Description

{INTEGRATED JOINT CONNECTOR}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an integral joint connector capable of providing a signal electrically common between electric component parts in a vehicle or the like or electrically connecting to each other.

The connector has a purpose of electrically connecting different power components to the power source of the vehicle. To this end, the connector is usually comprised of an arm and a male connector, and a housing of each connector may be connected with a wiring sub or, for example, a tap terminal or the like. Then, when the male and female connectors are fitted to each other, the wiring sub can be electrically connected to each other with the tab terminal as an intermediate medium.

However, manufacturing and assembling the connector by separating the connector into the male and female connectors as in the prior art increases the number of parts, thereby increasing the maintenance cost and the overall production cost. In addition, a step of assembling and fastening the female and male connectors is added, resulting in a higher defect rate and at the same time lowering the productivity.

In a connector used in a vehicle or the like, unintentional release of electrical connection to some electrical components can have a serious safety impact. So, quality control is especially important. For this purpose, for example, a release preventing member or the like which can prevent the wiring sub to be separated from the connector is used. However, in the conventional release preventing member, a worker has to manually work to be able to fasten, and in particular, a fastening failure such as less fastening by an immature worker has occurred.

In addition, even when the fastening operation is completed, the operator has had to check one by one with naked eyes in order to check whether there is a defect. Also, even when the release preventing member is completely fastened to the connector, if the external force is applied, the release preventing member can be detached from the connector and thus there is a problem of quality reliability.

Korean Registered Utility Model No. 20-0453565 (Registered on May 2, 2011) Korean Registered Patent No. 10-1613695 (Registered on April 12, 2016) Japanese Patent Laid-Open Publication No. 08293353 Japanese Patent Application Laid-Open No. 2007220362

The embodiments of the present invention have been made to solve the above problems,

The housing of the connector is formed in a single piece to reduce the number of parts, reduce the production cost, and reduce the number of assembly processes.

Also, the rigid fixation of the wiring sub serves to fundamentally prevent the wiring sub from being disconnected from the connector. That is, the wiring sub allows the electrical connection state to be maintained even if an external impact such as vibration or dropping is applied to the connector.

According to an embodiment of the present invention, A conductive tab terminal disposed in the housing; A tipper member coupled to the housing in a direction orthogonal to the tap terminal and fixing the wiring sub; And a rear holder which is fastened to the housing such that at least the exposed portion of the tap terminal and the tipper member is covered.

The typhoid member includes a latching protrusion formed on one side or both sides thereof, and the housing includes an end stop corresponding to the latching protrusion.

The latching protrusions are sequentially spaced apart from each other in the orthogonal direction; And a second latching protrusion.

The wiring sub is inserted and electrically connected to the tap terminal at a first locking position in which the tip end member is located between the first and second locking protrusions.

So that the wiring sub is fixed at a second locking position in which the tip end member is further pressed in the orthogonal direction at the first locking position so that the second locking projection is located below the end jaw.

The rear holder may further include a guide plate slidable along an upper surface of the housing in which the typhoid member is disposed.

The housing may further include a guide jaw for guiding movement of the guide plate.

At least one rib may be formed in the guide plate in a predetermined pattern.

The side plate may have a fastening protrusion formed on both sides of the housing, and the rear holder may have a fastening protrusion corresponding to the fastening protrusion.

The housing may be injection-molded into a single piece.

The tap terminal may be press-fitted into the housing.

A rear holder coupled to a housing of an integral joint connector, comprising: a rear plate covering one side of the housing into which a tap terminal is inserted; A side plate connected to the rear plate so as to surround both sides of the housing; And a guide plate vertically connected to the rear plate and the side plate to cover an upper surface of the housing, respectively.

The rear plate may be formed with a relief pattern that contacts each end of the tab terminal exposed to fix the tab terminal.

The side plate may be formed with a slit-shaped engagement hole in the direction of reciprocation of the rear holder.

As described above, according to the present invention, various effects including the following can be expected. However, the present invention does not necessarily achieve the following effects.

According to the present invention, the housing can be formed as a single unit, which is separated from the conventional arm / male housing and used to reduce the number of parts, reduce the production cost, and improve the productivity by reducing the assembling process.

