Description

TECHNICAL FIELD [0001] The present invention relates to a joint connector and a manufacturing method thereof,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint connector for electrical connection and a method of manufacturing the same, and is intended for simultaneously connecting signals or electric outputs electrically common among electrical parts or in specific parts.

An electrical connector is used to connect a plurality of electric wires to each other in an electronic device. A plurality of electric terminals each of which is connected to an electric wire are arranged in one of the connectors, and electric terminals are arranged in the corresponding other connector. So that the terminals are brought into contact with each other so as to be energized. At this time, the coupling of the electric terminal constituting one of the connectors and the housing is performed such that when the electric wire connected to the electric terminal is pulled, the electric terminal is not separated from the housing, as described in Korean Utility Model Application No. 20-2008-0000867, A lance serving as a retainer supporting part protruding from the housing is inserted into the groove formed in the housing to prevent the escape of the lance or to form a groove on one side of the electric terminal and the housing as shown in Fig. 11 of Korean Patent Laid-Open Publication No. 10-2000-0011776 And an engaging member, which is fitted in the groove formed in the housing, is coupled from the outside to the electrical terminal so as to prevent the electrical terminal from coming off.

On the other hand, in the connection of the connector and the connector, the cross-sectional area of the connector to be inserted, which is generally used, is gradually increased, or the inner surface space of the connector for accommodating the other connector is gradually reduced, A groove is formed in one of the connectors and an elastic ring is formed in the other connector so that the coupling between the connectors is achieved by the engagement of the groove and the ring.

However, in the case of using the lance for long term use in an environment where vibrations are frequent, such as automobiles, the elasticity of the lance is limited by the fatigue caused by the vibration And the lance can not support the groove of the electric terminal, so that the electric terminal is detached from the connector, thereby breaking the electric connection.

The latching member for complementing the latching member can firmly fix the electric terminal and the housing, but at least one separate member is required for each connector. Thus, the productivity is reduced due to the time required for assembling the housing and the latching member in mass production. This is because the connector is a relatively small member, and as the electronic apparatus becomes more complicated, the frequency of use increases, which is a factor that greatly lowers the productivity. Further, a separate latching member is required for each connector when the connector is coupled with the connector, and the latching members are prepared differently according to the shape of the connector, so that the assembling work is troublesome.

On the other hand, in the coupling between the connector and the connector, the contact due to friction has a risk of loosening of the coupling in a vibration environment, so that stability of coupling is difficult to be guaranteed. Further, when the groove and the ring are formed and coupled to each other, or when a separate binding member such as a clamp is further provided, the housing has to have a complex shape or a separate binding member must be provided, . Further, as the space occupied by the connector increases due to the shape or binding member attached to the outside, there is a problem in that it is incompatible with the recent trend of manufacturing the product in a small size by installing it in the minimum space.

According to the embodiments of the present invention, it is intended to provide a joint connector that prevents detachment of an electric terminal inserted into a joint connector and prevents detachment of another coupled connector at the same time, thereby making the connection between the electric terminal and the connector more robust .

The joint connector according to the embodiments of the present invention may include a housing, a plurality of receptacle terminals provided in the housing, a plurality of receptacle terminals provided in the housing, electrically connected to the receptacle terminals, A retainer supporting portion formed to be inclined outwardly of the housing, a retainer formed at the retainer supporting portion, and a retaining portion formed at a position corresponding to the retainer of the housing and inserted into the retainer.

According to one example, the retainer supporting portion may be formed on one or both surfaces of the upper surface and the lower surface. For example, the retainer support portion may be formed at one end of the retainer support portion, the one end portion of the retainer support portion being coupled to the housing, and the retainer support portion being hinge rotatable about a portion coupled to the housing as a rotation axis. The retainer may be formed at a position for fixing the receptacle terminal or a position for fixing the tab terminal. Further, the retainer supporting portion and the retainer may be integrally formed with the housing.

