecting the motor's lifespan, but also, the rigid connection between the pins and the main body base caused by the one-piece molding will concentrate vibration stress at the pin roots under the high-frequency vibration of the idle speed motor during operation. Over time, this can easily lead to pin breakage or loosening, affecting signal transmission stability. Therefore, a new motor socket housing structure needs to be designed.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0006] This utility model provides a motor socket housing structure to solve the problem that existing idle speed motor socket housings are integrally formed with the main body and housing, requiring the entire housing to be replaced if the pins fail, which increases costs, wastes materials, and prolongs maintenance time.

[0007] The present invention adopts the following technical solution: a motor socket housing structure, mainly including a socket housing one and a socket housing two that are mutually pluggable and compatible. The socket housing two has an integrally fixed conductive pin. The socket housing two is composed of a bottom platform with an annular structure set at the top and bottom and a concave boss. The socket housing one and the socket housing two are provided with a mating part to enhance the connection strength between the socket housing one and the socket housing two.

[0008] Furthermore, the mating part includes an inner groove at the bottom of the socket housing one that nests with the socket housing two. The inner groove matches the shape of the socket housing two to achieve initial positioning and shorten the assembly time. Two sets of symmetrical plugs extend upward from the base platform, and slots adapted to the plugs are provided on the bottom surface of the socket housing one.

[0009] Furthermore, the socket housing has a protrusion extending downwards on one bottom surface, and a notch adapted to the protrusion is provided on the base platform.

[0010] Furthermore, the boss extends upward with a protruding block, and a recessed groove adapted to the protruding block is provided on the socket housing.

[0011] Furthermore, a limiting ring with a notch is fixed inside the boss, and the limiting ring has a receiving groove at its center, which is used to provide installation and positioning space for the idle speed motor shaft.

[0012] Furthermore, the bottom surface of the base platform is provided with an annular groove, and the annular structure of the groove is adapted to the shape of the coil frame.

[0013] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0014] The motor socket housing structure is designed with two interlocking socket housings, Socket Housing 1 and Socket Housing 2, in which the conductive pins are integrally fixed to Socket Housing 2. When the pins experience wear, deformation, or poor contact, Socket Housing 2 can be disassembled and replaced separately, eliminating the need to scrap the entire housing, thus reducing maintenance costs and material waste. Simultaneously, this split structure, combined with the mating section, enhances connection strength. When replacing pin-related components, only Socket Housing 2 needs to be disassembled, without dismantling the overall connection between the housing and other components of the idle speed motor, shortening maintenance time and improving maintenance efficiency. Socket Housing 2 consists of a base and a concave boss, and the design of the mating section ensures the overall stability of the housing connection, adapting to the vibration environment of the idle speed motor, while the split structure retains assembly flexibility, balancing structural reliability and maintenance convenience.

[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0023] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0024] Reference Figures 1-3 As shown, the motor socket housing structure provided in this embodiment of the utility model includes a socket housing 1 and a socket housing 2 that are plugged into each other and adapted to each other. The two are connected to form a complete housing, which can be adapted to the compact space inside the idle motor. A conductive pin 3 is integrally fixed through the socket housing 2. The conductive pin 3 can stably realize the transmission of signals and power between the motor and the outside. Since it is fixed on the detachable socket housing 2, it is easy to replace it individually in the future.

[0025] Among them, the socket housing 1 is a semi-cylindrical structure. This shape can reduce spatial interference with the internal coil and transmission mechanism of the idle speed motor. The socket housing 2 consists of a bottom platform 21 with an annular structure set at the top and bottom and a concave boss 22. The bottom platform 21 can increase the contact area between the socket housing 2 and other components and improve the overall installation stability. The boss 22 can better nest with the inner groove 11 of the socket housing 1.

[0026] Furthermore, a mating part is provided on the socket housing 1 and the socket housing 2. The mating part includes an inner groove 11 that is nested in the socket housing 2 at the bottom of the socket housing 1. The inner groove 11 matches the shape of the socket housing 2, achieving initial positioning and shortening the assembly time. Two sets of symmetrical plugs 24 extend upward on the base 21. At the same time, a slot 13 that is adapted to the plugs 24 is provided on the bottom surface of the socket housing 1. After the plugs 24 are inserted into the slots 13, the relative sliding of the two in the horizontal direction can be restricted, further improving the connection strength.

