[0026] The following description of the embodiments is with reference to the accompanying illustrations, which illustrate specific embodiments in which the present invention can be implemented.

[0027] This utility model provides a connector for aging testing of a vehicle controller, the structure of which is as follows: Figure 1 and Figure 2 As shown, it includes a housing 1 and two connectors 2, wherein the two connectors 2 are fixedly mounted on the housing 1, and the positions of the two connectors 2 on the housing 1 correspond one-to-one with the two communication ports of the vehicle controller; the two connectors 2 are respectively connected to an external test electromechanical device through a wiring harness.

[0028] The two connectors 2 are connected by the housing 1 to form a whole, which increases the overall volume and size of the connector. This makes it easier to find the point of force application when inserting / removing the connector, so that the force can be directly applied to the whole formed by the two connectors 2 and the housing 1, thereby avoiding damage to the wire harness when applying force. At the same time, the two connectors 2 are connected by the housing 1 to form a whole, so only one operation is needed when inserting / removing the connector. Compared with the prior art where two DB37 connectors are set independently, which requires operation on each DB37 connector separately, this reduces the number of insertion / removal operations and improves work efficiency.

[0029] Please continue to refer to Figure 1Specifically, in order to achieve a reasonable arrangement of the two connectors 2 on the housing 1, the housing 1 has a cavity with an opening (not shown in the figure), the two connectors 2 are arranged side by side and detachably fixed in the cavity, and the plug-in end of the connector 2 is arranged facing the opening of the cavity.

[0030] Furthermore, in order to enable the connector 2 to be connected to an external testing machine via a wire harness, a through hole (not shown in the figure) is provided on the side wall of the cavity for inserting the wire harness and electrically connecting it to the corresponding connector 2.

[0031] Preferably, in order to minimize the pulling of the wire harness when inserting / removing the connector, the through hole is formed on the side wall of the cavity along the insertion / removal direction perpendicular to the connector 2.

[0032] Furthermore, to prevent moisture from entering the cavity through the through hole, the connector for aging testing of the vehicle controller also includes a sealing component 4. The sealing component 4 includes a threaded sleeve 41, a sealing plug 42, and a nut 43. The threaded sleeve 41 is fixedly installed on the outer wall of the housing 1 at the through hole, and the outer surface of the threaded sleeve 41 has an external thread. The sealing plug 42 is movably fitted inside the nut 43, and the inner diameter of the sealing plug 42 matches the outer diameter of the wire harness. Preferably, the sealing plug 42 is a T-shaped sealing plug. The nut 43 is threadedly connected to the threaded sleeve 41.

[0033] It is understood that after the wire harness passes through the sealing plug 42 and the screw sleeve 41, the nut 43 is tightened. The sealing plug 42 can seal the circumference of the wire harness, thereby preventing moisture from entering the cavity.

[0034] like Figure 2 The image shown is a bottom view of the connector for aging test of the vehicle controller. In this embodiment, the connector for aging test of the vehicle controller further includes a locking assembly 3, which includes a handle 31 that passes through the housing 1 and extends to the outside of the housing 1.

[0035] After the locking assembly 3 is locked, at least one of the connectors 2 and the corresponding communication port are locked in a connected state; after the locking assembly 3 is unlocked, the connection between the connector 2 and the corresponding communication port can be released.

[0036] It should be noted that since using a locking assembly to lock two interconnected parts to improve the strength of the connection is an existing technology (such as in common connectors, where the male and female connectors are connected by a locking mechanism), the structure and specific locking principle of the locking assembly 3 will not be described in detail in this embodiment.

[0037] Further, the shell 1 is provided with a groove 11 matching the shape of the handle 31; after the lock assembly 3 is unlocked, the handle 31 is received in the groove 11.

[0038] It is easy to understand that the groove 11 can receive the handle 31 of the lock assembly 3 in the unlocked state, so as to avoid the handle 31 protruding from the outside of the shell 1 and hindering the force applied to the shell 1 when the connector is inserted or pulled out.

[0039] For the convenience of understanding the scheme, the working principle of the embodiment of the utility model will be described in detail as follows. Figure 1 and Figure 2 For the convenience of understanding the scheme, the working principle of the embodiment of the utility model will be described in detail as follows.

[0040] In work, the whole formed by the two connection heads 2 and the shell 1 is held by hand, and after the two connection heads 2 are aligned with the two communication ports of the controller to be tested, the two connection heads 2 are simultaneously inserted into the two communication ports of the controller, and the wire harnesses of the two connection heads 2 are connected with the external tester, and the tester is turned on, so that the controller can be tested.

[0041] After the test is completed, the tester is turned off, and the two connection heads 2 are pulled out by holding the shell 1.

[0042] In summary, in the connector for vehicle controller aging test, the shell 1 is additionally provided, and the two connection heads 2 are connected to form a whole through the shell 1, so that the whole formed by the two connection heads 2 and the shell 1 can be inserted or pulled out when the controller is tested, and compared with the two DB37 connection heads independently provided in the prior art, the two connection heads 2 only need to be inserted or pulled out once; in addition, the groove 11 on the shell 1 can receive the handle 31 of the lock assembly 3 in the unlocked state, so as to avoid the handle 31 protruding from the outside of the shell 1 and hindering the force applied to the shell 1 when the connector is inserted or pulled out.

[0043] It should be noted that although the utility model is disclosed as above with specific embodiments, the above embodiments are not used to limit the utility model, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the utility model, therefore the protection scope of the utility model is defined by the scope of claims.
