A support having a taper is provided. And the elastic engagement part (elastic locking piece) of the connector of patent document 1 is the said shape, and in order to suppress the fall of rigidity, ensuring the ease of bending deformation, both sides of the width direction in a support part This portion has a structure that protrudes greatly in the thickness direction of the elastic engagement portion (elastic locking piece). As described above, since there is a support portion in which the portions on both sides in the width direction protrude greatly in the thickness direction of the elastic engagement portion (elastic locking piece), the elastic engagement portion (elastic locking piece) of the connector of Patent Document 1 In the case of bending deformation, the support part easily comes into contact with the opposing wall part in the housing. For this reason, the connector of patent document 1 has the problem that it becomes easy to produce the restriction | limiting of the amount of bending deformation of an elastic engaging part (elastic locking piece).

  In view of the above circumstances, the present invention can suppress the decrease in rigidity while ensuring the ease of bending deformation in the elastic engagement portion, suppress the complication of the shape of the elastic engagement portion, and It is an object of the present invention to provide a connector that can alleviate the restriction on the amount of bending deformation of the joint.

(1) A connector according to an aspect of the present invention for achieving the above object is provided with a terminal and an insertion port into which the terminal is inserted, and a housing for holding the terminal inserted from the insertion port And is provided so as to extend in a cantilever shape in the housing, and is elastically deformed by bending with the terminal inserted from the insertion port, and is elastically recovered after being elastically deformed to be engaged with the terminal. And an elastic engagement portion. In the connector according to an aspect of the present invention, the elastic engagement portion is integrally provided side by side in the thickness direction of the elastic engagement portion, and the first beam portion and the second beam are different from each other in the width direction. The first beam portion is provided as a portion extending on a region side where the terminal is inserted in the region in the housing, and the second beam portion is the elastic engagement in the region in the housing. Provided as a portion extending on the side of the region where the portion is elastically deformed and bent, and the terminal protrudes in a direction perpendicular to the direction in which the first beam portion extends and the terminal And a projecting portion that contacts and engages, and the width dimension of the second beam portion is larger than the dimension of the first beam portion in the width direction.

  According to this configuration, the terminal inserted from the insertion port of the housing comes into contact with the protruding portion on the distal end side of the elastic engagement portion extending like a cantilever in the housing. As a result, the elastic engagement portion is elastically deformed and bent, and further elastically recovers after elastic deformation and engages with the terminal at the protruding portion. A terminal is hold | maintained at a housing because a terminal engages with an elastic engaging part.

  And according to said structure, the 1st beam part and 2nd beam part from which the dimension of the width direction mutually differs are provided integrally along with the thickness direction of the elastic engagement part, and a terminal inserts in the 1st beam part. The second beam portion is configured to extend on the region side where the elastic engagement portion is elastically deformed and bent. And the dimension of the width direction of the 2nd beam part is set larger than the dimension of the width direction of the 1st beam part. Therefore, the elastic engagement portion of the connector having the above-described configuration is provided such that the portion of the first beam portion extending on the region insertion side in the region in the housing has a small width dimension and a narrow width. The portion of the second beam portion extending on the region where the elastic engagement portion in the region within the housing is elastically deformed and bent is provided as a portion having a large width dimension and a wide width. For this reason, according to said structure, the elastic engagement which can aim at suppression of a rigid fall with a wide 2nd beam part, ensuring the ease of bending deformation in the 1st beam part with a narrow width | variety. The structure of the part can be realized. And according to said structure, since the elastic engagement part is comprised by the simple shape in which the 1st beam part and 2nd beam part from which the dimension of the width direction differs were arranged in the thickness direction, and elastic engagement part was comprised. Complicating the shape of the joint is suppressed.

  Further, in the elastic engagement portion (elastic locking piece) of the connector of Patent Document 1, since the support portion that protrudes greatly in the thickness direction is provided on both sides in the width direction, the support portion at the time of bending deformation, It is easy to come into contact with opposing wall portions in the housing, and the amount of bending deformation of the elastic engaging portion (elastic locking piece) is likely to be limited. However, according to the above configuration, the elastic engagement portion has a shape in which the first beam portion and the second beam portion having different dimensions in the width direction are integrally provided side by side in the thickness direction, and thus protrudes greatly in the thickness direction. There is no part to do. For this reason, according to said structure, the restriction | limiting of the bending deformation amount of an elastic engagement part can be eased.

  Therefore, according to the above configuration, the rigidity of the elastic engagement portion can be easily prevented from being deformed while suppressing the decrease in rigidity, the complexity of the shape of the elastic engagement portion can be suppressed, and the elastic engagement portion It is possible to provide a connector that can alleviate the limitation of the amount of deformation of deformation.

