[0035] Example 1

[0036] A connector assembly, such as Figure 5 As shown, it includes a male connector 10 and a female connector 20 for plugging and mating, and a locking member 30 for locking the male connector 10 and the female connector 20. A first locking portion 101 is provided on the outer wall of one of the male connector 10 and the female connector 20 along a direction perpendicular to the plugging direction 50 of the male connector and the female connector, and a second locking portion 201 is provided on the outer wall of the other along a direction perpendicular to the plugging direction 50 of the male connector and the female connector. The first locking portion 101 and the second locking portion 201 are arranged opposite to each other, and the two are locked when the male connector 10 and the female connector 20 are plugged in. After being mated, a locking platform 40 is formed together, and the width of the locking platform 40 gradually increases in the direction away from the male connector 10 and the female connector 20. The interior of the locking member 30 is penetrated by a locking groove 301 that matches the shape of the locking platform 40 along a direction perpendicular to the plug-in direction 50 of the male connector and the female connector. In the present embodiment, the locking platform 40 is specifically an inverted step-shaped structure, and the locking groove 301 is a dovetail groove that matches the inverted step-shaped structure. The locking member 30 is clamped to the outer side of the locking platform 40 through the locking groove 301 to achieve locking of the male connector 10 and the female connector 20. The locking structure of the connector assembly of the present invention has strong stability, and can provide the connector assembly with safe and reliable anti-vibration capability, thereby enabling the connector assembly to meet the automotive-grade vibration requirements. Moreover, when the locking structure of the connector assembly of the present invention is unlocked, the male connector 10 and the female connector 20 can be unlocked by pushing the locking member 30, and then the male connector 10 and the female connector 20 can be separated. There is no need to pull out the male / female end of the backplane connector while pressing the locking structure. The operability is strong and the user experience is good.

[0037] Example 2

[0038] This embodiment is a preferred embodiment of the present utility model, and its difference from embodiment 1 is that, further, Figure 1 and Figure 2As shown, one of the first locking portion 101 and the second locking portion 201 is provided with an embedding groove 102 for accommodating the other. After the male connector 10 and the female connector 20 are plugged in, the first locking portion 101 and the second locking portion 201 are embedded and matched to form a locking platform 40. The provision of the embedding groove 102, on the one hand, plays a role in positioning and preventing mis-plugging for the plugging of the male connector 10 and the female connector 20. On the other hand, after the male connector 10 and the female connector 20 are plugged in, the embedding groove 102 and the second locking portion 201 cooperate to prevent the male connector 10 and the female connector 20 from shaking, thereby further improving the vibration resistance of the connector assembly.

[0039] In this embodiment, the first locking portion 101 is provided on the male connector 10 and the second locking portion 201 is provided on the female connector 20 as an example to describe the technical solution of the utility model in detail:

[0040] like Figure 2-Figure 4 As shown, the first locking portion 101 is arranged on the male end connector 10, and an embedding groove 102 for accommodating the second locking portion 201 is provided on the first locking portion 101. A pre-installed rear stop portion 103, a locked rear stop portion 104 and a locked front stop portion 105 are sequentially arranged on the side of the first locking portion 101 away from the second locking portion 201 along the direction 60 of the locking member being installed into the locking platform. A pre-installed area 106 for clamping the locking member 30 is formed between the pre-installed rear stop portion 103 and the locked rear stop portion 104, and a locking area 107 for clamping the locking member 30 is formed between the locked rear stop portion 104 and the locked front stop portion 105. Further, the cross-sectional shape of the first locking portion 101 at the pre-installed area 106 is the same as the cross-sectional shape of the locking platform 40, so that the locking member 30 can be easily installed.

[0041] The installation process of the locking member 30 of the utility model is as follows: first, the locking member 30 is installed on the male connector 10. At this time, the locking member 30 is clamped in the pre-installed area 106 between the pre-installed rear stop portion 103 and the locking rear stop portion 104; then the male connector 10 and the female connector 20 are plugged together. For details, please refer to Figure 3 Finally, the locking member 30 is pushed so that the locking member 30 crosses the locking rear stop portion 104 and switches from the pre-installed area 106 to the locking area 107 between the locking rear stop portion 104 and the locking front stop portion 105. For details, please refer to Figure 4At this time, the locking piece 30 is clamped on the outer side of the first locking portion 101 and the second locking portion 201 to lock the male connector 10 and the female connector 20; when unlocking the locking piece 30, the male connector 10 and the female connector 20 can be unlocked by pushing the locking piece 30 in the reverse direction, and then the male connector 10 and the female connector 20 can be separated. There is no need to pull out the male / female end of the backplane connector while pressing the locking structure, which has strong operability and good user experience.

[0042] Furthermore, if Figure 2 As shown, the embedding groove 102 is a rectangular groove, and the locking rear stop portion 104 and the locking front stop portion 105 are respectively located at the opposite ends of the embedding groove 102. At the same time, in order to ensure the stability of the male connector 10 and the female connector 20 after the locking member 30 is installed, the ratio of the length of the embedding groove 102 to the first locking portion 101 should not be less than 1 / 3, but considering the overall strength of the first locking portion 101, the ratio of the length of the embedding groove 102 to the first locking portion 101 should not be greater than 2 / 3.

[0043] In one embodiment, if Figure 1 and Figure 2 As shown, the pre-installed rear stop portion 103 and the locked rear stop portion 104 are both convex structures, and the locked front stop portion 105 is a long strip structure perpendicular to the first locking portion 101, so that the locking platform 40 is T-shaped as a whole. The design of the T-shaped structure can improve the strength of the locking platform 40, thereby preventing damage to the locking platform 40 due to excessive force when pushing the locking member 30.

[0044] In one embodiment, if Figure 1 As shown, the locking member 30 is attached to the outer wall of the male connector 10 on one side in the direction of being inserted into the locking platform 40, and is attached to the outer wall of the female connector 20 on the other side. Therefore, when the locking member 30 is pushed, the locking member 30 has good stability and will not be offset, thereby ensuring that the locking member 30 can slide to a predetermined position.

[0045] Example 3

[0046] The difference between this embodiment and embodiment 1 is that: Figure 6 As shown, the locking platform 40 is set as a T-shaped platform structure, the locking groove 301 is a T-shaped groove that matches the T-shaped platform structure, and the locking member 30 is connected to the outer side of the locking platform 40 through the locking groove 301 to achieve locking of the male connector 10 and the female connector 20.

[0047] Although some specific embodiments of the present invention have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
