Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector which can be fitted into one connector housing without twisting the other connector housing.

[0002]

2. Description of the Related Art In FIG. 6, a connector device comprises a male connector housing 1 made of synthetic resin, a female connector housing 3 made of synthetic resin having a fitting hole 2 for fitting and housing the male connector housing 1. Consists of From the rear surface 4 of the male connector housing 1, female metal terminals 5 (hereinafter referred to as "female terminals") are inserted into predetermined insertion holes. Reference numeral 8 denotes an insertion hole provided in the front end face 6 for receiving a metal terminal on the other side. The mating metal terminal is inserted and fixed in a predetermined insertion hole provided in the rear surface 7 of the female connector housing 3. The tip of the mating metal terminal is a plate-shaped male terminal, which projects into the fitting hole 2.
As a result, when the male connector housing 1 is fitted into the female connector housing 3, the insertion hole 8 accommodates the male terminal and achieves electrical connection. A first rib 9 and a sub-rib 10 are provided on an upper side surface between the rear surface 4 and the front end surface 6 of the male connector housing 1 so as to extend in a direction in which the male and female connector housings 3, 1 are fitted. On the other hand, the male connector housing 3 is provided with a first rib groove 11 for guiding the first rib 9 and a sub rib groove 12 for guiding the rib 10. These first ribs 9, 9 are for fitting the male connector housing 1 to the female connector housing 3 smoothly. Therefore, the fitting direction is oblique to the fitting direction, that is, the male connector housing 1 is forcibly pushed into the female connector housing 3 to prevent the housings 1 and 3 from being twisted and fitted with each other. , Formed to prevent fitting in the twisting direction. The connector was assembled as follows. First, the female terminal 5 is inserted into the male connector housing 1 in advance and integrated. Similarly, the male terminal is inserted into the female connector housing 3 and integrated. As shown by the dashed line, the male connector housing 1 has the front end face 6 enter the fitting hole 2 from the front end face 13 of the front opening of the female connector housing 3. At this time, the ribs 9 and 10 are connected to the female connector housing 3.
Are guided by the predetermined first rib groove 11 and sub rib groove 12, and the male and female connector housings 1, 3 are united to obtain a connector.

[0003]

However, in the conventional apparatus, as shown in FIGS. 7 and 8, first ribs 9, 9 for preventing the fitting in the twisting direction are formed. Nevertheless, the male connector housing 1 may be pushed into the female connector housing 3 in a direction oblique to the fitting direction. At this time, the first ribs 9, 9 are fitted into the inner surfaces of the fitting holes 2 other than the first rib grooves 11, 11, but if they are further forcibly pushed into the female connector, the female connector will not be fitted. The male connector housing 1 enters the fitting hole 2 while deforming the lower surface of the housing 3 so as to expand. As a result, even if the male terminal facing the fitting hole 2 is twisted and broken or deformed to be fitted in the correct fitting direction, the male terminal can no longer be fitted because the male terminal is damaged. In some cases, the female connector housing 3 or the like must be entirely replaced, which may lead to a reduction in the efficiency of assembly work of the connector device and an increase in manufacturing cost.

The present invention has been devised in view of the above circumstances, and prevents one connector housing from being forcibly pushed into the other connector housing in the prying direction, so that the other connector housing is fitted. An object of the present invention is to provide a connector provided with a twisting prevention mechanism capable of preventing breakage of a male terminal in a mating hole beforehand.

[0005]

According to a first aspect of the present invention, there is provided a connector having a pair of first ribs along both upper and lower edges of one connector housing. In a connector having a first rib groove for guiding the first rib in the other connector housing and formed so as to fit in the one connector housing, the first and second connector housing upper side surfaces are connected to each other. A second rib having a height higher than the first rib is provided between the ribs and at a position recessed from the front end face, while guiding the second rib to the other connector housing, and Forming a second rib groove having a groove deeper than the one rib groove, wherein when the one connector housing is fitted in the other connector housing in a prying direction,
The second rib is configured to abut on the front end face of the other connector housing to prevent the fitting in the twisting direction.

According to a second aspect of the present invention, there is provided the connector according to the first aspect, wherein the second rib continuously extends to a front end surface of the one connector housing, and the second rib is connected to the second rib. An auxiliary rib lower than the height is provided.

According to a third aspect of the invention, there is provided the connector according to the first aspect, wherein the auxiliary rib is formed at substantially the same height as the first rib.

According to the first aspect of the present invention, the second rib, which is higher than the first rib, is provided on the upper surface of one of the connector housings and at a position recessed from the front end surface. Since the other connector housing is formed with a second rib groove which is deeper than the first rib groove, when one connector housing is to be fitted in the other connector housing in a prying direction, a second rib groove is formed. It can be seen that the two ribs abut against the front end face of the other connector housing and are prying fit.

According to the second aspect of the present invention, since the auxiliary rib having a height lower than that of the second rib is formed so as to extend from the second rib to the front end face of the connector housing, the both ribs are formed. When fitting is performed, the auxiliary ribs are guided in the second groove at the beginning of the fitting, so that a smooth fitting operation can be performed.

