[0033] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1-Figure 6 The connector 100 according to the embodiment of the present invention is described. The connector 100 includes: a first housing 10 , a second housing 20 , a connecting terminal 30 and a retaining member 40 .

[0034] Specifically, if Figure 1-Figure 5 As shown, the second shell 20 is arranged in the first shell 10, the connecting terminal 30 is arranged on the second shell 20, the retaining member 40 is arranged on the second shell 20, and the retaining member 40 cooperates with the connecting terminal 30 to limit the connecting terminal 30 to move in the direction of escaping from the second shell 20.

[0035] In this embodiment, the connecting terminal 30 is matched with the second housing 20 along the installation direction B of the second housing 20, and the second housing 20 equipped with the connecting terminal 30 is matched with the first housing 10. The assembly direction A of the retaining member 40 is perpendicular to the installation direction B of the second housing 20. After the retaining member 40 is pre-installed with the second housing 20, it is matched with the connecting terminal 30 in the second housing 20, which facilitates the installation of the connecting terminal 30, realizes the limiting of the connecting terminal 30, and prevents the connecting terminal 30 from falling out of the second housing 20 along the installation direction B of the second housing 20.

[0036] The second housing 20 is provided with a plurality of sealing holes 24 , and the connecting terminals 30 are matched with the sealing holes 24 , and the connecting terminals 30 and the sealing holes 24 are interference fit to form a waterproof seal of the connector 100 .

[0037] According to the connector 100 of the embodiment of the utility model, the retaining member 40 is arranged so that when the retaining member 40 is installed in the second shell 20, it is prevented from falling off from the second shell 20 and causing rework, so that the retaining member 40 cooperates with the connecting terminal 30 to achieve the limitation of the connecting terminal 30, which is convenient for the installation of the connecting terminal 30 while ensuring the reliability of the installation of the connecting terminal 30, and preventing the connecting terminal 30 from falling off from the second shell 20. The retaining member 40 has a simple structure, which can effectively reduce the cost of the product and improve the installation efficiency of the connector 100.

[0038] In some embodiments, Figure 3 and Figure 4As shown, at least one pre-installation position positioning groove 431 and at least one locking position positioning groove 432 are formed on the retaining member 40, and the pre-installation position positioning groove 431 and the locking position positioning groove 432 are arranged at intervals along the assembly direction A of the retaining member 40. The pre-installation position positioning groove 431 is located at one end of the locking position positioning groove 432 adjacent to the second housing 20 along the assembly direction A of the retaining member 40. When the retaining member 40 is installed in the second housing 20, the pre-installation position positioning groove 431 first contacts the second housing 20. For example, at least one matching protrusion 21 is provided on the second housing 20, and the matching protrusion 21 is suitable for matching in one of the pre-installation position positioning groove 431 and the locking position positioning groove 432.

[0039] That is, when the retaining member 40 is pre-installed with the second shell 20, in order to prevent the retaining member 40 from falling off, the pre-installation position positioning groove 431 on the retaining member 40 cooperates with the mating protrusion 21 to realize the pre-installation of the retaining member 40, and prevent the retaining member 40 from falling off when it is not assembled in place. The second shell 20 has a mating protrusion 21 opposite to it. When the retaining member 40 is assembled on the second shell 20, the mating protrusion 21 is made to cooperate with the pre-installation position positioning groove 431, which can effectively prevent the locking position positioning groove 432 of the retaining member 40 from cooperating with the mating protrusion 21 during pre-installation, and facilitate the installation of the connecting terminal 30. Then, the retaining member 40 is pressed to make the locking position positioning groove 432 cooperate with the mating protrusion 21, so as to realize the installation of the retaining member 40 and the fixation and limitation of the connecting terminal 30.

