The present invention relates to a connector assembly, and more particularly, to a connector assembly provided with a cover for protecting the connector and guiding the withdrawal direction of the wire connected to the connector.

In general, the connector is composed of a connector housing and a terminal, and is widely used in power circuits such as washing machines, refrigerators, or automobiles. The use of the connector in these electrical and electronic devices has the advantage that a plurality of parts can be assembled separately and then inserted into the final product, thereby greatly simplifying maintenance work as well as device manufacture.

The connector housings are electrically connected to each other through coupling with a mating connector. More precisely, the terminals provided in the connector and the terminals of the mating connector come into contact with each other to electrically connect the two. That is, an insertion space is formed inside the connector housing to penetrate back and forth inside the connector housing. A plurality of terminals are inserted and fixed in the insertion space. To this end, the insertion space is provided with a terminal position support (Terminal Position Assurance). The terminal holder prevents the terminal provided inside the connector housing from being pushed in the opposite direction of the coupling direction by the terminal of the mating connector when the male and female connectors are coupled.

A cover is coupled to the connector housing configured as described above. The cover protects the connector and the terminal, and serves to guide the drawing direction of the wire connected to the terminal and drawn out.

However, the above-described conventional connector assembly has the following problems.

The terminal holder provided inside the connector housing has a problem in that its form is complicated and the amount of work required to manufacture the connector housing is increased. In addition, the terminal holder is difficult to install in the connector housing, so that the defective rate of the product is increased, workability is reduced.

In addition, the cover is coupled to the connector housing in the state in which the connector housing, the terminal, and the terminal retainer are coupled, there is a problem that the number of work is increased as the two coupling processes are performed separately.

Accordingly, an object of the present invention is to solve the problems as described above, and to provide a connector assembly in which a terminal holder is formed to prevent the terminal from being pushed by the terminal of the mating connector on the cover.

According to a feature of the present invention for achieving the object as described above, the present invention is formed with an insertion space in which the terminal is seated therein, a hooking jaw is formed on the outer surface, at least one side surface is opened and orthogonal to the insertion space A connector housing extending along a direction to extend through the insertion space so as to communicate with the insertion space; The inner space is formed to surround the connector housing, the hook hook coupled to the hook jaw on both sides and the cover is inserted into the through-channel terminal supporting ribs to support the terminal is formed, the insertion The terminal coupled to the space is fixed by a terminal support rib inserted into the through channel.

The cover is provided with a shielding plate for shielding one side of the connector housing corresponding to the insertion space, and a wire drawing space for guiding a drawing direction of the wire connected to the terminal, and the shielding plate corresponding to the insertion space. A plurality of through holes is formed.

The hooking jaw and the through-channel and the hooking hook and the terminal support rib are formed at both sides of the connector housing and the cover, respectively.

One side of the terminal support ribs is formed to extend in the extending direction of the terminal support ribs so that the protrusions protrude, and one side of the through channel is formed with a support end on which the protrusions are supported.

In the present invention, both sides of the connector housing are formed by long recesses in communication with the insertion space therein, and both side surfaces of the cover are formed by protruding terminal support ribs inserted into the through channels. Therefore, as the terminal coupled to the connector housing is firmly coupled by the terminal support ribs, the electrical contact between the terminal and the terminal of the mating connector is improved, thereby increasing the operational reliability of the connector assembly.

Further, as the protrusion formed on the terminal support rib is supported on the support end formed in the through channel, the coupling force between the connector housing and the cover is improved, thereby preventing the flow between the connector housing and the cover due to external force. .

In addition, in the present invention, since it is not necessary to perform a task of mounting a separate terminal holding portion inside the connector housing, the working time is shortened and workability is improved.

Hereinafter, the operation of the connector assembly according to the present invention having the configuration as described above will be described in detail with reference to FIGS.

3 is a perspective view illustrating a state in which a connector housing, a terminal, and a cover constituting an embodiment of the present invention are coupled, and FIG. 4 is a cross-sectional view taken along line C-C 'of FIG.

First, the operator couples the terminal 20 to the insertion space 11 ′ of the connector housing 10. At this time, the coupling portion 22 of the terminal 20 is inserted through the through channel 13 of the connector housing 10 until the coupling hole formed in the coupling portion 22 is coupled to the lance and fixed. As a result, the body 21 of the terminal 20 is positioned to correspond to the through channel 13.

In this state, the operator couples the cover 30 to the connector housing 10. At this time, the operator is located in the through channel 13 of the connector housing 10 in a state where the wire (w) connected to the terminal 20 is positioned to be drawn out through the wire drawing space 30 'of the cover 30. The terminal support rib 33 of the cover 30 is inserted to fit well.

When the connector housing 10 and the cover 30 are coupled, the hooking jaw 12 of the connector housing 10 comes into contact with the hook hook 31 of the cover 30. Since the hook hook 31 can be elastically deformed by the deformation slit 31 ', the operator overcomes the elastic force of the hook hook 31 to couple the connector housing 10 and the cover 30 to each other. At this time, the hook hook 31 is elastically deformed to be away from the connector housing 10 by being guided to the inclined guide surface 12 ′ of the hook jaw 12. Subsequently, when the connector housing 10 and the cover 30 are completely engaged, the hook hook 31 is returned to its original state. Accordingly, the hook groove 32 and the hook jaw 12 of the hook hook 31 are engaged with each other to fix the connector housing 10 and the cover 30. This state is shown in FIG. 3.

The state in which the connector housing, the terminal and the cover are coupled as described above will be described in detail with reference to FIG. 4.

First, the terminal 20 is first fixed by the lance. However, when the terminal 20 is coupled only by the fixing force of the lance, the terminal 20 is pushed in the opposite direction of the coupling direction in the process of coupling with the terminal of the mating connector. As the terminal 20 and the terminal of the mating connector are incompletely coupled, the electrical connection between the connector assembly and the mating connector is also incomplete. Therefore, in the present embodiment, the terminal 20 is secondarily fixed by the terminal support rib 33 formed on the cover 30. That is, since the insertion space 11 'and the through channel 13 of the connector housing 10 are formed to penetrate each other, the body portion 21 of the terminal 20 inserted into the insertion space 11' It is inserted into the terminal support rib 33 of the cover 30, the rear end of the coupling portion 22 is fixed to the terminal support rib 33 by walking. Thus, the terminal 20 is coupled in a firmly fixed state in the process of coupling with the terminal of the mating connector. Thus, the connector assembly and the mating connector are electrically securely coupled. In addition, as the protrusion 33a of the terminal support rib 33 is supported by being supported by the support 14 formed in the through channel 13, the cover 30 and the connector housing 10 are firmly coupled to the outside. Due to the flow of the bond is prevented from being released.

The scope of the present invention is not limited to the embodiments described above, but is defined by the claims, and various changes and modifications can be made by those skilled in the art within the scope of the claims. It is self evident.

In the illustrated embodiment, as the insertion space 11 ′ is formed in two rows, through channels 13 and terminal support ribs 33 are formed on both sides of the connector housing 10 and the cover 30, respectively. Explained. However, when the insertion space 11 ′ is formed in one row, the through channel 13 and the terminal support rib 33 may be changed to be formed only at one side of the connector housing 10 and the cover 30.

In addition, the illustrated embodiment has been described that the hook jaw 12 and the hook hook 31 are formed on both sides of the connector housing 10 and the cover 30, respectively, but the specifications of the connector housing 10 and the cover 30 It can be changed to be formed only on one side according to.
