Detailed Description

The technical scheme of the invention is further specifically described below through examples and with reference to the accompanying drawings. In the specification, the same or similar reference numerals denote the same or similar components. The following description of embodiments of the present invention with reference to the accompanying drawings is intended to illustrate the general inventive concept and should not be taken as limiting the invention.

The terms "comprising," including, "and similar terms used herein should be interpreted as open-ended terms, i.e., including, but not limited to," meaning that other elements may also be included. The term "based on" is based at least in part on. The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment," and so forth.

The invention mainly focuses on the following technical problems: how to optimize the connector without changing the parameters and dimensions of the receptacle terminals to improve the transmission stability of the connector.

In order to solve the problems, the invention discloses a connector and a connector housing. The connector housing comprises at least one accommodating cavity and a socket arranged on the bottom wall of the accommodating cavity, wherein a blocking piece is arranged in the accommodating cavity, and the accommodating cavity is used for inserting and mounting the socket terminal in the first direction; the socket is used for receiving the spliced pin terminal from the second direction; after the pin terminal is inserted into the socket, the pin terminal is in matched contact with a pair of side walls of the socket terminal; the blocking member is configured to limit movement of the receptacle terminal in a second direction after the receptacle terminal is disposed in the receiving cavity, wherein the second direction is perpendicular to the first direction.

Example one

As shown in fig. 2 a-2 c, one example of the disclosed connector is described, which includes a connector housing 10 and receptacle terminals 20 disposed within the connector housing 10. In this example, after the receptacle terminal 20 is inserted into the connector housing 10 in the first direction X (e.g., direction X shown in fig. 3 b), the pin terminal 200 is plugged into the connector housing 10 and contacts a pair of sidewalls of the receptacle terminal 20.

Specifically, fig. 2b is a cross-sectional view as the present example showing a specific structure of the connector disclosed in the example. Fig. 2c shows further details of the connector disclosed in this example as a partial enlarged view of part B in fig. 2B.

As shown in fig. 2b, 2c, the connector housing 10 comprises at least one receiving cavity 11, a socket 17 provided on a bottom wall 12 of the receiving cavity 11, and a blocking member 13 provided on an end wall (not shown) of the receiving cavity 11. Specifically, the stopper 13 is formed extending from the end wall of the accommodation chamber 11 in a direction opposite to the first direction X.

In addition, as shown in fig. 2b, a first gap 14 is formed between the stopper 13 and the bottom wall 12 of the housing chamber 11, and after the receptacle terminal 20 is inserted into the connector housing 10, a part of the bottom wall 21 of the receptacle terminal 20 is disposed in the first gap 14.

Meanwhile, a second gap (not shown) exists between the blocking member 13 and the socket 17 in the direction opposite to the first direction X, so that the pin terminal 20 and the blocking member 13 are spaced apart from each other after the pin terminal 200 is inserted into the socket 17, so as to ensure that the blocking member 13 does not affect the normal operation of the pin terminal 200 and the socket terminal 20.

In practical applications, the range of the first gap 14 is 1-1.5 times the thickness of the bottom wall 21 of the receptacle terminal 20, so that after the receptacle terminal 20 is inserted into the connector housing 10, a distance between a portion of the bottom wall 21 and the stopper 13 is 0-0.5 times the thickness of the bottom wall 21, thereby effectively reducing and restricting the movement of the receptacle terminal 20 in the second direction Y (e.g., the direction Y in fig. 2 c).

In actual use of the connector disclosed in this example, after the pin terminals 200 are inserted into the connector housing 10 and the receptacle terminals 20 in the second direction Y, the pin terminals 200 are in electrical contact with a pair of side walls of the receptacle terminals 20 to perform the relevant functions of the connector. Meanwhile, in use, since the stopper 13 is provided, the bottom wall 21 of the receptacle terminal 20 is restricted from being movable only between the bottom wall 12 of the connector housing 10 and the stopper 13, and as described above, the range of movement of the receptacle terminal 20 in the second direction Y is 0 to 0.5 times the thickness of the bottom wall 21. This distance of movement does not create additional impedance nor affect the electrical contact area of the pin terminals 200 and the socket terminals 20, thereby improving the stability of the connector in use.

