FIELD OF THE INVENTION
The present invention relates to electrical connection technology, and more particularly, to a connector housing and a connector.
BACKGROUND
A connector currently used in electrical connection (for example, in the electrical connection of an air compressor) cannot match with a mating structure quickly and accurately in place, due to lack of a pre-assembled positioning structure. This is not conducive to automating the electrical connection installation process. Therefore, there is a critical need for a connector which is more easily operated and can facilitate quick and accurate assembly.
SUMMARY
A connector housing includes a body having a first accommodating cavity accommodating a first terminal. A first insertion hole penetrates a first surface of the body and communicates with the first accommodating cavity. A guiding portion of the body surrounds at least a portion of the first insertion hole.

In the embodiment shown in FIGS. 1-6, a connector 100 comprises a first terminal 400a (shown in FIG. 6), a second terminal, and a connector housing 200. The connector housing 200 comprises a body 202 which includes a first accommodating cavity 204, a second accommodating cavity 208, a first insertion hole 210, and a second insertion hole 212. The first accommodating cavity 204 is configured to accommodate the first terminal 400a, and the second accommodating cavity 208 is configured to accommodate the second terminal. The first insertion hole 210 penetrates a first surface 202a of the body 202 and communicates with the first accommodating cavity 204, and the second insertion hole 212 penetrates the first surface 202a of the body 202 and communicates with the second accommodating cavity 208.
A guiding portion 220 comprises a first sub-guiding portion 214 and a second sub-guiding portion 216, as shown in FIG. 2. The first sub-guiding portion 214 surrounds a portion of the first insertion hole 210 and is configured to guide a first conductor 300a (for example, a metal pillar) of a conductive connection 300 into the first insertion hole 210, and the second sub-guiding portion 216 surrounds a portion of the second insertion hole 212 and is configured to guide a second conductor 300b (for example, a metal pillar) of the conductive connection 300 into the second insertion hole 212. It should be understood that, in another embodiment, the first sub-guiding portion 214 completely surrounds the first insertion hole 210, and the second sub-guiding portion 216 completely surrounds the second insertion hole 212. In another embodiment, the first sub-guiding portion 214 is integrally connected to the second sub-guiding portion 216, though in the embodiment shown in FIGS. 1-3, the first sub-guiding portion 214 is completely spaced apart from the second sub-guiding portion 216.
As shown in FIGS. 2 and 3, the first sub-guiding portion 214 and the second sub-guiding portion 216 respectively comprise a first protrusion 214a and a second protrusion 216a which extend outwardly from the first surface 202a. The first protrusion 214a has a first guiding surface 214b relative to the first surface 202a, which makes it easier to guide the first conductor 300a into the first insertion hole 210, and the second protrusion 216a has a second guiding surface 216b that is tilted relative to the first surface 202a, which makes it easier to guide the second conductor 300b into the second insertion hole 212. It should be understood that, in another embodiment, the first protrusion 214a without the tilted first guiding surface 214b, and the second protrusion 216a without the tilted second guiding surface 216b, may also facilitate guiding functions.
The connector housing 200 further comprises a third accommodating cavity and a third insertion hole 218 (shown in FIG. 2); the third accommodating cavity is configured to accommodate a third terminal. The third insertion hole 218 penetrates the first surface 202a of the connector housing 202 and communicates with the third accommodating cavity, wherein when the conductive connection 300 is mounted on the connector housing 202, the first terminal 300a of the conductive connection 300 enters into the first insertion hole 210 via the guidance of the first sub-guiding portion 214 and forms an electrical connection with the first terminal 400a in the first accommodating cavity 204. The second conductor 300b of the conductive connection 300 enters into the second insertion hole 212 via the guidance of the second sub-guiding portion 216 and forms an electrical connection with the second terminal in the second accommodating cavity 208. A third conductor 300c of the conductive connection 300 enters into the third insertion hole 218 and forms an electrical connection with the third terminal.