According to one example, the housing and the retainer may be formed integrally with the retainer when the housing and the retainer are formed, and may be connected to the retainer.

According to an example, a hook may be formed on the hook. For example, the latching jaw may be formed inside or outside the latching portion. Further, a chamfer is formed on the latching jaw, and a taper which is brought into contact with the retaining part when the retainer is inserted into the retaining part can be formed larger than a taper where the retainer comes into contact with the retaining part when releasing.

According to an exemplary embodiment, a tab cover may be provided, which is selectively coupled to one side of the housing and closes a surface of the housing where the tab terminal is exposed to the outside.

According to an embodiment of the present invention, there is provided a clip coupled to the housing to fix the housing to an object to be installed, and a clip holder part to which the clip is coupled may be formed on one side of the housing. For example, the clip holder portion may be formed on one or both of the upper surface and the lower surface of the housing.

According to one example, the housing may be composed of two housings which are formed separately from each other to be engageable with each other.

According to another aspect of the present invention, there is provided a joint connector including at least one terminal for connecting external signals, at least one signal connection part connected to an external signal, and at least one signal connection part for connecting the terminal and the signal connection part, And can be formed with a housing capable of double fixing.

According to one example, the double fixed structure may be composed of a lance of the signal connection part and a retainer formed integrally with the housing. Here, the signal connection unit cover may cover the signal connection unit. For example, the signal connection cover may be integrally formed with the housing. The housing may be formed of two housings which are detachably coupled to each other.

According to another aspect of the present invention, there is provided a method of manufacturing a joint connector, comprising the steps of: providing a housing; inserting a tab terminal into the housing; inserting one or more receptacle terminals into the housing; And the receptacle terminal is first fixed by the housing and the lance, and the receptacle terminal is secondarily fixed by the retainer provided in the housing.

As described above, according to the embodiments of the present invention, it is possible to effectively prevent the detachment of the electric terminal and / or other connector inserted into the joint connector, and to make the coupling more robust.

Further, according to the embodiments of the present invention, the receptacle terminal or the tab terminal can be doubly fixed inside the housing, so that the connection of the terminals can be made more robust.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments will be described in detail with reference to the accompanying drawings, but the present invention is not limited to or limited by the embodiments. In describing the embodiments, a detailed description of well-known functions or constructions may be omitted so as to clarify the gist of the present invention.

Hereinafter, a joint connector 10 according to one embodiment of the present invention will be described in detail with reference to FIGS. 1 to 4. FIG. 1 to 4 are views for explaining a joint connector 10 according to an embodiment of the present invention. Fig. 1 is an exploded perspective view of a joint connector 10 according to an embodiment of the present invention, Fig. 2 is a front perspective view of the joint connector 10 of Fig. 1, And FIG. 4 is a cross-sectional view of the joint connector 10 of FIG. Here, the joint connector 10 described with reference to Figs. 1 to 4 may be a 14-pin connector. However, the present invention is not limited by the drawings, and the number of pins can be substantially varied.

Referring to the drawings, a joint connector 10 includes a housing 11 having a receptacle terminal 18 and a tab terminal 17 therein, and a retainer support portion 12 having a retainer 121 formed therein. A clip 16 for fixing the housing 11 to the installation object and a tab cover 15 for selectively closing the portion where the tab terminal 17 is exposed in the housing 11. [

Hereinafter, for convenience of explanation, the 'upper surface' in the housing 11 refers to the upper surface in the state shown in FIG. 1, and the lower surface refers to the upper surface to be opposed to the upper surface. The direction in which the retainer 121 or the engaging portion 14 is formed in the housing 11 is referred to as a "longitudinal direction" and the direction perpendicular to the longitudinal direction is referred to as a "width direction".

The housing (11) is formed such that the receptacle terminal (18) and the tab terminal (17) can be inserted therein.