  In addition, according to said structure, as mentioned above, the elastic engagement part is comprised by the simple shape by which the 1st beam part and 2nd beam part from which the dimension of the width direction differs were integrally provided along with the thickness direction. Therefore, complication of the shape of the elastic engagement portion is suppressed. For this reason, simplification of the structure of the metal mold | die for forming the housing provided with the elastic engaging part can be achieved. Further, since the elastic engagement portion has a simple shape in which the first beam portion and the second beam portion having different dimensions in the width direction are integrally provided side by side in the thickness direction, the left and right dies are used as the mold of the housing. Therefore, it is possible to easily realize only the front and rear molds.

(2) In the connector, a plurality of the elastic engagement portions are provided, and the plurality of elastic engagement portions are configured as two elastic engagement portions arranged in the height direction of the housing. The second beam portion of one of the elastic engagement portions and the second beam portion of the other elastic engagement portion of the elastic engagement portion unit are opposed to each other in the height direction of the housing. You may do it.

  According to this configuration, in the elastic engagement portion unit, the second beam portion of one elastic engagement portion and the second beam portion of the other elastic engagement portion face each other in the height direction of the housing. For this reason, in the housing, the partition wall between the region where one elastic engagement portion bends and the region where the other elastic engagement portion bends is omitted, and the regions where the other elastic engagement portions bend are effectively space-efficiently. It can be used for. Thereby, a some terminal and an elastic engagement part can be more densely arranged in a housing, and can be arranged efficiently, and the further size reduction of a connector can be attained. Further, since the partition wall between the region where one elastic engagement portion bends and the region where the other elastic engagement portion bends can be omitted in the housing, a housing provided with a plurality of elastic engagement portions is formed. Therefore, it is possible to further simplify the structure of the mold for the purpose.

(3) In the connector, a plurality of the elastic engagement unit may be provided, and the plurality of elastic engagement units may be arranged side by side in the width direction of the housing.

  According to this configuration, a plurality of elastic engagement unit units that are configured by two elastic engagement units that can effectively utilize a region where each other bends in the height direction of the housing in a space efficient manner are arranged in the width direction of the housing. Be placed. For this reason, more terminals and elastic engagement portions can be arranged more densely and efficiently, and the connector can be further miniaturized.

The second beam portion of the elastic engagement portion may be arranged so as to be adjacent to each other through a space.

  According to this configuration, the terminals adjacent in the width direction of the housing are partitioned by the partition wall portion. For this reason, it is prevented that the adjacent terminals contact in the width direction of a housing. And according to said structure, the partition wall part which partitions off between the terminals adjacent in the width direction of a housing extends only to the position facing the 1st beam part of an elastic engagement part, and is adjacent in the width direction of a housing. The second beam portions of the matching elastic engagement portions are arranged so as to be adjacent to each other through a space. That is, there is no partition wall portion between the second beam portions adjacent in the width direction of the housing. For this reason, the 2nd beam part wider than the 1st beam part can be arrange | positioned in a housing, using the area | region where a partition wall part does not exist efficiently and efficiently. Therefore, the plurality of elastic engagement portions can be efficiently arranged in a more dense manner in the width direction of the housing. Thereby, a some terminal and an elastic engagement part can be more densely arranged in a housing, and can be arranged efficiently, and the further size reduction of a connector can be attained.

(5) In the connector, the second beam portion is configured so that a dimension in a thickness direction of the elastic engagement portion increases toward a base side of the elastic engagement portion extending in a cantilever shape. It may be.

  According to this configuration, the thickness dimension of the second beam portion is directed toward the base side where the bending moment generated by the biasing force from the terminal acts more greatly when the terminal abuts on the protruding portion and the elastic engagement portion bends. It is set to be large. For this reason, in the second beam portion, to realize a structure in which the cross-sectional area is gradually increased toward the base side where the bending moment at the time of bending deformation of the elastic engagement portion acts greatly, and the generated stress is efficiently reduced. Can do. Thereby, the further suppression of the fall of rigidity can also be aimed at, ensuring the ease of the bending deformation in an elastic engagement part. Moreover, since the amount of deformation of the elastic engagement portion becomes considerably smaller toward the root side, the state where the restriction on the amount of deformation of the elastic engagement portion is relaxed can be easily maintained.

  According to the present invention, it is possible to suppress the decrease in rigidity while ensuring the ease of bending deformation in the elastic engagement portion, to suppress the complexity of the shape of the elastic engagement portion, and to further reduce the amount of bending deformation of the elastic engagement portion. It is possible to provide a connector that can alleviate this limitation.