When the connector 200 is completely assembled, one end of wire 500a, one end of wire 500b, and one end of wire 500c form electrical connections with one end of the first conductor 300a, one end of the second conductor 300b, and one end of the third conductor 300c of the conductive connection 300, via the first terminal 400a, the second terminal, and the third terminal respectively. The other end of the first conductor 300a, the other end of the second conductor 300b, and the other one end of the third conductor 300c are connected to the air compressor, and the other end of wire 500a, the other one end of wire 500b, and the other one end of wire 500c are connected to power supply, providing power supply for the air compressor.
In the second embodiment shown in FIGS. 7-11, a connector 700 comprises a first terminal 400a (as shown in FIG. 6), a second terminal, a third terminal, and a connector housing 600. The connector housing 600 comprises a body 602 which includes a first accommodating cavity 604, a second accommodating cavity 608, a third accommodating cavity 622, a first insertion hole 610, a second insertion hole 612, and a third insertion hole 618. The first accommodating cavity 604 is configured to accommodate the first terminal 400a, and the second accommodating cavity 608 is configured to accommodate the second terminal. The third accommodating cavity 622 is configured to accommodate the third terminal. The first insertion hole 610 penetrates a first surface 602a of the body 602 and communicates with the first accommodating cavity 604, the second insertion hole 612 penetrates the first surface 602a of the body 602 and communicates with the second accommodating cavity 608, and the third insertion hole 618 penetrates the first surface 602a of the body 602 and communicates with the third accommodating cavity 622.
For the second embodiment shown in FIGS. 7-11 and the first embodiment shown in FIGS. 1-6, the majority of structures are similar, and the distinction is that the structure of a guiding portion 620 is different from that of the guiding portion 220.
The guiding portion 620 comprises a first sub-guiding portion 614 and a second sub-guiding portion 616. The first sub-guiding portion 614 surrounds a portion of the first insertion hole 610 and is configured to guide the first conductor 300a (for example, a metal pillar) of the conductive connection 300 into the first insertion hole 610. The second sub-guiding portion 616 surrounds a portion of the second insertion hole 612 and is configured to guide the second conductor 300b (for example, a metal pillar) of the conductive connection 300 into the second insertion hole 612. In an embodiment, the first sub-guiding portion 614 and the second sub-guiding portion 616 respectively comprise a first recess 614a and a second recess 616a that are formed by being recessed from the first surface 602a towards the interior of the connector housing 602. The first recess 614 has a first sidewall 614b that is perpendicular to the first surface 602a, and the second recess 616 has a second sidewall 616b that is perpendicular to the first surface 602a. In another embodiment, the first recess 614 has the first sidewall 614b that is tilted relative to the first surface 602a, which makes it easier to guide the first conductor 300a into the first insertion hole 610, and the second recess 616 has the second sidewall 616b that is tilted relative to the first surface 602a, which makes it easier to guide the second conductor 300b into the second insertion hole 612.
As shown in FIGS. 7-11, when the conductive connection 300 is mounted on the connector housing 602, the first conductor 300a of the conductive connection 300 enters into the first insertion hole 610 via the guidance of the first sub-guiding portion 614 and forms an electrical connection with the first terminal 400a of the first accommodating cavity 604, the second conductor 300b of the conductive connection 300 enters into the second insertion hole 612 via the guidance of the second sub-guiding portion 616 and forms an electrical connection with the second terminal of the second accommodating cavity 608, and the third conductor 300c of the conductive connection 300 enters into the third insertion hole 618 and forms an electrical connection with the third terminal. When the connector 700 is completely assembled, one end of wire 500a, one end of wire 500b, and one end of wire 500c form electrical connections with one end of the first conductor 300a, one end of the second conductor 300b, and one end of the third conductor 300c of the conductive connection 300, via the first terminal 400a, the second terminal, and the third terminal respectively. The other end of the first conductor 300a, the other end of the second conductor 300b, and the other one end of the third conductor 300c are connected to the air compressor, and the other end of wire 500a, the other one end of wire 500b, and the other one end of wire 500c are connected to power supply, providing power supply for the air compressor.
