Description

Connector {CONNECTOR}

The present invention relates to a connector, and more particularly, to a connector provided with a front holder in a housing.

In general, a connector assembly is a connection part that electrically connects a power source and a device, a device and a device, and the interior of the device. This connector assembly consists of a pair of matable and detachable, for example, a male connector and a female connector. In addition, a plurality of terminals for transmitting current and signals are provided inside the connector.

In the connector assembly, the first connector and the second connector are coupled to each other to perform electrical connection. Electrical coupling between the first connector and the second connector is achieved by coupling terminals in each of the inner terminals.

However, if the terminal is not properly inserted into the connector, the electrical connection between the terminals is not established even when the connector is coupled, so that the operation of the corresponding electronic component is not performed properly.

In order to prevent this problem in advance, a front holder is inserted inside the connector to align the terminals inside the connector and fix the position. When the front holder is inserted into the connector and first fastened to be temporarily fixed, a plurality of terminals are inserted into the connector. When a plurality of terminals are inserted into the connector, more force is applied to the front holder to be secondarily fastened, and the terminals are fixed by the front holder to prevent separation.

The front holder is inserted into the connector and fixed in a wide variety of ways. Among them, there is a connector provided with a front holder that is firstly fastened to be inserted from the front of the connector and temporarily fixed, and that is secondarily fastened when the front holder is pushed to the side.

In the connector provided with the front holder having such a fastening method, a guide groove is formed in the terminal portion into which the terminal is inserted so that the front holder slides inside the connector. When manufacturing a connector, a mold core is inserted into the side of the connector housing to form a guide groove. As the mold core is mounted, an opening slit is formed on the side of the housing. Since the opening slit is structurally unavoidably formed to form a guide groove in the housing, it is not a factor affecting the performance of the connector.

However, conventionally, when the mating connector is inserted into the connector, the mating connector is caught in the opening slit due to the opening slit formed on the side of the connector housing, so that the mating connector is not properly fastened, or the connector is fastened only when an excessive insertion force is applied. There was a problem. In addition, in the process of excessively applying the insertion force, the housing of the connector is damaged, and thus the terminal inserted into the housing is damaged.

A temporary coupling groove and a complete coupling groove are formed side by side at a predetermined distance apart from the outer surface of the terminal insertion part, and the terminal can be inserted when the front holder is caught in the temporary coupling groove, and the inserted terminal when the front holder is caught in the complete coupling groove Is fixed.

The front holder has a front plate covering the front surface of the terminal insertion part, a top plate orthogonal to the front plate, and having a guide protrusion seated on a guide rail formed on one side of the terminal insertion part, and orthogonal to the front plate, A lower plate facing the upper plate and having a guide protrusion seated on the guide rail formed on the other side of the terminal insertion part, and the front plate, the upper plate, and the lower plate are all orthogonal to each other, and the upper plate and the lower plate are connected Includes a side plate to let.

The upper plate has a coupling protrusion protruding toward the lower plate, and the coupling protrusion is seated in the temporary coupling groove or the complete coupling groove according to the movement of the front holder.

A guide receiving rib is formed on the side plate in parallel with the upper and lower plate, and a plurality of separation preventing protrusions protrude toward the lower plate on the guide receiving rib.

A plurality of entry rails, which are passages into which the departure prevention protrusions are inserted, are formed on the front surface of the terminal insertion unit, and a guide rail communicating in a direction perpendicular to the entry rail is formed inside the terminal insertion unit.

In the connector according to the present invention, the following effects can be obtained.

According to the present invention, a first core hole and a second core hole are formed in the upper and lower portions based on the guide channel formed in the housing. Since the core hole is not formed in the guide channel, the problem of being caught on the edge of the core hole in the process of inserting the mating connector into the connector is solved, and there is an effect that the connection between the connectors is smoothly performed.

According to the present invention, the front holder is assembled to the front surface of the housing, and is temporarily assembled or completely assembled along the guide rail formed by the slide core inserted into the core hole. Accordingly, since the direction in which the front holder is assembled with the housing and the direction in which it is temporarily coupled or completely coupled to the housing are orthogonal to each other, there is an effect that the front holder is arbitrarily pressed by external pressure to prevent complete assembly.

