Description

Technical Field

[0001] This utility model relates to a connector structure, and more particularly to a split connector structure in an applied motor oil pump controller assembly. Background Technology

[0002] Connectors, also known as electrical connectors, are devices that connect two active components to transmit current or signals. Connectors are widely used in various modern devices. Traditionally, male connectors for electro-hydraulic pumps are injection molded directly from the pins to the connector housing, and are fixed to the PCB by soldering. This traditional structure adds a soldering step to the production line, increasing costs. Furthermore, due to assembly sequence and structural issues, some products cannot be soldered after the connector is inserted into the PCB. Additionally, because different vehicle manufacturers specify different connector models, it is difficult to achieve platform-based design with a one-piece injection molded pin and housing structure. Summary of the Invention

[0003] This utility model provides a split connector structure that can adapt to multiple models, reduce costs, and realize platform-based development; it solves the technical problem in the prior art that the connectors of motor oil pump controllers need to be designed in multiple sets according to different customer needs, making it difficult to achieve platform-based design.

[0004] The above-mentioned technical problem of this utility model is solved by the following technical solution: a split connector structure, including a connector housing connected to a controller cover, a through-cavity provided in the center of the connector housing, and a pin assembly installed in the cavity. The pin assembly includes a pin body and a PIN pin. The pin body is fixed to the PCBA board by a positioning post, and the PIN pin is electrically connected to the PCBA board. This connector structure not only eliminates the soldering process on the production line but also reduces costs and shortens the product manufacturing cycle. Furthermore, this split connector allows the pin assembly to be designed as a platform component. If different customers specify different connector models, we only need to redesign and manufacture the connector housing. This platform design greatly reduces costs, shortens the R&D cycle, and enables platform-based product development. The pin body also does not require soldering; it is directly fixed by an interference fit of the positioning post, resulting in a simple structure and process.

[0005] Preferably, the lower part of the pin body has two integrally formed stepped pillars. The smaller diameter section of the stepped pillars serves as a positioning pillar, with positioning holes on the PCBA board. The positioning pillars and positioning holes are interference-fitted. The larger diameter section of the stepped pillars can support and form a gap between the pin body and the PCBA board, while the lower section of the stepped pillars directly interferes with the positioning holes on the PCBA board, thus fixing the pin body.

[0006] Preferably, the outer circumferential surface of the positioning post is formed with multiple axially arranged ribs. By setting the ribs, the fixing effect between the pin body and the PCBA board is improved.

[0007] Preferably, the receiving cavity of the connector housing is clearance-fitted with the pin assembly, facilitating assembly and disassembly.

[0008] Preferably, the PCBA board is equipped with pin spring clips, and the pins are inserted into the pin spring clips. This allows the pins to be easily inserted into the spring clips, thereby achieving electrical connection.

[0009] Preferably, the connector housing includes a base and a connector body. The base has a through hole near its outer side, and the controller cover has a corresponding pin hole. The connector housing and the controller cover are connected by a pin. This eliminates the need for bolts, reducing cost and weight.

[0010] Preferably, a positioning rib is provided below the base of the connector housing, and a positioning groove corresponding to the positioning rib is provided on the controller cover. An anti-misalignment protrusion is provided on the side of the base of the connector housing, and an anti-misalignment groove corresponding to the anti-misalignment protrusion is provided on the controller cover. This facilitates the positioning and connection of the connector with the controller cover.

[0011] Preferably, the two diagonal corners of the lower part of the pin body are provided with recessed notches. The pin body is integrally molded from plastic to prevent dimensional deviations or deformation during injection molding. The recessed notch at the assembly end of the pin body facilitates the fitting of the pin assembly and the connector housing.

[0012] Therefore, the split connector structure of this utility model has the following advantages:

[0013] 1) The connector has a split structure. This design allows the connector to be designed as a platform product. If the customer specifies different connector models, we only need to change the connector shell.

[0014] 2) The connector pin assembly is inserted into the PCBA. The connection between the pin and the PCBA is achieved directly through the contact between the pin and the spring. The connector pin assembly is fixed by the interference fit of the positioning post. This design eliminates the soldering process, reduces the cost of soldering equipment, and shortens the product manufacturing cycle. Attached Figure Description

[0022] The technical solution of the utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0023] Example:

[0024] like Figure 1 and 2 As shown in Figure 3, a split connector structure includes a connector housing 1 connected to a controller cover 4. The connector housing 1 has a through-hole receiving cavity 22, and a pin assembly 2 is installed in the receiving cavity 22. The pin assembly 2 includes an integrally injection-molded pin body 8 and a PIN pin 7. The controller cover 4 is welded to the motor body 3, and a PCBA board 9, a stator assembly, and a rotor assembly are installed in the cavity formed by the controller cover 4 and the motor body 3.

[0025] like Figure 4 and 5As shown, the pin body 8 is a cuboid. Two concave notches 10 are formed at the two corners of the diagonal below the pin body 8 to prevent plastic deformation and facilitate easier connection between the pin body 8 and the connector housing 1. The pin body 8 and the connector housing 1 have a clearance fit. Two stepped pillars 11 are integrally formed below the pin body 8. The diameter of the upper pillar is larger than that of the lower pillar. The smaller diameter section of the stepped pillar is a positioning pillar 12. Positioning holes are provided on the PCBA board. Multiple axially arranged ribs 13 are formed on the outer circumferential surface of the positioning pillar 12. The positioning pillar 13 and the positioning hole are interference-fitted.

[0026] On the PCBA board 9, pin spring clips 6, corresponding to the number of pins, are connected via SMT. The pin spring clips 6 include two clips, and the pins 7 can be directly inserted into the two clips to achieve electrical connection. This eliminates the soldering process, reduces the cost of soldering equipment, and shortens the product manufacturing cycle.

[0027] like Figure 6 and 7 As shown, the connector housing 1 includes a base 15 and a connector body 17. Each part of the base 17 near its outer side has a through hole 18. The controller cover 4 has a pin hole 19 corresponding to the through hole. The connector housing 1 and the controller cover 4 are connected by a pin 5. A positioning rib 16 is provided below the base of the connector housing 1, and a positioning groove 21 corresponding to the positioning rib 16 is provided on the controller cover 4. An anti-mistake protrusion 14 is provided on the side of the base of the connector housing 1, and an anti-mistake groove 20 corresponding to the anti-mistake protrusion is provided on the controller cover 4.

[0028] In use, the PCBA board must first be pre-soldered with pin spring clips designed according to the pin dimensions using SMT. Then, the pin assembly is assembled into the PCBA, and finally, the connector housing is assembled. The connector housing is secured by a corresponding fixing design on the controller cover. This new connector structure not only eliminates the soldering process on the production line but also reduces costs and shortens the product manufacturing cycle. Furthermore, this split-type connector allows the pin assembly to be designed as a platform component. This way, if different customers specify different connector models, we only need to redesign and manufacture the connector housing. This platform-based design significantly reduces costs, shortens the R&D cycle, and enables platform-based product development.