[0040] Therefore, the retaining member 40 is provided with a pre-installation position positioning groove 431 and a locking position positioning groove 432, and one of the pre-installation position positioning groove 431 and the locking position positioning groove 432 cooperates to keep the retaining member 40 connected to the second housing 20 at different stages, thereby preventing the retaining member 40 from falling off, and during the installation process of the retaining member 40, it is not necessary to insert the retaining member 40 multiple times, thereby improving the installation efficiency of the retaining member 40. It can also prevent the installer from touching it by mistake, and reduce the probability of rework of the connector 100.

[0041] In some embodiments, Figure 4 As shown, the retainer 40 includes: a body 41, an assembly portion 42, and at least one elastic arm 43. The body 41 is provided on the second housing 20, and the assembly portion 42 is provided at one end of the body 41 away from the second housing 20 along the assembly direction A; the elastic arm 43 is connected to the assembly portion 42, and the elastic arm 43 is located on one side of the width direction of the body 41, that is, the first direction C, and the pre-installation position positioning groove 431 and the locking position positioning groove 432 are formed on the elastic arm 43 at intervals from each other. The first direction C is orthogonal to the assembly direction A and the installation direction B.

[0042] An assembly portion 42 is provided at one end of the body 41 along the assembly direction A, and the assembly portion 42 and the body 41 are arranged in a T shape. The installer presses the assembly portion 42 to install the body 41 into the second housing 20. An elastic arm 43 is provided at at least one end of the assembly portion 42 along the width direction of the body 41, one end of the elastic arm 43 is connected to the assembly portion 42, and the other end of the elastic arm 43 extends toward the second housing 20 along the assembly direction of the retainer 40. The body 41 and the elastic arm 43 are arranged at intervals. The pre-installation position positioning groove 431 and the locking position positioning groove 432 are provided on the elastic arm 43, and can be specifically provided on the side of the elastic arm 43 adjacent to the body 41, so as to increase the utilization of the space on the retainer 40.

[0043] Optionally, the pre-installation position positioning groove 431 and the locking position positioning groove 432 can be provided at other positions of the elastic arm 43. The cross-sectional area of ​​the assembly portion 42 is larger than the cross-sectional area of ​​the body 41, which facilitates installation and force application by the installer and increases the reliability of the retainer 40 in the pre-installation position and the locking position.

[0044] Furthermore, combined with Figure 2 and Figure 4 There are two elastic arms 43, which are respectively located on both sides of the width direction of the body 41, and the pre-installation position positioning grooves 431 and the locking position positioning grooves 432 of the two elastic arms 43 are opposite to each other. There are two matching protrusions 21, which are suitable for matching in one of the pre-installation position positioning grooves 431 and the locking position positioning grooves 432 of the two elastic arms 43. That is, a matching protrusion 21 is respectively provided on both sides of the second shell 20 along the width direction of the body 41, and the two elastic arms 43 are symmetrically arranged along the width direction of the body 41. When the retainer 40 and the second shell 20 are matched at the pre-installation position positioning groove 431 or the locking position positioning groove 432, the retainer 40 is subjected to uniform force in the width direction of the body 41, which increases the service life of the retainer 40, so that the retainer 40 has good reliability and better stability when installed with the second shell 20.

[0045] In some embodiments, the elastic arm 43 and the body 41 are staggered in the thickness direction of the body 41. It can be understood that the elastic arm 43 is arranged on one side of the thickness direction of the body 41, that is, on one side of the body 41 along the installation direction B, such as the side of the elastic arm 43 along the thickness direction of the body 41 is flush with the side of the assembly portion 42 along the thickness direction of the body 41, so as to facilitate the installation of the retainer 40 and reduce the interference of the installation position of the elastic arm 43 on the installation of the body 41.

[0046] In some embodiments, as shown in the figure, the body 41 is located on one side of the installation direction B of the second housing 20, and the installation direction B is perpendicular to the assembly direction A. The connector 100 further includes: at least one limiting structure, the limiting structure is provided on the second housing 20, and the limiting structure cooperates with the elastic arm 43 to limit the movement of the retaining member 40 in the installation direction B in the direction away from the second housing 20. The limiting structure is formed on one side of the retaining member 40 adjacent to the retaining member 40 in the assembly direction A of the retaining member 40, and the limiting mechanism can limit the movement of the retaining member 40 in the installation direction B of the second housing 20, thereby limiting the position of the retaining member 40.