Referring to FIG. 4, the exterior of the connector 10 is constituted by a housing 11. The housing 11 is manufactured by injection molding a resin of an insulating material. An inner space 11 ′ with one side open is formed inside the housing 11. The mating connector 40 is coupled to the open portion of the inner space 11'. A terminal insertion portion 20 is formed in the inner space 11'. The terminal insertion unit 20 will be described in detail later.

Guide channels 12 are formed on both side surfaces of the housing 11 in parallel with the direction in which the inner space 11 ′ is opened. The guide channel 12 is formed in a direction to widen the entrance of the inner space 11 ′, and both outer surfaces of the housing 11 protrude to correspond to the shape of the guide channel 12. A guide protrusion 41 corresponding to the guide channel 12 may protrude from the mating connector 40, and the guide protrusion 41 moves along the guide channel 12 to form an internal space of the connector 10. The mating connector 40 is guided to (11').

A first core hole 13 and a second core hole 14 are formed in the upper and lower portions of the guide channel 12, respectively. The first core hole 13 and the second core hole 14 are inserted to form guide rails 23, 24, 25 in the terminal insertion part 20 when the housing 11 is injection-molded. do. The front holder 30 moves along the guide rails 23, 24, and 25, and the front holder 30 is temporarily coupled or completely coupled to the housing 11.

Meanwhile, the connector 10 constituting the embodiment of the present invention has a structure in which the front holder 30 is moved in a direction perpendicular to the direction in which the terminal is inserted in the inner space 11 ′. Core holes for configuring the rails 23, 24, and 25 are necessarily created. Conventionally, a core hole formed in the housing 11 is formed up to the guide channel 12 to prevent the coupling with the mating connector 40.

However, the positions of the first core hole 13 and the second core hole 14 of the present embodiment may be changed according to the shape and size of the terminal insertion part 20 and the front holder 30, , It is not formed across the guide channel 12. When the first core hole 13 or the second core hole 14 is formed so as to cross the guide channel 12, the first core hole 13 or the second core hole 14 is inserted into the inner space 11 ′. This is because the mating connector 40 is caught on the edge of the one core hole 13 or the second core hole 14 so that the connector 10 is not properly coupled.

A terminal insertion part 20 into which a terminal is inserted is formed in the inner space 11'. The outer shape of the terminal insertion part 20 is formed by the insertion part body 21. The insertion body 21 is formed to face the open portion of the inner space 11'. The insert body 21 has a shape corresponding to the cross-sectional shape of the inner space 11 ′, and is formed to be spaced apart from the inner wall of the first housing 11 at a predetermined distance.

A plurality of terminal holes 21 ′ are formed in the insertion body 21 to pass through the front and rear surfaces of the housing 11. A terminal is inserted into the terminal hole 21'. The shape and number of the terminal holes 21 ′ may be changed according to the type and shape of the connector 10.

In detail, the hook jaw 22 is protruding from the inner edge of the insertion portion body 21 toward the inner side of the first housing 11, and the insertion portion body ( 21) and a step is formed. The hooking jaw 22 supports the front end of the front holder 30 to prevent the front holder 30 from entering the inner space 11' any more.

A plurality of guide rails 23, 24, and 25 are formed in the insertion body 21 in a direction perpendicular to the direction in which the terminal is inserted. The plurality of guide rails 23, 24, 25 are formed by a mold core passing through the first core hole 13 and the second core hole 14. Specifically, a mold core is installed inside a mold made to form the exterior of the housing 11, and a liquid resin flows into the mold so that the plurality of guide rails 23, 24, 25) is formed. That is, the reason why the mold core is installed inside the mold is to form the plurality of guide rails 23, 24, 25 on the insert body 21, and the first core hole 13 and the second core The hole 14 serves as a passage for removing the mold core.

A first guide rail 23 is formed by a mold core inserted into the first core hole 13, and a second guide rail 24 is formed by a mold core inserted into the second core hole 14 do. The first guide rail 23 and the second guide rail 24 are elongated in a direction perpendicular to a direction in which a terminal is inserted on an outer surface of the insert body 21. In addition, a third guide rail 25 is formed by a mold core inserted into the second core hole 14. The third guide rail 25 penetrates approximately the center of the insert body 21 and is formed in parallel with the first guide rail 23 and the second guide rail 24.