According to the third aspect of the present invention, the auxiliary rib provided continuously with the second rib is formed at substantially the same height as the first rib provided on the other connector housing.
The guide is smoothly guided by the second rib groove, and can be brought into a good fitting posture, thereby preventing the fitting in the prying direction.

[0011]

FIG. 1 is a block diagram showing an embodiment of the present invention.
It will be described based on. FIG. 1 is an external perspective view showing the assembly and disassembly of the connector according to the present embodiment. The same parts, members, or equivalent members as those of the above-described conventional device are denoted by the same reference numerals as those used in the above-described conventional device, and the description thereof will be omitted. Only different configurations will be described.

That is, a pair of rib means 15 projecting in the fitting direction is protruded between the first rib 9 and the sub-rib 10 formed on the upper side surface 14 of the male connector housing 1. The rib means 15 includes a second rib 16 and an auxiliary rib 17 extending continuously from the second rib 16 to the front end face 6 and having a lower height than the second rib 16. The second rib 16 is formed such that the height from the upper side surface 14 is higher than the first rib 9 and the sub rib 10. On the other hand, an auxiliary rib 17 that is continuous with the second rib 16 at a step depth from the front end face 6 by L is provided.
A step 151 is formed between the second rib 16 and the second rib 16. The auxiliary rib 17 has substantially the same height as the first rib 9 and the sub rib 10. The female connector housing 3 has a second rib 16
And a second rib groove 18 deeper than the first rib groove 11 is formed.

The auxiliary rib 17 is provided on the male connector housing 1.
Is fitted to the female connector housing 3 at the beginning to facilitate the fitting.
When the two housings 1 and 3 are to be fitted in the twisting direction, the second rib 16 abuts on the front end face 13 of the opening of the female connector housing 3, so that further fitting in the twisting direction cannot be performed. That's what we do. Reference numeral 19 denotes a locking claw that locks the locked portion 20,
By engaging the locking claw 19 with the locked portion 20 at the time of fitting,
The purpose is to prevent the connection between the male and female connector housings 3, 1 from rattling.

The operation of the embodiment will be described. When the male connector housing 1 is normally fitted into the female connector housing 3, the auxiliary rib 17 of the rib means 15 is in the second rib groove 18, and the first rib 9 and the auxiliary rib 10 are respectively in the second rib groove 18. It fits into one rib groove 11 and sub groove 12. By further pushing, the second rib 16 also enters the second rib groove 18. Accordingly, the male and female connector housings 3, 1 can be fitted without damaging the male terminal at all, thereby completing the connector.

On the other hand, when the male connector housing 1 is erroneously fitted into the female connector housing 3 in the twisting direction as shown in FIGS. The female connector housing 3 is deformed so as not to fit into one rib groove 11 but to be fitted into the ceiling of the fitting hole 2 so as to expand outward. However, at this time, the second rib 16 abuts on the opening front end face 13 of the female connector housing 3 which has been enlarged and deformed. As a result, the male connector housing can no longer be pushed into the female connector housing, and the male terminal in the female connector housing 3 can be reliably prevented from being damaged. In this case, the female connector housing 1 can be once removed from the female connector housing 3 and separated, and can be newly fitted to the female connector housing. Therefore, it is possible to improve the efficiency of the fitting and assembling work of the male and female connector housings 3, 1 and to obtain a connector device with a low manufacturing cost.

Although the present embodiment has been described in detail, the specific configuration is not limited to this embodiment, and even if there is a design change or the like without departing from the gist of the present invention, the present embodiment will be described. Included in the invention. For example, in the above embodiment,
Although the rib means 15 for preventing prying has a boundary 151, the rib means 15 may have a boundary 151, that is, a shape having no step as shown in FIG. That is, it may be formed only on the second rib 20 having a height corresponding to the second rib 16 without the auxiliary rib 17.
Further, the rib means 15 for preventing prying is provided on the male connector housing 1 and the second rib groove 18 engaging with the rib means 15 is provided on the female connector housing 3, but the rib means 15 is provided on the female connector housing. The second rib groove 18 may be provided on the male connector housing 1 side.

[0017]

As described above, according to the first aspect of the present invention, even if one connector housing is slightly fitted due to the deformation of the other connector housing due to the twisting due to the fitting in the twisting direction. The second rib abuts on the front end face of the other connector housing, so that it cannot be fitted any more,
This has the effect of reliably preventing twisting. According to the second aspect of the present invention, since the auxiliary rib lower than the second rib is provided continuously from the front end surface of the one connector housing, the auxiliary rib is also provided at the initial stage of the fitting. Are guided by the rib grooves of the first embodiment, so that the fitting can be smoothly performed. According to the third aspect of the present invention, since the auxiliary rib is formed at substantially the same height as the first rib, the auxiliary rib is smoothly guided into the second rib groove, and has a good fitting posture. To prevent fitting in the twisting direction.