[0047] In this embodiment, there are multiple limiting structures, including a first limiting structure and a second limiting structure, and the first limiting structure and the second limiting structure are arranged at intervals along the first direction C. In addition, the limiting structure can be arranged on the other side of the second housing 20 along the installation direction B of the retaining member 40 according to needs, that is, both sides of the second housing 20 along the assembly direction A of the retaining member 40 can be provided with limiting structures for the installation of the retaining member 40.

[0048] In some embodiments, Figure 2 As shown, the limiting structure is a limiting groove 22 formed on the second housing 20, and the groove wall of the limiting groove 22 adjacent to the installation direction B of the second housing 20 is suitable for abutting against the elastic arm 43. That is, after the retaining member 40 is installed in the second housing 20, the elastic arm 43 abuts against the side wall of the second housing 20, and the second housing 20 limits the elastic arm 43, thereby increasing the stability and reliability of the retaining member 40 installed in the second housing 20 and avoiding abnormal noise generated by the retaining member 40 when installed in the second housing 20.

[0049] In some embodiments, at least a portion of the mating protrusion 21 is located in the limiting groove 22. For example, the mating protrusion 21 can be disposed at the notch of the limiting groove 22, which, on the one hand, facilitates the limiting of the pre-installed position positioning groove 431 and the locking position positioning groove 432 of the retainer 40 with the mating protrusion 21, and facilitates the installer to confirm whether the installation is correct. On the other hand, it can facilitate the limiting of the elastic arm 43 in the first direction C in combination with the side wall of the second housing 20, and increase the stability of the retainer 40 installed in the second housing 20.

[0050] In some embodiments, reference Figure 2A groove 23 is formed on the surface of one side of the second housing 20 in the installation direction B, and the body 41 is guided and matched with the groove 23. The groove 23 is provided on one side of the second housing 20 for installing the connecting terminal 30. After the retainer 40 is pre-installed with the second housing 20, that is, after the pre-installation position positioning groove 431 is matched with the matching protrusion 21, the second housing 20 is matched with the first housing 10 to realize the installation of the second housing 20 and the first housing 10, and then the connecting terminal 30 is installed into the second housing 20 from the side of the second housing 20 in the installation direction B away from the first housing 10. After the connecting terminal 30 is installed, the assembly part 42 is pressed to make the matching protrusion 21 of the second housing 20 match with the locking position positioning groove 432, so as to realize the locking and installation of the connecting terminal 30 by the retainer 40. Among them, after the retainer 40 is assembled with the second housing 20, the body 41 of the retainer 40 is matched with the groove 23, and the elastic arm 43 of the retainer 40 is matched in the limiting structure to realize the connection and fixation with the second housing 20.

[0051] According to the second aspect of the present invention, the connector assembly includes a first connector and a second connector. The first connector is configured as the connector in the above embodiment, and the second connector cooperates with the first connector.

[0052] In this embodiment, if Figure 6 As shown, the second connector also includes a third housing 50, which can be used as the female end of the connector assembly to be connected to one of the two wiring harnesses that need to be connected after the first housing 10 and the second housing 20 included in the first connector are installed. The third housing 50 is detachably connected to the first housing 10 on the side of the second housing 20 away from the connecting terminal 30, such as a matching groove is provided at the end of the third housing 50, and a matching portion is provided on the first housing 10, and the matching portion and the matching groove cooperate to achieve the installation of the first housing 10 and the third housing 50. The third housing 50 can be used as the male end of the connector assembly to be connected to the other of the two wiring harnesses that need to be connected, so that the electrical connection between the two wiring harnesses is achieved under the plugging of the male end of the connector assembly and the female end of the connector assembly. Therefore, the first connector and the second connector of the connecting assembly can be set to achieve accurate connection between the two wiring harnesses that need to be plugged in, thereby improving the efficiency and yield of the wiring harness connection.