A guide protrusion 32c and a departure prevention protrusion 34a of the front holder 30 are mounted on the plurality of guide rails 23, 24, and 25. Since the guide protrusion 32c and the departure prevention protrusion 34a move along the first, second and third guide rails 23, 24, 25, the front holder 30 is the insertion part body 21 With respect to, relative motion can be performed in a direction perpendicular to the insertion direction of the mating connector 40.

A rib insertion hole 25 ′ is formed on the front surface of the insertion part body 21 to communicate with the third guide rail 25. The guide receiving rib 34 of the front holder 30 is inserted into the rib insertion hole 25'.

The third guide rail 25 is formed with several entry rails 25" branching in a direction perpendicular to the longitudinal direction of the third guide rail 25 toward the front of the insertion part body 21. The entry rail 25" is a passage through which the departure prevention protrusion 34a of the front holder 30 moves from the front surface of the insertion part body 21 to the third guide rail 25. The entry rail 25" is in communication with all of the third guide rail 25 and the rib insertion hole 25'.

On the outer surface of the front edge of the insert body 21, a temporary coupling groove 26 and a complete coupling groove 27 are formed side by side at a predetermined distance apart. The temporary coupling groove 26 and the complete coupling groove 27 are coupled with the coupling protrusion 32a of the front holder 30 to determine a coupling state between the front holder 30 and the housing 11. The temporary coupling groove 26 and the complete coupling groove 27 are inclined along the moving direction of the front holder 30 so that the coupling protrusion 32a is the temporary coupling groove 26 or the complete coupling groove ( It is easy to move to 27).

On the other hand, the positions of the temporary coupling groove 26 and the complete coupling groove 27 are not always formed on the outer surface of the front edge of the insert body 21. It may be formed at a position corresponding to the coupling protrusion 32a of the front holder 30 so that the front holder 30 can be temporarily coupled or completely coupled to the housing 10.

5, the front holder 30 is formed by a front plate 31, a top plate 32, a bottom plate 32', and a side plate 33 to form a coupling space 31'. The appearance is constructed. Specifically, the front plate 31 has a plate shape covering the front surface of the insert body 21, and the upper plate 32 has a plurality of terminal holes 31a corresponding to the terminal holes 21'. Is formed.

The front plate 31 is integrally formed with a top plate 32, a bottom plate 32', and a side plate 33 so as to be orthogonal to the front plate 31 along an edge, and the coupling space 31' Is formed surrounded by the front plate 31, the top plate 32, the bottom plate 32', and the side plate 33. The top plate 32 and the bottom plate 32' are arranged to face each other, and the side plate 33 is arranged to connect the top plate 32 and the bottom plate 32'. The front holder 30 has a shape in which a surface facing the side plate 33 and a surface facing the front plate 31 are open. Accordingly, at least two surfaces of the coupling space 31 ′ are open.

A portion of the upper surface plate 32 is cut at an edge to form a cantilever-shaped fixed elastic arm 32b. The fixed elastic arm 32b extends in a direction perpendicular to the direction in which the front plate 31 extends. A guide protrusion 32c protrudes toward the coupling space 31' at the front end of the fixed elastic arm 32b. When the front plate 31 of the front holder 30 contacts the front surface of the insert body 21, the guide protrusion 32c is seated on the first guide rail 23.

The coupling protrusion 32a protrudes toward the coupling space 31 ′ on the inner side of the top plate 32. The coupling protrusion 32a may have a semicircular cross-section to facilitate movement to the temporary coupling groove 26 and the complete coupling groove 27. The coupling protrusion 32a is formed at a location corresponding to the position of the temporary coupling groove 26 and the complete coupling groove 27. The coupling shape of the front holder 30 varies according to the shape in which the coupling protrusion 32a is coupled to the temporary coupling groove 26 or the complete coupling groove 27. A confirmation through hole 31b may be formed in the front plate 31 so that the coupling protrusion 32a is visible to correspond to the position where the coupling protrusion 32a is formed.

The lower plate 32 ′ is formed symmetrically to have the same shape as the upper plate 32. However, the coupling protrusion 32a is not necessarily formed on the lower plate 32 ′. The guide protrusion 32c formed on the lower plate 32' is seated on the second guide rail 24.

