Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

As shown in fig. 1-2 and fig. 4-5, the device for detecting the insertion of a wire harness terminal according to an embodiment of the present application includes a female end 1 in the wire harness terminal, and further includes a warning component and a contact member 2 fixed relative to the female end 1, where the contact member 2 is a conductor, and specifically may be an iron block or a copper block, and the number of the contact members 2 is at least two, and the warning component may play a role in warning, for example, may use an indicator lamp or a speaker, and has the following characteristics:

When the sub-end is separated from the bottom of the jack of the female end 1, it can be understood that although the sub-end is inserted in the female end 1, the sub-end is in contact with the two contacts 2 in positional relationship when the sub-end is not inserted tightly, a diagram for forming the positional relationship is shown in fig. 1-2, and according to the diagram, when the sub-terminal on the wire harness is loosened, i.e. the sub-terminal moves left, the tail of the terminal touches the two contacts 2, i.e. a contact relationship is formed;

A power supply circuit is connected between the contact piece 2 and the warning component and is used for supplying power to the warning component, the power supply circuit can be a loop, the warning component is connected in series between the two contact pieces 2, a power supply in the loop can be provided by a vehicle, when a sub-end contacts the two contact pieces 2, the two contact pieces 2 are directly conducted through the effect of a conductor, so that the whole power supply circuit can be conducted, and the warning component works;

Based on the above, as long as the sub-terminal is inserted in the jack of female end 1, and when the slackening appears, make the sub-terminal can contact two contact members 2 simultaneously through positional relationship, thereby make power supply circuit switch on, warning part carries out work, thereby inform personnel with the information that the pencil appears contacting the trouble, make personnel know which pencil appears the trouble in particular, thereby be favorable to personnel to troubleshoot rapidly, for better messenger's discovery trouble department, when warning part is concrete warning light or speaker, it can directly set up on corresponding female end 1, in addition, it can also be virtual warning part, be the warning light sign and show on the display screen in the car, when the sign appears on the screen, synchronous display corresponds female end 1 the sign can, thereby be favorable to personnel to find the trouble terminal fast.

As shown in fig. 2 and 5, in some embodiments, there is also this positional relationship with respect to the apparatus: when the son terminal moves towards the direction away from the bottom of the jack of the mother terminal 1, the contact piece 2 is abutted against the tail of the son terminal, so that the distance between the two contact pieces 2 can be slightly smaller than the diameter of the son terminal in order to achieve the relation, and accordingly, when the son terminal is pulled out, the contact piece 2 can form an abutting contact, so that the son terminal is not blocked when being inserted into the mother terminal 1, the position relation between the contact piece 2 and the mother terminal 1 can be configured after the son terminal is inserted, and when the son terminal is loosened on the mother terminal 1, the contact piece 2 blocks the son terminal, further movement of the son terminal on the mother terminal 1 can be prevented, further loosening is prevented, and the occurrence of component fault phenomenon is reduced.

As shown in fig. 2, in some embodiments, the contact 2 includes a connection portion 3 and a contact portion 4, where the connection portion 3 and the female end 1 are relatively fixedly disposed, the contact portion 4 and the connection portion 3 are elastically connected, specifically, the contact 2 may use a copper block or an iron block with a sheet structure, two ends of the sheet form the connection portion 3 and the contact portion 4 respectively, and the two ends are connected by an arc bend of the sheet structure, so as to achieve an elastic connection effect, the contact portion 4 is specifically used for contacting the sub-end, and is responsible for completing the interference of the sub-end, and by setting the elastic connection effect, the distance between the two contact portions 4 can be changed by elastic yielding, so that insertion of the sub-end on the female end 1 is facilitated, the sub-end is not blocked by the contact portion 4 when inserted, and is not blocked when the sub-end is pulled out, so that the wire harness is conveniently disconnected when the sub-end is overhauled.

As shown in fig. 1 and 2, in some embodiments, the contact portion 4 is configured with a first surface 5 and a second surface 6 that are connected to each other, and each of the first surface and the second surface is used for contacting a sub-terminal, and forms an inclination with a depth direction of a jack of the female terminal 1, so as to achieve an effect of an inclined plane, and when the sub-terminal is inserted into or pulled out from the female terminal 1, the contact portion 4 can automatically avoid the sub-terminal by virtue of the effect of the inclined plane, so that a distance between the two contact terminals does not need to be manually spread.

As shown in fig. 1, in some embodiments, the connection portion 3 is arranged in a transversely extending manner, and the number of the contact portions 4 is plural, and the contact portions are sequentially distributed along the extending direction of the connection portion 3, so that when a plurality of jacks are simultaneously arranged on one female end 1, two contact members 2 can still be shared in the whole through the connection between one plurality of wire harnesses and the female end 1, and the warning component can be saved into one.

In some embodiments, the connection portion 3 and the female end 1 may be specifically configured to be detachably and fixedly connected, so as to achieve the effect of relatively fixing the connection portion 3 and the female end 1, and simultaneously make the whole contact member 2 detachable alone.

As shown in fig. 2, in some embodiments, the connection strip 7 is configured on the connection portion 3, and the linear slot 8 for sliding insertion of the connection strip 7 is configured on the female end 1, so that the connection and disconnection process can be performed in a plugging manner, which makes the connection and disconnection simpler and more convenient, and does not require the cooperation of additional tools.

As shown in fig. 1 to 3, in some embodiments, the connection strip 7 is linearly extended and is consistent with the extending direction of the connection portion 3, so as to play a role in reinforcing the connection portion 3, and meanwhile, the sliding direction of the connection strip 7 on the linear slot 8 is perpendicular to the moving direction of the sub-end in the jack of the female end 1 through the design, so that the sub-end cannot cause the contact 2 to form movement on the female end 1 during the insertion or the extraction, thereby being beneficial to stable installation.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the application. Thus, the present application is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