A retainer 121 for fixing the receptacle terminal 18 is formed on either or both of the upper surface or the lower surface of the housing 11. For example, the retainer support portion 12 is formed at a predetermined height in the outward direction at the first end portion 11a of the housing 11, and a retainer 121 is formed at an end portion of the retainer support portion 12 . Here, the housing 11, the retainer supporting portion 12, and the retainer 121 may be integrally formed. For example, the housing 11, the retainer support 12, and the retainer 121 can be manufactured by injection molding. The housing 11 is integrally formed with a retainer 121 on one side of the housing 11 in order to facilitate the injection of the retainer 121 when the housing 11 and the retainer support 12 and the retainer 121 are integrally formed by injection molding. And a protrusion 143 connected to the retainer 121 may be formed. The projections 143 are formed to be connected to each other when the retainers 121 and the housing 11 are injected and can be separated from the projections 143 in the process of inserting the injector retainer 121 into the insertion portion of the housing. The projecting portion 143 serves to smoothly supply resin to the retainer 121 when the retainer 121 is injection-molded.

The retainer support 12 is formed to be engageable with the housing 11 such that one end of the retainer support 12 is coupled to the first end 11a of the housing 11, And may have a hinge structure that operates as a rotating shaft and a supporting point. At the other end of the retainer supporting portion 12, a retainer 121 is formed which is coupled to the housing 11. Further, the retainer supporting portion 12 may have an elastic force in its own shape. In addition, the shape of the retainer supporting portion 12 can be formed such that the portion starting from the first end portion 11a is thinner and thicker toward the end of the retainer 121 side. A portion of the retainer support 12, which serves as a hinge through this configuration, prevents cracks from occurring in the rotational movement about the hinge axis. In addition, the retainer 121 may be formed long along the width direction of the housing 11.

The retainer supporting portion 12 serves to support the retainer 121 and the elasticity of the retainer supporting portion 12 itself is set such that the retainer 121 elastically supports the retainer 121 when the retainer 121 is engaged and disengaged from the housing 11 It plays a role. However, the shape and position of the retainer support 12 are not limited by the drawings, and the shape and position of the retainer support 12 can be substantially varied.

The housing (11) is formed with a locking portion (14) so that the retainer (121) can be fitted and fixed. For example, the engaging portion 14 may be formed in a groove formed along the width direction of the housing 11 at a position corresponding to the retainer 121 in the housing 11. [ In addition, the latching jaw 141 may be formed on one side of the latching part 14 to prevent the retainer 121 from being inserted and removed. For example, the retainer 121 has a structure in which one end of the retainer 121 is hooked or engageable with a step. In the retaining portion 14, an end portion of the retainer 121 is engaged with the end portion of the retainer 121, The stopper 141 can be formed. However, the shape and position of the latching jaw 141 are not limited to those shown in the drawings, and the latching jaws 141 may be discontinuously formed or may be formed at any position within the latching portion 14. [ Alternatively, the engaging jaw 141 may be formed at a position other than the inside of the engaging portion 14.

A chamfer part 142 guiding the insertion and release of the retainer 121 can be formed in the engaging jaw 141. The chamfered portion 142 is formed in the engaging step 141 to facilitate insertion and release of the retainer. The taper of the chamfered portion 142, which is to be brought into contact with the retainer when the retainer is inserted into the engagement portion 14, is made larger than the taper which is brought into contact with the release portion. With this structure, the force required for disengagement is greater than the force required for insertion. However, the present invention is not limited thereto, and the shape and position of the engaging portion 14, the engaging step 141 and the chamfered portion 142 can be substantially varied.

A tab terminal (17) is inserted into the housing (11). And the receptacle terminal 18 is inserted into the housing 11 to be engaged with the tab terminal 17. [ For example, the tab terminal 17 is inserted from the second end 11a of the housing 11 toward the first end 11b, and the receptacle terminal 18 is connected to the first end 11a of the housing 11, Lt; / RTI > Although only one receptacle terminal 18 is shown in the drawing, the present invention is not limited thereto, and a plurality of receptacle terminals 18 are provided.