[0027] Furthermore, a protrusion 14 extends downward from the bottom surface of the socket housing 1, and a notch (not shown in the figure) is provided on the base 21 to fit the protrusion 14. Figure 1 As can be seen, the protrusion 14 fits the notch outline of the base 21. The protrusion 14 can enhance the structural strength of the socket housing 1. After the protrusion 14 is inserted into the notch, it can prevent the socket housing 1 and the socket housing 2 from rotating relative to each other due to vibration during operation. Through the nesting of the inner groove 11, the cooperation of the plug 24 and the slot 13, and the alignment of the protrusion 14 and the notch, multiple sets of docking structures work together to make the socket housing 1 and the socket housing 2 form a stable whole. It can resist the vibration of the idle motor during operation, prevent the conductive pin 3 from being damaged due to the loosening of the housing, and at the same time ensure the sealing performance of the housing, reduce the intrusion of oil and water, and extend the service life.

[0028] Furthermore, a protruding block 23 extends upward from the boss 22, and a recessed groove 12 adapted to the protruding block 23 is provided on the socket housing 1. During the insertion process, the protruding block 23 can restrict the relative sliding of the two in the horizontal direction by using its own shape and corresponding structure to cooperate. The recessed groove 12 is designed according to the shape of the protruding block 23, and the two form a convex-concave fit. This not only makes the insertion action smoother and the positioning more accurate, but also, after the insertion is completed, the convex-concave structure can resist the vibration generated by the idle motor operation by means of the interlocking, prevent the housing from loosening or separating, ensure the reliability of the conductive pin 3 connection, and thus stably maintain the electrical performance of the motor socket.

[0029] Furthermore, a limiting ring 25 with a notch is fixed inside the boss 22. Its annular outline and notch shape can be observed from the figure. The limiting ring 25 has a receiving groove 251 in the center. The size and shape of the receiving groove 251 are adapted to the idle speed motor shaft. Its function is to provide a precise installation positioning space for the shaft, so that the shaft can maintain coaxiality during operation and avoid abnormal idle speed control due to installation misalignment. At the same time, an annular groove 26 is opened on the bottom surface of the base 21. The annular structure of the annular groove 26 is adapted to the shape of the coil frame and is used to install the coil frame, which can organize the coil arrangement.

[0030] Working Principle: During the assembly stage, firstly, the boss 22 of socket housing 2 is aligned with the inner groove 11 at the bottom of socket housing 1. The concave design of the boss 22 forms a preliminary nest with the inner groove 11, achieving pre-positioning. At this time, the two sets of symmetrical inserts 24 on the base 21 are aligned with the slots 13 on the bottom surface of socket housing 1, and the protrusions 23 and the recesses 12 are also in corresponding positions. As the insertion action continues, the inserts 24 are inserted into the slots 13, the protrusions 23 are embedded in the recesses 12, and at the same time, the protrusions 14 of socket housing 1 engage with the notches of the base 21. Multiple structures restrict the relative displacement of socket housing 1 and socket housing 2 from different directions, making them form a stable whole. During this process, the limiting ring 25 inside the boss 22 precisely aligns with the idle speed motor shaft, and the annular groove 26 on the bottom surface of the base 21 provides installation space for the coil frame, ensuring the compatibility between the housing and other internal components of the idle speed motor, laying the foundation for subsequent stable operation.

[0031] When the idle motor is running, the housing structure ensures the stable operation of the motor through the functions of each component. The conductive pin 3, as the core of the electrical connection, continuously and stably transmits signals and power between the motor and the outside with the help of the fixing effect of the socket housing 2, ensuring the transmission of idle speed control commands. Multiple docking structures work together to resist vibration. The nesting relationship between the inner groove 11 and the boss 22 prevents the housing from separating axially. The cooperation between the plug 24 and the slot 13, and the protrusion 23 and the notch 12 restricts horizontal sliding. The engagement between the protrusion 14 and the notch prevents relative rotation, keeping the housing as a whole stable and preventing the conductive pin 3 from making poor contact due to loosening.

[0032] Meanwhile, the receiving groove 251 of the limiting ring 25 provides guidance and positioning for the rotating shaft, ensuring coaxiality during shaft operation and reducing control anomalies caused by misalignment; the coil frame in the ring groove 26 optimizes the electromagnetic environment through regular coil arrangement, improving motor efficiency. In addition, the tightly fitted housing structure forms an effective seal, reducing the intrusion of oil and moisture, protecting internal components, extending overall service life, and ensuring long-term stable operation of the idle speed motor.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