The side plate 33 is perpendicular to the front plate 31, the top plate 32, and the bottom plate 32'. The side plate 33 is integrally formed with the front plate 31 so that the top plate 32 and the bottom plate 32 ′ are connected. The side plate 33 interferes with the insertion part body 21 to limit the distance the front holder 30 moves. When the side plate 33 comes into contact with the side surface of the insert body 21, the front holder 30 stops moving.

A guide receiving rib 34 extends from the side plate 33 toward the coupling space 31 ′. The guide receiving rib 34 has a rib shape when viewed from the rear end of the front plate 31, but substantially has a plate shape like the upper and lower plates 32 ′. The guide receiving rib 34 is formed parallel to the top plate 32 and the bottom plate 32 ′, and is integrally formed by being connected to the front plate 31.

The guide receiving rib 34 has several separation preventing protrusions 34a protruding toward the lower surface 32 ′. The departure preventing protrusion 34a is formed to correspond to the number of the entry rails 25". The departure prevention protrusion 34a is seated on the third guide rail 25 through the entry rail 25”.

A pair of guide protrusions 32c and separation prevention protrusions 34a are respectively mounted on the first, second, and third guide rails 23, 24, and 25 to guide the movement of the front holder 30.

The guide receiving rib 34 has a receiving groove 34b opened toward the front plate 31, as can be seen in FIG. 6. Alignment pins 42 formed in the mating connector 40 are inserted into the receiving groove 34b. The alignment pin 42 of the mating connector 40 is inserted into the receiving groove 34b to induce coupling between the connectors 10.

In particular, guide protrusions 32c formed on the upper and lower surfaces 32 and 32 ′ are disposed to be seated on the first and second guide rails 23 and 24.

When the fixed elastic arms 32b formed on the top plate 32 and the bottom plate 32' come into contact with the insert body 21, the front plate is elastically deformed toward the inner surface of the housing 11 ( 31) is maintained until it comes into contact with the front surface of the insert body 21, and when it reaches the first guide rail 23 and the second guide rail 24, the deformation of the fixed elastic arm 32b is released. , The guide protrusion 32c is seated on the first guide rail 23 and the second guide rail 24. At the same time, the departure preventing protrusion 34a passing through the entry rail 25” is seated on the third guide rail 25. The shape in which the housing 11 and the front holder 30 are combined is shown in FIG. 6. In addition, the front end of the top plate 32, the bottom plate 32 ′, and the side plate 33 may span the hook 22 to support the front holder 30. Of course, all of the top plate 32, the bottom plate 32', and the side plate 33 can be supported by the hook 22, as well as the top plate 32 and the bottom plate 32'. And only one of the side plate 33 may be supported by the hook 22.

6, when the guide protrusion 32c and the departure prevention protrusion 34a are all seated on the first, second, and third guide rails 23, 24, and 25, the front holder 30 ) Moves along the guide rails 23, 24 and 25 in a direction perpendicular to the direction inserted into the housing 11 and may be temporarily coupled or completely coupled. That is, the front holder 30 may be moved in a direction parallel to the direction in which the first core hole 13 and the second core hole 14 are opened with respect to the housing 11.

The initial state in which the housing 11 and the front holder 30 are coupled is a temporary coupling state as shown in FIG. 7(a). In the temporary coupling state, the coupling protrusion 32a is seated in the temporary coupling groove 26. In addition, the departure preventing protrusion 34a is in a state in which it can escape from the third guide rail 25 through the entry rail 25”. However, since the guide protrusion 32c is seated on the first guide rail 23 and the second guide rail 24, it is not easily removed. In the temporary coupling state, the terminal is inserted into the terminal hole 21 ′ of the terminal insertion part 20.

When all of the terminals are inserted, the operator can switch the front plate 31 to the fully coupled state of FIG. 7(b) by pushing the front plate 31 in the direction of the arrow shown in FIG. In detail, when the front holder 30 receives a force in the direction of the arrow shown in FIG. 7 (a), a coupling protrusion 32a positioned in the temporary coupling groove 26 is formed in the temporary coupling groove 26. Riding a slope, exits from the temporary defect groove and moves to the complete coupling groove (27). At this time, the terminal hole 21 ′ formed in the housing 11 and the terminal hole 31a formed in the front holder 30 match each other, and the entry rail 25 ″ and the departure preventing protrusion 34a are They are placed staggered.