Here, the joint connector 10 is a component for simultaneously connecting signals or electric outputs that are electrically common among the electric parts or in a specific part. The joint connector 10 also serves to receive signals from the outside of the joint connector by means of the receptacle terminals 18 and to form the circuit by connecting the specific receptacle terminals 18 to the tap terminals 17. [ For example, some of the receptacle terminals 18 may be connected to the battery of the vehicle, and the remaining receptacle terminals 18 may be connected to other devices such as lamps, Power can be applied to the power supply 18. The receptacle terminal 18 is inserted into the housing 11 and is formed of a conductive plate material so as to be electrically connected to an electric wire provided at one end of the housing 11 on the side of the first end 11a, .

The tab terminals 17 are provided along the longitudinal direction of the housing 11. Here, a plurality of tab terminals 17 may be provided in one housing 11. The receptacle terminals 18 are electrically coupled to the respective tab terminals 17. The receptacle terminals 18 have electric signals commonly in accordance with the associated tab terminals 17 so that they can have a common signal as many as the number of the tab terminals 17 in one connector. The circuit constituted by the tab terminal 17 can be varied depending on which receptacle terminal 18 is connected to the tab terminal 17. [

The joint connector 10 according to the embodiments of the present invention is formed such that the receptacle terminal 18 can be inserted therein and can be doubly fixed to the inside of the housing 11. [ For example, when the receptacle terminal 18 is inserted into the housing 11, the lance of the receptacle terminal 18 is caught by the step of the inside of the housing 11 and is firstly fixed. When the retainer 121 is inserted into the engaging portion 14, the retainer 121 is fixed in a secondary position to prevent the portion of the receptacle terminal 18 from being detached from the direction in which the receptacle terminal 18 can be removed.

Although the present invention has been described with reference to the case where the retainer 121 is formed to fix the receptacle terminal 18 in the present embodiment, the present invention is not limited thereto. As shown in FIG.

When the receptacle terminal 18 is inserted into the housing 11, the fixing and the manufacturing are completed and the detachment of the receptacle terminal 18 assembled by the housing 11 and the retainer 121 is prevented, The number of parts can be reduced and the manufacturing process of the joint connector 10 can be reduced. As a result, the productivity can be improved as the assembly work is performed quickly. Further, the retainer 121 can confirm whether the receptacle terminal 18 is coupled to the inside of the housing 11 in a proper position, thereby preventing occurrence of defects during assembly.

On one side of the housing 11, a tab cover 15 may be provided to close the surface of the tab terminal 17 exposed to the outside. For example, the tab cover 15 is formed to be able to close the second end 11b of the housing 11. The tab cover 15 may have a substantially "A" shape that is joined to the bottom surface of the housing 11 and the rear surface 151 closing the second end 11b of the housing 11. In addition, the tab cover 15 may be detachably attached to the housing 11. For example, a predetermined engagement groove 155 is formed in the side surface 152 of the tab cover 15 which is coupled to the side surface of the housing 11, and the engagement groove 155 is formed in the side surface of the housing 11 A cover engaging portion 115 protruding to a predetermined height may be formed. However, the present invention is not limited to the drawings, and the shape of the tab cover 15 and the coupling means with the housing 11 can be substantially varied.

The clip 16 is provided on either or both of the upper surface and the lower surface of the housing 11 to fix the housing 11 to the installation target. A clip holder portion 13 is formed on the housing 11 so that the clip 16 can be engaged. For example, the clip 16 may be formed so as to be slidable to the housing 11. Specifically, the clip 16 is formed with a holder coupling portion 161 having a predetermined plate shape, and the clip holder portion 13 is formed in a shape of a letter 'A' such that the holder coupling portion 161 can be inserted and slidably moved May be formed in the shape of a flange which is formed in such a manner that the protrusions of the protrusions face each other. A stopper 113 for restricting the movement of the clip 16 inserted into the clip holder 13 may be formed in the housing 11. Further, a grip portion 162 for gripping may be formed on the clip 16. However, the shape of the clip 16 is not limited by the drawings, and the shape and size of the clip 16 may be substantially varied.