Example two

As shown in fig. 3 a-3 c, another example of the disclosed connector is described. In this example, after the receptacle terminal 20 is inserted into the connector housing 10 in the first direction X, the pin terminal 200 is inserted into the connector housing 10 and contacts a pair of sidewalls of the receptacle terminal 20.

Specifically, fig. 3a shows an overall state in which the receptacle terminal 20 is inserted into the connector housing 10, and fig. 3b shows a state in which a part of the receptacle terminal 20 is inserted into the connector housing 10 as one of sectional views of the present example. Fig. 3c is a second cross-sectional view of the present example showing a state in which the receptacle terminal 20 is fully inserted into the connector housing 10.

As shown in fig. 3 a-3 c, the connector housing 10 comprises one or more receiving cavities 11, a socket 17 provided on a bottom wall 12 of the receiving cavity 11, and a blocking member 13 provided within the receiving cavity 11. Specifically, the blocking member 13 is disposed in the accommodation chamber 11 in parallel with the bottom wall 12 of the accommodation chamber 11.

In addition, as shown in fig. 3b, a first gap 14 is formed between the stopper 13 and the bottom wall 12 of the housing chamber 11, and after the receptacle terminal 20 is inserted into the connector housing 10, a pair of side walls 22 and a bottom wall (not shown) of the receptacle terminal 20 are disposed in the first gap 14.

Meanwhile, as shown in fig. 3c, a portion of the bottom of the stopper 13 formed in this example forms an angle α with the bottom wall 12 of the accommodating chamber 11 in a direction opposite to the first direction X.

In this example, the angle α can facilitate insertion of the receptacle terminal 20 into the connector housing 10, that is, the angle α facilitates smooth insertion of the receptacle terminal 20 into the connector housing 10.

In practical use, after the receptacle terminal 20 is inserted into the connector housing 10, the third gap 16 is formed in the second direction Y between the bottom of the stopper 13 and the upper ends 221 of the pair of side walls 22 of the receptacle terminal 20. Specifically, the minimum dimension of the third gap 16 ranges from 0 to 0.5 times the thickness of the bottom wall of the receptacle terminal 20.

In addition, as shown in fig. 3a to 3c, a guide member 15 is further provided in the receiving chamber 11, and the guide member 15 is perpendicular to the blocking member 13, provides a guide for inserting the socket terminals 20 into the connector housing 10, and prevents problems of tilting and inaccurate assembly during the insertion of the socket terminals 20 into the receiving chamber 11 of the connector housing 10.

The connector disclosed in this example utilizes the guide 15 to ensure that the receptacle terminal 20 is prevented from tilting, being positioned inaccurately during assembly of the receptacle terminal 20 to the corresponding receiving cavity 11 of the connector housing 10, while ensuring that the receptacle terminal 20 is smoothly assembled inside the connector housing 10 by means of the inclined plane of the bottom of the blocking member 13 (i.e., the angle α between a portion of the bottom of the blocking member 13 and the bottom wall 12).

Further, after the pin terminal 200 is inserted into the connector housing 10 and the socket terminal 20 in the second direction Y, the pin terminal 200 is in electrical contact with a pair of side walls of the socket terminal 20 to perform a related function. Meanwhile, in use, since the stopper 13 is provided, the side wall 22 of the receptacle terminal 20 is restricted from being movable only between the bottom wall 12 of the connector housing 10 and the stopper 13, and as described above, the range of movement of the receptacle terminal 20 in the second direction is 0 to 0.5 times the thickness of the bottom wall 21. This distance of movement does not create additional impedance nor affect the electrical contact area of the pin terminals 200 and the socket terminals 20, thereby improving the stability of the connector in use.

The foregoing is merely an alternative embodiment of the present disclosure, and is not intended to limit the embodiments of the present disclosure, and various modifications and variations may be made to the embodiments of the present disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the embodiments of the present disclosure are intended to be included within the scope of the embodiments of the present disclosure.
