Abstract
The utility model discloses a connecting piece of a vehicle wire harness. The connecting piece comprises an insulated housing and signal connecting columns. The insulated housing is cylindrical, an external part of the insulated housing is provided with a flange, and a middle part of the insulated housing is provided with three signal connecting columns which are arranged in a straight line. An annular groove is arranged on each of the signal connecting columns. The insulated housing is fixedly connected with the signal connecting columns through embedding the insulated housing in the annular grooves. One end of each of the signal connecting columns is a spherical shape, and a surface of each of the signal connecting columns is provided with an oxidation resistance film. The connecting piece of the vehicle wire harness has an integrated structure, which means that the signal connecting columns and the insulated housing are connected to form a whole body, thus the connecting piece has a solid structure, the signal connecting columns are unlikely loosened even after long time usage, and ideal electrical performance still can be maintained.
Description
Technical field
The utility model relates to a kind of connector of automobile-used wire harness.
Background technology
The connector of automobile-used wire harness can be used as the accessory that the automobile pressure sensor is installed; The connector of automobile-used wire harness is a modular construction in the prior art, promptly between its inner signal joint pin and the housing is to link together and form complete connector through follow-up artificial plug-in mounting.Signal joint pin external packets is wrapped with one deck insulating barrier, and this insulating barrier is connected with housing through interference fit, and then the signal joint pin is fixed on the housing.This structure makes that signal joint pin and housing are separation relation, and long-term the use between back signal joint pin and the housing is easy to generate the slit, and then the loosening phenomenon of signal joint pin occurs, influences the electric property of the connector of automobile-used wire harness.Therefore, there is the shortcoming that structural design is unreasonable, result of use is not good, the life-span is short in the connector of automobile-used wire harness of the prior art.
Summary of the invention
The technical problem that the utility model will solve provides a kind of connector of automobile-used wire harness of firm in structure, long service life.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: the connector of this automobile-used wire harness comprises insulation shell and signal joint pin; Said insulation shell is tubular, and its outside is provided with flange, and the middle part of said insulation shell is provided with three signal joint pins that are arranged in a straight line; Said signal joint pin is provided with annular groove; Said insulation shell is fixedly connected with the signal joint pin through being embedded in the annular groove, and said signal joint pin one end is a sphere shape, and said signal joint pin surface is provided with oxidation-resistant film.Insulation shell is embedded in the effect of playing the fixed signal joint pin in the annular groove, and then the signal joint pin is fixed on the insulation shell.The connector conduct and the plug-in unit of this automobile-used wire harness use, and will inevitably produce friction at signal joint pin place, and more smooth and easy for making use, an end of signal joint pin is a sphere shape, the resistance in the time of can effectively reducing the plug-in unit use like this.Electric current can cause the oxidation rapidly of signal joint pin surface during the work of signal joint pin, and this oxidation-resistant film can slow down oxidation rate, thereby the resistance value of signal joint pin is kept in the reasonable scope.
The utility model adopts technique scheme: it is that signal joint pin and insulation shell hold together that the connector of this automobile-used wire harness has integral structure; Make this connector have firm structure; Even the long-term back signal joint pin that uses also is difficult for becoming flexible, still can keep desirable electric property; Simultaneously, firm structure useful life of having improved the connector of this automobile-used wire harness.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the front view of the connector of the automobile-used wire harness of the utility model;
Fig. 2 is the cut-away view of the connector of the automobile-used wire harness of the utility model.
Embodiment
Like Fig. 1, shown in 2, the connector of automobile-used wire harness comprises insulation shell 1 and three signal joint pins 2.Insulation shell 1 is tubular, and the outside is provided with flange; Inside is provided with enclosure portion, thereby the cross section of insulation shell 1 is " worker " shape, and this enclosure portion makes 1 inner the branch for two chambers of insulation shell, and is not communicated with between two chambers.Three signal joint pins 2 are positioned at the closed part of insulation shell 1, and linearly shape is arranged.The signal binding post is provided with annular groove 3 in the centre position, it is with after insulation shell 1 is connected, and insulation shell 1 is embedded in the groove, and the signal binding post has been fixed on the insulation shell 1 thus.At signal joint pin 2 one ends is sphere shape, and this structure can provide resistance less joint face in use, and the connector of this automobile-used wire harness very easily is connected with other parts.Every signal joint pin 2 surfaces all are provided with oxidation-resistant film, and this oxidation-resistant film is a silver layer, can play the effect that delays oxidation.