On the other hand, unlike the embodiment described with reference to Figs. 1 to 4, the housing can be separated vertically. Hereinafter, the joint connector 20 having a separate housing will be described in detail with reference to FIGS. 5 and 6. FIG. Since the joint connector 20 according to the embodiments described below is substantially the same except that the housing 21 is separated, substantially the same components as those of the above-described embodiment are designated by the same names and reference numerals , And redundant explanations are omitted.

The joint connector 20 includes a housing 21 in which a receptacle terminal 28 and a tab terminal 27 are inserted and a retainer support portion 22 in which a retainer 221 is formed. A clip (26) for fixing the joint connector (20) to an object to be installed may be provided on one side of the housing (21).

The joint connector 20 may be formed by coupling one housing 21 or two housings 21 to each other. For example, as shown in FIG. 5, the housing 21 may be formed such that a tap terminal 27 of one layer is inserted therein. As shown in FIG. 6, it is possible to form one joint connector 20 by vertically coupling the housings 21 formed symmetrically with each other and into which the tap terminals 27 of one layer are inserted .

Here, the housing 21 may be formed to be completely symmetrical with respect to each other, or may be formed asymmetrically with respect to each other. However, the housing 21 can be changed in various ways as long as the housing 21 can be coupled to each other on a surface facing each other.

A retainer 221 for fixing the receptacle terminal 28 is formed on one or both of the housings 21. A retainer support 22 is formed at an end portion of the housing 21 at a predetermined height in the outward direction and a retainer 221 is integrally formed with the retainer support 22 at the end of the retainer support 22. [ . For example, the housing 21, the retainer support 22, and the retainer 221 can be integrally manufactured by injection molding. The housing 21 is integrally formed with one side of the retainer 221 so as to smooth the injection of the retainer 221 when the housing 21 and the retainer support 22 and the retainer 221 are injection- And a protrusion 243 connected to the retainer 221 may be formed. The projecting portion 243 serves to smoothly supply resin to the retainer 221 at the time of injection molding.

The retainer support 22 may have a hinge structure in which one end of the retainer support 22 is engaged with one end of the housing 21 to act as a rotation shaft and a support point. A retainer 221 coupled to the housing 21 is formed at the other end of the retainer support 22. For example, the portion of the retainer supporting portion 22 starting from the first end portion 21a may be thinner and thicker toward the end of the retainer 221 so that the retainer supporting portion 22 has an elastic force in its own shape. Further, the retainer 221 may be formed long along the width direction of the housing 21. The elasticity of the retainer supporting portion 22 itself serves to elastically support the retainer 221 when the retainer 221 engages and disengages from the housing 21. [ However, the shape and position of the retainer support 22 are not limited to those shown in the drawings, and the shape and position of the retainer support 22 may be substantially varied.

The housing 21 is formed with a retaining portion 24 so that the retainer 221 can be fitted and fixed. For example, the latching portion 24 may be formed in a groove corresponding to the retainer 221 in the housing 21 and formed in a long length along the width direction of the housing 21. [ In addition, the latching jaw 241 may be formed on one side of the latching part 24 to prevent the retainer 221 from being inserted and removed. For example, the retainer 221 may have a structure in which a hook or an engageable step is formed at one end thereof, and the engaging jaw 141 may be a step formed at a position where the hook structure of the retainer 221 can be engaged. The latching jaw 141 may be provided with a chamfered portion 242 for guiding the insertion and release of the retainer 221 easily. However, the present invention is not limited thereto, and the shapes and positions of the latching portion 24, the latching jaw 241, and the chamber portion 242 may be substantially varied.