Further, the tipper member can be fixed to the housing at the first locking position, and a wiring sub can be inserted and electrically connected to the tap terminal. In addition, the tipper member can secure the wiring sub at the second locking position to effectively prevent the wiring sub from being disengaged.

Then, the rear holder can detect whether or not the tipper member is not engaged in the second locking position. In other words, the rear holder can be assembled to the housing only when the tipper member is completely fastened, so that the quality of the connector can be expected to be improved.

Further, when the rear holder is fastened to the housing, the exposed portions of the tipper member and the tap terminal are covered to prevent the respective components from being separated from each other. As a result, it is possible to prevent the tip portion from being detached even if an external impact such as vibration or drop is applied to the connector coupled with the wiring sub.

Further, the rear holder can reinforce rigidity against shrinkage and warpage by forming ribs on at least one surface constituting the rear holder.

The tip portion (30) has a locking protrusion (32) formed on one side or both sides thereof. The latching protrusion 32 allows the tippea member 30 to be engaged with the seating groove 16 described above. At this time, the latching protrusion 32 is constituted by the first latching protrusion 32a and the second latching protrusion 32b which are arranged to be spaced apart from each other in the orthogonal direction to the tap terminal 20, and these latching protrusions 32 are sequentially arranged. This makes it possible to make a double lock when the typhoid member 30 is coupled to the housing 10.

FIG. 7 is a perspective view showing the first locking position, FIG. 8 is a sectional view taken along the line a-a 'of FIG. 7, and FIG. 9 is a sectional view taken along the line bb' of FIG. Referring to Figs. 7 to 9, the first latching protrusion 32a and the second latching protrusion 32b allow the tipyear member 30 to be locked in two steps. Specifically, when the typhoid member 30 is inserted into the seating groove 16, the first latching protrusion 32a is first brought into contact with the stepped portion 12. At this time, when the presser member 30 is pressed and further pressed, the first latching protrusion 32a passes over the step 12.

As a result, the step 12 is located between the first latching protrusion 32a and the second latching protrusion 32b, which is hereinafter referred to as a first locking position. The tip portion member 30 is not completely received in the seating groove 16 in the first locking position but partially protruded upward in the seating groove 16. [

The tip portion member 30 has the effect of being locked at the same time while being mounted on the housing 10 in the first locking position. The wiring sub 50 is then inserted into the housing 10 at the first locking position and is electrically connected to the tap terminal 20.

At this time, the guide plate 42 is vertically connected to the rear plate 46 and the side plate 44 so as to cover all or part of the upper surface of the housing 10.

In this side plate 44, a coupling hole 45 is formed in the direction of reciprocating sliding movement of the rear holder 40. The shape of the coupling member 45 is, for example, a slit shape.

The rear holder 40 according to one embodiment is slid in the other side direction from one side of the housing 10 in which the tab terminals 20 are inserted. At this time, the guide plate 42 is guided by the guide jaws 14 to cover the upper surface through which the tip portion 30 is exposed. Conversely, the rear holder 40 can slide in the opposite direction and be detached from the housing 10.

The rear plate 46 may be provided with a relief pattern 47 which contacts each end of the exposed tap terminal 20 to prevent fine movement of the tab terminal 20. [ On the other hand, the rear holder 40 is preferably integrally formed by injection molding or the like.

Next, a state in which the wiring sub 50 is inserted and coupled to the integral joint connector according to one embodiment will be described. First, at the second locking position, the wiring sub 50 is engaged and fixed by the fixing piece 34 of the insertion hole 36. To this end, a terminal 52 having a groove of a predetermined shape may be formed at the end of the wiring sub 50.

Therefore, the typhoid member 30 is stably held in the seating groove 16 until it is covered by the guide plate 42 of the rear holder 40 at the second locking position to release the engagement of the rear holder 40. [ The coupling state can be maintained.

When the rear holder 40 is fastened to the housing 10, both sides of the guide plate 42 are fitted between the guide tabs 14 and the rear plate 46 is fastened to the housing 10, Which is in close contact with one side surface of the base 10. Further, the engaging member 45 is engaged with the side-surface projecting portion 18 at the second locking position, in particular, to prevent the rear holder 40 from being detached and detached. The side plate 44 may further include a chamfer 14a corresponding to the chamfer 14a formed in the side surface projection 18. [
