Description

Signal wire harness with fool-proof function

Technical Field

The utility model relates to a signal pencil technical field particularly, relates to a signal pencil with prevent slow-witted function.

Background

The signal harness generally comprises a male connector and a female connector, and a power lead, a signal lead and a shielding wire are generally arranged in the male connector and the female connector. The male connector and the female connector can be detachably connected, so that a power supply lead, a signal lead and a shielding wire of the male connector and the female connector are uniformly and correspondingly connected.

Obviously, when the male connector and the female connector are connected, the male connector and the female connector must be matched accurately to ensure that various wires between the male connector and the female connector can be connected in a one-to-one correspondence manner. In the prior art, the fool-proof structure is adopted to correspond to the color between the male connector and the female connector. However, fool-proofing in color reduces the efficiency of assembly and also does not guarantee good fool-proofing. Wherein the structure is prevented staying or the structure is too complicated to increase the cost, or can not play fine staying of preventing, when installing energetically, the wrong condition together can appear in male joint and female joint. In view of the above, the inventors of the present invention have made a study of the prior art and then have made the present application.

SUMMERY OF THE UTILITY MODEL

The utility model provides a signal pencil with prevent slow-witted function aims at improving prior art's signal pencil and can not play fine problem of running dull.

In order to solve the technical problem, the utility model provides a signal harness with prevent slow-witted function contains:

the male connector is provided with a D-shaped mounting groove, a plurality of plugs arranged in the mounting groove and fool-proof bulges arranged on the side wall of the mounting groove;

the female joint comprises a mounting head which is D-shaped and is matched with the mounting groove, a plurality of jacks which are arranged on the mounting head and are matched with the plurality of plugs, and a foolproof groove which is arranged on the mounting head and is matched with the foolproof bulge;

the mounting groove is configured on the mounting head, the fool-proof protrusion is configured on the fool-proof groove, and the plurality of plugs can be inserted into the plurality of jacks in one-to-one correspondence.

As further optimization, a first mark is arranged on the circumferential surface of the male connector, and a second mark corresponding to the first mark is arranged on the circumferential surface of the female connector.

As a further optimization, the first identifier and the second identifier are both arrow identifiers.

As a further optimization, the mounting groove has an arc-surface side wall and a plane side wall, and the fool-proof protrusion is configured on the plane side wall.

As a further optimization, the fool-proof protrusion is a convex rib arranged on the side wall of the mounting groove.

Preferably, a seal ring is fitted around a circumferential surface of the female connector, and the male connector is disposed on the female connector and is capable of sealing an end surface of the male connector with the seal ring.

By adopting the technical scheme, the utility model discloses can gain following technological effect:

the utility model discloses a signal harness is provided with multiple fool-proof structure, has fine fool-proof effect. Specifically, when the male connector is inserted into the female connector, the mounting groove of the D shape is butted with the mounting head matched with the mounting groove, and the fool-proof protrusion is butted with the fool-proof groove; and only if the installation groove and the installation head which meet the D type are consistent in angle and the fool-proof bulge and the fool-proof groove are corresponding, the male connector can be inserted into the female connector, and a plurality of plugs can be accurately inserted into a plurality of jacks one by one. Compared with the prior art, the signal wiring harness can effectively prevent the situation that the male connector and the female connector are inserted wrongly, and meanwhile, even if mounting grooves and mounting heads are mounted vigorously, multiple fool-proofing of fool-proofing bulges and fool-proofing grooves can also effectively prevent the wrong connection of the male connector and the female connector. In addition, in the present case, mounting groove and installation head to and prevent that slow-witted arch and prevent slow-witted recess prevent slow-witted simple structure, can not too much increase manufacturing cost.

Through the technical scheme, the signal wire harness can play a good fool-proof role through multiple fool-proof settings.
