Description

  The present invention relates to a board mounting connector in which external connection terminals with respect to a circuit board are arranged in a grid pattern and an alignment correction plate for aligning the connector terminals.

  Several conventional examples of alignment correction plates for ordering connector terminals of a board mounting connector have been disclosed. For example, according to Japanese Patent Application Laid-Open No. 11-121115 (Patent Document 1), a connector body in which connector terminals, which are external connection terminals whose one end is a contact and the other end penetrates a circuit board, are implanted in a plurality of rows, And a bracket for positioning the external connection terminals. The bracket includes a slit for capturing each external connection terminal in the row when the bracket is moved along the first row direction of the external connection terminal arrangement region. 1 terminal alignment plate, and a second terminal alignment plate provided with a slit that captures each external connection terminal in the row when moved in the second row direction intersecting the first direction. A case has been disclosed.

Japanese Patent Laid-Open No. 11-121115 (FIG. 1, FIG. 4, summary)

  According to the “substrate mounting connector and manufacturing method thereof” disclosed in Patent Document 1, the bracket for orderly arranging each terminal is a slit for capturing the terminal in the row direction (insertion / extraction direction of the mating mating connector). And a terminal in the row direction (lateral to the insertion / extraction direction of the mating mating connector) provided with a slit so as to intersect the slit of the first terminal alignment plate The bracket is formed by overlapping the second terminal alignment plate to be captured, but the terminal alignment plates are in close contact with each other except the slit portion provided in the first terminal alignment plate and the second terminal alignment plate. , The contact area is large. In the part where the alignment plates overlap each other, the alignment plate molding oil, moisture absorption, and environmental temperature change due to long-term storage after manufacturing the connector, the molding oil and moisture exert an adhesive action, making it difficult to separate the alignment plates.

  In addition, a bracket with two terminal alignment plates is press-fitted at the position of the board mounting piece, and when the connector terminal is soldered to the board with the bracket attached, the bracket is melted by the soldering heat and the two pieces are joined. In addition to making it difficult to separate the alignment plates, there are problems that the bracket is hindered and the soldering of the board joint portion of the connector terminal is hindered and the connection reliability is lowered.

  The present invention has been made to solve the above-described problems, and a first object of the present invention is to provide a molding oil for forming two terminal alignment plates which are combined after the connector is mounted on a board. The structure is such that the terminal alignment plate can be easily separated and removed even after long-term storage after manufacturing the connector and the connector, and it is excessive in the soldering area of the connector terminal due to the terminal restraint by the plate and the difference in expansion coefficient between the terminal and the board. The goal is to avoid stress. A second object of the present invention is to suppress and reuse (recycle) the terminal alignment plate from being melted or deformed by soldering heat when soldering the connector terminals after board mounting.

  A board mounting connector according to the present invention has a connector body in which connector terminals, which are external connection terminals penetrating a circuit board, are implanted in a plurality of rows, and an alignment plate for positioning the external connection terminal group, The alignment plate crosses the first column direction, the comb-shaped first terminal alignment plate that captures each terminal group in the first column when moved along the first column direction of the terminal group. A comb-shaped second terminal alignment plate, and the two terminal alignment plates are connected to each other at the bases of the protrusions extending in a comb shape to form an integrated terminal alignment plate. The outer peripheral portion is L-shaped so as to be a part of the frame, and the L-shaped depressions face each other to constitute an integral frame. In addition, a depression (crossing jaw) is provided in one plate of the overlapping portion where the plates intersect, and a groove or a notch is provided in the overlapping portion of the other plate so that the comb-shaped protrusions are three-dimensional in a lattice shape. It is designed to be combined at the top and bottom.

  According to the present invention, since the portion connecting the protrusions extending in a comb shape is L-shaped and each terminal alignment plate is combined to form the frame, the contact area between the plates is reduced. . Also, at the part where the plates intersect and overlap each other, a recess (crossing jaw) is provided on one plate, and a groove or a notch is provided on the other part of the other plate to reduce the part where the plates are in close contact. Therefore, the portion where the bonding action due to the molding oil and moisture absorption at the time of molding the terminal alignment plate and the environmental temperature change due to long-term storage is reduced, so that the separation property of the terminal alignment plate is improved.