A tab terminal 27 is inserted into the housing 21 and a receptacle terminal 28 is inserted into the housing 21 to be coupled with the tab terminal 27. Although only one receptacle terminal 28 is shown in the drawing, the present invention is not limited thereto, and a plurality of receptacle terminals 28 are provided.

The tab terminals 27 are provided along the longitudinal direction of the housing 21. Here, a plurality of tab terminals 27 may be provided in one housing 21. The receptacle terminals 28 are electrically coupled to the respective tab terminals 27. [ The receptacle terminals 28 have electrical signals commonly in accordance with the associated tab terminals 27 so that they can have a common signal as many as the number of tab terminals 27 in one connector. The circuit constituted by the tab terminals 27 may vary depending on which receptacle terminal 28 is connected to the tab terminal 27. [

The joint connector 20 according to the embodiments of the present invention is formed such that the receptacle terminal 28 can be inserted therein and can be doubly fixed to the inside of the housing 21. [ For example, when the receptacle terminal 28 is inserted into the housing 21, the lance of the receptacle terminal 28 is caught by the step inside the housing 21 and is firstly fixed. When the retainer 221 is inserted into the engaging portion 24, the retainer 221 is fixed in a second position to prevent the portion of the receptacle terminal from being detached from the direction in which the receptacle terminal can be removed.

When the receptacle terminal 28 is inserted into the housing 21, the fixing and the manufacturing are completed and the detachment of the receptacle terminal 28 assembled by the housing 21 and the retainer 221 is prevented, The number of parts can be reduced, the manufacturing process of the joint connector 20 can be reduced, and the productivity can be improved as the assembling operation is performed quickly. Further, the retainer 221 can confirm whether the receptacle terminal 28 is coupled to the inside of the housing 21 in a proper position, thereby preventing occurrence of defects during assembly.

The clip 26 is provided on either or both of the upper surface and the lower surface of the housing 21 to fix the housing 21 to the installation object. A clip holder portion 23 is formed in the housing 21 so that the clip 26 can be engaged with the clip holder 26. The clip holder 26 has a holder coupling portion 261 having a predetermined shape to be coupled to the clip holder portion 23, And the grip portion 262 may be formed. However, the shape of the clip 26 is not limited by the drawings, and the shape and size of the clip 26 can be varied substantially.

Although not shown in the drawing, a tab cover (not shown) for selectively closing a portion of the housing 21 where the tab terminal 27 is exposed may be provided.

Although the housing and the tab cover are separately formed and fastened in a detachable manner in the above embodiments, the present invention is not limited thereto, and the tab cover can be formed integrally with the housing. For example, the tab cover may be integrally formed with the housing, and one side of the tab cover may be coupled to the housing so as to selectively expose the tab terminals. For example, a tab cover formed similarly to that shown in FIG. 1 is coupled to a side surface of the housing using a predetermined hinge shaft or a rotation shaft, and the tab cover rotates to one of the upper and lower surfaces of the housing The tap terminals can be exposed or closed. Alternatively, the tab cover may have a plate shape capable of closing only the surface on which the tab terminals are exposed in the housing. In this case, it is possible to expose or close the surface to which the tab terminal is coupled as the plate rotates as one side edge is coupled to the housing and the coupled portion becomes the hinge axis. In this case, it is also possible to provide a holding mechanism for holding the plate-shaped tab cover in a state fixed to the housing. In another embodiment, the tab cover can be formed to be slidable or engageable with the housing. Here, the present invention is not limited thereto, and the shape and the shape of the tab cover can be changed substantially in various ways.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. For example, it is to be understood that the techniques described may be performed in a different order than the described methods, and / or that components of the described systems, structures, devices, circuits, Lt; / RTI > or equivalents, even if it is replaced or replaced.
